Title: Magnetic recording medium
Inventor: AOKI NOBUYUKI
IPC: C09D5/23
Filed: 1990-06-11
Abstract: PURPOSE:To obtain a coating film having anisotropic orientation with good orientation by constituting the magnetic layer with a coating type magnetic recording medium so that the layer has the axis of easy magnetization in a specified angle range to a base plane. CONSTITUTION:When the magnetic coating material to form a magnetic recording layer is applied with high shearing stress, the axis of easy magnetization of planar magnetic fine particles (in the thickness direction of the planar fine particles) in the coating material is oriented by the shearing stress to some extent to the base plate. Before the coating film is dried and solidified, a magnetic field is applied in the range from 45 to 90 degree so that the magnetic powder is magnetized in the direction from 45 to 90 degree to the plane. Thereby, the magnetic recording layer having good orientation can be formed.

Title: Focal plane shutter
Inventor: FUJITA SUSUMU
IPC: G03B9/36
Filed: 1979-11-26
Abstract: PURPOSE: To simplify the mechanism and make it possible to incorporate it in the pocket-size camera, by causing the charge plate to ascend and descend through the gear system by the reversible motor to open and close the shutter charge and the mirror.  
     CONSTITUTION: The focal plane shutter is constituted by charge lever 8, release lever 9, the front curtain stop lever which stops pin 13, which is protruded at the lower end of front curtain material 4 of the reversible motor which drives gear row GT, to initial set 1, and so on. In this constitution, when the shutter button is depressed, the stop of release lever 9 is released, and release lever 9 releases the stop of front curtain material 4 due to elasticity. As the result, front curtain material 4 ascends due to elasticity of charged spring 23 until pin 13 in the lower part is stopped by arm 8a, and exposure aperture part 5 is caused to agree with exposure aperture part 7 of rear curtain material 6 to expose film (f).

IPC: H04L69/40
Filed: 1981-09-28
Abstract: PURPOSE:To simplify the circuit constitution and to save the number of components, by providing an exclusive OR circuit, in a local circuit accommodating two-wire line. CONSTITUTION:A local device 101 and an opposing station device 102 having a 2-wire interface circuit are connected via a line 103.

Thus, when the signal at the terminal 1 is a logical ''1'' or ''0'', the output of the circuit 14 is logical ''0''. As a result, the transmission signal does not give interference to the reception signal.

Title: Polyester fiber winding method
Inventor: OKA KENICHIROU
IPC: B65H54/02
Filed: 1983-08-25
Abstract: PURPOSE:To prevent aging making a package under winding out of contact by means of a spindle drive winder then winding with specific slow traverse and higher than specific speed thereby reducing distortion caused by the winding position of package. CONSTITUTION:The winding speed must be higher than 5,000m/min where 5,500m/min is preferable, to produce a string having such inner structure as the crystal orientation fc >=0.85 and the non-crystal orientation fa <=0.5, and since inter-molecular bonding at the crystal portion is strong, the spinned thread can be used practically. In order to prevent distortion under winding, a spindle drive type winder is employed to wind the package under completely contactless state. Then the winding width is reduced gradually as the thread diameter of package increases, and it is wound with slow traverse satisfying the following relation V/2,400<=T<=V/180 assuming the winding speed is V(m/min) and the traverse speed is T(cm/sec). Consequently, the turning shock is reduced to eliminate distortion when winding.
