Title: Optical recorder
Inventor: DEGUCHI TOSHIHISA
IPC: G11B7/09
Filed: 1993-07-29
Abstract: PURPOSE:To improve the characteristic of the device by arranging a photodetection means detecting part of a laser beam while being tilted with respect to an optical axis so as to eliminate the effect of a stray light generated in an optical system. CONSTITUTION:A polarized light beam splitter 5 leads part of a laser radiating light to photodetectors 6, 11, 12, 17. The detector 6 receives part of a laser beam reflected in the splitter 5 and is arranged with a tilt with respect to the optical path so that a reflected light from the surface of a light receiving element is not a stray light. When a stray light from a magnetic recording medium 1 is in existence on the detector 17, a servo error signal, that is, a focus error signal and a track error signal receive its effect. Since the effect due to the stray light caused in the optical system is eliminated from the error signal, a deviation from a servo object value caused by a difference from the reflectance of the medium 1 or a difference from laser radiation luminous quantities is avoided and the optical head is stably controlled. Thus, the optical head coping with recording media having various optical characteristics is obtained.

Title: Molding structure for automobile
Inventor: TSUCHIYA MASANORI
IPC: B60R13/04
Filed: 1982-10-27
Abstract: PURPOSE:To reduce the weight and the cost of adhesive tape and to improve the ornamental design function by forming a body with hard foam plastic and covering it with a top skin having ornamental treatment. CONSTITUTION:The body 13 of a molding 11 is formed with hard foam plastic such as hard foam vinyl chloride etc., and is covered with a top skin 12 having ornamental treatment such as stripe pattern 14.

Title: Optical scanning device
Inventor: INAISHI KOUJI
IPC: G02B26/10
Filed: 1990-07-17
Abstract: PURPOSE:To facilitate the assembly and installation and to scan a light signal accurately regardless of a shock by performing control so that the blinking of a light source is synchronized with the operation 5 of a shutter part and an optical scan is made by one line. CONSTITUTION:When a control part 7 blinks the light source part 1 with a received signal to send a light signal, the light signal is made incident directly to reach a light projection end through an optical waveguide plate 2, and a photosensitive drum 6 is exposed through the opening part 3 of a shutter 4. The shutter 4 is in reciprocal motion along the light projection end of the optical waveguide plate 2, so the opening part 3 of the shutter 4 moves from one end to the other of the light signal projection end of the optical waveguide plate 2. Therefore, the light signal needs neither to be a light beam not rotated, and the one-line scan of the photosensitive drum 6 is made. Consequently, the installation and assembly in a device are facilitated and the light signal can accurately be scanned regardless of a shock, etc.

Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a ball point pen tip which is optimal for a double color- developing ball point pen by setting a difference between a ball diameter and a ball house inner diameter for the ball point pen tip at a specified dimension or higher. SOLUTION: This ball point pen tip is constituted of a ball 1, a ball house 2 and an ink passage 3, and a difference between the ball diameter and the ball house inner diameter (i.e., the total of 4+4) is ensured to be 0.03 mm or higher, preferably in a range of 0.03-0.04 mm. The difference is determined mainly by the ball diameter, the ball house inner diameter and the ball house shape, and by adjusting either one of them, the difference can be properly set. Also, on the distal end edge 5 of the ball house, a caulking treatment is applied in order to prevent the ball from dropping out. Since a sufficient ink flow-out amount can be ensured, an excellent double color-developing effect can be obtained.

Title: Codeless telephone system, its master set and its slave set
Inventor: NEGISHI HIDEKI
IPC: H04W48/12
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent control signals of adjacent master sets arranged for every service area from being overlapped and to enable a slave set at each service area to accurately receive the control signal by using a slot part dividing a frequency for a control channel with a specified time and transmitting change control signal for the slot from the master set. SOLUTION: The master set uses a control signal for incoming call information which is intermittently transmitted to a waiting slave set by a specified time slot and periodically confirms whether a calling is enabled or not. When an 'enable calling signal' from the slave set showing normal reception cannot be received, there is the possibility of radio wave interference. In this case, the master set changes a time slot transmitting the control signal. Thus, by changing the time slot, the radio wave interference can be eliminated and the slave set disabled to call removes the control signal by a 'master set retrieval' and can recover enable calling state.
