Title: Rope-winder used in trawlboat
Inventor: FUJIMOTO TADASU
IPC: B65H54/28
Filed: 1989-11-24
Abstract: PURPOSE:To reduce the size of a winding reel, lower the installation position of a winder and improve the stability of a trawlboat by placing a shifter shaft at the rope-drawing side of a winder parallel to a winding reel and connecting the shifter shaft to a driving source of the winding reel via a speed-changeover means. CONSTITUTION:The rotational speed of a shifter shaft 21 of a rope-shifting mechanism 20 is changed by a speed-changeover means 31 of a shifter driving mechanism 30. In the case of winding a rope having the smallest diameter onto a winding reel 13 of a winder main body 10, a rope shifter 23 is driven at a speed corresponding to the diameter of the rope to wind the rope having the smallest diameter onto the winding reel without leaving a gap. The rope shifter is driven at a higher speed for winding a rope having larger diameter. Any kind of rope can be wound in flat and closely contacting state to decrease the winding diameter and shorten the width of the wound rope in the direction of winder shaft.

Filed: 1992-10-20
Abstract: PURPOSE:To generate large frictional force with a rail by fixing magnets rigidly to yokes fitted in plural positions on a magnet belt, and providing a frame part, formed of friction material, around each yoke. CONSTITUTION:Plural yokes 6 are fitted at specified spaces apart onto a magnet belt 3, and a magnet 7 is rigidly fixed onto each yoke 6 by adhesive or the like. A frame part 9 is further provided around the yoke 6, and this frame part 9 is fixed to the magnet belt 3 by binding material, screws, or the like. The frame part 9 is formed of friction material with a large friction coefficient, and the frame part 9 obtains pressure by the attracting force of the yoke 6 with the magnet 7 fixed thereto so as to generate large frictional force with a rail. This results in obtaining about double frictional force or more compared to the case of fitting only the yokes 6 to the magnet belt 3.

Abstract: PURPOSE: To eliminate irregularities on an image while light is prevented from being leaked to a photoreceptor by providing a transfer belt with a marker for detecting the resistance of a transfer belt in a circumferential direction and controlling the output of an electric charge supply means based on the detected result. CONSTITUTION: The marker 19 formed by boring the transfer belt 6 is formed at a part of the belt 6.

On the other hand, since the belt 6 is bored at the part of the marker 19, the signal of the light emission part 20 arrives at the light receiving part 21 so that the existence of the marker 19 can be detected.  Then, the output of the detection device 18 is inputted to a control panel controlling the output of the electric charge supply means.

IPC: H01L21/205
Filed: 1987-12-07
Abstract: PURPOSE:To limit an oscillating part to a extremely narrow region so as not only to ensure an excellent property but also simplify a process by a method wherein a stripe-like groove is formed onto the surface of a semiconductor substrate and laser rays are irradiated onto the groove so as to enable a clad layer on the groove to thicker than a clad layer on the other region. CONSTITUTION:An n-type GaAs substrate 1 is provided and a stripe-like pattern mask is formed on one of its primary faces at a required pitch. And, the substrate 1 is etched making use of this mask. Next, a double hetero structure is formed on the n-type GaAs substrate 1 provided with the stripe-like groove through a laser ray irradiation. Next, laser rays are irradiated only onto the stripe-like groove region formed on the surface of the n-type GaAs substrate 1 and the region irradiated by laser rays 3 is made to be higher than the other region in a growth rate and impurity density. By these processes, an n- Ga1-xAl1-xAs layer 2 of a flat n-type clad layer with an epitaxial surface is formed, and a clad layer containing impurity high in concentration is formed on a region above the groove. Therefore, a current is efficiently restrained from spreading, so that a laser emitting section can be limited to an extremely narrow region.

Filed: 1990-11-15
Abstract: PURPOSE:To obtain a low threshold current value whose carrier overflow is below the limit of a material by a method wherein carrier-confining layers composed of p-type AlGaInP and n-type AlGaInP are formed between an active layer, a p-type light-confining clad layer and an n-type light-confining clad layer. CONSTITUTION:An n-type AlGaInP light-confining clad layer 2, an AlGaInP active layer 3, a p-type AlGaInP carrier-confining layer 10 (thickness: 5nm) and a p-type AlGaInP light-confining clad layer 4 and the like are formed sequentially on an n-type GaAs substrate 1. The layer 10 having a thickness of 5nm or more is formed between the layer 3 and a layer 4 and a carrier- confining layer 11 whose lattice is shorter than that of GaAs, whose thickness is 5nm or more and which is composed of n-type AlGaInP is formed between the layer 3 and the layer 2. Thereby, it is possible to restrain not only the overflow of electrons but also the overflow of holes which appear when the energy gap of the layer 3 is made large. Since the distribution of a refractive index becomes symmetric with respect to the layer 3, light is distributed around the layer 3, an optical intensity becomes stronger at the layer 3 and a threshold current value can further be reduce.
