Title: Data encryption system, information processing unit, ic card, recording medium and encryption method for data
Inventor: ARAI MASATO
IPC: G09C1/00
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To relieve the load on the users in an encryption system for electronic mails. SOLUTION: In the case of transmitting a mail, an IC card 15 generates a group key based on a master key 152d and a destination list of the mail. Upon receipt of the group key, a client information processing unit 12 encrypts the electronic mail with an effective key and encrypts the effective key by the group key. Then the header of the encrypted mail to which the encrypted effective key and the destination list are added is transmitted. On the other hand, in the case of receiving the encrypted mail, the IC card 15 discriminates whether or not the destination list added to the encrypted mail includes the card 15 itself and generates the group key based on the destination list and the master key 152d. Then the encrypted effective key added to the encrypted mail is decoded by using the generated group key and the encrypted mail is decoded by using the effective key.

Title: Ceramic composition having high dielectric constant
Inventor: SAWAMURA KENTARO
IPC: C04B35/46
Filed: 1988-06-27
Abstract: PURPOSE:To enable the maintenance of high resistance even by calcining in an atmosphere under a low partial pressure of oxygen by substituting Mg for part of Nb or Ti in compound perovskite represented by a formula Pb(Ni1/3 Nb2/3)O3-PbTiO3 so as to obtain a specified compsn. CONSTITUTION:This ceramic compsn. having a high dielectric constant is represented by the general formula (where 0.95<=a<=1.2, 0.005<=b<=0.4, 0.4<=x<=0.8 and x+y=1). It is supposed that the conversion of this compsn. into an n-type semiconductor is inhibited because divalent Mg atoms are substd. for part of pentavalent Nb atoms or tetravalent Ti atoms in the B site component and excess electrons generated by the release of oxygen during calcining are captured by the difference in valence.

Title: Collection of fine particle
Inventor: SUGATA MASAO
IPC: B01J19/08
Filed: 1986-07-08
Abstract: PURPOSE:To selectively form and collect objective fine particles, by forming fine particles into a beam stream and receiving said beam stream by a substrate while moving said substrate. CONSTITUTION:When fine particles are supplied into an upstream chamber 3, while a downstream chamber 4 is evacuated, the fine particles flow through a contracting and expanding nozzle 2 from the upstream chamber 3 to flow in the downstream chamber 4. The contracting and expanding nozzle 2 can inject fine particles as a proper expanding stream of ultrasonic velocity by regulating the pressure ratio of the upstream chamber 3 and the downstream chamber 4 corresponding to the opening area ratio of a throat part 2b and an outflow port 2c. When the fine particles are injected in a definite direction by this method, the fine particles straightly advance to be formed into beam while the cross-section of the jet stream immediately after injection is held. Therefore, when the fine particles are activated in the contracting and expanding nozzle 2 to be transferred in a beam form, said fine particles are transferred as beam spatially held to an independent state at ultrasonic velocity and can be adhered to and collected by a substrate 1. The substrate 1 is moved corresponding to the time required in forming an objective product to collect said objective product.

Title: Magnetic head supporting mechanism
Inventor: ITO KEIICHI
IPC: G11B21/21
Filed: 1988-06-27
Abstract: PURPOSE:To enable discrepancies among sliders in pressure balance due to different kinds to be adjusted with the shape of a load spring by welding a gimbal spring to bifurcate roots of the load spring and bonding the slider to the tip of the gimbal spring. CONSTITUTION:The slider 1 is bonded to the tip part of the gimbal spring 2, and the gimbal spring 2 is welded to the bifurcate root parts at the tip of the load spring. The tip of the load spring is bifurcated with spring properties to be extended to embossed parts 3 provided on the gimbal spring 2. In other words, when a medium is pressed by the load spring 4 with the opposite surface of the slider to the medium via the gimbal spring 2 and the embossed parts 3 at a prescribed pressure, one embossed part 3 of the gimbal spring 2 is pressed by one of the bifurcate tip parts of the load spring 4, while the other embossed part 3 of the spring 2 is pressed by the other tip part of the spring 4. Consequently, the strength of each spring property for the two tip parts of the spring 4 respectively can be adjusted by altering the width sizes A and B.

Abstract: PURPOSE:To prevent oxidation of a parts holder due to heating so as to achieve long life by forming the parts holder for holding glass parts out of silicon based materials. CONSTITUTION:A bridge glass holder 11 for holding glass parts 5a is formed out of silicon materials such as silicon nitride or ceramic. Since the holder if is not oxidated when it is heated, oxides will not be contained in a bulb of a halogen bulb, and the life of the lamp is thus elongated.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To provide information having a meaning in combination with a reversible display and a print display by sequentially laminating a release protective layer, a print display layer, a thermal recording layer, an intermediate layer, a coloring layer and an adhesive layer on a support, thereby simply and efficiently arranging the print display at the reversible display of an information display medium. SOLUTION: A release protective layer 12, a print display layer 13, a thermal recording layer 14, an intermediate layer 15, a coloring layer 16 and an adhesive layer 17 are sequentially laminated on a support 11 to form a reversible thermal recording transfer foil. As the support 11, a film or the like of a synthetic resin, a natural resin or the like such as a polyester, a polycarbonate or the like is used. The layer 12 simply transfers a reversible thermal recording medium from the support 11 to an information display medium.  The high-molecular/low-molecular thermal recording layer 14 brings about presence or absence or an air gap between a polylmeric compound and an organic low-molecular compound because melting behaviors and solidifying behaviors of the polymeric compound and the organic low-molecular compound dispersed in a matrix of the polymeric compound are different according to temperatures with the result that an emulsification and a transparency are reversibly changed.

The pulverulent material separated by the filters 4 falls toward the hopper 2. Although the bottom plate 8 of the hopper 2 is sloped at an angle of smaller than the angle of repose, the interior of the hopper 2 is kept at a negative pressure during when the clean air is sucked out through the hole 6, so that the outside air is sucked in through the gas-permeable bottom plate 8 to suspend the pulverulent material in the hopper. Accordingly, even  through the sloping angle of the bottom plate 8 is small, the pulverized material  is smoothly moved toward a discharge passage 9.
