Title: Pilot check valve
Inventor: ISHIZAKI KENJI
IPC: F16K15/18
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To surely operate a hollow plunger to open a valve even if flow rate supplied to an inlet port is abruptly increased by providing a bypass path 24 interconnecting the inside of a hollow part 15 and outlet port 3 and a free flow check valve in the bypass path to be opened by pressure in the hollow part. SOLUTION: A bypass path 24 interconnecting the interior of a hollow part 15 and an outlet port 3 is provided, and a free flow check valve 25 opened against a spring 26 by the pressure in the hollow part 15 is provided. When the pressure in the outlet port 3 is larger than the pressure in an inlet port 2 and the pressure is introduced into a pilot pressure circuit 22, a pilot piston 11 thrusts a small plunger 20 to open a communicating port 16, and a flow from the outlet port 3 through an orifice 17 for the differential pressure, the hollow part 15 and the communicating hole 16 to the inlet port 2 is generated. Thus, the pressure in the hollow part 15 which was so far the same pressure is reduced to the intermediate one between the outlet port 3 and inlet port 2, and a hollow plunger 8 is operated in the direction of opening the valve so that the valve can follow up the move of a small plunger 20 to be fully opened.

Title: Power feeding device
Inventor: SUNADA HIRONAO
IPC: B60L50/16
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a power feeding device capable of making high accuracy in operation compatible with accelerating performance. SOLUTION: The operation of a table 4 can be made high in accuracy by driving the table 4 by means of a ball feeding screw 6. However, when it is essential to accelerate the table 4 largely, the accelerating capacity of a motor 5 is limited by its time constant and rising current and the like. Furthermore, its acceleration is prevented from being increased by the rotational inertia of the ball feeding screw 6. In that place, let a first and a second rotor 9 and 10 rotating at a definite speed, abut against a moving plate 8 fixed to the table 4, the accelerating performance of the table 4 is thereby enhanced. Besides, after the table 4 has been accelerated up to a specified speed, the table 4 is driven only by the ball feeding screw 6 by letting the first and second rotors 9 and 10 be separated from the moving plate 8, its operation can thereby be made high in accuracy.

Title: Pseudo random bit string generator and cipher communication method using the same
Inventor: KIYATAKE MORIMOTO
IPC: H04L9/24
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To enhance the safety of a pseudo random bit generator in which plural feedback shift registers(FSRs) are used with a simple circuit constitution while improving short preiodicity by selecting the plural shift resisters (FRSs) having prime lengths each other and exclusive ORing outputs of the selected FRSs. SOLUTION: Eight FRSs having prime lengths each other are used as the numder of registers suitable for the pseudo random bit generator and the outputs of respective FSRs are combined in an exclusive OR. Then, seeds are opened to the public and the FSRs are selected every communication with software by an auxiliary circuit H and the selection data (data set in the circuit H) are enciphhered to be transmitted from a transmitting side to a receiving side. When the designing of this bit string generator is performed by this method, since the selection data are of 8 bits, a transmission efficiency is never lowered even when a complex enciphering is performed. Moreover, since the generating of a bit string is changed every communication, this cipher communication method is resistant to the attack.

IPC: H01B5/14
Filed: 1988-09-30
Abstract: PURPOSE:To lower specific resistivity without lessening light permeability by substituting a part of Sn of a specific SnO2-based composition with Si and Sb. CONSTITUTION:The composition ratio (x) of Si with which a part of Sn in a formula (I) (Sn+x+y=1) is substituted is defined in a range of 0.001-0.010 since in the case (x) is <=0.001, the effect on grain size increase is not sufficient and in the case (x) is >=0.010, Si is segregated in crystal and resistivity is increased. Also, the composition ratio (y) of Sb is defined in a range of 0.003-0.005 since in the case (y) is <=0.003, the effect on resistivity decrease is not sufficient and in the case (y) is >=0.005, permeability decreases. The ratio (w) of 0 is defined in a range of 1.80-2.05 since in the case (w) is <=1.80, SnO is formed in the film and permeability decreases and the composition with (w) >=2.05 can not exist. With the defined composition ratio, specific resistivity of the title film is lowered without lessening light permeability.

Abstract: PURPOSE:To improve energy efficiency, to obtain low speed and high torque and to improve responding properties by setting the radial oscillation mode of a stator as a primary natural resonance oscillation mode. CONSTITUTION:The output signal of an oscillator 19 is divided into two parts, and one part is inputted directly to an amplifier 20 and the other part, to an amplifier 22 via a phase shifter 21.
