Patent JP-S63127032-A (JP)
Title: Electric stove
Inventor: ENDO SHINICHI
IPC: F24C7/04
Filed: 1986-11-18
Abstract: PURPOSE:To prevent fire hazards and burn injuries so as to improve the safety by interrupting the power supply to the heater when a sensor disposed in the upper and lower areas of a heat reflecting surface detects an object. CONSTITUTION:Sensors 13, 15 are respectively disposed in the front of the body 3 to be situated at the upper and lower areas of a heat reflecting surface 12. When either one or both of them detect an object, the resistance level of either one or both of resistors 14, 15 is caused to be changed. As the resultant resistance level R changes, a sensor circuit 23 detects the change of current in a bridge circuit 22 to activate a relay 24 by a relay operating circuit 25 so as to interrupt the power supply to heaters 1, 2. This way, a fire is prevented from occurring, and if a person contacts the guard etc., burn injuries can be prevented or lessened. The enlarged area of sensing contributes to improve the safety.

Title: Automatic system time correction device
Inventor: SEKI YUTAKA
IPC: G04C9/04
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To correct the time without affecting a normal operation by executing a time correction processing in a clock interruption processing stepwise while taking time for correction even when the event of time matching is generated in a system. SOLUTION: In the case of a processing based on a support from another computer or a standard time generator 72, the correction amount of the time is obtained as (set time) - (system present time) first and whether or not the correction value exceeds an automatic correction limit value is judged. In this case, when the correction value is larger than the automatic correction limit value, a forced time correction event processing is performed and the system present time is corrected to the set present time. On the other hand, when the correction value is smaller than the automatic correction limit value, a timing for advancing or delaying the system present time is generated by the clock interruption of one time for each clock interruption of (n) times and the system present time is corrected to the set present time.  Also, time correction for device difference correction is performed once every prescribed correction cycle.

Abstract: PROBLEM TO BE SOLVED: To obtain excellent flatness after thermal development and to prevent a print blur fault even when the material is used not only for ordinary uses, but also as a sensitive material for printing by specifying the respective curvature quantities of the end parts of four sides after thermal development. SOLUTION: One side of the outer periphery of the thermally developed photographic sensitive material after thermal development is slit to a width of about 1 cm, the side on the opposite side from the slit is placed along a straight rule, and one end of the slit is aligned with the rule, thereby forming a gap with the rule. The interval of this gap is standardized with the length of the slit side and the resulting value is called a curvature quantity. When the curvature quantity is large, the outer peripheral part of the sensitive material becomes an arc and a slack is generated since the peripheral length becomes long, so that the part causes a print blur.  The respective curvature quantities of the end parts of the four sides of the thermally developed sensitive material are preferably 0 mm/50 cm to 4 mm/50 cm, more preferably, 0 mm/50 cm to 3 mm/50 cm, and much more preferably, 0 mm/50 cm to 2 mm/50 cm.

Abstract: PURPOSE:To prevent the occurrence of a picture flowing or a shadowing phenomenon even when an image is displayed by image information for a CRT by maintaining the polarity of a pixel voltage applied when the number.of scanning lines are counted by (alpha) pieces until a next count clear time. CONSTITUTION:The counter DCNT outputs pulses PTCNT from the point of fall time of a clock signal to the point of the fall time of the next clock signal when the counter counts 239 pieces of the clock signals CL1. The output is inputted to a D terminal of a D flip-flop 1. and the clock signal CL1 is inputted to the clock terminal of the F-F 1.
