Title: Direct brake device
Inventor: ITOU YOSHINORI
IPC: H02P3/24
Filed: 1982-06-21
Abstract: PURPOSE:To prevent excess braking current from flowing by detecting the stopped state of an induction motor from counterelectromotive force produced when a DC voltage is applied to the motor after a power source is interrupted at the direct braking time, and interrupting the application of the DC voltage. CONSTITUTION:If a switch SW is closed when an induction motor M20 is stopped, a relay RL20 is deenergized, a relay RL21 is energized an SCR20 is energized by the interruption of a transistor Tr23 via the energization of a photocoupler PC20 due to OFF of the layer RL, and a DC braking current is flowed to the motor M20. Counterelectromotive forces produced between V and W and between U and W are respectively rectified by transformers T20, T21, the sum is detected, compared with a referece voltage which is charged in the condenser of a zero detector 23 when a power source is energized thereby generating a zero detection signal to know the OFF of the power source. The zero detection signal is inputted to a delay circuit 24, and as the motor M20 is decelerated, it is reduced to 0V. As a result, the transistor Tr22 is turned OFF, while the Tr21 is turned ON via the circuits 23, 24, and the SCR20 is turned OFF, thereby finishing the application of the DC voltage to the motor M20.

Title: Acoustooptic element
Inventor: NISHIYAMA SUMI
IPC: G02F1/11
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the emitting azimuth of transmitted light from changing without reference to whether a high-frequency electric signal is inputted or not by arranging heat radiation members on the side end surface of the acoustooptic element where heat is generated. CONSTITUTION:First and second metal blocks 4 and 5 are adhered to the end surface 1a of the acoustooptic element 1 in a case 2 where a piezoelectric transducer 3 is fitted and the other end surface 1b facing said end surface 1a, and they are arranged in contact with the case 2. When a high frequency electric signal is inputted to the piezoelectric transducer 3, the transducer 3 transduces the signal into an ultrasonic wave and part of the electric signal becomes heat because of transduction loss. This heat is radiated from the metal blocks 4 and 5 as the heat radiation members, so the temperature distribution of the medium 1 becomes uniform and the refractive index does not vary, so the emitting azimuth of the transmitted light never changes.

Title: Discharge lamp lighting device
Inventor: NAKAYAMA YASUO
IPC: H05B41/282
Filed: 1989-04-28
Abstract: PURPOSE:To provide a small and lightweight lighting device for a discharge lamp, in which occurrence of acoustic resonant phenomenon is precluded, by feeding the high-frequency output rectified by a rectifier circuit to a low-frequency inverter, thereby converting into a rectangular wave of low frequency, and feeding it to a discharge lamp in the form of high-voltage pulses via a trigger circuit. CONSTITUTION:Output of a high-frequency inverter H is fed to a rectifier circuit D1, composed of diodes in bridge connection, through a ballast CH of, for ex., a capacitor or a choke coil. The output of this rectifier circuit D1 is fed to a low-frequency inverter LF, and a low-frequency inverter LF emits a rectangular wave with as low a frequency as not causing occurrence of acoustic resonance phenomenon within a discharge lamp DL. A trigger circuit TG is furnished, which receives this rectangular output and emits pulses with as high a voltage as capable of starting the discharge lamp DL, which is thus lit up with rectangular waves at a frequency in the degree which does not allow occurrence of the acoustic resonance phenomenon. This accomplishes a small and lightweight lighting device, with which lighting can be maintained with frequencies not generating acoustic resonance phenomenon.

Title: Steering wheel angle compensating device for industrial vehicle and industrial vehicle provided with the same
Inventor: ISHIKAWA KAZUO
IPC: B62D123/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To make the amount of compensation per unit time nearly constant irrespective of the magnitude of the pressure of a steering cylinder when a steering wheel angle is compensated. SOLUTION: An actual position of a steering wheel 2 is detected by a rotary encoder 27 and the steering angle of a steering wheel 19 is detected by a potentiometer 28. A CPU calculates a target position corresponding to the steering angle of the steering wheel 19. When the amount of deviation of the actual position of the steering wheel 2 from the target position exceeds an allowance, a duty valve 22 is driven to reduce the rate of change between the amount of drive of a steering cylinder 12 and the amount of operation of the steering wheel 2 and to idle the steering wheel 2, whereby the position of the steering wheel 2 is compensated at least until the amount of deviation is reduced in the range of allowance.  The duty valve 22 as a compensation means is set such that the duty value of the duty valve 22 is reduced in response to an increase in the detected pressure of a pressure sensor 37. Therefore, the amount of compensation per unit time is made nearly constant irrespective of the pressure of the steering cylinder 12.

Abstract: PURPOSE:To enable easy setting of a photocurrent of a light-sensing element at a prescribed level and also to enable detection of a body to be detected, with high sensitivity, by adjusting the quantity of light entering the light-sensing element by a light quantity adjusting mechanism. CONSTITUTION:A passage 12 for a body to be detected, which intersects an optical path 6 perpendicularly, is provided in the main body 4 of a case. When the body 14 to be detected, such as a lead core, passes through this passage 12, a light on the optical path 6 is intercepted by the body 14 to be detected and the quantity of the light entering a light-sensing element 10 lessens. A detecting circuit element detects a change in a photocurrent of the light-sensing element 10 and outputs a detection signal of the body 14 to be detected. When a screw 18 provided at the optical path 6 is operated to rotate, the fore end of the screw 18 is projected into or withdrawn from the optical path 6. By varying the amount of projection of this screw 18 into the optical path, therefore, the quantity of the light entering the light-sensing element 10 can be adjusted. In other words, the level of the photocurrent of the light-sensing element 10 in a state wherein the body 14 to be detected does not intercept the optical path 6 can be adjusted.
