Title: Input/output control system
Inventor: MINEWAKI MORIYUKI
IPC: G06F13/42
Filed: 1991-02-21
Abstract: PURPOSE:To output the I/O signals under the timing conditions accordant with each peripheral device regardless of the output intervals of interruptions of a program and despite the continuous input/output instructions given from a processor. CONSTITUTION:The timer value is set to a timer register 3 from a processor 1 and the output timing interval of an I/O signal 8 is decided. Then a status signal 7 is outputted from the processor 1, and an input/output control signal production part 2 produces the signal 8 based on the instruction contents of the signal 7. The signal 8 is outputted when an output enabling signal 9 received from an access monitor timer part 4 is valid. The timer of the part 4 starts as soon as the signal 8 is changed to an invalid state from a valid state, and the output of the signal 9 becomes impossible. Then the next signal 8 is not outputted until the timer counting action is completed. A ready signal 10 which completes the processing of the processor 1 is outputted as soon as the signal 8 is changed to an invalid state from a valid state. Thus a series of input/output control operations are completed.

Abstract: PURPOSE:To easily obtain the good-quality superconducting film capable of crystallization at a low temp. by a sputtering method at a high speed by concentrically supplying gaseous O2 onto a substrate surface and concentrically supplying a sputtering gas to a target part. CONSTITUTION:The target 1 is set in a region of the high ion concn. of Ar which is the sputtering gas and a substrate 4 is placed in an atmosphere of the extremely high concn. of the O2 which is not yet ionized. The target 1 is sputtered by the Ar ions introduced 9 in this manner shown in the figure, by which the good-quality superconducting film (for example, YBa2CuX film) is formed on the substrate 4. The oxygen partial pressure is increased to the concn. necessary for forming of the thin oxide film near the substrate and the concn. of the oxygen ions or accelerated neutral particles is decreased according to the above-mentioned method. The good-quality film which has the less deviation in the compsn. distribution in the film and the compsn. with the target and is decreased in oxygen defects is, therefore, crystallized at a low temp.

Title: Absorbing type cold or hot water feeding device
Inventor: MIYAKE SATOSHI
IPC: F25B15/00
Filed: 1990-02-09
Abstract: PURPOSE:To increase a temperature of hot water while being fed by a supplying solution adjusting mechanism of a small-sized low temperature regenerator by a method wherein a temperature of hot water is detected and a supplied volume of solution for the low temperature regenerator is correspondingly controlled. CONSTITUTION:A hot water temperature is detected and an amount of liquid to be supplied to a low temperature regenerator 10 is correspondingly controlled. As an amount of supplied solution for the low temperature regenerator 10 is reduced, a heat exchanging medium in the low temperature regenerator 10 is reduced, so that a heat exchanging operation at the low temperature regenerator 10 is prohibited. With such an arrangement, a pressure saturation temperature of coolant vapor in the high temperature regenerator acting as a heat exchanging heat source for the low temperature regenerator 10 is increased. In turn, since the heating source for the supplied hot water is a coolant vapor, if the pressure saturation temperature of the high temperature regenerator 9 is increased, high hot water temperature can be attained.
