Title: Ignition unit of internal-combustion engine
Inventor: MASUNO TAKEYOSHI
IPC: F02P7/067
Filed: 1982-03-10
Abstract: PURPOSE:To detect a ignition point without making any contact and to adjust it easily by varying the oscillating condition in a resonance circuit provided with a coil of a detecting head by moving a movable magnetic metal piece placed facing the detecting head. CONSTITUTION:A detecting head 3 consisting of a core 3a and a coil 3b is fixed in place, facing plurality of leg parts 2a of a rotatable magnetic metal piece 2 of a rotary shaft 1 that rotates synchronously with an engine, in order to form an oscillating circuit being combined with a condenser 4. Thus variation in the oscillating condition due to an active circuit 5 is detected by a ignition signal generation circuit 6 in order to output an ignition signal which is input later into an ignition circuit 7. At the other end of the coil 3b, a movable magnetic metal piece 12 is placed, and as the distance between the coil end and the metal piece becomes greater, the envelope of the oscillation amplitude in direction A becomes larger. Accordingly, regarding pulse-form ignition signal 13 that is obtaind by comparing the envelope with specified voltage Vs in the ignition signal generating circuit 6, the ignition points, at the negative-going time of the pulse, is more advanced as the distance becomes smaller. Thus, the ignition point can be adjusted easily.

Title: Decoder for moving picture signal
Inventor: KOSHIBA SATOSHI
IPC: H04N19/152
Filed: 1989-02-17
Abstract: PURPOSE:To prevent the quality of a reproduced picture at the receiver side from being deteriorated and to compress the quantity of sent information by throwing away an AC coefficient component of an orthogonal transformation coefficient, and coding a quantization level of a DC coefficient component when the quantity of a code of a preceding block is comparatively much. CONSTITUTION:An AC component throw-away circuit 13 is provided, which outputs a level quantized by a quantizer 12 as it is, or rounds of a quantization level of an AC coefficient component to output the result as a quantization level '0'. When the quantity of the preceding block is comparatively much, since the AC coefficient component of the orthogonal transformation coefficient is rounded off, the quantity of sent information is able to be compressed and since no DC coefficient component is rounded off, the quality of the reproduced picture at the receiver side is not deteriorated.

Title: Plating method and apparatus
Inventor: TABATA AKIRA
IPC: H01L21/60
Filed: 1989-02-17
Abstract: PURPOSE:To form a uniform plating layer and to enhance the yield of production by reducing the pressure of a space on a plating soln. and upwardly separating bubbles generated on the surface of a substrate. CONSTITUTION:The pressure of a space 14 on a plating soln. 4 in a plating vessel 2 is reduced to about 20-100Torr by a vacuum pump 16 and a prescribed voltage is impressed between a wafer 6 as a substrate and an anode plate 8 to electroplate the exposed barrier metal of the wafer 6. During this plating, bubbles of oxygen are generated from the surface of the anode plate 8 and bubbles of hydrogen from the surface of the wafer 6 to be plated on the cathode 10 side. Since the space 14 on the plating soln. 4 is kept under the reduced pressure, the bubbles readily leave the surfaces and rise by the pressure difference. The separation of the bubbles of hydrogen is accelerated by setting an ultrasonic oscillator 20 and applying ultrasonic vibration to the bubbles on the surface of the wafer 6 to be plated.

Abstract: PURPOSE:To stabilize laminating, and to avoid an inter-layer short circuit by previously tapering the sectional shapes of flat-type conductors on the bending side on winding when an electromagnet coil is manufactured by winding and laminating the flat-type conductors. CONSTITUTION:The sectional shapes of flat-type conductors 3 wound and laminated on an electromagnet core are not equalized, the height of the conductors is lowered only by size corresponding to the quantity of bending and deformation only on the bending inside, and the conductors are formed to a tapered shape.
