Title: Pressure stop valve
Inventor: NAKAMURA KAZUHARU
IPC: F16K15/02
Filed: 1983-08-26
Abstract: PURPOSE:To reduce pressure loss of a valve portion by providing a valve portion comprising a valve seat formed on the end portion of a pipeline and a diaphragm disposed opposite to the valve seat in such a manner as to face to the atmospheric pressure on one side thereof so that the diaphragm can be easily moved by usual supply pressure of water supply. CONSTITUTION:A valve seat 2 is formed on the end portion of a pipeline 1, and a diaphragm 3 is disposed opposite to the valve seat 2 in such a manner as to face to the atmospheric pressure on one side thereof. The diaphragm 3 is urged toward the valve seat 2 through a push rod 7 and a holding plate 6 by a push spring 5. Another pipeline 4 is connected to the outer periphery of the valve seat 2. In this arrangement, water supply pressure is applied to the diaphragm 3 from either of pipelines 1, 4 so that the diaphragm 3 is moved until the holding plate 6 is brought into contact with a stopper 8. Then, the valve seat 2 and the diaphragm 3 are separated from each other to circulate water between the pipelines 1, 4. Thus, the diaphragm 3 can be easily moved to reduce pressure loss of a valve portion.

Title: Method of fabricating fine semiconductor structure
Inventor: KAKAZU MAKOTO
IPC: H01S5/00
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method of fabricating a fine structure with high accuracy so as to have the same size by allowing the tip of a probe to approach the surface of a selection film only by a predetermined distance on an atom unit basis and selectively etching the selection film by flowing a tunnel current between a semiconductor substrate and the probe. SOLUTION: An oxide film 2 on the surface of a GaAs substrate 1 exposed in the atmosphere is heated and removed in vacuum, thus exposing the surface of the GaAs substrate 1. A GaN film 4a is deposited on the exposed surface of the GaAs substrate 1 and a probe 11 is brought close to the surface of the GaN film 4a at a distance of 1nm. A switch 13 is changed to increase a tunnel current between the probe 11 and the GaAs substrate 1 and partial etching is performed to the GaN film 4a with the energy on an atom unit basis. Consequently, the GaN film 4a is selectively patterned. Thus, the fine structure can be fabricated so as to have the same size with high accuracy.

Title: Thin-film transistor circuit and its driving method
Inventor: OGAWA KUNI
IPC: H04N5/335
Filed: 1987-06-24
Abstract: PURPOSE: To obtain a stable electric characteristic over a long period, by driving thin-film transistors by using a waveform composed of symmetrical potential of positive and negative as gate voltages.  
     CONSTITUTION: A waveform composed of symmetrical potential of positive and negative is used as gate voltages and all thin-film transistors T 21 ∼T 2n  and Tk 1 ∼Tk 1  are driven. Therefore, continuous application of potential of the same direction for a long period to a specific thin-film transistor can be avoided. Electric charges of carriers, moved ions, etc., caught into a semiconductor, insulating body, and their boundary by means of a positive voltage (or negative voltage) are changed by a negative voltage (or positive voltage) in such a way that the carriers are started from the catching level and the ions return to their original locations. Accordingly, the variation of the drain currents of the transistors T 21 ∼T 2n  and Tk 1 ∼Tk 1  is reduced and driving circuits of the transistors can make normal operations successively even when they are used continuously for a long period.

Title: Cooling device for construction machine
Inventor: KATO AKIRA
IPC: F01M5/00
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain an efficient cooling device by arranging an intercooler and a radiator for an airconditioner so as to put one on top of the other at the front face of the radiator and juxtaposing an oil cooler of which the ventilation area and the thickness are decided to nearly uniformize the entire thickness. SOLUTION: An intercooler 15 is stacked in front of a radiator 13 and arranged in parallel with an oil cooler 21. Further, a condenser 16 for an airconditioner is put in piles. The thickness L2' of the oil cooler 21 is made thicker as compared with conventional oil coolers, and the ventilation area thereof is lessened to have the same cooling effect. In this way, the entire thickness of the cooling device is nearly uniformized and made thin but nevertheless the ventilation efficiency can be increased. Further, the oil cooler 21 can be rotatably supported by a swing-out mechanism. Accordingly, the cooling effect becomes efficient and hence, the cooling device can be miniaturized and mounted on a small-sized machine. Moreover, the radiator and the oil cooler can be easily cleaned.

Title: Weighting electrode for surface acoustic wave filter
Inventor: YAMADA YOSHIHIRO
IPC: H03H9/145
Filed: 1991-06-27
Abstract: PURPOSE:To realize the weighting electrode having no design limit due to a quantization error and with less deterioration due to a diffraction effect by devising the exciting intensity of a surface acoustic wave to be proportional to a difference of a cross width while the cross width is constant independently of location. CONSTITUTION:An electrode finger 11 at an odd number position is connected to a bus electrode 14 and an electrode finger 12 is connected to a bus electrode 15. Moreover, an electrode finger 13 at an even number position is connected to a bus electrode 16. Then a sum' (W1+W2) of a cross width W1 between the electrode fingers 11,13 and a cross width W2 between the electrode fingers 12, 13 is constant independently of location. Furthermore, a voltage V1 applied between the bus electrodes 14, 16 and a voltage V2 applied between the bus electrodes 16, 15 are made identical to allow the intensity of a surface acoustic wave excited from the cross widths W1, W2 is proportional to (W1-W2). As a result, since the sum of the two cross widths is always constant in the weighting electrode in the surface acoustic wave filter, the filter is immune to the diffraction effect and a design limit in the quantization error is not caused but the electrode is applied freely.
