Title: Controller for ac elevator
Inventor: ISHIDA MINORU
IPC: H02P27/06
Filed: 1986-07-02
Abstract: PURPOSE:To ensure a drive power supply for an AC elevator even at a new building construction site, to which a three-phase AC power supply is not provided, by supplying a three-phase induction motor with power through a single- phase full-wave rectifier circuit and a three-phase full-wave control bridge. CONSTITUTION:A single-phase full-wave rectifier circuit 1 is connected at output terminals R, S for a single-phase AC power supply as a power supply for welding, etc. at a new building site before a three-phase power supply is mounted. A three-phase full-wave control bridge 2 converts DCs outputted from the single- phase full-wave rectifier circuit 1 into three phase ACS. The three-phase AC output is fed to power input terminals U, V, W for a three-phase induction motor and changed into load currents Iu, Iv, Iw, thus driving an AC elevator.

Title: Rotary head type magnetic recording and reproducing device
Inventor: NAKATSUKA AKIHITO
IPC: G11B5/02
Filed: 1986-07-02
Abstract: PURPOSE:To perform high-gain amplification in a wide band by connecting one ends of N-number of windings to ground sides of N-number of inverting and non-inverting amplifiers and connecting the other ends of windings to input sides of amplifies and combining ground ends of windings and amplifiers so that all output signals of windings are added. CONSTITUTION:Two windings are wound in the same channel by one turn with respect to windings on the side of a stator 18, and output signals have polarities opposite to each other and have the same amplitude because ends of windings whose winding directions are opposite to each other are earth ends. Since the number of turns of windings of the stator 18 is a half of two turns in the forward direction and the reverse direction, the inductance component of windings of the stator 18 is reduced (1/2)<2> times, and therefore, the resonance frequency of output signals amplified by a differential amplifier 19 appears in a high frequency band. Thus, the resonance frequency of a reproduced signal is raised and a wide band signal is amplified with a high gain.

Title: Anti-pitting corrosion aluminium alloy
Inventor: TAKEUCHI ISAO
IPC: C22C21/10
Filed: 1977-12-26
Abstract: PURPOSE: To provide an aluminium alloy with an excellent anti-pitting corrosion with addition of a specified amount of Zn to metal aluminium.  
     CONSTITUTION: 0.1 to 0.7% of Zn is added to metal aluminium with a purity of 99 to 99.99%% to produce a anti-pitting corrosion aluminium alloy. The addition of Zn lessens the strength of anti-pitting corrosion oxidized film formed on the surface of aluminium. As a result, it is converted to a total corrosion type in the corrosion form. Thus, local corrosion and pitting can be inhibited.

Title: Multibeam optical head
Inventor: ITO MASATAKA
IPC: G11B7/1359
Filed: 1986-07-02
Abstract: PURPOSE:To perform optical space separation with a small stroke by making one of plural beams incident at an angle smaller than the critical angle not to totally reflect this beam and allowing a part of this beam to pass through a prism and making the other beams incident at angles larger than the critical angle to totally reflect them and completely separating the beam transmitted through the prism form the other beams. CONSTITUTION:Since light emission points of plural LDs 21a-21c are not placed on the same optical axis of a lens, optical axes of beams transmitted through a collimator lens are not parallel with one another. Beams deflected at 90 deg. by a polarizing beam splitter 23 are made incident on a first reflecting face 11 of a prism 50 and are transmitted through this face 11 without being much lost and are made incident on a second reflecting face 12. The reflecting face 12 is so set that the angle of incidence of a beam 20f for servo is smaller than the critical angle but angles of incidence of the other beams 20d and 20e are larger than the critical angle, and consequently, the beam 20f is not totally reflected and is separated into a transmitted light and a reflected light. Since only the beam 20f is transmitted through the reflecting face 12, the beam 20f for servo is detected with a small crosstalk independently of the other beams.
