Title: Water purifier with cooling function
Inventor: YAMANAKA KOJI
IPC: C02F1/28
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To automatically feed a somewhat cooler water when temp. of the open air is high and a somewhat warmer water when temp. of the open air is low, with a simple constitution by making a water storage tank with a synthetic resin and closely attaching a thermistor to the synthetic resin-made storage tank. SOLUTION: The water storage tank 1 for storing water is prepared from e.g. polypropylene resin and a water purifying cylinder 2 packed a filter and activated carbon, etc., and in certain cases, granite porphyry and coral stone which are a mineral production material, is housed in the water storage tank. The thermistor 7 is stuck to the water storage tank 1 and detected signal is transmitted to a control means 8 and from here a cooling instruction is transmitted to a Peltier element 5 to cool the tank. The detection temp. of the thermistor 7 adhered to the water storage tank 1 made of a less thermoconductive characteristic material causes a certain amount of error from actual temp. of the water in the water storage tank 1. Thus, when temp. of the open air is warm or low, the water is cooled much less by the value of the error.

Title: Pressure vessel
Inventor: YAMADA SEIYA
IPC: G21C13/00
Filed: 1994-05-25
Abstract: PURPOSE:To open and recover a flange in a short time by feeding a same gas as that encapsulated in a vessel, under high pressure, into a space formed on the joint face of the flange by a plurality of sealing means. CONSTITUTION:A gasket 3 fitted in a gasket groove 4 of a flange 5 isolates the inside of a pressure vessel from the outside through its sealing function, while at the same time, defines an enclosed space 16 together with the jointing faces of the flanges 1, 5. A gas identical to that encapsulated in the vessel. i.e., helium gas, is then fed under pressure higher than the inner pressure of the vessel into the space 16 to establish a pressure barrier between the inside and outside of the vessel thus isolating the inside of the vessel from the outside mechanically and physicalty. High pressure helium gas supply into a supply tank 11 is regulated 10 such that the pressure P2 in the space 16 is higher by DELTAP than the inner pressure P0 of the vessel by detecting 9 the pressure based on the signals from pressure gauges 6, 7. Consequently, gas leakage can be inhibited without welding a sealing material to the joint face and the flange can be opened and recovered in 2 short time.

Abstract: PURPOSE:To provide a refueling apparatus wherein the time elapsed from the commencement of fueling to the end of fueling termination can be reduced without causing malfunction, by starting fueling without awaiting the complete outflowing of the oil or bubbles sucked in through an opening when continuing to fuel until a tank is filled up. CONSTITUTION:As a fueling terminating means, a flow rate adjusting valve 55 employing a valve closing method is provided in a deenergizing or downstream passageway of a pump 2. When an atmospheric opening part 37 of an air supply passage 36 is plugged up with oil or bubbles, the increasing negative pressure in the air supply passageway is detected by a vacuum detection sensor 34, whereby fuel supply is suspended by the fueling terminating means for the time required for defoaming. When the fueling under suspension by the fueling terminating means is resumed, in order for the remaining oil or bubbles after intrusion into the air supply passageway to be forced out by a vacuum forming means, the time required for discharging the oil or bubbles to the vacuum forming means rather than the vacuum detection sensor 34 is set and, for this time, the fueling termination by the fueling terminating means is prevented, even if the vacuum detection sensor detects the oil or bubbles.
