Title: Hot water tank
Inventor: WAKUI TOSHIFUMI
IPC: G07F13/00
Filed: 1989-06-19
Abstract: PURPOSE:To prevent boiling water from being discharged by allowing water to overflow from an auxiliary tank at the time of boiling by providing the auxiliary tank having no heat source in addition to a main hot water tank in which hot water is stored, and allowing both of them to communicate with each other. CONSTITUTION:An overflow hole 15 of an auxiliary tank 14 side is positioned in the upper part than a standard full water level of a hot water tank body 1, and a hole 10 of the hot water tank body 1 is positioned in the further upper part than the position of the hole 15. This standard full water level is set to such a level as hot water does not overflow from the overflow hole 15 of an auxiliary tank 13 side even if a water level increases due to a rise of a temperature. In this state, when stored water of the hot water tank body 1 decreases, an upper limit switch 8 outputs an alarm signal, by which a lamp is turned on or an alarm is raised, and a superintendent knows shortage of stored water. In such a way, the water level of the tank body is recovered.

IPC: C22B58/00
Filed: 1981-09-30
Abstract: PURPOSE:To economically manufacture metallic Ga by a simple process by removing impurities such as V and P from a sodium aluminate soln. separated in an Al(OH)3 depositing stage and by electrolyzing the soln. after oxidation treatment. CONSTITUTION:In the manufacture of Ga from a circulating sodium aluminate soln. prepared by the Bayer process, the sodium aluminate soln. separated in the Al(OH)3 depositing stage is cooled to cause crystallization, or a substance which acts as a seed in the crystallization by cooling is added to the soln. The seed is >=1 kind of salt selected from sodium salts of V and P and double salts each contg. sodium salt of V or P. After crystallizing and removing the impurities  such as V and P, the soln. is brought into contact with oxygen or air at high  temp. and pressure to oxidize org. matter in the soln., and caustification is optionally carried out. The soln. is then electrolyzed to manufacture metallic Ga.  The electrolyzed soln. is refluxed to the Bayer stage.

Title: Protection circuit of high voltage generator for x-ray ct
Inventor: KAWACHI HISASHI
IPC: H05G1/54
Filed: 1989-06-20
Abstract: PURPOSE:To detect a low voltage and an opening condition of circuit by outputting a signal when an output of a low-level voltage generating means is greater than an output of a voltage output, and after confirming that HV is ON, outputting an error signal when an input signal continues for a fixed time to negate the input signal. CONSTITUTION:An output voltage or a voltage in proportional to an output current is outputted from a voltage output means 1 to compare it with that of a low level voltage generating means 3 and when the voltage of the voltage output means 1 is lower, a comparison means 6 outputs a signal. After confirming by a logical operation means 8 that HV is ON, a continuation-time- confirmation means 9 outputs an error signal when the output of the voltage output means 1 is in a low level for a fixed time, and in case there is the error signal, outputs of logical operation means 10, 11 are O to make an output signal of a high voltage generator for X-ray computed tomography(CT) stop. Thereby, it is possible to cope with a trouble caused by not only overvoltage and overcurrent, but also breaking of wire, short circuit, etc.
