Title: Optical inverter device
Inventor: YAMAGOSHI SHIGENOBU
IPC: G02F3/00
Filed: 1989-02-01
Abstract: PURPOSE:To output the inverted signal of an input light signal by transmitting only an oscillation light signal which has its 1st wavelength inverted by the wavelength selection of a wavelength filter part. CONSTITUTION:When a light signal which has 2nd wavelength lambda2 different from the wavelength lambda1 is inputted to a laser part 1, in the oscillation state of the light with the 1st wavelength lambda1, the laser part 1 amplifies the input light signal with the wavelength lambda2 by inductive emission. Consequently, the carrier density in the laser part 1 decreases, the gain decreases, and the oscillation output of the light with the wavelength lambda1 decreases as the gain decreases to obtain the oscillation light with the wavelength lambda1 which is the inverted signal of the input light signal with the wavelength lambda2. The input light signal with the wavelength lambda2 which is emitted by the laser light 1 and the input light signal which has the wavelength lambda1 inverted are selected by a wavelength filter 2 and only the input light signal which has the wavelength lambda1 inverted is transmitted and outputted as an output light signal. Consequently, the output light signal with the wavelength lambda1 is outputted as the inverted signal of the input light signal with the wavelength lambda2.

Title: Preparation of aldehydes
Inventor: OOHARA TAKASHI
IPC: C07C67/00
Filed: 1978-02-27
Abstract: PURPOSE: To prepare aldehydes in high yield in a short process, by the hydroformylation of 2W4C α-olefins with CO and H 2  in the vapor phase under mild conditions, using highly active catalyst comprising a specific rhodium cluster supported on a polar carrier.  
     CONSTITUTION: Aldehydes are prepared by the hydroformylation of 2W4C α- olefins with CO and H 2  in the vapor phase, in the presence of Rh 4 (CO) 12 , Rh 6  (CO) 16  or a mixture thereof as a catalyst. The catalyst is supported on a carrier selected from oxides of Zn, Zr, Cr, Mo, Co and Si, and activated carbon. The reaction pressure is 1W25 atm, and the reaction temperature is 80W180°C.  
     EFFECT: Since the reaction is carried out at low pressure, the lowering of catalytic activity and the loss of the expensive catalyst caused by the condensation of the reaction product on the catalyst can be prevented.

Filed: 1981-02-13
Abstract: PURPOSE:To accurately carry out the end point confirmation of manufacturing time  and inspection of product in good reproducibility and in a short time, by detecting  from transition of a peak temperature accompanied with the evaporation of moisture  by using a thermal analysis of a ripe degree (emulsifying property) of solid oils and  fats such as butter, margarine. CONSTITUTION:A transition of a fusion peak appears near a melting point of solid oils  and fats such as butter, shortening and of a peak of moisture evaporation appears subsequently, is measured by a differential thermal analysis (DTA) or a differential scanning calorimeter (DSC). For example, an apex of moisture evaporation appears at  115 deg.C after a little while the fusion peak of DTA in an unripe sample of margarine  and the apex of the peak of moisture evaporation appears at 92 deg.C immediately after  the fusion peak in a ripe product. Further, the apex of the peak of moisture evaporation is lowered from 115 deg.C to 92 deg.C according to the ripe degree during the time finishing the ripeness. The inspection of the ripe degree in a manufacturing step, an end  point of ripening and the ripe degree of a product, is carried out in a short time for a  small amount of sample by examining the correlation between the ripe degree of an  emulsifying test and thermal analysis classified by the solid oils and fats and by preliminarily knowing the peak temperature by utilizing this phenomenon.

