Title: Hot wire type air flowmeter
Inventor: TSUTSUI MITSUKUNI
IPC: G01F1/68
Filed: 1984-07-26
Abstract: PURPOSE:To improve accuracy of an air flowmeter, by making a bypass, in which an air temperature measuring resistor is arranged, larger than a bypass, in which a heating resistor is arranged, and equalizing the effect of the temperature of a body on both resistors. CONSTITUTION:In a body 50, a main path 51 and a bypass 52 are provided. The bypass 52 is constituted of a straight tube part 53, a tapered part 58, a straight tube part 54, whose diameter is larger than that of the straight tube part 53, and a bent part 55. In the straight tube part 53, a heating resistor 1 is supported by a supporting pin 5. In the straight tube part 54, an air temperature measuring resistor 2 is supported by a supporting pin 6. The resistor 2 is deviated from a part, where the airflow heated by a resistor 1 passes. Since the straight tube part 54 is thicker than the straight tube part 53, the distance between the resistor 1 and the body is made equal to the distance between the resistor 2 and the body. Thus the effect of the body temperature is made equal.

Title: Plasma treating apparatus
Inventor: KOYAMA TOMITAROU
IPC: B29C59/14
Filed: 1981-09-30
Abstract: PURPOSE:To make it possible to carry out the plasma surface treatment of a material to be treated, in a plasma treating apparatus, by providing a metal net like electrode set to potential lower than that of an electrode so as to encircle material to be treated in close relationship to the periphery thereof. CONSTITUTION:When appropriate high frequency voltage is applied between electrodes 4, 5 from a high frequency power source 6, the ions of a gas from a gas source 11 have average voltage and a treating chamber 1 is also charged to certain voltage by the incidence of these ions. At this time, when the potential of a low potential electrode 7 is set to an appropriate value lower than both of the average potential of the gas ions and the charged potential of the treating chamber 1, the gas ions are led to the electrode 7 and impinged on the surface of a long material W through the mesh of the electrode 7 while accerelated. In this case, because the gas ions are uniformly distributed when passed through the mesh of the metal net like electrode 7, surface treatment is uniformly carried out.

Title: Two step fast fourier transform method
Inventor: SUZUKI HIDEO
IPC: G06F17/14
Filed: 1993-06-28
Abstract: PURPOSE:To allow application of a window function, having ripple characteristics in a predetermined pass band and a side lobe level in a folding region, to two step FFT by increasing the degree of freedom in the design of the window function for rough FFT(Fast Fourier Transform method). CONSTITUTION:A window multiplier sets the order of a window function U times as high as the order N of rough FFT and conducts multiplication of a window function having length U.N for an input sample data overlapped at the overlap rate for the order N of rough FFT. An adder 12 divides the multiplication results into U blocks and conducts addition of samples between the blocks thus determining N sample data which are then inputted to a frequency analyzer 4 for rough FFT thus executing N order rough FFT.

Title: Pump device for liquefied gas, and operating method as well as gas supply facility therefor
Inventor: SUZUKI HIDESHI
IPC: F04D15/00
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To realize a pump device for liquefied gas having a long lifetime of bearings and feasibility for a long stable operation. SOLUTION: In this pump device for liquefied gas a rotational frequency is set in low, about 50 min-1, by an inverter 18 when starting a pump 5. A flowmeter 19 judges whether a liquid lifting pipe 2 is filled with liquid or not. When the liquid lifting pipe 2 is judged full of liquid, the rotational frequency of the pump 5 is increased by the inverter 18, for example, up to a high frequency in a range of 5000-8000 min-1. When the pump 5 is stopped the rotational frequency is gradually decreased by the inverter 18. Thereby, the pump device for liquefied gas having a long bearing lifetime and capable of a long-term stable operation can be realized.

With such an arrangement, effect on the electrode section is eased even when the filter layer 7 is pushed down, which makes the thickness of a liquid film stable while permitting supply of a sufficient amount of the liquid to the electrode section. In addition, as a drop in a reaction liquid always occurs from the lower side of the sticky constructions, the electrode section is filled with the reaction liquid gradually from one direction. Thus, there are no bubbles left and no wetting persistent and the like otherwise caused on an electrode, thereby enabling stable measurement.

Title: Timer device utilizing liquid
Inventor: BAN ITSUKI
IPC: G04F3/00
Filed: 1980-11-10
Abstract: PURPOSE:To improve the massproductivity with a simplified construction by generating a signal tone after the elapsing of a specified time employing a cylinder filled with a liquid. CONSTITUTION:When a piston rod 6 is pressed, a piston 2 moves downward against a spring 16 and the viscosity resistance of a liquid 4. At this point, a projection 12 of the rod 6 contacts a sound emitting member 11 to be inverted to generate a mechanical sound thereby confirming that the rod 6 is pressed at a specified distance. The liquid 4 in the cylinder 1 moves with an aid of a film 7 without a rise in the internal pressure. As the external force on the rod 6 is removed, the rod 6 is gradually returned through the combination of the resilience of the spring 16, a small hole 5 and the viscosity resistance of the liquid 4. Then, with the return of the rod 6 at a specified stroke, the projection 13 contacts the sound emitting member 11 to be inverted again. This generates a mechanical sound thereby informing the elapsing of the time.
