Title: Multi-axis joystick
Inventor: MURAI TOMOHIRO
IPC: B25J13/02
Filed: 1994-08-29
Abstract: PURPOSE: To enable linear commands to be done precisely by providing displacement sensors which detect position command signals, produced via a grip, as rotary or linear displacement from a neutral point by way of a neutral point return mechanism, and providing a sensor beam with a force sensor for detecting moment applied to the grip. CONSTITUTION: Displacement sensors 54, 88, 40 detect the displacement of a rectangular three-axis mechanism along the X-, Y- and Z-axes, respectively. In this case, when the operator relieves a grip 10 of the operating force, the grip 10 is restored to a neutral point by the action of a spring return mechanism 90. The amounts of rotation of the grip 10 about the X-, Y- and Z-axes are detected by a force sensor 110. Linear movability can thus be enhanced during the operation of the grip; i.e., after the operations along each axis, the grip always restores to the neutral point, allowing the difference between the operations along the axes and about the axes to be easily sensed by hand.

Title: Four-wheel steering device for car
Inventor: MIYOSHI AKIHIKO
IPC: B62D5/30
Filed: 1984-10-31
Abstract: PURPOSE:To prevent the effect of fine car speed variation during running by inputting a car speed signal for controlling in which a car speed sensor signal is hysteresis-processed at preset width to a controller that controls the four- wheel steering based on the car speed. CONSTITUTION:The rotation of a stepping motor 29 is controlled by a control signal sent to a motor driving circuit 30 from a controller 31 which receives the sensing signals coming from an angle of oscillation sensor 33 that senses the angle of oscillation of an oscillating shaft 23 provided on an oscillating support shaft 24 and a car speed sensor 32 that senses the car speed through a hysteresis processing section 34. The car speed singal sent to the controller 31 is not a signal itself that is sensed by the car speed sensor 32 but the signal that is hysteresis-processed by the hysteresis processing section 34. As a result, this hysteresis processing can perform stable control that will not transmit the fine variation of the car speed.

Title: Zn-cr-p organic composite plated steel sheet having excellent post-working corrosion resistance, ed coating corrosion resistance and pitting resistance
Inventor: ODAJIMA TOSHIO
IPC: C25D5/26
Filed: 1991-08-16
Abstract: PURPOSE:To provide the Zn-Cr-P org. composite plated steel sheet having excellent corrosion resistance after working and ED coating corrosion resistance and end excellent pitting resistance. CONSTITUTION:This steel sheet is constituted by having an electroplating layer of a Zn-Cr-P alloy having 2 to 14% Cr concn. and 1 to 5% P concn., and consisting of the balance Zn and by having a chromate layer thereon and further coating the surface thereof with an org. resin. The reason for the improvement of the bare corrosion resistance after working by adding the P at the specific concn. lies in that the Cr of the plating layer is fixed by the presence of the P and the bare corrosion resistance of the plating layer itself is improved. In addition, the dense and stable chromate film is formed by the presence of the P when the plating layer is subjected to a chromate treatment. The corrosion resistance of the Zn-Cr-P alloy is greatly improved by the presence of such special chromates. In addition, the excellent adhesion to the film of the org. org. composite plated steel sheet is assured. The org. film protects the chromates and maintains the excellent function over a long period of time if the org. film is further formed thereon. The excellent characteristics are obtd. by the synergistic effects thereof.

IPC: G01J5/34
Filed: 1985-10-17
Abstract: PURPOSE:To simultaneously measure the position and temp. of infrared rays with a small-sized apparatus, by providing a conductive film on one surface of a polarized pyroelectric film while providing a resistor layer guiding a pyroelectric current generated by incident infrared rays to the other surface thereof and further providing a plurality of electrodfes at the end parts of said resistor layer. CONSTITUTION:The charge generated on a pyroelectric film 11 by incident light converged to said pyroelectric film with respect to infrared rays from Ge is earthed through electrodes 13, 13' divided left and right on a resistor film 12 and a resistor R. Currents iA, iB flowing to the electrodes 13, 13' act as functions of the incident light position (x) on the pyroelectric film 11. When the total length of the pyroelectric film is set to 2L, (x) is calculated according to a formula x=(iA-iB)XL+L by a position judging operator 24 and the position of a light source is calculated from the constant of an optical system. Because a rise in temp. at this time is the function of a total pyroelectric current iA+iB, said rise in temp. is immediately calculated if calibration is preliminarily corrected. Therefore, the position and temp. of infrared rays from a near infrared region to a far infrared region can be simultaneously measured by a small-sized apparatus.

Title: Steam safety valve
Inventor: KAWAMI MASAYUKI
IPC: F16K17/10
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent generation of pre-leakage by connecting a seal pot to a power assist cylinder which presses a valve rod of a spring type safety valve by means of a connection pipe, and providing a pilot safety valve which is connected to the communication pipe and made open with a specified pressure level or above. SOLUTION: The operation pressure of a pilot safety valve 4 is set slightly higher than a pre-leakage pressure of a spring safety valve 1. The pressure of a pressure vessel 01 rises over the specified pressure, that is, the pre-leakage pressure, the valve 4 is operated to release the pressure of a power assist cylinder 3. Namely, the moment the pressure in a seal pot 5 reaches a blow-out pressure, the valve 4 is operated to release the internal pressure of a cylinder 14. Then, a valve element 9 to which no pressure is added opens rapidly against the force of a spring to blow out steam. When the pressure of the vessel 01 reaches a blow-up pressure, the element 9 is sealed by the spring force. Accordingly, the leakage of safety valve is prevented.
