Title: Optical disk device
Inventor: OGASAWARA YASUO
IPC: G11B7/0045
Filed: 1986-04-18
Abstract: PURPOSE:To easily prevent double recording on an optical disk carrier by incorporating a non-volatile random access read/write memory (RAM) in a cartridge where the optical disk carrier is stored and recording information, which indicates whether each sector on the optical disk carrier is already recorded or not, in the RAM and reserving recorded area information in an optical disk cartridge unit.

Title: Magnetic recording and reproducing device
Inventor: SHIMEKI TAIJI
IPC: G11B5/09
Filed: 1982-05-27
Abstract: PURPOSE:To simplify the configuration of circuit and to reduce a crosstalk, by dividing plural tracks into plural groups, and using a write signal generating pulse of different phase for each group. CONSTITUTION:N pieces of magnetic heads 7-1-7-N are divided into M pieces of groups, so that magnetic heads of the same group are not placed adjacently to each other (M<N). A write current does not flow simultaneously to (M-1) pieces of magnetic heads of both sides of the magnetic head, therefore, the write current becomes 1/M of the simultaneous operation of N pieces. Since the adjacent tracks are not operated simultaneously, a crosstalk is executed only between tracks separated by (M-1) pieces, and is reduced. Since the phase of a write current of each track is made different, a delaying circuit becomes unnecessary, and the circuit configuration is simplified.

Title: Pid controller
Inventor: YODA TETSUYA
IPC: G05B11/42
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To facilitate the start timing of integration by detecting the timing of start of an integrating operation based on the change speed of a response output. SOLUTION: A PID arithmetic part 11 operates a control output 22 based on three kinds of values of deviation, the differentiated value of deviation and the integrated value of deviation outputted from a subtracter 15 and applies it to a controlled system 12. In this case, when it is discriminated based on the deviation a response output 23 becomes a value within a proportional zone set in advance, a 1st arithmetic means operates the control output 22 based on a proportional operation. At the time of this control, when a prescribed instruction is applied from an integration ON/OFF control part 14, a 2nd arithmetic means starts the integration of deviation and operates the control output 22 based on that integrated value, the deviation and the differentiated value of deviation.  Then, when a target value is changed higher, the 2nd arithmetic means starts the integration with '0' as an initial value but when the target value is changed lower, the integration is started while defining the integrated value before the decrease of the target value as the initial value.

IPC: H01S3/036
Filed: 1989-04-11
Abstract: PURPOSE:To absorb pressure pulsations induced by a blower to remove before they propagate to a laser resonator so as to improve a laser beam machining in quality by a method wherein a side hole possessed of a specific area is provided to an air guide section on the gas laser medium feed side of a laser resonator or the air guide section in the range including the side hole is covered with an outer case possessed of a specific crosssectional area. CONSTITUTION:A side hole 8, whose area is 0.5-1.1 times as large as the crosssectional area of a feed duct 6 which feeds a gas laser medium, to a laser resonator from a blower, is board in the feed duct 6, and a resonance box 9 is connected to the feed duct 6 through a connecting duct 91. The resonator box 9 has a crosssectional area twice or more as large as the area of the side hole 8, and the volume of the resonance box 9 is so set as to make a resonant frequency coincident with the basic frequency of pressure pulsations, where the resonant frequency is determined by the volume of the resonance box 9, the area of the side hole 8, the length of the connecting duct 91, and the sonic velocity of the gas laser medium. As the resonant frequency of the resonance box 9 determined by a Helmholtz's resonance principle is coincident with the frequency of the pressure pulsations, the energy of a pressure wave is trapped in the resonant box 9 and not discharged again toward the feed duct 6, so that the pressure pulsations are absorbed by the resonance box 9 before they propagate to the laser resonator 1.
