Title: Demagnetizer of cassette-type magnetic head
Inventor: OKUDA TADANOBU
IPC: G11B5/465
Filed: 1980-08-30
Abstract: PURPOSE:To ensure an assured demagnetizing action, by actuating a demagnetizing switch with the change of tension of a belt-shaped matter which is provided a pinch roller and a capstan of a tape recorder within a cassette case. CONSTITUTION:When a head 9 goes into a head inserting window 4 of a cassette case 1 and then presses a demagnetizing electromagnet 6, the magnet 6 goes back against the spring force and touches close the head 9 via a front nonmagnetic cover 9. When a tape recorder is set in the resording/reproduction mode, a pinch roller 20 and a capstan 21 give the rotary drive to a beld-shaped matter 19. Thus a part 19a between the rotary contact point and the detaining point of the matter 19 turns gradually into a state of strain. As a result, a working lever 24 of a switch 23 is operated to close the switch 23, and then a demagnetizing circut 12 works. The switch 23 can also be actuated by making use of a state of relaxation in place of a state of strain of the matter 19.

Title: Keyboard device
Inventor: MORI SHINICHI
IPC: H03M11/14
Filed: 1987-05-18
Abstract: PURPOSE:To clearly discriminate the characters and symbols shown on key tops by applying illumination to those characters and symbols corresponding to the modes selected by the key tops respectively. CONSTITUTION:Four characters/symbols 3a-3h are displayed on a single key top 2 and also correspond to four different modes. At the same time, four illumination light transmitting parts 4 are added onto the key top 2 for display of said characters/symbols 3a-3h respectively. These parts 4 are connected to the corresponding light sources 6a-6d via optical fibers 5. The light sources 6 are used in number corresponding to the number of types of modes. Then the sources 6 are selected with operation of a mode changeover key 7 via a switch changeover part. Thus only those characters/symbols corresponding to the relevant modes are illuminated. As a result, a specific mode used for the relevant symbol on the top 2 can be simply confirmed.

IPC: E21D9/06
Filed: 1989-05-15
Abstract: PURPOSE:To prevent occurrence of troubles due to a useless pipe line even in the future by excavating vertical shafts in the underground buried pipe line and removing a pipe, inserting a conical type grinding machine in one of the vertical shafts and filling a filling material in the cavity of the original pipe line after having the grinding machine reach the other one of the vertical shaft crushing the pipe and lifting it up.

After a filling material 6 is injected in a cavity 5 of the pipe line, the vertical shafts 1A and 1B at the two points are backfilled. Consequently, even if the pipe line is curved, it is possible to extinguish it well. Additionally, the buried pipe is turned to be in the state of not being a rigid structural body, it is not an obstruction for construction.

Title: Manufacture of stainless chain
Inventor: KUROMATSU TOKUMITSU
IPC: B23K11/04
Filed: 1978-09-29
Abstract: PURPOSE: To increase the strength of a chain by preventing oxidation of a juncture surface part and precipitation of chromium carbide by superposing a high-frequency current by covering the juncture surface part with inert gas during fusion and deposition of the juncture flank of a chain member.  
     CONSTITUTION: Chain member A is supported electrodes 1 and 2 at both its sides and a high-frequency current is fed to minus electrode 2. Inert gas of argon, etc., is jetted from gas nozzle 3 and the outer circumference of juncture flank (a) is covered with it. Next, electrodes 1 and 2 are set mutually closer to put juncture flanks (a) in pressure contact and a direct current is fed from plus electrode 1 to minus electrode 2 to fuse juncture flanks (a) in an upset process, thereby forming those structures in one. This method prevents oxygen from combining with the juncture surface part and also shorten a feeding time until a needed heating temperature, thereby suppressing partially the intergranular precipitation of chromium carbide.

Title: Membrane system
Inventor: DEIBITSUDO EMU ANDASON
IPC: H01M50/417
Filed: 1988-05-20
Abstract: A new type of polymeric microporous membrane has been synthesized which is distinguished by a highly-branched porespace morphology that is continuous and triply-periodic, and thus very precisely controlled and easily characterized. The membrane consists of a polymeric matrix containing pores of diameter on the order of 10 nm connected into a continuous pore network exhibiting long-range three-dimensional order. This long-range order is evidenced in small-angle X-ray scattering (SAXS) experiments by Bragg reflections that index to a triply-periodic space group, as well as in electron micrographs that match predictions from a theoretical model of the same space group and lattice parameter. The membrane combines three important features that have not been present simultaneously in any prior art membrane having pore diameters between 2 nm and 1 micron. First, the pores are identical in size and shape to a very high degree, and their size can be controlled in the synthesis. Second, the porespace is characterized by intricate branching and reconnections, with at least three pore throats meeting at a given pore body, this number (the coordination number) being the same for each pore body, and the porespace is isotropic in the cases where the space group is cubic. These two features allow accurately controlled sieving on the basis of particle size and shape, and provide highly accessible and precisely shaped pore bodies and surfaces for other applications such as catalysis, ion exchange, and the preparation of metal microstructures. And third, the membrane has a high porosity -- approximately 90% -- so that high rates of throughput can be reached. In addition, the membrane can be produced from certain microstructured fluid phases that are thermodynamic equilibrium states, so that it can be produced inexpensively and reliably.
