Title: Pressure welding equipment by resistance heating
Inventor: SAITOU YUUJI
IPC: B23K11/02
Filed: 1984-04-27
Abstract: PURPOSE:To subject a material to be pressure-welded having a small natural resistance to the heating and pressure welding with less electric power for quality improvement by constituting a clamping tool with an electrode supporter of the material having a small natural resistance and an exothermic supporter of the heat resisting hard material having a big natural resistance. CONSTITUTION:A clamping tool 5 is electrified via a cable 4 from a power source transformer 3 and an electric current is passed to an exothermic supporter 5b and a material to be pressure-welded 1 via an electrode supporter 5a. The exothermic supporter 5b is easy in generation of heat by electrifying and prevents the out-flow of heat from the pressure welded face of the material to be pressure-welded to the electrode supporter 5a and raises the temp. in short time with less electric power. At the time when the temp. of the pressure welded face of the material 1 to be pressure-welded is raised the electrifying is suspended and simultaneously the material 1 to be pressure-welded is pressure-welded by moving one of the clamping tool 5 to pressure-welding direction with a hydraulic mechanism for giving a pressurizing force. The flowing metal caused at the time of pressure welding of the material to be pressure-welded is removed by the exothermic supporter 5b consisting of heat resisting hard material.

Title: Manufacturing code wheel of encoder
Inventor: TAKAHASHI YOSHIHIRO
IPC: G01D5/245
Filed: 1985-04-22
Abstract: PURPOSE:To improve the balance an SN ratio by depositing a desired magnetic metal in minute holes in an alumite on the surfaces of projected strips by means of an electrolysis in the solution of the magnetic metal. CONSTITUTION:A work rod 2 is obtained by extruding a round bar 1 with dies constructed to a prescribed shape. Thereafter, an alumite film 5 on the surfaces of projected strips 3 is removed by a turning and another alumite film 5a is formed again as a sealing process is applied only to grooves 4. Then, the work rod 2 thus processed is electrolyzed in a solution in which a desired magnetic metal is solved and, since material aluminum is conductive whereas the alumite is nonconductive, the magnetic metal 8 is deposited in a longitudinal direction in minute holes 6a in the novel alumite film 5a. Thus, a magnetic field intersects the central axis of a code wheel at right angles, enabling the balance of an SN ratio to be improved.

Abstract: PURPOSE:To collect wafers without damages by providing a rotating mechanism which is closely placing a rod in contact with a lap panel through rotation of such rod with the pivoting part set as the fulcrum and is exfoliating the wafer being attracted to a vacuum attracting plate from the lap panel. CONSTITUTION:After lapping of wafer 16, the upper lap panel is raised and a carrier 17 is stopped at the specified position. An arm 1 is then moved so that a cylindrical body 2 and the carrier 17 are placed coaxially. Moreover, the cylindrical body 2 is rotated by transferring a belt 3 until a vacuum attracting plate 11 supported by a support arm 4 is located just above the wafer 11. The vacuum absorbing plate 11 is caused to atrract the wafer. The rod 7 rotates about the pin 6 considered as the fulcrum and thereby the vacuum attracting plate 11 is lifted upward. At this time, the wafer 16 is closely placed in contact with the lower lap panel 18 but it is exfoliated with a small force owing to the principle of rod. When the wafer 16 is exfoliated from the lap panel 18, the wafer moves up to the wafer placing board while it is vacuum-attracted to the vacuum attracting plate 11, thereafter, the attracting operation is released.
