Title: Lateral stabilizing device for small water plane single hull ship
Inventor: YOSHIMURA YASUO
IPC: B63B43/14
Filed: 1988-10-05
Abstract: PURPOSE:To improve lateral stability of a ship hull during low speed sailing and a stop as intrinsic high speed performance is ensured in an excellent state in a way that inclination of the ship hull during low speed sailing and a stop is supported by a method wherein a pair of elevation type floating bodies on both sides are mounted to both side of the ship hull. CONSTITUTION:In a small water plane single hull ship (SWASH) 1, since a water plane is small and narrow, ship hull resistance is low and high speed performance is excellent, and on the other hand, lateral stability during low speed sailing and a stop is deteriorated. In this case, a pair of floating bodies 2 on both sides are elevatably mounted to both sides of the ship hull of the SWASH 1 through a pair of mounting bodies 3 on both sides. Each floating is formed in the same shape in cross section as that of a water surface gliding type, e.g. motor boat, so that high resistance is prevented from being exerted during transfer to high speed from low speed sailing. This constitution supports inclination of the ship hull by lowering each floating body 2 during low speed sailing and the stop of the SWASH 1, and improves lateral stability of the ship hull.

Title: Pattern formation
Inventor: KUMADA TERUHIKO
IPC: G03F7/38
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a pattern forming method by which a pattern having high dimensional accuracy can be obtained without receiving any influence from the variation of the elapsed time of processes. SOLUTION: A pattern forming method includes a step of forming a resist film on a substrate (S1), a step of infiltrating water into the resist film (S3), and a step of performing exposure treatment for transferring a pattern to the resist film infiltrated with the water. Since the resist film can be infiltrated with water, the influence to the catalytic reaction of the acid contained in the resist film can be prevented by the water absorbed into the resist film from the atmospheric gas in such a case that the elapsed time of processes from the formation of the resist film to the exposure treatment vary. Consequently, a resist pattern having high dimensional accuracy can be obtained.

Abstract: PROBLEM TO BE SOLVED: To completely eliminate the influence of a burr to the degree of flatness of an optical disk formed by sticking substrates together by providing a dummy substrate side stuck surface with a ruggedness avoiding part which avoids ruggedness on the information recording substrate side stuck surface. SOLUTION: Recessed parts 25, 24, 21 of a ruggedness avoiding part are provided at a position on a stuck surface S2 of a dummy substrate 20 corresponding to the burr position formed in the stuck surface S1 of a substrate 60. Also, a burr B4 projects in a direction parallel to the stuck surface S2 by providing the recessed part 25 in the dummy substrate 20. And, since the depth of the recessed part 21 is designed so as to satisfactorily become deeper than the size of a burr B6, the burr B6 never projects from the opening surface of the recessed part 21. Thus, burr interference with stuck surfaces S1, S2 between the substrate 60 and the dummy substrate 20 is eliminated.

Filed: 1994-09-20
Abstract: PURPOSE: To ensure a monotonous input output characteristic by using two current mirror circuits thereby supplying a base current of two Wilson type current mirror circuits. CONSTITUTION: Even when an input voltage applied to an inverting input terminal 4 is considerably lower to a voltage to a noninverting input terminal 3 and a collector current of a transistor(TR) Q4 is I and a collector current of a TR Q2 is zero, a 2nd current mirror circuit 11 is operated normally.

Filed: 1994-09-21
Abstract: PURPOSE: To improve the frequency response of radio-frequency operation, by effectively shortening a current path passing a resistor and performing the physical layout, which can perform the effective current distribution. CONSTITUTION: In a thin-film resistor 100, a first electrode 101, a second electrode 102, and a resistor material 103 for the electrically connecting first and second electrodes are included.

IPC: H01S5/40
Filed: 1986-10-24
Abstract: PURPOSE:To enable a laser array to be manufactured with good reproducibility by providing dummy channels which do not become a semiconductor laser beam emitting section on both sides of the channels, thereby making uniform the thickness of each resonator and the characteristics of the laser beam emitted from each resonator. CONSTITUTION:On the principal surface of the substrate 2 of a semiconductor laser device 12, three channels 1 shaped in a reverse trapezoid is provided in parallel with each other, on both sides of which dummy channels 11 are provided. In the manufacture of the semiconductor laser device 12, a step easily develops in the parts of a lowermost clad 3 corresponding to the corners of each groove, but, since the distance between the respective grooves is several mum to several tens of mum, namely close to each other, a step develops only in the parts corresponding to the outer corners of dummy channels 8 and the surface of the clad layer 3 becomes a planar surface in the other channels 1 parts. As a result, the thickness of an active layer 4 corresponding to the three channels 1 parts dedicated to a laser array does not vary, becoming a homogeneous and uniform thickness. Therefore, the light emitting characteristics in each resonator 7 becomes uniform and stable.

Abstract: PROBLEM TO BE SOLVED: To obtain such a laminated body that a three-dimensional hologram layer is surely broken and that forgery can be surely prevented, by successively laminating an adhesive layer, three-dimensional hologram layer, resin layer containing monomers or plasticizer, and surface protective film on a base body. SOLUTION: This three-dimensional hologram laminated body contains a picture of a face 4 adhered with a photographic adhesive 3 to a base body 2. Then an adhesive layer 5, three-dimensional hologram layer 6, resin layer 7 containing monomers or plasticizer, and surface protective film 8 are successively laminated to cover both of the base body 2 and the picture 4. When the three-dimensional hologram laminated body is to be peeled, the surface protective film 8 or the laminated structure of the surface protective film 8 and the resin layer 7 containing monomers or plasticizer is peeled from the three-dimensional hologram layer 6, while the three-dimensional hologram layer 6 remains on the picture. Because the three-dimensional hologram layer 6 is brittle, the three-dimensional hologram layer 6 is surely broken when it is peeled from the picture 4.
