Title: Preparation of case or the like
Inventor: KOBAYASHI KUNIO
IPC: B29C53/00
Filed: 1979-01-31
Abstract: PURPOSE: To simplify manufacture and to increase form retention and strength respectively of cases or the like made from thermoplastic synthetic resin sheets by preliminarily attaching soft plastic synthetic resin strigns with the aid of high- frequency melt-sticking to the portions on a cut material sheet for the said case predetermined to be edges of completed case body and lid.  
     CONSTITUTION: For example, after cutting out polyvinyl chloride sheets having nearly equal-sizes and different colors a lid part 2 of the base sheet is laid there on. High frequency voltage is then applied to said lapping part with an upper electrode provided with large and small edges respectively at the outer and the inner edges, and the polyvinyl chloride sheet and base sheet are fused and cut with the outer edge, while solely the base sheet is fused and stuck to the edge the lid part 2 with the inner edge. After tearing the inside portion of the sheet off along the fused contour of the sheet, synthetic resin strings 4 are melt-stuck along edges of the lid part 2. Case body part 1 and gusset parts 3, 3' are ordinarily cut out, then a poly vinyl chloride string 5 is laid between the edge line of the case body part 1, the case body part 1 and the gusset parts 3, 3' and is stuck thereto by the high-frequency melt-sticking with the upper electrode.

Title: Data processor containing cache and its data access method
Inventor: NAKAGAWA HIROMASA
IPC: G06F12/08
Filed: 1990-01-18
Abstract: PURPOSE:To shorten a bus cycle by attaining a constitution where a CPU and a cache read the data to receive an access out of those data read out of a memory and then the cache reads the remaining data and also inhibits the CPU from having an access to the data. CONSTITUTION:The data on an address designated by a CPU 1 are first read simultaneously and in parallel into the CPU 1 and a cache 2. The remaining plural data are read into the cache 2 after the CPU 1 is through with its read access. The CPU 1 does not assert the new address and bus control signals, etc. However the internal processing, e.g., the pipeline processing, etc., of the CPU 1 is carried on. Then a circuit, etc., that can perform the read accesses in the same cycle regardless of the presence or absence of a reread request is added into the CPU 1. In such a constitution, a bus cycle is shortened.

IPC: H01Q13/22
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To improve the radiation gain of a slot antenna and also to obtain the directivity of broad side radiation. SOLUTION: Slots 113 are formed on one metal plane 111 of a parallel plate waveguide 101 that constitutes a slot antenna 110, and also recessed grooves 114 are formed on the other metal plane 112 of the waveguide which faces the slots 113. The widths, depths and positions of the slots 113 and the grooves 114 are set so that radio waves that undergo waveguiding in the waveguide 101 can be the same reflected amount in the slots and grooves respectively. Radio waves that are reflected by the slots 113 are become reverse phase to radio waves reflected against the grooves 114, reflected waves at the slots 113 are cancelled, the reflected quantity as a whole is reduced, radiation quantity from the slots 113 is increased, and the radiation gain of the antenna 110 is improved.  Also, it is possible to arbitrarily set slot intervals, even with desired radiation gain secured and to get the directivity of broad side radiation.

Abstract: PURPOSE:To reduce a change in melt viscosity and to stably obtain a light- colored extrudate by adjusting the water content of a polyarylene sulfide composition to a specific range and extruding said composition in a molten state at specific temp. CONSTITUTION:The proper water content of a polyarylene sulfide composition is 0.1-1.5wt.% and, when the water content is too little, effect is low and, when the water content is too much, a foaming phenomenon is generated. In order to adjust the water content of the composition, a method of uniformly blending a definite amount of water with the composition by a Henschel mixer is convenient. As an extruder, either one of a vent type one and a non-vent type one may be used. It is pref. that polyarylene sulfuide has a high m.p. and the melt extrusion temp. thereof is 290-370 deg.C. This method is especially effective for the preparation of a pellet due to extrusion.

Title: Method for continuously casting thin cast slab
Inventor: FURUKAWA MASAZO
IPC: B22D11/20
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To prevent the detachment of solidified shell at the initial stage of a casting and to restrain the defective part at the initial stage of the casting to the min. limit while shifting to an operation holding the thickness of a cast slab to the constant by starting the casting under a constant rolling force in a twin roll type continuous casting method and shifting to a constant gap control on the way of the casting. SOLUTION: The rolls are brought into contact with mutually the other roll at the constant rolling force until the molten metal surface level in a molten metal pool part reaches a target stationary level. Range of the described rolling force is 2-30kgf/ mm per the unit length of a cast slab width. When the molten metal surface reaches a prescribed level, the constant rolling force control is changed over to the constant gap control. The stationary morten metal surface level is the molten metal surface level, in which the contacting length between the molten metal and the rolls are equalized in the upper and lower rolls. Then, even in the case of changing over to the constant gap control, the roll gap is scarcely changed and press-sticking force is secured, and the separation of the solidified shell is not developed.  Further, since the thermal deformation on the peripheral surface of the roll is converged to a fixed value, the variation of the thin slag thickness is not developed and the stable thickness is obtd.

Abstract: PURPOSE:To enable positive detection of an aircraft located on a ground passage alone, by receiving a reflected pulse from an aircraft and noises thereof with an ultrasonic transmitter/receiver arranged near the passage. CONSTITUTION:First, when an ultrasonic pulse is transmitted from an ultrasonic transmitter/receiver 7, a reflected pulse from an aircraft 5 is received with the transmitter/receiver 7 delayed by a specified time and amplified with an amplification circuit 82 when the aircraft 5 is present within the radiation range thereof.

An output of the circuit 84 forms a signal containing not only reflected pulse but also noise. Thereafter, the detection output is judged as to the level with a level judging circuit 85 to obtain a detection output P0 containing reflected pulse and noise. When the level of the noise is below a specified value, a pulse detection output is obtained correspondingly to the reflected pulse.

IPC: H01L21/3205
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To surely prevent the occurrence of a short circuit between a gate electrode and upper-layer wiring. SOLUTION: At forming of a contact hole, a BPSG film which becomes an interlayer insulating film is formed after a sacrificial film, namely a silicon nitride film 7, which can secure the etching selection ratio with respect to silicon oxide films 4, 5, and 6 is formed on the upper surface of a sample, and then the occurrence of a short circuit between a gate electrode and upper-layer wiring is surely prevented by removing the BPSG film through flattening. In conventional examples, a state occurs such that even the silicon oxide films which protect the gate electrode is etched off at etching of the BPSG film, because the etching selection ratio with respect to the silicon oxide films is hard to be secured, and consequently, short circuit between the gate electrode and upper-layer wiring is likely to occur.  However, since the sacrificial film is interposed between the BPSG film and silicon oxide films, the occurrence of the overetching can be prevented.
