IPC: H04L9/08
Filed: 1998-05-21
Abstract: A method is provided for an escrow cryptosystem that is overhead-free, does not require a cryptographic tamper-proof hardware implementation (i. e., can be done in software), is publicly verifiable, and cannot be used subliminally to enable a shadow public key system. A shadow public key system is an unescrowed public key system that is publicly displayed in a covert fashion. The keys generated by the method are auto-recoverable and auto-certifiable (abbrev. ARC). The ARC Cryptosystem is based on a key generation mechanism that outputs a public/private key pair, and a certificate of proof that the key was generated according to the algorithm. Each generated public/private key pair can be verified efficient ly to be escrowed properly by anyone. The verification procedure does not use the private key. Hence, the general public has an efficient way of making sure that any given individual's private key is escrowed properly, and the trusted authorities will be able to access the private key if needed. Since the verification can be performed by anyone, there is no need for a special trusted entity, known in the art as a "trusted third party". The cryptosystem is overhead free since there is no additional protocol interact ion between the user who generates his or her own key, and the certification authority or the escrow authorities, in comparison to what is required to submit the public key itself in regular certified public key systems. Furthermore, the system is designed so that its internals can be made publicly scrutinizable (e.g., it can be distributed in source code form). This differs from any schemes which require that the escrowing device be tamper-proof hardware.

Abstract: PURPOSE: A device for manufacturing a deodorant using a weathered coral for use in a place where a dynamic external force such as a frictional force or the like exists is provided to continuously remove the odor of the body generated from sports shoes, sports wears or the like. CONSTITUTION: Weathered coral gravel(1) is heated and sterilized by a heating sterilization means(2) and crushed by a fine crushing means(3). The weathered coral gravel(1) may be baked by a baking means instead of the heating sterilization process. This sequence of heating and sterilization(or baking) and crushing may be reversed. The manufactured coral deodorant(4) is made into a fine granular agent(4a), and in the case of use in shoes or the like, moisture such as sweating or the like is obtained so that it may be used as it is. In the case of use in things without moisture, the fine granular agent(4a) is mixed with water in a receiving means(5) to be made into a liquid formulation(4b). Thus, when moisture adsorbed to a pore structure is subjected to external force, moisture generates radical negative ions by interaction with calcium carbonate in coral fine grains, so that oxidized moisture is alkalified to decompose odor component and lipid from the surface active action of the negative ions, thereby removing odor.

Abstract: PURPOSE: A pulse tube refrigerator is provided to simplify the structure of a pulse tube refrigerator as well as to minimize the vibration while running the pulse tube refrigerator. CONSTITUTION: High-temperature high-pressure working gas flows into a pulse tube(20) with keeping sensible heat through a regenerator(50) when the working gas is pumped out by a pump(100). The working gas is compressed in the pulse tube and supplied to a storage container(150) through a capillary tube(160). The working gas is adiabatically expanded through the capillary tube, and the temperature rises up. The working gas is expanded in the capillary tube to fill the storage container. When the pump sucks the working gas, the gas flows out of the pulse tube. The working gas is expanded in the pulse tube and, the heat is absorbed into an expander(22). The expander obtains the cryogenic state by repeating the series of processes of absorbing the heat of the working gas. A linear motor(120) in the pump generates the rectilinear reciprocating power. The power is transferred to a piston(140) to pump the working gas with the piston rectilinearly reciprocating in a cylinder(130). In the process, vibration is generated and transferred to a hermetic case(110). The vibration is transferred to a vibration absorbing unit(170) connected to the hermetic case. Therefore, the vibration absorbing unit is run to offset the vibration of the hermetic case.

Abstract: PURPOSE: Both radial piston pump and motor of static pressure bearing structure is provided to obtain the maximum output torque by rotating a shaft with hydraulic pressure and to enhance the efficiency by reducing friction. CONSTITUTION: A static pressure bearing is a bearing for supporting a load with hydraulic pressure generated in a pocket when high-pressure fluid is supplied into the pocket covered by a land. The load is supported by all of the hydraulic pressure, and a friction coefficient is reduced. In case of general bearings such as a ball bearing and a roller bearing, an oil film is not formed if the general bearing does not obtain specific RPM(Revolutions Per Minute). Thereby, friction is increased and the start performance of a hydraulic motor is reduced. The general bearing disturbs the smooth operation of the hydraulic motor. However, the static pressure bearing generates the force for supporting the load depending on the contact speed. Therefore, the static pressure bearing obtains the smooth operation and promotes stability therefrom.
