Patent JP-S63239867-A (JP)
Title: Semiconductor memory cell
Inventor: ARAI KUNIHIRO
IPC: H01L29/812
Filed: 1987-03-27
Abstract: PURPOSE:To obtain a nondestructive reading memory of a sole element with a simple structure at a high speed by forming a source region and a drain region, and at least statically electrically interrupted charge storage region between a channel forming region and a gate electrode. CONSTITUTION:A P-type GaAs layer 103 is etched to a depth having no static continuity with a charge storage layer 112 at source region 107 and drain region 109 at both positions for holding a gate electrode 105. When a source electrode 108 and a drain electrode 110 are electrically continuous, the energy of the layer 112 is reduced lower than the Fermi energy (EF) of the electrode 108, but the electric continuity between the electrode 108 and the region 112 is interrupted by the hill of a potential between a channel forming region 111 and the region 112. Thus, the state that electrons are stored is '1' (or '0') at the region 112, the state that the electrons are not stored is '0' (or '1') to write information, and information can be nondestructively read by the conduction of the different channel forming regions of the two states.

Title: Semiconductor laser
Inventor: OSAKA SHIGEO
IPC: H01S5/00
Filed: 1990-03-19
Abstract: PURPOSE:To suppress temperature rise at the edge of an active layer and to hold an end face crystal in an excellent state by forming an insulating film for insulating a semiconductor layer and an electrode to a region reaching the end face of the active layer in the semiconductor layer, and forming it as a protective film at the end face. CONSTITUTION:An insulating film 8 made of aluminum nitride is integrally formed from the upper surfaces of a p<+->AIGaAs layer 5 and an n-type GaAs layer 7 to a region at least to reach the end face of an active layer 3 by a sputtering method, a CVD method, etc., and a contact hole 9 is formed in a stripelike state exposed at the upper surface of the layer 5 in the film 8. When a current of a threshold value or more flows from a p-type electrode 10 to an n-type electrode direction 11, a laser oscillation occurs in the layer 3, a light is emitted from the edge end face, but since carrier concentration is reduced at the edge of the layer 3 due to nonlight emitting recombination, the light is absorbed to raise its temperature. Generated heat reaches the film 8, the layer 5 and the layer 7 to be radiated to a heat sink H through the electrode 10.

Title: Combustion control circuit for oil burner in abnormality
Inventor: FUJII NOBUSUMI
IPC: F23N5/24
Filed: 1979-06-06
Abstract: PURPOSE: To raise the safety of an oil burner at the stoppage of power supply by connecting condensers different in capacity in parallel to each relay connected in series to a power source.  
     CONSTITUTION: Relays A, B and D are connected in series to a power source, while condensers C 1  and C 2  different in capacity are connected in parallel to the relays A and D. Since each relay A, B and D turns to be self-maintaining in correspondence to the length of time of power stoppage by these connections, the condition of operation of a burner can be decided corresponding to the different time of power stoppage. Therefore, the safety of an oil burner at the time of power stoppage can also be raised.

Title: Recieving stand for green tyre
Inventor: OCHIAI HIDEMITSU
IPC: B29K21/00
Filed: 1982-04-27
Abstract: PURPOSE:To enable even green tyres with different heights to each other to be vulcanized by using a same vulcanizing device by a method in which a table is supported on the base rack of a receiving stand supported on a frame of a vulcanizing device for the unvulcanized tyre being ready for vulcanization by guide rods, and is freely moved up and down by means of a vertically movable cylinder. CONSTITUTION:A receiving stand for unvulcanized tyres is supported pivotably between the chuck position of a loader and the retracting position for replacing metal dies by fitting hinge brackets onto the brackets 14, 14 of the frame 13 side of the vulcanizing device. A disc like table 32 with centering metal pieces 34 for unvulcanized tyres 33 is arranged on the base rack 15, and square sectioned guide rods 39, 39 guided by the piston rod 36 of a cylinder 35 and V-pulleys 38 are fixed to the rear surface of the rack 15. The table 32 is moved up and down between the throwing position for the unvulcanized tyre and the taking up position for the unvulcanized tyre by the cylinder 35. Accordingly, the operation for throwing the unvulcanized tyre onto the table 32 becomes easy. Even unvulcanized tyres with various heights may be vulcanized by using a same vulcanizing device, because the throwing position and the taking up position are able to be changed arbitrarily for the loader with a constant height and a constant stroke.

