IPC: F24S90/00
Filed: 1981-08-21
Abstract: PURPOSE:To increase the heat exchange ratio of the subject device by detecting whether water is within a bathtub or not, and automatically supplying hot water to the bathtub when the temperature within a hot water storage tank reaches a set value. CONSTITUTION:When the temperature of a heat collector 1 becomes higher than the temperature of water within a hot water storage tank 5, a circulation pump 4 is actuated, and the hot water is led into a heat medium heat exhanger 3 of high temperature. The heat is heat-exchanged with water within the tank 5. When the temperature within the tank 5 reaches a set value and it is confirmed by a detector 14 that no water is present within a bathtub 10, an electromagnetic valve 16 is opened, and high temperature water within the tank 5 is supplied to the bathtub 10. Although the temperature within the tank 5 is lowered by the supply water of low temperature, it is immediately heated by the heat collector 1.

Title: Resetting device
Inventor: HOSOKAWA HIRONAKA
IPC: G06F1/00
Filed: 1986-06-06
Abstract: PURPOSE:To constitute the titled device so that normal operation can be continued even if noise is applied to a trigger input, by using a clear terminal as the trigger input of a monostable multivibrator for generating a reset signal. CONSTITUTION:In case a microprocessor 1 runs away, and a trigger pulse is not outputted from an address decoder 3, an output Q of a retrigger monostable multivibrator 4 is varied from an 'L' level to an 'H' level. By such an output variation, an output Q of a monostable multivibrator 5 outputs a pulse having width of TW2, and resets the microprocessor 1. In case when noise has entered into an output signal of the retrigger monostable multivibrator 4, since a clear input terminal of the monostable multivibrator 5 is in an 'L' level, only a pulse having width of the same degree as that of the noise appears in its output Q. Therefore, a charged charge of a capacitor 14 is scarcely discharged, and the normal operation can be continued.

Title: Liquid metal ion source
Inventor: NUSHIHARA AKIRA
IPC: C23C14/32
Filed: 1986-06-06
Abstract: PURPOSE:To eliminate the contact of a filament with a sample metal, prolong the service life of the filament and enable the sample metal with high erosion property to be used by coating the filament with an insulating material having high anticorrosion and using high anticorrosion material as a reserver and needle-shaped tip. CONSTITUTION:When a heating power source 12 is operated, a current is applied through a filament 4 and lead wires 5a, 5b, to be concentrated at the filament 4 so that heat is generated and a sample metal is molten. As the temperature of the sample metal 3 becomes efficiently higher, a needle-shaped tip 6 is coated with the film of the liquid metal. Then, the high voltage power source 13 is operated, the liquid metal 3 is electrostatic-evaporated so that ion beams are generated. In this case, the filament 4 attains the high temperature such as 1500 deg.C. But the filament is prevented from the errosion because the filament is not brought in contact with the liquid metal 3. Since a reserver 1 and the needle-shaped tip 6 are brought in contact with the liquid metal, they are eroded. But, in the case that gallium is selected as the liquid metal, the rate of the erosion is slowed because the reserver 1 and needle-shaped tip 6 are kept to be relatively low temperature.

Abstract: PURPOSE:To noiselessly operate the image recorder by providing a control means which switches a cooling fan from a flow speed to high speed ventilating operation when a detected temperature of a temperature sensor comes to an alarm temperature at which the properties of a photosensitive body are damaged. CONSTITUTION:The temperature sensor 21 which detects the temperature of the photosensitive body and which is composed of thermister, etc., is arranged; temperature data detected by the temperature sensor 21 is taken in a control part 22, which is composed of a microcomputer; the data is compared with the previously set alarm temperature, and the cooling fan 12 is switched between the low speed and high speed ventilating operations. That is, when a power source is turned on, the cooling fan 12 starts ventilating at a low speed, and comes to normal idling operation; consequently, normal ventilation is carried out in an image recorder housing. Regardless of whether copying starts or not after that, the temperature Ta detected by the temperature sensor 21 is compared with the alarm temperature Tr; when the result is Ta>Tr, the cooling fan 12 is switched from the low speed to high speed ventilating operation. Thus, the photosensitive image recorder can be noiselessly operated.
