Title: Control method for gyrotron power source
Inventor: UEDA KAZUHIRO
IPC: H01J23/34
Filed: 1985-04-12
Abstract: PURPOSE:To enable to rise an anode voltage rapidly as well as to prevent a drop of the beam voltage, by giving a wave form with an exponental or functional rise to a reference voltage to determine the starting of the anode voltage. CONSTITUTION:Since C1>>C2, and R3>>R4 in the grid voltage control coil (see the figure) of a beam voltage control tube V1, the constant when the grid voltage is converted is  R3.C2 (normally 0.5 to 1.0ms), and the voltage cannot coverted then faster than the constant, even though a voltage rise command inputs. The tube current to the grid voltage rises gradually when the grid bias is deep, but it rises linearly when the grid bias comes to be deeper to a certain value. During this gradual variation, if only a load current rises, the tube voltage will rise to compensate a shortage of the tube current. In order to prevent an increase of the load current more than the tube current while the grid voltage rises, a command to convert gradually in the former half and rapidly in the latter half, shown s figures a and b, is given to control the rise of the anode voltage.

Abstract: PURPOSE:To enable a reinforced seamless film to be efficiently manufactured by rocking a needle roll to the lateral direction of the film, which is pierced into the film from the slit of a guide member, and thereby forming splits continuously in the lateral direction. CONSTITUTION:A guide member 1 and a needle roll 17 are rotated to the same direction with the same circumferential speed with a motor 7 operated, and a transfer belt 2 follows the guide member 1 so as to be rotated. Simultaneously, a crank mechanism 27 allows the needle roll 17 to be reciprocated to the axial direction against the guide member 1. In this place, when a plastic film is forwarded between the guide member 1 and the belt 2, the film F is moved from the top to the front while the both ends of the film is being held between the grasping section 1a of the guide member and the belt 2. During the period of the time, the needle 18 of the roll 17 is projected out of a slit 1b with the rotation so as to be pierced into the film F for allowing the film F to be split by the movement in the axial direction so that the needle is drawn back into the slit 1b again thereafter. Splits can thereby be formed in the lateral direction of the film F by repeating the abovesaid operations.
