Patent JP-S5871607-A (JP)
Title: Transformer
Inventor: EBISAWA YOSHITO
IPC: H01F27/28
Filed: 1981-10-26
Abstract: PURPOSE:To obtain a highly reliable transformer, by a method wherein each ultra-magnetic force generated by leads passed through an iron core window is cancelled within each iron core window, in a combination of transformers connected in parallel. CONSTITUTION:When two unit transformers A and B are connected in parallel, secondary leads 6B and 7B of the unit transformer B can be arranged near by windings 2 having the same potential when they pass through the iron core windows of the unit transformer A. Accordingly, there is not need to use long exclusive lead ducts, further high reliance is obtaned in insulation. Within the iron core window on the right side of a leg iron core 1, the apparent excitation power decreases, as the currents of the secondary leads 7B and the winding 2 flow in inverse direction to each other. The excitation power increases in the left side iron core window, as the currents of the secondary leads 6B and the winding 2 flow in the same direction. In order to cancel the effect of each excitation power generated, the winding in the iron core window through which two secondary leads 7B pass is given two more turns than the winding in the opposite iron core window.

Title: Miniature motor
Inventor: UDA SHIGENORI
IPC: H02K23/00
Filed: 1985-08-01
Abstract: PURPOSE:To prevent fratting loss from occurring due to wastage and welding of a brush commutator by impregnating the atmosphere inside a motor case with isopropylbenzyl alcohol. CONSTITUTION:A felt 16 is placed near a brush slide portion 3 on a bracket 14. This bracket is impregnated with isopropylbenzyl alcohol. Instead of the constitution as described above, a felt 16 can be fitted to the brush base 2 or provided to a motor case 20 off a brush 13. Thus the atmosphere inside the motor case becomes that of vapour of isopropylbenzyl alcohol, which is adsorbed into the surfaces of the brush and commutator segment. Consequently, the lubricating action works so well that not only the abnormal abrasion and welding of the slide contact face but the fretting damage thereby can be prevented.

Title: Safety device for car air conditioning system
Inventor: YOSHIHIRO KOUICHI
IPC: F25B1/00
Filed: 1982-09-28
Abstract: PURPOSE:To make the structure of a safety device simplifiable, by detecting a compressor discharge pressure pulsation as the number of revolutions by a pressure detecting element, in case of an air conditioning system capable of stopping a compressor driven by an engine when its revolution number reaches above the setting value. CONSTITUTION:When a positive potential feed part 18 is energized with current, the + side voltage of a comparator 50 comes high by action of a charging circuit, turning on a transistor 55 then a solenoid clutch 3a in succession, and drives a compressor. At this time, pressure at the discharge side of the compressor is detected by a pressure detecting element 13 and with the pulsation at that moment, a movable contact piece 15 interruptedly energizes terminals 16 and 17 with a continuous rating current. When the compressor is operated normally, voltage of an output part 69 at the engine side of an integration circuit is higher than that of an output part 68 at the compressor side so that the solenoid clutch 3a comes into a state of being turned on at all times. On the other hand, when interrupted continuous rating frequency between these terminals 16 and 17 per hour becomes dropped due to a drop in the number of revolutions by compressor trouble, the output part 68 at the compressor side turns high whereby the output of the comparator 50 comes to L, turning off the solenoid clutch 3a. Thus, the structure of a safety device can be well simplified.

Title: Blade for fluid transmission device and manufacture thereof
Inventor: FUKUOKA TETSUO
IPC: F16H41/28
Filed: 1992-06-04
Abstract: PURPOSE:To manufacture the blade of a fluid transmission device at a low cost without occurrence of any trouble to assembly. CONSTITUTION:The tip part of the claw part 12 of a blade 10 is processed and hardened by a press work (at a coning process). This process causes compression of the tip part of the claw part, and the thickness of the processed part is decreased to a value lower than that of a part on which coning processing is not applied. Thereafter, the end part of the processed part of the claw part is pressed and cut so as to be formed in a given shape (at a press cutting process). Since the cut part is processed and hardened, burrs are difficult to produce during a press cutting process. A process (a burr squeezing process) wherein burrs 16 produced during the press cutting process are pressed is carried out. This method corrects protrusion of burrs and facilitates a work to mount a blade on a shell 18. Since, in assembly, burrs are pressed in a shell groove in a state that the burrs are formed integrally with the blade, the burrs are prevented from being mixed in fluid in a fluid transmission device.

Filed: 1979-12-25
Abstract: PURPOSE: To improve a cutting performance by shifting a cutting tool around a workpiece so that a rake angle in a tool passage from the start of cutting to the end of it may be approximately constant, thereby facilitating the cutting treatment.  
     CONSTITUTION: When a prime mover 32 is energized, a feed screw 30 rotates and a tool table 29 is transferred. At the same time, a worm 31 rotates a worm wheel 33 and a chain wheel 36 rotates by a chain wheel 35 through a chain 37, thereby rotating a cam 34. The cam 34 advances the tool passage 13 at a given rake angle so that a cutting tool 3 may describe an equiangular spiral taking the center 2 of a work 1 as a center.
