The electric power breaker for breaking the electric power is placed on the midpoint of the electric power line from the battery power supply, and the electric power line is extracted from the electric power breaker. In addition, the electric power supply terminal is placed on the midpoint on the electric power line, from which the electric power is supplied to the individual electric loads. The electric power distribution and the electric power supply operation to the electric loads are controlled by the multiplex communication. A semiconductor device having a self protection function is used as the switching device for supplying the electric power. The electric power line covered by the electric conductive material is arranged in a loop topology so as to start from the connection point to the battery and pass through the designated positions in the vehicle and return to the battery. On the designated points on this loop, plural control modules are connected, and the electric power is supplied to them from the battery. By isolating plural electric conductive parts of the electric conductive layer covering the electric power line, each part connected to the abnormality detection circuit of the individual control module, and by detecting the electric potential change in the individual electric conductive part, the position of the abnormality can be identified by the position of the isolated electric conductive part where the short circuit abnormality is detected.

In a print hammer assembly for a dot line printer, print pins are attached to the tip ends of print hammers alternately displaced toward left and right by a predetermined distance from a vertical center of the print hammer, wherein comb portions of a front yoke at both sides of the plunger are made to be an equal width. With such an arrangement, the print pins are not deformed horizontally due to imbalanced magnetic force applied to the associated print hammer at the time of magnetization of a permanent magnet.

A mushroom-shaped gate electrode has a lower end in a recess in a semiconductor active layer on a semiconductor substrate. The gate electrode has an enlarged head. A metallic side wall is disposed on a portion of the leg of the gate electrode adjacent the head. Thus, the gate length of a semiconductor device, such as a field effect transistor, is reduced while the effective cross-sectional area of the gate electrode is increased whereby the noise characteristics of the semiconductor device are improved.

At least two unit transistor groups, each including unit transistors arranged along a straight line, are disposed on a substrate parallel to and facing each other. Each transistor in one group and a facing transistor in the other group have integral first, second, and control electrodes. The first, second, and control electrodes of the unit transistors are connected to associated respective electrode pads.

An apparatus for cutting opposed irregularly shaped ends of veneers to produce opposed inclined end faces and for bonding the veneers together at the inclined end faces thereof, has a cutter which cuts an irregularly shaped end of a veneer to produce an end face inclining from an upper edge to a lower edge a little ahead of the upper edge. The apparatus also has an adhesive-material supplying device with outlets from which an adhesive material is projected. The outlets are located substantially directly above, and in immediate proximity to, an inclined front end face of a following veneer on a first support member. When a second support member is pivoted to bring an inclined rear end face of a preceding veneer thereon into contact with the inclined front end face of the following veneer, the inclined rear end face of the preceding veneer picks off the adhesive material projected from the outlets of the adhesive-material supplying device immediately before coming into contact with the inclined front end face of the following veneer.

A method of producing a semiconductor device includes etching a recessed aperture in a substrate, forming a gate electrode in the aperture, burying the gate electrode with resist, etching the resist to expose the gate electrode, depositing a high conductivity metal on the gate electrode, and forming ohmic electrodes on opposite sides of the gate electrode by a series of processing steps.

A method position measurement in which position about satellite orbits and information about time are received from satellites to determine a position of a point. The method includes a step to calculate a direction in which an error occurs based on positional information of a satellite and a step to determine the position of the point by use of road map information in the direction of the error.

A method of controlling an internal combustion engine employs a microcomputer to control the fuel supply to the engine as well as the ignition timing thereof on the basis of measurement of the air quantity fed to the engine. For measuring the air quantity charged to the engine with high accuracy, the intake air flow fed to the engine is sampled in synchronism with the pulsating variation thereof. A value obtained by averaging the sampled values is used as the intake air quantity on the basis of which the fuel supply and the ignition timing are arithmetically determined.

A terminal block includes a metal plate (30) with an opening (31) penetrating in a plate thickness direction of the plate material and to be attached and fixed to the motor case. A housing (50) made of synthetic resin is fixed to the metal plate (30). Conductive plates (10) are held in the housing (50) while penetrating through the opening (30). The housing (50) includes a flange (52) that covers an edge of the opening (31) while exposing an outer peripheral edge portion of the metal plate (30). The flange (52) includes a wire-side flange (52A) slidable relative to the upper surface of the metal plate (30), a device-side flange (52B) slidable relative to the lower surface of the metal plate (30) and a coupling (52C) arranged in the opening (31) and coupling the both flanges (52A, 52B).

The laser light emitting device includes a glass rod having an input end and an output end. The glass rod has a core provided along the central axis thereof and a cladding covering the core. The refractive index of the core on the side of the input end is higher than the refractive index of the cladding. A value given through subtraction of the refractive index of the cladding from the refractive index of the core on the side of the output end is smaller than a value given through subtraction of the refractive index of the cladding from the refractive index of the core on the side of the input end.
