Title: Heat plate fixing unit
Inventor: DOI YUJI
IPC: H05K7/20
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To enhance heat dissipation effect by providing a plurality of eave-like protrusions and resilient pawls on the body chassis fixed with a heat source member and securing the heat plate tightly to a heating member, thereby enhancing stability of adhesion between the heat plate and the heat source member and suppressing fluctuation. SOLUTION: A heat source member, i.e., a motor 2, is secured at first to a specified position of a body chassis 1 by means of screws 6. A heat plate 3 is then inserted in the direction of the body chassis 1 by sliding a recess 3a thereof between the body chassis 1 and an eave-like protrusion 4 provided on the vertical surface thereof. The recess 3a of the heat plate 3 is engaged with a resilient pawl 5 provided on the body chassis 1 and the resilient pawl 5 is deformed resiliently by a clamping force being generated between the recess 3a of the heat plate 3 and the eave-like protrusion 4. A repulsion force acts to press the end part of the recess 3a engaged with an inclining face 5c at the forward end of the resilient pawl 5 in the direction of the motor 2, thus sustaining the heat plate 3 and the body chassis 1 in tight contact state.

Title: Video signal processor
Inventor: NAKA KAZUTAKA
IPC: H04N5/956
Filed: 1992-04-16
Abstract: PURPOSE:To provide a video signal processor convertable to completely asynchronous video signals for field units by a signal converting processor to convert the video signals to the video signals of different form or the like. CONSTITUTION:Using a field memory 6 which enables read/write operation asynchronously and a delay circuit 7 of several lines, read reset processing is delayed when write reset processing and the read reset processing get close within a prescribed time, and the competition between read and write is prevented. Normally, data from the memory 6 is delayed and outputted, at the time of read reset delay, data is not delayed and is outputted. Thus, the conversion to the desired completely asynchronous video signals can be performed with the data neither too much nor too little completely for the field units. The influences of time base fluctuation such as the jitter and the skew of input video signals or the like can be removed. Mulfunction can be prevented by making the judgement of the read/write competition have hysterisis.

IPC: F02D9/02
Filed: 1994-05-10
Abstract: PURPOSE:To maintain favorable accuracy despite variations in accuracy from one unit to another at the shipment of products and deterioration due to long time use, by learning and correcting current values stored in a storing means based on the amount of stepping motor drive detected using a drive amount detecting means. CONSTITUTION:When an internal combustion engine is idling, CPU 1 controls the opening of a throttle valve 10, a drive amount detecting means, so that the number of rotations of the engine will reach a target value. When a driving command is issued by the throttle valve 10, CPU 1 reads a current value from RAM 14, a storing means, and commands it. The current command value is converted from digital into analog by a digital-to-analog converter 2. A motor current corresponding to the current command value is fed from a power supply 12 for stepping motors to each phase of a stepping motor 6. The stepping motor 6 is thereby driven to a desired step position. This maintains favorable accuracy despite variations in accuracy from one unit from another of products, and the deterioration due to long time use.

Filed: 1978-08-09
Abstract: PURPOSE: To prevent blowholes from arising in a brazing material layer by keeping temperature distribution of a semiconductor element even or higher at the outer perimeter than the center before and after brazing.  
     CONSTITUTION: When inserting that for which support plate 3, brazing material 2 and Si substrate 1 are laminated in a heating furnace 6, a heater 9 is installed in a base 8 for the support plate 3 or in the interior of the furnace somewhere, and a dent 10 smaller than the support plate 3 diametrally is prepared on the face to place. Heat generated by the heater 9 therefore keeps the center of support plate 3 at low temperature and the outer perimeter at high temperature. According to this temperature distribution, a solidification of the brazing material 2 goes from the center gradually to the outer perimeter to drive out the gas. No blowhole will arise consequently, and thus electric and thermal resistance characteristics of the element are improved.
