A rear gate opening and closing apparatus includes a gas stay for biasing a rear gate in an opening direction, a motor for actuating to open or close the rear gate, a clutch for connecting or disconnecting the motor with the rear gate, an encoder for detecting the position of the rear gate, an operating switch for operating an opening and closing motion of the rear gate, and a control means for controlling the motor and clutch to automatically open and close the rear gate. The opening and closing speed of the rear gate is controlled based on a detection signal of the encoder.

An optical communication unit includes a light emitting element for emitting a transmission signal light; a condenser lens for coupling the transmission signal light from the light emitting element to an optical transmission path; and a light receiving element for receiving a receiving signal light from the optical transmission path. A light emitting surface in the light emitting element is formed by a plane tilted to a perpendicular plane in a substrate surface of a chip in the light emitting element.

A tube is inserted into a first liquid layer, and an air bubble is generated at a tip opening of the tube. The tube is then moved toward a second liquid layer while retaining the air bubble, and a change in the internal pressure of the tube caused by the air bubble reaching the boundary between the first and second liquid layers is detected. After the tip opening of the tube is raised to the top surface of the first liquid layer, the first liquid is sucked up by the tube while the tube is moved to the position where the pressure change was detected.

A transceiver module for optical communication includes a light-emitting element, a light-receiving element and a rod lens. Light from the light-emitting element is condensed onto the top end of the rod lens. A ferrule of an optical fiber is brought into physical contact with the top end surface of the rod lens so as to couple the light-emitting element and the light-receiving element with the optical fiber. The rod lens is held by a support supported by a spring member on a housing, and the outer diameter of the rod lens is formed so as to be substantially equal to the outer diameter of the ferrule. An opening portion is provided in the housing so that the top end of the ferrule of the optical fiber is slidably fitted into one end of a sleeve, the other end of which is slidably fitted onto the outer circumference of the rod lens. Also, a transceiver module includes a light-emitting element for emitting transmission signal light, a coupling lens for connecting the transmission signal light emitted from the light-emitting element to a light transmission path, and a light-receiving element for receiving detection signal light from the light transmission path, in which the transmission signal light emitted from the light-emitting element is reflected on a surface of the light-receiving element and connected to the light transmission path through the coupling lens; and the detection signal light from the light transmission path is received by the light-receiving element.

A semiconductor device that has a feature in the spatial relationship between the wiring in a multi-level wiring and the intermediate insulating films. In the lower part of the second and/or subsequent levels of wiring there exist intermediate insulating films that have a pattern which is the same as the pattern of the wiring. Because of this arrangement, the intermediate insulating film does not exist between the wiring on the same level. The first structure of the multi-level wiring has the intermediate insulating films formed in wall-like shape, with the lower end of the intermediate insulating films reaching an underlying insulating layer formed on the surface of the semiconductor substrate. The second structure of the multi-level wiring is a quasi air gap metallization structure. As a result of realization of such structures, in the semiconductor device according to the present invention, the parasitic capacitance due to the coupling capacitances between the wiring can be reduced compared with a semiconductor device that has a structure in which the spaces between the wiring are filled with the intermediate films.
