Title: Method and apparatus for measuring length of telescopic boom
Inventor: EYLER FRANCIS R
IPC: B66C23/90
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To measure the boom length electrically at a low cost by transmitting a first signal and a second signal having lower transmission rate than the first signal and determining the length of a telescopic boom based on the difference of a transmission rate between the first and second receiving signals. SOLUTION: A transmission unit 22 transmits an RF(radio frequency) signal and an ultrasonic signal substantially simultaneously. Since the RF signal propagates substantially at the speed of light and the ultrasonic signal propagates substantially at the speed of sound, an RF receiver 38 receives the RF signal at first and delivers a reset signal to a frequency counter 42. On the other hand, an ultrasonic receiver 40 receives the ultrasonic signal and delivers a count stop signal to the frequency counter 42 which thereby stops counting of frequency. Count rate of the frequency counter 42 can be set such that the count represents the length of a telescopic boom 10 directly by setting the frequency of an oscillator 44. A boom length measurement outputted from the frequency counter 42 is presented on a display 46.

Patent JP-H0439978-A (JP)
Title: Laser oscillator
Inventor: KARASAKI HIDEHIKO
IPC: B23K26/00
Filed: 1990-06-05
Abstract: PURPOSE:To stabilize output power from a switching power source by detecting a terminal to terminal voltage of a primary side capacitor of a switching high voltage power source and controlling switching on time in conformity with the magnitude of fluctuations in a reference signal. CONSTITUTION:A voltage detector 21 detects a terminal to terminal voltage of a primary side smoothing capacitor 12 of a switching high voltage power source and inputs the detected value into an error amplifier 22. As the reference voltage of a reference voltage signal generation circuit 24 is input into the amplifier 22, differential voltage enters an output setting circuit 28. The circuit 28 controls the switching on time of a switching low voltage power source by the differential voltage to the reference voltage so that the power may be fixed and output. A drive circuit 23 switches a switching device 25 based on a switching frequency fixed from a switching frequency setting circuit 29. Therefore, the output power from the switching voltage power source does not rely on the terminal to terminal voltage of the primary side capacitor of the switching high voltage source.

Filed: 1983-08-15
Abstract: PURPOSE:To check a heat generating element from operating under the non-control condition by operating a gate circuit under normal state by another low voltage being lowered from a high voltage during the lowering of a low voltage to prevent malfunctioning of an output transistor. CONSTITUTION:When the lowering of a low voltage from a terminal 2 is detected, a switch of a power source circuit 7 is changed over with a voltage detection circuit 9 for a low voltage power source and a low voltage is supplied to a gate circuit 3 from a voltage lowering circuit 8 for lowering the high voltage from a terminal 20. Consequently, the circuit 3 operates normally to generate a low level output without the supply of the power to a logic circuit 1 and an output transistor 5 is turned OFF through a level shifter and a buffer circuit 4 to prevent malfunctioning. Thus, a heat generating element 6 is checked from operating under the non-control state thereby eliminating breakdown of the element 6 due to overcurrent.

Abstract: PURPOSE:To form a surface skin free of bridge by a method in which a thermoplastic resin sheet fixed to a clamp is heated and adhered to the inner surface of molds by evacuation to vacuum, and all clamping is released at a time when the temperature at which the resin sheet shows maximum elongation is reached approximately.

Title: Data transmission equipment
Inventor: KOBORI TOSHIO
IPC: H04B3/04
Filed: 1985-07-08
Abstract: PURPOSE:To make signals transmitted to a telephone circuit uniform at all times by simple constitution by providing a level adjusting circuit controlled by an input signal of a conversion means in an output side of a signal conversion means. CONSTITUTION:When the value of a variable resistance VR1 is made larger than the value of a variable resistance VR2, the TR2 becomes on and TR3 becomes off at the moment when the data signals are low level. Accordingly, attenuation of the signals caused by the level adjusting circuit becomes relatively large. Therefore, the signals are amplified by the TR1 and signals shown in the figure C are outputted. Thereby, signals transmitted to telephone circuits L1, L2 become nearly uniform level as shown in the figure D.
