Title: Optical semiconductor device and its manufacture
Inventor: SAKATA YASUTAKA
IPC: H01S5/343
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To enlarge a contact area with a p-clad layer and prevent reduction of contact resistance by burying a core layer side surface by a p-type semiconductor layer, and making the carrier concentration at the side in contact with an n-type semiconductor substrate or an n-type semiconductor clad layer thereof higher than the carrier concentration in an opposite side. SOLUTION: A ZnO film 103 is deposited on an n-InP substrate 101 and an optical waveguide structure consisting of an n-InP layer 106, a stained InGaAsP/InGaAs multiple quantum well active layer 107, and a p-InP layer is selectively formed in an opening part. In the process, because of high temperature of a substrate, zinc is subjected to solid phase diffusion from a ZnO film to the n-InP substrate 101 and a p-type inversion region 105 is formed. Then, a current block layer consisting of a p-InP layer 110 and an n-InP layer 111 is subjected to burying selective growth only for a mesa top of a p-InP layer 108. Lastly, a p-InP clad layer 112 and a p-InGaAs cap layer 113 are made to grow and an SiO2 interlayer film, a p-electrode and an n-electrode are formed.

IPC: E02F9/00
Filed: 1982-09-21
Abstract: PURPOSE:To match operating sense with the direction of a vehicle even when a slewing body turns backwards by switching an oil-pressure circuit between a steering valve and a cylinder to vary the direction of the vehicle by using an operating oil path provided to a central coupler connecting the running vehicle with the upper slewing body. CONSTITUTION:When the upper slewing body 2 of a running vehicle, e.g., oil- pressure shovel, etc., slews toward the front of a lower runner 4, the fourth port P4 is led through a communication hole 24, a circular groove 13a, and c communication hole 20 to the sixth port P5, and the third port P3 is led through a communication hole 23, a groove 13b, and a communication hole 19 to the fifth port P5. When a steering handle 5 is turned to the right, pressure oil passes through the ports P1, P3, and P5, a steering cylinder 17 is contracted, and the vehicle 12 is turned to the right. When the slewing body 2 slews backwards, a spindle 9 is turned through 180 deg., the port P3 is led to the port P6, and the port P4 is led to the port P5. When the handle 5 is turned to the right, the steering cylinder 17 is extended and the vehicle retreats to the right.

Title: Manufacture of decorative laminated sheet
Inventor: UEDA YOSHIYUKI
IPC: B29C55/00
Filed: 1978-12-30
Abstract: PURPOSE: To produce a decorative laminated sheet having a sharp embossed figure and a natural shade, by laminating together a thermoplastic film laid on a base material having a concave and convex portions on a surface thereof by heating them to higher than a softening temperature of the film.  
     CONSTITUTION: A film 3 with a thickness of 5W80μ made of a thermoplastic resin is adhered to a base material 2 having a concave and convex portions on a surface, the film and the base material being laminated together by heating them to higher than a softening temperature of the film 3. A woody material such as a plywood having concave and convex portions being based on vessels is used as the base material 2. A decorative effect is obtained resulting from the adoption of a transparent film or resulting from printing of the grain of wood on both surface. In decorative laminated sheet so produced, natural vessels of a plywood used as the base material 2 appear on a surface as a result of the film 3 encroaching upon the concave and convex pattern based on the vessels, irrespective of that on embossing process takes place. This causes the plywood vessels to match the grain of wood printed on the film 3, and thereby an appearance becomes rich in a natural beauty. An adhesive property is also improved due to encroaching of the film 3 upon the concave and convex portions 1.

Title: Solid laser equipment
Inventor: KUBA KAZUKI
IPC: H01S3/0915
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a soled laser equipment of high efficiency which is superior in beam quality and output stability by making the end face of a laser medium a vertical rectangular parallelepiped to an optical smooth surface and arranging a plurality of all the reflecting parts and partial reflecting parts at the end part thereof. CONSTITUTION:A slab 1 in which the whole area is nearly unifomly excited by a lamp 5 and a substage condenser 7 is taken out as a laser beam 11d a by resonator in which part of energy is composed of a partial reflecting mirror 10a, wholly reflecting mirror 10b and return mirrors 9a, 9b and the greater part of the other energy is cleared by indirect cooling from a slab surface 12. At this time a square temperature distribution of high temperature in the center part is generated in the slab, but, since whole the area is nearly uniformly excited and nearly uniformly cooled from the whole surface of the slab, a temperature gradient nearly produces in the thickness direction alone, a refraction factor distribution does not only produce in the width direction because it produces nearly in the thickness direction, but also that refraction factor by the temperature distribution does not produce longitudinally. Therefore, an inexpensive device of high efficiency which is superior in beam quality and output stability can be obtained.

Abstract: PURPOSE:To prevent excessive cutting from being generated, by outputting only a point in a case where a normal vector is larger than the tool radius of a flat end mill as NC data when the normal vector is set in parallel with the direction of the tool central axis of the flat end mill.

Title: Paging receiver
Inventor: SCHEINERT STEFAN DIPL ING
IPC: H04B1/16
Filed: 1988-07-07
Abstract: PURPOSE: To save energy by connecting an evaluation means and a comparison register to one comparator and further connecting the output terminal of the comparator to an electric feeding divider. CONSTITUTION: The evaluation means 14 and comparison register 13 are connected to one comparator 4, whose output terminal is connected to the electric feeding divider 2. Namely, the comparator 4 decides whether or not data which are receivable up to the end of a data block are important to evaluate all data blocks during the reception of the data block so as to immediately compare the receive data with presettable data. Therefore, a data block need not be received to its overall length almost in all cases and a receive subset can be already switched off before the end of the data block arrives. Consequently, energy can be saved.
