Abstract: PURPOSE:To facilitate assembly and to reduce the size of a module by providing a two-directional pressing mechanism to a lid which covers a photoelectric conversion device storage chamber and holding a device stably at a position where it is aligned with the optical axis of an optical fiber. CONSTITUTION:The photoelectric conversion device A is inserted into the device storage chamber 2 and the lid 10 is made to cover it until a claw 8 is locked in an opening 16. Then the device A is pressed against a bottom wall 5 and a front wall 4 by the pressure part 15 of the upper wall of the lid 10 and the pressure part 15 of the rear wall and held where it is aligned with the optical axis of the optical fiber. Thus, the lid 10 is fitted to apply a fixing force to the device A and the optical axis alignment is performed at the same time. Four surfaces of the device A are protected by the upper wall and side wall of the lid 10 from a disturbing electromagnetic wave, so an electromagnetic shield layer is not necessary. Consequently, the assembly of the module is facilitated and its size is reducible.

Title: Magnetic recording medium
Inventor: MIYOSHI TAKAHITO
IPC: G11B5/714
Filed: 1985-01-17
Abstract: PURPOSE:To obtain a magnetic recording medium having an excellent electromagnetic conversion characteristic and good running durability by incorporating inorg. particles having >=5 Mohs' hardness into a magnetic layer contg. pulverous ferromagnetic powder having >=42m<2>/g specific surface area. CONSTITUTION:The inorg. particles of >=5 Mohs' hardness are incorporated into the magnetic layer contg. the ferromagnetic metallic powder having >=42m<2>/g specific surface area. At least 90wt% of the inorg. particles consist of the particles having 0.1-0.6mum particle size and 51-85wt% thereof consists of the particles having <0.3mum particle size. The balance consists of the particles having >=0.3mum particle size. The magnetic recording medium having the intended high electromagnetic conversion characteristic is hardly obtd. if the specific surface area of the pulverous ferromagnetic powder is smaller than 42m<2>/g. The inorg. particles are likely to dislodge from the magnetic layer and since the head has hardly a polishing effect, the head clogging is liable to arise if such relatively soft inorg. particles having the Mohs' hardness lower than 5 are used.

IPC: B29C45/13
Filed: 1988-01-19
Abstract: PURPOSE:To simplify structure of a mold, to get rid of loss of a resin and to attempt to reduce manufacturing cost, by carrying out injection of a molten resin in two stages, i.e., the primary stage and secondary stage and forming a part of a thin thickness between the first and the second injections by forwarding an abrasive block.

At the same time, a piston of an oil pressure cylinder 3 is projected and a block 13 is thereby forwarded in the cavity 14. While the resin B existing on the front of the block 13 is pushed out around the block 13, the block 13 is abrasively forwarded to a position at which a thin part of a specified thickness is formed between a roof face 15 of the block 13 and a bottom face of the cavity 14. At the same time, the injection rod 24 is forwarded, the molten resin B is injected secondarily in the cavity 14. After a gate part 18 is sealed, an injection apparatus 2 is taken off and after the resin B in the cavity 14 is cooled and solidified, the mold is opened and a molded item is taken out.

Filed: 1980-01-26
Abstract: PURPOSE:To eliminate damage of the corner of ceramic membrane units or initiation of cracks in these units and thereby to raise up the rate of acceptance of products by grinding the end faces of ceramic units by means of collision against the inner wall of a ring-shaped grinding element. CONSTITUTION:When ceramic membrane units 4 in an appropriate number are put into a ring-shaped grinding element 2 and a vibrator is turned on, these units are energized into linear reciprocation by swing motion of the oscillator plate 1. They slide on a plastic sheet 5 to collide against the inner wall of the grinder 2 or against one another repeatedly. At this time, only end faces of the units 4 are ground through collision or frictional contact, and each end face will be thus given a little round convex owing to influence of the vibrations.

Abstract: PURPOSE:To correctly originate a call even at the time of extending a selecting number of call originating information by registering call originating information before the change and that after the change and using call originating information after the change in the case of coincidence between the number of digits of a prescribed part of input call originating information and that before the change. CONSTITUTION:When the telephone number of a destination station, the number of digits of a local office number after the change, the number of an added digit, the addition position of the number before the change, etc., accompanied with the change of the number of digits of the local office number are inputted from an operation panel 7, contents of a required area in a RAM 4 are updated to register call originating information after the change and a part of that before the change. When the number of digits of the local office number for call originating coincides with the number of digits registered in the RAM 4, a CPU 2 discriminates that the call is originated with information before the change, and the call is originated with call originating information after the change based on registered information of the RAM 4. By this constitution, the call is always correctly originated even at the time of extending the selecting number of call originating information.

Abstract: PURPOSE:To make it possible to keep corrugated fins in contact with a tube irrespective of manufacturing error in an vertical jig for assembling by forming said corrugated fins in such a manner that the height of fins on both sides in their width direction may be greater than the other parts. CONSTITUTION:Corrugated fins 7 are formed in such a manner that the height on both ends is greater than the height of other parts. When there is no manufacturing error of a vertical jig 5b, the corrugated fins 7 are compressed up to the other height in the width direction. If the aforesaid error thus produced is in minus, the corrugated fins 7 are compressed in conformity with the error, exceeding the height of the other parts so that the corrugated fins 7 may deep contact with a tube 1. When the aforesaid error is in plus, the corrugated fins 7 on both ends are compressed with the vertical jig 5b so that they may be kept in contact with the tube 1. In other words, the corrugated fins 7 keep contact with the tube 1 irrespective of the manufacturing error of the vertical jig 5b, thereby integrating both in one piece.
