Filed: 1981-08-14
Abstract: PURPOSE:To monitor signals from a master station to subordinate stations classified into groups, by grouping those signals to transmit to the grouped subordinate stations, and arranging a monitoring signal at the head or tail of each group of signals. CONSTITUTION:Signals (b) as many as channels assigned to each subordinate station 2 are inputted to the signal allocating circuit 8 of a master station and grouped by subordinate stations. Its output signals (c) are inputted to a monitoring signal multi-channel circuit 9, which adds a monitoring signal (a) to the head of each signal group by subordinate stations to send out output signals (d). At every subordinate station 2, on the other hand, a frame synchronizing signal (monitoring signal (a) as a substitute for a synchronizing signal) is detected in the sent signals (d) by a frame synchronizing circuit 11 to obtain synchronism with the received signals (d). At this time, if a frame step-out occurs, the frame synchronizing circuit 11 generates a frame synchronism warning signal (e). The signal (d) is led to a signal monitoring circuit 12, which detects the monitoring signal (a). The monitoring circuit 12 compares its own pattern with the monitoring signal (a) to detect a code error.

Title: Skew reduction circuit and semiconductor device
Inventor: HIGUCHI TSUYOSHI
IPC: H03K5/13
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To attain the phase control in a simple circuit constitution by comparing a 1st period covering a leading edge through a trailing edge with a 2nd period covering the trailing edge through the leading edge and equally controlling both the 1st and 2nd periods. SOLUTION: A phase control circuit 11 performs control to relatively advance or delay the leading timing in different directions between leading and trailing edges. For instance, it is possible to relatively advance the trailing timing, while delaying relatively the leading timing. A period comparison circuit 12 detects the relative timing between the leading and trailing edges of a clock signal CLK1, whose phase is controlled and then controls the circuit 11 based on the detected timing. In other words, a period Thigh which covers the leading edge through the trailing edge is compared with a period Tlow covering the trailing edge through the leading edge to decide the longer of the periods. Then the circuit 11 is controlled based on the longer period decided.

Abstract: PURPOSE:To make a small-sized, light ignition device for internal combustion engines rapidly and easily, by joining a resistance element and a capacitor chip to terminals to be inserted into an outside resin case, using higher temperature than the forming temperature of the outside resin case. CONSTITUTION:An intelligent power IC 5 is constituted with a control circuit 3 and a power transistor 4. A resistor 1 and a condenser 2 are provided for surge absorption.
