Title: Overvoltage surge protection system
Inventor: WATANABE YOSHIO
IPC: H02H9/04
Filed: 1990-08-09
Abstract: PURPOSE:To effectively protect against an overvoltage by integrating a surge current flowing to a constant-voltage element by a capacitor in series with the element, and stopping the operation of the circuit when the integrated voltage becomes a predetermined value or more. CONSTITUTION:A series circuit of a diode 17, an avalanche diode 16 and a capacitor 18 is connected in parallel with a transistor 12. When an overvoltage surge is generated at the end of the transistor 12 to become the clipping voltage or larger of the diode 16, the diode 16 is conducted, and the capacitor 18 is charged. When the charging voltage of the capacitor 18 becomes a predetermined value and a voltage of a resistor 20 side divided by resistors 19, 20 becomes a trigger voltage or higher of a thyristor 15, the thyristor 15 is conducted to substantially short-circuit between the base and the emitter of the transistor 12. The transistor 12 is interrupted.

Title: Sprinkling method of antifreeze
Inventor: UESUGI SHUJI
IPC: E01H10/00
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To improve a sprinkling function by transferring rearward a dry antifreeze in a hopper of a sprinkler car by a screw conveyor and sprinkling it after wetting it with water or the like. SOLUTION: When sprinkling an antifreeze onto a road face by a sprinkler car, after a dry antifreeze has been fed into a hopper 2, a screw conveyor 3 is driven to lead the antifreeze rearward from the hopper 2 to the front end of the conveyor 3. Then a solution such as water is injected to the antifreze which has reached the terminal end of transfer of the conveyor 3 to wet it. The wet antifreeze is fed onto a rotary splinkler disk of a splinkler device 4 from the discharge outlet of the conveyor 3 through a chute to splinkle it on a road face. In this way, the antifreeze can be securely wetted and the residual quantity of the antifreeze left in the screw conveyor at the completion of the sprinkling work can be minimized.  Further, even if the wet antifreeze is solidified due to the low temperature outside air, as it is solidified only at the terminal end of the conveyor, it can be securely removed in a short time.

Title: Brightness adjusting circuit
Inventor: ISHIZUKA KUNIMITSU
IPC: H04N5/59
Filed: 1983-11-11
Abstract: PURPOSE:To simplify circuit constitution, to reduce its cost and to enhance a spot killer effect by connecting a means, which interrupts supply of brightness adjusting voltage when it becomes a certain voltage, to the side supplying the brightness adjusting voltage to a variable resistor in terms of a display having a brightness adjusting circuit. CONSTITUTION:A transistor R in a spot killer circuit is normally energized, and the spot killer circuit supplies a voltage Vg (-40V) which is obtained by dividing voltages Vk (+60V) and Vd (-100V) by a variable resistor RV to the 1st grid G1 of a CRT1. When power supply is turned off under this condition, the voltage Vk (+60V) is falling. When the voltage is lowered below Zener voltage (30V) point (b), the transistor T is brought into the interrupted condition. Due to this interruption a supply voltage Vg to the 1st grid G1 is directly applied to a discharge voltage of -100V of a condenser C1, and a potential difference Vkg between a cathode K voltage Vk and the 1st grid G1 voltage Vg becomes larger; therefore emission of electronic beams is cut off and a spot will not remain.

Patent JP-H0493762-A (JP)
Title: Acoustic emission sensor
Inventor: OHARA KEISHIN
IPC: G01N29/14
Filed: 1990-08-10
Abstract: PURPOSE:To enable detection of longitudinal vibration alone and also improvement of detection sensitivity by a construction wherein a plurality of columnar ceramic SM piezoelectric bodies each polarized in the axial direction are arranged in a synthetic resin matrix MT so that they are parallel and shaped in concentric circles. CONSTITUTION:A synthetic resin-SM composite piezoelectric element 7 is prepared by arranging columnar SM piezoelectric bodies 1 in synthetic resin MT 2 so that they are parallel substantially in a direction and shaped in concentric circles. The crystal axis of each piezoelectric body 1 is oriented in the direction of the height and polarized in this direction. When a reception plate 3 is brought into close contact with the surface of a body to be inspected, an acoustic emission AE wave generated inside the body to be inspected is propagated through the body, reaches the surface and is transmitted to the piezoelectric element 7 through the reception plate 3 and others, and thereby the piezoelectric bodies 1 is made to extend and contract in the direction of the height. A potential difference occurs between the opposite ends of the piezoelectric body 1 by these extension and contraction and it is taken out as an AE signal. On the occasion, the piezoelectric body 1 is polarized in the direction of the height and so only a longitudinal vibration component in the AE wave is detected. Since the piezoelectric bodies 1 are arranged in the shape of concentric circles, besides, the longitudinal vibration causes no transverse vibration and thus detection sensitivity is improved.
