Title: User card, communication terminal equipment, communication server, communication system and user authentication method for communication system
Inventor: NISHIYAMA YOSHITAKA
IPC: G06K17/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To simplify the operation of a user and to make the one time of data transmission/reception between a communication terminal equipment and a communication server sufficient in a user authentication protocol performed at the time of connecting the communication terminal equipment and the communication server. SOLUTION: When a password inputted to the communication terminal equipment 120 by the user matches with the password inside a password storage area, inside an IC card 100, an authenticator is generated by ciphering an ID, a serial number and a random number by a secret key. The authenticator is sent to the communication server 140 by the communication terminal equipment 120. The communication server 140 decodes the ID, the serial number and the random number from the authenticator by using the secret key and judges whether or not the ID is valid and whether or not the serial number is larger than the serial number in the authentication of a previous time from an IC card chart. Then, in the case of permitting connection, the communication server 140 returns a connection permission code and the random number to the communication terminal equipment 120.

Title: Heat-processing method for piezoelectric ceramic and acceleration sensor
Inventor: TAKAHASHI JUHEI
IPC: H01L41/22
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To invalidate pyroelectric effect even if a piezoelectric ceramics are not of the same performance. SOLUTION: When piezoelectric ceramics 2 and 3 are bonded to a metal vibration plate 1 with a bond 6, electrodes 4 and 5 of piezoelectric ceramics are heated for solidification while they are electrically shorted through pyroelectric pins 10 and 11, a pressurizing piece 7, a receiving piece 8, and a center pin 9 or shorted with a conductor comprising a resistance value. By forcedly discharging an electric charge caused by pyroelectric effect during heating/ solidification at bonding of a plurality of piezoelectric ceramics, a piezoelectric ceramics of large pyroelectric characteristics is matched with a piezoelectric ceramic of small pyroelectric characteristics, resulting in invalidation of pyroelectric effect. So, when it is used for an acceleration sensor, only an output proportional to oscillation acceleration is obtained for excluding a needless output caused by temperature.

Title: Tape traveling display
Inventor: KOYAMA NORIYUKI
IPC: G11B27/34
Filed: 1982-05-21
Abstract: PURPOSE:To display whether or not a signal is under recording, and to display the alarm warning that the tape remainder is less than a fixed value with just a signle display element, by using a recording mode signal, a recording muting signal and a tape traveling detecting signal respectively. CONSTITUTION:A transistor TR6 is turned on when the tape traveling detecting signal is se a level H and then flows a forward current to a light emitting diode 7. Then the TR6 is turned off when the detecting signal is set at a level L and prevents the current flowing to the diode 7. As a result, the diode 7 blinks with each period of 1sec. This blinking of the diode 7 can show that the recording is actually carried out. When the signal is recorded even to a tape having a remainder less than 1min, a modulated pulse waveform is applied as it to the base of the TR6 after a time point t5 equivalent to 1min of the tape remainder elapses for the space input signal waveform. Then it is displayed with the warning that the tape remainder is less than 1min share.

Abstract: PURPOSE:To improve an air-tightness and a reliability by a method wherein a large diameter part slidably contacting with a compression piston at its inner side and a small diameter part slidably contacting with a rod fixed to the compression piston at its inner side are provided. CONSTITUTION:A compression cylinder 108 is provided with a small diameter part 108b slidably contacting with a rod 111 connected to a compression piston 109 at its inner side. The small diameter part 108b is sufficiently smaller than a large diameter part 108a.

The working gas in the expansion spacing 105 passes through the heat exchanger 104. At this time, herium vapor in the tank 103 passes through a pipe 130, flows into the heat exchanger 104, cooled by the working gas of 4.2k passing in the heat exchanger 104 to become liquid, flows in a pipe 129 and then the liquid is accumulated at a liquid phase part 131a of the tank 131.

Title: Sz stranded winding grip and production thereof
Inventor: FUSE YOSHIKAZU
IPC: H02G7/02
Filed: 1995-03-20
Abstract: PURPOSE: To prevent the stripping phenomenon by subjecting a pair of leg parts formed into open spiral shape to S stranding or Z stranding and subjecting the intermediate curved part to reverse Z stranding or reverse S stranding. CONSTITUTION: Resilient metal wires 1, e.g. steel wires, are subjected to S(Z) stranding in same direction to form a pair of stranded leg parts 2, 2 on an open spiral and the intermediate curved part 3 is subjected to Z(S) stranding in reverse direction. The curved part 3 is twisted to direct oppositely, by 180 deg., to the stranding direction of the leg part when it is stranded tightly into a rope. Consequently, when the leg parts 2, 2 are wound around a linear body, inertial moments at the bent part are offset upon application of a tensile load from the other end because the linear body is stranded oppositely to the direction of spiral wire at the wire gripping part thus preventing occurrence of stripping phenomenon.  In other words, the effective length is kept in the future and a rigid and stabilized gripping structure having predetermined dimensions can be obtained without requiring any additional stripping length.

Abstract: PURPOSE:To combine a density gradation with an area gradation to perform a high-gradation reproducibility by a method wherein dots of a density gradation (n) and dots of a one rank higher density gradation (n+1) are combined in a matrix form by the plurality of number. CONSTITUTION:An image memory 1-1 storing image data GD less than one line stores data for one line by dividing it into one or more blocks. An electric conduction gradation reference means 3 holds reference data of the number of gradation which is presently under electric conduction. Upper 6 bits of the image data GD are inputted to a comparator 4. When the image data GD is larger than the reference data, the comparator 4 outputs a signal C0 (A > B).

Title: Electrostatic film actuator
Inventor: KASE TAKAAKI
IPC: H02N1/00
Filed: 1993-04-13
Abstract: PURPOSE:To provide an electrostatic film actuator which can prevent the occurrence of oblique motion by improving the orientation of the shifting of a mover. CONSTITUTION:When a mover 17 shifts sequentially in the direction of an arrow C, the mover 17 abuts on the guide member 20 provided at one end of a stator. Furthermore, when the left side in the shifting direction of the mover 17 abuts on the guide member 20, the mover 17 shifts in the direction of an arrow B in the direction of carriage while being pushed against the guide member 20. Accordingly, the mover 17 is regulated for the shifting in the direction orthogonal to the objective shifting direction (direction of arrow B), thus the occurrence of oblique motion accompanying the shifting is prevented.