Title: Thick-membrane type gas detecting element
Inventor: HISHII TOSHISUKE
IPC: G01N27/12
Filed: 1980-02-22
Abstract: PURPOSE:To increase adhesiveness of a semiconductor layer to a substrate and also to improve gas-detecting performance, by forming a metallic oxide semiconductor layer by thick-membrane-printing process on an insulating substrate provided with two electrodes, and then by forming a porous membrane on and around the semiconductor layer. CONSTITUTION:On an insulating substrate 4 provided with two electrodes 5, a metallic oxide semiconductor layer 6, which has SnO2 as a principal ingredient, is formed by thick-membrane-printing process. A low-melting-point layer 7, which is printed to a thickness of 1-5mu, is coveringly attached onto top and surrounding of the layer 6. The layers 6 and 7 are baked at the same time at a temperature between 500 deg.C and 900 deg.C, which is the glass crystallizing temperature, to obtain a thick-membrane type gas detecting element. As the porous glass membrane prevents the semiconductor layer 6 from exfoliating from the substrate 1 and also from being exposed to any temperature above 1,500 deg.C at which it is completely sintered, it is possible to improve the sensitivity.

Title: Metal lath and its manufacturing press die
Inventor: IZUHARA TAKAO
IPC: B21D31/04
Filed: 1985-02-06
Abstract: PURPOSE:To eliminate occurrence of cutting at folds by giving a round to connecting parts of longitudinal and lateral strands of a metal lath by forming corners of cutting edges of an upper and a lower punching die being fitted each other in an isosceles frustrum shape into a round and widening a space between top and bottom cutting edges for shearing of cut lines of thin steel plates for metal laths. CONSTITUTION:Corners 6a and 5a of the upper and lower punching dies 6 and 5 being fitted each other in an isosceles frustrum shape are rounded for shearing of cut lines making strands by putting a thin steel plate for the metal lath 10 between the upper and lower dies of a press and shifting the plate step by step. The space 8 between bases of the punching dies 5 and 6 abutting on a part being formed into a longitudinal strand 10a is widened not to shear that part. A fold 10c of each lateral strand 10b is not cut because the round is formed at the fold 10c when the thin steel plate 10 having cut lines is expanded laterally to make a metal lath, so that the metal lath 10 becomes a good product.

Title: System for detecting signals of single frequency
Inventor: HIRATA TAKEHIKO
IPC: G01R23/02
Filed: 1982-02-12
Abstract: PURPOSE:To detect signals in the frequency equal to the carrier or very close thereto from one or several signals by utilizing a modulation system without any carrier. CONSTITUTION:For example, a balanced modulation circuit and a ring modulation circuit are used as a modulation system without carrier. When the carrier of an angular frequency W is subjected to a balanced modulation by a modulated wave of an angular frequency U, upper and lower sideband components of the angular frequencies W+U and W-U respectively are generated. A signal to be inspected is applied to a tuning circuit of a sharp selectivity at tuned to the angular frequency W beforehand to extract an angular frequency component near W. The component is overlapped with upper and lower sideband waves and applied to check to see whether the component of the angular frequency U is within the output thereof. This enables the detection of signals in the frequency equal to the carrier or very close thereto from one or several signals.

Title: Device for inspecting semi-conductor integrated circuit
Inventor: ISOBE TERUO
IPC: G01R31/28
Filed: 1991-01-22
Abstract: PURPOSE:To obtain a device, which can prevent vibration at unnoticed output terminals of a semi-conductor integrated circuit to be inspected, by giving the signal at a specified level, which can cut an output stage transistor of the semi- conductor integrated circuit connected to an external output terminal OFF, as the input signal. CONSTITUTION:In the case that an output circuit of a semi-conductor integrated circuit 4 to be inspected consists of an emitter-follower circuit, the voltage L2 at a high level, which is too high to obtain the voltage between base and emitter necessary for the operation of an output stage bipolar transistor, is supplied from an output means 3 of an inspecting device to an output terminal P, which is unnoticed in the inspection. The output operation of the emitter- follower circuit is thereby restricted to maintain the output transistor corresponding to the unnoticed output under the OFF condition even if the control input thereof is under any condition.
