Title: Rotary compressor
Inventor: SHIBUYA TSUNENORI
IPC: F04C29/02
Filed: 1983-10-06
Abstract: PURPOSE:To prevent the leak of oil and gas from a sealing part by installing a check valve into an air hole which communicates to a sealing chamber and a chamber and opening said check valve by the pressure in the sealing chamber when a compressor stops. CONSTITUTION:A check valve 40 installed onto a front head is opened on a suction-chamber 15 side and is constituted of a hole 42 equipped with a covering body 41, small hole 43 extending in the direction of a shaft 1 from the bottom part of the hole 42, and a port 44 which communicates between the small hole 43 and a sealing chamber, and a ball 45 is used as valve piece. When a compressor stops, the pressure Pd in a discharge chamber 18 is temporarily increased higher than the pressure Pm in the sealing chamber, and then immediately the following state is formed; Pd<Pm. Therefore, the pressure in the sealing chamber can be released into the discharge chamber 18.

Filed: 1983-10-06
Abstract: PURPOSE:To eliminate measurement errors without dividing the process into finely divided steps, by correcting the reference point by means of changing it automatically following the temperature changes and measuring frequency. CONSTITUTION:When temperature is A1 deg.C with the zero-point Z1 of a measuring instrument 12, the zero-point Z1 held in a zero-point holding circuit 13 is stored and at the same time, the temperature value A1 deg.C from a temperature sensor 11 held in a zero-point holding circuit 18 is stored in the old temperature memory circuit 19. Next, after the lapse of the specified length of time, when temperature is A2 deg.C at the output value Z2 of the instrument 12, a difference Z2-Z1 is outputted from computer circuits 16, 21 and a dividing circuit 22 delivers (Z2- Z1)/(A2-A1) to be stored in a zero-point changeability memory circuit 23 and the result is applied into a multiplication circuit 25. By the two zero-point measurements, an inclination of changes of the zero-points is set and a zero-point including few error following the changes of temperatures is outputted from an adding circuit 26 as an output.

Title: Heat treatment of coal
Inventor: SATO FUMIAKI
IPC: C10L9/08
Filed: 1985-08-28
Abstract: PURPOSE:To obtain a highly valuable coal, economically by thermally modifying a low-quality coal with a hot gas, wherein the surface moisture is removed in the first step, a rapid heating to a specific temp. is effected using a hot gas in the second step, and the exhaust gas from the second step is used as a heating gas in the first step. CONSTITUTION:A coal having a low carbon content and a high equilibrium moisture is modified by heating with a hot gas. In this heat treatment the final heating temp. is defined as 180-300 deg.C exclusive, the heating step is divided into two steps, and the exhaust gas from the second step is used as a heating gas in the first step. As said hot gas is used an inert gas having an oxygen content of at least 10vol%, a hot gas contg. at least 10vol% steam, or a 100% steam for preventing the burning of coal or explosion. By heating the coal above 180 deg.C, the internal moisture of the coal is decreased and the oxygen-contg. hydrophilic groups, such as a phenol group and a carboxylic group, are thermally decomposed to be eliminated so that the coal becomes hydrophobic, and the hygroscopicity is decreased. Also, an oxygen content of the coal is decreased, thus preventing autogeneous ignition.
