Title: Clogging preventive device for combusting device
Inventor: HIROMOTO SHUJI
IPC: F23D14/16
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent a porous mat from being clogged, and at the same time, facilitate the maintenance by a method wherein air which is taken in from an air inlet is introduced to the porous mat while coming into contact with the surface of water which is filled in a recessed part. SOLUTION: Air is introduced by operating a blower fan 4, and at the same time, a combustion gas is discharged from a feeding pipe 5, and the mixed gas is fed to a combustion burner part 1, and at the same time, by an igniting device, a surface combustion is performed by a porous mat 7. Then, by making water in a water pipe 8 flow, a heatexchange is performed at a heat-exchanging part 6, and hot water is obtained. In this case, the air which is introduced from an air inlet part 3, meanders by baffle plates 10a, 10b, and comes into contact with water which is filled in a recessed part 2a by a plurality of times, and dust and dirt, etc., are removed, and then, is fed to the combustion burner part 1 together with the combustion gas.  Also, by using the porous mat 7 wherein a metal fine wire of which the diameter is 100 μm or less is formed into a mat-shape, a uniform combustion can be performed.

Title: Wavelength driving device for spectrophotometer
Inventor: AKITOMO NOBUO
IPC: G01J3/06
Filed: 1982-07-07
Abstract: PURPOSE:To prevent excessive running of a wavelength driving motor, by executing the operation of the motor by a processing means comprising a digital gate circuit and a microswitch, and performing automatic returning by the command from the microprocessor when a power source is turned ON again. CONSTITUTION:When a pulse motor 1 is driven in the forward direction, a driving signal from a terminal 21 drives the motor 1 through a gate 24 and an LSI 9. When excessive running occurs owing to some causes and a slider hits a forward side switch 19, the switch 19 is turned ON and the gate 24 is closed. Then the driving signal from the processor 10 is cut off and the motor is stopped. When the processor 10 receives the information, the processor displays an error message. An operator receives the information and turns OFF the power source once and then turns ON it again. The processor 10 reads the states of the switches 18 and 19, acknowledges the excessive running in the forward direction, and outputs pulses in the reverse direction through a terminal 20. In this way, the pulse motor 1 is made to rotate in the reverse direction and can be returned to the normal position.

IPC: H04B3/23
Filed: 1983-06-30
Abstract: PURPOSE:To attain an inexpensive coder by saturating a coder output to an overload code to a residual difference signal between a real value being larger than a set overload level and an estimated value thereby reducing the dynamic range for the share. CONSTITUTION:An echo cancellor 3 is provided among a reception section 1 and a transmission section 2 at the opposite party and an echo device 4 made of a 4/2-wire converting section viewed from terminals 10, 11. The cancellor 3 consists of a coder coding a transmission signal xj, an operating circuit 6, a decoder 7 decoding an estimated echo line response yj', an analog subtraction circuit 8 subtracting an estimated value yj' from an actual echo response yj, and a coder 9 coding a residual difference signal ej. The overload level of the coder 9 is set lower than the maximum level of the signal ej so as to saturate the output of the coder to the overload code to the residual difference signal ej larger than the set level. Thus, the number of bits of the coder is reduced and the coder is constituted with a low cost.

Filed: 1990-05-07
Abstract: PURPOSE:To easily and speedily correct the contour shape of a character by providing a character/pattern generating means which generates contour lines and paints out the inside of the contour lines by using only discrete contour data. CONSTITUTION:This device is equipped with a storage part 103 for numbers of a sequence of contour points constituting an area and a painted-out area indication data storage part 104.

Title: Engine controlled with respect to number of cylinder
Inventor: IIZUKA HARUHIKO
IPC: F02D17/02
Filed: 1980-08-26
Abstract: PURPOSE: To improve combustion in active cylinders without reducing scavenging performance by permitting idle cylinders to take in and exhaust air during running partially cylinders without thinning exhaust flowing in three component catalyst.  
     CONSTITUTION: When a circuit 19 for controlling the number of cylinders commands partial cylinder running, fuel supply to idle cylinders #4W#6 is cut and then shut-off valves 7, 23 are closed while a exhaust reflux valve 8 and an electromagnetic valve 25 are opened. Thus, air discharged from the cylinders #4W#6 is circulated to an idle intake path 2b to prevent pumping loss. When pressure in the path 2b is lowered by leakage of the shut-off valves 7, 23, the atmosphere is sucked from a check valve 26 to prevent securely pumping loss from increase. Also, since the circulating air does not thin exhaust flowing in a three component catalyst 16, scavenging performance is not degraded.

Filed: 1980-08-26
Abstract: PURPOSE:To improve the life and reliability of a display cell by simultaneously removing the mask and orientation treated film formed on the lead-out electrode parts on a substrate by performing ultrasonic treatment using water. CONSTITUTION:Display electrodes of indium oxide are formed on the inside surfaces of glass substrates 1 and 2 constituting a cell, and electrodes 3 for lead-out are formed on the electrode forming parts 9 of the substrate 1. A self-adhesive cosisting essentially of an epoxy resin and using methyl cellosolve as a solvent is screen printed on the electrodes 3 of the substrate, after which it is calcined to form a mask. Thereafter, the substrate is immersed in a silicic acid soln. and is calcined, whereby an orientation control film is formed. The substrate is then subjected to ultrasonic treatment for one hour in water, whereby the mask agent and the orientation control film are removed. The similar effect is obtained by the ultrasonic treatment of 10min if water of >=60 deg.C is used.

Abstract: PURPOSE:To improve the resolution of a picture reader, by vibrating the optical system vertically to the photoelectric conversion element arrangement direction synchronously with the driving signal which drives the solid sensor array where photoelectric conversion elements are arranged. CONSTITUTION:Original stand 1 is illuminated by light sources 2 and 3, and reflection light 10 is reflected by reflection mirror 5 through lens 4 and is focused onto the chip of CCD 8. Here, when transfer gate signal generator 7 generates one pulse, CCD 8 transfers one-line information to video output 9 and integrates optical information incident onto the cell during the time from transfer completion to input of the next transfer gate signal. Meanwhile, saw tooth wave oscillator 6 oscillates synchronously with transfer gate signal 7. Reflection mirror 5 is vibrated to rotate the other end in the arrow direction with one end as the center by the output of saw tooth wave oscillator 6, thereby vibrating the optical system vertically to the CCD element arrangement direction.

IPC: C21D9/00
Filed: 1979-09-13
Abstract: PURPOSE:To manufacture steel wire rod of excellent straightness, by making plural spiral grooves at equal intervals in the inner surface of a guide for steel wire rod, by cooling the whole surface of the high temp. steel wire rod uniformly with backflow water formed from the cooling water which is sprayed from an internal pipe through which the steel wire rod passes. CONSTITUTION:A cylindrical internal pipe 2 is surrounded at least rear end 7 of its outer periphery with a cylindrical external pipe 1, and a guide 4 for the wire rod is equipped on the inner surface of the rear end 7. High pressure water is sent through a water pipe 5 to one end of vacant gas formed between the pipes 1, 2, and is sprayed through many spray holes 3 made in the pipe 2 in the advancing direction of the wire rod. Because plural grooves 6 are made spirally at equal intervals on the inner surface of the guide 4, the whole surface of the high temp. steel wire rod is cooled uniformly with backflow water in the guide 4. Hence no bending stress due to ununiform transformation, which causes the bending of the steel wide rod, is generated, and steel wire rod having excellent straightness is manufactured.
