Filed: 1995-06-27
Abstract: PURPOSE: To provide an objective lens driving device capable of reading/writing optical disks with different characteristics with a device by loading plural optical characteristics being optical elements such as an objective lens, etc., and making them switchable. CONSTITUTION: A movable body 5 provided with objective lenses 8a, 8b and driven by a focus coil 9 in the thickness direction of an optical disk 1 is carried vertically movably and rotatably with a rotary shaft 7 fixed to the movable body 6 driven in the direction orthogonal to the thickness direction. The optical disk 1 is irradiated by a laser beam LB through the objective lens 8a before recording/reproducing is started, and the operation reading a disk attribute is performed for a fixed time, and the propriety of reading is judged, and when the reading is impossible, the movable part 5 is rotated, and the objective lens 8a is replaced with the objective lens 8b, and the operation reading the disk attribute is restarted. Thus, the objective lens driving device capable of reading/ writing the optical disks with different characteristics with one device is obtained.

Title: Wire dot color printer
Inventor: SUMIYA SHIGEAKI
IPC: B41J2/25
Filed: 1991-07-01
Abstract: PURPOSE:To reduce the turbidity of a color due to color mixture by making the surface of a wire ink-repellent in a color printer transferring the ink of an ink ribbon to an object to be printed by driving the wire to form a pixel. CONSTITUTION:For example, an ink repelling layer 103 composed of polytetrafluoroethylene is provided to a wire 101 in order to impart ink repelling properties inferior to the wettability to ink to the surface of a wire core material 102, for example, composed of tungsten. When the wire 101 is driven in the direction of a platen 204, paper 203 and an ink ribbon 202 are held between the wire and the platen 204 to transfer ink to the paper 203 from the ink ribbon 202. Since the wire coming into direct contact with the ink ribbon is made ink-repellent, even when the same wire comes into contact with the ink ribbon of a different color, the color turbidity due to the mixture of respective colors is not generated and a beautiful color is kept indefinitely.

Title: Valve seat and valve
Inventor: HIRAOKA TAKESHI
IPC: B22F7/02
Filed: 1978-12-21
Abstract: PURPOSE: To improve wear-resisting property and strength of valve, by making the contact area of the valve and valve seat with an iron type sintered alloy including one or more hard-phase forming elements, and selecting hardness, size and quantity of the hard phase and the overall hardness respectively within a specific range.  
     CONSTITUTION: Contact area of valve seat and/or valve is made of iron type sintered alloy which includes one or more hard-phase forming elements. Here, it is required that hardness of the hard phase is within the range of HV800W1800 and its quantity is 5W70% by area ratio. As the size of the hard phase, more than 70% of the entire particles constituting the hard phase have sizes of 1W150μ. It is required further that the hard phase has a void ratio of 0.5W30% and its overall hardness is HRC25W50. With such an arrangement, sufficient wear-resisting and heat-resisting property is given to the valve if it is used in a diesel engine which is operated under severe operational conditions. Further, since padding of stellite alloy or the like is not required, such a valve can be manufactured economically and with high productivity.

Title: Method for controlling optical disk device
Inventor: MORITOMO ICHIRO
IPC: G11B20/18
Filed: 1991-06-06
Abstract: PURPOSE:To exclude the influence of defective sectors when two pass recording mode is performed at the time of data recording by extracting all defective sectors at the time of initializing a recording medium. CONSTITUTION:At the time of initializing the recording medium, the initialization data is recorded by three pass operation mode concerning all sectors; simultaneously the defective sector information then discovered and the performance of the verifying operation concerning all recording areas are recorded in the recording medium; based on this defective sector information, a sector changeover operation is performed; and the data recording is performed for each sector by two pass operation mode. Consequently, at the time of initializing the recording medium, the defective sectors are all extracted, and therefore, even if the two pass recording mode is performed at the time of data recording, the influence of the defective sectors is excluded. Also, when the device errors are generated during the recording operation, as the verifying operation is previously performed on the sectors being recorded, the reliability in the data recording is improved.

Abstract: PURPOSE:To instantly display a desired teletext program out of a memory through a simple operation by storing a program index information and a channel number from a TV video signal so that a teletext program can be selected through an operating section while said information and the number are displayed. CONSTITUTION:A tuner 2 is actuated via a microcomputer 16 by the operating rection 17 to select a channel, and an image is displayed on a CRT 13. A video signal is outputted from an amplifier circuit 4, digital-processed in a character extraction circuit 14, and character information is recorded in a character signal recording memory 15 corresponding to multiplex H. The microcomputer 16 reads it at a time other than a recording time, and sequentially compares thus read out information with information in a backup memory when the information is index information, and when they coincide with each other, updates only time information by the information from a timer 24. In case of discrepancy, the computer 16 updates the recording in the old index area. By such a constitution, the information of respective channels is stored in the backup memory 23, and the information can be instantly viewed, hence the program selection can be achieved by an operator while viewing the index, and in case of overflow of the memory 23, data is transmitted to a main memory 19 of large capacity, therefore the operation is not obstructed at all.
