Title: Dolly
Inventor: AOYANAGI KATSUHIKO
IPC: B61B13/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the body of a dolly from slippage by allowing only a clutch for driving the rear wheels to work when the body is in acceleration, and permitting another clutch for front wheels solely to operate when in deceleration. CONSTITUTION:When a dolly is run in the A direction, power is supplied only to a clutch 26 in response to a signal given by a control part 32 and a drive motor 24 is put in operation, with another clutch 27 not power supplied, so that wheels 15 are rotated through an axis 13, and the body 11 runs on a rail 33 in the A direction. When the body 11 is in acceleration, its center of gravity shifts to the back of the body 11 to cause increase of the contact resistance of the wheels 15 with rail 33, and slip is not likely to be generated between them. When decelerative condition is introduced so as to stop, a signal form the control part 32 disengages the clutch 26 and engages the one 27. Thereby the wheels 16 as front wheel are driven, and the center of gravity shifts toward the wheels 16 to cause increase of their friction resistance with the rail 33, so that the body 11 stops in specified position precisely.

IPC: G01N23/22
Filed: 1994-04-13
Abstract: PURPOSE:To adjust the position of a specimen to a focusing point of an x-ray optical system with a relatively simple structure regarding a wavelength dispersion type x-ray spectroscope. CONSTITUTION:Laser light beams are so radiated from a first laser light source 2 and a second laser light source 4 as to make the light beam passage cross at the focusing point of an x-ray optical system. The position adjustment of a specimen 11 to the focusing point of the x-ray optical system is completed by moving the specimen 11 supported by a goniometer 14 to the point where the laser light beams cross mutually. After that, ion beam 1a is radiated from a radiation source 1 and spectroscopic analysis of the x-ray generated from the specimen 11 is carried out by a spectroscopic crystal 3 and the resulting spectral components are detected by a proportional counter 6.

Title: Complex controller
Inventor: SHIKIDA HIDEO
IPC: G06F15/167
Filed: 1988-03-30
Abstract: PURPOSE:To smoothly execute the processing of a sub-controller by reading a state which has been set to a continuation necessary/unnecessary switch provided on the sub-controller, into an area of a continuation flag of a shared storage device, so that when the continuation flag is set in this area, the processing execution of the sub-controller can be continued even if the processing execution of a main controller stops. CONSTITUTION:A central processor 21 of a sub-controller 2 monitors a state of an area 31 of a start/stop flag and an area 32 of a continuation flag of a 2-port memory 3 from a program which has been stored in a ROM 22. In this state, when it is confirmed that '2' has been set to the area 31 of the start/stop flag, whether '1' has been set to the area 32 of the continuation flag or not is confirmed, and when '1' has been set, the sub-controller 2 continues its processing execution as it is, even if a processing operation of a main controller 1 stops. In such a way, even if an interruption reason of the processing is generated in the main controller, the execution of the processing can be continued without interrupting the processing of the sub- controller.

Title: Control of plasma display panel for each dot
Inventor: MISHIERU GE
IPC: H01J11/00
Filed: 1989-03-27
Abstract: PURPOSE: To attain the control of each point in a plasma display panel regulating each pixel by a control electrode and a pair of maintain(MT) electrodes by regulating the polarity and timing of voltage to be impressed to these electrodes. CONSTITUTION: A display pixel consists of a control electrode Xj and a pair of MT electrodes (Yae)i, (Ye) and indicates 1st MT voltage V(Yae), 2nd MT voltage V(Ye) and an optical pulse 30 indicating a difference between both the voltage values and appearing on each end part. Voltage is changed at a cycle of a period T, and when a recording pulse is impressed to the electrode Xj on a part Ti where the polarity signs of both the voltage are reversed, their voltage difference is also added, voltage is suddenly boosted and gas discharge is maintained. On a part Te where the polarity signs are the same, an impressed pulse removes and erases charge existing in the MT electrodes. Since suitable voltage is impressed to all the MT electrodes, the screen can be completely erased or erased in each line.

Title: Expandable hydraulic material
Inventor: OKAMOTO SHUICHI
IPC: C04B18/08
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain an expandable hydraulic material by admixing concrete, mortal or cement paste with calcium oxide-rich fly ash to effect hydration reaction of the calcium oxide to form calcium hydroxide crystals so as to expand the cement paste by the aid of the crystals, and also to contribute to utilization of fly ash as an industrial waste. SOLUTION: The fly ash to be used is such one that the calcium oxide content is higher than the acceptable value specified in accordance with the JIS Standard. This hydraulic material may be admixed with another hydraulic material consisting mainly of calcium oxide, calcium sulfoaluminate or hauyne. The calcium oxide-rich fly ash, when mixed with cement and kneaded with water, forms calcium hydroxide crystals by hydration reaction, leading to expanding concrete or mortar by the aid of the crystals, thereby enabling concrete cracking to be suppressed and filler integrity to be secured after concrete or mortar hardening.

IPC: H02M3/28
Filed: 1979-06-14
Abstract: PURPOSE: To eliminate arc discharge by connecting an eddy current detecting circuit to the output winding of a boosting transformer and stopping the operation of an AC voltage generating circuit by the output of the latch circuit connected to this output.  
     CONSTITUTION: If it is assumed now that arc discharge occurs between a wire 10 and stabilizing plate 11 or between the wire 10 and photosensitive drum 2, pulse current flows in the output circuit and this causes eddy current signal to be generated by an eddy current detecting circuit 13. This signal is input to a pulse counter circuit 14 and when the counter becomes full count, a signal is generated to set the FF of a latch circuit 15. By the output of this FF, a D/A inverter circuit 8 is stopped, thus the protection of load and power source is achieved when the continuous arc discharge occurs.

IPC: G01V9/00
Filed: 1994-04-14
Abstract: PURPOSE:To correct the quantity of light emitted from a light emitting element in a simple circuit constitution. CONSTITUTION:A microcomputer 15 performs the ON control of a switch SW1 when a power supply is turned on. Thus the DC voltage Vcc1 and a current set by a current control circuit 20 flow to an LED 13. At the same time, a current flows to a phototransistor 14 in response to the quantity of light received from the LED 13. Then the voltage V1 set by the current to the phototransistor 14 is fly backed to the control voltage input terminal of the current control circuit 20. Thus the circuit 20 stores the data on the voltage V1 and sets a resistance level to keep a proper quantity of light emitted from the LED 13 based on the stored data. Thus the current flowing to the LED 13 is controlled. As a result, the quantity of light emitted from the LED 13 can be corrected in a simple circuit constitution.
