IPC: F16K31/06
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To simplify and miniaturize the configuration of the whole valve to reduce production costs. SOLUTION: When a proportional electromagnetic actuator 14a is energized, a first spool 11 is moved to the left in proportion to the intensity of current, passages between ports P-A, B-Sb, B-Cb are opened, a pressurized liquid flows into one end of a hydraulic cylinder connected to the port A, and discharge liquid from the other end of the cylinder is circulated from the port Cb to a port T through a flow control part formed of a small circular part on the left side of the port B and a spool land 11d. At this time, since the pressure at the port B is connected to a sensing pressure chamber 20a of a pressure compensating valve 20 through the port Sb, and the pressure at the port Cb is connected to a spring chamber 20b respectively, a second spool 21 is moved to the right always to keep the differential pressure across both the ports constant.

Title: Method and mechanism of liquid-removal seal in filling packaging
Inventor: MAEJIMA YOSHIO
IPC: B65B51/10
Filed: 1989-11-13
Abstract: PURPOSE:To prevent foaming phenomenon from taking place by applying heat seal to a temporarily sealed part at a set temperature at a position distant equal to the length of a bag below said part. CONSTITUTION:A cylindrical body R' filled with contents is flattened by holding its opposite surfaces. The opposite surfaces are pressed furthermore against each other in thickness direction so that the liquid N in the body is urged upwardly and downwardly relative to the pressed part and hence both the surfaces are brought into a close contact. And then heat seal is applied to the resins in close contact with each other at a temperature lower than a set temperature and heat seal is applied at the set temperature to a temporarily sealed part distant equal to the length of a bag below said part. Therefore, liquid can be effectively removed from the sealed part. As a result, even when full seal is applied to the temporarily sealed part, foaming phenomenon can be avoided.

Abstract: PURPOSE:To make measurement immediately of the film thickness of a thin film after film formation by a DC sputtering method without affecting on film formation. CONSTITUTION:A controller 9 controls a switch 10 and switches a power source to be supplied to a target 4 to a bias power source 6 for measuring the film thickness by a DC power source 5 for DC sputtering upon lapse of treatment time and controls a UV source 8 to irradiate the substrate 3 formed with films with UV rays, thereby releasing photoelectrons from the substrate surface. The released electrons are captured by the target 4 which is positively biased by the bias power source 6 for measuring the film thickness. An ammeter 7 measures the current passed by the released electrons captured by the target. The controller 9 determines the film thickness based on the previously stored relation between the film thickness and current value by the measured current value. The controller 9 corrects the next treatment time in accordance with the difference between the determined film thickness and the desired film thickness.
