Filed: 1988-09-28
Abstract: PURPOSE:To obtain an electroconductive thin film having sufficiently high reflection preventing effect by providing at least one layer comprising a ZrO2 film contg. CaO or Y2O3 to a reflection preventing film. CONSTITUTION:A reflection preventing film 2 is formed using a ZrO2 film contg. CaO or Y2O3.

IPC: B66F3/08
Filed: 1987-09-28
Abstract: PURPOSE: To attain a smooth rotation even under an unpreferable condition by providing at least three ball bearing units to be engaged with a screw, and engaging one of them on the 180 deg.-opposite side to the others so as to support a nut structure to a screw shaft only by the engagement points of the ball bearing units. CONSTITUTION: At least three ball bearing units 4-6 to be engaged with a screw 2 are provided in such a manner that all the engagement points with the screw 2 are situated within the vertical working plane of a screw shaft 1. At least one ball bearing unit 5 is engaged on the 180 deg.-opposite side to the other two ball bearing units 4, 6, and a nut structure 3 is supported to the screw shaft 1 only by the engagement points of the ball bearing units 4-6. Consequently, the moment and force generated by the radial forces of the ball bearing units 4-6 are mutually canceled to dispense with a neck bearing for supporting the screw 2 itself on the screw shaft 1. Accordingly, this jack can be operated with an extremely small friction and vibration.

Filed: 1986-10-13
Abstract: PURPOSE:To obtain large-current ion beams of high quality by installing an ion deflecting part, in which an ion beam orbit is deflected, between an ion separating part and an ion implanting chamber and installing a scanning part for mobile scanning in the ion implanting chamber. CONSTITUTION:Ions generated in an ion source 1 are accelerated in an ion accelerating part 2 and made to enter an ion separating part 4 and separated into ion species with specific mass by a magnetic field in the ion separating part 4.

Title: Micro relay
Inventor: NAKAJIMA TAKUYA
IPC: H01H59/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a relay, securing initial gap required for insulation and enhanced in contact pressure without increasing the drive voltage by composing a movable board with a first moving piece cut out by forming a slit and a second moving piece formed in a first moving piece and less elastically deformable than the first movable piece and forming a moving contact on the lower surface of a second movable piece. SOLUTION: When electrostatic attraction is generated by applying a voltage between a fixed board 10 and a movable electrode 23, the movable electrode 23 which is easier to elastically deform than a second moving piece 27 is attracted to the fixed board 10 side and bent. Thereby, even after a moving contact 28 is lowered and abuts on fixed contacts 14b, 17b, the distance between the fixed board 10 and the movable electrode 23 is reduced, so that larger electrostatic attraction is generated between them. The movable electrode 23 further approaches the fixed board 10 and is attracted by the fixed board 10. As a result, the second moving piece 27 is bent to provide large contact pressure, and a signal is transmitted stably between signal wires 14a, 17a. Preferably, the movable electrode (first moving piece) is formed into a counterswastika- shaped form.

Title: Excessive current protection circuit and semiconductor device
Inventor: MARUO MASAYA
IPC: H01L29/812
Filed: 1990-09-11
Abstract: PURPOSE:To regulate shut-off characteristics in quick-acting from or delay form according to the load, and eliminate the need for a separate power source by forming an excessive current protection circuit for shutting off eddy current by allowing an N-type junction field-effect-transistor and a P-type junction field-effect-transistor to reciprocally operate. CONSTITUTION:This device is an excessive current protection circuit where a drain of an N-type FET 111 is a terminal A and a drain of an N-type FET 115 is a terminal B. According to this connection, when plus and minus voltages are applied to the terminals A and B, respectively, potential difference in a P-type FET 113 becomes a gate voltage of N-type FETs 111 and 112 and that in an N-type FET 112 becomes a gate voltage of the P-type FET 113. When a voltage VAB is applied between the terminals A and B and the terminal A is plus and the terminal B is minus, a current IAB flowing the N-type FTs 111, 112, 114, and 115 and the p-type FET 113 is increased gradually as the voltage VAB is increased gradually. When the gate voltage of the N-type FET 112 and the P-type FET approaches a certain value, the N-type FET 112 and the P-type FET 113 prevent the current IAB from being increased.

Then the display signal is sent to the CRT 4. Thus the input area of the form is shown in a thick form line. Furthermore the output signal of the circuit 6 is sent and stored into a form memory circuit 8. Hereafter the forms are successively inputted through the keyboard 5, and the input form line of the CRT picture is turned into a thick line. Meanwhile data are stored in the circuit 8. In such a constitution, the handling of a form input device is facilitated together with reduction of input operating mistakes.
