Title: Load protection device
Inventor: OKAMOTO TETSUYA
IPC: H02J7/00
Filed: 1994-05-25
Abstract: PURPOSE:To suppress output loss when the amount of insolation is small and at the same time protect a load and extend the life regardless of the output increase in a solar cell power supply when the amount of insolation is large by providing a constant voltage circuit for making constant the voltage near the rating of the load between the solar cell power supply and the load. CONSTITUTION:A constant voltage circuit 300 is connected to a solar cell power supply 1 with a ventilation fan device 20 for ventilating a house as a load. An output voltage applied to the ventilation fan device 20 according to the amount of insolation is measured for the cases with and without the constant voltage circuit 300. As a result, when the constant voltage circuit 300 is used, an output voltage applied to the ventilation fan device 2 becomes constant even if the amount of insolation increases and an output voltage increases when there is no constant voltage circuit 300. Therefore, even if an output power exceeding the rating of the load exists when using a solar cell power supply, the voltage becomes constant, thus preventing the load from being damage and extending the life.

Title: Electromagnetic shield system of optical sensor having opening part
Inventor: FUKUDA MINORU
IPC: G01J5/06
Filed: 1989-05-02
Abstract: PURPOSE:To make it possible to block only the passage of harmful electro-magnetic waves effectively without decreasing the transmittance for an incident light signal by providing a shield plate having an opening part whose size is smaller than the specified ratio of the wavelength of an electromagnetic wave whose transmission should be blocked. CONSTITUTION:A sensor has the following parts: a shield plate 3 which is arranged in an optical-sensor main body 1 and has an opening 4 whose size is about 1/2 or less of the wave length of an electromagnetic wave whose transmission should be blocked; and an optical system which condenses a light signal inputted from an opening part 4 of the sensor main body to the size of the opening of the shield plate 3 and passes the signal through the opening 4. An incident light signal 6 is condensed through an objective lens 2 and reaches a detecting and processing part 5 through the opening 4 of the shield plate 3 without attenuation. The electromagnetic wave which is intruded through the opening 4 of the sensor main body is drastically attenuated when the electromagnetic wave passes through the opening 4 of the shield plate which is set at the value that is about 1/2 or less of the wavelength of the electro magnetic wave. The reaching of the electromagnetic wave to the detecting and protecting part 5 in the sensor main body 1 is effectively blocked. Thus, interference on the detecting and processing part 5 is prevented.

Title: Variable gain amplifier
Inventor: TSUKAHARA TSUNEO
IPC: H03F3/345
Filed: 1986-05-19
Abstract: PURPOSE:To contrive broad band and lower power consumption by connecting one stage of a CMOS inverter and another CMOS inverter having feedback to the input/output through a variable resistor in cascade so as to constitute a variable gain amplifier, thereby eliminating the need for a level shift circuit and a capacitor. CONSTITUTION:A unit amplifier 3 consists of complementary inverters 1, 2 connected in cascade and a variable resistor Ef1 and the resistor Rf1 is connected between the input and output of the inverter 2 to form a negative feedback path. Thus, the gain is made variable by the resistor Rf1, and since the input impedance of the amplifier is capacitive due to the input capacitance, no gain effect is caused in case of multi-stage connection because the amplifier of the next stage gives effect on the band via its input capacitance. Thus, the direct coupling malti-stage is attained without a capacitance and a level shift circuit and the amplifier amplifying a signal from a DC componet is realized with less band deterioration and low power consumption.
