Title: Converter
Inventor: ROBAATO UEIN REIBII
IPC: G01R25/00
Filed: 1991-03-06
Abstract: PURPOSE:To provide a phase/angle measurement method which can obtain high measurement accuracy even when accuracy of a mechanical part of a rotor system or the like is not very high. CONSTITUTION:Each rotor generates two periodic signals of the same cycle (wherein P phenomena occur during a cycle in one signal while Q phenomena occur during a cycle in the other signal). Reference points are determined respectively in cycles of the respective periodic signals, relative timing of phenomenon occurrence with respect to the reference point is obtained to calculate the average, and the average is assumed to be one virtual occurrence timing of the phenomenon. From difference in virtual phenomena occurrence timing of the two periodic signals, phase difference between the periodic signals and, furthermore, difference in angles between the rotors can be calculated.

Filed: 1986-03-26
Abstract: PURPOSE:To judge a fault of an apparatus to be protected by counting the operational times of a plurality of protectors, discriminating operating protectors from other non-operating ones, and indicating the former. CONSTITUTION:The operating time of a switching contact of an overload protecting relay 16 amounts to several minutes, and that of a switching contact of an overload protecting relay 17 within the compressor is in the range of 10-20min. A high-pressure switch 15 is restored substantially instantaneously to a condition at the operation stopping time of the compressor.

Abstract: PURPOSE:To reduce a stray capacity between a semiconductor chip and a lead, to enhance a signal transmission speed and to reduce an electrical noise by forming a stepped structure in a manner that an interval between the semiconductor chip on the side of an outer lead from a part bonded to an insulating film and an inner lead is wider than an interval between the part bonded to the insulating film and the semiconductor chip. CONSTITUTION:At a lead frame, 20 inner leads 3A1 for signal use and two inner leads 3A2 for common use are installed. Regarding inner leads 3A (the inner leads 3A1 for signal use and the inner leads 3A2 for common use), a stepped structure is formed in such a way that an interval between a part on the side of outer leads 3B from a part bonded to their insulating film (insulator) 4 and a semiconductor chip 1 is wider than an interval between the part bonded to the insulating film 4 and the semiconductor chip 1. When the inner leads 3A are formed as the stepped structure in this manner, a stray capacity between the semiconductor chip and the leads is made small as compared with that of conventional structures; accordingly, a signal transmission speed can be enhanced and an electrical noise can be reduced.

Patent JP-H10260896-A (JP)
Title: Semiconductor device
Inventor: WATABE TAKAO
IPC: G06F12/04
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To make a semiconductor device possible to deal with larger program without increasing the chip area, by converting data in a chip, storing compressed data in a memory, extending it at the time of loading it in a cache memory and using it by a processor. SOLUTION: An encoder ENC compresses data and the data are stored in a memory DRAM. A decoder DEC extends data and loads them on the cache memory CACHE. Even if some overhead is generated in the access time of the memory DRAM by the processing of the decoder DEC and the encoder ENC, it hardly affects the information processing ability of the processor CPU. Thus, larger program can be dealt in the processor CPU incorporating the memory DRAM without adversely affecting information processing ability.

IPC: H04N19/176
Filed: 1993-03-25
Abstract: PURPOSE:To decrease information by selecting the significance of each partial area in a screen in a real time, and to obtain satisfactory operability. CONSTITUTION:The parallax of two video signals obtained from two cameras is detected by a parallax signal extracting means 30.
