Title: Resonance prevention system for system
Inventor: TACHIBANA IKUYA
IPC: F16F15/00
Filed: 1984-11-29
Abstract: PURPOSE:To improve the vibration-resisting quality of electronic equipment by changing the spring constant of a damping device for adjusting the resonance point and preventing the occurrence of acceleration over a predetermined level. CONSTITUTION:In a normal vibrating condition, a special damping device 3 and a general damping device 4 work concurrently and the characteristics of curves 7 are given with a resonance point W2 due to a synthetic spring constant. When a vibratory frequency nears the resonance point W2, generated acceleration increases. As soon as it has exceeded a predetermined acceleration level 9, the damping member of the foregoing damping device 3 gives a slip and this device becomes free. Consequently, the said spring constant is changed over, giving the characteristics of curves 6 with a resonance point W1, and generated acceleration rapidly gives a drop. The vibration-resisting quality of electronic equipment is thereby improved.

Abstract: PURPOSE:To eliminate cavities generating in the filling insulator by making V-grooves as element-isolating grooves by a method wherein a resist adhered on a substrate is opened in taper form, and a V-groove is formed in the substrate by anisotropic etching with the resist as the mask. CONSTITUTION:A GaAs layer 2, a P-GaAs layer 3, an N-AlGaAs layer 4, and an N<+>-GaAs layer 5 are epitaxially grown on the GaAs substrate 1 of the title device; thereafter, the whole substrate is coated with a resist 9, and a V-groove 10 forming region is opened by the process of photolithography. At this time, the aperture edge of the resist 9 is tapered by selecting the conditions of exposure. Next, the V-groove 10 reaching the substrate 1 is formed by ion milling with the resist 9 as the mask. After removal of this resist 9, the whole substrate is coated with an insulation film 7 by chemical vapor phase growth by filling the V-groove 10. Further, the V-groove 10 coated with the film 7 is used as the element-isolating groove by etching the film 7 and the resist 11 coating thereon until the layer 5 is exposed.

Abstract: PROBLEM TO BE SOLVED: To reduce electric power consumption and to enable higher fineness by providing a display panel drive assembly with a capacitor for voltage superposition, adding power source supply and the accumulated voltage of the capacitor for voltage superposition and selectively supplying the voltage. SOLUTION: When the transition from the off state to the on state of an FETQ1 is caused by the control signal from a control circuit 3 and the transition from the on state to the off state of an FETQ2 is caused, the voltage level V/2 accumulated in the capacitor C1 for voltage superposition is added to the power supply voltage level V/2 of a constant voltage source Vd and the voltage level of a data voltage input terminal P1 attains a V. The voltage level of the output terminal PZi (i=1 to n) of the driver IC1 is changed from V/2 to the V. At this time, the charges accumulated in the capacitor C1 for voltage superposition are supplied through FETQPi (i=1 to n) and the charges are charged in the respective column electrodes. At the time of writing pixel data, the driving voltage of the capacitive column electrodes is approximately halved to drive the electrodes in two stages.

Title: Selective diffusion of boron
Inventor: MEGURO KEN
IPC: H01L21/22
Filed: 1987-10-07
Abstract: PURPOSE:To prevent a silicon oxide film from being contaminated by boron by forming the silicon oxide film and a silicon nitride film over the entire surface of a semiconductor followed by the formation of windows through both films, introducing an impurity into the semiconductor surface at a high concentration and a shallow level through those windows, removing the silicon nitride film, and deeply diffusing the impurity so introduced into the semiconductor. CONSTITUTION:A double layered film of a silicon oxide film 10 and a silicon nitride film 20 are first formed on the surface of a semiconductor 1 in the process of formation of a masking film. Thereupon, the silicon nitride film 20 prevents boron from invading the silicon oxide film 10, and simultaneously boron 6a is introduced into the semiconductor surface from a window 5 formed therein at a location where an impurity is selectively diffused. Then, the silicon nitride film 20 is removed from the upper part of the silicon oxide film 10. After the removal of the silicon nitride film 20, the boron introduced into the semiconductor surface at the desired location of the same is deeply and selectively diffused into the semiconductor. Hereby, the silicon oxide film is securely protected by the silicon nitride film against the invasion of the boron upon the introduction of the boron into the semiconductor surface. The semiconductor surface after the removal of the silicon nitride film is covered with the clean silicon oxide film.

Title: Variable differential pressure generator
Inventor: NAGAOKA YUKIO
IPC: F16K15/16
Filed: 1990-09-21
Abstract: PURPOSE:To provide large differential pressure with simple construction and small flow rate by providing a partially fixed spring plate, an opening section formed by the bending of the spring plate to increase the opening along with the increase of fluid pressure. CONSTITUTION:A spring plate 14 together with a stopper 15 has one end fixed to a casing 13 having an inlet 11 and outlet 12, and in the absence of flow the spring plate 14 closes the inlet 11. The spring plate 14 is surrounded by an opening limiting body 16 for limiting the opening area in the early displacement of the spring plate 14. In the presence of flow, the spring plate 14 is bent by the fluid pressure to be separated from the inlet 11. Since the openings 11a of the opening limiting body 16 and spring plate 14 are small in the small flow rate, resistance against the flow is large, and generated differential pressure is large. The openings 11a are enlarged in the large flow rate to release the opening from the limitation of the opening limiting body 16, reduce the fluid resistance and the increase of rate of differential pressure generation and thereby provide a differential pressure property as shown by A.

Title: Locking method of nut to bolt and locking device for bolt/ nut
Inventor: SHIMIZU MASAOMI
IPC: F16B39/34

Abstract: PROBLEM TO BE SOLVED: To perform simple and sure locking by screwing a fastening ring capable of being expanded/contracted to a bolt, screwing a nut to the bolt, thereafter inserting the fastening ring into the nut in a press contact manner, and generating frictional force between the bolt and the fastening ring and between the nut and the fastening ring. SOLUTION: A fastening ring 2 capable of being a little expanded/contracted because of having a slit 23 is mounted on a bolt 3, screwed in until it is contacted with a member T to be fastened, and thereafter a nut 1 is screwed in. Even when the edge 13 of the spread hole 12 of the nut 1 is brought in contact with the fastening ring 2, because the fastening ring 2 is rounded at the edge, the fastening ring 2 is smoothly put in the spread hole 12 and inserted gradually into the spread hole 12 in a press contact manner by further rotationally moving the nut 1. By contacting the nut 1 with the member T to be fastened, the screwing-in is completed, and strong frictional force is applied between the nut 1 and the fastening ring 2 and between the fastening ring 2 and the bolt 3. Consequently, even if repeated stress or large impact force is applied to them, looseness is not generated.

Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To obtain fatty fishes having film flesh, and good luster and color by regulating water temperature and sunshine to control spawning in addition to the conventional fish farming in which raising and breeding fishes are performed. SOLUTION: The purpose of this invention is achieved by increasing the appetite of fishes and promoting their growth by cooling the temperature of to seawater river water or well water in a nursery or a fish preserve, indoors or outdoors. 16-12 deg.C in summer and heating it up to 12-16 deg.C in winter.
