A pressure sensor comprising a plurality of sensor parts arranged in matrix. A first electrode being connected with first wiring and a second electrode being connected with second wiring are disposed oppositely through a cavity part in the sensor part. The second electrode bends to the first electrode side in response to a pressure from a specimen and touches the first electrode upon application of a pressure of a specified level or above. When the specimen is pressed against a pressure detecting region, both electrodes touch each other at a sensor part corresponding to a protrusion of the specimen and are separated at a sensor part corresponding to a recess. When a scanning signal is fed from a scanning circuit to one wiring and presence of a signal flowing through the second wiring is detected by a sensing circuit, a pressure being applied to each sensor part can be detected. Furthermore, the shape is detected by feeding the scanning signal from the scanning circuit to each first wiring sequentially and scanning the pressure detecting region generally.

A convertible vehicle having a long roof is provided which includes first through third roofs, supported by the vehicle body, movable between a use position at which the roofs cover the upper part of a vehicle interior R and a non-use position at which the roofs are held in a housing unit 21 to the rear of a body 1 so that the upper part of the vehicle interior R is open. A rear door 9 is supported by the body 1 so as to rotatably open and close between a closed position and an open position further to the rear of the closed position, wherein when the first through third roofs 6, 7 and 8 are in a non-use position, the roofs 6, 7 and 8 are accommodated in the housing unit 21, piled up one top of the other in the vertical direction.

An optical communication equipment includes a semiconductor laser element, an image-forming element, an optical fiber and a substrate for mounting the semiconductor laser element, the image-forming element and the optical fiber. An optical output of the semiconductor laser element is adapted to be provided to the optical fiber via the image-forming element. The image-forming element is mounted in a V-groove formed in the substrate and having a substantially “V”-shaped cross-section. A shortest distance between a light spot of the semiconductor laser element and an optical axis of the image-forming element is 1 mm at most and the image-forming element substantially satisfies the sine condition.

A thin film circuit substrate is manufactured by forming a lower thin film electrode on a substrate, forming an organic insulating film with via holes on the lower thin film electrode, and irradiating the substrate with an inert gas ion to remove an oxidized surface film on the lower thin film electrode, and to generate functional groups, such that a modified surface layer with a surface modification coefficient of about 0.1 to about 0.5 is formed on the surface of the organic insulating film, and such that the oxidized surface film on the lower thin film electrode is removed at the same time. Accordingly, a thin film circuit substrate having excellent adhesion strength between the organic insulating film and the upper thin film electrode as well as excellent reliability of electroconductivity between the upper and the lower thin film electrodes is efficiently manufactured.
摘要:
An optical module for an optical device and an optical fiber is constituted by a pre-molded plastic package. In forming the plastic package, the main flowing direction of the molding resin is substantially parallel with the optical axis of the optical fiber. The optical module is formed by molding the resin by an injection method using pressure and then solidifying the resin. When the plastic package is formed by comprehensive molding, the flowing direction of the resin is parallel with the optical axis direction of the optical fiber to be installed in the optical module. As a result, for comprehensive molding, the molding pressure applied to the optical fiber is reduced. By using the resin case that is formed, the resulting package exhibits high rigidity and low thermal expansion properties in connection with the flowing direction of the resin, thus reducing the external stress and thermal stress applied to the optical fiber.
