Title: Plasma spray torch
Inventor: NOTOMI HIROSHI
IPC: H05H1/42
Filed: 1995-02-02
Abstract: PURPOSE: To provide a plasma spray torch with an elliptical nozzle hole obtaining a flat spray pattern for efficient spraying. CONSTITUTION: A nozzle hole 1a is formed out of an anode nozzle 1, a cathode 2 and an insulator 3. Also, the cathode 2 and the hole 2a are both formed elliptical and the anode-cathode distance is constant all around. Gas is supplied from a gas feed port 4 and magnetic field is applied from an electromagnetic oil 7. An arc is thereby generated between the electrodes to blow a plasma jet through the nozzle hole 1a. In this case, the sectional area of the plasma jet is elliptical and, therefore, a spray pattern for workpiece surface also becomes elliptical. Furthermore, the arc rotates, due to the existence of the magnetic field. Thus, the repetition of the conventional circular motion is eliminated, when a flame is sprayed over a wide range. According to this construction, a flame can be stably sprayed over a wide range, and flame spraying efficiency can be improved.

IPC: B25B23/157
Filed: 1994-02-10
Abstract: PURPOSE:To provide a torque limiter particularly suitable for high-speed rotation, and capable of expanding a setting range for preset values. CONSTITUTION:This limiter has a pulley 3, an output shaft 4 and a torque setting member 5 for determining a degree of coupling between the pulley 3 and the output shaft 4. The member 5 is formed out of a piston 7 subjected to the compressed air, a pusher pin 8 subjected to the axial thrust of the piston 7 and a steel ball 9 pushed to a cam section 12a due to the thrust of the pin 8. When the torque 4 of the shaft 4 is equal to or lower than the preset value determined with the degree of bonding, the ball 9 and the cam section 12a are kept in coupled state, and the torque of the pulley 3 is transmitted to the shaft 4. When the torque of the shaft 4 exceeds the preset value, the condition of the ball 9 and the cam section 12a changes to non-coupled state, thereby causing the idle running of the pulley 3. The piston 7 rotates integrally with the pulley 3 via a coupling pin 10a on a static bearing generated due to the compressed air.

Title: Negative resistance element
Inventor: KAWAMURA YUICHI
IPC: H01L47/00
Filed: 1989-01-30
Abstract: PURPOSE:To eliminate influence of scattering due to lattice vibration at the time of high temperature and to provide a large negative resistance voltage range at an ambient temperature by doping n-type impurity in quantum well layers of a resonance tunnel type multiple quantum well structure negative resistance element. CONSTITUTION:Undoped InAlAs layers (a) to become barrier layers and n-type doped InGaAs layers (b) to become well layers are alternately laminated on an n-type InAlAs semiconductor 2 on an n-type InP board 1 to form a multiple quantum well layer 3. Si is employed as an n-type dopant. If an applying voltage Va is smaller than a flat band voltage Vb, a current scarcely flow to the element. When the voltage Va is raised to become near the voltage Vb, the quantum well layers become resonance tunneling state, and the current abruptly increases. When the voltage Va increases over the voltage Vb, an excess voltage is applied to one of the multiple quantum wells to break the resonance tunneling state. Thus, the current is abruptly decreased, and a negative resistance is generated. Since this effect is repeated in the number of the quantum wells, an extremely large negative resistance region can be obtained even at temperature.

Title: Frequency-voltage converter
Inventor: NAKAMURA MITSURU
IPC: H03D3/00
Filed: 1978-02-20
Abstract: PURPOSE: To avoid occurrence of the error caused by the duration of the reference clock pulse for the frequency-voltage converter by providing the trigger flip-flop to secure the synchronization between the rectangular wave output and the reference clock pulse.  
     CONSTITUTION: When rectangular wave input 12 changes from "0" to "1", pulse counter 8 varies from the reset state to the active state. And trigger flip-flop 21 varies rectangular wave output 24 from "0" to "1" to deliver it by the first-shot reference clock pulse 17 after input 12 turned to "1". At that instant, counter 8 starts counting and resets flip-flop 21 after counting up to the prescribed number. Thus, output 24 is changed from "1" to "0", and the counting is stopped. In this way, the rise of output 24 is synchronized with the occurrence time point of the reference clock pulse, thus ensuring constant pulse duration t 5  for output 24 at all times.
