Abstract: PURPOSE:To easily adjust the direction of the main axis of an optical fiber by providing a ferrule fixing part which fixes a ferrule, an optical fiber fixing part which fixes the optical fiber and a turning member which mounts the optical fiber fixing part. CONSTITUTION:The optical fiber fixing part 3 is mounted to the turning member 4 and can rotate optical fiber 5 around its axis and, therefore, the direction of the main axis of the optical fiber 5 can be set in a prescribed direction by rotating the fiber while observing the end face of the optical fiber 5 projecting from the end face of, for example, the ferrule 2 with a microscope. The ferrule fitting part is held by a V-groove 1f and a press plate 1b and a key 1d is engaged with a keyway 2c, by which the ferrule is positioned with respect to the angle around the axis thereof. The ferrule is mounted in the specified direction in spite of the presence of a tolerance size in the width of the keyway 2c by tapering the front end of the key 1d and using a spring 1e.

IPC: F16C13/00
Filed: 1987-03-12
Abstract: PURPOSE:To facilitate the matching of a shaft and a tube and consequently make it possible to omit the main part of a mold for molding the shaft by a method wherein the tube is molded and, after that, the shaft is molded by pouring synthetic resin, the melting point of which is lower than that of the tube, in the hollow part of the tube and finally the sliding surface of the shaft is released from the inner peripheral surface of the tube by cooling and contracting the shaft. CONSTITUTION:A tube 1 is made by molding synthetic resin having a comparatively a high melting point. A round bar-like male mold 8 is concentrically inserted in the hollow part 3 of the tube 1, which acts as a female mold. Both end parts of the hollow part 3 are blocked with other molds so as to form a cavity for molding a shaft. Synthetic resin melted with an extruder is poured in the cavity in order to mold a shaft 7. The poured synthetic resin cools, solidifies and contracts, resulting in releasing the outer peripheral sliding surface 9 of the shaft 7 from the inner peripheral surface 4 of the tube 1. By pulling out the male mold 8 and removing the other molds, the molding of the shaft 7 completes. The synthetic resin used as the molding material of the shaft 7 has the melting point lower than the thermal deformation temperature of the tube 1. Accordingly, the matching of the shaft and the tube is easy, resulting in allowing to manufacture a highly accurate roller.

Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To obtain ferritic and austenitic stainless steel in which fur forming rate of σ phase as brittle phases is slow and suitable for a member to be used at a high temp. for a long time by limiting the concn. of Al and the concn. of Si as impurities to specified value. SOLUTION: The concns. of impurities in a ferritic and austenitic stainless steel as the material for apparatus to be used at a high temp. for a long time or the like are reduced to practicable degrees on an industrial level to limit the concn. of Al to <=50wt.ppm and that of Si to <=400wt.ppm. By selectively reducing this impurities, the forming rate of σ phases as brittle phases to be formed in the stainless steel in the use for a long time is delayed. In this way, the fracture of the apparatus to be used us prevented to secure its reliability and to prevent the reduction of the efficiency of the whole body of the plant.  Since the temp. of the using environment of high temp. apparatus such as a boiler reaches that in which σphases are easy to form, in the case the forming rate of σphases is made, e.g. half, its using enabling period is made double, and the cost to be required is made half.

Title: Charge pump circuit
Inventor: HAMURA YOSHIHIRO
IPC: H03D13/00
Filed: 1978-05-18
Abstract: PURPOSE:To connect the transistor Tr circuits of the same step number to both the charge and discharge signals and thus to eliminate the timing shift between the both signals for the charge pump circuit which is used to the PLL circuit. CONSTITUTION:Charge signals AA and AB are connected to the LPF via level conversion circuit 31 (NPN-type) and then 1st differential amplifier 32 (PNP- type); while discharge signals BA and BB are connected to the LPF via buffer circuit 33 (PNP-type) and then 2nd differential amplifier 34 (NPN-type) respectively. Thus, both the charge and discharge signals pass through two units of the Tr circuit each, and accordingly almost no difference is caused for the transmission time up to the LPF. Thus, the phase difference can be decreased satisfactorily for both signals. Furthermore, the both signals feature the combinations of Tr's like NPN-type to PNP-type and PNP-type to NPN-type each, and thus almost no effect is given to the transmission time of both signals.
