Abstract: PURPOSE:To obtain a device for automatically installing electronic components which can make the chip center of a component always coincide with the normal position of a mounting station whichever positioning unit is used for positioning by a method wherein the position of an attracting a nozzle is taken as a reference position and correction data are produced based upon the discrepancies of the respective positioning units from the reference position and an X-Y table is controlled to shift to X- and Y-directions in accordance with the correction data before the component is installed on a board. CONSTITUTION:When the positioning centers of the respective positioning units 81-85 in respective positioning stations D-F come to a mounting station M, discrepancies between the positioning centers D1, E1 or E2 and F1 or F2 of the respective positioning units and the nozzle center O of an attracting nozzle 21 are optically read and data to be corrected are produced. NC data of a control system and the correction data are stored in respective memories and counters by key-input. Then an X-Y table 5 is controlled to shift to X- and Y-directions before a component is installed on a board. With this constitution, the chip center of the component is always made to coincide with the normal position of the station M.

Abstract: PROBLEM TO BE SOLVED: To save cost and make the thickness ratio of both steel plates free by forming a center plate for separating a cathode gas and an anode gas by pressing metal molds against both surfaces of piled nickel steel plate and stainless steel plate. SOLUTION: A center plate 8 constituting a separator is formed by piling up a nickel steel plate 10a and a stainless steel plate 10b, interposing them between an upper metal mold 11a and a lower metal mold 11b, then pressing. When trapping air is anticipated between both steel plates 10a, 10b, air exhaust holes are formed in suitable portions, and closed by welding or the like after the center plate 8 was formed.

Abstract: PURPOSE:To aim at a reduction in the number of parts items as well as an increase in braking force, by constituting an operating shaft member consisting of a cam part and a pin part in a way of setting up it rotatably between both ends of a pair of brake shoes, in case of the above-captioned brake for small vehicles including a motorcycle or the like. CONSTITUTION:With a brake operated, when each of operating shaft members 3 and 3' is rotated, cam parts 3a and 3'a expand the plane surface part of each of toe side end parts 4a and 4'a of brake shoes 4 and 4' to the outside of a brake drum circumference. With this outward expansion, these brake shoes 4 and 4' forcibly presses the inner circumferential surface of a brake drum 1 with each of pin parts 3b and 3'b of the other side operating shaft members 3 and 3' being rotatably engaged with end parts 4b and 4'b at the heel side and thus performs braking a car. With this constitution, each of clearances l and l' between the toe side end parts 4a, 4'a and the heel side end parts 4b, 4'b becomes narrowed, and each of brake linings 5 and 5' also is able to grow long toward these operrating shaft members 3 and 3' whereby a frictional area can be increased in length. Therefore, braking force can be increased despite such a simple constitution.

Title: Motor-driven tool
Inventor: TANAKA TORU
IPC: B23D29/00
Filed: 1989-08-25
Abstract: PURPOSE:To reduce the weight of a motor-driven tool by installing a load current detecting means which detects the load current of a motor, and a rise detecting means which outputs detected signal to a rotational direction control means when a rise of the load current detected by the load current detecting means is detected. CONSTITUTION:Electric power is supplied by a power supply means 1 to rotate a motor 22, and a cutter part 12 starts cutting a reinforcing bar. As a result, the load current detected by a load current detecting means 3 starts to rise because of the increase of load applied to the motor 22. When the cutter part 12 cuts the reinforcing bar to a certain extent, the load current comes to be maximum, and then the load current starts to decrease. The rising timing of the load current is detected by a rise detecting means 4, and the detected signal is outputted to a rotational direction control means 2. When the detected signal is inputted to the rotational direction control means 2, the rotational direction control means 2 reverses the rotational direction of the motor 22 to separate the cutter part 12 from the reinforcing bar.
