Title: Asynchronous arithmetic unit
Inventor: ENDO YUKIO
IPC: G06F7/00
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To unnecessitate the initializing operation of an arithmetic unit in continuous calculation and to improve arithmetic efficiency by interrupting an arithmetic loop after detecting the last loop of calculation and permitting the initialization of an arithmetic block except a last stage to be in an ended or started state at the point of time when calculation is ended. SOLUTION: A last loop detecting circuit 35 outputs a last loop detecting signal at the point of time when calculation is executed in the last loop so as to establish the output of the arithmetic block 2, a control circuit 31 changes- over a loop selector 32 into an input latch 33 side and the loop is disconnected. When calculation proceeds and the output of the arithmetic block 5 is established, an arithmetic end detecting circuit 10 outputs an arithmetic end detecting signal and the output of the arithmetic block 5 is latched by an output data latch 30. At this time, the loop selector 32 is at the input data latch 33 side and calculation is temporarily stopped here. In this state, the respective arithmetic blocks 1-4 except the last stage arithmetic block 5 are in a state where whole initialization is ended or initialization is under execution.

IPC: H01S3/082
Filed: 1992-11-24
Abstract: PURPOSE:To enhance the performance of an apparatus by a method wherein a shielding plate as a mode selector restrains that a temperature rises due to irradiation with a laser beam, the damage of the shielding plate itself is prevented and the dew condensation of an optical instrument in the circumference is prevented. CONSTITUTION:A shielding plate 11 and a holder 15 for protection use are indicated. The holder 15 is composed of a case 16 and a cover 17. The shielding plate 11 is composed of a ceramic whose main crystal phase is fluorine mica, and it is provided with a hole in a very small diameter in order to limit the luminous-flux diameter of a laser beam. The reflection factor of the ceramic with reference to the laser beam is high, and the ceramic is provided with a highly heat-resistant property. When the laser beam is passed through the hole, the circumference of the hole in the shielding plate 11 is irradiated with one part of the beam, but the beam is reflected here sufficiently, the laser beam penetrates well through the shielding plate 11 and the laser beam which is absorbed here is reduced. Since the shielding plate is durable against heating due to the reduced laser beam, it is possible to achieve its aim.

IPC: G03F1/40
Filed: 1992-10-28
Abstract: PURPOSE:To prevent an etching defect and pinhole defect with the method for production of the photomask by selectively etching a hard blank. CONSTITUTION:Desired resist patterns 14A are formed to the hard blank formed with a light shielding material layer 12 consisting of chromium, etc., on the surface of a mask substrate 10 consisting of glass, etc.; thereafter, pure water is spray dipped atop the patterns in order to facilitate the infiltration of an etching liquid into microholes 14a.

Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To hold the reading and writing accuracy by performing a moving operation by a motor which is capable of controlling rotation speed to smooth the moving speed of a reading and writing combined head. SOLUTION: A rotation part 6 has a bracket 6a and a gear 6b. A ball clutch part 7 is a mechanism for selecting whether rotational force is transmitted to the rotation part 6 or not. When the rotational force is transmitted to the bracket 6a through the gear 6b by this action, a head 4 is rotated. Further, a motor 8 is a power source for rotating the reading and writing combined head 4a and securing the position and the motor is engaged with the gear 7a of the ball clutch part 7. The driving force from the motor 8 is slowly transmitted to the rotation part 6 by the ball clutch part 7. As a result, the impact received when the rotation of the bracket 4 fixing the head 4a is stopped can be reduced.
