According to one embodiment, there is provided a protection relay. The protection relay includes an input circuit that detects a state of an external device according to whether or not an external input voltage is larger than a preset threshold voltage. The input circuit includes switching unit that is made conductive by a divided voltage obtained by voltage-dividing resistors that divide the external input voltage when the external input voltage is higher than or equal to the threshold voltage, and a photocoupler that is operated by a constant current of a constant current output circuit supplying a constant current and outputs an operation signal to the operation unit when the switching unit is made conductive.

An optical touch panel comprises a transparent plate, a plurality of light-emitting devices and a plurality of light-receiving devices arranged around the transparent plate, a first substrate to which some of the light-receiving devices are fixed, and a second substrate to which others of the light-receiving devices are fixed. Each of the substrates has a surface layer that has a surface roughness which causes diffuse reflection of the same kind of light as light emitted by the light-emitting devices. A region having the surface roughness on a surface of the surface layer includes a region on the surface of the surface layer included in directivity ranges of the light-receiving devices fixed to the substrate.

A plurality of optical fibers are bundled, and the fiber bundle is cut at a part of a mouthpiece which is fixed on an intermediate part of the fiber bundle. Thus, the fiber bundle is divided into a first optical fiber bundle and a second optical fiber bundle. Division surfaces of the first and second optical fiber bundles have the same properties and condition since the first and second optical fiber bundles are formed of the fiber bundle that is obtained by bundling the same optical fibers. The first optical fiber bundle is assembled in an insertion section of an endoscope and the second optical fiber bundle is assembled in a flexible tube, and a first light guide in the insertion section of the endoscope and a second light guide in the flexible tube are formed. Thereby, a separable light transmission path of the light guide is formed.

A semiconductor laser device includes: an electrically insulating film on the top face of a laser chip; and a metal film, on the electrically insulating film. The electrically insulating film and/or the metal film has, in plan, a polygonal shape with five or more apexes, each of the apexes having an interior angle less than 180 degrees. Stress due to a change of temperature during operation is reduced, resulting in a semiconductor laser device having a longer life and higher reliability.

A ridge waveguide semiconductor laser includes an active layer, semiconductor layers on the active layer and having a ridge-shaped waveguide, an insulating film on the semiconductor layer, a first electrode layer in contact with the semiconductor layer through an opening in the insulating film, and a second electrode layer on the first electrode layer having a stripe shape and extending along the waveguide. A distance from an end face of a resonator of the laser to an edge of the second electrode layer does not exceed 20 &#x3bc;m.

An electrode for a semiconductor device includes a gold-containing thin film and a gold-containing plated film on the thin film. The plated film covers the entire thin film. No open surface is present between the thin gold film and the gold plating so no excessive current concentration occurs in any area.

A simplified screen printing machine includes a base member having a print base with an elastic member for mounting an object to be pressed; a framed stencil sheet assembly including a stencil sheet formed of a porous support and a resin film laminated to the support and a frame member laminated with the stencil sheet; and a pressing device attachably and detachably assembled with the framed stencil sheet assembly for pressing the framed stencil sheet assembly to the base member. The pressing device has an opening for receiving at least a part of the print base therein. When the pressing device with the stencil sheet assembly is disposed on the print base with the object, the print base is at least partly located in the opening to thereby stretch the framed stencil sheet assembly with tension.

According to a field ground fault detector, a predetermined resistor is connected in series to a predetermined DC voltage. A DC voltage is applied between an N electrode side field circuit of a generator and a ground through the resistor. A voltage applied between terminals of the resistor is input to a low-pass filter. A voltage applied between the N electrode side field circuit and the ground is input to another low-pass filter. Output voltages of the low-pass filters are input to a level ratio determining circuit. The level ratio determining circuit outputs the determined result of the ground fault to the outside of the field ground fault detector corresponding to these voltages. Thus, even if the DC voltage varies or a higher harmonic voltage takes place in a generator of a thyristor exciting type, it does not affect the detecting sensitivity of the ground fault.
