Title: Pressure controlling valve with safety mechanism
Inventor: SAKAI SHIGEO
IPC: F16K17/04
Filed: 1982-12-07
Abstract: PURPOSE:To maintain safety even if a relief valve is not of a complete closing type and leakage may be present from a primary pressure closing valve, by providing the primary pressure closing valve and a secondary pressure escape valve operated by the movement of a support shaft of a relief valve. CONSTITUTION:When pressure in a secondary pressure chamber 50 is abnromally raised, pressure in a relief side closed secondary pressure chamber 51 is raised by leakage or the like from a closed relief valve 4 to increase a relief valve body closing force due to a relief diaphragm 8 and move a support shaft 5 upward. Then, a lock lever 33 is pivoted up about a pivot 34 by a pin 35 to be disengaged from a valve stem 28 so that a primary pressure valve body 27 is pressed against a primary pressure valve seat 13 by a valve closing spring 37 to close a primary pressure closing valve. When the abnormal pressure of the high pressure fluid in the secondary pressure chamber 51 is further raised, the support shaft 5 further suceeds to move upward and a escape valve body 40 abuts against a valve opening member 10 and stops so that a secondary pressure escape valve 38 is opened and fluid in the relief side secondary pressure chamber 51 flows out of a secondary pressure escape outlet 45 through escape holes 46, 47, 48, escape groove 41 and a secondary pressure escape valve.

Title: Damping circuit for stepping motor
Inventor: SOUSHIN KOUJI
IPC: H02P8/12
Filed: 1984-10-12
Abstract: PURPOSE:To improve the damping characteristic by inserting a resistor in series with a motor coil when a step motor is stopped, and simultaneously interrupting the chopping of a transistor.

IPC: H04N1/193
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To provide an image reader capable of focusing a lens at a plurality of focal positions and reducing the manufacture cost. SOLUTION: A transparent member 20 is placed in an optical path between a face of a carriage 6 of an original platen 3 in this image reader and condenser lens 67, and when the transparent member 20 is placed at a position of the solid lines in figure, the condenser lens 67 can be focused to a transparent original above the position of a reflection original 51.

Title: Electromagnetic yoke and manufacture thereof
Inventor: OGASA YOSUKE
IPC: H02K1/06
Filed: 1994-07-13
Abstract: PURPOSE:To obtain an electromagnetic yoke producing strong rotational torque by inserting a plurality of rod members applied with insulation coating tightly between inner and outer tubes to obtain an assembly and then slicing the assembly and finishing. CONSTITUTION:When an electromagnetic yoke is manufactured, an inner tube 14 is temporarily fixed, while centering, to the center of an outer tube 13 having outer diameter about 1mm larger than the finish dimension of the electromagnetic yoke. The gap between the inner and outer tubes 14, 13 is then filled compactly with a large number of a small diameter steel wires 11 coated with an insulator 12 and the entirety is heated to bond the coating material each other. Subsequently, a steel ball or the like having outer diameter equal to the finish inner diameter of the yoke is passed forcibly to finish the inner diameter of the inner tube 14 and then the outer tube 13 is machined to have an outer diameter equal to the finish dimension of the electromagnetic yoke. Since a paramagnetic core reduces attenuation of flux in the passing direction, eddy current loss is reduced resulting in a magnetic yoke having significantly enhanced magnetic characteristics.

Title: Method for updating secret shared data in radio communication system
Inventor: PATEL SARVAR
IPC: H04L9/08
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To update secret shared data by allowing an authentication center/ home position register to respond to a session request to be transmitted and a 1st global random number and allowing a mobile device to transmit and use a keyed encryption function calculated by generating a 2nd random number and a count value. SOLUTION: An authentication center/home position register AC/HLR: 10 generates a global random number RN and transmits it together with a session request(SR) to a mobile device 20. The mobile device 20 generates a random number RM and counter value (CT) in response to this transmission and calculates and outputs a keyed encryption function (KCF)MKEY(TYPE, 0, RM, RN and CT). The device 20 increases the CT to the SR of each secret shared data(SSD) updation and then transmits its KCFMKEY. Because an attacker uses an old CT, a network does not authenticate it so that the attacker can not generate the SSD by such a manner that the AC/HLR: 10 verifies the mobile device 20 by using the KCF.
