IPC: H03K5/153
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To generate a pulse signal having fixed pulse width independently of power voltage by charging a capacitor with a constant current responding to a control signal, comparing charged voltage in the capacitor with reference voltage, and outputting a pulse signal based on the compared result. SOLUTION: A switch circuit 13 is turned ON when an input signal IN is H level.

Charged voltage in the capacitor 12 is compared with reference voltage Vref, the compared result is reversed by an inverter 16, and an output signal OUT is obtained. As an output current value from a constant current source circuit 14 is always constant independently of a value of power source voltage VDD, charged voltage of the capacitor 12 exceeds reference voltage Vref after a fixed time whenever an input signal IN is supplied, a pulse signal OUT of fixed pulse width is outputted from the inverter 16.

Title: Method and device for automatically detecting end point of dissolution of metal
Inventor: YOSHIKAWA HIROYASU
IPC: G01N31/12
Filed: 1992-12-18
Abstract: PURPOSE:To automate metal analysis and to speed it up by automatically detecting the end point of dissolution of metal. CONSTITUTION:Light is applied to a solution in a transparent container 2 for dissolution to optically capture the changes in transmission light and scattered light by light receptors 41 and 41 and to judge a reaction end point by an operator 5. The change in transmission light is the one for increased retrieval by the reaction end which occurs after the decrease in transmission light due to generation of hydrogen accompanied by the dissolution of a metal sample 1 and the one due to absorption of light with a specific wavelength of a dissolution reaction product. The change in the scattered light is the one for retrieving phenomenon by the end of dissolution reaction which occurs after the increase in the scattered light due to generation of hydrogen. Therefore, sample dissolution and quantitative analysis can be continuously automated, thus saving time after dissolution is completed. Also, the solution samples of a plurality of metal seeds can be simultaneously sampled.
