Title: Semiconductor laser
Inventor: KAWANO HIDEO
IPC: H01S5/00
Filed: 1990-12-03
Abstract: PURPOSE:To perform a lateral mode control with high reliability by disposing an optical guide layer having a stripelike mesa shape, adjacent to an active layer, and forming refractive index distribution by thickness change of the guide layer. CONSTITUTION:A made effective refractive index difference of a parallel direction is formed at an active layer 14 by thickness change of an optical guide layer 15 at a mesa and both sides thereof to obtain a refractive index distribution of a real number component without absorption loss. Accordingly, a basic lateral mode oscillation is generated with a low astigmatism at a low oscillation threshold value. The thicknesses of the layers 15 at both sides of the mesa can be designed thickly to 0.3-0.4mum, and thermal damage of the layer 14 when a current blocking layer 18 is grown by second MOVP growth is alleviated. Thus, a semiconductor laser with high reliability can be formed.

Title: Method for drawing out lead wire from motor
Inventor: SAKAI KAZUMA
IPC: H02K3/50
Filed: 1990-12-04
Abstract: PURPOSE:To reduce the restoring forces of a plurality of lead wires against the strength in the bottom section at a coil end, namely, against bends by departing at least one of the bundled lead wires led out from one side toward the bottom section of the coil end from the other lead wires by loosening the lead wire. CONSTITUTION:At the time of forming a drawing-out section 21, namely, at the time of bending lead wires, the central one of the three wires is loosened by giving a margin in length to the wire and the other two wires are bent at nearly right angles against a stator core 2. It is preferable to fix the vicinity of the bent section of the section 21 with a tying string 22. When the lead wires are fixed in such way, the lead wires can be easily bent and set perpendicularly to the stator core 2, since the bent sections of the three lead wires 7A, 7B, and 7C are separated from each other and, especially, the central one is largely separated from the other two. In addition, since the central lead wire has a margin in length, the drawing-out section 21 is hardly moved even when the lead wires are pulled toward a cluster at the time of connecting the lead wires to the cluster.

Abstract: PURPOSE:To correctly measure the size without being affected by the fluctuation of the reflectance by dividing the reflected light into two, detecting the whole reflected light intensity from one reflected light, and detecting the reflectance of a size section from the other reflected light. CONSTITUTION:The reflected light from a measured object 12 is reflected by beam splitters 105, 115 and divided into two. The first light reception section 13 detects the whole intensity light of the reflected light portion 140 to generate the reflected light intensity pattern indicating the relation between the deflection position on the face of the measured object 12 and the reflected light intensity for each period of deflection (scanning). The second light reception section 14 detects the reference light intensity which is the intensity of part of the reflected light region containing the peak intensity light portion of the reflected light portion 145, generates 16 the reference light intensity pattern indicating the relation between the deflection position and reference intensity in one period of deflection, and determines the reflectance of a size section against the base section of the measured object 2. The correlation range between the size and reflected light intensity using the reflectance as a parameter is determined from the reflected light intensity pattern, and the size is calculated 17 by referring to both data.

The method comprises the steps of selecting within the medium one or a plurality of ends of rectilinear measuring runs, which ends are embodied by an inner artificial reflector (8, 9) emitting of a beam of acoustic waves so that acoustic rays carrying sufficient energy strike the useful reflectors, selecting the echoes corresponding to the reflectors, determining by measurement the transit times which are characteristic of the useful acoustic rays up to the inner artificial reflectors and transposing the transit times for each inner reflector considered individually or the respective differences of transit times for each couple of reflectors into an outer strain value or into a strain value within the region delimited by each couple of reflectors. The part for implementing such method comprises reflectors consisting particularly of perforations or bores into the part.

Abstract: The valve assembly has inlet and outlet members with valve elements disposed between the two members. The valve is a resilient membrane having one or more through holes. When there is no pressure differential across the valve, the hole walls in the membrane collapse inwards closing off the valve against liquid flow. At or above a threshold pressure differential across the valve, the membrane is stretched which opens up the hole or holes to allow the passage of liquid.
