Patent JP-H02275267-A (JP)
Title: Accumulator and setting method thereof
Inventor: TAKAO HIROMI
IPC: F25B43/00
Filed: 1989-04-17
Abstract: PURPOSE:To prevent a compressor from sucking a liquid refrigerant at the time of operation by a method wherein a liquid tank is wrapped by a double structure and the tank is arranged at a location lower than the compressor in a gravitational direction and at the suction side of the compressor a pressure switch and a relay operated at a set suction pressure are installed. CONSTITUTION:The outer circumference of a liquid tank 1 is wrapped by a cylindrical tank 2 and a cover 3 and another room which has a double tank structure and keeps a perfect air tightness from the tank 1 is installed. The low pressure refrigerant from a vaporizer is caused to flow through a large space in the tank 2 and gasified by using the heat of the high pressure refrigerant in the tank 1 and then is sent to a compressor through a discharge hole 5 installed at the bottom of the tank 2. Next, by the reason that the location of the tank is lower than the compressor in a gravitational direction, the residual refrigerant liquid in the vaporizer and piping is able to be accommodated in the tank inside. Further, a pressure switch 6 and a relay 7 operating after detecting the pressure in the tank 2 are arranged between the coils of a voltage relay 9 controlling an electromagnetic clutch 8.

Title: Cylindrical alkaline primary battery
Inventor: KOGURE HARUO
IPC: H01M6/08
Filed: 1982-06-03
Abstract: PURPOSE:To prevent any disruption of a cylindrical alkaline primary battery by suppressing the increase in its internal pressure by installing a spongy cadmium metal on the negative mixture. CONSTITUTION:After a cylindrically formed positive mixture 5 consisting of mercury oxide, manganese dioxide and graphite is inserted into a metallic case 4, the case 4 is provided with an annular groove. Next, after a separator 6 is placed inside the cylindrical positive mixture 5, electrolyte is poured, then a negative mixture 7 made of a kneaded mixture consisting of zinc, the electrolyte and a thickener is packed. Next, a separating sheet 10 having a center hole through which a current-collecting member 2 penetrates is positioned inside the separator 6, then a spongy cadmium metal 9 is placed on the separating sheet 10. After that, a sealing plate which has a current collector and is combined with a sealing ring 3, is placed on the annular groove of the metallic case 4 so as to seal the battery. Here, in order to increase the reactivity of the spongy cadmium metal 9 with oxygen, the metal 9 is moistened by the electrolyte beforehand. As a result, since the spongy cadmium metal 9 changes into cadmium hydroxide by reacting with oxygen which diffuses into the negative mixture 7 after being generated in the positive electrode when the battery is charged due to connection error or the like, any increase in the internal pressure of the battery is prevented temporarily.

Abstract: PURPOSE:To improve the compression ratio against facsimile signal having multilevel gradations as dither pictures have, by encoding an altered block of the address of the starting block with a code indicating the block value and the value of run length. CONSTITUTION:A comparator 32 judges whether the absolute value of the content of a counter 22 is within , for example, ''3'' or not, and outputs ''1'' when the absolute value is within ''3'' or ''0'' when the value is outside the range. When the signal from P3 is ''1'' and that from the comparator 32 is ''1'', the gate 62 is opened and the content of the counter 22 is encoded by a vertical mode encoding circuit 42. On the other hand, a counter 21 is increased one by one from the time when an address controlling circuit 6 sets a0 and stops the countine when it receives an ''1'' signal from P11. A gate 61 is the one which is opened when the output of the comparator 32 is ''0'' or the signal of P5 from a coincidence circuit 8 is ''0''. Block values passed through the gate 61 are inputted into a horizontal mode encoding circuit 41 and encoded.

Title: Signal synchronizing system
Inventor: YOSHIDA KAZUYOSHI
Filed: 1987-04-22
Abstract: PURPOSE:To avoid the synchronizing error of a slave station from getting larger by setting a flag representing defect of synchronization in a synchronizing data frame when a master station cannot send a synchronizing data frame. CONSTITUTION:A master station 11 for synchronization sends idle data frames DSA and DSB prior to the transmission of a synchronizing data frame D1. The length of the idle data frame DSB is varied in response to the time when the master station 11 receives tokens T1-Tn. Moreover, when the master station 11 cannot send the synchronizing data frame D1 due to delay of token arrival or the like, a flag representing defect of synchronization is set to the data field of the synchronizing data frame D1. Slave stations 12-1n, in detecting the said flag, disregard the synchronizing data frame D1 as the synchronizing signal. Since the signal synchronization of the slave stations is maintained with high accuracy, the stable signal synchronization is attained by using a token passing bus.
