Patent JP-S6486619-A (JP)
Title: Digital signal processing circuit
Inventor: TAKEUCHI SADAJI
IPC: H03M1/70
Filed: 1987-09-28
Abstract: PURPOSE:To improve the processing speed by providing a circuit applying the correcting processing to the result of final arithmetic result within a word length able to be handled by a circuit of the next stage to the pre-stage where the result of final arithmetic operation is outputted to an external circuit (circuit at next stage such as D/A converter) so as to process the data independently of the arithmetic circuit. CONSTITUTION:The content of an exponential part buffer 21 and an output of a constant generating circuit 30 are compared by a comparator circuit 40. When the output of the constant generating circuit 30 is larger than the content of the exponent part buffer 21 as the result of comparison, a selection circuit 60 outputs a minimum value outputted from a minimum value generating circuit 51 externally through a fixed decimal point data output terminal. When the output is smaller than the content of the buffer 21, the selection circuit 60 outputs a maximum value outputted from a maximum value generating circuit 50 externally through the fixed decimal point data output terminal. A D/A converter 5 converts the digital signal in m-bit width outputted into an analog signal. Thus, the arithmetic circuit can start the processing to the succeeding digital signal inputted in time series without awaiting the completion of the processing required for the output.

Abstract: PURPOSE:To provide insulative resin paste excellent in workability at the time of dispensing by including essentially a specific phenol novolak type epoxy resin, a specific phenol resin hardener, and silica powder having a specific particle diameter. CONSTITUTION:Insulative resin paste including essentially a phenol novolak type epoxy resin expressed by Formula I (A/B is 2 or more wherein A represents a quantity in the case of n=0, and B represents a quantity in the case of n=1), a phenol resin hardener expressed by Formula II (C/D is 2 or more wherein C represents a quantity in the case of n=0, and D represents a quantity in the case of n=1), and silica powder having an average particle diameter of 1-20mum and a maximum particle diameter of 50mum or less is used for bonding a semiconductive element of an IC, an LSI or the like to a metal frame or the like. An equivalent ratio of an epoxy group contained in the epoxy resin to a hydroxyl group contained in the phenol resin hardener approximately ranges from 0.5 to 1.5, preferably, from 0.8 to 1.2. The insulative resin paste is low in elasticity so that generation of a crack, curvature, and void and deterioration of mechanical strength can be prevented.

Abstract: PURPOSE:To eliminate the superposed part of a wiring metal film of single layer thereby to stabilize the output temperature characteristic of a pressure detector and to improve the reliability of a signal processor by forming the thickness of a wiring metal film thickly at the processor and thinly at the detector. CONSTITUTION:A pressure detector 101 formed on a substrate 11, and a first wiring metal film 41 formed on a signal processor 102 are wired only at the detector 101, a second wiring metal film 42 is then formed on the whole surface, and a photoresist 43 is formed so that a wiring pattern remains only on the processor 102.

Abstract: PURPOSE:To continue communication in other control station even any one of plural control stations is made into a stopped state by temporarily storing messages collected by the polling selecting of one control station in each memory provided for each of other control stations. CONSTITUTION:A communication control equipment 1 selects a polling signal at the side of a control station 2a and causes to flow the polling signal to a low-order port 5, and return messages from a group 3 of stations to be controlled are not directly transmitted to control stations 2b-2n in high-order ports 4b-4n except a high-order port 4a but once stored in transmission buffer memories 12b-12n. When the polling signal from the high-order port 4a is discontinued for a fixed period, the discontinuity is detected by a polling supervising timer 11a, and the polling signal of the high-order port 4b is caused to flow to the low-order port 5 by driving a switching means 13. Thus, even when the polling of the first high-order port is stopped, the return messages can be obtained by causing to flow the polling signal of other high-order port to the low-order port.
