Title: Hydraulic controller
Inventor: MITSUI TSUTOMU
IPC: G05D16/20
Filed: 1984-08-31
Abstract: PURPOSE:To minimize hydraulic loss by disposing a supply valve upstream in relation to a drain valve. CONSTITUTION:A supply valve 20 is disposed in a control line 17 arranged upstream in relation to a drain valve 6. The supply valve 20 is perfectly identical to the drain valve 6 in its construction and a solenoid coil 21 controls the operation of a valve 22. Both valves 6, 20 are controlled in their opening/closing operation by means of an electronic circuit, when a circuit controlling the supply valve 20 receives a pressure control signal, it transmits a solenoid current increasing in proportion to the received signal to the solenoid coil 21 of the supply valve 20. Accordingly, when a signal for enlarging the opening of drain valve 6 is input therein, a solenoid signal for shrinking the opening of the valve 22 is input to the supply valve 20. Then, an amount of drain discharged from the drain valve 6 is reduced as well as the pressure in the chamber 7 of a pressure regulation valve 5 is decreased.

Filed: 1988-07-22
Abstract: PURPOSE:To automate pressure equalizing operation by stopping a signal for increasing the speed of a pump which is driven by a turbine when the pressure difference between the upstream and downstream sides of a valve installed on the downstream side of the pump becomes smaller than a set value. CONSTITUTION:An exit valve 43 is installed on the downstream side of the turbine-driven water feed pump 40 and the pressure 46 at an exist 45 and the pressure 50 of an exist header 49 are detected 44 and 48 respectively to output pressure signals 47 and 51. A computing element 52 calculates the difference between the signals 51 and 47 and outputs a deviation signal 53. A pulse generator 59 inputs the signal 53 and keeps on outputting a pulse signal 61 until the signal 53 is cased, so that a relay 62 for pump controller output setter operation turns on and off repeatedly. A comparator 54 compares the signals 47 and 51 with each other. When the signal 53 becomes smaller than the set value set by the comparator 54, a relay 55 is put in operation to break a contact 58, thereby stopping the output of the generator 59. At the same time, a contact 56 is made to turn on an exit valve opening permission lamp 57, thereby indicating that the opening conditions of the valve 43 are satisfied. Therefore, the equalizing operation is securely performed.

Title: Method and apparatus for slowly cooling heat exchanger
Inventor: YAMAMOTO SHUJI
IPC: F01K25/10
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To effectively suppress the occurrence of thermal stress in the case of slow cooling on operating a heat exchanger when started or the like by scattering a low-temperature liquid in an inlet chamber at a smaller flow rate than that when normally operated, when cooled slowly. SOLUTION: First, when started, an LNG is supplied at a smaller flow rate (smaller flow rate than that when normally operated) to an inlet chamber 22. This LNG is distributed from a master portion of an LNG supply unit for slow cooling to respective scattering portions 36, and scattered from the portions 36 toward a tube plate 25 in a wide area. Accordingly, according to this slow cooling method, local cooling due to preceding only at a lower portion of the chamber 22 like a conventional slow cooling method is not almost executed, but the chamber 22 is substantially easily uniformly cooled in an overall vertical area. Thus, a thermal stress generated at a member for forming the chamber 22 is effectively alleviated, and hence a fatigue fracture of a welded portion due to the thermal stress caused by this temperature difference can be more effectively prevented.

Title: Light emitter
Inventor: NOGUCHI YUKIO
IPC: H05B44/00
Filed: 1989-07-14
Abstract: PURPOSE:To miniaturize a transformer and prevent any generation of an audible noise by providing, in an electric power unit, a current source for operating the transformer at a frequency higher than a lighting frequency during a charg ing period to supply a charging current, and a discharge circuit for discharging a stored charge of a surface light emitting element during a discharging period. CONSTITUTION:During a period T1, a current source 1 is operative while a discharge circuit 2 is inoperative. Meanwhile, during a period T2, the current source 1 is inoperative while the discharge circuit 2 is operative. In an EL light emitter, an El lighting frequency corresponds to a basic period T; and an operative frequency of a transformer used in the current source 1, to a period (t) of a rectangular wave. Accordingly, only the operative frequency of the transformer can be sufficiently increased at the low EL lighting frequency, thereby miniaturizing the transformer. In addition, the operative frequency of the transformer can be set higher than that in an audible band, thus preventing any generation of an audible noise.

Title: Fixing device
Inventor: MIYAHARA AKIKO
IPC: H05B6/14
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent a fixing irregularity by making the temperature distribution of a thin-wall fixing roller uniform. SOLUTION: In a thin-wall fixing roller 1, reinforcement ribs 5 for preventing a strength decrease are provided in two areas, A and B, in the axial direction of it. In order to prevent a temperature decrease due to an increase in heat capacity in the ribs, the number of winds, (wind density), of a heating coil 2 is increased so as to correspond to the positions of the ribs 5. Thus, because eddy current generated in the parts increases compared to that in other parts, the heat generation increases to prevent the temperature decrease.
