Title: Pointer signal generating circuit
Inventor: MATSUSHIGE HIROMI
IPC: G11B20/18
Filed: 1990-09-14
Abstract: PURPOSE:To increase the correcting capability of an error correcting algorithm by generating a pointer, which indicates continuity of the number of '0's larger than the number of '0's restricted by a (dk) run length code, in the case of a signal where discrimination error occurs by severe drop-out. CONSTITUTION:If data error occurs in a reproduced analog signal because the signal which should exceed a prescribed level does not exceed it by noise or drop-out, the period of continuity of '0's is monitored by a reference clock to generate the pointer. When the amplitude of data is reduced to cause errone ous discrimination of data in this manner, an error pointer signal is generated by output mutual monitor of a signal detecting circuit and a pointer detecting circuit. Thus, even the signal which does not exceed the signal detection level and the signal which exceeds the detection level but has a very high probability of error can be accurately instructed, and the capability of the error correcting algorithm is increased.

Title: Multi-address link control system
Inventor: OSAWA TOMOYOSHI
IPC: H04L12/18
Filed: 1992-09-11
Abstract: PURPOSE:To attain a multi-address communication when a sufficient worth is recognized even when reception is not executed by entire stations by transmitting a multi- address transmission request at the time of opening a link, counting the number of reception stations which responds to the request, and controlling the multi-address transmission. CONSTITUTION:A transmission station 1 is started by the trigger of the multi-address transmission start. At first, the transmission station 1 transmits the transmission requests to reception stations 2 and 3, and starts a timer for setting a waiting time until the reception stations 2 and 3 transmit the response. Then, the transmission station 1 searches the response from the reception stations 2 and 3 until the timer is time-out, increases a coefficient unit by '1' each time the response is transmitted, discriminates whether or not the value of the coefficient unit is beyond a threshold value after the time-out, and starts the multi-address communication when it is beyond the threshold value. Moreover, this system is equipped with a means which adds a value indicating the number of times of request to the multi-address transmission request, and it is preferable that the value indicating the number of times of request is increased, and the request is issued again when the value of the coefficient unit after the time-out is less than the threshold value.

Filed: 1992-09-11
Abstract: PURPOSE:To reduce the current density of a transmission line in order to suppress the transmission loss and to attain a compact structure by providing a wide separate conductor to be a pair with a ground conductor and above a dielectric substrate at the prescribed height and forming an air layer between the separate conductor and the dielectric substrate. CONSTITUTION:A separate conductor 1 having the larger width than a strip conductor 4 is provided above a dielectric substrate 2 by a supporter 6 so that an air layer is formed between the substrate 2 and the conductor 1. Thus, the line capacitance is extremely reduced by the air layer per unit length of the line. Therefore a prescribed level of impedance is secured with reduction of the capacitance per line unit length even through the width of the conductor 1 is increased for reduction of the current density and also the thickness of the substrate is reduced for a compact structure. In such a constitution, the increase of the current density can be reduced for a transmission line so that the transmission loss is suppressed and a compact structure is attained.
