Title: Controller for absorption type refrigerating machine
Inventor: OSAWA KAZUO
IPC: F25B15/00
Filed: 1990-06-15
Abstract: PURPOSE:To restrain the promotion of abrasion of a heat transfer tube upon low cooling water temperature operation and obtain a stabilized control by a method wherein a cooling water temperature thermostat, operated in conjunction with a vapor control valve, is provided. CONSTITUTION:When a cooling water temperature is low, a refrigerating cycle has a lower concentration than that at a specified cooling water temperature and a condensing pressure as well as the operating pressure of a high-temperature reproducer 1 are reduced whereby a solution temperature in the high-temperature reproducer 1 is reduced remarkably. As a result, a temperature difference between vapor in a heat transfer tube 12 is increased and excessive heat transfer is caused transiently, the level of drain in the heat transfer tube 12 is elevated due to excessive vapor condensation, heat transfer is balanced when a heat transfer area is reduced whereby the operation is continued. In such a condition, a thermal load per unit area of the heat transfer tube 12 is increased over a rate load and, therefore, boiling condition is violent and there can be danger that abrasion of the heat transfer tube 12 is promoted at the supporting section of a supporting plate due to the generation of vibration of the heat transfer tube 12. In order to prevent the danger, the upper limit opening degree of a vapor control valve 7 is limited by a cooling water temperature thermostat 8 when the cooling water temperature is reduced whereby the inflow of excessive vapor is prevented.

Abstract: PURPOSE: To provide a molding machine which enables tremendous increase in injection pressure in inverse proportion to the sectional area of a plasticizing chamber by forming a small plasticizing chamber at the tip of the plasticizing chamber in a pressureproof cylinder with a projection so arranged at a screw head to be inserted closely into the small plasticizing chamber.  
     CONSTITUTION: A small plasticizing chamber 9 is provided at the tip of a plasticizing chamber 4 in a pressureproof cylinder head 2 and a projection 10 is so arranged at the tip of a head 6 of a screw 5 to be inserted closely into the chamber 9. In the final stage of injection stroke, the projection 10 is inserted closely into the small plasticizing chamber 9 and the screw 5 advances to perform a rapid pressuring. As the injection pressure is inversely proportional to the sectional area of the plasticizing chamber, the sectional area of the small plasticizing chamber 9 can be reduced as compared with that of the plasticizing chamber 4. This ensures a very high injection pressure.

Filed: 1995-05-30
Abstract: PURPOSE: To make it possible to realize the measurement of an accurate distance and a broad detecting range by providing a means, which corrects the measuring distance by the width of a reflected wave. CONSTITUTION: A short-distance/long-distance switching part 10 outputs the switching command for the short-distance measurement and the long distance measurement from a port (a) of a CPU1, makes the gain of an amplifier part 8 variable, makes the detecting level of a comparing part 9 and varies the width of a transmitted wave for the short distance and the long distance in a driving circuit 2. Then, the switching of the short distance and the long distance is performed for every one cycle of the reflected wave. At the short distance, the pulse transmitting width is made wall, and the detecting sensitivity is made weak. At the long distance, the pulse transmitting width is made large, and the detecting sensitivity is made strong.  However, the error of the distance to the body to be detected may be different and larger by changing the pulse width and the detecting sensitivity at the short distance and the long distance. Therefore, the relation data table between the distance and the width of the reflected wave is formed and corrected.
