Title: Low noise amplifier circuit
Inventor: IGASAKI WATARU
IPC: H03F1/32
Filed: 1991-11-19
Abstract: PURPOSE:To prevent saturation distortion from being caused when an input signal level gets higher in the amplifier circuit where the NF is minimized when the input signal level is low. CONSTITUTION:When a level of an input signal of a low noise amplifier means 1 is less than a threshold level decided optionally, a voltage minimizing the NF is fed from a voltage control regulator 4 to the low noise amplifier means 1 as a power supply voltage and a bias voltage. When the level of the input signal reaches the threshold level or over, a voltage to increase the saturation level of the low noise amplifier means 1 is fed from the voltage controlled regulator 4 to the low noise amplifier means 1 as the power supply voltage and the bias voltage by using an automatic gain controlled voltage from an automatic gain control amplifier means 2 connecting to a post stage of the low noise amplifier means 1 whose level grows higher in response to the level reaching the threshold level or over.

IPC: H04N5/243
Filed: 1989-11-24
Abstract: PURPOSE:To eliminate the defect of deteriorated picture quality due to production of noise and the deteriorated signal S/N by using a signal being the sum of an output signal from a solid-state image pickup element and a signal delayed via a delay circuit for a prescribed time as an output signal of the solid-state image pickup element. CONSTITUTION:A signal from a solid-state image pickup element 10 is amplified first by a signal amplifier 11 and inputted as it is to an adder 13 and delayed for a prescribed time via a delay circuit 12 and inputted to the adder 13. Thus, the waveform of a succeeding pixel signal is added with a waveform of the delay signal and both waveforms are synthesized. Thus, the added signal is used as a pixel signal and given to a low pass filter 14, in which the high frequency component is eliminated. Thus, the amplitude level of the signal after the low pass filter is much increased. Thus, the S/N of the output signal from the processor is improved and the noise in the video signal is reduced.

Title: Mobile object detector, abnormal condition alarming device, and loading chamber opening controller
Inventor: OKADA HIROKI
IPC: G08B13/00
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To easily and surely detect a mobile object. SOLUTION: When a signal from an oscillation circuit 14 is transmitted from an antenna 40, the load on the antenna 20 fluctuates because of a change in electrostatic capacity due to the movement of a mobile object such as a human around the antenna 20. Because of this fluctuation, an oscillation frequency of the oscillation circuit 14 fluctuates. Thus, the frequency fluctuation is detected by means of a frequency fluctuation detecting element 16, and according to this result, the mobile object is detected by means of a determination element 18.

Title: Semiconductor integrated circuit
Inventor: IWASAKI TOMONOBU
IPC: G11C11/34
Filed: 1987-12-03
Abstract: PURPOSE:To prevent malfunction due to capacity division by serially connecting plural transistors, which are turned on by plural signals, between a node and a second power source terminal. CONSTITUTION:Plural transistors Qn0-Qn3, which are turned on by plural signals A0-A3, are serially connected between a node N0 and a second power source terminal Vss. Further, plural transistors Qn0'-Qn2', which are turned on during a precharge period, are serially connected between intermediate nodes N1-N3, which are between the plural transistors Qn0-Qn3, and a second power source terminal Vcc. Accordingly, the respective nodes N1-N3 of transistors Qn0-Qn3 are charged during the precharge period and even when one part of the transistors Qn0-Qn3 is turned on after the precharge period passes, a load moving due to the capacity division is not generated between the node N0 and the respective nodes of the transistors Qn0-Qn3. Thus, the malfunction due to the capacity division is prevented.

Title: Ic card
Inventor: OKITA YOSHINORI
IPC: B42D15/10
Filed: 1988-11-30
Abstract: PURPOSE:To make items other than a requested purpose impracticable without a necessity of inputting a password number by another person by a method wherein an another person use mode in which one time execution is passable is established, an operation passable state is maintained after establishing the mode, and the title IC card is made to reach an operation locked state after end of processing. CONSTITUTION:When an another person mode is established, a processing command P to be requested is inputted with a key. After storing in a memory, an OFF key is inputted and the title IC is lent out. Though the OFF key is inputted by this mode, the operation is not locked and an operation passable state is being kept even without referring to a password number. However, contents capable of being processed is only the processing command P inputted by a person in question. After end of processing, the operation is automatically locked and the IC returns to an initial state. Therefore, processing may be requested on another person without a necessity of counting the password number and further, there is no fear of using the IC card arbitrarily for items other than requested processing.

Abstract: PROBLEM TO BE SOLVED: To improve workability and prevent a dust lip from being damaged by forming a projection section which opens a slide face of the dust lip and a shaft member by pressing on a fluid side to be sealed in the dust lip. SOLUTION: A dust lip 3 of a sealing device is constituted in such a manner that a dust lip 3a on the outside leaves a slide surface of a shaft 201 with a dust lip 3b on the second step as a fulcrum by pressing a projection section 4 by a push section 35. When gas G200 to be sealed in this condition is poured in an arrow direction Al, gas enters an open section 3f from the inside of the push section 35 and enters a reservoir chamber 207 through a groove of the dust lip 3b at the second step, a main lip 2, and a communicating passage as shown by arrow marks A2 and A3. Consequently, the dust lip 3 is not damaged and caught, and the open section 3f which becomes a flow passage of gas can be formed. For this reason, safe and secure gas sealing work can be done, and workability can be improved.