Title: Protective relay device for transmission line
Inventor: TAKIGUCHI YUTAKA
IPC: H02H3/28
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To lessen the time lag at the time of a blind-spot accident by opening the breaker at its own end when the difference between the quantity of operation and the quantity of control is larger than a certain comparison value, and performing the zeroing of the current that it receives from its opposite end and zeroing of the quantity of control. SOLUTION: A subtraction processor 15 performs subtraction from the quantity of operation to the quantity of control, and a comparator 16 issues relay output 16a and generates an open command to a breaker when the output of subtraction is larger than the constant K, and a pause end detector 24 detects the pause end, and a zeroing processor 17 performs the zeroing. On the other hand, a one shot circuit 25 receives the detection result of the pause and detector 24, and outputs pulse output with a certain width, and a zeroing processor 23 performs the zeroing of the quantity of output control of the quantity-of- control memory 22. Hereby, the output of the subtraction processor 15 goes up, the delay output of the quantity of operation gets over the comparison value K at the same time with occurrence, and the relay output 16a appears.  Accordingly, it can be speeded up by lessening the time delay.

Title: Polarizing grid
Inventor: ISODA YOJI
IPC: H01Q15/22
Filed: 1988-03-28
Abstract: PURPOSE:To obtain a polarizing grid to operate even at the band of polarized millimeter wave or a higher frequency than it by forming the C axis of a crystal of superconducting material in a direction different from the direction of its thickness. CONSTITUTION:A polarizing grid 10 is formed out of high-temperature superconducting material like Y-Ba-Cu-O system ceramic and the direction of a C axis of the crystal is horizontal. It is hard for currents to flow in the direction of the C axis of the crystal, that is, horizontally, the currents flow only vertically, an interval (g) of the currents is the size of a molecule, that is, several tens Angstrom  which is very small, therefore, the polarizing grid 10 transmits vertically polarized waves even at the frequency higher than the millimeter-wave band and has a function to reflect horizontally polarized wave. Thus, the vertically polarized wave and the horizontally polarized wave can be separated at low loss even at a very high frequency band and a feeder circuit becomes simple.

Title: Production of casting mold having hook
Inventor: WATANABE MASATOSHI
IPC: B22C9/04
Filed: 1984-04-12
Abstract: PURPOSE:To prevent inclination of a blank material for a hook during pouring by positioning and holding the blank material for the hook to a sand mold by means of a supporting member. CONSTITUTION:A casting space 3 is formed of a metallic pattern 1 which holds tentatively one end of the blank material 4 for the hook and consists of foamed PE, etc. and the material 4 is supported by the supporting member 10. One end of the member 10 is inserted into the hole 11 of the material 4 and the other end is fixed and held by the sand mold 2. The material 4 is thereby bridged in the casting space 3. The pattern burns and evaporates on pouring of a molten metal through a sprue 5 but one end of the material 4 is supported by the side wall 2a of the mold 2 and the other end by the member 10 and therefore the inclination of the material 4 by the flow of the molten metal is obviated. The material 4 may also be provided in the state of projecting part thereof into the space 3.

Title: Automatic controller for passenger conveyor
Inventor: UEKI YASUO
IPC: B66B25/00
Filed: 1978-06-14
Abstract: PURPOSE: To change a passenger conveyor from an automatic run to a continuous one without stopping the conveyor and immediately change the passenger conveyor from a waiting condition in the automatic run to the continous one.  
     CONSTITUTION: When an automatic run switch 1 is closed, an automatic run instructon relay 3 is energized so that the passenger conveyor is caused to wait in the automatic run. If an output is then generated by an upward passage detectir 10, an upward passager detecction relay 12 is energized to run the conveyor upward. When the output of the upward passenger detector 10 has vanished, the upward passager detection relay 12 is deenergized so that the conveyor is caused to wait in the automatic run. When an upward run switch 4 is closed by a controlling person, an upward run instruction relay 6 is energized to cancel the an automatic run instruction to continue an upward run. Similar processes are executed for a downward run.

