Filed: 1988-05-26
Abstract: PURPOSE:To perform the detection of the time-out of suspended lock and the fast detection of the time-out of spin lock by setting a lock time interval value on an element taking lock, and judging it as the time-out when exceeding the time interval value. CONSTITUTION:A means 1 accessible to a timepiece mechanism reads the present TOD value, that is, the present time value represented on a common timepiece mechanism, etc., and forms new lock data in which the least significant byte is set as a CPU number, and substitutes it for lock data on a memory. Thereby, the lock is unlocked. When no success is obtained, a means 3 to judge the lock out time of the element judges comparison between the size of the TOD value and the time interval value of the lock data, and detects the lock out time when the former is larger than the latter, and repeats the above stated step when the former is smaller than the latter. In such a way, it is possible to detect the time-out of the suspended lock and that of the spin lock.

CONSTITUTION:A fluid flow rate control valve of this invention is controlled through rotation of a valve element 5 to shift its position continuously from the state that an inlet port 13 and an outlet port 14 are both communicated with one valve chamber 12a to the state that a valve chamber 12d communicated with the inlet port 13 and the valve chamber 12a communicated with the outlet port 14 are isolated from each other. In such a control valve, a first pressure-equalizing passage 13a is formed in the valve element 5 to communicate two chambers 12a, 12b located on the opposite sides of the valve element 5 with each other and to thereby making the pressures in these two chambers equal to each other. Thus, the forces acted to the valve element 5 is balanced. Similarly, a second pressure-equalizing passage 13b is formed in the valve element 5 to equalize the pressures in pressure chambers 12c and 12d and to thereby balance the forces acted to the valve element 5.

Abstract: PURPOSE:To improve the time efficiency of automatic cookig utensil equipped with a moisture and gas sensor and the like, by constituting such that a sensor element may be cleaned after a cooking start signal is inputted and the ventilation of heating compartment may be stopped until the sensor recovers its sensing capability. CONSTITUTION:An operation is started to clean a sensor simultaneously with a continuous heating of heat-cooking utensil after its cooking operation is started.

Abstract: PURPOSE:To enhance luminance of a thin film electroluminescence element by forming a light emitting layer and subjecting a base to a heat treatment in atmosphere containing water before a conductive film is formed on the base. CONSTITUTION:After a light emitting layer is formed, a base is subjected to a heat treatment at least once in atmosphere containing water before a back electrode is formed.

Abstract: PURPOSE:To make it possible to make stable rf discharge and to form a tunnel barrier layer whose permittivity is low, by performing sputtering etching of a substrate electrode in the mixed gas of two or more gases selected among He, Ne, and Ar and CF4 gas under a specified gas pressure. CONSTITUTION:The tunnel type Josephson junction element, wherein an Nb- Al superconducting thin film is used, is manufactured as the substrate.
