Title: Laser oscillating apparatus
Inventor: FUKAYA KUNIAKI
IPC: H01S3/097
Filed: 1988-09-07
Abstract: PURPOSE:To cope with cutting requirements in a broad range by making the rotating speed of a Roots blower variable with an inverter, and performing laser operation from a low-speed gas flow to a high-speed gas flow. CONSTITUTION:In a laser oscillating apparatus using a Roots blower 1, the flow speed of a gas flowing through a discharge tube 4 depends on only the rotating speed of the Roots blower 1. Namely, when the rotating speed of the Roots blower 1 is changed with an inverter 7, the flow speed of the gas flowing through the discharge tube 4 can be controlled from the low speed to the high speed. The command for this operation can be imparted based on a machining program or can be set with parameters and the like. As a result, the low-speed gas-flow type and high-speed gas-flow type laser oscillations can be performed by one apparatus. In this way, cutting requirements of metal materials in a broad range can be handled.

IPC: G02B26/10
Filed: 1990-08-28
Abstract: PURPOSE:To make the write start of the image data of respective colors coincide with the change of the speed of the driving roller of a belt-like photosensitive body and to prevent the position of an outputted image from being deviated by setting the circumferential length of the driving roller to be integral multiple with respect to the moving quantity of the belt-like photosensitive body in the interval of the cycle of a timing pulse. CONSTITUTION:Respective loads are controlled by the timing pulse obtained by frequency-demultiplying the synchronizing signal of a polygon mirror 5a, which scans the photosensitive body with a light beam, into (n) {(n) is an integral number including 1} based on the image data. Then, in the case that the photosensitive body is regarded as the belt-like photosensitive body 1 and the moving quantity of the body 1 in the interval of the cycle of the timing pulse is set to be (ln), the circumferential length of the driving roller 2 for driving the body 1 is set to be the integral multiple of the moving quantity (ln). Thus, the write start of the respective colors and the change of the speed of the roller 2 of the body 1 are made to coincide with each other and a color image forming device that the positional deviation does not occur to the outputted image is obtained.

Title: Ink dot printer
Inventor: OKUNO SHIGERU
IPC: B41J2/305
Filed: 1984-10-25
Abstract: PURPOSE:To maintain an dot forming ink quantity at constant level, improve printing quality and making printing condition uniform by forming an ink film to supply ink at the head of a needle and positioning the tip of the recording paper side of the head of said needle at the slightly protruded position on a recording paper side. CONSTITUTION:If a magnet is energized, ink is sucked up into a slit 31 between magnetic poles 30 to form an ink film 32 and a needle 24 to form dots is protruded on a recording paper side 12. At that time, the tip 34 of the needle 23 does not contact recording paper 12, but an electric field is generated in the needle by a power supply 54. As a result, ink 43 adhering to the tip 34 of the needle 24 near an electrode 47 is caused to fly toward the electrode 47 by the force of the electric field, forming dots on the surface of the recording paper 12. In this case, the edge of the tip 34 contacts the surface 35 of an ink film 32 during its stationary condition and causes no ripple in its film surface 35. For this reason, no ink between two needles 24 goes flying, even if the needles operated simultaneously.
