Title: Automatic light level control system
Inventor: SHIMIZU HIROTOSHI
IPC: G02F1/11
Filed: 1981-02-10
Abstract: PURPOSE:To automatically adjust the output level of a laser beam by changing the diffraction efficiency into analog of a light modulation element according to terminal voltage of a capacitor which is varied, while detecting the range outside the upper and lower limits of the printing exposure with the laser beam. CONSTITUTION:After a laser beam modulated with a light modultion element 2 is reflected on a rotary mirror 3, a part thereof is detected with a light detection circuit 4 and a signal corresponding to the level of the beam is output into upper/lower limit comparator circuits 9 and 10. When the signal value is below the lower limit, the circuit 9 provides a signal to a latch driver circuit 11 which generates an output '1'. Consequently, a transistor QA is turned on to charge a capacitor CA so that the control signals of a driving circuit 13 and an AOM driver 14 will be changed to increase the diffraction efficiency eta, causing an increase in the output P0.eta of the laser beam on a light receiving surface D. When the level of the beam is above the upper limit, the capacitor CA is discharged to reduce the value eta.

Title: Piston ring for two cycle reciprocating internal- combustion engine and method of producing same
Inventor: MITSUIDA HIROSHI
IPC: F16J9/00
Filed: 1984-02-06
Abstract: PURPOSE:To prevent a piston ring from springing-out by setting the surface pressure distribution of the piston ring to low surface pressure one in a port portion of the inside wall of a cylinder in a two cycle reciprocating internal combustion engine. CONSTITUTION:The surface distribution P(theta) of a piston ring maintained at the perfectly circular condition is assumed to be represented by P(theta)=A0+SIGMA[An-1cos (ntheta)]. The surface pressure shown by the piston portions corresponding to an exhaust port portion and a scavenging port portion is made smaller than the average surface pressure of the ring. Thus, the piston ring can be prevented from springing out of the exhaust and scavenging ports to be broken down.

Title: Rotary atomized electrostatic coating device
Inventor: MORISHITA HIKARI
IPC: F16C32/04
Filed: 1980-02-19
Abstract: PURPOSE: To rotate a spraying head at high speeds and improve the atomization of spray painting by supporting a rotating shaft by means of noncontact type radial bearings and a noncontact type magnetic thrust bearing.  
     CONSTITUTION: A rotating shaft 8 is supported by means of a magnetic thrust bearing consisting of runners 39, 40 and an annular plate 44, and a pair of tilting pad radial type air bearings 22, 23. In these air bearings 22, 23, air is drawn into the microclearnaces between a hollow cylindrical part 8a of the rotating shaft and the pads 24, 26, and the air is compressed by the wedging effect of this air, by which pressure is increased and the rotating shaft 8 is thereby supported. In the magnetic thrust bearing, the microclearances between the annular plate 44 and the runners 39, 40 are maintained by the repulsive force of a permanent magnet. Hence, said shaft 8 is supported in a noncontact state by way of the microair layer, and this makes possible fairly high-speed rotation.

Filed: 1982-02-08
Abstract: PURPOSE:To obtain a semiconductor device available to a high speed operation and a high density formation by a method wherein the thickness of a P-N junction depletion layer is changed by a gate electrode, and thus the tunnel current or the avalanche current flowing through the junction is controlled. CONSTITUTION:When the absolute value of the voltage of the gate electrode 5 is small, and the high density carrier region of an accumulation layer or an inversion layer is not formed on the surface of a substrate, a thick depletion layer is formed in the substrate 11 at the P-N<+> junction between the substrate 11 and a drain 14, and accordingly the current (drain current) between the source 12 and the drain 14 does not flow. When a sufficiently large negative voltage is impressed on the gate electrode 5 resulting in the formation of the hole accumulation layer on the surface of the substrate, the depletion layer for the most part does not expand, then the carrier can pass through the tunnel when the width becomes several ten Angstrom  or less, and the avalanche is caused when the field becomes 10<5>V/cm or more even with the depletion layer width over that, and accordingly the current flows between the source 12 and the drain 14.

Abstract: PURPOSE: To secure erasure neither by using any pad nor by increasing tension of a magnetic tape, by slanting the front surface of an erasing magnetic head formed in an arc shape from a gap circumference toward its outside by a certain angle to the center tangent of the front surface.  
     CONSTITUTION: A region where magnetic tape 4 running as shown by arrow A comes in contact with contact surface 1a of magnetic head 1 is expressed by L. Its front surface is formed being slanted from a point constant interval (e) away from gap 2 toward is outside by angle θ to center tangent (m) of front surface 1a of head 1. The figure shows the relation among distance (l) between gaps 2 and 3, contact surface L of contact surface 1a and contact pressure P 1 , and great contact pressure can be obtained. Contact pressure to the front surface on the gap-3 side is similarly increased.
