Title: Semiconductor laser
Inventor: KAMISATO TAKESHI
IPC: H01S5/00
Filed: 1993-08-17
Abstract: PURPOSE:To reduce reactive current passing through the window structure of a semiconductor laser that is formed by introducing impurities into regions in proximity to the end faces of a laser resonator. CONSTITUTION:An active layer 3 has its quantum well structure disordered in its regions 9 in proximity to the end faces of a resonator. Current leakage paths are so formed as to include impurity introduced regions formed by introducing impurities in proximity to the end faces of the resonator. A substrate 1 and a contact layer 5 are etched off by a specified amount from the resonator end face 15 side in the direction of the length of the resonator so that part of the current leakage paths will be removed. This allows reactive current to be reduced during laser operation, which realizes a low-power-consumption semiconductor laser that needs lower operating current to oscillate laser to obtain a desired optical output.

Abstract: PURPOSE:To decrease the bending curvature of an optical fiber when light is bent at 90 deg. for irradiation by fitting a prism which bends the optical axis at 90 deg. to the tip of the optical fiber whose base end part is connected to a light source. CONSTITUTION:The optical fiber 1 is formed flexibly by bundling many extremely thin optical fibers and ferrules 7 and 8 are fitted to the base part and tip part of the optical fiber 1. Then the prism 2 is joined and fitted to the tip end surface of the optical fiber 1. The prism 2 is sectioned in a right-angled triangular shape and a mirror surface 6 which reflects light passing through the prism 2 is provided on the surface of the oblique side. Namely, the light from the light source 3 is guided into the optical fiber 1 to enters the prism 2 from the tip end surface and then has its optical axis turned at 90 deg. before irradiation. Therefore, when the optical axis is bent, the optical fiber 1 need not be bent and the curvature of the optical fiber can be made small.

IPC: H01L23/28
Filed: 1987-08-18
Abstract: PURPOSE:To eliminate causes of failures, by covering the surface of a wire and a lead in the inside of sealing resin with a film of high reactivity, and eliminating the gap between the sealing resin and the wire or the lead. CONSTITUTION:After the surfaces of a wire 3 and a lead 2 in the inside of sealing resin are covered with material 5 whose reactivity is higher than the wire 3 and the lead 2, sealing is performed. When contamination elements permeate from the outside and reach a chip 1 travelling through the lead and the wire, the contamination elements react, on the way, with the film 5 covering the lead and the wire whose reactivity is higher than the lead and the wire. Therefore, stable compounds are formed, and the deeper permeation can be prevented. Thereby, the failure of semiconductor device can be reduced.

Title: Image rotator device and scanning optical microscope
Inventor: UENODAI ASAO
IPC: G02B21/00
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To remove vignetting due to the pupil of an objective lens and to easily make a device a small unit without irregularity of illumination at the time of rotating an image rotator by arranging the image rotator close to the pupil position of an objective optical system. SOLUTION: An image rotator 50 is arranged in the vicinity of a pupil 52 of an objective lens so that the rotating center is made nearly coincident with the optical axis. Thus, since a distance x between the image rotator 50 and the pupil 52 of time objective lens becomes small, even when a deviated amount 6θ1 is generated between the optical axis and the rotating center of the image rotator 50, the revolving radius (r) of a light spot, is suppressed to be small. This means that the possibility of generation of vignetting due to the pupil 52 of the objective lens by the revolution of spot light is reduced and irregularity of illumination is removed. As for the relation between the image rotator 50 and an image forming lens, since the rotator is arranged near the pupil 52, the size of the image rotator 50 becomes small.

Filed: 1987-08-17
Abstract: PURPOSE:To enable a metallic rear-face electrode to be divided easily and effectively without adversely affecting photovoltaic properties, by performing formation and division of the rear-face electrode before formation of a semiconductor layer. CONSTITUTION:Manufacture of a thin-film solar cell comprises a step of forming a rear-face electrode 2 while leaving a predetermined width of opposite peripheral edges of e light-transmitting insulating substrate 1, a step of dividing the rear-face electrode 2 into rear-face electrode sections 2a-2n corresponding to respective photovoltaic element forming regions, and a step of forming terminal electrodes 3r, 3l by electroless plating such that one of them is in contact with the rear-face electrode section 2n while the other is not in contact with the rear-face electrode section 2a.

Title: Solid-state image sensor
Inventor: TANAKA SHOICHI
IPC: H04N5/335
Filed: 1986-08-29
Abstract: PURPOSE:To improve the blue sensitivity of an image sensor and to control the blooming by a method wherein an N type storage gate region is formed on the surface of a P type channel region located between a source region and a drain region and an N<+> control gate region is buried under a P<+> source region and the P type channel region. CONSTITUTION:Control gate regions 2L-2M of the second conductivity type are formed on the surface of a substrate 1 of the first conductivity type, and on this surface a channel region 3 of the first conductivity type is formed. Then, on this surface a source region 4 of the first conductivity type, a drain region 6 of the first conductivity type and a storage gate region 5 of the second conductivity type are formed. The source region 4 of the first conductivity type which is formed above the control gate regions 2L-2M of the second conductivity type is connected with the drain region 6 of the first conductivity type through the channel region 3 of the first conductivity type which is sandwiched between the storage gate region 5 of the second conductivity type and the control gate regions 2L-2M of the second conductivity type. Therefore, because the potential of the channel region 3 is controlled directly by the potential of the buried control gate regions 2L-2M provided under the channel region, it is possible to break the channel by giving an intermediate potential to the control gate region regardless of the potential of the storage gate region 5.
