Title: Tap water direct applying type bath tub hot water feeding device
Inventor: UNO SHIGEKI
IPC: F24D17/00
Filed: 1990-03-12
Abstract: PURPOSE:To prevent hot water from being leaked out of a communication port even if a small amount of hot water is supplied from a discharging port by a method wherein a communication port communicating with surrounding atmosphere and a hot water feeding port for use in feeding hot water into a bath tub below a valve for shielding a valve seat communicating with an inside part of a hopper are provided. CONSTITUTION:A hot water feeding port 8 is communicated with a hot water feeding port 24 of a bath tub 20 and positioned below a valve 4 located at a position abutting against a valve seat 5 projected from an inner bottom surface of a hopper 3. With such a configuration, at first, hot water fed from a discharging port 2 strikes against the valve 4, passes through a clearance 26 between the valve 4 and the hopper 3 and flows to the hot water feeding port 8. In this case, the hot water feeding port 8 is placed lower than the valve 4, whereby pressures of all hot water are applied to the valve 4, resulting in that even a small amount of hot water pushes down the valve 4 over a spring 22 and enables the valve 4 to be abutted against the valve seat 5 (the right side). Then, the hot water flows through the clearance 26 as indicated by an arrow. Accordingly, it is possible to reduce the amount of hot water discharged from the discharging port of the hopper as low as possible with no leakage.

Title: Microheater, flow pate sensor, and humidity sensor
Inventor: UENISHI MORIMASA
IPC: G01F1/692
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a microheater that, when used with various sensors, can reduce the power consumed, without decreasing their detecting accuracy. SOLUTION: At the rise time of a constant current pulse, a constant current source, which intermittently passes constant current pulses in order to raise the temperature of a resistor to a certain target temperature, supplies a current [current waveform 1] which is given the overshoot A of a current value for a certain time, so that the heat response time τ1 for the resistor temperature to reach the target temperature is reduced, with the result that the current- carrying time required for intermittent drive can be reduced, and since the intermittent drive can be achieved without hindrance, the power consumed can be reduced.  At the same time, since the pulses are not made shorter than the heat response time τ1 and the detecting action of a sensor is performed while it carries the constant current pulses attained by the proper current value, detecting accuracy as a sensor is not deteriorated.

Title: Dynamic logic circuit
Inventor: KAKUMARU NORIKO
IPC: H03K19/096
Filed: 1990-03-14
Abstract: PURPOSE:To prevent the waveform of a clock signal from rounding, signal propagation from delay, and the malfunction of a circuit from occurring in the inside of an LSI, etc., by combining plural clock signals with certain delay quantity, and applying the signals to this dynamic logic circuit. CONSTITUTION:When a clock phi1 goes to an 'L' level, both transistors Q1, Q2 are turned on, and transistors Q3, Q4 are turned off, and output OUT is pre-charged to an 'H' level via turned-on transistors Q1, Q2. When a clock phi2 goes to the 'H' level after the delay of prescribed time td, the transistor Q2 is cut off, while, the transistor Q4 is turned on, therefore, the output OUT goes to the 'H' or 'L' level corresponding to the logic of input IN. In such a manner, since a pre-charge period tpc can be regulated by the delay time td of the clock phi2 for the clock phi1, the wiring of a signal line for the clock for P/D with narrow width in the inside of the LSI is eliminated.

Title: Time display device of electrophoresis display
Inventor: UMEDA KATSUMI
IPC: G09F9/37
Filed: 1978-05-23
Abstract: PURPOSE:To enable the time to be surely known to the user by inverting the display colors of EPID at AM, PM or the set time in the time display device using the display plate (EPID) which makes use of electrophoresis. CONSTITUTION:While time display is being accomplished in a digital time display plate as shown in the figure, the display colors change with AM and PM. For example, in the case of AM, the display part 10 is made black and the background and the display segment part 9 of OFF are made white. When it becomes PM, the polarity of the display color assignment signal of a display plate driving circuit inverts and the dispaly colors invert, thus distinctly indicating the difference of AM and PM. If such a method of driving the EPID is employed, the cumulation time of the ON and OFF states of the segments and background parts of EPID becomes equal, and this makes contribution to the long-term stability of the dispersion system.

Title: Light-emitting element module
Inventor: SHIOZAKI MANABU
IPC: H01S5/00
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting element module having good temperature stability. SOLUTION: Light with a given wavelength is emitted though inverted population at an active region 13 in a semiconductor light-emitting element 10 fed with a current. A light with a given wavelength repeats reciprocations between the reflecting surface of the semiconductor light-emitting element 10 and a diffraction grating 23 of an optical fiber 20, and light amplification is carried out by induced emission. Then, laser oscillation is held and a part of the laser beam is transmitted through a diffraction grating 23 and is output.  Since the full width at half maximum of a reflecting spectrum of the diffraction grating 23 is smaller than the space between longitudinal-mode wavelengths which is determined on the basis of an optical length between the reflecting surface 17 of the semiconductor light-emitting element 10 and the central position of the deffraction grating 23 of the optical wave guide 20, the temperature region of stable oscillation is wide, and the light-emitting element module has good temperature stability.