IPC: B03C3/12
Filed: 1981-05-13
Abstract: PURPOSE: To enable sending of rectified wind accurately to a charged object by utilizing ionic wind and thereby preventing occurence of turbulent flow in fan blasting.  
     CONSTITUTION: When a plug 56 is connected to a 100V plug socket and the switch 54 is made to ON-state after closing the cover plate of a casing completely, a converter 60 outputs d.c. high voltage from a power source 24 terminal and outputs a.c. high voltage from a current 42 terminal. Consequently, plus high voltage is applied to an acicular ionizing conductor 16 and minus zero voltage is applied to a wind generating electrode. Further, an electric field is generated at the tip of the acicular conductor 16 and a wide extent on the front end face of the electrode 28, and positive corona discharge is generated. A large quantity of ions moves to the electrode 28 by corona discharge, and the air current flows out to outside from a window through the electrode 28, reticular electrode 44 and inside of the casing. At this time, suspended particles are collected by the electrode 28, and another electric field is formed between electrodes 16, 44 and the ions are sent in the direction of the window by rectified wind due to ionic wind phenomenon.

Title: Crystal bearing analysis instrument which utilizes polarization characteristic of raman scattering light
Inventor: IKEDA TAKESHI
IPC: G01N21/84
Filed: 1987-03-25
Abstract: PURPOSE:To simplify an instrument and to improve the accuracy of measurement by disposing a polarizer for polarizing incident light and detecting scattered light between a half mirror for incidence and objective lens. CONSTITUTION:The polarizer 9 for polarizing the incident light and detecting the scattered light is disposed between the half mirror 5 for introduction of the incident light and the objective lens 3. This polarizer 9 selects the specific linearly polarized light from the incident light just before the incident light bent by the half mirror 5 is introduced to the objective lens 3 and, therefore, generation of a deviation between the angle of polarization of the desired incident light and the angle of polarization of the actually projected incident light is obviated. Furthermore, the measurement can be made in the perfectly aligned state of the angle of polarization of the incident light and the angle of polarization of the Raman light, since the polarizer 9 plays the role of both the polarizer of the incident light and the analyzer of the Raman light. The device is thereby simplified and the accuracy of the measurement is improved.

Abstract: PURPOSE:To rewrite tape mark blocks with high reliability by forming a longer interblock gap than that in writing data by a write instruction for the tape mark block. CONSTITUTION:In response to a write instruction for a tape mark block 3, a longer interblock gap 2 than that of a write instruction for a data block 1 is generated and the block 3, while recorded 66 on a tape 64, is read out 67. A recording state is then checked and if an error is found, the tape 64 is reversed to set a timer 65 which indicates the intermediate optional position of the longer gap 2. When the timer 65 indicates the set value or when the block 3 in an error state is read out, a longer gap 2 from each recognition position in the advancing direction is formed newly and the block 3 is rewritten.

Title: Rotary cylinder clamping structure of delivery-takeup machine
Inventor: SATOU HAYASHI
IPC: B65H18/04
Filed: 1979-06-11
Abstract: PURPOSE: To prevent slackening of juncture between a rotary cylinder and a hollow shaft, by cutting differently handed threads on the external and bore sides of the hollow shaft.  
     CONSTITUTION: The external circumference of a hollow shaft 17 and the bore side 26 of a rotary cylinder 14 are screw type of structure. Differently handed threads (left-handed and right-handed) are cut on the internal wall 27 of the hollow shaft 17 and the external wall 26 of the hollow shaft 17, respectively and clamped with bolts 28. When a takeup drum turns clockwise and the threads 26 are right-handed on the hollow shaft 17 and rotary cylinder and when band steel is rolled between the takeup drum and a delivery drum, a relative rotational difference is produced between the hollow shaft 17 and the rotary cylinder 14 and the right-handed screw is slackened, because a reactive force works in the direction opposite to the revolution of the drums. This slackening is canceled by the thread (left-handed) made on the internal wall of the hollow shaft 17, being different from that on the external wall.

Title: Production of glass particles
Inventor: MAKIO KEIZOU
IPC: C03B32/00
Filed: 1987-03-26
Abstract: PURPOSE:To obtain glass particles which have small specific surface area and give good sintered products with a small amount of a binder included, by heating a glass powder in the temperature range from the softening point to the phase-transition point so as to become round. CONSTITUTION:A cylinder 2 is inserted into a vertical type calcinating furnace 1 which is shorter than the cylinder 2. While glass particles 6 are fed by the feeder 3 at the top of the cylinder 2, air is blown from the bottom upward so that the particles are fluidized and fly down through the cylinder 2. Thus, the glass particles are heated by the furnace 1 in the temperature range from the softening point to the phase transition point and their surfaces are made round. The resultant particles 7 has small specific surface area and are converted into glass-sintered products such as base plates for electronic parts with a reduced amount of a binder, because the glass particles have good drapeability.
