Title: Contactless ignition device for internal-combustion engine
Inventor: SAGA TOSHIHIRO
IPC: F02P5/155
Filed: 1984-10-03
Abstract: PURPOSE:To perform a stable ignition operation even at a low speed by providing a rotation fluctuation countermeasure circuit for using a low-speed fixed position as the ignition timing by charging a calculating capacitor in an ignition timing control circuit. CONSTITUTION:In an ignition timing control circuit 13, the output of a comparator 100 is used as the set signal of a flipflop 300 with a timer concurrently serving as a rotation fluctuation counter-measure circuit. With analog switches 600, 700 both opened, a calculating capacitor 108 is charged with the constant current ic of a constant-current circuit 400. At a low speed, the voltage of the calculating capacitor 108 is prevented from being decreased to the reference voltage. Accordingly, ignition can be reliably performed at a low-speed fixed position.

Title: Photoelectric transducer for optical character reader
Inventor: SATOU MASUJI
IPC: G06V10/12
Filed: 1981-12-25
Abstract: PURPOSE:To miniaturize the titled photoelectric transducer, by forming a reddish orange LED array of 605-700nm center wavelength for a light source for a character reader in which photodetecting elements are arranged into an array and using mainly CdSe for the active layer of the array of photodetecting elements. CONSTITUTION:An original 2 is irradiated by a light source 1, and this reflected light is led to a photoconductive element array 3 through an optical guide system 4 containing a Selfoc lens, etc. The light source 1 uses a reddish orange LED array of 605-700nm center wavelength, and the array 3 uses a mixed crystal containing mainly CdSe. The red and vermilion colors have >=590nm center wavelength and have a reflection factor approximately equal to that of the fine white paper. A small reflection factor which is almost equal to that of black colors is obtained with <=570nm wavelength. Thus the red group colors can be dropped out without using any filter, and the black and blue colors can be detected with high contrast for a character reader. In such a way, the size of the reader can be reduced.

Title: Liquid crystal display element
Inventor: TERADA MICHIHIRO
IPC: G02F1/1339
Filed: 1985-09-20
Abstract: PURPOSE:To improve display quality by dispersing seal material with which coloring matter is mixed on a display surface as spacers. CONSTITUTION:Black coloring matter is mixed with the seal material which adheres two glass substrates together and said seal material is dispersed on the display surface outside a turn-on display part to hold the gap between the two glass substrates uniform. Namely, black coloring matter is mixed with the seal material and printed on the glass substrates. In this case, the printing is not limited to the place where liquid crystal illuminates for display. Those printed glass substrates 1 are combined and a liquid crystal material 4 is injected into the gap, which is sealed. A negative transmission type display is improved in appearance because the seal material with which the coloring matter is mixed is dispersed on the display surface.

Title: Semiconductor device
Inventor: FUJII SHIGERU
IPC: H01L21/822
Filed: 1984-10-05
Abstract: PURPOSE:To certainly perform the test for certifying normal or defective chip output signal by connectably arranging a first chip having output terminal, input terminal, control terminal and data selection circuit and a second chip which becomes a dummy circuit for the purpose of signal sending and receiving between them. CONSTITUTION:To a first chip (a) having output terminal O1, input terminal I1, control terminal C1 and data selection circuit S1, a second chip (b), which becomes a dummy, having an input terminal I2 corresponding to output terminal O1, output terminal O2 corresponding to input terminal I1, control terminal C2 corresponding to control terminal C1 and data selection circuit S2 is arranged adjacently. In case the input signal is indicated as I, output signal as O and control signal as C corresponding to the terminal symbols, and the test is carried out by setting signal C of each chip to high level, selecting the signal O with the circuit S and inputting it to the dummy circuit when only one chip is used, thereby it can be judged whether each chip outputs normal output signal O or not even if both chips are not connected. When both chips are connected, the signal C of each chip is set to low level and the signal I selected from the circuit S can be obtained.

Title: Disk opening and closing device
Inventor: YAMAZAKI TAKAYOSHI
IPC: G11B17/032
Filed: 1988-08-25
Abstract: PURPOSE:To reduce the cost and to improve the working property of the assembling work of the title device and at the same time, to prevent occurrence of abnormal sounds and deformation by using a torsion coil spring as a spring device and providing a front and intermediate fulcra by bending one arm of the spring at an obtuse angle on the middle and providing inflection point of elastic constant. CONSTITUTION:When an operation button 8 is pressed, a sliding piece 9 retreats and a lock is unlocked. In addition, since the repulsing force of a torsion coil spring 12 predominates the attracting force of the magnet 6 of a disk lid 4, a disk holding device 5 is separated from a turntable 2. When the torsion coil spring 12 opens, its fulcrum moves from an intermediate fulcrum 12b to a front fulcrum 12a and the length of the acting arm of the spring 12 changes from the one shown by the dimension line (a) to the one shown by the other dimension line (b). Therefore, the elastic constant of the spring 12 changes as the fulcrum moves and the repulsing force of the spring 12 is reduced to almost half. As a result, the disk lid 4 is slowly opened. Thus occurrence of abnormal sounds and deformation can be prevented and in addition, the working property of the assembling work can be improved and the cost can be reduced.

IPC: H02M3/155
Filed: 1987-08-24
Abstract: PURPOSE:To stabilize an output voltage by clamping said voltage directly with a Zener diode for controlling it. CONSTITUTION:A self-excited step-down type chopper regulator controls an output voltage by controlling the ON-OFF period of a switching transistor(Tr) 11, and is composed of a flywheel diode 14, a smoothing inductor 15, a driving Tr 12 and others. In this case, there is provided a voltage clamping circuit for clamping an output with a voltage determined by a Zener diode 17 and a resistance 19. Then, Tr 18 is connected with the base of Tr 12, and when an output voltage is going to exceed the operating voltage of said Zener diode 17, Tr 18 is turned ON and Tr 12 is turned OFF to set Tr 11 to OFF. Thus, a voltage higher than a clamping voltage is not generated at an output end.

Title: Execution process tracking method for function type language
Inventor: KIMURA YASUNORI
IPC: G06F9/44
Filed: 1983-11-09
Abstract: PURPOSE:To facilitate easy debugging by producing the interruption of a microprogram level immediately before the 2nd evaluation after the 1st evaluation, and displaying an equation to be subjected the 2nd evaluation at a terminal in an interruption processing routine. CONSTITUTION:A 1-bit field F showing the propriety for acceptance of an interruption of a microprogram level is provided within a microinstruction. When 1 is written to the field F, said interruption is accepted. While the acceptance is inhibited for the interruption if 0 is written to the field F. For a register 14 where various interruption factor flags f1, f2- are set up, ''1'' is set up previously in the column of the flag f1 showing that an equation once evaluated is printed out and before the execution of a program. Under such conditions, a program 10 is executed. Then an interruption is accepted when the execution order of the program 10 reaches a microinstruction 12. Thus an interruption processing routine works to look at each flag column of the interruption factor register 14. Then an equation (showing the result of the 1st evalutation along with an equation to be evaluated in the 2nd time) immediately preceding the flag f1 is displayed after the set-up of the f1 is known.
