Title: Ac 2-wire proximity switch
Inventor: INABA TSUNEO
IPC: H03K17/95
Filed: 1985-07-03
Abstract: PURPOSE:To make a leakage current at off-state to a very small value and to lower the residual voltage by using a different path for a drive power fed to a proximity detecting circuit depending on/off state of the proximity detecting circuit. CONSTITUTION:When the detection circuit 2 is turned on, a power supply from a rectifier bridge 3 is fed to the detection circuit 2 through the path of a light emitting diode LED, a resistor R3, a transistor (TR) 2, a TR 3 and a diode D2 not via a DC stabilizing circuit 6. When the detection circuit 2 is turned off, a power supply from the rectifier bridge 3 is regulated by the DC stabilizing circuit 6 and fed to the detection circuit 2 via a resistor 4 and a diode D1 to decrease the current consumption. In this case, even when the value of the resistor 4 is selected sufficiently large to decrease the leakage current, or the conduction angle of a thyristor SCR is increased, the drive current to the detection circuit 2 is ensured sufficiently.

Title: Method for embedding metal into surface via hole
Inventor: IZUMI TAKAYUKI
IPC: H01L21/288
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To use the flat surface of a substrate itself as a conduction layer for eliminating nonuniformity of a conduction layer by forming a semi-insulation layer on a low-resistance substrate, then forming a via hole, and performing electrolytic plating of the low-resistance substrate as the conduction layer and hence embedding metal into the via hole. SOLUTION: A semi-insulation layer 2 is formed on a low-resistance substrate 1, and further epitaxial structure 3 is formed as needed for creating a substrate A. Then, an ohmic contact 4, an interlayer insulation film 5, wiring 6, and an insulation film 7 are formed on the substrate A. Then, a via hole 8 is formed. In this case, the via hole 8 is stopped in the middle of the low-resistance substrate 1. Then, by electrolytic plating with the low-resistance substrate 1 as a conduction layer, embedded metal 13 is formed in the via hole 8, thus making uniform the conduction layer, since the flat surface of the substrate itself is used as the conduction layer without forming the conduction layer on a surface with large recessed and projecting parts which are generated by sputtering or the like as in conventional methods.

Title: Orthodontic appliance
Inventor: YAMAUCHI KIYOSHI
IPC: C22C5/04
Filed: 1990-06-04
Abstract: PURPOSE:To enable the manufacture of an orthodontic appliance which enables absorption and releasing of reversible energy in loading of deformation or removal thereof and with little toxicity to a living body, by replacing a part of a TiPd alloy or Pd with one or a combination of Fe, Cu and W. CONSTITUTION:This orthodontic appliance is obtained by replacing a part of a TiPd alloy containing Pd 45.0-51.0at% and Ti as remainder with at least one element selected from a group of Fe, Cu and W at a rate of upto 30at%. This has little toxicity to a living body. This also allows adsorption and releasing of reversible energy in loading of deformation or removal thereof at least at an internal temperature of an oral cavity. The reason why the content of Pd in the base TiPd alloy is set to 45-51at% is because an action area as shape memory alloy is allowed within this range. The total amount of the element to be replaced is set under 30at% because the action as shape memory reduces when 30at% is exceeded.

Ru, Sc, Y, Zn, Ti, etc., is formed on the film 4 and a Co-base alloy thin film is formed. Consequently, the Co-base alloy film consisting of columnar crystals having well-controlled and uniform grain diameter can be formed. The thicknesses of the first crystal grain-controlled film 4 and the second crystal grain-controlled film 2 are regulated to 100-3,000Angstrom  and the thickness of the film consisting of columnar crystals having controlled grain diameter is controlled to 150-3,000Angstrom . Consequently, the degree of orientation of the C axis of the magnetic thin film is ameliorated and the magnetic characteristics are improved.

Title: Electronic watch
Inventor: SHIDA MASAHARU
IPC: G04C3/14
Filed: 1977-12-02
Abstract: PURPOSE:To reduce the electric power by stepwise shortening and enlarging the width of the normal drive pulses of a step motor so that the normal drive pulses of the minimum width according to the load applied may be supplied to the step motor. CONSTITUTION:The output P0 of a waveform composing circuit is used to determine the minimum width of normal drive pulses and is preset at about 1.9 m sec. When it is detected that a rotor has failed to be turned by the output signals T4 from a detecting circuit, signals P2 are generated so that auxiliary drive pulses having a width of 7.8 m sec for ensuring the maximum torque are fed to a motor. In response to signals P3, the drive pulses are then turned at the second second into drive pulses of width of 2.4 m sec. If these pulses also fail to drive, the auxiliary drive pulses P2 are fed, and the normal drive pulses take a width of 2.9 m sec at the third second. If this pulse width also fails to effect the rotations, the same operations are repeated so that the rotor may be driven at such pulse width as is close to the rotatable limit.
