Title: Radio wave absorber
Inventor: KOZUKA YOJI
IPC: H05K9/00
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To make a radio wave absorbing material matched even when it shows no matched properties by providing vacant holes in the surface of the radio wave absorbing material showing no matched characteristics in a desired frequency band. SOLUTION: A radio wave absorber is prepared by providing cross-shaped vacant holes 2 in a radio wave absorbing material 1 which can not be matched, irrespective of the thickness and by backing the material with a back conductor plate 3. Thereby matching can be attained. By regulating the thickness of rubber ferrite of the radio wave absorbing material 1, the dimensions of the vacant holes, the shape etc., for instance, the matching can be attained for a wide band of 0.8-5GHz. Since the attainment of the matching for the wide band is attained by a single material in this way, it becomes unnecessary to search for a fresh radio wave absorbing material or to manufacture the fresh material under complicated conditions. When a desired frequency band is once determined, besides, optimum distribution of the vacant holes can be determined easily by computer simulation.

Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide an underwater sound simulator which has simple structure, is easy to change conditions, has larger simulated range for underwater sound, and is inexpensive. SOLUTION: A sound source model 11 simulates underwater sound wave generated by a real underwater sound source, and outputs a simulated sound wave signal U, that is an electric signal whose characteristic is changed according to sound characteristic of the sound source. An underwater propagation model 12, which has electric propagation characteristic which, is simulation of sound propagation characteristic in real water, alters characteristic of the simulated sound wave signal U according to the electric propagation characteristic and outputs a simulated signal V.

Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a multiple quantum well structure caused by the unstableness of barrier layers by successively alternately laminating InGaAs well layers having compressive-strains and the barrier layers having compressive strains and composed of InGaAsP or InGaAs upon another on an InP substrate. SOLUTION: A compressive-strain quantum well structure 2 composed of well layers 3 and barrier layers 4 is constructed on a substrate 1 composed of a single semiconductor crystal. The well layers 3 and barrier layers 4 are alternately laminated upon another and carriers are enclosed in the well layers 3. Compressive strains εW and εb are respectively applied to the well layers 3 and barrier layers 4. The well layers 3 are made of InGaAs and the compressive strains applied to the layers 3 and the thicknesses of the layers 3 are respectively adjusted to, for example, 1.6% and 120Å. The barrier layers 4 are made of InGaAs and the thicknesses of the layers 4 are adjusted to, for example, 200Å. In addition, the number of the well layers 3 is adjusted to, for example, two.  Therefore, the breakage of the multiple quantum well structure caused by the unstableness of the barrier layers can be prevented by reducing the strain discrepancy between the well layers and barrier layers.

Title: Top sealer for paper container
Inventor: YAMASHITA NOBORU
IPC: B65B7/16
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent a foreign matter from being mixed with a simple structure and facilitate cleaning by driving, via a rotation member lever, a paper container top seal placed above by a cylinder placed below. SOLUTION: When a connection lever (b) is lowered to the lowest position by a cylinder (a), a circular rotation driving board (c) rotates clockwise. Thus a surface lever (d) moves to right, and a rear lever (d) moves to left, respectively. Thus rotation members (e), (e) rotate toward a closed direction with an axis 9 as the center, thereby tightening a top of a paper container (g) by seal blocks (f), (f). When sealing is completed, the cylinder (a) is used to push up the connection lever (b). Thus the levers (d), (d) move reversely, so that the tips of the rotation members (e), (e) open with the axis 9 as the center, to have the sealed paper container (g) opened. Since the seal blocks (f), (f) are shifted aside from above the cylinder (a), entrance of dust or the like from above the cylinder (a) can be prevented.  In addition, a space above the rotation member (e) becomes empty, thereby preventing a foreign matter from dropping, and cleaning is easy.

Title: Relief valve
Inventor: KAKU BOUOU
IPC: F16K17/04
Filed: 1992-11-30
Abstract: PURPOSE:To reduce the quantity of parts, and realize a compact design via the simplification of a structure by providing a communication tube having a larger inner diameter at the side of a poppet than at the side of a piston, and a spring or the like for pressing a piston toward a back chamber and the poppet toward a seat. CONSTITUTION:When the pressure P1 of a primary side passage (a) becomes higher than the pressure P2 of a secondary side passage (b), oil in the primary side passage (a) enters a back chamber 8 via a diaphragm 12, a through-hole 11 and a hole 9. Also, a communication tube 4 moves upward due to a difference in the cross sectional area thereof. Furthermore, as differential pressure occurs in a poppet 3 before and after the diaphragm 12, due to the travel of the tube 4, the poppet 3 follows the motion of the tube 4. As a result, the primary and secondary side passages (a) and (b) become communicated with each other. On the other hand, the pressure of the back chamber 8 increases according to the rise of the pressure P1 and, therefore, a piston 6 moves downward against the force of a spring 5. Also, the force of the spring 5 rises according to the travel of the piston 6, and the deflection of the spring 5 increases, until the tube 4 comes in contact with the piston 6 and the piston 6 with a body 1.
