Title: Photoelectric smoke sensor
Inventor: YAMAMOTO TAKESHI
IPC: G08B17/107
Filed: 1986-06-30
Abstract: PURPOSE:To improve the detection accuracy of smoke concentration with simple constitution by employing narrow structure for a smoke flow passage and providing a detecting function which compares the quantity of light increasing owing to the presence of smoke with the decreasing quantity of light. CONSTITUTION:A narrow passage is formed as the smoke flow passage 9 which connects a smoke entrance space 6 and a smoke exit space 8 to each other and a light emission part 10 and the light reception part 12 consisting of the 1st - the 3rd light receiving elements 13 - 15 are arranged across the flow passage 9. A shield body 16 which cuts off the optical coupling path from the light emission part 10 to the element 14 and does not cut off the optical coupling path to the elements 13 and 15 is provided in the center of the passage 9, and the photoelectromotive voltage of the element 14 which detects the quantity of light scattered by nearby smoke particles is compared with the mean value of photoelectromotive voltages of the elements 13 and 15 which detect the quantity of transmitted light and perform temperature compensation to detect the smoke concentration Thus, the passage 9 is narrowed down to increase the photoelectromotive voltage of the element 14 and decrease the photoelectromotive voltages of the elements 13 and 15 which receive transmitted light, and detection accuracy with a high SN ratio is obtained in the calculation of the concentration based upon the difference between the photoelectromotive voltages as a factor even when the smoke concentration is low.

Title: Electroforming electrode device for electrical discharge machining
Inventor: ASHIO EIJI
IPC: B23H1/02
Filed: 1978-12-13
Abstract: PURPOSE:To interrupt electric discharge machining immediately at a point when a peel formed to grow on an electrode block is quickly detected during the conduct. CONSTITUTION:A main shaft 6 of an electric discharge machine extends down to an end of an electroforming electrode A attached and is elevated freely by a column 7. If in electrodischarge machining, a peel 4 may be formed partially on an electrode block 1 of an electrode A to grow, the peel 4 discharges electricity to remove specified metal from a workpiece 3. As a growing speed of the peel 4 is faster than a lowering speed of the main shaft 6, the main shaft 6 turns to be lifted gradually. The main shaft 6 goes upward until a permanent magnet 8 is removed from a contact switch 9 of a sensor OFF. Immediate interruption of electric discharge machining resulting can prevent production of defective workpiece 3.

Title: Wirebonding
Inventor: MIYAJIMA KENJI
IPC: H01L21/603
Filed: 1978-12-13
Abstract: PURPOSE: To eliminate poor bonding, by contacting a capillary that encloses gold wire, which is piercing through the inside thereof, to a material-to-be-bonded in a wire bonding process, and by tilting the capillary or the material-to-be-bonded by 2°W6° from the direction of drawing-out of the gold wire.  
     CONSTITUTION: A capillary 1 that encloses a lead wire 3 comprising gold wire and the like, which piercing through the inside thereof, is contacted to the material-to- be-bonded 2 and heated, thereby the wire 3 is fixed to the surface of the material- to-be-bonded 3. In this step, the capillary 1 does not make a right angle with the material-to-be-bonded 2, but is tilted by 2°W6° from the perpendicular P to the direction of drawing-out of the wire 3, and is compressed. In this method, the wire 3 can be completely squashed with the tip of the capillary 1, thereby poor bonding can be eliminated and the yield rate is enhanced. Or, the material-to-be-bonded 2 may be tilted in stead of tilting the capillary 1.
