Title: Method for refining heat resisting alloy excellent in room temperature elongation characteristics
Inventor: KAMOTO TERUO
IPC: C22C30/00
Filed: 1989-10-03
Abstract: PURPOSE:To improve the yield of Ti addition, to reduce the contamination of molten metal with TiO2, and to produce a heat resisting alloy excellent in room temp. elongation characteristics by carrying out refining in a vacuum atmosphere at the time of refining an Ni-Cr-Co heat resisting alloy. CONSTITUTION:At the time of refining a heat resisting alloy having a composition consisting of, by weight, 0.3-0.6% C, <2.0% Si, <2.0% Mn, 22-32% Cr, 26-42% Ni, 9-26% Co, 3-16% W, 0.05-2.0% Ti, and the balance Fe, the atmosphere in the refining is controlled so that it is a vacuum atmosphere of <=5.0mmHg during the period between the initiation of refining and 30min at the longest after the initiation of refining, and further, the additive quantity of Ti is regulated to <=2.5%. Since the oxidation of Ti does not occur and deterioration in the cleanliness of the molten steel due to TiO2 is prevented because the refining is performed in vacuum, the heat resisting alloy excellent in room temp. elongation characteristics can be stably produced.

Title: Electronic device of back board structure
Inventor: YAMADA HIROSHI
IPC: H04L25/02
Filed: 1990-09-28
Abstract: PURPOSE:To realize isolation among slots at a low cost by arranging a diode whose forward voltage drop is larger than that of a photocoupler of a slave circuit in parallel with a light emitting element of the photocoupler at a slot of a master circuit. CONSTITUTION:When a slave circuit 14 is connected to a slot 13, a current flows to a photocoupler 15 automatically. In this case, diodes 11, 12 are interrupted. Moreover, when a slave circuit 14 is disconnected, the current flows automatically to the diodes 11, 12 and gives not effect on a current loop. On the other hand, since a slave circuit is not mounted to a slot 33, the current flows to diodes 31, 32. When a slave circuit is mounted to the slot 33, the current flows to a photocoupler in the slave circuit automatically. Thus, even when a circuit is inserted/withdrawn to/from the slot of the back board, the current from a master circuit M is switched automatically without giving any effect on other circuit portions.

IPC: F15B11/028
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To accurately correspond to a recovery of a single acting hydraulic actuator to switch a selector valve into a neutral position. SOLUTION: A hydraulic booster device is constituted with a hydraulic booster 30, a single acting clamp device 80 which is actuated by being supplied with a high hydraulic pressure from the hydraulic booster 30, a selector valve 40, a drain valve 50 which is capable of draining hydraulic oil in a secondary side supply passage, and a pressure sensor 57 and an oil temperature sensor 72 which detects an oil pressure and an oil temperature of the secondary side supply passage.  In such a case, after the clamp device 80 is actuated by switching the selector valve 40 to an actuating position and supplying the clamp device 80 with a high hydraulic pressure from the hydraulic booster 30, the selector valve 40 is switched to a recovery position when an oil pressure detected by the pressure sensor 57 reaches a specific pressure, and then the selector valve 40 is switched to a neutral position after a drain time passes which is set so as to correspond to a hydraulic oil temperature detected by the oil temperature sensor 72.

Title: Magnetic recording and reproducing device
Inventor: KOTODA YOSHIHIRO
IPC: G11B15/44
Filed: 1985-11-21
Abstract: PURPOSE:To reduce the size and weight of a capstan motor by utilizing the driving force of a rotary cylinder to drive a reel board at the time of quick feeding and rewinding modes. CONSTITUTION:When a mode slider 21 is moved to a position shown in a figure to operate each of the quick feeding and rewinding modes, both control levers 11, 12 are turned in the counterclockwise direction, gears 14, 18 are separated and gears 13, 17 are engaged from/with the control levers 11, 12. Thereby, driving force generated by the rotation of a cylinder motor is directly transmitted to a reel gear 22 through a belt 26 without being passed through a cltach felt 24 to drive the reel board. Since the rotational direction of the rotary cylinder 1 coincides with the traveling direction of a magnetic tape 6, the traveling load of the magnetic tape 6 is reduced and a margine can be generated in the driving force of the rewinding operation. The tensile force of the belts 26, 27 is increased only when the rotational force is transmitted and the tensile force is weakened in other cases, so that useless torque loss is not generated.

Title: Heat pump type air conditioner
Inventor: MACHIDA KAZUHIKO
IPC: F25B13/00
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To draw out performance of an indoor heat exchanger at the time of a cooling operation at a maximum limit. SOLUTION: A pulse type motor driven expansion valve EV is fully opened, and a compressor 1 is started to be driven. A temperature difference Δt between an inlet and an outlet from an indoor outlet piping temperature t2 and an indoor inlet piping temperature t1 at the time of elapsing a predetermined time Δτis set to a first reference temperature difference Δto1, and a result obtained by subtracting the difference Δto1 from the difference Δt during continuously operating of the compressor 1 thereafter is set as a sensed supercooling degree SH.  Then, an opening of the valve EV is decreased so that the sensed degree SH becomes a first predetermined sensed supercooling degree SH1 or more, and when the degree SC becomes the first degree SC1 or more, the opening p1s1 of the valve EV is contrarily set to a large value by a first predetermined opening Δp1s1. Accordingly, a refrigerant supercooling degree of an outlet of an indoor heat exchanger 1 is not largely assured, but substantially supercooling degree SH=0 is approached, and hence the performance of the exchanger can be achieved to a maximum limit.

Title: Solar light generation system
Inventor: OKUZAWA KATSUHIRO
IPC: H02J3/38
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent an inverse power flow in a solar system generation system by a method wherein a cycle at a zero-cross point of a commercial power supply is monitored at all times and a change in the cycle at the stoppage of power of a distributing system is detected with high accuracy without being influenced by a noise and then the solar light generation system is paralleled off from the distributing system. SOLUTION: A zero point detection signal generating circuit 20 generates a pulse-like zero point detection signal at a zero-cross point and a chattering preventive circuit 29 removes chattering of the zero point detection signal. When a set value is input, a frequency divider 22 divides a clock 21 to any detection accuracy. A counter 23 measures a cycle at the zero-cross point and then comparators 24, 25 determine whether the measured value is within an allowable range or not. When the measured value is abnormal, a signal is output from an OR circuit. A counter 27 and a comparator 28 determine whether the signal output from the OR circuit is due to a noise by the instantaneous power stoppage or not. When the signal is found abnormal, an error signal is output to notify that there is a trouble.
