Title: Method for controlling phase controller
Inventor: NAKAMURA TAKEHISA
IPC: G05B11/28
Filed: 1990-09-27
Abstract: PURPOSE:To exactly control the phase of a controlled system with high accuracy even when a power supply frequency is fluctuated by correcting a PWM signal for operation by measuring a wave height range corresponding to a maximum wave height value. CONSTITUTION:The wave height range corresponding to the maximum wave height value of a lamp voltage is measured by a trigger signal generation circuit 13 and a measuring signal output circuit 17, and the frequency of a power supply voltage is indirectly measured. In this case, a control circuit 9 stores the contents of the PWM signal corresponding to an inputted measuring signal into a RAM 9c and outputs the PWM signal with the stored PWM signal contents as the 100% operation output range. Further, the output of an output inhibiting signal is stopped so as to output a trigger signal from an output switching circuit 15 to an operation output circuit 19, and the operation output circuit 19 outputs the power supply voltage to a heater from the output of the trigger signal to the turn of this signal to 0 level in each half cycle period of the power supply voltage. Thus, even when the power supply frequency is fluctuated, the phase of the controlled system can be exactly controlled with high accuracy.

IPC: G11B7/26
Filed: 1986-10-29
Abstract: PURPOSE:To eliminate the instability of an arrangement of a pit train to between guide grooves and to reduce crosstalk, by switching the guide groove and the pit train at every other rotation of an optical disk master disk, and executing the exposure by a laser beam. CONSTITUTION:A guide groove 3 is brought to cutting in the peripheral direction from an arbitrary point C between a point A of the rotation center of an optical disk master disk 1 and a point B of the outside peripheral edge, and returned to the outside position of the start point C in a state shifted by a pitch P, by the rotation of the master disk 1 and the feed in the radial direction. A cutting signal is switched to a pit signal as soon as it reaches an A-B line, goes round while drawing a spiral, and as soon as a pit train 4 reaches the A-B line, the cutting signal is switched to the guide groove 3 again. In such a way, by executing alternately cutting of the guide groove 3 and the pit train 4, intergroove recording in which the pit train 4 is inserted and held by the guide groove 3 is executed. Accordingly, a highly reliable optical disk medium for scarcely generating crosstalk is obtained.

That is, the region 2 is made lower so that even if an insulating film and an electrode film of a multilayer interconnection are stacked on the region 2, a liquid, such as a photoresist, an SOG layer or the like, can be applied thinly and uniformly. In such a way, the region 2 is previously etched so that the region 2 becomes lower than the regions 3 and a step difference between the region 2 and the regions 3 is made small. Thereby, when the liquid, such as a resist or an SOG layer like, is applied, a film, which has no coating unevenness and is uniform, can be obtained.

Title: Gas laser oscillating device
Inventor: MOTOMIYA HITOSHI
IPC: H01S3/038
Filed: 1989-09-29
Abstract: PURPOSE:To prevent a laser device from lessening in output over a long term so as to obtain a stable laser beam by a method wherein a metal electrode is formed of a sintered alloy mainly composed of an alloy of chrome, iron, and nickel and an insulator of alumina, silicon dioxide, or the like. CONSTITUTION:A metal electrode is formed of a sintered alloy mainly composed of alloy particles 21 of chrome, iron, and nickel and alumina particles 22 of insulator. Therefore, electrons -e are uniformly emitted from the alloy particles 21 of chrome, iron, and nickel existing among the alumina particles 22 to enable a glow discharge to start stably. At this point, as the alumina particles 22 are oxide, they are hardly oxidized, so that the surfaces of the alloy particles 21 of chrome, iron, and nickel where electrons are emitted are not screened by oxide, and oxide is never scattered, whereby the inside of a discharge tube is protected against pollution. Moreover, an oxide film 23 of the alloy particle 21 of chrome, iron, and nickel is thin and electrically conductive, so that an electron emitting plane hardly deteriorates and a discharge is stabilized. By this setup, a laser device of this design can be prevented from lessening in output over a long term to output a stable laser beam.
