Title: Conductive cantilever structure of compound microscope
Inventor: KAWAMI HIROSHI
IPC: G01N37/00
Filed: 1994-08-09
Abstract: PURPOSE:To precisely detect change in capacitance between a probe and a sample by forming an insulating film on the rear surface or the whole face of a cantilever and covering its upper part with a metal sheath which is grounded. CONSTITUTION:The rear end part of a cantilever 1 made of a rectangular metal plate is fixed and bonded to a holder 2. A shape probe 3 is formed at the front end of the cantilever 1. The rear surface of the cantilever 1 is covered with an insulating film 4. The lower part of the insulating film 4 is covered with a sheath 5 mode of a metal. SiO2, Si3N4, Si or the like is used for the insulating film, and gold, copper, aluminum, silver or the like is used for the metal. A conical insulating film 6 and a conical metal film 7 are formed into a concentric shape around the probe 3, and the tip of the probe 3 protrudes slightly so as to be situated in a position close to a sample 8. The sheath 5 is grounded. Since the insulating film 4, which is thin, is situated between the sheath 5 ad the cantilever 1, a capacitor is formed. In addition, the cantilever 1 is shielded by the sheath 5, a capacitance between it and the sample 8 is extremely small.

Title: Probe card
Inventor: IZAWA RIYUUICHI
IPC: G01R1/073
Filed: 1982-12-01
Abstract: PURPOSE:To make leak currents and parasitic capacity small, by using shielded wire as wiring for a probe card. CONSTITUTION:In a probe card, which is used in a semiconductor measuring device for wafer inspection and the like, a probe 1 is connected to a wiring 42 through a wiring 41, which pierces through an insulated substrate 43. Shielded wire, coaxial cable, double shielded cable, and the like are used as the wiring 42. The wiring 42 is provided in a jump wiring manner to a probe card connector connecting part. The substrate 43 is formed by a transparent insulating material so that the entire surface of the wafer can be seen. Since the length of the wiring of the probe card contacting with the insulating substrate 43 becomes the width W of the insulating substrate 43, the leak currents and parasitic capacity become small. When the substrate 43 is made hollow, the length of the substrate is made short, and the leak currents and the like can be made further small.

IPC: B62D1/04
Filed: 1994-09-02
Abstract: PURPOSE: To reduce the generation of an unusual sound when a reversal part is moved in the circumferential direction by providing a projection extending in the circumferential direction in the upper inner surface of a housing opposite to the side edge of the reversal part of a flat cable. CONSTITUTION: When a rotary body 1 fixed to a steering wheel is rotated with respect to housings 5, 7 fixed to a steering column, a flexible flat cable (FFC) for making the electrical connection between both members moves a reversal part 11a in the circumferential direction between the outer circumferential surface of the rotary body 1 and the inner circumferential surface of the housings 5, 7 so as to deal with it. At that time, even when the FFC 11 is moved to the upper inner surface of the housing 5 opposite to the axial direction of the rotary body 1, it is brought into contact with the projection 49 to slide in the state of a small contact area. Also, the central part of the reversal part 11a is not brought into contact with the housing 5. Therefore, the generation of an unusual sound can be suppressed or avoided.

Title: Low-pressure mercury vapor discharge lamp
Inventor: YORIFUJI TAKASHI
IPC: H01J61/28
Filed: 1986-09-09
Abstract: PURPOSE:To allow the title lamp to be used in a wide temperature range by containing mercury and a substrate metal composed of a specific quantity of bismuth, indium, and silver in an amalgam. CONSTITUTION:Mercury 1-10wt.% of the whole amalgam and a substrate metal composed of bismuth 50-80wt.%, indium 10-49.5wt.%, and silver 0.5-10wt.% are contained in the amalgam sealed in a bulb. Therefore, the mercury vapor pressure can be controlled adequately in a wide temperature range. Since the substrate metal is produced in a single phase eutectically, no component metal is separated and crystallized while a lamp is in use, and it can be operated stably. In addition, the content of mercury is determined, thus there is no shortage of mercury while in use for a long time. Accordingly, this lamp withstands a high temperature, and excellent luminous efficiency can be obtained in a wide temperature range of 80-150 deg.C.
