Patent JP-H0354907-A (JP)
Title: Amplifier device
Inventor: MIKAMURA YASUKI
IPC: H03F1/32
Filed: 1989-07-24
Abstract: PURPOSE:To reduce the saturation degree of a transformer impedance type amplifier and to obtain an output signal having no distortion from a large input light current by opening a by-pass route based upon the potential difference between the input and output of the amplifier to prevent an output voltage from being dropped. CONSTITUTION:The drain and source of an FET Q5 are respectively connected to the input and output terminals of the amplifier 2. The gate of an FET Q6 is connected to the output terminal of the amplifier 2 to obtain an output signal VOUT from the gate. A serial circuit of resistors R1, R2 is connected between the source and ground of the FET Q6 to be a source follower to divide the source voltage and apply the divided voltage to the gate of the FET Q5. When the input light current iPD exceeds a prescribed value, the FET Q5 is turned on and a by-pass current iQ is set up so as to flow into the by-pass. Consequently, the saturation degree of the amplifier 2 can be suppressed without advancing the drop of the output voltage VOUT to a prescribed value or less.

Title: Supercharging pressure controller of internal combustion engine with supercharger
Inventor: AKITA KOICHI
IPC: F02B37/18
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To surely maintain the closed state of a waste gate valve even in the case where intake pressure is improved by controlling the opening area of a variable nozzle. SOLUTION: While an exhaust inflow quantity into an exhaust turbine 107 is being controlled by a variable nozzle 109 in a low speed area, negative pressure to be produced by a vacuum pump 111 to be driven by an internal combustion engine is fed to a waste gate valve actuator 114, whereby a waste gate valve 110 is forcibly closed. Therefore, even in the case where the variable nozzle 109 is adjusted, quickening a flow rate of exhaust gas flowing into the exhaust turbine 107 and supercharging pressure is increased, such a possibility that this waste gate valve 110 might be opened is prevented from occurring, and thus the effect of a rise in this supercharging pressure by the variable nozzle is brought into full play.

Title: Light shield type tablet
Inventor: INOSE SHIGERU
IPC: H01L31/12
Filed: 1984-09-14
Abstract: PURPOSE:To offer a tablet which eliminates the need to collimate a light emitting diode(LED) having independent frequency characteristics with high precision and provides sufficiently accurate position detection with 1:1 coordinates between the LEDs and PDs without scanning LEDs and photodetecting elements(PD) successively by installing the LEDs at opposite positions on the input surface of the tablet and equalizing frequency characteristics of the PDs to those of the LEDs. CONSTITUTION:Light from LED1-alpha-a is not collimated completely, so it has a spread as shown by a hatched part and is made incident on even PD-alpha-a, PD-beta-a, and PD3-gamma-a. The PDs, however, have different frequency characteristics, so the light from the LED1-alpha-a is detected only by the PD3-alpha-a, light from the LED1-beta-a only by the PD3-beta-a, and light from the LED1-gamma-a only by the PD-gamma-a, so that the LEDs and PDs correspond to each other one to one.
