Title: Optical disk library device
Inventor: YOKOYAMA YOSHIHIRO
IPC: G11B19/02
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To accelerate the data transfer speed on the average, to secure high minimum performance with a small number of drives, and to reduce cost by writing data a half of the drives from the outer peripheries of optical disk media and writing data to the rest half of the drives from the inner peripheries. SOLUTION: A next writable block position on an optical disk medium set on a drive is read out (procedure 201). It is decided which of the outer and inner peripheries of the disk medium data are written from (procedure 202). For example, when the data are written from the inner periphery, blocks which are written from the write block position are counted (procedure 208). The number of blocks is calculated to obtain a constant read/write time without depending upon each read/write block position. The block position where the data are actually written is recalculated (procedure 203). A writable block position is calcuated (procedure 204). A processor issues an instruction having the calculated parameter to the drive (procedure 207).

Title: Artificial fuel cube and manufacture
Inventor: REIMONDO EDOWAAZU
IPC: B30B11/20
Filed: 1982-07-29
Abstract: The densified fuel cubes are made by extrusion from a roller and ring apparatus, of the waste matter which is fed into the apparatus as a mass of pulverized carbonaceous matter having a particle size not exceeding 3/8ths inch. The fuel cubes have a bulk density of between 30 and 60 pounds per cubic foot and a heat value of not less than 8000 btu. The fuel cubes (150) are broken off, on issuing radially outwardly from horizontal and circumferentially disposed extrusion passages, of stationary die means (90) which are clamped between plates (23, 25). The extrusion is effected by wheels (rollers) (66, 68), which freely rotate on spindles (69), mounted upon a driven shaft (40) for orbiting rotation radially interiorly of the die means (90). The pulverised matter is gravitationally fed at an inlet (21), onto an inverted feed cone (45) which is also rotated by the shaft (40), and carries paddles (49) which distribute the matter to fall through apertures (51) of the upper plate (23), into the path of the orbiting rollers (66, 68). The die passages are longitudinally grooved to increase compacting friction on the matter. <IMAGE>

Abstract: PURPOSE:To restore occurrence of a data error immediately and automatically by inserting an image frame subject to compression coding in an in-frame coded mode to a video signal sent to a receiver side for each prescribed number of frames. CONSTITUTION:After a video signal is converted into a digital signal by an A/D converter 1, data are rearranged by a format converter 2 and the resulting data are compression-coded by an image compressor 3. A timer 4 counts number of received frames and provides an output of a refresh signal for each prescribed frame number. Upon the receipt of the refresh signal, the compressor 3 is switched to the in-frame coding mode for the transmission of one frame and a new frame is sent. An audio signal is converted into a digital signal by an A/D converter 5, the converted signal is compression-coded by a voice compressor 6 and its timing is adjusted by a delay device 7 in matching with the video signal. The audio signal and the video signal are multiplexed by a multiplexer 8 and the result is fed through a signal line to a coder 9, in which the signal is subject to error correction coding processing, and the resulting signal is sent to a transmission line.

Besides, the frequency of the gain crossover of the first or the second tracking servo system is set to the frequency of the speed of the revolution of the optical disk 1 or more. Therefore, the gain of the second tracking servo system is set larger than the gain of the first tracking servo system near the rotating frequency of the disk 1. Besides, the displacement of an objective lens 8 by the first tracking servo system with respect to an incident luminous flux is restrained within a prescribed range. Thus, the gain of the tracking servo system from being lowered and stable tracking servo is realized.

Abstract: PURPOSE:To enable plating of a through-hole to be improved by obviating the defects to occur caused by this process by a method wherein the cleanness of the facilities concerned is maintained, while the solutions containing many kinds of electrolytic ions are prevented from mixing with each other. CONSTITUTION:When an automatic travelling device 2, which transfers a printed circuit board, approaches a sensor 6 attached to a transferring rail 4, the sensor 6 is actuated so as to open a magnetic valve 9 provided midway on a tap water piping 10 for a rinsing vessel 8 so that tap water is spouted out from spray nozzles 11 and tap water pipes 10 provided above baffle plates 12. Next, the automatic travelling device 2 receiving signals from a control panel pulls down the printed circuit board 1 into the rinsing vessel 8 so as to rinse the substrate 1 with the sprayed water. During rinsing the substrate 1, water, sprayed up, hits against the baffle plates 12 and then drops down into the rising vessel 8, therefore dirty water is prevented from mixing with the solution containing electrolytic ions in an adjacent plating tank. By these processes, a plating film formed on the wall of a through-hole can be prevented from producing defects.

SOLUTION: The signal light and idler light of the two wavelengths are amplified by passing the inside of a resonator composed of an exit side mirror and a total reflection mirror back and forth, by which the oscillation is generated. The exit signal light and the exit idler light are then emitted from the exit side mirror. At this time, a Ti:Ai2 O3 laser crystal 204 is excited by using the second harmonic wave of Nd:YAG laser as an exciting is beam C. A piezoelectric element 210 is driven by controlling the frequency of an RF power source 208 according to the wavelength of the exit laser beam desired to be emitted as the exciting light A from the exit side mirror 200. Then, only the light of the wavelength according to the frequency of the RF power source 208 is amplified and the laser oscillation is induced.  The emission of only the exit laser beam of this wavelength as the exciting light A is made possible.
