摘要： A semiconductor laser comprises an active layer of a quantum well structure, and a current confinement structure for avoiding the injection of carriers into regions of the active layer in the vicinities of resonator facets. The current confinement structure is different in conduction type from that of one of cladding layer, and is formed by a semiconductor layer which is transparent for a laser light. The semiconductor laser further comprises an optical waveguide structure provided between the resonator facets. In this semiconductor laser, the catastrophic damage is avoided, and the high output power is obtained.

摘要： A connector is adapted to be mounted on a board member. An insulative holder is formed with a through hole connecting a first side face and a second side face which is adapted to be opposed to the board member. The insulative holder accommodates a coiled spring in the through hole such that a first portion of the coiled spring is retractably projected from the first side face. A conductive plate member is attached to the holder. A first part of the plate member is disposed on the second side face of the holder such that a second portion of the coiled spring which is disposed within the through hole is brought into contact therewith. A second part of the plate member is disposed on the second side face separately from the first part, and adapted to receive solder for electrically connecting the coiled spring to a connection electrode provided on the board member. A third part of the plate member connects the first part and the second part while being extended on at least one side face which is other than the second side face.

摘要： A block type dielectric filter including a dielectric block and a plurality of through holes wherein a resonance frequency at individual resonating portions can be set at a specific value even when the dielectric filter is miniaturized. The resonance frequencies can be varied at the individual resonating portions simply by creating a slight change in a coupling factor. The plurality of through holes are provided extending from one surface of the dielectric block toward an opposite surface. Surfaces, except for an open end surface, of said dielectric block are clad with a conductive material layer and a groove is provided on the open end surface between a set of adjacent through holes. The groove is provided offset toward a through hole by an offset quantity.

摘要： A sheet feeding apparatus for image producing systems such a stencil duplicating machine, a printer, and a copying machine. The sheet feeding apparatus comprises a sheet feed roller, a sheet feeding pressure regulator, a pair of register rollers, a sheet feeding time detector, and a control unit. The control unit compares a sheet feeding time detected by the sheet feeding time detector with a predetermined reference sheet feeding time, and controls a sheet feeding pressure on the basis of a compared result during a sheet feeding operation.

摘要： Disclosed is a novel optical system for illuminating an object which provides an increased irradiance in the peripheral area of the object. The optical system includes a light source, an entrance pupil for receiving light from the light source, an exit pupil for passing the light received to the object, and an optical axis which extends through the optical system to the light source and the object, respectively, wherein the relationship among the incident height h to the entrance pupil, an illumination height H on the object, and a changing rate (dh/dH) of the incident height and the illumination height is defined by a function, f(H)=(h/H)(dh/dH). The optical system is designed so as to satisfy the following formula in the peripheral area of the object: f(0)
