Title: Differential amplifier circuit
Inventor: MATSUI TAKAO
IPC: H01L21/8222
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent the gain of a differential amplifier circuit from being changed even when output potential is changed by an input signal by controlling an output from a control means by 1st and 2nd input signals and changing the resistance value of a 1st emitter resistor by the output of the control means. SOLUTION: A resistor bias voltage control circuit 62 can change voltage applied to the N type epitaxial layer of an emitter resistor 54 in accordance with output voltage. Thereby the widening of a depletion layer in the resistor 54 which is fixed in conventional technology is changed. The rate of a change in a resistance value due to the widening of a depletion layer in a load resistor 58 can be set up to the same rate as the rate of a change in the resistance value of the emitter resistor 54. Thereby the gain of the differential amplifier circuit 51 can be fixed without depending upon output voltage. Since the thickness of an air layer formed on a P type semiconductor layer is changed by potential applied to an N type semiconductor layer, the resistance value can be changed in accordance with an input signal.

Title: Automatic temperature control type hot-cool water mixing fuacet
Inventor: HONMA HIDESHIGE
IPC: F16K31/06
Filed: 1989-12-27
Abstract: PURPOSE:To instantaneously obtain a desired temperature of hot water by detecting each temperature of hot water and cool water at the flow path at the upstream side of a mixing chamber, then calculating a hot cool water mix ing ratio, i.e., the opening degree of a control valve based on the detected each temperature and the flow rate. CONSTITUTION:The temperature sensors 1a and 2a and the flow rate sensors 1b and 2b are provided to the flow paths 1 and 2 for the hot water and the cool water respectively. The signals of these sensors are turned into the data via a control part 8. At the same time, the part 8 calculates the opening amounts of control valves 5 and 6 based on the data with the command of the hot water temperature and the flow rate set at a hot water temperature setter 7. The drivers of both valves 5 and 6 are actuated by the output signals so that the desired hot water and cool water volumes are supplied to a mixing chamber 4. Thus a set hot water temperature is instantaneously obtained and furthermore no pressure balance is required between the hot water and the cool water. As a result, an entire mechanism is simplified and miniaturized.
