IPC: F22D1/12
Filed: 1993-10-07
Abstract: PURPOSE:To enable occurrence of cavitation in a pump to be prevented by a method wherein a main bypassing pipe and an auxiliary bypassing pipe for bypassing a main circulating water pump and an auxiliary circulating water pump arranged in series are arranged and a check valve is installed in each of the bypassing pipes. CONSTITUTION:A main circulating water pump 12 and an auxiliary circulating water pump 13 are arranged in series in the midway part of a circulating water pipe 11. There are provided a man bypassing pipe 14 and an auxiliary bypassing pipe 15 bypassing each of the circulating water pumps 12, 13. Check valves 16, 17 are arranged in the midway part of each of the bypassing pipes 14, 15. Accordingly, in the case that an amount of evaporation at a discharged gas economizer 1 is more than a rated value, both check valves 16, 17 are closed and two circulating water pumps 12, 13 are operated while being connected in series, thereby even in the case that resistance in a circulating water system is increased, an amount of circulating water can be increased without reducing a discharging pressure and then a stable evaporation can be carried out within a heat transfer pipe 3. With such an arrangement as above, it is possible to prevent occurrence of cavitation at the pumps 12, 13.

Title: Enclosed type rotary compressor
Inventor: MURAI MASAYUKI
IPC: F01C21/08
Filed: 1983-12-28
Abstract: PURPOSE:To aim at reducing abrasion of a partition plate an as well at enhancing the efficiency of compression, by forming the end face of the rear part of the partition plate in such an inclined surface that it has an apex on the suction chamber side is inclined toward the compression chamber side so that the contact pressure between the end part of the partition plate and a partition plate groove formed in the cylinder is reduced. CONSTITUTION:The rear part of a partition plate 10 is formed with an inclined surface 15 having its apex on the suction chamber 11 side and inclined toward the compression chamber 12 side. With this arrangement during movement of the partition plate 10 in the direction A in which the pressure differential is large lubrication oil impinges upon the above-mentioned inclined surface 15 so that the vertical force F is effected. This force F counter-acts a force which is exerted to the compression side end part 10a of the partition plate 10 due to the pressure differential between the suction chamber 11 and the compression chamber 12 to reduce the force exerted to the end part 10a so that abrasion between the partition plate 10 and a partion plate groove 13 may be reduced to enhance the life strength of the compressor. Further, with the provision of the inclined surface 15 lubrication oil flows smoothly to decrease its fluid resistance. Accordingly, the force which is exerted to a piston 6 by the tip end 19 of the partition plate due to the fluid resistance may be reduced to reduce the abrasion, thereby it is possible to enhance the efficiency of compression.

Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To attain effective announcement for information whose priority is high by announcing announcement singing at the time of calling and reception in a tone different from that of normal calling singing at the time of detecting overlapped calling. SOLUTION: When a radio receiver 1 receives a message, a processor 105 compares and collates the received message with each information of an already received message stored in a message memory 108. When the processor 105 detects that the same message is present, announcement setting data stored in an EEPROM 104 are transmitted to a processor 105. The processor 105 urges the output of singing announcement to an announcing part 12 so that singing for indicating that the calling is present can be issued from a speaker 110, and the processor 105 outputs the received message and an icon for indicating that the overlapped calling is detected through an LCD driver 113 to a color LCD 114 so that visual announcement can be attained. After the announcement is confirmed, a key inputting part 14 is depressed for allowing the processor 105 to stop the overlapped announcement.
