Title: Joining member
Inventor: MIYAZAKI NOBUHIKO
IPC: H01L23/40
Filed: 1993-03-18
Abstract: PURPOSE:To provide a joining member which joins a heating part to a heat radiative member in a shot time, provides favorable thermal conduction between them, and is easy to handle. CONSTITUTION:A joining member 1 is obtained by forming thermoplastic resin containing thermal conductive grains 2 into a sheet. The thermoplastic resin is based on rubber thermoplastic resin, such as butylene rubber and styrene. The thermal conductive grains 2, made of alloy composed of aluminum, alumina and magnesium, are excellent in thermal conductivity. Letting the thickness of the joining member 1 be Ta and letting the size of the thermal conductive grains 2 be Tb, Ta should be larger than Tb. A heating part and a heat radiative member are bonded together by thermo-compression with the joining member 1 in-between. This compresses the thickness Ta, which brings the thermal conductive grains 2 in contact with both of the heating part and the heat radiative member.

Filed: 1979-05-16
Abstract: PURPOSE:To enable common use of plating mask by partly plating only special boundary inside the inner frame in a lead frame for a semiconductor partly plated at a die stage and metallic fine wire connector. CONSTITUTION:When plating the die stage 4 of a lead frame for a resin sealed semiconductor device having 16 external lead wires 5 and the die stage to the metallic fine wire connector 7, a plurality of internal lead wires 1 in parallel inside the inner frame 2 are divided into plated wires and not-plated wires via a boundary lines 11 perpendicularly crossed with the wires and plated.

Title: Fluctuating actuator
Inventor: MITSUYA YASUNAGA
IPC: G11B21/02
Filed: 1980-05-08
Abstract: PURPOSE:To prevent damaging a magnetic disc by providing a lever for mounting a driving coil on the side opposite from the mounting position of a magnetic head to an fluctuating shaft, and specifying the fluctuation range of a fluctuating body by means of the pawl on the lever and the stopper on the stationary side. CONSTITUTION:The positioning of a magnetic head is accomplished by controlling the current to be flowed to a driving coil 11 with the position information read with a servo head and when a feedback control system makes malfunction, an fluctuating shaft runs away, resulting in that the pawl 20 collides against the stopper. When it runs away and collides against the stopper, an fluctuating body 15 receives the reaction from the stopper 21, but since the stopper 21 positions near the center of inertia in the vertical direction of the body 15, the bending moment acting upon the body 15 is small and the displacement in the vertical direction of an arm 6 hardly occurs. The occurrence chance of the vibration in the vertical direction is also less because the symmetry in the vertical direction of the body 15 is high.
