Title: Gas laser device
Inventor: TERAI KIYOHISA
IPC: H01S3/23
Filed: 1989-01-30
Abstract: PURPOSE:To obtain a laser light having excellent laser working by connecting a plurality of laser media in series, and altering the timing of a voltage to be applied in synchronization with the dischargers. CONSTITUTION:A laser power source 17a is controlled by a controller 9 to apply a pulselike voltage between both electrodes of a laser media 12A to obtain a pulse laser light 19a having, for example, a wide rectangular waveform. Simultaneously, a laser power source 17b is controlled to obtain a laser light 19b having, for example a lightly shorter rectangular waveform. Then, when the timings and periods of the rise of both the pulses are synchronized, both the pulses can be superposed to obtain a pulselike laser light 19 having an abrupt rise. The directions of the laser gas flows 13A, 13B of two laser media are reversely set to supplement the timing change of refractive index of a discharging space due to the density gradient of upper and lower laser gas flows generated at the time of pulsation. Thus, variation in the optical axis of an output laser light can be suppressed, and the accuracy of a cut work can be also raised.

Title: Controller for movement of optical lens
Inventor: TANIGUCHI AKIHIKO
IPC: G03G15/04
Filed: 1985-01-29
Abstract: PURPOSE:To improve the movement position accuracy of an optical lens by driving a stepping motor according to magnification information and positioning the optical lens at a slit position corresponding to the magnification information with a slit signal from a sensor. CONSTITUTION:A control circuit 20 drives the stepping motor 16 clockwise (CW) or counterclockwise (CCW) according to input information, specially, magnification information from an operation part 21 provided to a copying machine body. Consequently, the optical lens is positioned at the slit position 19 corresponding to the magnification information with the slit signal from the sensor 17. In this case, the optical lens 3 is inhibited from moving unless copying operation is performed or while the copying operation is performed even when the power source is on. A four-pole, two-phase excitation system is employed to drive the stepping motor 16, obtaining the position precision of each step. Consequently, the movement position accuracy of the image- forming lens is improved according to copy magnification.

Hot water and steam are successively sent into the tank 1 from sources 13, 14, by which the tank is washed. The oil-contg. waste water floated by this is sent through a suction 16 then through a storage tank 17 into a separating column 20. Here, the waste liquid is subjected to pressurizing, heating and stagnating treatment, and the oil separated by the repetition of these is circulated into the tank 9 and the roughly separated water into the tank 1. This is repeated and the waste liquid in the tank 1 after the end of the steam washing is sent directly into the column 20, where it is subjected to final oil-water separation, and the oil is pumped into the tank 9. The roughly separated water is successively filtered in PP-crimped fiber-, active carbon packed columns 25, 28, thence it is released.

Filed: 1990-01-29
Abstract: PURPOSE:To obtain a package with a hooking hole which is not liable to a large deformation in its shape by a method wherein a through hole for hanging purposes is formed at the upper part of the package containing an object and a reinforcing member is provided around the through hole. CONSTITUTION:Both the side edges of a package 35 containing an object 1 are seal cut and the upper and lower ends thereof are heat sealed in a predetermined seal width. A through hole 60 is formed at the central part of a tab 35a of the upper part sealed in a relatively large width. The tab 35a is provided with a reinforcing member 41 interposed between two films 20 and 22 and having the almost same width as those of the films. Since the reinforcing member 41 is thus located around the through hole 60, even if a force is exerted radially from the interior of the through hole 60 to the exterior thereof, the tab can resist to such force with the reinforcing member 41. Therefore, if both the films 20 and 22 are to be formed of an inexpensive uniaxially stretched material, the through hole 60 is not liable to a deformation in its shape.

Abstract: PURPOSE:To enable evaluation of aiming with high accuracy by a method wherein a difference between the present position of a moving target or an aiming point, which is determined by the aiming, and the actual present position of the moving target is confirmed by the irradiation of laser and the detection of reflected laser beams. CONSTITUTION:An aiming mechanism 1 determines the position of a target by aligning the lien of sight 101 or an aiming point with the present position of the moving target 6 and outputs the command of firing or a trigger signal 102. The aiming point and the position of the moving target 6 coincide with the control information of a controller 2 through a control signal 201. A laser projector 3 inputs the trigger signal 102 and projects laser beams 301 against the moving target on the line of sight 101 at that time. A laser detector 4 detects reflected laser beams 401 after inputting the signal 102 and measures the time delay and the strength of the reflected laser beams 401, then, outputs an impact judgement result 402. When the aiming is not proper, the moving target 6 is not on the line of sight 101 and, accordingly, the laser beams 301 will not be reflected after hitting the target 6.
