Filed: 1982-12-08
Abstract: PURPOSE:To miniaturize a chip, reduce the manufacturing cost, and enable to reduce the price of a semiconductor laser by forming one laser resonator by means of two active region stripes and two reflection mirrors. CONSTITUTION:The two active region stripes 6' and 6'' parallel with each other are formed in the chip, and, in the neighborhood of the end surface 2' of the chip, the two reflection mirrors 9 and 10 which have the inclination of 90 deg. to each other and make the inclination of 45 deg. between the longitudinal directions of the stripes 6' and 6'' are provided. Besides, the end surface 2' of the semiconductor laser chip is covered with a reflection prevention film 8. Therefore, the light generated in the stripe is reflected on the end surface 3' of the chip to some degree, but is hardly reflected on the end surface 2' and then radiated out of the chip. In this case, the sum of the lengths of the active regions in the resonator become twice the length 11 of the stripe 6' or the stripe 6''. Accordingly, the length 11' satisfies the condition of laser oscillation sufficiently by about 1/2 of the resonator length 11 of a conventional semiconductor laser. Consequently, the size of the chip can be reduced to about 1/2 of the conventional semiconductor laser.

Title: Liquid drop and drip preventing device having excellent appearance and function
Inventor: NAKAI YOSHIKAZU
IPC: B60R13/07
Filed: 1992-07-03
Abstract: PURPOSE: To improve the appearance and function of a device by a method wherein before liquid sags under its own weight in such a state that a surface tension is exerted on the liquid which is about to form in a spherical shape, the liquid is forcibly guided in a direction of a receiver. CONSTITUTION: When liquid flows down to the lower side along a side, most of the liquid forms liquid drips on the under surface. When a receiver 2 is installed at a stage followed by the drop of the liquid, the liquid flows to the receiver 2 as if it is sucked. When a quantity of liquid is high to some extent, an effect is produced in such a way that rounding is formed or a surface is formed at a spot where liquid 3 is rolled in. Further, by applying a negative pressure on the inner side of the support 2, a further effect is produced. In the embodiment of, for example, a spindle head 11 and a saddle 10 on the cross rail of a large machine tool, since, in most of machines, the spindle head 11 overhangs the saddle 10, lubrication oil is recovered by mounting a dripping and sagging preventing device on the spindle head 11 and the saddle 1.  As noted above, in a case of it being used in a machine, by mounting the receiver 2 during a machining work, even things of complicated shape can be simply manufactured and things of neat appearance can be inexpensively manufactured.

IPC: G03B13/14
Filed: 1988-08-30
Abstract: PURPOSE:To appropriately inform a photographer of the position of a close scenery correcting frame corresponding to focal length on any occation by eliminating finder parallax to be arised from a selected focal length in photographing a close scenery by means of changing a position in the finder of the close scenery correcting frame. CONSTITUTION:When the focal length of a photographing lens 1 is on a shorter side (wide side), a frame supporting member 6 is in the top left position, and the close scenery correcting frame 5a is also at the top left of a visual field frame 3. Afterwards, when the photographing lens 1 and a finder lens 2 move to the longer focal point (tele side) by the action of a zoom motor 9, the frame supporting member 6 moves to the right bottom together with the move of the lenses 1 and 2, and the correcting frame 5a also moves. When the focal length of the photographing lens 1 is between the longer and shorter focal points, the close scenery correcting frame 5a lies between them. As the focal length of the photographing lens 1 changes, the correcting frame 5a moves to the corresponding position. Thus, a photographer can realize the position of the close scenery correcting frame 5a corresponding to the arbitrarily set focal length, that is, a photographing range.
