Title: Light wavelength converting device
Inventor: SEKIGUCHI YOSHINOBU
IPC: H01S5/0625
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain the device which can operate fast and consists of a small number of components and is then simple in constitution by using a semiconductor laser which has a periodic structure in a waveguide so that an active layer has a gain nearly equal to independent polarization modes. SOLUTION: The semiconductor laser 1 whose active layer has the periodic structure in a waveguide and also has a gain nearly equal to the two independent polarization modes is used for a wavelength conversion part. When polarized light of input light 4 is placed in polarization mode different from that polarization mode that the semiconductor laser 1 oscillates in by a polarization control element 3 and inputted to the semiconductor laser 1, oscillation in the polarization mode of the input light 4 is caused and the mode of the starting oscillation is suppressed, so that the oscillation stops. Therefore, the output light of the semiconductor laser 1 is switched between the polarization of the input light 4 and the polarization orthogonal to it corresponding to the ON/OFF state of the input light 4.  For the purpose, the polarization mode different from the input light is obtained as output light 6 by a polarized light selecting element, so that the wavelength can be converted.

Title: Reproducing device
Inventor: HASHIRANO MASARU
IPC: G11B5/027
Filed: 1990-06-13
Abstract: PURPOSE:To obtain a clearly reproduced picture even when 'clogging' occurs in one head by alternately executing write and read during a period, in which a reproduced output is higher than a prescribed level, in a memory means and executing only read during a period when the reproduced output is lower than the prescribed level. CONSTITUTION:A memory device 105, selecting means 106, memory control means 107 and select signal preparing means 108 are provided as new constitutive elements. In this case, while the reproduced output is higher than the prescribed level, the memory device 105 alternately executes write and read and while the reproduced output is lower than the prescribed level, the memory device 105 executes only read. Then, when any output cannot be obtained from one head, it is complemented by writing thetoutput of the other head, from which the normal reproduced output can be obtained, into the memory device 105 and reading the contents of the memory device 105 out. Thus, even when one head is not operated, the clear reproduced picture can be obtained by using the other head.

Title: Lapping device of gear set
Inventor: IMAI SHUICHI
IPC: B23F19/02
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To correct the pitch error or gear tooth form error with high efficiency by imparting a rotating phase difference between mutually engaged gears to generate a meshing surface pressure. SOLUTION: A controller 13 continues the synchronous rotation while holding a phase difference between a pinion gear 2 and a ring gear 3 in a target value. Thus, the gear surfaces of both the pinion gear 2 and the ring gear 3 are lapping processed. The pinion gear 2 and ring gear 3 mass-worked have a minute pitch error or gear tooth form error. Therefore, they generate an advance or a delay by the portion of the error to the rotating directional gear tooth flanks. Since the quantity of returning to a prescribed phase angle is larger in the rotating directional advance parts of the gear tooth flanks, a higher lapping torque is received from a servo motor 12 to more strongly work the advanced gear tooth flanks.

Filed: 1986-07-03
Abstract: PURPOSE:To easily form a tungsten reinforced composite material by inserting and holding a brazing filler metal between plural iron base alloy sheets which have contained at least one layer consisting of a tungsten wire, and heating and holding it. CONSTITUTION:A brazing filler metal such an aluminum plate, etc. is inserted and held between plural iron base alloy sheets which have contained at least one layer of layers consisting of a tungsten wire.

Abstract: PURPOSE:To perform improved overlap recording and to obtain a recording image improved in color reproducibility, by constituting thermal transfer image receiving paper of a base film and the ink receiving layer applied to the base film and forming a capillary structure comprising air bubbles in the ink receiving layer. CONSTITUTION:An ink receiving layer 3b is applied to a base film 3a to constitute thermal transfer image receiving paper 5.

Title: Pre-coder
Inventor: HIGURE SEIJI
IPC: H03M5/14
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a pre-coder which can perform pre-coding so that the same value is not continued for several bits or more (especially, the same value is not continued in an important part such as ID or the like) even if the same value is continued for the prescribed bits or more in input data. SOLUTION: An inverter 12 converts input data to be recorded or transferred into an inverse logic value. An adder 2 adds output data of the inverter to output data of a delay circuit 5, and outputs pre-coded data to an output terminal 6 and the delay circuit 5 through a changeover switch 3. The changeover switch 3 switches and outputs a synchronizing signal Sync from an input terminal 4. The delay circuit 5 delays pre-coded output data by a prescribed time and outputs it to the adder 2. Even when 16 bits of input data are all '0' and a value of the last two bits of the synchronizing signal Sync is set to '00', a pre-code output in which the same value is not continued beyond two bits can be obtained.

Title: Infrared detector
Inventor: HIKITA SOICHIRO
IPC: G01J5/02
Filed: 1988-06-22
Abstract: PURPOSE:To reduce crosstalk, to improve space resolution and to lower the resistance of a substrate by providing a picture element separation band consisting of a specified area between respective picture elements. CONSTITUTION:The picture element separation band 7 consisting of the Hg1- yCdTe area (x>y>=0) is provided between the respective picture elements E of photodiodes, in an array shape, made of HgxCdxTe. In such a constitution, if Cd is reduced, the width of a band gap (forbidden band) in an energy band becomes narrower and the recombination of carrier occurs in the picture element separation band 7, so that it is difficult for generated carrier to flow into the adjacent picture element. Then, the crosstalk can be reduced and the space resolution can be improved. Since the Hg1-yCdyTe area where Cd is reduced becomes low resistance, the voltage drop can be decreased. Thus, the space resolution can be improved and the resistance of the substrate can be lowered.

Abstract: PURPOSE: To save machining and perform beveling of a joined part by heating the butt angle parts of welded strip and melting the same.  
     CONSTITUTION: The respective end parts of the 1st strip 10 and the 2nd strip 11 thicker than the strip 10 are butt welded, and the butt angle part of the strip 11 is heated to melt.

Title: Quantitative analysis of nitrododecane

Abstract: PURPOSE:To analyze nitrododecane with high sensitivity by drawing a nuclear fuel retreating solvent contg. the nitrododecane, adding aqueous hydrogen thereto, thermally cracking the same in the presence of a nickel catalyst and subjecting the generated ammonia to amperometry. CONSTITUTION:The nuclear fuel retreating solvent 2 essentially consisting of tributyl phosphate and contg. the nitrododecane is kept run in a line 1. The solvent is sampled from the line 1 and the sample is put into a cracking vessel 7. The nickel catalyst is preliminarily added to the cracking vessel 7 and the gaseous hydrogen 8 is introduced into the cracking vessel 7 to thermally crack the nitrododecane and to generate ammonia. The ammonia is detected by an amperometric detector 11 by which the concn. of the nitrododecane is quantita tively determined. The nitrododecane is, therefore, detected at <=about 200ppm and the conditions for operating the distillation of the solvent are adjustable. The performance of the nuclear fuel extracting solvent is thus maintained.
