Title: Proportional pressure control solenoid valve under pulse width modulation control
Inventor: IKEBE HIROSHI
IPC: F16K31/06
Filed: 1982-03-18
Abstract: PURPOSE:To widen the range of control, by using a control mechanism provided separately from a DC on-off solenoid, to control the positional relation between a sheet and a valve poppet. CONSTITUTION:A plunger 15, which is combined with a DC on-off solenoid 13, is integrally coupled at the inner end with the end of the shaft 9 of a valve poppet 8 and provided with a flange 16 at the outer end. The DC on-off solenoid 13 functions to change the positional relation between the valve poppet 8 and a seat 11, depending on the action of a positioning solenoid 18. For that reason, the substantial thrust on the valve poppet 8 is increased despite the constant magnitude of electrical current to the solenoid 13 as the poppet nears the seat 11. The thrust is decreased as the valve poppet 8 moves away from the seat 11.

Title: Clamping method of lens for centering
Inventor: IDESAKA HIDEFUMI
IPC: B24B9/14
Filed: 1982-03-18
Abstract: PURPOSE:To enable to automatically centering-clamp by a method wherein an upper cup body  is forwarded under low pressure and at low speed while rotating toward the lens placed on a  lower cup body so as to clamp it between the cup bodies and, after being clamped, the upper  cup body is further pressed under high pressure. CONSTITUTION:When the lens 11 is placed on the lower cup body 5, the lens 11 is stuck to the  lower cup body 5 due to the negative pressure applied through a swivel joing 28. After that,  the upper cup body 6 is lowered while rotating by means of a DC motor 18 and a cylinder 9.  Now assuming that the lens 11 is placed eccentrically on the lower cup body 5, the edge of  the upper cup body 6 abuts the lens 11 at the uppermost point P and the pressing force of the  upper cup body 6 tends to shift the lens 11 in the direction of the center of the cup body and  the tangential force A causes to turn the lens 11 around the point Q. However, the thick part  S is prevented from passing through the edge and consequently the center of turning of the  lens 11 is shifted upward and finally the turning motion of the lens 11 is performed around  the point R. The tangential force A is continuously applied on the surface of the lens 11 due  to the rotatingly lowering of the upper cup body 6, resulting in bringing the optical axis of the lens 11 in alignment with the center axis of the cup body. At this instant, the DC motor  18 is stopped and then the lens 11 is tightly clamped between the cup bodies 5 and 6 by supplying high pressure oil into the cylinder 9.

Filed: 1988-02-26
Abstract: PURPOSE:To reduce the parasitic resistance of source and drain electrodes and obtain the high performance of this device, by providing an AlGaAs cap layer having a sufficiently large Al composition between a barrier layer and an n<+> type Ge gate layer and performing annealing at a high temperature. CONSTITUTION:An undoped GaAs channel layer 2 is formed on a semi-insulating GaAs substrate 1 and an undoped AlGaAs barrier layer 3 having an impurity concentration which is sufficiently low is formed on the foregoing channel layer. And an AlGaAs cap layer 4 having the impurity concentration which is sufficiently low is formed on the foregoing barrier layer. A gate layer 5 is formed by treating n<+> type Ge into a stripe like shape and a WSiX gate electrode 6 is formed by treating WSiX into the stripe like shape. Then, source and drain regions 7 as well as source and drain electrodes 8 which have n-typed both sides are formed. As low impurity-concentrated AlAs is used at the cap layer 4, a reaction which takes place between Ge and the cap layer 4 as well as the barrier layer 3 is suppressed. Thus, active annealing is performed at a high temperature.

Title: Recording and reproducing device

IPC: G11B19/14
Filed: 1985-03-06
Abstract: PURPOSE:To improve the positional precision of tracks very much by detecting the rotation angle and the moving position of a stepping motor and forming one of plural tracks in the position where the driving pattern of the stepping motor is a prescribed pattern. CONSTITUTION:The adjustment range of a rotation angle detector 17 is <=1/4 rotation of a stepping motor 1, and that of a head position detector 19 is <=2.5 track pitch, namely, about 1/20 of the head moving range if the head moving range is 49 track pitches, and detectors are adjusted easily. Since adjustment ranges are wide in this manner, mechanisms which amplify the rotation angle and the extent of movement for both detectors 17 and 19 are unnecessary, and detectors 17 and 19 are hardly the load of the stepping motor 13. Since a device is so constituted that fine adjustment is performed by the stepping motor after the time when prescribed signals are obtained from detectors 17 and 19, the positional precision of the track formed in the stop position is very high, and 1/2 head moving pitch is obtained.
