Patent JP-H03189612-A (JP)
Title: Optical collimator and optical sensor using this collimator
Inventor: KURATA NOBORU
IPC: G01J1/02
Filed: 1989-12-19
Abstract: PURPOSE:To emit collimated beams of light always parallel with the central axis of a rod lens even if misalignment arises between an optical fiber and the rod lens by projecting the light incident end face of the rod lens in the direction of the optical fiber by as much as the circumferential surface approximately equal to the core diameter of the optical fiber with the central axis as a center. CONSTITUTION:The core diameter of the optical fiber 11 and the size of the projecting plane 15 are approximately equal if the optical fiber 11 correctly faces the projecting plane 15 on the central axis 13 of the rod lens 12; therefore, all the light rays 17 emitted from the optical fiber 11 are made incident on the inside of the rod lens 12 from the projecting plane 15 and are emitted as the collimated beams 18 of light parallel with the central axis 13 from the exit end face 16 of the rod lens 12. The incident light 19 on the inside of the rod lens 12 from the projecting plane 15 is emitted as the collimated beams 21 of light parallel with the central axis 13 from the exit end face 16 if the axial misalignment arises between the optical fiber 11 and the central axis 13 of the rod lens 12; whereas, the light 20 directing toward the end face 14 existing in the position apart from the projecting plane 15 is scattered or absorbed therein and becomes the loss of light.

IPC: B23K3/04
Filed: 1987-12-25
Abstract: PURPOSE:To improve the quality of a reflow soldering by providing an inside nozzle blowing a high temp. hot blast and arranging an outside nozzle blowing the hot blast of lower temp. than that of the inner side nozzle at the outside thereof. CONSTITUTION:The inside nozzle blowing a hot blast H1 appropriate for hot blast reflow soldering is provided and at the outside thereof the outside nozzle 11 blowing the hot blast H2 proper for preheating a creamy solder is arranged. The reflow soldering of a lead part 4a is executed with blowing the hot blast H1, H2 respectively from the inner and outer nozzles 10, 11 by moving a supporting base 6 by using a robot hand 9. The soldering of a stabilized temp. curve is executed without lowering a preheating effect by the hot blast H1 of the inner side nozzle 10 after blowing in advance the hot blast H2 by the outer side nozzle 11. The quality in soldering is thus improved because the forming, etc., of a solder ball are prevented.

Title: Manufacture of aggregation
Inventor: ASANO YASUHIRO
IPC: B27M3/00
Filed: 1994-12-12
Abstract: PURPOSE: To provide a method of manufacturing a high-quality aggregation at a low cost by preventing the internal tissue of an aggregation from breaking down to improve its quality, and realizing highly efficient operation and the easing of maintenance services for a manufacturing device by employing two independently separate units of a manufacturing device instead of a single unit for the enhancement of mass- productivity. CONSTITUTION: Each lumber from thinning is dried in a state that a die 42 is held at a specified compressibility, in a compression-molding device 40. Consequently, the moisture content of each lumber from thinning is reduced to set it in a specified shape temporarily. The temporarily set lumber from thinning is thermally treated by vapor under high pressure using a permanently setting device, so that the specified shape is set permanently. The internal tissue of an aggregation is prevented from breaking down by thermal treatment at a low moisture content rate. In addition, it is possible to simplify the device for treating each lumber from thinning 2 because it is treated by two independently separate units instead of a single unit as the compression-molding device 40 and the permanently setting device.  Besides it is possible to enhance the thermal efficiency significantly, reduce the operating volume and maintenance services, and utilize the existing equipment.

Filed: 1990-11-29
Abstract: PURPOSE:To know the position of an optical means even when the optical means is moved by the vibration or the impact in the case of transportation by detecting any of specified number of discrimination patterns and discriminating the position of the optical means. CONSTITUTION:When a detection means 25 detects a pattern 28a, it is discriminated that a rod lens array 2 exists on the right side from the central part of its moving area and in a non-copying area which is deviated from a position opposed to an aperture part 1a. In such a case, a photosensitive material 17 is not exposed, so that copying is performed by returning a carrier 3 to the right side at the time of next copying. In the case of detecting a pattern 28b, it is discriminated that the array 2 exists in a copying area opposed to the aperture 1a and on the right side from the central part. In such a case, since there is possibility that the photosensitive material 17 is exposed, a warning is given. In the case of detecting a pattern 28C, the same processing as in the case of detecting the pattern 28b is performed, and in the case of detecting a pattern 28d, the same processing as in the case of detecting the pattern 28a is performed.

Title: Deflashing equipment
Inventor: ONODERA YUTAKA
IPC: B26F3/06
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To keep the temperature of combustion gas blown against a workpiece at a prescribed one at all times and to enable removal of a flash sticking to the workpiece, by melting at a proper temperature at all times, by a method wherein a gas jet nozzle blowing the combustion gas against the outer peripheral part of the workpiece from a prescribed distance at all times is moved in accordance with a cam follower. SOLUTION: A gas jet nozzle 14 is moved relatively and analogously to the shape in plane of a workpiece 51 supported by a rotating part 1 and rotated at a prescribed position and a distance between the workpiece 51 and the gas jet nozzle 14 is kept fixed constantly during one rotation of the workpiece 51. Accordingly, the temperature of combustion gas blown against the outer peripheral surface of a fusion-bonded part 54 of the workpiece 51 can be kept prescribed at all times and thereby a flash sticking to the outer peripheral surface of the fusion-bonded part 54 can be removed by melting at a proper temperature at all times.  Besides, this method is excellent in practicability and general-purpose properties, since a relatively expensive robot is not needed for attaining such an operation as the above, and moreover the safety for an operator is ensured, since a deflashing operation is mechanized and is not conducted manually.
