Title: Disk player
Inventor: YOKOTA TOMIYUKI
IPC: G11B17/34
Filed: 1985-03-08
Abstract: PURPOSE:To enable smooth rotation and make a turntable unnecessary by sending air to the lower face of a disk and floating the outer peripheral part of the disk. CONSTITUTION:When a motor 11 becomes the state of rotation, air is sent to the lower face of a disk 3 by a blowing fan 7 attached to the back of a flange 4. The air passes through radial guide grooves on the upper face of a chassis 10 and passes between a group guard receiving rib 8 and a disk group guard 9. Consequently, when the disk rotates, the outer peripheral part of the disk floats up and not in contact with the rib 8. Thus, friction is eliminated and smooth state of rotation is obtained.

Title: Laser radar
Inventor: SUZUKI TAKAYUKI
IPC: H01S3/00
Filed: 1995-03-07
Abstract: PURPOSE: To obtain a laser radar whose search accuracy can be enhanced by comprising a specific irradiation optical system and an irradiation timing setter which makes an irradiation angle nearly equal. CONSTITUTION: An irradiation timing setter 22 makes the light-emitting time interval of a laser diode 15 nonlinearly variable in such a way that the counting desired value of a self-propelled counter built in a timer circuit 18 is changed whenever the circuit 18 issues trigger pulses. The difference between adjacent counting desired values is set as large as the laser diode is brought close to a scan starting point of a scan finish point. The difference is set as small as the laser diode is brought close to the scan central point. As a result, in the whole region of a scan range, the change width of an irradiation angle for every laser beam is kept always at a constant-value pitch, and a scan density can be made uniform.  In addition, without modifying an irradiation optical system, it is possible to deal with the irradiation angle by correcting the irradiation timing of the laser beam, an irradiation optical system in conventional cases can be used as it is, and a very economical apparatus can be constituted.

Filed: 1985-03-11
Abstract: PURPOSE:To make recording and reproducing of simultaneous erasing and recording type by one pickup and to monitor at the time of recording by using beams of different wavelength at the time of recording and reproducing. CONSTITUTION:When recording, a polarized light beam Bm having an oscillation plane perpendicular to the face of paper is oscillated from a light source 1. The beam is reflected by the first beam splitter 3 and projected vertically onto a recording medium S. On the other hand, a beam Bm oscillated from a light source 2 is a polarized light beam B having an oscillation plane parallel to the face of paper and intensity of the sub-beam Bm is modulated according to binary coded information to be recorded by controlling the light source 2. When reproducing, the main beam Bw is oscillated lowering its intensity than the case of recording, and reflected light from the medium S is utilized as controlling light as in the case of recording. The sub-beam Bm is oscillated at a fixed intensity without making intensity modulation, and reflected light from the medium S is received by the second photoelectric converting device similar to the case of monitoring of recording, and converted to electrical signals.

Filed: 1979-04-19
Abstract: PURPOSE: To prevent drop of secondary voltage and to improve reliability by connecting transistors for compensating temperature in series to a capacitor in parallel with the resistance connected between the base and emitter of a control transistor.  
     CONSTITUTION: After high temperature has achieved, when trigger voltage of a control transistor 8 is dropped, also trigger voltage of a transistor 12 is dropped. In response thereto, internal resistance between the emitter and collector of the transistor 12 is dropped, which increases charging current of a capacitor 11. Thus, when coming up to high temperature, with increase of equivalent resistance of external resistance connected between the base and emitter of the control transistor 8, premature trigger of the transistor 8 is prevented, in spite of changes in the temperature, the control transistor 8 is triggered at almost constant voltage.
