Abstract: PURPOSE: To provide a closure device which is simple in attachment/detachment, relatively inexpensive, and recyclable in a semi-permanent manner by including a pot-shaped flexible closing valve in which a side wall is partially and closely attached to the shape of a container inlet. CONSTITUTION: A lower flange 8 provided with a screw 11 is stored between a bottom part 4b of a closing valve 4 and a circular rib 7, and its diagonal edge 8a is opposite to a lower diagonal side surface. The outside diameter of the flange 8 is larger than the inside diameter, and the edge 8a of the flange 8 leans against the rib 7. This can be realized by the elasticity of a material forming the closing valve 4 having the rib 7. When the flange 8 is arranged in the closing valve 4, a head part of the screw 11 is slightly deformed by the elasticity of the bottom part 4b. Then, a flange 9 is placed on an upper diagonal side surface of the circular rib 7 by its lower diagonal edge 9a, the screw 11 is passed through its center hole, and the closing valve formed on an inlet 2 of a container 1 is inserted until hit by a support surface 6.  Two flanges 8 and 9 are tightened to each other through nuts 12, e.g. knurled buttons 13.

IPC: F25D11/00
Filed: 1989-10-20
Abstract: PURPOSE:To eliminate any damage to a relay and limit load to a compressor to the minimum by interrupting operation of a compressor and a fan motor driving relay in response to lowering of power supply voltage. CONSTITUTION:Once power supply voltage is lowered owing to abnormal AC power supply 7, DC voltage output by a diode bridge 35 is also lowered. The DC voltage output is divided by resistors 38, 39 and divided voltage and refer ence voltage of constant voltage defined by a Zener diode 41 are compared in a comparator 37. As the divider voltage is lowered by the lowering of the power supply voltage to a second predetermined value or less, a transistor 45 is turned on and a Zener diode 43 for generating the constant voltage is short-circuited. Accordingly, a power supply voltage supplying transistor 42 is turned on, and power supply voltage to a relay driving part 14 is cut. Hereby, the driving relay is prevented from being defrosted with any chattering of the driving relay.

Title: Process controller
Inventor: KOYAMA NORIAKI
IPC: G05B11/36
Filed: 1992-09-18
Abstract: PURPOSE:To provide a process controller which can suppress a reset winding up phenomenon against the alteration of a target value and which can suppress the adverse influence to a minimum even if a control loop becomes unstable. CONSTITUTION:A control arithmetic part 61 outputs a position form PID arithmetic result to an output limitter 27 from a control target value SV and a control input signal PV. The output limitter 27 outputs a control output signal MVn whose PID arithmetic result is limitted to within an upper limit value or a lower limit value. An integral arithmetic correction part 35 corrects the integral operation of the control arithmetic part 61 to the upper limit value or the lower limit value when the part 35 limits the result to the upper limit value or the lower limit value. An integral arithmetic correction judgement part 63 judges the normality/abnormality of the control input signal PV from the change direction of the control input signal PV and a direction where the PID arithmetic result exceeds the upper limit value or the lower limit value, inhibits the operation of the integral arithmetic correction part 35 at the time of judging abnormality and releases the inhibition when the PID arithmetic result returns to a value between the upper limit value and the lower limit value, for example.
