Title: Miniaturized flow control element
Inventor: YANAGISAWA KEIICHI
IPC: F16K31/06
Filed: 1990-09-26
Abstract: PURPOSE:To obtain a high accurate and miniaturized flow control element which can play a role of a stop valve and has sufficient long life by forming a hole, on the periphery of which the conical magnetic substance on a leaf spring structure abut when a coil is energized by means of current a fixed value or more. CONSTITUTION:In a miniaturized flow control element, the center part of the magnetic film 12 on a silicon substrate 11 plays a role of leaf spring. As a result, when direct current of given value is applied to a coil, a magnetized minute conical magnetic substance 22 is attracted to a thin magnetic film 17 and thick magnetic film 19 to close a minute hole 18 thus constituting a stop valve. In the case where current energizing the coil is a constant value, an upper part of the conical substance is inserted into a minute hole 18 to reduce the practical area of the minute hole 18 thus making a valve to control flow rate. When the current is removed, the minute hole 18 is opened returning to the original state. A titled miniaturized flow control element play a role of a valve which can supply gas or fluid of minute quantity and a fixed quantity or a stop valve which can continuously supply or stop gas or fluid.

Title: Controller of continuously variable transmission
Inventor: IMAIDA MAKOTO
IPC: F16H61/08
Filed: 1993-09-16
Abstract: PURPOSE:To increase the torque of a torque converter during rapid shift-down. CONSTITUTION:When rapid shift-down is required, the speed change operation of a continuously variable transmission mechanism is delayed throughout the release time of a lock-up clutch 12d. Since the change in the rotation speed in the side of the turbine shaft 13 of a torque converter 12 is delayed in relation to the change in the rotation speed of an engine, the speed ratio of the torque converter 12 is generated, and the torque is thus increased.

Title: Optical information recording member
Inventor: ONO EIJI
IPC: G11B7/2531
Filed: 1990-09-25
Abstract: PURPOSE:To improve recording and erasing sensitivity by alternately laminating, plural times, optically active layers and layers for accelerating conversion to the amorphous state which commit of dielectric material to constitute the above recording member and specifying the layer thickness of the optically active layers to a prescribed value or below. CONSTITUTION:A sample is prepd. by forming a dielectric layer 5, a recording layer 2 and a dielectric layer 5 in this order on a substrate 1. The recording layer 2 is constituted by specifying the total layer thickness of the optically active layers 3 to 80nm, dividing the layers to N layers and forming the layers for accelerating conversion to the amorphous state to the same thickness as the thickness of the optically active layers at this time. N is changed in a range from 1 to 80. Consequently, the recording sensitivity is evidently improved if the optically active layers are formed to <= 10nm. The sensitivity is particularly greatly improved at >= 2nm and <= 8nm. The power for conversion to the amorphous state is decreased in this way and, therefore, the recording sensitivity is improved.

Title: I/o unit
Inventor: TAKERA JOJI
IPC: G05B19/05
Filed: 1990-09-25
Abstract: PURPOSE:To reduce the entire size of a programmable controller by using a single I/O unit in common to two external devices. CONSTITUTION:When a mode changeover switch SW2 is turned on in an input mode, a base current is supplied to a transistor TR Q1. Thus the Q1 is turned on. This fact is reported to a mode identification terminal DRDY through a photocoupler PC1. The terminal DRDY outputs a low-level signal to show the input mode. Therefore a controller main body 1 can judge that an I/O unit 2 is operating in an input mode. Then the SW2 is turned off in an output mode. Under such conditions, the DRDY is set at a high level. Thus the main body 1 can judge that the unit 2 is kept in an output mode. In such a way, a single I/O unit is used in common to two external devices and the entire size of a programmable controller can be reduced.
