Title: Method for hydrolyzing amino acid esters
Inventor: HIBINO HIDEHIKO
IPC: C12P13/04
Filed: 1989-02-16
Abstract: PURPOSE:To readily enable obtaining of amino acid esters under mild conditions by carrying out reaction using a lipase as a reaction catalyst. CONSTITUTION:Monoaminomonocarboxylic acids, such as glycine, are reacted with a <=10C alcohol, such as butyl alcohol, to afford amino acid esters, such as glycine butyl ester. The resultant esters in an amount of 1-50wt.% are then dispersed in a buffer solution at a desired pH to provide a raw material dispersion. A lipase, such as derived from a yeast of the genus Candida, in an amount of 1-10000 units (1 unit is the amount of the enzyme liberating fatty acids at 1mumol/min from emulsified olive oil) lipase activity based on 1g raw material is added to the above-mentioned dispersion to provide a reaction solution, which is then reacted at 20-60 deg.C for 3-24hr while being vibrated to hydrolyze the amino acid esters.

Title: Optical recording system and optical recording medium
Inventor: OGAWA KATSUMI
IPC: G11B7/24035
Filed: 1990-02-15
Abstract: PURPOSE:To enable easy rewriting of data in a cheap optical recording medium in which a resin is used for the recording layer, by forming the recording layer from a shape-memory resin and irradiating the recording layer with laser light to form projections according to data. CONSTITUTION:On recording, projections are formed according to data in the recording layer 3 comprising a shape-memory resin by irradiating the layer 3 with laser light. By heating the recording layer to specified temp., the projections are made to disappear for erasing of the data. Namely, recording is performed by irradiating the recording layer 3 comprising a shape-memory resin with laser light to form pits according to data, and these pits are flattened to erase the data by heating the layer 3 to specified temp. Thereby, a cheap optical recording medium in which rewriting of data is possible can be obtained.

Title: Window of laser beam for excimer laser device and excimer laser using the same
Inventor: TSUBOI SHUNGO
IPC: G02B5/26
Filed: 1993-02-24
Abstract: PURPOSE:To prevent contamination of a window for taking out laser beams, to decrease absorption of laser beams, and to improve laser efficiency by giving specified optical characteristics to the window to suppress generation of acitve oxygen. CONSTITUTION:The window for taking out laser beams of an excimer laser device consists of a base body 6 selected from among fluorides of calcium, barium, etc., and a dielectric alternate multilayer film 74 formed on at least one surface of the base body 6. The multilayer 74 consists of a first multilayer group and a second multilayer group. The first multilayer group is produced by alternately depositing a material having >=2.0 refractive index for 248nm wavelength and a material having <=1.5 refractive index for 248nm wavelemength by vapor deposition. The second mutilayer group is formed on the outer surface of the first multilayer group by alternately laminating a material having >=2.0 refractive index for 248nm wavelength and a material having <=1.5 refractive index for 248 wavelength. The optical film thickness of each layer is (0.125 to 0.25) x wavelength, and the difference of designed wavelengths for the first and second multilayer groups is within 10-50nm. The multilayer film has such optical characteristics that the film does not transmit <200nm wavelength region. Thus, generation of active oxygen is suppressed.

Title: Immersion nozzle
Inventor: NAKAJIMA TAKAHARU
IPC: B22D11/10
Filed: 1987-02-17
Abstract: PURPOSE:To prevent clogging of a hole and product defect by disposing a member which contains specific weight % of MgO, C and SiO2 and consists of the balance ZrO2 and impurity to the inside wall surface of a nozzle body essentially consisting of alumina graphite. CONSTITUTION:The member 2 which contains 1-15wt.% MgO, <=20wt.% C, and <=1wt.% SiO2 and consists of the balance unavoidable impurities and ZrO2 is disposed to the inside peripheral wall surface of the nozzle body 1 essentially consisting of the alumina graphite. The SiO2 component of the inside peripheral wall surface member 2 in contact with a molten steel is limited to <=1wt.% and, therefore, the deposition of Al2O3 into the molten steel is greatly suppressed if such nozzle is used as the immersion nozzle for continuous casting. ZrO2, MgO and C components improve corrosion resistance and thermal impact resistance. The clogging of the nozzle hole is thereby prevented and the uneven discharge flow of the molten steel is eliminated. The generation of the defect of the steel as a product is thus prevented.

Title: Device for coupling laser light and optical fiber
Inventor: OKINO KEIJI
IPC: G02B6/42
Filed: 1987-02-20
Abstract: PURPOSE:To permit coupling of laser light and optical fiber without being affected by the spreading angle of the laser light by disposing a combination lens between an exit port of a laser oscillator and objective lens for entering the laser light to the optical fiber. CONSTITUTION:The combination lens 13 is finely adjustable in the distance between lens units 11 and 12. The lens units 11, 12 are respectively installed in the positions apart by the distance twice the distance at which the incident laser light 2 condenses. The incident laser light 2 on the lens 13 emerges exactly symmetrically from the lens 13. Since the lens 13 is disposed at the mid-point of the exit port of the laser oscillator 1 and the objective lens 3 for entering the laser light 2 to the optical fiber 4, the incident state of the laser light 2 on the lens 3 is equiv. to the state in the exit port of the laser oscillator 1. The distance between the laser oscillator 1 and the incident end face of the optical fiber 4 is thereby increased without depending on the spreading angle of the laser light 2. The light receiving state of the same spreading angle and beam diameter as the state of the laser light in the exit port of the laser oscillator is thereby formed at the incident end face of the optical fiber.

IPC: H04Q3/42
Filed: 1989-02-17
Abstract: PURPOSE:To reduce noise in reverse control of feeding polarity by converting a reverse control signal into a slow leading and trailing waveform with a low pass filter. CONSTITUTION:A low pass filter 1 applying a reverse control signal to current switch 3 as a signal with a waveform of slow leading and trailing is provided, and the current switch 3 switches a current from a reference current generating section 2 to apply the result to bias voltage generating sections 4a, 4b. Moreover, a bias voltage from the bias voltage generating sections 4A, 4B is fed through buffer sections 5A, 5B with a low output impedance to a feeding section 6, fed to subscriber lines A, B from the feeding section 6 and reverse control of the feeding polarity is implemented in response to the reverse control signal. Thus, the slow leading and trailing of the reverse control signal is fed to the current switch 3 as the waveform and since the current switching causes smooth change at a start point of time of the inversion of the feeding polarity, then noise is reduced to a negligible degree.

Title: Distributor for ignition of internal combustion engine
Inventor: IMAI IWAO
IPC: F02P7/02
Filed: 1981-03-16
Abstract: PURPOSE:To suppress electromagnetic wave noises in a distributor comprising a rotor electrode and fixed electrodes, by laminating a thin metal sheet and a ceramic insulator sheet on each other to manufacture at least the discharge tip of the rotor electrode and by protruding the insulator sheet. CONSTITUTION:To manufacture a rotor electrode 3, a thin sheet 3A of metal such as stainless steel and a ceramic insulator sheet 3B are laminated on each other so that the insulator sheet is protruded by about 0.2mm. from the thin metal sheet toward a fixed electrode 6. The rotor electrode 3 is mounted on the insulator 4 of a rotor 5 by projections 11 which are heated and calked. As a result, electromagnetic wave noises are suppressed by a precursory discharge effect and a local electric field intensification effect rather than by the firing potential reduction effect of creeping discharge. Since the temperature of the thin metal sheet 3A is made high at the time of discharge, a thermoelectron emission effect is produced to lower the firing potential. This contributes to the suppression of the electromagnetic wave noises.
