A solar cell array used in a photovoltaic power generation apparatus for housing covers a relatively large outside area for installation, and a considerably large earth capacitance Ca exists between the solar cell array and the ground. Further, as an inverter for converting direct-current electric power generated by the solar cell array into alternating-current electric power, a transless-type inverter is used for reducing cost. Therefore, a slight leak current flows via the earth capacitance Ca, which may cause undesirable operation of an earth leakage circuit breaker inserted between the inverter and a commercial AC power system. In the photovoltaic power generation apparatus of the present invention, by designing it so that the relationship between the earth capacitance Ca[.mu.F] and leak current detection sensitivity EL[mA] of the earth leakage circuit breaker is Ca

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.
