Title: Solenoid apparatus
Inventor: TAKAHASHI IKUO
IPC: H01F7/16
Filed: 1985-07-04
Abstract: PURPOSE:To increase the shock resistance of a movable iron core and to reduce the effect of a diamagnetic field by applying pulse D.C. voltage which magnetizes a fixed iron core enabling reversal of positive or negative polarity, by providing an electromagnetic coil for reciprocating a movable iron core and by covering the movable iron core with a protection tube. CONSTITUTION:When an electromagnetic coil 10 is magnetized by applying positive magnetic field pulse D.C. voltage, a positive magnetic field is generated in a fixed iron core 11 and a movable iron core 12 is attracted to the fixed iron core 11. In this state, if diamagnetic D.C. voltage is applied to the electromagnetic coil 10, a diamagnetic field is generated in the fixed iron core 11, the movable iron core 12 is returned by repulsion and is reciprocated by the inversion of the magnetism of the D.C. voltage applied to the electromagnetic coil 10. Since the movable iron core 12 is protected by a protection tube 13, the movable iron core 12 made of a permanent magnet which has low shock resistance is neither cracked nor broken off.

Title: Projection type display device
Inventor: SEKINE ATSUSHI
IPC: G09F9/00
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To illuminate each light valve with the same luminance and to obtain a bright full-color projected image free from irregularities in the image by making the length of an optical path between a light source and a light valve for a luminance signal equal to the length of an optical path between the light source and a light valve for a color signal. SOLUTION: Light source light emitted from the light source 1 in a direction +X is made incident on a polarized beam splitter(PBS) 2. In the PBS 2, the light source light is separated by a polarizing/separating part so as to become P-polarized light which is transmitted through the PBS 2 and emitted in the direction +X and S-polarized light which is reflected by the PBS 2 in a direction +Y, then, both of P-polarized light and S-polarized light are emitted from the PBS 2 in directions orthogonal to each other. The P polarized light emitted by the PBS 2 in the direction +X goes toward a direction +Z through a mirror 3, then, the light is made incident on the light valve for a color signal 5, thereafter, the light is made incident on a projecting lens 7.  The S polarized light reflected by the PBS toward the direction +Y goes toward a direction +Z through the mirror 4, then, the light is made incident on the light valve for a luminance signal 6, thereafter, the light is made incident on a projecting lens 8. That is, by such a constitution, the length of the optical path between the light source 1 and the light valve 5 is made equal to the length of the optical path between the light source 1 and the light valve 6.

Title: Paste type nickel positive electrode
Inventor: ISAWA KOJI
IPC: H01M4/62
Filed: 1986-06-25
Abstract: PURPOSE:To obtain high utilization and good high rate discharge performance by mixing nickel fibers in paste-like active material. CONSTITUTION:Nickel fibers produced by chatter vibration cutting method are formed in a nonwoven fabric, then sintered in a reducing atmosphere to form an electrode substrate. A paste like active material mainly comprising nickel hydroxide is supported in the substrate to obtain a paste type nickel positive electrode. Short nickel fibers obtained by cutting nickel fibers produced by a cold wire drawing method or a focusing wire drawing method in a specified length are added to the paste-like active material. Thereby, short nickel fibers functions as conductive passages between the active material and the substrate, and active material utilization in low rate discharge is increased and decrease in discharge capacity in high rate discharge is retarded.
