Title: Column for producing ultra-pure water
Inventor: NOYORI MASARU
IPC: C02F1/72
Filed: 1989-11-02
Abstract: PURPOSE:To obtain the column for producing ultra-pure water which easily produces the high-purity water extremely approximate to the theoretically pure water at a high velocity of flow and obviates the fresh elution of impurities by integrating a UV lamp, ion exchanger, precision filter membrane and/or ultrafilter membrane in this order. CONSTITUTION:The water to be treated is irradiated with UV rays 4 and the org. impurities contained therein are decomposed by oxidation. The org. acids and carbon dioxide formed by the oxidation decomposition and the other impurities in the water to be treated are then treated by the ion exchanger 6 and are further subjected to the final filtration by the precision filter membrane and/or ultrafilter membrane 9. The ultra-pure water is thus obtd. without using piping systems for transferring the water to the ensuing stages. The need for pipings and joints is eliminated by the above-mentioned integration and, therefore, the extremely compact column for producing the ultra-pure water is provided. In addition, the degradation in the water quality by the pollution with the impurities eluted from the members, etc., are prevented.

IPC: H03K5/13
Filed: 1985-12-19
Abstract: PURPOSE:To obtain a delay circuit stable in the variation of elements and the temperature characteristic by using a MOS transistor (TR) in place of a comparator so as to exclude the effect of an input current. CONSTITUTION:When an input signal fed to a logic signal input terminal 9 goes to a high level, a capacitor 5 is charged by a current I2 of a constant current source 2. Then an output signal is delayed by a time until an input voltage of the MOS TR 12 reaches a threshold value. In constituting the TR 12 by a MOS TR in this way, the effect of the input current is neglected in comparison with a comparator of bipolar TR constitution and number of circuit components is reduced.

Abstract: PURPOSE:To detect a speed highly accurately even if the amplitude of irregular reflected waves are weak by operating a frequency measuring means when the amplitude level of the irregular reflected waves exceeds a specified level, and computing the frequency of the irregular reflected waves. CONSTITUTION:A continuous ultrasonic signal whose amplitude is largely changed by the changes in wind and temperature and the like from a road surface 3 or the change in irregularities on the road surface and the like is transduced into an electric signal with a receiver 4. Only when the signal having the amplitude exceeding a specified slice level among the electric signals is inputted, a rectangular pulse is generated and inputted into a frequency counter 9. The counter 9 counts the number of the rectangular pulses inputted within predetermined period. The frequency is computed based on the counted value. The speed that is operated based on the frequency is sent to a speed display part 11 in the form of a digital signal. When the amplitude of the electric signal becomes very weak, the slice level is not exceeded, and the rectangular pulses are not generated. Therefore, the rectangular form is shaped in an envelope circuit 8, and a gate signal is generated and inputted to an enable terminal 10.

Title: Photoelectric switch
Inventor: HARA MASATO
IPC: H03K17/78
Filed: 1985-12-20
Abstract: PURPOSE:To prevent the degradation of a semiconductor laser to hold a stable characteristic for a long time by providing an integrating capacitor in the output part of a negative feedback voltage of an APC circuit and operating the APC circuit when a transistor TR is turned on. CONSTITUTION:A capacitor C1 is connected to a TR3 of an APC circuit 3. The capacitor C1 integrates the feedback voltage of the emitter of a TR3, and its capacity is selected on a basis of the frequency and the duty ratio of pulses of a pulse generating circuit 1. While a series of pulses are given from the pulse generating circuit 1, the emitter voltage of a TR 2 rises and falls repeatedly in a prescribed range. Consequently, the APC circuit 3 starts the operation immediately when a TR1 is turned on. That is, the APC circuit 3 is operated approximately simultaneously with turn-on to limit the driving current of a laser diode LD because the emitter voltage of the TR3 is held at a certain value, thereby eliminating the overshoot.
