Title: Ccd camera
Inventor: KAWAGUCHI NAGAHIRO
IPC: H04N5/335
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent a substrate voltage terminal from receiving a negative voltage lower than the lower limit voltage by connecting a diode to the terminal. SOLUTION: When a power switch is closed, a negative voltage rises earlier than a positive voltage, and when the power switch is open, the negative voltage falls down slowly more than the positive voltage. Thus, there are periods when only the negative voltage is applied to a camera circuit without application of the positive voltage. A diode D5 is biased forward by the negative voltage outputted from an output terminal SUB of a V driver 22 for the periods an the diode D5 is conductive. Thus, the level of the substrate voltage terminal VSUB of a CCD panel 24 is fixed at a voltage differed from a ground level by a forward voltage VF of the diode D5. In the case that a relation of VF<VL (lower limit) is selected, it is prevented that a negative voltage lower than the lower limit voltage VL is applied to the substrate voltage terminal VSUB.

IPC: H01L29/732
Filed: 1986-06-12
Abstract: PURPOSE:To accelerate the operational speed while reducing power consumption by a method wherein the second thin film between an emitter region and the first semiconductor film to be a base leading-out electrode is selectively etched to isolate the space between base emitter electrodes by making fine gaps. CONSTITUTION:The second thin film 27 is formed on the overall surface between an oxidation preventive film 25 laminated on a P type Si substrate 20 and the first thin film patterns 26 to be selectively removed by an anisotropic etching process. Next, the first semiconductor film 28 to be a base leading-out electrode is formed on the overall surface to be etched using a resist film 29 as a mask and furthermore the residual film 27 is removed by an etching process. Thus, the film 28 and an emitter region are isolated by making fine gaps in selfaligment mode so that the structure may be miniaturized to increase the breakdown strength in the reverse direction of emitter base while reducing the capacity. Furthermore, the film 28 can be provided with specified thickness not to be subjected to low resistance even if an insulation oxide film 30 is made thicker. Through these procedures, a semiconductor device such as a bipolar type transistor, etc., operating at high speed in low power consumption can be manufactured.

Title: Data transmission system
Inventor: NAKATSUGAWA NORIHIKO
IPC: H04L25/49
Filed: 1983-07-26
Abstract: PURPOSE:To decrease the time required for transmission by converting a coded data comprising plural bits into a signal having a voltage value corresponding to the data value, transmitting sequentially the voltage from the transmission side to the reception side and allowing the reception side to restore the voltage into the coded data. CONSTITUTION:A 3-bit coded data outputted from ports P0-P2 are transmitted from a terminal 8a as a voltage whose value is changed in 8 stages. The voltage of the transmission line is received by Zener diodes D1-D6 and a lead 9 via a terminal 8b to drive a transistor (TR) Q7. When a voltage of e.g., 12V is given, the base of the TRQ7 goes to ''H''. Thus, encoder inputs D0-D3 go to ''H'' and D4-D7 go to ''L''. An encoder detects the ''H'' level at the most significant bit and outputs the corresponding signal in binary code from terminals P'0-P'2.
