Title: Receiver circuit with temperature compensating function
Inventor: HIRAYAMA YOSHIHIKO
IPC: H03B5/08
Filed: 1978-11-08
Abstract: PURPOSE: To prevent tuning-out by automatically compensating a local oscillation frequency by making a temperature sensing element detect a temperature where the cancellation of a temperature coefficient is disabled.  
     CONSTITUTION: To the base of transistor in mixing and local-oscillation circuit 13 with a temperature compensating function, a bias circuit composed of resistance R 1  and thermistor 7 is connected. Transistor 8 is cut off nearly at the normal temperature. As a result, a voltage applied to a varactor diode is equal to V cc . At a temperature where temperature coefficients of the oscillation circuit, coil and capacitor can not be canceled, the resistance value of thermistor 7 falls and transistor 8 starts conducting. As a result, the voltage applied to varactor diode 9 drops and electrostatic capacity increases, thereby correcting the oscillation frequency. At this time, the increase rate of the electrostatic capacity is variable with resistance R 2 .

Title: Optical pressure sensor
Inventor: TSUCHIYA JUN
IPC: G01L9/00
Filed: 1986-06-13
Abstract: PURPOSE:To increase a detecting accuracy by a simple construction by providing an optical attenuator composed of an elastomer wherein a coloring matter is dispersed in a light path so that the elastomer can detect a pressure change as a variation in a transmitted light quantity. CONSTITUTION:A light beam from a light source 3 is incident upon an optical attenuator 1. When a pressure is not applied to the optical attenuator 1, the incident light beam is dispersed or absorbed by a coloring matter in an elastomer and emitted with a prescribed light quantity reduced to reach a light quantity measuring instrument 4, wherein the light quantity is measured. Then, when the pressure is applied to the optical attenuator 1, this is deformed, for example, as shown in broken lines in the accompanying drawing, and an optical path length through the optical attenuator 1 changes. The light beam with the light quantity reduced or increased by the one corresponding to changes in the optical path length is emitted and reaches the light quantity measuring instrument 4. By forming a quantity detecting line in advance in the light quantity measuring instrument 4, a pressure change can be detected from the reduced or increased light quantity.

IPC: H02J7/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a life determination method by which the life of a lead-acid battery can be determined with higher precision in a short time. SOLUTION: For determining lifetime, a lead-acid battery is periodically discharged in a short time high rate constant current, terminal voltages before and after every discharge image are measured, and the lifetime is determined utilizing a difference voltage between the measured terminal voltages. When the difference voltage of the terminal voltages before and after every discharge time is equal to a predetermined reference difference voltage or more, it is determined (step ST4) as a battery life. When the terminal voltage at the discharge termination time when the number of times reaches a predetermined number of discharge times is equal to a predetermined reference voltage or less, it is determined (step ST5) that the battery lifetime isover, even if the every time difference voltage is smaller than the reference difference voltage.  When the difference voltage of the terminal voltage at the first discharge termination time and the terminal voltage at the discharge termination time when the number of times reaches the predetermined number of discharge times is equal to an upper limit reference voltage or more, it is determined (step 6) that the battery lifetime is over.
