Abstract: A disc chucking mechanism includes a turn table 3 on which a disc 19 with a center hole 20 is located, a chucking magnet 10 for magnetically attracting a center hub 21 of the disc 19 to it, and a magnet yoke 60. The magnet yoke 60 includes a ring-like member which is inserted between the turn table 3 and the chucking magnet 10, engaging portions 62 which are extended from the ring-like member of the magnet yoke toward the turn table 3, and brought into engagement with the turn table, and magnet engaging portions 61 which are extended in the direction opposite to the bending direction of the engaging portions 62, and urgingly fix the chucking magnet 10.

Abstract: After a coil 24 is wound through an open slot 26 which forms a sufficient space for the winding operation of an armature core 10, a magnetic member 34 is inserted and mounted into the open slot 26 and is then engaged with and fixed to the umbrella portions 20 of the armature core 10. A gap 36 formed in the central portion of the open slot 26 operates to narrow a gap between the magnetic poles of mutually adjoining salient poles 16, which reduces not only the generation of cogging phenomena and vibrations but also variations in quality between products, that is, the armature cores 10 produced.

Abstract: In the stage of winding a drive coil (17) on salient poles (114) in the assembling of a motor (1), the opening width of an armature core (11) is wide enough to allow easy and proper winding of the drive coil (17). After the winding of the drive coil (17), opening-width adjusting members (50A) are put within open slots (100), to thereby reduce the opening width of the armature core (11) at the flux gathering parts (54A) and (55A) of the opening-width adjusting member (50A). The opening-width adjusting member (50A) is positioned and fixed, by its elasticity, within each open slot.

The head portion of the rail has a uniform bainite structure. The Vickers hardness at any position of the head top portion and the head corner portion is 240 to 400 Hv. A rail of high toughness and high wear resistance, consisting essentially of 0.2 to 0.5 wt. % of C, 0.1 to 2.0 wt. % of Si, 1.0 to 3.0 wt. % of Mn, 0.035 wt. % or less of P, 0.035 wt. % or less of S, 0.3 to 4.0 wt. % of Cr, and the balance being iron and inevitable impurities.

Abstract: A high-strength bainitic steel rail having an excellent damage resistance property, essentially consists of 0.2 to 0.5 wt % of C, 0.1 to 2.0 wt % of Si, 0.3 to 4.0 wt % of Mn, 0.035 wt % or less of P, 0.035 wt % of S, and 0.3 to 4.0 wt % of Cr, a balance being Fe, and having a micro structure made of a bainitic structure.

Abstract: A work mounting apparatus has a head drum rotated in one direction, work heads arranged on the outer periphery of the drum, each work head including a suction nozzle projecting from the work head toward a circular travel path, for moving along the travel path while keeping a fixed orientation and repeating a cycloidal motion during rotation of the head drum, a work feeder arranged on the travel path, and a movable table arranged on the travel path at a distance from the work feeder, for receiving thereon a printed board, wherein the suction nozzle of each work head sucks up a work from the work feeder and releases the sucked work at a desired release position on the travel path. The movable table is moved along a line intersecting the travel path, whereby a target point on the printed board, at which the work is to be mounted, is brought to the release position on the travel path, in cooperation with cycle control of the cycloidal motion of the work head.

Abstract: A cigarette stacking method is disclosed. It uses a stacking drum and a plurality of arranging drums near to its outer periphery, establishes different positions in the axial direction for cigarette pieces arranged by the arranging drums, stacks cirgarette groups in several layers in such a manner as to extend the end portions of the cigarette pieces successively in the axial direction on the stacking drum, and absorbs and maintains the cigarette pieces of each layer. A cigarette stacking apparatus is also disclosed.

Abstract: An apparatus for compressing cigarettes comprises a compression pocket having opposite open ends which comprises a pair of L-shaped compression members which are disposed in an opposite manner. Each member includes short and long segments which extend in an axial direction of a continuously rotatable drum, one of the members being movable in a tangential direction of the outer circumference of the drum, the other member being movable in a direction at an desired angle relative to said tangential direction. The apparatus also includes a device for moving the pair of L-shaped compression members in opposite directions using a rack and pinion combination system.

Abstract: A cigarette arranging apparatus is disclosed. It has an arranging drum including a plurality of arcuate grooves arranged in its periphery, the grooves being extended in the axial direction and intimately contacted each other in the circumferential direction, and a plurality of cigarette receiving rollers near to the upper outer periphery of the arranging drum. The number of the cigarette receiving rollers corresponds to that of the arcuate grooves. The cigarette receiving rollers are arranged each to receive one piece of cigarette out of the plurality of cigarette pieces. The arranging drum and the cigarette receiving rollers are rotated in the opposite directions each other. The rollers are arranged to send cigarette pieces into the grooves successively from the forward grooves till the backward grooves without changing the motion speed to arrange cigarette groups intimately contacted each other.

Abstract: A protective apparatus for a pick-up tube of a television camera includes a photo-electric conversion element for detecting the intensity or amount of light incident on the pick-up tube. A shutter or reflector is disposed in the optical or light path from the outside of a housing for the pick-up tube to its target screen and is rotated by a drive device to be capable of preventing an external light from being incident on the target screen of the pick-up tube when the intensity of the external light detected by the photo-electric conversion element exceeds a predetermined value. A control circuit is provided which will operate the drive device to rotate the shutter or reflector to such a state where the external light is prevented from being incident on the target screen of the pick-up tube when the intensity of the external light detected by the photo-electric conversion element exceeds the predetermined value.

Abstract: A remote station provided with a television camera and coupled to master station of an inter communication system is disclosed. The housing of the remote station includes at a least front panel and a window is formed through the front panel at its upper portion. An adaptor lens is engaged with the window for introducing the light from an object to be picked up at a wide angle into the housing and a pick-up tube of a television camera is disposed within the housing. A reflector is disposed within the housing between the adaptor lens and the pick-up tube so as to reflect the light from the object thereon and project thus reflected light on the pick-up tube.
