Title: Metallic sheet width rolling-down device
Inventor: ISHII ATSUSHI
IPC: B21B39/14
Filed: 1993-03-30
Abstract: PURPOSE:To which can prevent buckling and temperature ununiformity. CONSTITUTION:A device to roll down the metallic sheet S in the direction of a sheet width through width rolling-down dies 1 arranged face to face on both sides of a pass line L is provided with heating means 7 to heat two sets of pressing plates 5 which make a pair of upper and lower plates arranged face to face on both sides of the pass line. The pressing plates 5 cover the metallic sheet S and heat is refrained by the heat of the heated pressing plate itself from being radiated from the metallic sheet S. Consequently, the width of the metallic sheet S can be rolled down as the metallic sheet is held at a prescrib-temperature. The pressing plates 5 are pressed closely and uniformly in an area necessary to prevent buckling to hinder buckling.

Title: Electron beam blanking device
Inventor: NAKAZAWA HIROYUKI
IPC: H01L21/027
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain an electron beam blanking device which can perform a high-speed blanking of an electron beam. SOLUTION: When blanking of electron beam is performed, a blanking voltage is applied to an anode 9 from a blanking power source 11. A large amount of thermoelectrons from a heater 8 is instantaneously emitted toward the anode 9. The thermoelectrons cross the passage of an electron beam EB from an electron gun 1 on the way to the electrode 9. In this case, since the amount of electrons from the electron gun 1 is remarkably smaller than the amount of thermoelectrons from the heater 8, the electrons form the electron gun 1 are subjected to coulomb force from the group of thermoelectrons from the heater 8, and their speed is reduced to almost a standstill immediately before the group. As a result, the electrons from the electron gun 1 is attracted by the anode 9 together with the thermoelectrons and absorbed by the anode 9.

Title: Protector against thunder surge
Inventor: SONODA MICHIYOSHI
IPC: H01T1/12
Filed: 1991-04-05
Abstract: PURPOSE:To exactly find the replacement timing by detecting the deterioration of a varistor quantitatively and accurately. CONSTITUTION:When a thunder surge impulse is induced in a power system 1a, a surge current flows to the varistor 3 inside a protector 2. If this exceeds the specified current I0, the voltage across the varistor 3 tops the limited voltage V0, and the detection signal of a voltage detector 4 reaches a reference voltage signal b. Hereby, surge detection signals are output from a comparator 5, and those are countered with a counter 6. The counter 6 counts the detection signals c, and counts in up by one count. By repetition of this, if the counter of any phase out of three phases reaches the life limit, it judges that as the deterioration of the varistor 3, and outputs a varistor deterioration signal d. The signal d is sent to a display and an alarm. Even if small energy of thunder surges are applied several times and the varistor deteriorates, since the deterioration can be detected quantitatively, one can find proper replacement timing of the varistor.
