The holder 4 is formed from a magnetic material such as a plastic magnet, etc., and the bottom part 4a2 of the pocket 4a is magnetized. In rotating the bearing, the holder 4 is guided to revolve by the balls 3, and because the bottom part 4a2 of the pocket 4a is magnetized, the holder 4 is not brought to contact with the inner race 1 and the outer race 2 and adsorbed to the balls 3 composed of a magnetic material by a magnetic force.  The holder 4 is thus constrained by the balls 3 and the freedom degree in the circumferential and the axial directions is eliminated so that its whirling movement is suppressed.

Title: Intruding object detector
Inventor: TANAKA TAMOTSU
IPC: E05F15/20
Filed: 1986-04-28
Abstract: PURPOSE:To detect an intruding object irrespective of whether a reflection factor of the intrud object is good or not, and also, even if the intrud object stands still, by outputting a detecting signal in case when one of differences between mutual storage quantities of infrared-ray reflection quantities from a background, and the background and the intruding object, respectively has exceeded a threshold value. CONSTITUTION:An infrared-ray reflection quantity from a background and an intruding object, and an infrared-ray reflection quantity from the background, respectively are stored in the first integration circuit 12 whose time constant is small and the second integration circuit 13 whose time constant is large through a photodetector 3. When a reflection factor of the intruding object is large, a difference value by a differential circuit 14 of the circuit 12 and 13 exceeds a threshold value and a detecting signal of an H level is outputted from a comparator 16. At the same time, by this detecting signal, a switch of the circuit 13 is turned off through an inverter 23, the average value of an infrared-ray reflection storage value from the background is added to the differential circuit 14, and even when the intruding object stands still, the detecting signal is outputted. When an absorption factor is large and an infrared-ray reflection factor of the intruding object is small, the detecting signal is outputted in the same way, based on a difference between the storage values of the circuits 13, 12, and the intruding object is detected exactly irrespective of the reflection factor of the intruding object, and also, even when the intruding object stands still.

Title: Lever type connector
Inventor: OKUMURA HITOSHI
IPC: H01R13/639
Filed: 1993-03-30
Abstract: PURPOSE:To improve the fitting workability of a lever to a connector housing. CONSTITUTION:Shaft parts 13 are formed in a lever 10, and shaft receiver holes 6 are formed in a male connector housing 1. At the time of fitting the lever 10, when each shaft part 13 is fitted in a positioning notch part 5 and the lever 10 is pushed down, elastic deformation is generated in both or any one of an arm 11 and the outer wall part 3 by the slide-contact of the shaft parts 13 and a guide inclined surface 7, and simultaneously, the shaft part 13 is guided and inserted into the shaft receiver hole 6. Since the positioning notch part 5 and the guide inclined surface 7 have a function for guiding the lever 10 in the appropriate direction and for preventing the passing of the shaft part 13 through the shaft receiver hole 6 due to the excessive passing of the lever 10 with energizing, a make up of the work due to a failure of the insertion of the shaft part 13 into the shaft receiver hole 6 is eliminated to save the labor for the make-up work.

Filed: 1980-07-15
Abstract: PURPOSE:To reduce trouble for checking a disconnection, by transmitting a voltage signal to a receiving circuit from a transmitting circuit, in case the pulse voltage of an oscillating circuit provided on a signal transmission system is not outputted. CONSTITUTION:To an input terminal 28b of an AND gate 28 is always inputted output pulse voltage of an oscillating circuit. On the other hand, in case a signal line 9 has been disconnected, a transmitting circuit 2 is always connected to an electric power source 20, and the circuit 2 transmits at least one output voltage signal to a receiver 8, therefore, H is inputted to an input terminal 28a of the AND gate 28. In case one line 4i among input lines 41-4n has been disconnected, a corresponding light emission diode 23i is not lighted, and H is inputted to the input terminal 28a of the AND gate 28. As a result, the AND gate 28 outputs H, makes a transistor 32 conduct, and drives a disconnection display alarming circuit 11.

Abstract: PURPOSE:To perpetually make a mixed gas to produce optical fibers flow out of a saturation unit, by a method wherein raw material of liquid chlorides such as SiCl4, GeCl4, and POCl3 is continuously saturated with carrier gas such as O2 and N2. CONSTITUTION:Raw material of liquid chlorides is guided into a feed tanke 11, and guided into a feed controller 10, where the chloride gas is controlled to a specified temperature by cooling medium in a thermostat 6.
