Title: Drive controlling circuit for rotary type air compressor
Inventor: NAKAMURA HIDEO
IPC: H02P1/16
Filed: 1988-01-22
Abstract: PURPOSE:To prevent an equipment loss from being generated, by a method wherein an air compressor is once stopped at the time of losing a driving power source, wherein the release of the driving power source is electrically detected, and wherein the air compressor is started a fixed time later. CONSTITUTION:From an AND circuit 4, output is generated when an air compressor breaker ON-condition 2 and the condition of an air compressor driving line voltage low-detecting-relay are materialized, and by the materialization of the condition of said voltage low-detecting-relay 1, an air compressor is stopped. By a delay relay 3, a time required for working till the AND circuit 4 and a wipe-out circuit 7 is taken into consideration. After that, when an air compressor driving power source is released, then said voltage low-detecting- relay 1 is not materialized, and output is generated from a NOT circuit 5, and output is generated from an AND circuit 8. From delay relays 10, 12 for judging the perfect stop of the air compressor, the output of air compressor start enabling signal is generated. Then, even in momentary service interruption, re-start can be performed after the perfect stop.

Title: Production of carbonic acid diester
Inventor: NISHIHIRA KEIGO
IPC: C07B61/00
Filed: 1992-01-24
Abstract: PURPOSE:To obtain a carbonic acid diester useful as a raw material for aromatic polycarbonate, etc., or as a solvent in high selectivity and yield under mild reaction condition without causing the corrosion of the reaction apparatus while keeping the catalyst in highly active state over a long period. CONSTITUTION:A carbonic acid diester is produced by the vapor-phase reaction of carbon monoxide and a nitrous acid ester. The reaction is carried out under mild condition by using a catalyst produced by exchanging the alkali metal ion, alkaline-earth metal ion, hydrogen ion or ammonium ion of a zeolite with (i) a platinum group metal ion (preferably Pd, Pt, In, Ru or Rh, especially Pd) and (ii) one or more metal ions selected from Cu, Fe, Sn, Ni, Co, Ce, Ag and Mn, preferably from Cu, Fe and Mn, especially Cu. The objective compound can be produced in high selectivity and yield by the use of the above catalyst. Since the catalyst is free from chlorine, there is no corrosion of the reaction apparatus and the catalytic life can remarkably be prolonged.

Abstract: PURPOSE: To enable a positive keeping of locked condition by a method wherein any effect may not be applied to an extension or retraction of piston rod by a spring force when locked so long as a large force as damaging the component parts such as cylinder and the like may not be applied.  
     CONSTITUTION: A valve rod 7 is depressed down from outside and valves 8 and 9 are disengaged in respect to seals 13 and 15. Thereby, each of oil chambers A, B and C is communicated to each other, and a gas pressure in the gas chamber D is acted upon the oil liquid in the oil chambers A and B through the oil liquid in the oil chamber C. As a result, the force in an elongated direction is acted upon the assembly of a piston and a piston rod due to a difference in pressure recieving areas for gas pressure corresponding to the sectional area of the piston rod 3, and then the piston rod 3 is pushed out of the cylinder 1. In turn, when the valve rod 7 is pushed up to cause the valve means 8 and 9 to be fitted in respect to the seals 13 and 15, each of the oil chambers A, B and C is made to be a closed chamber to each other, resulting in that the gas pressure in the gas chamber D may not act against the oil chambers A and B.
