Title: Method for soldering by laser
Inventor: KASHIWARA TAKAO
IPC: B23K1/005
Filed: 1986-01-22
Abstract: PURPOSE:To improve the positioning accuracy by positioning a semiconductor element by moving it by a robot, by a shift quantity of a reference line of the semiconductor element and a target line of a mounting surface, calculating the shift quantity again by a computer, etc., and confirming whether the positioning is correct or not. CONSTITUTION:By moving a robot 7, a semiconductor 1 is placed on a mounting surface 5 so that a center (c) and a reference line (w) of the semiconductor element 1 conform with a target point (s) and a target line (u) by a computer 9 which has calculated and stored a shift quantity. The semiconductor 1 is held by a vacuum chuck 2 and soldering is executed by laser light. However, when there is a shift in the position relation, it is brought to an image pickup by a television camera 3, and by a data which has been calculated by an image processor 10 and the computer 9, a difference between the reference line (w) and the target line (u) is calculated. Therefore, such a moving extent (x and y directions) and a rotation quantity as (w-u) becomes '0' are calculated. Based on the calculated value, a robot controller 8 drives the robot 7, and replaces the element 1 which has been held by the vacuum chuck 2 so as to conform with the target point (s) and the target line (u).

Filed: 1981-02-02
Abstract: PURPOSE:To reduce length and thickness of a stabilizer bar by fixing its one end to one of trailing arms and the other end to the middle of an accelerator beam. CONSTITUTION:An accelerator beam 4 is positioned in the vertical and longitudinal directions by means of a pair of trailing arms 6, 6 and also positioned in the lateral direction by means of Panhard rod 5.

Title: Automatic routing table generating system for exchange
Inventor: HIRATA NAOYUKI
IPC: H04Q3/545
Filed: 1991-02-04
Abstract: PURPOSE:To grasp the constitution of a network, to calculate the shortest route and to automatically revise the routing table by sending receiving a network constitution information notice of each exchange. CONSTITUTION:An exchange A receives information (network constitution information) of an exchange adjacent to an exchange D from the exchange D to check the presence of a path (a) of the exchange A and saves a route d a and a link number 1 to a work area when the path (a) is in existence. Then the presence of the path (a) is checked from the network constitution information of the exchange B adjacent to the exchange D and when the path (a) is in existence, a route d b a and a link number 2 are saved in the work area. Similarly, a route d c a and a link number are saved in the work area based on the network constitution information of the adjacent exchange C. Thus, based on the information of the adjacent exchange to the exchange D, the network constitution information received from each exchange is analyzed and the route up to the exchange A is traced one by one and saved to the work area. Then the sequence of the route is decided based on the shortest link number and set to a routing table.

Abstract: PURPOSE:To offer a spread forging equipment by which the cost of equipment of a mold and the operation maintaining cost, by providing a forging device provided with the upper and lower metallic dies whose angle can be adjusted obliquely against the width direction of a rolled stock, and a rewinding machine or a winding machine. CONSTITUTION:A spread forging equipment is constituted of a forging device 3 of the downstream of a continuous casting machine 1 and a winding machine 2. The forging device 3 allows the upper and lower metallic dies 4, 5 to execute a reciprocating motion in the upper and lower directions and the line direction by rolling down devices 8, 9 and a reciprocating device. When a rolled stock 37 is allowed to pass through between the moving metallic dies 4, 5, the rolled stock 37 goes into the metallic dies 4, 5 at an angle theta. Accordingly, the rolling material 37 is refracted by the angle theta against the direction where it has gone into the metallic dies 4, 5, and width W2 of the rolled stock 37 after rolling becomes wider than width W1 before rolling. Even in the case of a rewinding machine provided at a feed angle theta against the metallic dies 4, 5, on the upstream side of the forging device 3, the processing is executed in the same way as the forging. In such a way, the cost of equipment of a mold and the operation maintaining cost can be curtailed remarkably.

Title: Post header
Inventor: ENOMOTO IKUO
IPC: H01R9/16
Filed: 1989-01-23
Abstract: PURPOSE:To generate a holding force by a projection and to suppress the accumulative size error by forming a projection and a recess at the pressing-in part of a contact, and pressing in the contact to the hole of a housing to make the projection square to the lining-up direction. CONSTITUTION:At the pressing-in part 2c of a contact 2, a recess 2d is formed in the direction that numerous contacts are lined up. And, in the direction square to the lining-up direction, a projection 2e is formed. And a projection 3b to gear with the recess 2d is formed to prevent a large deformation by pressing in the contact 2. The hole 3a of a housing 3 in the direction square to the lining-up direction is formed making its diameter narrower than that of the projection 2e of the contact 2. As a result, when the contact 2 is pressed in to the hole 3a, it is depressed to respond to the form of the projection 2e, and a holding force is generated thereby. When a force to pull out the contact 2 acts against the holding force, the projection 3b geared to the recess 2d reinforces the holding force, acting as a large resistance.

IPC: H03H9/19
Filed: 1983-01-31
Abstract: PURPOSE:To control the frequency with high efficiency even with a microminiature oscillating plate by providing continuously an electroplating foundation electrode to an exciting electrode. CONSTITUTION:An oscillating plate 21 is unified with a support part 22 and contains an exciting electrode 23 together with an electroplating electrode foundation electrode 24 which is formed continuously to the electrode 23 at both ends of the plate 21. Such an oscillator is dipped into a plating solution together with a counter electrode made of a plating metal, and the DC voltage is applied between the electrode 24 and the counter electrode. Then an electrode material is attached on the surface of the electrode 24, or otherwise the polarity is inverted. As a result, the electrode material is eluted to increase and decrease the mass. Thus the frequency can be controlled. In such a way, the electrode material is evenly increased and decreased with addition of the electrode 24. This ensures the easy control of frequency even with a microminiature oscillator.
