Title: Feed water tank
Inventor: HIRAYAMA KENICHI
IPC: F24F6/00
Filed: 1985-10-11
Abstract: PURPOSE:To obtain an apparatus having an increased capacity of overflowing without increasing the size of a feed water tank, with separating a water chamber from an overflow water chamber by an overflow water weir, increasing the total length of said weir by forming the cross section of said weir into a zigzag-shape. CONSTITUTION:An overflow water chamber 22 is separated from a water chamber 24 by an overflow water weir 21 having a cross section formed into a zigzag-like shape and has an overflow water port 23 at the bottom thereof. When an electromagnetic valve is caused to be opened continuously due to the trouble of said valve or a float switch 5, water level rises with the result that the water overflows the overflow weir 21 and flows into the overflow water chamber 22 to be discharged from the overflow water port 23 to a drain pan etc. through an overflow pipe. The capacity of overflowing is directly proportional to the total length of the overflow water weir 21. The overflow water weir 21 having a zigzag-shape can provide a longer total length; as a result, the capacity of overflowing can be increased without increasing the volume of a feed water tank.

Title: Device for grading sound signal and method therefor
IPC: H03M1/58
Filed: 1992-08-26
Abstract: PURPOSE: To obtain a volume control device capable of smoothly and accurately increasing/decreasing a volume, in response to time transition by making the increasing/decreasing of a graded volume correspond to the logarithmic property of a sensed sound. CONSTITUTION: A sound processing is performed using the digital signal processor(DSP) 90 of a sound subsystem of a computer. In a digital audio reproduction, a code by which the host computer controls the DSP 90 and a digital audio sample from its memory or disk are taken out and transferred to a shared memory 80 via an input/output bus 10. The DSP 90 takes out the sample under the control of a code and converts this into an integral value showing a logarithmically-graded value under the control of the code, and supplies this value to a sample memory 130. Then, the DSP 90 activates a DAC 140 for converting the digitalized sample into a sound signal, takes out the digital sample from a memory 130, analog-converts this, and supplies the analog signal to an analog output part 160. The signal reaches ears from an output connector via a speaker or a headphone.

IPC: H01L21/304
Filed: 1993-09-13
Abstract: PURPOSE:To reduce hydration, surface roughing, metal adsorption and the like on the surface of a workpiece to be treated by providing a negative potential to the workpiece to be treated with respect to the potential of an aqueous solution when surface treatment is performed. CONSTITUTION:A semiconductor substrate 1 serving as a workpiece to be treated and a standard electrode 3 are emmersed in an aqueous solution 11 filled in a liquid tank 9. The semiconductor substrate 1 is housed and supported in a cassette 5 and connected to the negative electrode of a power source 7. The positive electrode of the power source 7 is connected to the standard electrode 3. By impressing a cathode bias on the semiconductor substrate 1, anions of negative charge in the aqueous solution 11 repulse from the negative-biased semiconductor substrate 1 and a probability of approaching the semiconductor substrate 1 surface greatly diminishes. Consequently, a reaction intermediate which will serve as a chemical, reaction medium on the semiconductor substrate 1 surface becomes difficult to form with anions, arresting the generation of hydration, surface roughing, and metal adsoprtion and lessening the density of defects on the semiconductor substrate surface and inside.

Title: Reference voltage generating circuit
Inventor: TSUKAMOTO KAZUO
IPC: G05F3/24
Filed: 1988-09-12
Abstract: PURPOSE:To set the temperature coefficient at zero and to easily produce the reference voltage of high accuracy on a chip of an integrated circuit by using the sum of the junction voltage of a junction diode and the difference of each junction voltage obtained when such currents having different current densities and a fixed ratio between them are supplied to two junction diodes. CONSTITUTION:The difference of the junction voltage obtained when such current having different current densities and a fixed ratio between them are supplied to the 1st and 2nd junction diodes D1 and D2 has a positive temperature coefficient. While the junction voltage of the diode D2 has a negative temperature coefficient. The reference voltage VREF is obtained by adding the both- terminal voltage of a 2nd resistor R2 which is obtained from the difference voltage (both-terminal voltage of a 1st resistor R1) between both diodes D1 and D2 in response to the ratio of each resistor to the junction voltage of the diode D2. Thus the temperature coefficient can be set at zero and the reference voltage of high accuracy is easily obtained.

Filed: 1991-09-09
Abstract: PURPOSE:To attain automatic setting to a proper integral time in response to a power supply frequency with simple configuration by selecting one of two kinds of integration times in response to a power supply frequency so as to integrate a power signal for the integral time. CONSTITUTION:Analog switches 2, 9 are driven switchingly complementarity by a CPU 5 and a measurement signal fed to an input terminal 1 is inputted to an integration type A/D converter 4 via a differential amplifier 3 by closing the switch 2. Moreover, with the analog switch 9 closed, a voltage of a commercial power supply 6 is inputted to the integration type A/D converter 4. The CPU 5 turns off the switch 2 at first and turns on the switch 9 to apply a power supply signal to the integration type A/D converter 4. The CPU 5 in this state selects an integration time of the A/D converter 4 and compares the result of integration of two kinds and selects an integration time offering less output fluctuation. Then the CPU 5 turns on the switch 2 and turns off the switch 9 to apply a measurement signal to the A/D converter 4.

Title: Operation system of switchgear
Inventor: NAKAHATA MINORU
IPC: H01H33/42
Filed: 1989-09-01
Abstract: PURPOSE:To obtain sufficiently sensitive operation even with a short displacement by installing a piezoelectric device which comes into contact with a latching means under stopped condition of the latching means and releases the stopped condition of the latching means when electric voltage is applied to the device to displace and pull out the device. CONSTITUTION:A piezoelectric device 28 is set to come into contact with an arm part 25a of an input latch 25 under stopped condition. Another piezoelectric device 29 is set to contact with an arm part 22a of a trigger 22 under stopped condition. When electric voltage is applied to the piezoelectric devices 28, 29, they displace at once and they have a character that the shorter their displacement is, the higher the outlet becomes. Owing to this the maximum output of piezoelectric devices 28, 29 is obtained at the initial stage of operation of releasing the stopping condition of the latching means 20. Also, since the output becomes lower as the displacement becomes larger, the strength of the latching means 20 may be enough if it is durable for releasing the stopping condition and the necessary strength may be low.

Title: Duty ratio deciding circuit and method for deciding duty rato
Inventor: UMETSU CHIKO
IPC: G01D5/245
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To decide a duty ratio with a simple circuit configuration. SOLUTION: An up-down counter 2 starts to up and down count in response to a rise detection signal and a fall detection signal of a pulse from an edge detector 1. The detector 1 outputs a preset signal for designating an input of a start value of a count to the counter 2 immediately before the detector 1 outputs the rise detection signal. A CPU 5 sets a start value of a count to a register 6 so that a counted value becomes '0' at the time of ending one period of the pulse of a reference duty ratio. The counter 2 inputs a start value from the register 6 in response to a preset signal from the detector 1. An up- down counter status flag register 3 outputs '1' when the counted value is minus and outputs '0' when the counted value is plus.
