Abstract: PURPOSE:To provide a fixed hysteresis width to be set optionally and to improve the sensitivity of output changeover with respect to a change in an input voltage by varying a current of a constant current source and a resistance of a resistor coupled with an emitter of each input transistor(TR). CONSTITUTION:Two input TRs 6, 7 to the bases of which a compared voltage is applied, two resistors 14, 15 connecting in series between the emitters, a 2nd constant current source 8 connecting to a connecting point of the two resistors 14, 15 and a 1st constant current source 4 connecting to the emitter of the input TR 6 via a diode 5 are provided to the comparator. Moreover, base voltages of the TRs 6, 7 from a connecting pint between a diode 6 and a 1st constant current source 4 are compared and a current of the 1st constant current source 4 is extracted by a switching TR 3. Then the switching TR 3 is turned on and off and a difference of the voltages caused at the two resistors 14, 15 is taken as a hysteresis width. Thus, the fixed hysteresis width set optionally is provided and the changeover of the output with respect to a change in the input voltage is implemented with high sensitivity.

Title: Viscous fluid coupling of temperature responsive type
Inventor: YAMAGUCHI YUUJI
IPC: F16D35/02
Filed: 1982-07-12
Abstract: PURPOSE:To prevent an overshoothing phenomenon of fuid when an engine is started, by transferring the viscous fluid in a working chamber to a storing chamber when a speed of the engine reaches a level below the idle speed at stopping of the engine and blocking a flow of the viscous fluid in the direction reverse to the above described transfer after the engine is stopped. CONSTITUTION:When an internal-combustion engine is operated, a storing chamber 22 and a working chamber 21 are communicated by the opening of a ball check valve mechanism 30 due to centrifugal force resulting from rotation of a cover 14 and the opening action of a return hole 28 in a valve plate 26 through a bimetal 27. A driven side is rotated in proportion to the amount of fluid flowing into said working chamber 21. If the engine is stopped under such operative condition, first when a speed of the engine is decreased to a level below the idle speed, the valve mechanism 30 is closed, and fluid in the working chamber 21, with a small amount of the fluid remaining in said chamber 21, is returned to the storing chamber 22 through a ball check valve mechanism 40 by the pumping action with a pump protrusion P, thereafter when the engine is stopped, the both chambers 21, 22 are perfectly disconnected by the closing of the valve mechanism 40.

Abstract: PURPOSE:To make it possible to measure the upper-limit value and the lower- limit value accurately based on the load signal by comparing a peak value and a valley value which are updated and read at every sampling time with the data at the previous sampling time. CONSTITUTION:The load signal from a load detector is amplified in a load amplifier 4. The signal is inputted into a peak hold circuit 6, a valley hold circuit 7 and a multiplexer 9. In the circuits 6 and 7, the peak value and the valley value until the sampling time of the load value which is changing from time to time are stored. The stored values are read with a CPU 11 together with the direct value from the amplifier 4 at every sampling time through the multiplexer 9. The CPU 11 resets the circuits 6 and 7 and processes the data. Namely, the peak value of the circuit 6, which is read with the multiplexer 9 that is set at the peak hold, is compared with the direct value, and the maximum value of the data is obtained. The value is measured as the upper-limit load. The lower limit value is measured by the same way. Since the change in load is measured in this way, the accurate measurement can be performed.

Title: Rice cooker
Inventor: MIYAUCHI TAKAHIRO
IPC: A47J27/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress steam generation and to make cooked rice delicious by heating the water in an inner pan to a boiling point or below and fluidizing the water. SOLUTION: Rice cooking is started by setting the inner pan 2 containing rice and water into a rice cooker main body and driving an inner pan heating means 5 to heat the inner pan 2. The temperature in the inner pan 2 is detected by an inner pan heating means 4 and is sent to a heating control means. As a result, the inner pan heating means 5 is so controlled that the temperature in the inner pan 2 attains the boiling point of the water or below. Further, a water flow generating means 3 is driven to fluidize the water while the water still exists during rice cooking. As a result, the generation of the steam is suppressed and the heat transfer to the rice is accelerated by the water flow. Accordingly, the heat quantity for rice cooking can be sufficiently imparted to the rice and the delicious cooked rice can be obtained.
