Title: Waveguide type phase shifter
Inventor: YONEKURA MASAMICHI
IPC: H01P1/195
Filed: 1982-10-26
Abstract: PURPOSE:To suppress the generation of loss increased at a specific frequency by mounting a member having a large loss at a passing microwave frequency around a conductor flowing a current for magnetizing a ferrimagnetic substance and near a waveguide inner wall. CONSTITUTION:The ferrimagnetic substance 2 in contact with an up and down wall of the waveguide 1 is provided with a hole 3 penetrated with a conductor 4. A troid core 5 having a material property different from that of the ferrimagnetic substance 2 forming a phase shift element and made of a ferrimagnetic substance having a loss larger at the operating frequency of the phase shifter is covered onto the conductor 4 and mounted on the side wall of the waveguide 1. Thus, the core 5 made of a material having a large magnetic loss is covered onto the conductor 4, the Q of a closed loop constituting the inner walls of the waveguide 1 and the conductor 4 is decreased, and the generation of spurious harmonic mode is suppressed. Further, the loss to the basic mode is not increased. Then, the generation of loss increased in spike at a specific frequency is pressed.

Abstract: PURPOSE:To ensure the security of a high level by varying a condition for permitting to set newly a key into a file for service offerer in accordance with whether a service offerer key is set already or not. CONSTITUTION:A service offerer key 14 can be written unconditionally, or after collating an issuer key 12 written already in a common file 11, and after the service offerer key 14 is written, the service offerer key 14 becomes necessary in order to execute an access to a separate file 13. Accordingly, by setting or updating the service offerer key 14 to a value which only a service offerer knows, even an issuer is inhibited from executing an access to the separate file 13. In such a way, the security of a high level can be ensured.

Abstract: PROBLEM TO BE SOLVED: To facilitate length adjustment, and prevent adhesion from being decreased and stress from being applied in winding and fitting work by plane- forming a plurality of heating wires with elasticity side by side, which are bent to be a wave form, and forming expandably contractibly with the heating wires jointed to each other. SOLUTION: A heating wire with elasticity is obtained by winding a nichrome wire around a core material made of glass fiber or the like, and coating its circumference with an envelope, such as vinyl chloride. This heating wire 56 is bent into a wave form, such as a sinewave. By folding the bent heating wire 56 three times at its halfway part, the first reciprocating parts 56a, 56b and the second reciprocating parts 56c, 56d are formed, and by separating them from each other, they are plane-formed in parallel in the identical direction. At the most adjacent bent part, the heating wires are jointed to each other by a joint material 12 with flexibility, made of synthetic resin or the like, so as to be a mesh body as a whole. By jointing the folded part A and the folding start and finish portions of the heating wire 56 integrally with jointing members 14, 16 made of synthetic resin, and connecting a power supply cord 60, it is possible to obtain an antifreezer 10.

The outside diameter thereof is in a range of 1 to 0.3mm in order to be inserted into the fine peripheral blood vessel. The thickness of the tube wall is in a range of 0.2 to 0.05mm. The internal cavity of the catheter is larger as this thickness is smaller insofar as the necessary strength as the catheter is maintainable. The improved operability of a guiding wire and an increased amt. of the liquid to be injected are then resulted and, therefore, this range is more preferable.  The pressure resistance strength of the shaft 2 is not particularly restricted, insofar as the shaft withstands the pressure at the time of injection of a contrast medium, therapeutic medicines, closing material, etc.

Title: Electrolytic method
Inventor: NISHIKI YOSHINORI
IPC: C25B1/16
Filed: 1995-06-30
Abstract: PURPOSE: To stably perform electrolysis of brine at a low cost and low overvoltage by supplying oxygen-enriched air that is obtained by treating air with an adsorbent to a cathode chamber provided with a gas diffusion cathode and feeding brine to an anode chamber. CONSTITUTION: In this method, electrolysis of brine is performed while supplying an oxygen containing gas to a cathode chamber provided with a gas diffusion cathode and concurrently feeding the brine to an anode chamber to produce a caustic soda aq. solution in the cathode chamber and chlorine in the anode chamber. At this time, as the oxygen containing gas, oxygen-enriched air that contains about 90% oxygen and is obtained by treating air with an adsorbent capable of selectively adsorbing nitrogen in the presence of oxygen, is used. As this adsorbent, a zeolite capable of efficiently adsorbing and desorbing nitrogen by elevating and lowering the pressure at a low temp. and further, of adsorbing and removing gaseous carbon dioxide in air is preferred.  Thus, with the oxygen-enriched air, the electrolysis of brine can efficiently be performed at a low overvoltage almost equal to that at the time of performing the electrolysis with pure oxygen and also, the formation of a sodium carbonate precipitate and therefore, blocking of a diffusion layer can be prevented from occurring.

While the improvement of this regidity eliminates the necessity for forming a conventional rugged bead part or the like in the seat surface part 6a. Accordingly, a cushion material can be directly mounted through no seat frame, and a low seating position of passengers is attained from point of lowering the upper surface position of a cushion and forming the seat surface part 6a being recessed to the bottom, thus a head clearance can be ensured by that amount of the lower seating position of the passengers.
