Inventor: HATSUDA TETSUYA
IPC: B41M1/42
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To permit the re-utilization of a material for an electrostatic printing plate and reduce the cost of the same by a method wherein the printing plate is provided with a conductive substrate, having a conductive layer on the surface layer of the same, and an insulating layer, formed on the conductive layer of the conductive substrate and capable of being removed by solvent. SOLUTION: An electrostatic printing plate 40 is provided with a substrate 41, consisting of a PET film or the like, and a conductive layer 42, formed on the surface layer of the substrate 41 through vapor deposition of aluminum and the like. Then, a thermal head is operated with respect to the electrostatic printing plate 40 by an electric signal corresponding to image information to transfer an image pattern on an insulating layer 43, capable of being removed by a solvent, on the conductive substrates 41, 42. Then, the insulating layer 43 of the electrostatic printing plate 40A is wiped off upon finishing the printing by solvent, such as acetone, IPA or the like, to remove only the insulating layer 43. According to this method, the conductive substrate, consisting of the substrate 41 and the conductive layer 42, can be utilized again.  Accordingly, the reduction of cost can be contrived.

Filed: 1990-11-21
Abstract: PURPOSE:To reduce particles in a chamber and prevent generation of irregular discharge by forming a film with molybdenum particles at the surface of an anti-deposition plate of an etching chamber. CONSTITUTION:A molybdenum particle film is deposited on an anti-deposition plate 6, this plate is then attached to the internal wall of an etching chamber 3 and argon gas is supplied into the etching chamber 3 through a gas supply ring 2 from a gas supply ring 1 to maintain the internal pressure. Thereafter, a high frequency is applied to an upper electrode 4 and a lower electrode 5 to generate argon discharge within the etching chamber 3 and to etch the surface of a wafer 7. In this case, an insulating film at the surface of etched wafer 7 splashes, but it attaches thereto through reaction with the molybdenum particles coated on the surface of anti-deposition plate 6. Thereby, the etched insulating film is never dropped and is accummulated on the anti-deposition plate 6. Accordingly, reduction of particles and irregular discharge can be prevented.

Title: Laser beam generation controller, laser beam generator, and control method thereof
Inventor: MASUDA HISASHI
IPC: H01S3/139
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To improve utilization efficiency of a laser beam, by reducing a frequency at which resonator length control is temporarily stopped. SOLUTION: A search control section 29 predicts a direction and searches a state in which resonator length control can be effected in the predicted direction. That is, when a servo temporary stop determination section 28 determines to temporarily stop the servo control of resonator length, the section 29 predicts, using a predetermined resonator length as a reference, a direction in which a time interval between the resumption of the resonator length control and the next temporary stop of the resonator length control becomes long from the direction of increasing the resonator length and the direction of decreasing the resonator length, and searches a state in which the resonator length control can be effected in the predicated direction.  Further, when the resonator length control is ready to be effected through the search, the section 29 informs the section 28 to that effect, and the section 28 resumes the servo control. As a result of these operations, the resonator length control is effected so that the same oscillation frequency can be provided again.

IPC: H02M7/5387
Filed: 1990-11-21
Abstract: PURPOSE:To suppress the voltage rise of an inverter device within an allowable range by switching the control signal from a drive signal to a conduction signal when a detected voltage rises beyond an allowable value while a motor is decelerated. CONSTITUTION:When the voltage detected by a voltage detecting means 15 exceeds an allowable value while a motor is decelerated, the output of an AND circuit 16 is inverted to a high level, since both outputs of a comparator 17 and the means 15 become high levels. As a result, the first change-over switch 18 is switched so that contacts 18b and 18c can be connected to each other. Under such condition, the decline (deceleration) of an output frequency (f) is stopped and the frequency (f) is maintained at a fixed level. On the other hand, when the voltage detected by the means 15 is within the allowable range, the output of the AND circuit 16 is maintained at a low level and the first change- over switch 18 is maintained in a state where contacts 18c and 18a are connected to each other, since the output of the voltage detecting means 15 is maintained at a low level. The output frequency (f) is controlled to follow a frequency command fc under such condition.
