An electrical connecting member is provided with a holding member made of an electric insulating material and a plurality of conductive members held by the holding member in a state of being insulated with each other. One end of each of the conductive members is exposed on one surface of the holding member and the other end of each of the conductive members is exposed on the other surface of the holding member. The conductive members have portions exposed from the holding member, the length of which is longer than the thickness of the holding member. These exposed portions are easily deformed by the pressure force exerted at the time of connecting electric circuit components to reduce the coupling load even when there is irregularity in the heights thereof or unevenness in the junctions of the objects connection, hence enabling high density connections between the electric circuit components. The exposed portions can also be formed to have empty holes 1B, to be porous or, in the alternative, annealed to soften the exposed portions.

An automobile mirror assembly improves safety during driving of a car by widening the visual field of the driver with little distortion. The mirror is mounted on a car with a support member and a holding member to be adjustable in its position. A gradually changing mirror section is provided on at least one of an upper, lower and side edges of a main mirror section of the mirror. A surface of a gradually changing mirror section is defined by a plurality of intersections between curved surfaces provided in at least one of a vertical and horizontal directions with hyperbolic curves provided in a direction perpendicular to one of the vertical and horizontal directions. Each respective curved surface passes through circular arcs, the radii of curvatures of the circular area being calculated from Equation 1 indicated below. The radii of curvatures of the circular arcs gradually become smaller in an extending direction. The intersection of the hyperbolic curves and the curved surfaces define the surface of the gradually changing mirror. The Equation 1 is as follows: ##EQU1## where: A1, A2, . . . An-1, An are asphericity factors representing asphericity at respective portions in the at least one of the horizontal and the vertical directions, n is any integer, K=0, and C=1/r0, and wherein r0 represents a radius of curvature at a starting position of the gradually changing mirror section.

The jigsaw puzzle according to the present invention comprises a substrate and transparent member. The substrate has a painting, photograph or pattern provided on at least the first side thereof and is cut into a multiple of irregular, interlocking pieces. The transparent member has marked thereon a figure which is to conceal at least a part of the cut lines in the substrate, and is to be disposed on the first side of the substrate. Since the zigzag cut lines in the substrate are concealed by the figure marked on the transparent member, the jigsaw puzzle having the picture thus reproduced can be an improved interior decoration.

A fuel injection control system having an intelligent timer (TPU) to perform fuel injection control using the TPU even on request of asynchronous injection which is not synchronous with rotational angle signals. A central processing unit (CPU) calculates a value to be used during the execution of a synchronous injection (e.g., a fuel injection time) and an asynchronous injection time and stores these values in a parameter RAM. The CPU determines whether there is a request for an asynchronous injection from, for example, the quantity of a change in the opening of a throttle. The TPU also executes a synchronous injection if there is no asynchronous injection request. If there is an asynchronous injection request, it transmits an on output from input/output pins and causes a compare register to store a value which is the sum of the current time and an asynchronous injection time. It transmits an off output from the input/output pins if this value agrees with a value in a first free run counter.

A displacement information detection apparatus for detecting relative displacement information regarding the apparatus and an object to be detected includes an illumination system for radiating coherent light. A first diffraction grating splits the coherent light from the illumination system into first and second light beams, which are radiated onto the object. A second diffraction grating synthesizes the first and second light beams emerging from the object to generate an interference light beam. A light-receiving element detects the interference light beam and detects the relative displacement information regarding the object and the apparatus upon reception of the interference light beam. The illumination system is configured to focus the first and second light beams at a location along an optical path between the first diffraction grating and the second diffraction grating, so that the interference light beam incident on the light-receiving element is a divergent light beam.

A system for cleaning and film-forming a semiconductor wafer continuously comprises a washing section for removing native oxide from the surface of the wafer while applying hydrofluoric acid to the silicon wafer, a load lock chamber located adjacent to the washing section and filled with the atmosphere of non-oxidizing gas, a film-forming section communicated with and shielded from the load lock chamber by a gate valve to form film on that face of the wafer which is to be processed, a first transfer robot for transferring the wafer between the washing section and the load lock chamber, and a second transfer robot for transferring the wafer between the load lock chamber and the film-forming section. Film is formed on the wafer in the film-forming section after the native oxide is removed from the wafer.

The present invention provides an automobile antenna system for detecting high-frequency surface currents induced on the vehicle body by external broadcast waves and supplying the detected signals to various built-in receivers. The automobile antenna system includes a high-frequency pick-up device positioned on the vehicle body at a pillar along the length thereof at which there is less noise and the density of the broadcast waves is increased.

A keyless entry apparatus for locking and unlocking a door, trunk lid, and window of a vehicle uses electric waves radiated from a transmitter which are received by a pickup which is provided on a vehicle body in a concealed state without any external exposure which would impair the aesthetic appearance of the vehicle body. The pickup consists of a loop antenna or an electrostatic detection antenna which detects the surface currents induced on the vehicle body by the electric waves radiated from the transmitter. The pickup is disposed at a portion on which the surface currents are concentrated such as, for example, a front pillar, trunk lid and roof.

A method for assembling narrow gap members by welding is described. In the method, separate narrow gap members having spaces therein when assembled are provided and a deformation-preventive material consisting of a water-soluble material or a material capable of being disintegrated with water is filled in each space and is formed with a through groove or hole in the filled preventive material. In this state, the separate narrow gap members are subjected to welding, and immersed in water to remove the deformation-preventive material from each space. The through grooves may have a width larger than a leg length of each penetration bead, in which a heat-resistant flux is filled in each groove. The deformation-preventive material may be covered with a heat-resistant ceramic backing member shaped in a specific form or with a heat-resistant particle layer and a copper member shaped in conformity with an intended size and shape of a penetration bead.

An automobile antenna system for detecting currents induced in a vehicle body by broadcast waves and transmitting the detected current signals to a receiver located in the vehicle body is provided without externally projected antenna poles. The system comprises high-frequency pickup means longitudinally disposed along and in close proximity with the marginal edge portion of the vehicle body, the pickup means being effective to detect surface high-frequency currents which are induced on the vehicle body and concentrated into the marginal edge of the vehicle body, for example, a vehicle roof panel, a rearwindow frame or a vehicle fender. The pickup means is spaced away from the marginal edge of the vehicle body within a range represented by the following formula: 12.times.10.sup.-3 c/f(m) where c=the velocity of light and f=the carrier frequency of broadcast waves.
