Title: Metallic fish preserve for breeding
Inventor: TAKATORI HIDEO
IPC: A01K63/00
Filed: 1995-03-03
Abstract: PURPOSE: To prolong the life time of metal screen for fish preserve by solving the problems on screen abrasion. CONSTITUTION: In the metal screen 1 for fish breeding which is given by knitting metallic wires so as to form meshes, the number of the meshes at the middle part of the screen is reduced compared with the numbers of the meshes of the upper and lower parts. In this case, it is recommended that the metallic wire is made of titanium or a titanium alloy. The tension caused by the weight of the mesh inclines from the vertical direction to produce a horizontal component force and give the screen a horizontal tension. As a result, the screen is prevented from bending whereby the relative motions between the wires are suppressed to reduce wire abrasion.

Title: Image forming device
Inventor: OWADA MITSURU
IPC: B41J2/44
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to stabilize an output image and improve image quality without affecting image formation and without causing color slippage, even in the case of the occurrence of error such as fluctuation in scanning speed by generating photoreceptive parts and non-photoreceptive parts onto the surface of an image carrier by the use of a discrete latent image forming means, and forming a latent image discretely. SOLUTION: A conventional photoreceptor drum has uniform photoreceptive characteristics over the entire surface of the drum. However, in this device, the photoreceptive characteristics are minutely separated. That is, light interception parts 103 and open parts 104 are formed on the uniform surface layer of the photoreceptor 102. Thus, a laser beam 105 as an exposure light is intercepted by the light interception part 103 and does not reach the photoreceptor 102, and in the open part 104 it is emitted to the photoreceptor 102 as it is. Therefore, the photoreceptor drum has the characteristic in which its surface is masked by the light interception part 103. This means that an image to be outputted is discretely sampled on the surface. The minutely discrete potentials on this entire surface are subjected to development by a developing device and to transfer and fixing to paper.

Title: Semiconductor laser
Inventor: MURAKAMI TAKASHI
IPC: H01S5/00
Filed: 1987-03-23
Abstract: PURPOSE:To make it possible to oscillate laser at a low threshold value without increasing a leakage current, by forming a second-conductivity type second current blocking layer, which forms an inverted mesa shape on both sides of a stripe shaped groove, on a first current blocking layer. CONSTITUTION:A positive voltage is applied on a P-side electrode 9, and a negative voltage is applied on an N-side electrode. Then a current flows through a groove 10. A second clad layer 4, an active layer 5 and a third clad layer 6 form a double heterostructure. When carriers are injected into a part in a groove 10a in the active layer 5, light is emitted and laser is oscillated. A second current blocking layer 3b, which has an inverted mesa shaped part 13, is formed on a first current blocking layer 3b. Therefore, a gap 11 becomes narrow, and a leakage current is hard to flow. Therefore, the most of the current is concentrated in the active layer 5 in the stripe shaped groove 10a effectively.

Abstract: PURPOSE:To obtain a control system to quickly respond and not to overshoot by linearly changing the gain of the control system according to the quantity of a deviation. CONSTITUTION:When a set gain is made into G and a deviation signal is made into epsilon, for the gain of a digital controller equipped with an absolute value converter 8 and a gain arithmetic device 9, the deviation signal is made into ¦epsilon¦by the absolute value converter 8, the gain computing element 9 function- converts the output value of the absolute value converter 8 to 1+DELTA, and GX(1+DELTA) is obtained with the set gain G.
