Abstract: PURPOSE:To obtain compact and light hot-water supplier having high fast- heating by a method wherein a heat exchanger provided on the high temperature side of a heater body water chamber is consisted of pipes body flatted for the longitudinal direction of the water chamber. CONSTITUTION:The predetermined amount of the water is supplied to a bath 38, further, is supplied to a filter case while a circulating pump 27 and the heater body 3 are filled with water. When the circulating pump 27 is operated, the water in the bath 38 is circulated like an arrow due to suction force. Then, the water in the water chamber becomes high hot-water by heating, therefore, the water circulating the bath 38 is heated by the pipes body 3. The pipes body 3 are consisted of the pipe body flatted for the longitudinal direction of the water chamber, therefore, the dimension of intervals between the outside body, the inside body and the pipes body becomes large while the natural convection of the hot-water in the water chamber becomes easy. As a result, the characteristic of the heat exchange for the circulating water is improved. In other wards, the bath having high fast-heating may be obtained upon additoinal heating.

Title: Operation control device for torque converter clutch in speed change gear for car
Inventor: NISHIMURA SADANORI
IPC: F16H61/14
Filed: 1982-02-04
Abstract: PURPOSE:To prevent transmission of reverse driving force at the time of deceleration by cutting off the action of a car velocity signal upon a direct-coupled clutch control valve when a throttle opening is less than a predetermined opening, so that a clutch is forcedly restored to a disconnection state. CONSTITUTION:When an acceleration pedal is restored to reduce the speed, a throttle opening is reduced to less than a predetermined opening to operate a car velocity signal cut-off device 27. As a result, governor pressure is stopped feeding to a control valve 21 controlled by governor pressure for interrupting a direct-coupled clutch 19, and the control valve 21 is returned to a clutch disconnection position so as to disconnect the clutch 19. When the clutch 19 is disconnected, the reversion driving force from driving wheels is absorbed in slip in a torque converter 4, to be kept from transmitting to an engine.

Title: Thin film forming device
Inventor: MORINO YASUNORI
IPC: C23C16/44
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To remove the adherent matter of any adherent film and reaction product in a thin film forming device thereby suppressing the adherence to the reaction chamber innerwall by providing the reaction chamber for formation- processing a substrate with a gas feed port feeding the gas for exciting swivel flow in the reaction chamber as well as an exhaust port exhausting this gas. SOLUTION: A dilute gas is led in from a dilute gas feed port 20 to be exhausted from an exhaust port 6 for exciting the swivel flow 40 in the reaction chamber 1. For example, in case of the thin film forming device, before carrying a wafer the reaction chamber 1, H2 gas in large flow rate is fed from the dilute gas feed port 20 simultaneously exhausting the gas contained in the reaction chamber 1 from the vacuum exhaust port 6 so as to excite a swivel flow 40 in large flow velosity along the innerwall of the reaction chamber 1. Through these procedures, the adherent film and adherent matter can be brown up to be removed. Furthermore, during the formation processing step on a wafer 9, the formation of the adherent film on the innerwall of the reaction chamber 1 due to the swivel flow excited by the dilute gas along the innerwall of the reaction chamber 1 can be suppressed.

Title: Method for maintenance of electron beam exposure device
Inventor: OSADA TOSHIHIKO
IPC: H01J37/20
Filed: 1979-02-13
Abstract: PURPOSE:To eliminate charge up to be caused by lubricant oil by coating synthetic fluorine lubricant on mechanically sliding parts in a vacuum tank of an electron beam exposure device. CONSTITUTION:Synthetic fluorine lubricant is a lubricant oil devloped from the consideration of the fact that fluorine resin has a low friction coefficient and that it has no tackiness. It has relatively low cohesive energy, smaller than 1800(calmol<-1>) as expressed by Equation I. For maintenance, the sliding parts in the movable structures of the device are throughly cleaned and then they are coated with thin synthetic fluorine lubricant oil. As a result, even if a minute quantity of lubricant is evaporated, when it is exposed to an electron beam, it is decomposed into CF2 gas, CF3 gas, and O2 gas, and these gases are sucked into a exhaust device connected to vacuum tank 1 and are removed.

Abstract: PURPOSE:To manage accurately an internal time and display the internal time with a high precision even if clocks whose period is shorter than the execution time of an instruction are adopted, by providing a counter in an information processing system. CONSTITUTION:An elapsed time value storage address on a main storage 2 is set preliminarily to a main storage address register ADR100. A control storage 110 performs the control so that a selector 106 selects the output of a counter 3, and instructs to an arithmetic circut ALU104 to substract the output of the selector 106 from contents in a selector 105 and sets the result to a register 103. If this result is positive, contents of the register 103 are written as a new elapsed time value on the main storage 2. If the result is zero or negative, a preliminarily prepared initial value is added. The counter is provided in the information processing system in this manner, thereby managing the time accurately and displaying the internal time with a high precision.
