Title: Device for measuring cross-polarization identifying degree
Inventor: HIGA MORIO
IPC: G01R29/10
Filed: 1980-04-15
Abstract: PURPOSE:To enable the symmetry of the rotation of antennas to be measured by rotating a polarization divider which is connected to the feeding point of the receiving antenna and the transmitting antenna in synchronization, with the axis of the receiving antenna as a rotating axis. CONSTITUTION:The output of a generator 1 which is radiated from the transmitting antenna 2 is received at both dividing paths of the polarization divider 4 via the receiving antenna 3. Both the transmitting antenna 2 and the polarization divider 4 are synchronously rotated by a rotating mechanism 6. At this time, the rotating mechanism 6 is sychronized by a rotation controller 5 so that one dividing path of the polarization divider 4 always receives positive polarization and the other dividing path always receive cross-polarization. The rotary angle signal and the output from the polarization divider are inputted to a recorder 8 via a signal transmitting path 9 and recorded. The cross-polarization identifying degree is obtained from the difference in receiving levels between the output from the positive polarization path and the output from the cross-polarization path. Thus, the mounting position of the primary radiator can be compensated when the specification of the cross-polarization identifying degree is strict.

Title: Reinforced concrete structure
Inventor: KAWAZU YUKITAKA
IPC: E04B1/16
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To absorb a deforming external force by an energy-absorbing member when the deforming external force is input in a structure at an earthquake. SOLUTION: Main columns 6 of the first floor of the basement of a reinforced concrete building 2 erected on the ground are made of concrete mixed with a polymer emulsion. And reinforced concrete studs 8 made of concrete without the polymer emulsion are arranged between the main columns 6 in the building. The studs 8 are made to have a lower strength and a higher rigidity than the main columns 6. When a large deforming external force is input in the structure in an large earthquake for instance, the deforming external force is absorbed by the plastic deformation thereof.

Title: Semiconductor device
Inventor: YAMASHITA HIROMITSU
IPC: H01L29/808
Filed: 1989-03-01
Abstract: PURPOSE:To improve mutual conductance to signal voltage by forming first and second semiconductor element formation areas of a semiconductor substrate of the first conductivity type such that the circumferences are surrounded by the first semiconductor layers of the second conductivity types. CONSTITUTION:A pnp bipolar transistor 30A and an n-channel JFET 30B are formed separately such that the circumferences are surrounded by an n<+> buried layer 21 and an n layer 22 being formed on a p-type substrate 1. Moreover, these n<+> buried layer 21 and n layer 22 are formed in a region which is surrounded by the p-type substrate 1 and isolating layers 2a and 2b. That is, the first and second semiconductor element formation areas are formed, with the circumferences being surrounded by the first semiconductor layers of the second conductivity types, on the semiconductor substrate of the first conductivity type, so those are in the conditions of being electrically isolated from the semiconductor substrate 1. Accordingly, desired signals can be supplied to semiconductor elements to be formed in the first and second semiconductor element formation areas, without exerting influence upon the substrate potential. Hereby, mutual inductance to control signals can be improved.

Title: High pressure fuse
Inventor: KUBOTA TOSHIHIKO
IPC: H01H85/175
Filed: 1995-03-09
Abstract: PURPOSE: To obtain a high pressure fuse which is small and light, and can be manufactured at a low cost. CONSTITUTION: A bobbin having numerous steps of insulation fins is formed by laminating flange form insulation rings 3 and insulation spacers 4 alternatively by using a center insulation rod 1 as the shaft, and fuse elements 5 are wound on the outer periphery. Terminals 2 are installed to both ends of the insulating rod 1, and the fuse elements 5 are connected to the terminals 2. On the inner peripheral surface of an insulating outer pipe 6 to house those members, also numerous steps of fins are formed by laminating flange form insulation rings 7 and insulation spacers 8 alternatively, and caps are placed on both ends of the insulation outer pipe 6.  By providing so many insulation fins between the terminals, a metal vapor is hardly attached to the deep parts of the insulation fins, even though the metal vapor is scattered when the elements 5 is melted, so as to leave numerous insulation areas. Consequently, the insulation between the terminals is maintained securely after the fusion of the fuse elements 5.

Title: Electrolyte film for solid high polymer fuel cell and its manufacture
Inventor: IIZAKA HIROFUMI
IPC: H01M8/02
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To enhance reacting capability by enlarging a contact area with a catalyst without lowering the performance as an electrolyte film. SOLUTION: A heavy metal substitutes for a proton by dipping a strong acid ion exchange membrane in an aqueous solution of weak acid salt of heavy metals such as lead, zinc and the like (process S10), a pattern by a hollow having a designated shape is formed by radiating radioactive rays such as an electron beam onto the surface of the ion exchange membrane the proton of which the heavy metal substitutes for (process S12), and the proton then substitutes for the heavy metal by dipping the ion exchange membrane the proton of which the heavy metal substitutes for in diluted sulfuric acid (process S14), to complete an electrolyte film. If radioactive ray is radiated onto a strong acid cation exchange membrane, decomposition of the ion exchange membrane is normally accelerated, however, the decomposition can be prevented by a heavy metal substituting for a proton.  As a result, an electrolyte film provided with a hollow having a designated shape can be manufactured without causing deterioration and destruction of an ion exchange membrane.
