Title: Gas spring delaying in return stroke
Inventor: COTTER JONATHAN P
IPC: F16F9/516
Filed: 2000-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a gas spring for controlling a return speed of a piston rod by using only compressed gas. SOLUTION: A gas spring has a first gas chamber communicated with a second gas chamber via a calibration orifice, and controls a speed for gas to return up to the second chamber from the first chamber to thereby control a speed for a piston rod of a cylinder to return up to the extension position. The speed for the piston rod to return up to the extension position can be sufficiently delayed until a stamped part is not damaged by raising the part from a lower side die by the gas spring. A composite shell of the gas spring is formed of a material having high heat conductivity so as not to overheat the gas spring and so as to increase the cycle number to be completed in a prescribed period, and includes the material.  The gas spring is a complete self- contained shape, resists a movement up to a contraction position of the piston rod by using only gas, offers force for moving the piston rod up to the extension position, and controls the speed for the piston rod to return to the extension position.

Title: Gas discharge lamp monitoring method and device
Inventor: KLINKENBERG KLAUS
IPC: H01J9/44
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To accurately estimate the life and the break of a lamp by generating an alarm signal when a test value relating to clear drop in lamp voltage is detected. SOLUTION: A microprocessor 4 compares a test value from a voltage measuring device for measuring voltage supplied to a UHP gas discharge lamp 1 with an electronic stabilizer 2 with a reference value delayed by an adjustable burn-in phase. An electrical test value is outside voltage proportional to lamp voltage or lighting voltage or supply current reversely proportional to it.
