Abstract: PURPOSE:To form an electron emitting element capable of controlling the emitting electron amount by the light and to enable the integration in a simple structure, by superposing a connection-type photoelectric converting domain and an MIM type electron emitting element domain. CONSTITUTION:A connection-type photoelectric converting domain is formed by superposing an N-type semiconductor domain 3, a P-type semiconductor domain 4, and a conductive domain 5, partially over a transparent electrode 2 of a light-permeable base plate 1. At both sides of an insulating domain 6, the domain 5 and a metallic layer 7 are positioned, and an MIM type electron emitting element domain is formed to emit electrons by applying a necessary voltage between the layer 7 and the domain 5, emitting from a recess 9 with a work function reducing material domain 8 at the surface of the layer 7. The electrons generated by the light permeated through the plate 1 are implanted to the domain 5, and the electron amount emitted from the recess 9 is controlled. Since the domain 5 is the common part for the two domains, the structure is simple, and since it is a superposed structure, the integration work is easy.

Title: Control system of motor maintenance torque
Inventor: KONO TOSHIYUKI
IPC: H02P21/22
Filed: 1989-11-02
Abstract: PURPOSE:To obtain a thin maintenance torque generating mechanism by forming a rotor fitted with permanent magnets into a thin disc maintenance torque- generating structure provided with teeth. CONSTITUTION:The title apparatus is composed of a ring 2 having magnetic projecting teeth 1 in the same number of pole pairs as that of a motor and permanent magnets 3 in the same number as that of the projecting teeth, which magnets are arranged in the manner of causing projecting teeth 1 fitted to a rotor 4 to face the ring 2. When DC current is applied to a motor command current to operate a motor at the time of rotation of the motor, cogging by a torque generated in a maintenance torque-generating part is canceled in the motor and a normal output is taken out. On the other hand, when a stop time, etc., are supposed, both motor current and DC current are zero and only the maintenance torque works and a motor output shaft is fixed by the maintenance torque. Therefore, when a command power supply is cut OFF while the motor is operated, the rotor is maintained to stop at an arbitrary place finally by the maintenance torque.

Title: Optical recording medium and optical storage device
Inventor: FUJI HIROSHI
IPC: G11B7/24067
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent destruction of information and to enhance reliability by providing a slider, which is loaded with a probe for recording or reproducing information, with a projection so that the slider can avoid colliding with an area for recording or reproducing information. SOLUTION: Plural information tracks t1-t7 are arranged on the recess 5h of a disk 5 and are protected by a projection 5f. An optical probe 7a is movably controlled in the x and y directions with an actuator 8. With dust or the like entering a gap between a probe slider 9 and a disk 5, causing collision, the projection 5f prevents the bottom of the probe slider 9 from coming into contact with the area of the information tracks t1-t7, protecting data from being destructed by the collision. A substrate 5d is formed so that a difference in level between the recess 5h and the projection 5f is not more than a distance which evanescent light reaches, i.e., about a few ten nm's, thereby enabling information recording/reproduction on the recess 5h by using the evanescent light.
