Patent JP-H07297482-A (JP)
Title: Semiconductor laser device
Inventor: BESSHO YASUYUKI
IPC: H01S5/00
Filed: 1994-04-27
Abstract: PURPOSE:To provide a semiconductor laser device capable of outputting a laser beam of small aspect ratio, without increasing the oscillation threshold current and damaging end surfaces. CONSTITUTION:The widths in the horizontal direction of ridge end portions R1, R2 in the vicinity of end surfaces are made narrower than the width in the horizontal direction of the ridge central part R3. Thereby the width of an optical waveguide on the end surface is narrowed, while the element resistance of the ridge central part R3 is kept low. As the material of an N-current block layer 13, GaInP having a band gap larger than that of GaAs is used. Thereby light absorption of the end surface is reduced.

Title: Paper ending control device of draw-out machine
Inventor: IKEMOTO HIROSHI
IPC: B65H19/18
Filed: 1984-05-04
Abstract: PURPOSE:To eliminate the trouble of after processing by always starting to press a paper ending roll to a pasting position at a preset position, and regulating the overlapping length of old and new original paper. CONSTITUTION:After a paper ending command signal A is output, in T seconds after detecting the first pasting position, a start signal C for operating a paper ending roll is output, and a paper ending roll 4 is operated by an actuator or the like to be pressed to a symmetrical position separated from the pasting position by 180 deg.. Similarly, a cutter 13 is displaced at the point of time when a start signal D for operating the cutter is output extending over t2 hours to cut the trailing end of the old paper. This position is behind the paper ending roll 4 pressing position by t/2+t1, and the cutter operation time t2 is expressed by t2=(n+1)t+t1-P10. Thus, T+t0 seconds later behind the first pasting position, the paper ending roll 4 is started to press to a new original paper roll, and further t/2+t1 seconds later, the trailing end of the old paper is cut to regularize the over-lapping length of old and new original paper rolls.

Title: Engaging means
Inventor: MORITA TAMAO
IPC: H01G7/02
Filed: 1985-04-27
Abstract: PURPOSE:To obtain the titled engaging means having a magnetic shielding property at low cost by a method wherein a ferromagnetic metal film and a synthetic resin film are applied in a laminated form on the outer circumferential surface of a permanent magnet. CONSTITUTION:The ferromagnetic member 2 spliced on the pole-face (a) of a permanent magnet 1 having a hole 1a and the ferromagnetic member 3 which comes in contact with a pole-face (b) are constituted in such a manner that they are detachably attracted through the intermediary of the hole 1a of the permanent magnet 1. A ferromagnetic metal film 5 and a synthetic resin film 6 are applied in a laminated form at least on the pole-face (b) and the outer circumferential surface (c) of the permanent magnet 1. On the engaging means constituted as above, the ferromagnetic metal film 5 constitutes a magnetic path when the engaging means is in a non-engaged state, and as the lines of magnetic force leaking to outside is reduced by the film 6, the breakage of record can be prevented even when a magnetic recording card and the like approaches. Also, as attracting force is concentrated at the center of the ferromagnetic member, the lowering of attracting force can be prevented by the films 5 and 6.

Filed: 1989-04-10
Abstract: PURPOSE:To obtain a sharp eyeground photograph even at the time of special projection using illumination light of a peculiar wavelength region by properly correcting the shift of a focus matching position corresponding to the selection of an imaging method by a focus matching correction means. CONSTITUTION:A light source 34 is allowed to light at the time of automatic focus matching and a mirror surface 15a is inserted in a light path. The luminous flux emitted from the light source 34 is incident to an eye E to be examined through an objective lens 2 and a bright line image is projected on the eyeground Ef or on the front or rear thereof. The near infrared ray component in the reflected light of the bright line projected on the eyeground Ef is reflected by a wavelength splitting prism 5 to be again formed into images on position sensors 48a, 48b. A controller 43 calculates the difference between an image interval (d) and a reference image interval d0 and a stepping motor 41 is rotated so as to eliminate this difference to allow a focus to coincide automatically. When a barrier filter 6 is inserted at the time of special projection, a microswitch 49 is closed and the controller 43 detects this state to alter the reference image interval from d0 to the value determined corresponding to the difference of a focus matching position and rotates the stepping motor 41 so that the interval of the bright line images on the position sensors 48a, 48b becomes equal to a predetermined value to obtain a focus matching state.
