Title: Gas laser device
Inventor: MORI ATSUSHI
IPC: H01S3/134
Filed: 1987-05-20
Abstract: PURPOSE:To hold the pressure of a laser gas accurately for a prolonged term by measuring gas pressure in a laser tube by a pressure sensor, comparing the gas pressure with a preset set value by a pressure setting means and controlling a gas laser device so that a deviation between the gas pressure and the set value is brought to zero. CONSTITUTION:Gas pressure required for a laser output needed for specified processing is set to a pressure setting means 15. The pressure of a laser tube 3a is measured by a pressure sensor 6, and transmitted over an AD converter 11 as an analog voltage value. The AD converter 11 converts the analog value into a digital value, and transmits it over a gas pressure control means. The gas pressure control means compares a set value and a measured value, and outputs a signal, through which a deviation between both values is brought to zero, as a digital value. The output signal is converted into an analog output signal by a DA converter 13, and transmitted over a driver 14. The driver 14 changes the analog value into a current value proportional to an input, and controls the opening of a variable control valve 2. Accordingly, gas pressure in the laser tube is kept constant.

Title: Device for controlling plural elements to be operated
Inventor: BAN ITSUKI
IPC: G05B19/02
Filed: 1980-09-09
Abstract: PURPOSE:To perform plural operations independently by selecting one of driven elements, engaging with a cam when the cam is in reverse motion, by turning the cam normally and by driving it by reversing the cam. CONSTITUTION:A cam 20 turns normally colockwise. As an input signal is supplied, the output of an unshown detector stops the cam at a position corresponding to the input signal and then the cam reverses counterclockwise. For example, if a following element 7-1 stops at the position of a cam recess part 25, the cam 20 reverses to insert the following element 7-1 into a groove 23 and a lever 2 is pushed up through the operation of a crank 7. A lever 2 performs prescribed operation and a pawl 2-1 engages with a locking piece 6-2, which is held. As a release signal is inputted, the cam 20 turns clockwise and a locking lever 6 moves to left through a lever 5 to disengage the pawl 2-1 and locking piece 6-2 from each other.

Abstract: PURPOSE: To make the measurements stable and accurate for a long time by using a solution of KNO 3  as an electrolyte in a chemical oxygen demand meter for measuring the potential between two liquids while gradually feeding the electrolyte through a liquid communication portion of a slat bridge to a portion to be measured.  
     CONSTITUTION: A reservoir tank 3, which reserves electrolyte and into which a silver-silver halide electrode 1 is dipped, and a reaction container 4, which reserves a liquid to be measured and into which a platinum electrode 2 is dipped, are made to have communication through a salt bridge 5, which has its lower end portion equipped with a liquid communicating portion 6, thus constituting a chemical oxygen demand (COD) meter. As the aforementioned electrolyte, the conventional solution of KCl is replaced by the solution of KNO 3 . Since the liquid communicating portion 6 is made by embedding pin hole or poroud ceramics, clogging is liable to take place. By using the solution of KNO 3  as the electrolyte, no clogging takes place for a period longer than three monthes so that the stable measurements can be accomplished.
