Title: Tandem rolling mill
Inventor: KAWANAMI KATSUSUKE
IPC: B21B1/26
Filed: 1978-08-28
Abstract: PURPOSE: To obtain sufficient sheet gauge precision, without disposing expensive high response screw-down devices in all stands, by disposing a screw-down device of high response speed in the downstream part of stand group.  
     CONSTITUTION: In the case of automatic gauge control (AGC) by disposing high response screw-down devices in all stands, the final sheet gauge precision shows ΔH n1  as shown in curve 1. On the other hand, in the case of AGC without disposing high response screw-down devices in all stands, the final sheet gauge precision shown an inferior value ΔH n2  as compared with curve 1. However, when a high response screw-down device is disposed only in the final stand, the final sheet gauge precision is closer to the sheet gauge deviation in curve 1, indicating ΔH n3  as shown in curve 3. Further, when high response screw-down devices are disposed in the final two stands, the final sheet gauge precision is identical with that shown in curve 1. As a result, since rolling can be performed under low reduction in the downstream side stands by disposing stands for rolling high reduction in the upstream stands, the response of the screw-down device may be increased.

Title: Controlling device for dc motor
Inventor: SAITOU KUNIO
IPC: H02P23/00
Filed: 1979-08-20
Abstract: PURPOSE:To provide the inexpensive control device for the DC motor by adding analog type time constant circuits for stabilizing a control system to an armature voltage and speed detecting unit, thereby eliminating the time constant calculating function in a microcomputer unit. CONSTITUTION:When detecting the armature current and voltage and the field current of a DC motor and applying armature and field current instruction values by a program control type processor to thereby control the speed of the motor to the field-weakening range, the time constant circuit G1 is added to the speed detecting unit TG and the time constant circuit G2 is added to the armature voltage detecting unit. The outputs from the circuits G1 and G2 are applied to the speed deviation unit in the armature and field current control systems and to an armature voltage vs. control voltage generating unit EF for control. Accordingly, complicated time constant calculation cannot be necessarily executed in the microcomputer unit, and the configuration can be consequently simplified as an inexpensive control device.

Title: Space cooling hot water supply device, space heating hot water supply device and cooling/heating hot water supply device
Inventor: TAKAHASHI SHOJI
IPC: F25B29/00
Filed: 1988-04-28
Abstract: PURPOSE:To prevent the generation of flushing gas in refrigerant, by installing a bypass pipe which bypasses a hot water supply heat exchanger and a change over mechanism which changes over the flow of refrigerant to the piping which forms a refrigerant circuit. CONSTITUTION:A refrigerant pipeline 5 which forms a refrigerant circuit is provided with a bypass pipe 8 which bypasses a hot water supply heat exchanger 7 and a change over mechanism 9 which changes over the flow of refrigerant where a change over valve is used as the change over mechanism 9. When the change over mechanism 9 is manipulated, the refrigerant which flows from a condenser 2 is changed over into a refrigerant flowing through a hot water supply heat exchanger 7 and a refrigerant flowing out through the heat exchanger. Therefore, during cooling operation and heating operation, when the refrigerant is heat- exchanged and condensed with a heat exchanger which serves as a condenser, the refrigerant is reduced to a low temperature. When the temperature of this refrigerant drops below the temperature of make-up water which is to be heat-exchanged with the hot water supply heat exchanger, the refrigerant is fed to a throttle device, bypassing the hot water supply heat exchanger, thereby preventing the heat exchange between the refrigerant and the make-up water, which makes it possible to prevent the generation of flushing gas in the refrigerant.
