Title: Method and apparatus for producing thin organic functional material film
Inventor: KATO MASAKAZU
IPC: C23C14/12
Filed: 1987-06-08
Abstract: PURPOSE:To form a film of an org. functional material at a uniform thickness on a base material surface at a low cost by bringing the vapor of the org. functional material together with a carrier gas into contact with the surface of the base material for film formation so that said vapor is deposited by evaporation on said surface in a low vacuum vessel. CONSTITUTION:A valve 10 of a cylindrical 1 for the carrier gas such as He or Ar connected to the vacuum vessel 4 and a main valve 11 in the vessel 4 are closed and a valve 12 of a bypass 13 is opened, then the inside of the vessel 4 is evacuated to a vacuum by a vacuum pump 7. The phthalocyanine-based org. functional material on a boat 3 is heated and evaporated by a heating means 2 and the initial gaseous impurity-contg. vapor is discharged. The valves 10, 11 are then opened and the valve 12 is closed to supply the carrier gas such as He into the vessel 4 where the vapor of the material 9 is passed together with the carrier gas on the surface of the cylindrical body 5 under a relatively low vacuum degree of 10<3>-10Torr to easily deposit the thin film of phthalocyanine-based org. functional material by evaporation on the surface of the base body 5 to a uniform thickness. The vapor of the org. functional material which is not used for the vapor deposition is captured by a cold trap 6 and is thereby prevented from entering the pump 7.

Title: Disk player
Inventor: SAGAWA YOSHIHIRO
IPC: G11B25/04
Filed: 1994-06-23
Abstract: PURPOSE:To reduce the number of driving motors by reversely rotating a spindle motor and pinching/releasing the disk. CONSTITUTION:A spindle motor 16 is reversely rotated to transmit a rotating force to spur gears 44, 47 and to hold the disk 3 on the turntable 5. Due to large rotational resistance of the gear 47, its repulsion works so that a fluctuating plate 45 causes the gear 47 to be engaged with the spur gear section 32b of the cam 32. Then the rotational force of the motor 16 rotates the cam 32 in the direction of the arrow. When the cam 32 rotates, the position where a tapered bar protrusion 32a of the cam 32 is engaged with a working piece 34 is shifted to a low position so that an auxiliary chassis 14 moves and pushes the turntable 5 to the position where the disk 3 is pinched and held. This condition is detected by a switch and, in response to the detection signal, the reverse rotation of the motor 16 stops. By this method, the rotational force is transmitted to the holding mechanism of the disk to pinch and/or release the disk and thereby reduce the number of driving motors.

Title: Pulse laser distance measuring apparatus
Inventor: OKAMOTO YUJI
IPC: G01S17/10
Filed: 1991-06-14
Abstract: PURPOSE:To detect the rise of a pulse as near to the center of pulses as possible so as to prevent errors in measuring distances by transmitting as transmitted laser beam a plurality of laser pulses whose levels are varied stepwise, and receiving the laser pulses reflected, and selecting that pulse whose peak value of laser beam intensity is higher than the threshold of a receiving system but does not reach a saturation value, so as to measure distances. CONSTITUTION:A control and arithmetic portion 1 triggers a laser driver 2 and then pulses are successively emitted from a transmitting portion 3. The transmitted pulse beam 301 reaching a target is received at a receiving portion 4 as pulse beam 401 consisting of received pulses 9-11 and is amplified 5 and subjected to control and arithmetic 1. Then scanning is performed in the reverse direction from the pulse 11 to the pulse 9 and the time T2 counted by the pulse 10 recognized as the first one is adopted. In this case, the pulse 11 is not recognized because its intensity is lower than a threshold 13, and the pulse 10 is the first to be recognized. The time T2 is closer to time T corresponding to the actual distance than to the time T1 for recognition; i.e., the pulse 9 exceeds a saturation level 12 and errors are included also in the time T1.
