Abstract: PROBLEM TO BE SOLVED: To relieve mechanical stresses and facilitate mounting of solder balls by installing a semiconductor element connected with a conductor wiring, conductive material with which aperture holes are filled to be smaller than the thickness of an insulating film, and the solder balls connecting the conductive material and a mother board. SOLUTION: Aperture holes are formed in an insulating film 2, and a conductor wiring 3 is formed on the insulating film 2. The conductor wiring 3 and an electrode of a semiconductor element 1 are electrically and mechanically connected, and sealing is performed with a sealing resin 4 for protecting the connecting part of the conductor wiring 2 and the electrode. The aperture hole of the insulating film 2 is filled with a conductive material 5 to be smaller then the thickness of the insulating film 2. Solder balls 6 are mounted on the conductive material 5, and a semiconductor device and a mother board 7 are connected by reflow after the solder balls 6 have been aligned with a pattern of the mother board 7. As a result, the gap between the insulating film 2 and the mother board 7 can be held wide, and mechanical stresses or the like can be relaxed.

Title: Motor drive unit
Inventor: MASHITA YUKIO
IPC: G03B17/00
Filed: 1978-10-11
Abstract: PURPOSE: To perform stable operation through changing-over of small currents with a simple mechanism and circuit constitution by providing a winding drive circuit and a rewinding drive circuit and letting braking action be effected at the operation stopping by one of thses circuits.  
     CONSTITUTION: When, for example, in high speed continuous photographing, a switch S 12 M is turned on by operation of the release, the transistor T 2  of a motor drive circuit 7 is turned on by way of the H contact of a switch S 6  and resistance R 15 , hence the transistor T 1  goes on to let a motor 3 run. At the time when the switch S 16  goes OFF upon completion of winding, the transistors T 2 , T 1  of the motor drive circuit 7 go OFF. Since this causes the motor 3 to be operated as a generator by inertia force, a potential difference is produced between the emitter and base of the transistor T 3  of a motor braking circuit 8. Then the transistor T 3  goes ON to short between the terminals of the motor 3, thereby applying brake. In this way, the stable operation may be accomplished by small currents with the simple mechanism and constitution.

Filed: 1982-07-21
Abstract: PURPOSE:To improve display precision in low-speed rotation, by inputting a pulse signal of frequecy propotional to the engine speed to a microcomputer, and calculating the rotating speed on the basis of the signal. CONSTITUTION:The microcomputer 3 inputs the pulse signal of frequency proportional to the engine speed from a number of revolution detector 2 which detects the engine speed, and calculates the engine speed on the basis of the signal to find the engine speed per interval of bars according to the engine speed, deciding on the number of bars to be displayed. Then, corresponding light emitting diodes are turned on to perform bar display. Consequently, the engine speed per interval of bars in low-speed rotation becomes less than that in high-speed rotation to improve the display precision in the low-speed rotation.
