Title: Method for mounting of semiconductor device
Inventor: SHINOZAKI EIJI
IPC: H01L23/36
Filed: 1984-08-16
Abstract: PURPOSE:To reduce the number of component parts needed as well as to cut down the manhours for assembling by a method wherein a rivet-like substance is passed through the penetrated holes of a semiconductor device and a radiator, and the semiconductor device is fixed to the radiator by crushing the tip of the rivet-like substance. CONSTITUTION:A rivet-like substance 7 is passed through the penetrated holes of a semiconductor device 1 and a dissipater 2. The rivet-like substance 7 is made of resin, and its thermal expansion coefficient is smaller than that of the dissipater 2. Then, the rivet-like substance 7 is crushed by heating while force is being applied to the semiconductor device 1 and the dissipater 2 in such a manner that they are tightly fixed. As a result, a part 8 which is heated up and crushed is formed, and the semiconductor device 1 is fixed to the dissipater 2. Also, the rivet-like substance 7 shrinks when it returns to the normal temperature, and this shrinkage generates the force with which the semiconductor device and the radiator 2 are tightly contacted.

Abstract: PROBLEM TO BE SOLVED: To inexpensively and stably concentrate and recover a plating solution by passing a diluted plating solution, produced by mixing a plating solution pressed out from a plated steel strip with a washing water after washing the steel strip, through a reverse osmosis membrane to separate water and to concentrate the plating solution. SOLUTION: The steel strip S is continuously plated in a plating cell 1 constituted of an electrode 2, an electroplating bath 7 or the like. The plating solution stuck to the plated steel strip is pressed out in the vicinity of the outlet side of the electroplating bath 7 with upper and lower rolls 3, 4 and the steel strip S is washed by jetting water from a cleaning spray 5 before the plating solution is dried. The pressed out plating solution and the washing solution are introduced into a cleaning vessel 6 and the diluted plating solution is concentrated and recovered in a plating solution recovering device 8 provided with the reverse osmosis membrane and is returned to the electroplating bath 7 through a returning device 9.  As a result, the concentration and recovery of the plating solution are economically performed without degrading the components or composition of the plating solution.

Title: Seat for automobile
Inventor: SUZUKI MASAHIRO
IPC: B60N2/90
Filed: 1988-07-12
Abstract: PURPOSE:To enable the prevention of the forward shift of a buttock part via a support in a case such as collision by providing a downward projected bead on a plate spring with the rear end thereof fitted to a frame front, and a downward projected stopper flange at both sides of a panel, and covering an entire top surface with a cushion pad. CONSTITUTION:When a passenger is seated on a reference position, his/her buttock part causes an S-type spring 2 and a cushion pad 7 to be flexible, thereby generating comfortable cushion quality. At the forward part of a seat, his/her thigh is supported with a plate spring 5 and the cushion pad 7. When the plate spring 3 is subjected to a load from the buttock part and a bead 4 comes so flexible as to be in contact with a frame 1, the reaction force of the plate spring 3 comes forward of the bead 4 and it becomes possible to support the thigh on rather hard cushion matching the hardness of the buttock part. At the time of collision, the forward shift of the buttock part generates a high load on the forward part of the seat, and a panel 5 becomes flexible so downward as to cause the contact of a stopper flange 6 with the frame 1. In addition, even when the flange 6 comes in contact with the frame 1, no further sinking occurs due to the front rise of the panel 5 and the further forward shift of the buttock part can be prevented.

Title: Video tape recorder
Inventor: ISHIODORI MAKOTO
IPC: H04N5/7826
Filed: 1979-12-27
Abstract: PURPOSE:To prevent beat disturbance to video signal despite proximity disposition of recording, playback and erasing heads by differentiating the FM-modulated luminance signal to be recorded to erasing current for video tracks and supplying this to the erasing head. CONSTITUTION:A differentiating circuit 30 is provided to the post-stage of a high- pass filter 20, and the FM-modulated luminance signal or the signal obtained by the high-pass filtration of this signal is differetiated and is supplied to an erasing head 3 through a rotary erasing amplifier 30. The frequency characteristics of the circuit 30 are made into such characteristics in which the cutoff frequency is made to the frequency higher than the white peak of the video signal S. Hence, the low- band components are lowered and removed roughly at 6dB/oct and only the high- band components are filtered by the circuit 30. The recorder is so constituted that the differentiated waveform of such characteristics is supplied to the head 3 through the amplifier 31. Thereby, the occurrence of beat disturbance to the video signal owing to fog is prevented despite the proximity disposition of a recording-playback head 2 and the head 3.

IPC: G06F15/16
Filed: 1988-07-11
Abstract: PURPOSE:To reduce the time required for the operation management of a slave processing unit by providing a rough information request means and a detailed information request means to a master processing unit. CONSTITUTION:The master processing unit 2 gives a command of transferring the rough management information from the 4th address space 7 to the 2nd address space 8 to a transfer means 8 from its rough information request means 9 and stores the rough management information in the 2nd address space 5 to manage a slave processing unit. Thus, the rough management means 10 based on the rough management information grasps the operating state of the slave processing unit 1, and if the rough management information represents the occurrence of an important operating state, a detailed information request means 11 requests it to the transfer means 8 that the detailed management information stored in the 3rd address space 6 is transferred to the 1st address space 4. Thus, only when the operating state of the slave processing unit 1 has to be grasped truly, since the master processor 2 makes access to the detailed management information, the load required for the management is relieved.
