IPC: H03K7/06
Filed: 1983-10-20
Abstract: PURPOSE:To simplify the circuit by providing a polarity inverting circuit and a bipolar voltage-current converting circuit so as to reduce waveform distortion and also decrease number of components. CONSTITUTION:A buffer amplifier 9 outputs an input voltage Vi as a voltage Vi' of opposite polarity. The polarity inversion circuit 10 receiving this output outputs alternately a voltage + or -Vi by using a polarity switching signal. The bipolar voltage-current converting circuit 11 receiving this output outputs alternately a delivery current +I and a suction current I' proportional to an input voltage. Then an integration circuit 6 inputs an output of the converting circuit 11 and outputs a triangle wave output e0 having a frequency proportional to the input voltage Vi. Furthermore, a hysteresis switch 7 forms a polarity switching signal based on the output of the integrator 6 and also outputs a rectangular wave output (f). The waveform distortion is reduced in this way and number of components is decreased so as to simplify the circuit.

Filed: 1987-08-07
Abstract: PURPOSE:To measure the density of chlorine ion accurately irrelevant to the presence of melamine sulfonate, by adding boric acid to a ready-mixed concrete to perform a measurement with the density of hydrogen ion below 7.0. CONSTITUTION:A chlorine ion measuring electrode body 1 is made of a sensitive film 3 comprising a mixture of silver chloride and silver sulfide fixed at one end of a cylindrical support 2 and a silver line 4 connected to the back of the film 3.

Title: Method and device for controlling battery charge
Inventor: KANO MITSUNARI
IPC: H01M10/48
Filed: 1993-08-10
Abstract: PURPOSE:To control battery charge so as to secure the charging operation and utilize battery capacity effectively in the case where a voltage difference is detected when the voltage-across-battery is lowered before finishing a charge on the basis of a change of voltage, which is detected periodically, by continuing the charge when a value of temperature rise detected periodically is a predetermined value or less, and finishing the power generation when the detected value exceeds the predetermined value. CONSTITUTION:In the case where a battery 1 is charged quickly from a constant current circuit 5, finish of the charge at -DELTAV voltage (a difference when the voltage-across-battery is lowered before the charge is finished) is detected on the basis of a value (temperature of the battery 1) obtained from a temperature detecting unit 2. Voltage of a Ni.Cd battery rises gradually with the increase of quantity of charge, but battery temperature is hardly changed till, the battery is charged full. When the battery is charged full, battery voltage achieves a peak value, and thereafter, starts to be lowered by -DELTAV, but battery temperature rises continuously. Namely, at the time of full charge of the Ni.Cd battery, in the case where a temperature rise value, which has been continued for a fixed time, is less than a specified value, charge is continued.
