Title: Multi-laser beam source device
Inventor: MIYAGAWA ICHIRO
IPC: H01S5/00
Filed: 1987-11-10
Abstract: PURPOSE:To enable laser beams to be composed together into a single beam at a required position by a method wherein the laser beams different from each other in wavelength are made to be composed together through a prism provided with a wavelength dispersion property. CONSTITUTION:Laser beams 2, 2', and 2'' are made to penetrate an incidence lens 6 to be parallel with each other and incident on a prism 7 from directions slightly different from each other. The prism 7 is previously selected from prisms which are provided with a wavelength dispersion property that enables the prism to project three beams which are different from each other in wavelength and incident on from directions slightly different from each other respectively onto the same optical path. The laser beams 2, 2', and 2'' which penetrate the prism 7 are composed into a single beam, which is incident on a galvanometer mirror 8 provided onto the optical path. Therefore, the laser beams 2, 2', and 2'' are made to be equal to each other with regard to the condition under which these beams are reflected by the galvanometer mirror 8, so that such a trouble as the reflective condition is made to varies corresponding to each beam due to the surface accuracy of the galvanometer reflective face can be eliminated. By these process, all beams are made to be focused on a convergent point P and an accurate composition of wave can be realized.

Title: Power system employing vacuum trigger gap device
Inventor: TAKAHASHI HIDEOMI
IPC: H01H33/66
Filed: 1987-11-12
Abstract: PURPOSE:To achieve a good and stable switching operation continuously, by controlling time for feeding trigger current to a trigger electrode based on an output from a main current detecting section. CONSTITUTION:Upon provision of an operation start command from outside to a command terminal 16, a control section 14 operates to feed trigger current IT from a trigger electrode 12 between a trigger electrode 7 and a main electrode 4b so as to conduct a pair of main electrodes 4a, 4b. Consequently, main current IM is fed from a main power source 10 to a load 13 then it is detected through a main current detector 15 and provided to the control section 14. The control section 14 controls the trigger power source 12 to keep operating condition so that the trigger current IT is fed continuously until the main current IM reaches a predetermined level IC. Since main electrodes 4a, 4b are conducting through low resistance, the main current IM increases even for a large inductive load and finally such condition as IM>=IC is brought out to provide stable discharge and establish conducting state between electrodes so as to stop operation of the trigger power source 12 through the control section 14. Thereafter, the main current IM stays in a stable discharge zone to maintain conducting state thus establishing switching operation.

IPC: G07D7/00
Filed: 1990-10-24
Abstract: PURPOSE:To enable secure oblique feed detection by finding the mean position of several points on a side of the paper, etc., on one end side and the mean position of remaining point on the other end side and detecting the oblique feed of the paper, etc., from the difference between the two mean positions. CONSTITUTION:A position detection sensor 3 which can detects the position of the paper, etc., over a range wider than the width in the direction perpendicular to its conveyance direction finds many points on the sides of the paper, etc., over a wide range and determines the position and oblique feed quantity of the paper, etc., according to the position of those many points. Then a paper end detecting means 32 detects the position of plural points on the sides of the paper, etc., and an oblique feed detecting means 54 divides the points on the sides into two, i.e. one end side and the other end side and finds the mean position A of the points on one end side and the mean position B on the other end side. Consequently, the influence of an error due to the breaking of the paper, etc., included in the respective points on the sides of the paper, etc., is reduced and the oblique feed component is extracted effectively in the form of deviations from the mean position A and mean position B.

Inventor: OKADA KOJI
IPC: G06F1/04
Filed: 1990-10-23
Abstract: PURPOSE:To shorten the drawing control unit of a bus cycle and to improve throughput by controlling the bus cycle by a clock signal with frequency higher than the system clock frequency of a microprocessor. CONSTITUTION:A clock CLK1 in which an input clock CLKIN with frequency higher than the clock frequency of the inside of the microprocessor is 2-fre quency divided, a clock CLK2 in which it is 4-frequency divided, a system clock CLKS in which it is 8-frequency divided are stopped at a level 1 in a wait period TW, respectively. During that time, the input clock CLKIN continues the sampling of a bus cycle control signal RDYI as a sampling pulse S2. When the RDYI is changed to a level 0, the D flip-flop 14 of a sampling circuit 1 is inverted again and a level goes to the level 1, and a wait signal WT1 is set in an inactive state, and also, it is applied to frequency division control logic 2, which passes the input clock signal CLKIN again, therefore, the fre quency dividing operation of a frequency division circuit 3 can be restarted. In such a way, the prolongation control unit of the bus cycle can be shortened, which improves the throughput.

Abstract: PURPOSE:To obtain a pulse signal of 50% of the duty ratio by shifting the ratio of forming angle area of a light shielding section to a light transmitting section of a rotating disc from 1:1 and controlling the forming angle area of the light shielding section and light transmitting section, thereby correcting the timing of light receiving operation. CONSTITUTION:When a light receiving section 25 performs a light receiving operation even if an opening rate of a window section 25a is less than 50%, a tooth section 22 is formed in a forming angle area larger than a notch section 23. While, when the light receiving section 25 doesn't perform light receiving operation unless the opening rate of the window section 25a is more than 50%, the tooth section 22 is formed in the forming angle area smaller than the notch section 23. At that time, the forming angle area of the tooth section 22 increases as the opening rate of the window section 25a performing the light receiving operation of the light receiving section 25 decreases.
