Title: Insulating film-coated conductor and its production
Inventor: TOKORO HIROKAZU
IPC: H01B13/00
Filed: 1989-04-19
Abstract: PURPOSE:To suppress cracking as much as possible and increase durability by forming a nickel coating layer, a nickel-aluminum alloy coating layer, and an aluminum coating layer on a matrix. CONSTITUTION:The title conductor is composed of a matrix 1 of pure copper or a copper alloy, a nickel coating layer 2 of nickel or a nickel alloy formed on the matrix 1, a nickel aluminum alloy coating layer 3 formed on the nickel coating layer 2, and an aluminum layer 4 formed on the nickel aluminum alloy coating layer 3. The bonding strength of the matrix 1 and the nickel coating layer 2 is high and oxide layer formation becomes rare since the nickel coating layer 2 protects the outer surface of the matrix 1. By this structure, as the whole insulating film-coated conductor 1, peeling off between the matrix 1 and each insulating layer and metal layers due to thermal stress and vibration stress is lessened and durability is improved.

Abstract: PURPOSE:To realize the wireless keyboard device for which it is not necessary to connect to a controller. CONSTITUTION:A read panel 1 generates an AC magnetic field with an excited line 2. A coil 81 of a keyboard 8 is connected to a power supply circuit 83 by a switching circuit 82. The power supply circuit 83 rectifies the guide signal of the coil 81 and stores it in a capacitor 84. When enough energy is stored, the power supply circuit 83 applies energy to another circuit, and the switching circuit 82 connects the coil 81 to a second exciting circuit 85. The second exciting circuit 85 generates an exciting signal and applies it to the coil 81 while receiving modulation due to a key code from a key code generating circuit 87. Since the coil 81 generates the AC magnetic field, the guide signal is induced in a detecting line 3. The guide signal is guided to a signal processing circuit 5 and a demodulation circuit 6, and the key code is restored.

Title: Two-layer molding
Inventor: MIYAOKA TERUO
IPC: C08L53/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To enable an engineering plastic to be thermally fusion-bonded tightly with an elastomer by coating an elastomer layer composed of a mixture of a specific styrene block copolymer and polystyrene and polypropylene on an engineering plastic layer. SOLUTION: A styrene.ethylene.propylene.styrene block copolymer (SPS) is selected as an elastomer layer to be coated on an engineering plastic layer, and polystyrene (PS) is added in order to further improve the thermal fusion- bonding properties of (SEPS). The content of PS to be added is 10-50 pts.wt. for 100 pts.wt. of SEPS. Addition of the PS to the SEPS causes the increase of hardness, so that polypropylene (PP) needs to be added to adjust the hardness. The content of PP to be added for adjusting the hardness is routinely 10-50 pts.wt. for 100 pts.wt. of SEPS. Further, to prevent the thermal fusion-bonding properties from becoming deteriorated on account of the addition of PP, it is preferably to add thermoplastic polyurethane.
