Filed: 1978-11-01
Abstract: PURPOSE:To make it possible to obtain a feedback amplifier with a low distortion factor and high stability, by setting the amount of the phase of a feedback loop nearly equal to a value odd-number greater than the half of wavelength equivalent to an in-use band frequency. CONSTITUTION:Signals from input terminal 1 are inputted to transistor amplifier 5 by way of directional coupler 2, BPF3 and isolator 4.

Title: Strobe with operation indicating means
Inventor: KATAYAMA MASAE
IPC: H05B41/14
Filed: 1979-10-22
Abstract: PURPOSE:To indicate whether the oscillating circuit for strobe is operating or not, by lighting the LED and so on through the diode where the reverse voltage generated in the primary winding of the oscillation transformer is utilized. CONSTITUTION:When switch 6 is closed, a current is flowed to feedback winding 5 of oscillation transformer 2 through resistance 10, and transistor 7 becomes conductive to flow the current to primary winding 3 of transformer 2. Since this current is the opposite polarity, diode 11 does not become conductive, and LED 13 is not lit. Next, oscillation dependent upon inversion of the voltage polarity of winding 3 and so on accompanied with increment till the saturation point and reduction from the saturation point of the collector current of transistor 7 is performed to light LED 13. Main capacitor 9 is charged by this oscillation, and oscillation is stopped when transistor 16 becomes conductive through capacitor 15 after a prescribed time, and the LED is left extinguished, thus indicating whether the oscillation operation is being performed or not.

Title: Oil pressure circuit for construction machinery
Inventor: ARAI MITSURU
IPC: E02F9/20
Filed: 1980-09-30
Abstract: PURPOSE: To prevent the occurrence of cavitation due to the shortage to suction in the oil-pressure circuit of an oil-pressure type rotary excavator, etc., by using a system in which a brake valve is made up of two counter-balance valves and return oil from an oil-pressure motor is directed toward the suction side of the oil-pressure motor.  
     CONSTITUTION: Oil pressure of an oil-pressure pump 1 is supplied through an operating valve 2 and a brake valve 3 to an oil pressure motor 4 to turn the motor 4, whereby driving a load 4a. In this case, the brake valve 3 is made up to the first counter-balance valve 5 and the second counter-balance valve 6. When restoring the operating valve 2 to neutral position to stop the load 4a, the first valve 5 is instantaneously restored to neutral position and the second valve 6 is slowly restored to the neutral position by throttles 15 and 16 provided in a pilot circuit. Thus, even when the oil-pressure motor 4 is driven by loading inertia, the occurrence of cavitation due to the shortage of suction can be prevented without causing oil shortage on the suction side of the oil-pressure motor 4.

Title: Optical fiber sensor
Inventor: ITO RYOICHI
IPC: G01P15/08
Filed: 1989-05-29
Abstract: PURPOSE:To obtain an optical fiber sensor which is sensitive to temperature and pressure without special apparatus for coating by using a shape memory resin as a coating material for optical fiber. CONSTITUTION:A shape memory resin is used as a coating material for optical fiber. The shape memory resin is hardened at temperature lower than a specified temperature and protects the optical fiber against side pressure. The resin is softened at temperature higher than a specified temperature and becomes sensitive against the side pressure. When deformation larger than a specified value is imparted, the deformed state remains at temperature lower than a specified temperature. When the specified temperature is exceeded, the shape returns to the shape before the deformation. When residual strain in the tensile direction is imparted to the coating material beforehand, the strain is released at first when the material is heated to the temperature higher than the specified temperature. The side pressure is momentarily applied to the fiber by the contraction at this time. The transmission loss in the optical fiber is rapidly increased. Since the temperature increase can be detected by monitoring, this sensor is effective as a temperature sensor.

Title: Square nonacqueous electrolyte battery
Inventor: HASHIMOTO SHUICHI
IPC: H01M10/058
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To pressurize a polar plate group without increasing the number of battery components and to suppress local charging/discharging reaction in a polar plate surface by setting a battery inner pressure lower than the atmospheric pressure. SOLUTION: Argon gas is supplied into a square type battery container 4 under a pressure lower than the atmospheric pressure. As a result, the surfaces opposite the polar plate surface os positive and negative electrode plates 1 and 2 are elastically deformed inside, a pressure is applied on a polar plate group and thereby the polar plate group is fixed. Thus, local charging/ discharging stress in a polar plate surface and the increase of internal resistance are suppressed. But a battery inner pressure is preferably set in the range of 450 to 610 mmHg. If a pressure higher than 610 mmHg is set, a pressing force is insufficient and thus a sufficient effect is not provided. Under a pressure lower than 450 mmHg, an excessive pressure is applied on the electrode surface, an electrolyte holding amount is reduced and an active material using rate is reduced.

Title: Surface treatment of aluminum support for printing plate
Inventor: YAMAZAKI TORU
IPC: C02F1/78
Filed: 1992-04-30
Abstract: PURPOSE:To provide a method for treating the surface of an aluminum support for a printing plate which suppresses and prevents slime from generating and growing in a water wash tank. CONSTITUTION:An aluminum plate is surface-treated in an etching process tank 1, an electrolytic process tank 2 and an anode oxidation tank as treatment tanks. In an aluminum support 8 coming out of the process tanks 1, 2 a treatment liquid sticking to the surface is removed by a nip roll 7a. However, as the nip roll 7a alone is not effective enough to remove the treatment liquid completely, the liquid is washed off from the aluminum support 8 using a spray water. Slime which generates in the water wash tank is mostly, composed of Zoogloea bacteria or water molds. Its generation and growth can be inhibited by using water wash water in which min. 0.1PPM of ozone is injected or using a copper spray pipe or a copper-plated spray pipe (purity: at least 60%) in the water wash tank.

Filed: 1993-06-07
Abstract: PURPOSE:To obtain a frequency multiplier circuit having high accuracy and a pulse time interval measuring device. CONSTITUTION:A reference clock generated from a reference clock oscillator 9 is multiplied by a frequency multiplier circuit 10 to generate a subclock. The number of clocks from an initial input pulse to be measured to a final input pulse to be measured is counted by a main time counter 11.

Then terminating resistance RE is connected to the termination of the line, and at the same time the sensors such as differential spot 1 1 , smoke senson 1 1 , constant-temperature spot 1 3  and others are connected to the intermediate part. Thus, the micro monitor current of about 3mA is flown at all times to sensor circuit L via relay RY and resistance RE. Current transformer CT uses the circular core and makes line l 1  of circuit L pierce through the through- hole to use it as the primary winding. Then disconnection detector circuit A detects the secondary output of CT to secure an automatic detection of the disconnection through the variation of the secondary output.
