Title: Automatic equalizer
Inventor: TAWARA MASATO
IPC: H03H21/00
Filed: 1986-12-25
Abstract: PURPOSE:To improve the pull-in characteristic by making the timing of the start and stop of a reset operation nearly equal to the timing of start and stop of the oscillation of a timing oscillator, thereby evading the reset operation from being a hindrance to the pull-in operation. CONSTITUTION:When distortion of a transmission line is increased and exceeds an equalization limit, the carrier synchronization of a demodulator 2 goes to out of synchronization and the automatic equalizing circuit 1 is brought into the asynchronizing state, an oscillator 4 is started, a reset signal generator 5 directly responds to an output 11' of the oscillator 4 to apply the initial value supply to the automatic equalizing circuit 1. When the transmission line distortion is decreased and the carrier synchronization is established while within the equalization limit range, the oscillator 4 stops oscillation and a reset signal generator 5 has no time delay to stop the set operation. Thus, the adverse effect that the reset operation gives hindrance to the pull-in of the automatic equalizing circuit is eliminated.

Title: Manufacture of coil spring
Inventor: MURAI TERUYUKI
IPC: C23C8/26
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To omit an oxide film removing process and to reduce hours required for nitriding by applying low temp. annealing and nitriding after spring forming using an oil tempered wire specified the thickness of surface oxide films in the case of manufacturing coil springs. SOLUTION: Spring forming, low temp. annealing and nitriding are successively applied to manufacture coil springs based on the oil tempered wire wherein the thickness of surface oxide films is <1.5-3.0μm. Further, if necessary, shot peening is applied. The upper limit of the thickness of oxide films is preferably specified to be <=2.0μm. The control of the thickness of oxide films is performed by heating and quenching wire stocks under an inert gas atmosphere such as gaseous nitrogen, etc., or under a low oxygen partial pressure atmosphere, and by further tempering them under an inert gas atmosphere. By this way, coil springs are manufactured without applying the oxide film removing process before nitriding.

CONSTITUTION:Hot water in a hot water storing tank 15 heated by a heater 16 is partially flowed to a main circulation circuit 17 and partially flowed to a sub- circulation circuit 20. The hot water flowed to the sub-circulation circuit 20 is passed through a feeding pipe 23 and injected by an injection nozzle 24 arranged within the open type deaeration box 21 and then corrosive gas such as oxygen or chlorine melted in the hot water is completely removed. The hot water after deaeration is stored once in the open type deaeration box 21, then fed out through a feeding-out pipe 26 under operation of a forced pump 22 and then returned back into the hot water storing tank 15. A repetition of this action causes the hot water stored in the hot water storing tank 15 to be completely removed and at the same time the hot water circulating in the main circulation circuit 17 is also completely removed and the corrosion of pipings and equipment is prevented.

Abstract: PURPOSE:To preclude the dew condensation and freezing of a humidity sensing element and to improve the reliability of a humidity sensing function through a former half period by warming up the humidity sending element by a heat generating body through a temperature sensing circuit when temperature drops. CONSTITUTION:If the temperature drops during the use of a circuit until the humidity sensing element which constitutes a humidity sensing circuit 1 enters a dew condensation state, a temperature deciding circuit 6 decides the temperature sensed by the temperature sensing circuit 5 and a heat-generating body driving circuit 4 operates to supply a current to the heat generating body 3 and warm up the humidity sensing element, thereby preventing its dew condensation and freezing. When the temperature rises until the temperature sensed by the circuit 5 rises above the discrimination temperature of the circuit 6, on the other hand, a delay timer circuit 7 connected to a discrimination output higher than the discrimination temperature of the circuit 6 operates a certain time later to reset an inhibiting circuit 2 connected to the output of the delay timer circuit 7, and consequently humidity detection and measurement which are stopped temporarily becomes possible to preclude the dew condensation and freezing of the humidity sensing element completely.

Filed: 1992-10-26
Abstract: PURPOSE:To secure safety and reliability at low cost by rotating an auxiliary floor plate always placed in an erected condition by being energized by a spring cylinder to a horizontal position by operation of a cam when an elevator arrives. CONSTITUTION:An auxiliary floor plate 30 is put always in an erected condition by being energized by a spring cylinder 35. At this time, when an elevator 10 is raised from the lower part of a pit 20, the auxiliary floor plate 30 is pushed upward by a roller 16 through a cam arm 33, and escapes elastically outward slightly temporarily, and allows ascension of the elevator 10.

In this way, only when the elevator 10 arrives at respective entrance and exit floors, the auxiliary floor plate 30 is rotated automatically to the horizontal position, and blocks up clearance between it and the elevator 10, and except that, it is rotated to a vertical position, and acts as an invasion preventive fence.

Title: Optical fiber and optical cupler protected at non-reflection terminal
Inventor: SUZUKI FUMIO
IPC: G02B6/28
Filed: 1994-12-14
Abstract: PURPOSE: To lessen the inversion reflection at an end face and to prevent the occurrence of breakage of optical fibers by bending, etc., and the consequent reflection from the broken surface by coating the terminal part subjected to a non-reflection treatment with a synthetic resin. CONSTITUTION: This optical fiber coupler 20 is an optical fiber coupler of 1×2 type formed by subjecting the end face 24 of the terminal part 21 of an unnecessary port to the non-reflection treatment. The terminal part 21 is paralleled with the base part of a port 9a led out of the same side of a protective case 8 and the part where both optical fibers are paralleled is coated integrally by an elastic resin 25 of a silicone resin system. Then, the outer periphery and the end face 24 of the terminal part 21 are both protected against impact and even if external force acts thereon, the independent bending of the terminal part 21 does not arise and, therefore, the resistance against thee bending is improved.  As a result, a crack and breakage are hardly induced and the failure of the port 9a in the assembling operation of the optical fiber coupler 20 is prevented and the reflection noises are hardly produced.
