Title: Automatic operation system of projector
Inventor: NAKAYAMA ICHIROU
IPC: G03B21/00
Filed: 1979-02-26
Abstract: PURPOSE: To operate all operations fully automatically by deciding the travel condition of film with the detection signals of the two film sensors disposed on the way of traveling of the film as reference signals through the use of a microcomputer and performing the operation up to the stoppage of the projector at the ending of projection.  
     CONSTITUTION: If loading state is set when the ten thousandth place of the counter is F (1111 in binary notation) and it becomes projection end → automatic stop when not F, and when it is decided in the step 32a that the ten thousandth place of the counter is not F, it assumes the ending of projection, then the display of the counter is reset to F by the step 33 and the projector is automatically stopped by the step 34. The resetting of the counter and the automatic stopping are accomplished by the commands of the microcomputer. On the other hand, when it is decided by the step 32a that the ten thousandth place of the counter is F, the digits below the ten thousandth place of the counter are made all 0000 by the step 35 and at the same time they are cleared when the film passes the film sensors.

Title: Displacement enlargement mechanism
Inventor: OSHIMI AKIRA
IPC: H01L41/09
Filed: 1992-02-06
Abstract: PURPOSE:To protect the other piezoelectric element against breakdown by additionally disposing a displacement regulating section between two piezoelectric elements and setting the stiffness at the displacement regulating section such that an angular displacement takes place at a displacement part, with hinges at the opposite ends of the other piezoelectric element as fulcrums, when a voltage is applied only on one piezoelectric element. CONSTITUTION:A rod type displacement regulating section 4 is disposed between piezoelectric elements 2, 3 while being secured through hinge sections 4a, 4b at the opposite ends to the surface 1a of a displacement part 1 and the surface 5a of a fixed part 5. The piezoelectric element 3 elongates upon application of voltage but the piezoelectric element 2 does not elongate because no voltage is applied thereon. Consequently, an angular displacement takes place between the surface 1a of the displacement part 1 and the surface 5a of the fixed part 5. Since stiffness at the displacement regulating section 4 is set in such a way that an angular displacement takes place between the surfaces 1a, 5a with hinges 6a, 6b secured to the piezoelectric element 2 as fulcrums, tensile force is not applied on the piezoelectric element 2 which is thereby protected against breakdown.

Title: Thermal write recording system
Inventor: UEDA HIROYUKI
IPC: G11B7/24
Filed: 1988-02-01
Abstract: PURPOSE:To improve the C/N characteristic of the thermal write recording system to raise the recording density by using the fact that the direction of orientation is different by the cooling speed at which smectic liquid crystal is changed from the heated isotropic liquid phase state to a prescribed phase. CONSTITUTION:A high polymer film consisting of a polyimide or the like is formed on a substrate and Ti and O2 are used as the target material and introduced gas respectively to perform oblique sputtering, thereby forming a liquid crystal cell. Liquid crystal CS-1015 is injected to this cell and is slowly cooled from the isotropic liquid phase state to the smectic A phase and is oriented in the direction of sputtering. When the laser light is projected to this liquid crystal, the irradiated part is quickly heated to the isotropic liquid phase and is quickly cooled to the smectic A phase again but the direction of orientation is perpendicular to that before projection of the laser light. These two states are used to read out the recording state of liquid crystal having the guest host effect with a high C/N.
