Title: Reduction method of intrinsic polar shift at inside of optical grating
Inventor: KORADOO DORAGON
IPC: G02B6/10
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce an inherent polarity shift caused by birefringence between a TE mode and a TM mode of an optical signal by containing a step to irradiate plural waveguides of an optical grating in different irradiating time. SOLUTION: Irradiating beams are irradiated over the whole waveguides at scanning speed different with every waveguide. The beams are scanned in the (y) direction, and a lens condenses the irradiating beams, and a (y) directional beam width Wy becomes narrower than an (x) directional beam width Wx . In the principle, the beam width Wy is sufficiently small, and only a single waveguide and its pole vicinity area can be independently irradiated from an adjacent waveguide (separately from an adjacent waveguide). A light beam simultaneously irradiates plural adjacent waveguides constituting only a part of the whole number of waveguides in an optical grating. The waveguides are bent, and an effective length to irradiate the waveguides is different with every waveguide, and a correction factor is introduced to scanning time, and a central part and a bending part of the waveguides are irradiated.

Title: Still reproduction of vtr and double-speed reproduction control unit
Inventor: KOJIMA NOBORU
IPC: H04N5/783
Filed: 1979-03-20
Abstract: PURPOSE:To increase the main track reproduction output as well as compensate the horizontal synchronous shift at that moment by selecting the proper tracking mode according to the still or double-speed reproduction, thus preventing occurrence of the skew. CONSTITUTION:The signals reproduced through heads 19 and 20 are supplied to head change- over switch 23 through preamplifiers 21 and 22. Switch 23 supplies the reproduction output to signal process circuit 24 via the control pulse of 30Hz switch signal 8 and in synchronization with the reproduction period of each head. The reproduction signal passed through circuit 24 is supplied to H/2-shift compensation circuit 27 consisting of H/2-shift compensation circuit 25 and frame change-over switch 26 to receive the skew compensation. In other words, the reproduction signals are switched before and after delay line 25 and with the timing of the control pulse of 15Hz, and thus the H-shift features the integer-fold of H at the switching time to the reproduction by head 20 from the reproduction by head 19 and with every frame. Thus the reproduction signal is delivered through terminal 28 as the signal received the skew compensation. For the double- speed compensation, the H-shift compensation is given at the switching time of reproduction from head 20 to head 19.

Title: Armature conductor for gap winding type rotary machine
Inventor: WATANABE MASATOSHI
IPC: H02K3/14
Filed: 1978-03-24
Abstract: PURPOSE: To reduce the generation of eddy current and impt improve the mechanical strength of a conductor by Robel-dislocating a number of flat angle strands to form a strand bundle and combining and Robel-dislocating a number of these strand bundles to an armature conductor.  
     CONSTITUTION: For example, the flat angle strand 7 is combined two wide and eight high in the width direction w and Robel-dislocated to form a strand bundle 9. For instance, these strand bundles 9 are also combined two long and eight wide in the height direction and Robel-dislocated to form an armature conductor 3. The dislocation pitch of both strands 7 becomes larger than that of both the strand bundles 9 so that the pitch of each Robel dislocation cannot damage strand insulation. This reduces the crossover surface against the magnetic flux of the flat angle strand 7 and enables doubled dislocation. Consequently, the generation of eddy current is reduced and both the strands 7 are surface-contacted to improve mechanical strength.
