Patent JP-H05121828-A (JP)
Title: Semiconductor laser
Inventor: KAWANO HIDEO
IPC: H01S5/00
Filed: 1991-10-18
Abstract: PURPOSE:To provide an A GaInP system visible light semiconductor laser which has a low oscillation threshold and, further, a small astigmatic difference and is oscillated in a basic lateral mode. CONSTITUTION:An active layer 15 is provided between an optical waveguide layer 16 having a stripe-shaped mesa structure and an A0.5In0.5P light reflective layer 14. Current blocking layers 19 which do not absorb an oscillated light are provided on both the sides of the mesa part of the optical waveguide layer 16. With this construction, a built-in effective refractive index difference along a direction in parallel with the active layer is obtained by the variation of the thickness of the optical waveguide layer on the mesa part and both the sides of the mesa part, so that a refractive index guide type laser which has a low oscillation threshold and a low astigmatic difference can be realized. Further, as the oscillated light is spread into the optical waveguide layer side by the light reflective layer adjacent to the active layer, a large light emission spot can be obtained and a high output light beam can be emitted.

Title: Optical type rotary encoder
Inventor: KAWAMOTO MUTSUMI
IPC: G01D5/36
Filed: 1985-12-28
Abstract: PURPOSE:To enable the measurement of an angle of rotation such as torsion angle or the like of a driving shaft accurately in oil within a transmission, by obtaining a reference voltage for correction from an output of one light emitting/receiving element couple to correct an output of the other light emitting/receiving element couple. CONSTITUTION:In the use in the air, a maximum output obtained from a light receiving element 17 and a specified output corresponding to a voltage difference from a voltage when light is shielded are obtained from an amplification circuit 18 and applied to comparator circuits 12 and 13 as a reference voltage. In the use in an oil, the outputs obtained from light receiving elements 8 and 9 will be reduced, the maximum output from a light receiving element 17 decreases, resulting in a less reference voltage from the amplification circuit 18. As a result, a pulse output the same as that in the use in the air can be obtained from comparison circuits 12 and 13. Regardless of a drop in the light transmitting rate and of decrease in the quantity of light to the light receiving elements in the oil, a pulse output by a light passing through slits 31, 32, 4 and 5 is obtained accurately thereby enabling the measurement of an angle of rotation.

IPC: G02B6/30
Filed: 1989-11-20
Abstract: PURPOSE:To increase fusion strength by using quartz glass formed by adding F to the clad glass of an optical fiber to be fused. CONSTITUTION:The optical fiber consisting of the quartz glass added with F in the clad glass is used as the optical fiber to be fused. If the F is added to the clad glass of the optical fiber, the softening temp. thereof is nearly equal to the softening temp. of the glass forming the quartz glass waveguide 32. The glass for the waveguide and the clad glass of the optical fiber in the butt part of the optical fiber formed by adding the F to this clad glass and the quartz glass waveguide 32 are, therefore, heated nearly simultaneously up to the softening temp. and are uniformly fused if this butt part is irradiated with a CO2 laser beam after the above-mentioned optical fiber and waveguide are butted against each other and are brought into pressurized contact with each other. The optical fiber and the glass waveguide are connected with the considerably increased fusion strength in this way.

Abstract: PURPOSE:To provide an expressing method for a conjuncture normal form which reduces a storage area for storing the output result. CONSTITUTION:A certain fixed order is defined concerning all the literals. A set S of product terms is classified into two partial sets S0 and S1 corresponding to whether a certain literal (t) is contained or not concerning the set S of product terms. According to the literal order, this processing is recursively repeated to the set of product terms contained in the conjuncture normal form concerning all the literals, a logic value '0' is allocated to the empty class, and a logic value '1' is allocated to the non-empty class. A bisected tree is generated by using intermediate nodes of respective literals, two branches expressing the presence/absence of respective literals and terminal nodes expressing the logic values '0' and '1'. When any equivalent branches are existent in this bisected tree, those branches are shared. When a node, for which two branches instruct the same destination, is existent, that node is eliminated, and branches are directly linked.

Filed: 1991-11-15
Abstract: PURPOSE:To readily produce a haloalkanoyl isocyanate having various uses as an industrial raw material for production by reacting acrylamide with an oxalyl halide, especially oxalyl chloride. CONSTITUTION:An acrylamide (e.g. methacrylamide) expressed by formula III (R is H or lower alkyl) is reacted with an oxalyl halide (oxalyl chloride is especially preferred) expressed by the formula (COX)2 (X is halogen), preferably at (1-0.5):1 molar ratio to provide a haloalkanoyl isocyanate expressed by formula II (e.g. alpha-methyl-beta-chloropropionyl isocyanate). Since the haloalkanoyl isocyanate is normally a stable liquid at ordinary temperature, it is readily handleable and easily usable as a solution due to its solubility in various organic solvents. If the aforementioned haloalkanoyl isocyanate is allowed to stand under natural conditions, it reacts with moisture to readily afford amides. Thereby, it has advantages in low environmental pollution or residual properties. Furthermore, the above-mentioned compound is also useful as a raw material and an intermediate, etc., for producing medicines, agricultural chemicals, dyes, etc.
