Title: Burried semiconductor laser element
Inventor: HOSODA MASAHIRO
IPC: H01S5/00
Filed: 1987-01-23
Abstract: PURPOSE:To make multilayer crystals fully thick without causing its layer to grow on a mesa part and suppress the development of a leakage current by restricting the thickness of two layers consisting of a clad layer that is laminated on an active layer in a BH-VSIS type semiconductor laser element as well as a protecting layer that is laminated on the clad layer. CONSTITUTION:A P-GaAlAs clad layer 3, a flat non-doped GaAlAs active layer 4, an N-GaAlAs clad layer 5, and an N-GaAs protecting layer 6 which fill up a V-shaped groove 12 with an LPE technique are laminated in sequence and doublehetero junction structure multilayer crystals are formed. The N- GaAlAs clad layer 5 grows to have a layer thickness of 1.8mum, while the N- GaAs protecting layer 6 grows to have the layer thickness of 0.8mum. The layer thickness of the P-clad layer 3 and the protective layer 4 shall be within a range of 0.1-1mum at flat parts. The multilayer crystals corresponding to both sides of the V-shaped groove part 12 are removed by etching and a stripe-shaped mesa part 13 is formed. As a leakage current Il does not develop and all of implanted carriers contribute to emitting a light, a threshold electric current as a semiconductor laser element shows a drastic decrease.

Title: Inspecting method and machining method for v-shaped groove
Inventor: ISHIDA HIDETOSHI
IPC: G02B6/36
Filed: 1992-01-30
Abstract: PURPOSE:To inspect a V-shaped groove more highly accurately by using a contact-type shape measuring apparatus or an optical contact type measuring apparatus, and measuring the positions along the inner surface of the V-shaped groove. CONSTITUTION:For example, V-shaped grooves used in an SV optical connector are formed as follows. V-shaped grooves 12 for positioning optical fibers and V-shaped grooves 13 for positioning guide pins are formed an the surface of a silicon substrate 11 by grinding using V-shaped grindstones.

Filed: 1990-01-26
Abstract: PURPOSE:To attain high reliability and improve machining efficiency by measuring the relative position between two or more tools and works, correcting the relative position between the works for machining so that the machining allowance is made nearly uniform at the subject position in the numerically controlled machining method. CONSTITUTION:In the numerically controlled machining method, the pre-machining face prior to machining is measured, the control program of a machine tool is corrected by the error between the original point of a work distributed with the machining allowance so that the machining allowance at the time of machining is made nearly uniform at the machining subject position and the machining original point of the machine tool or the parallel shift drift of the rotating angle drift of the coordinate system of the work against the coordinate system of the machine tool, and the work is machined based on the control data. If the left end position of the work prior to machining is measured as x1 and the right end position is measured as x2, for example, the machining allowance DELTA=(x1+x2-L)/2 is removed at one end by machining, and the machining allowance DELTA=(x1+x2-L)/2 is removed my machining at the other end.

Title: Temperature detecting sensor
Inventor: OTSUBO TAKATOSHI
IPC: G01K11/00
Filed: 1991-02-06
Abstract: PURPOSE:To detect temperature with a simple constitution wherein the coil of shape memory alloy is deformed with the heat generated in a conductor when the temperature of the coil exceeds a preset temperature, the end part of the coil comes into contact with the inner surface of a container, and sound is generated. CONSTITUTION:A sound generating part 3 is attached to a conductor 6 in a closed switchboard 1. When an overcurrent flows, the temperature of a coil 8 made of shape memory alloy which is attached to a bolt 4 rises owing to the heat generated in the conductor 6. When the temperature exceeds a deformation temperature (t), thermal deformation occurs instantly. The wire forming the coil tends to deform in the straight line. Since the coil 8 is contained in a cylindrical metal fitting 9, however, the wire cannot be deformed in the perfect straight line, and the winding state is loosened in a short time. At this time, a needle-shaped part 8a of the end part of the coil 8 comes into contact with tooth-shaped projections 9a and quickly turns in the inside of the metal fitting 9. Metallic sound is generated by the contact. The sound is picked up with a microphone 2 and measured with a sound measuring device 10.
