Title: Optical disk device
Inventor: SASAKI TAKESHI
IPC: G11B7/085
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain lens position detecting sensitivity based on a normal reference value by measuring and setting an operation reference value of the sensitivity whenever the device is started up in case of fluctuation in the lens position detecting sensitivity. SOLUTION: Position detecting sensitivity of a 1st lens, valuated by calculation is made by an arithmetic and control circuit 35 as a parameter to be used for a VC motor during its position control arithmetic time. Then, a 1st lens actuator driving command signal for making a 1st laser beam B1 jump continuously over ten tracks in the inner circumferential direction of a medium is outputted to a 1st D/A converter 361 , and then a changeover is made to the VC motor position control state by a 1st position signal PS1 , and position sensitivity detecting operation is returned to its beginning, so as to complete a series of automatic correcting operation of lens position detecting sensitivity.  Thus, by specifying the lens position detecting sensitivity in measurement and calculation prior to the correction, a control loop gain for the VC motor is not varied, and hence stable tracking control is obtained.

Filed: 1994-11-29
Abstract: PURPOSE: To obtain a solid-state image pickup element and its drive method reading charges of all pixels without charging the order of them regardless of provision of two vertical transfer register electrodes per one photodiode. CONSTITUTION: Two electrodes of vertical transfer registers (VCCD) 3 are provided for one photodiode(PD) 4; the charges in odd number lines of PDs 4 are transferred to the VCCDs 3, received by a storage area 2; and the period of the transfer clock for VCCDs 8 in the storage area 23 is selected half a period T0 of the transfer clock for the VCCDs 3 in an image pickup area 1 (That is, the drive frequency is doubled). Thus, a charged packet and an idle packet are alternately transferred in the storage area 2 and the charged packet of an odd number line is saved and stored in a temporary save CCD 9. Similarly since the charged packets of an even number line with an idle packet in between are transferred similarly in the VCCD 8, after the charged packet of an odd number line read from the temporary save CCD 9 is moved to the position of the idle packet, the resulting charged packets are transferred to a horizontal transfer register (HCCD) 5.

Filed: 1988-11-22
Abstract: PURPOSE:To prevent sensitivity from decreasing by forming the aluminum particles of a thin aluminum film for forming a light shielding film smaller than those of a thin aluminum film formed as signal wirings in a solid state image sensor. CONSTITUTION:An N-type diffused layer 2 is formed on one main face of a P-type silicon substrate 1, a reading electrode 3 of polycrystalline silicon is formed through an oxide film, an interlayer film 4 is then formed, covered with a thin aluminum film thereon, and formed in a pattern to form a light shielding film 5. Further, it is covered with an interlayer film 6 made of a silicon oxide film, and formed with a thin aluminum film in a predetermined pattern, thereby forming signal wirings 7. The aluminum particle size of the film 5 is formed smaller than those of the wirings 7. Accordingly, if particles are emitted during the annealing after the formation, the particles entering a photodetector are small, and thus, the influence on the photodetecting area of the photodetector is substantially eliminated. In this manner, it can prevent its sensitivity from decreasing.

Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the transmission of undesired packet data to the PHS (registered trademark) terminals and to improve the using efficiency of frequency in a radio section. SOLUTION: Radio base stations 21 to 23 convert the telephone numbers of their connected PHS terminals 11 to 13 into the MAC addresses to notify a PHS server 31 of these addresses. A server 31 decides and authenticates the connection requests of terminals via an IP/MAC address management part. When a PHS terminal is connected, the server 31 manages both IP and MAC addresses of the terminal and notifies every radio base station of the MAC address information on the terminal. Every radio base station holds the received MAC address information and filters the packet received from an Ethernet (registered trademark) 40 to send it to a radio section.  The server 31 also sends the broadcast signals to the radio section in a prescribed cycle and updates the MAC address table information, based on the answer given from every PHS terminal to notify every radio base station of the updated table information.
