Title: Water feeder for washing toilet stool
Inventor: AIDA TOMOKAZU
IPC: E03D1/30
Filed: 1992-12-18
Abstract: PURPOSE:To spare the water by cutting-off or diminishing the supply water before it is necessitated for sealing water, by providing a timing controller which controls the start-timing of discharging water in a washing water supply device, at the time when the water ceases to discharge. CONSTITUTION:When a drain valve B is opened by the movement of a drain- manipulating tool, the water in a larger tank (a) is fed to a toilet stool from the drain valve B through the drain outlet 5. In this time, the water in a smaller tank (b) is discharged from a control hole 4 to remarkably delay the speed of lowering water level of the smaller tank (b), compared with that of the larger tank (a). When the water level of smaller tank (b) is lowered to a specified position, the water supply valve C is opened to start supplying to the tank A. The supply of water into the tank A is delayed by the time when the water level is lowered from the full water level W11 to the specified water level of the smaller tank (b). In this way, useless water can be spared without unnecessary flushing from the water tank to the stool.

The region other than an emitter part and a collector electrode part is removed by etching, and an oxide film 8, having a nitride film 7 on the base layer, is formed on the emitter part and the collector electrode part. The oxide film 8 is exposed by etching back the whole surface, and after the oxide film 8 has been oxidized using buffered HF and the like, it is removed by etching. At this time, the nitride film is left. The polysilicon 9 of the base taking-out electrode part is oxidized, and at the same time, impurities are diffused. The base and the emitter are brought closer with each other, and the mutual positional relation is aligned by the emitter, not by the mask, and a base region is determined. As a result, the area of a transistor can be reduced.

Title: Tab type for semiconductor integrated circuit
Inventor: TAKAHASHI MASATOKI
IPC: H01L21/60
Filed: 1989-12-26
Abstract: PURPOSE:To prevent bonding failure due to irregularity of gaps between leads by comprising a heat insulating zone provided by oxidation of a metal layer in the outer periphery of a device hole that supports leads. CONSTITUTION:A device hole 6 bored at the center of a tape made of copper foil is provided inside with protruding leads 3, and the copper foil outside the device hole 6 is selectively oxidized to form a heat insulating zone 4, which is covered with an Au plating layer 5. Bumps 2 and the inner leads 7 of leads 3 provided in the periphery of an LSI chip 1 are subjected to thermocompression bonding with a bonding tool. Heat supplied from the bonding tool is blocked from dissipation outside the device hole 6 by the heat insulating zone 4 formed around the device hole and is concentrated to leads 3. This design decreases the temperature of the bonding tool and prevents the elongation and deformation of leads, thereby preventing bonding failure due to irregularity of gaps between leads.

Title: Method and device for encoding moving image
Inventor: SEN KOUKIYOKU
IPC: H04N19/60
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve encoding efficiency by independently encoding/decoding the object of any arbitrary rectangular shape and a predictive error expressed in the rectangular shape for the unit of rectangular object. SOLUTION: At an initial mesh generation part 2, a decoded previous frame is divided into regular rectangular initial meshes (or objects). At an object deforming part 4, this mesh is deformed into any arbitrary rectangle. At a motion estimating part 6, the motion of each rectangular object toward the time base is estimated and at a motion compensating and frame predicting part 8, a predictive object is formed from the rectangular object of the previous frame by video warping based on the estimated motion vector. At a predictive error forming part 20, a predictive error signal is generated for the unit of each rectangle. Namely, the predictive error exists inside the arbitrary rectangular object and at an object reconstituting part 22, the predictive error limited to the rectangular shape is transformed to the regular rectangular object in the size of K×K.  At a predictive error encoding part 24, transforming encoding is performed to the error signal limited to the regular rectangular object while using the two-dimensional DCT of K×K.

Abstract: PROBLEM TO BE SOLVED: To eliminate the difficulties of handling due to an excessively long high resistor, for example, by providing means for generating discharge, receiving, detecting and displaying thereby eliminating high resistors and other components for feeding a current from an object to be detected, i.e., an electric apparatus, into a detector. SOLUTION: An electric field 2 generated from an object to be detected, i.e., a high voltage charged part 1, causes discharge in a discharge gap 3 and an electromagnetic wave radiated therefrom is received at a position separated by a specified distance and then it is displayed thus detecting the high voltage charged part 1. In this detector, it is not required to feed a current from the object to be detected, i.e., a high voltage charged part 1, into the detector and to ground the object through a high resistor and thereby the high grounding resistor and other components can be eliminated. Consequently, the difficulties of handling due to an excessively long high resistor, for example, can be eliminated.

Filed: 1989-12-27
Abstract: PURPOSE:To divide a current path in a bending portion into a plurality of the current paths and prevent an electromigration from being generated at a bending point by providing the bending portion of a wide wiring with a number of slits. CONSTITUTION:A plurality of slits 12 are provided in a direction wherein a wiring 11 extends and the slits 12 are also bent according to a bend in the bending portion 13 of the wiring 11. Since the wiring 11 may be separated into a plurality of thin wirings 14, the slits 12 are formed with prescribed widths according to the minimum design rule of a process concerned and may be formed by etching at the same time as the one conducted in the patterning process of the wiring 11. Thus, since the provision of the slits 12 separates the wiring 11 in the bending portion 13 into a plurality of the thin wirings 14, a current 15 flowing in the bending portion 13 is disposed to every thin wiring 14 before the wiring 11 bend. Thus, when a current density is made not larger than a prescribed value, an electromigration phenomenon is not generated.

Title: Electromagnetically operating switch
Inventor: KAWAI HIROKAZU
IPC: H01H33/42
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetically operating switch with reduced chattering due to an impact on contact closing by making flat the attraction characteristics of electromagnetic device for the gap between a movable iron core and a fixed iron core. SOLUTION: (1) On completion of contact closing, a changing contact 42 is made to open. In this state, since a saving resistor 41 is connected to coil 20 in series, the current is reduced and attraction reduces from F1 to F2 (Fig. 7). As for reaction, spring force F3 (Fig. 7) of a spring equipped with a permanent magnet overtakes the attraction F2. Consequently adhesion of the electromagnetic device and the permanent magnet 50 is released.
