Title: Frame synchronizing circuit
Inventor: ONO SHINJI
IPC: H04J3/06
Filed: 1990-01-31
Abstract: PURPOSE:To attain quick synchronization establishment and synchronization protection by adopting a variable counter for a counter counting each coincidence/dissidence pulse and applying variable control to the count number with a control circuit. CONSTITUTION:When an electric field detected by an AGC voltage inputted from an AGC terminal 3 is high and an error hardly takes place, the count of a coincidence variable counter 13 is decreased by a control circuit 24, and when the AGC voltage is low and many errors are caused, the control circuit 24 increases the count of a dissidence variable counter 14 on the other hand. Thus, no fault takes place in a peripheral equipment and the electric field is strong and almost no error is caused, the coincident count is less and synchronization is established quickly, and when the AGC voltage is low and many errors are easily caused, the dissident count is increased and the established synchronization is hardly unlocked.

Title: High withstand voltage reed switch and its sensitive value stabilizing method
Inventor: KOMURO YOSHIAKI
IPC: H01H50/54
Filed: 1991-01-21
Abstract: PURPOSE:To increase the withstand voltage and decrease its working value such that the gap between contacts does not become narrower even when high voltage is applied thereto, by arranging a non-magnetic electrode which puts the other reed piece therebetween cooperating with the reed piece to which the same polarity voltage is applied. CONSTITUTION:A non-magnetic chip 8b is used to prevent a contact part 9 and 3a from attracting each other due to the magnetization of the tip when a magnet is brought close to a reed switch 1. And, in the case where high voltage is applied between a terminal 5a and 10 of a reed piece 2a, positive charge is generated at the part 9 and at the top of the tip 8b, and negative charge at the part 3a. In this case, the part 3a receives attractive force from the part 9 as well as from the chip 8b, so that the part 3a does not move because of the equilibrium of these attractive force. On the other hand, although the part 9 and the tip 8b receive attractive force from the part 3a respectively, the part 9 and the tip 8b have respective electrical charge of the same polarity and repels each other, so that they are unlikely to be removed by the Coulomb force caused by the electric charge. Thus, its withstand voltage can be increased and width of sensitive value variation is decreased.

IPC: F16K17/36
Filed: 1980-02-23
Abstract: PURPOSE: To prevent the hunting of a valve and the leakage of fluid as well as to make a complete closing force by a method wherein a closing plate for use in blocking a valve hole in a valve body of antiearthquake operating mechanism for an opening and closing valve is made to be a large size.  
     CONSTITUTION: Under a normal operating condition, fluid flowing from a flow inlet 5 is flowed out of the outlet 6 via valve chamber 4 and valve hole 7. When a vibration caused by earthquake or something is transmitted to antiearthquake operating mechanism 1, a dilute hydrochloric acid 16 contained in a reservoir 12 is oscilated and flowed out of a small aperture 12a. When the over-flowed dilute hydrochloric acid 16 is contacted with powder of sodium carbonic chloride 17 contained in the extendable member 8, they may produce a carbon dioxide gas under a chemical reaction. The carbon dioxide gas produces a high pressure in the sealed chamber A to expand or extend the expansion member 8. With this expansion, the valve body 9 is fitted into the valve hole 7 and the angle valve 2 is closed. It is possible to increase a volume of generated carbon dioxide by adjusting a concentration of the dilute chloride acid 16.
