CONSTITUTION:Class B-F amplifier stages are formed as units, the plural units 1-1, 1-2,... are connected in parallel and a control circuit 9 controlling the supply of a power supply 5-1 to each unit individually is provided. A matching circuit 4-1 is provided to the input of the class B-F amplifier stage 1-1 and a matching circuit 3-1 is provided to the output side, and the other amplifier stages 1-2... have similarly matching circuits, then the control circuit 9 is closed to apply the voltage from the power supply 5-1 to all the amplifier stages for the operation, then a maximum output is obtained at a signal output terminal 8. Then the control circuit 9 is controlled to turn on the power supply for the class B-F amplifier stage 1-3 giving a comparatively large output, then the output of the amplifier stages is nearly halved, for example. In this case, the other amplifier stages are operated still efficiently because of the presence of the matching circuits 3, 4, and only the maximum output is halved.

Filed: 1989-09-20
Abstract: PURPOSE:To stop the shift step of a chain of each flip-flop at a desired timing and to confirm the operation of each flip-flop by providing a control flip-flop for controlling a shift operation. CONSTITUTION:When a control flip-flop FF1 is set by turning on a debug command and becomes a debug mode, a debug trigger is sent out from an AND circuit 14, and an AND circuit 16 sends out a set signal to a control flip-flop FF4. At the time of a debug mode, an AND circuit 17 sends out a reset signal to the FF4, whenever an A clock is inputted. Accordingly, the FF4 is set, whenever the debug command is turned on and an enable loop shift signal is allowed to rise, and allowed to fall by a reset signal immediately thereafter. In such a way, the shift step of a chain of each flip-flop is stopped at a desired timing, and the operation of each flip-flop can be confirmed.

Abstract: PURPOSE:To widely decrease the number of parts and to make the device small in size and light in weight by using the dividing hologram optical element as the means to separate the reflecting beam from a disk surface from the incident beam onto the disk surface. CONSTITUTION:The beam projected from the semiconductor laser is converted so that the wave surface can be focused by a grating lens 11 for focusing, and made incident on a grating 12 for dividing. The light of about 50% out of it receives the conversion of the wave surface by the grating 11 for the dividing, is separated in two directions, these light fluxes are focused by the grating 11 for the focusing again, and the focusing position comes to be two points away from the semiconductor laser spatially by the effect of the wave surface conversion by the grating 12 for the dividing. The focused light is photodetected by the photodetecting device located at respective focusing points, and therefore, by summing up the output of these detecting devices, the disk information can be read. Thus, since the dividing of the beam is executed by using the diffracted ray and the vertical transmitted wave of the hologram optical element, the device can be obtained which has a small number of parts and is small in size and is inexpensive.

Abstract: PURPOSE:To make a limit cutting thickness thick and increase limit cutting speed in a method for cutting a metallic material such as aluminum with a laser beam by spouting assist gas from a preceding nozzle, with a gradient in an oblique rear direction to the cutting schedule path of the metallic material. CONSTITUTION:During a cutting operation, assist gas 1b from a preceding laser nozzle 1, is spouted out with a gradient in an oblique rear direction to the cutting schedule path of a metallic material W. Consequently, before a molten metal produced by the irradiation of a laser beam 1a from a preceding nozzle 1, solidifies, it is blown out far back by strongly receiving the action of this assist gas 1b. Accordingly, the schedule position of the attachment of spatters on the bottom surface of a blind groove 3 formed by the irradiation of the preceding laser beam 1a, is aperted far back relatively from the irradiation position of the preceding laser beam 1a. Therefore, cutting performance by the irradiation of a succeeding laser beam 2a, is improved, and a depth of cut, is deep.
