Title: Sample-hold circuit device
Inventor: ITAKURA TETSURO
IPC: G09G3/20
Filed: 1991-01-28
Abstract: PURPOSE:To decrease the errors and fluctuations in output by adopting the constitution to connect an input terminal to the parallel connection of a holding capacity and n channel MOSFET and an output terminal via the series connection of the n channel MOSFET and Schottky diode. CONSTITUTION:A MOS transistor (Tr) 58 is first turned on by a signal phi15 and both terminals of a capacitor 57 are kept at the same potential, i.e., are initialized. The capacitor 57 is charged via a diode (D)56 when a Tr 55 is turned on by a signal phi14. This potential is the value obtd. after the forward voltage drop of the D 56 is subtracted from the potential of an input signal. The charge that the signal phi14 leaks via the overlap capacitor of the Tr 55 and a part of the channel charge of the Tr 55 tend to flow as error charges to the capacitor 57 via the D 56 when the signal phi14 falls to a low level and the Tr 55 turns off. These error charges are, however, negative, the D 56 is reverse biased and the route in which only the Shotkky junction can flow into the capacitor 57 is formed.

Title: Checking system of optical detector
Inventor: SHINOZUKA HIROSHI
IPC: G01J1/42
Filed: 1981-02-26
Abstract: PURPOSE:To simplify the circuit constitution and to reduce the number of connecting lines, by switching the current supplied to a light emitting part and checking the quality of an optical detector based on the result of a deciding  part. CONSTITUTION:In a checking mode, a switch SW is connected to the side of a terminal t2 to turn off a transistor Q. A minor current is supplied to light emitting diodes Sa1-Sa3 to reduce the light emitting volume down to R1. Accordingly, the light volume is reduced to R1 from R2 if some dust sticks to the light emitting or receiving surface or these surfaces are deteriorated. Then the output voltage lowers less than the slice level L1, and as a result, a defect can be checked for an optical detector. In the operation mode, the switch SW is connected to the side of a terminal t1 to turn on the transistor Q. Then a major current flows to the diodes Sa1-Sa3 to obtain the light volume R2, and the output of an amplifier is set at V1.

Title: Semiconductor integrated circuit device
Inventor: YOSHINAGA MAKI
IPC: H03F3/72
Filed: 1983-02-23
Abstract: PURPOSE:To attain the evaluation of characteristic of a transistor (TR) with high accuracy by providing a switch means interrupting a current flowing to a bias circuit of the amplifier TR. CONSTITUTION:In evaluating the characteristic of a TRQ1, a voltage to turn off a TRQ5 is applied to an external terminal Vsw. A diode D3 is back-biased by turning-off of the TRQ5 so as to avoid a current path from being formed to a resistor R4. A current applied from an external terminal IN1 is only a base current of the TRQ1 so as to separate a bias circuit BS from circuit PA of the input stage. Thus, the evaluation of the characteristic of the single TRQ1 is attained.

Title: Electroluminesent phosphor ink for printing
Inventor: TADA MASAKI
IPC: C09D11/00
Filed: 1988-02-10
Abstract: PURPOSE:To obtain the subject ink which does not lose a moisture-absorbing effect, does not attenuate in light even when a moisture-absorbing layer is omitted and can be simplified in a production process, by adding a fine powder of silica gel to an EL phosphor ink.

Title: Diagnostic system for error detecting circuit
Inventor: TAKETOMI MASANORI
IPC: G06F11/08
Filed: 1981-03-02
Abstract: PURPOSE:To diagnose an error detecting circuit easily with a low cost, by inputting normal data from an external device and changing this data for a constant time to diagnose the error detecting circuit. CONSTITUTION:When an FF8 which indicates the diagnostic operation is set by a control part 11 and data is read from a floppy-disc driving FDD1 to an LSI2 for floppy-disc control, a transfer request is generated from the LSI2 to set an FF10. An output O of the FF10 becomes low, and the input of separate data from the FDD1 to the LSI2 is inhibited by a gate 5. Next, when an FF9 is set and the FF8 is reset and a separate clock is inputted from the FDD1, the FF10 is reset through a gate 7, and the inhibition of the gate 5 is released to input data from the FDD1 to the LSI2. By this action, normal data has one bit dropped out and is inputted to the LSI2 from the FDD1, and the LSI2 reports a CRC error, thus diagnosing the error detecting function.
