Title: Metal mold apparatus for sealing semiconductor element with resin
Inventor: TONE YOSHIMORI
IPC: B29C45/27
Filed: 1987-03-17
Abstract: PURPOSE:To obtain a metal mold apparatus, in which sealing resin is pressed into both cavities evenly, regardless of the density of inner leads, the sizes of die pads, the thickness of a package or the like, by providing resin feeding gates, which are communicated to both cavities in top and bottom forces. CONSTITUTION:When a plunger 9 is lowered, a sealing resin 8 is simultaneously pressed into cavities 2 and 6 individually through runners 4a and 4b and resin feeding gates 5a and 5b. When the opening areas of the resin feeding gates 5a and 5b are made approximately equal at this time, the injecting speeds of the resin into the cavities 2 and 6 become approximately equal. The resin is not moved through the gaps between inner leads 10 and the gaps between the inner leads and die pad 12. Or the resin is hardly moved. Thus the resin is simultaneously pressed into the cavities 2 and 6 at the approximately same speed. The resin feeding gates are communicated to the respective cavities in the top and bottom forces in this very simple structure. Thus, the pressing of the sealing resin into the cavities of the top and bottom forces is made even, and an excellent molded body can be obtained.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the process of heating crystallization after deposition and to reduce a cost by depositing the recording layer of an optical recording medium with which the recording and reproducing of information are executed by the phase transition between amorphous phase and a crystalline phase by sputtering while supplying electric power of a high frequency to a substrate. SOLUTION: At the time of depositing the recording layer by sputtering, the recording layer is deposited as a crystalline layer by executing deposition while supplying the electric power of the high frequency to the substrate. A method for sputtering the recording layer target is preferably high frequency sputtering. The electric power to be applied on the substrate is preferably >=1 to <=30% of the electric power. If the electric power is >=1 to <=10%, the crystallization is insufficient in some cases depending upon the compsn. of the recording layer and the electric power of >=10% is further preferable. As a result, the need for heating and crystallizing the recording layer by a laser, etc., after the deposition stage is eliminated and the production cost of the phase transition recording medium is reduced.

IPC: H01F13/00
Filed: 1993-03-23
Abstract: PURPOSE:To provide an efficient magnetizer for by causing producing a permanent magnet by using substantially all magnetic fluxes generated when current is supplied to its coil. CONSTITUTION:This equipment is provided with a permanent magnet 1, a plurality of magnetic poles 2 which are so located as to face the permanent magnet 1, coils 3 which are wound round the magnetic poles 2, and non-magnetic conductors 9 which are located near the permanent magnet 1 and between the magnetic poles. When specified current is applied to the coils 3, magnetic fluxes are generated. The generated magnetic fluxes run along the magnetic pole 2 and go through a space between the magnetic pole 2 and the permanent magnet 1 and then pass through the permanent magnet 1 and finally go to the adjacent magnetic pole 2. At that time, eddy current is caused to flow in the non-magnetic conductor 9 located between the adjacent magnetic poles 2 due to the hourly variable magnetic fluxes. Magnetic fluxes generated by this eddy current pushes the magnetic fluxes leaking to the adjacent magnetic pole 2 back to the permanent magnet 1. This is why the permanent magnet 1 is magnetized efficiently.
