IPC: H01S5/00
Filed: 1987-02-13
Abstract: PURPOSE:To obtain the stable light-coupling efficiency between a light-emitting device and an optical fiber always in the highest state by a method wherein a stem, an optical-fiber support part and a fiber-guide support part are molded as one unit. CONSTITUTION:A light-emitting device, a device support part where the light- emitting device is mounted, an optical fiber 11, an optical-fiber support part 30, a fiber guide 9 and a stem 3 are provided; the tip of the optical fiber 11 faces the radiating face of the light-emitting device. The optical-fiber support part 30 supports the optical fiber 11 in order to maintain the position of the tip part of the optical fiber; the fiber guide 9 into which the optical fiber is inserted fixes this optical fiber; the stem 3 where various components are mounted fixes these components. Furthermore, one part of the stem 3 protrudes so as to form an optical-fiber support part 3e; the circumference of the stem 3 protrudes partially so as to form a fiber-guide support part which supports and fixes the fiber guide 9. By this setup, it is possible to obtain a lightemitting device, equipped with an optical fiber, whose light output is not influenced by the temperature and which can maintain the stable light-coupling efficiency.

Title: Robot controller
Inventor: OSAKI HIDEYA
IPC: G05B19/42
Filed: 1992-02-17
Abstract: PURPOSE:To increase the shape data without complicating a robot controller by separating the basic articular angle and the rotational frequency from each articular angle and calculating a basic shape code and an extension shape from the separated articular angle and rotational frequency. CONSTITUTION:A separator 11 separates the basic articular angle and the rotational frequency from each articular angle of a robot arm. A basic shape code computing element 12 calculates a basic shape code from the basic articular angle. An extension shape code computing element 13 calculates an extension shape code from the basic shape code and the rotational frequency and stores this calculated code in a teaching data memory 4. A mechanism adverse conversion computing element 5 calculates a combination of articular angles that can be acquired from the position/attitude data on the arm fingers given from a mechanism forward conversion computing element 2. An extension articular angle computing element 15 selects a correct combination of articular angles with the basic shape code produced from the extension shape code and outputs an extension articular angle based on the rotational frequency. A comparator 8 outputs an error signal if no coincidence is obtained between the basic shape code and the basic shape code separated from the present extension shape code.

Title: Mask for far ultraviolet exposure
Inventor: KAWAMURA NOBUKI
IPC: G03F1/00
Filed: 1979-03-14
Abstract: PURPOSE:To provide the title mask having low reflectance and causing no hazy outlines of an exposed pattern by forming a reflection preventing film of a metal oxide or a metal fluoride which is transparent or translucent to far ultraviolet light on a metal thin film mask pattern. CONSTITUTION:On substrate 1 of transparent quartz or the like mask pattern 2 of metallic chrominum thin film or the like which is opaque to far ultraviolet light is set, and on pattern 2 about 200-400Angstrom  thick reflection preventing film 7 of a metal oxide such as aluminum oxide or chrominum oxide or a metal fluoride such as magnesium fluoride which is almost transparent to far ultraviolet light is formed. At this time, the thickness is regulated to 1/4 of the wavelength (200nm) of far ultraviolet light used in exposure. Thus, light 8 reflected from film 7 and light 9 reflected from the surface of mask 2 are delayed by about 90 deg. in phase, so they are cancelled each other to reduce the quantity of light 9, thereby minimizing an error in measurement in forming a pattern due to penetration of light into unexposable region 6 of resist film 4.

Title: Type area protecting treatment method of negative type lithographic printing plate
Inventor: KIMURA TAKESHI
IPC: G03F7/32
Filed: 1995-02-17
Abstract: PURPOSE: To prevent the inking properties of an image part from deteriorating and make it hard to be stained, by a method wherein compound having pivaloyl group is included in diazo type negative type lithographic printing plate and further treated with type are protecting agent having the specific domain in the neighborhood of neutrality. CONSTITUTION: After development, a negative type lithographic printing plate containing diazo resin is added with pivaloyl group-containing compound and further treated with type area protecting agent having the pH of 4.5-10. By employing the sensitizing agent having pivaloyl group, the residual film after development becomes much and unreacted diazo resin in the residual film becomes also much. Thus, the diazo resin and the oil component in ink reacts each other so as to adhere to the non-image part of the plate, resulting in developing stain. Therefore, by using the type area protecting agent having the pH of 4.5-10, the diazo resin left on the plate is quickly dissolved, resulting in preventing the reaction between the diazo resin and the oil component in the ink from occurring.  Thus, the inking properties of the image part does not deteriorate and protective treatment, which is less apt to be stained, can be carried out.
