Title: Inspection method of magnetron
Inventor: ASO TOSHIYUKI
IPC: H01J23/36
Filed: 1990-01-24
Abstract: PURPOSE:To perform a precise inspection of magnetrons by changing the position of a variable short-circuit plate according to the height of the high frequency outputting part to keep the voltage standing wave ratio in a satisfactory state of less than 1.1 within the maximum output setting area. CONSTITUTION:In the case of characteristic measurement of a standard magnetron having a high frequency output part, the opening part vertical size can be held constant by a positioning jig 9. In the case of characteristic measurement of a flat magnetron having a short high frequency output part, a short-circuit plate 7 in a high frequency coupler is lowered, and the vertical size 5a of the opening part is changed to provide a function equal to a coupler for flat tube only. As the short-circuit plate 7 is held in the lowered state by the upper stopper jig 9 of a shaft 10, the maximum output area is extended to the point of a voltage standing wave ratio less than 1.1. Hence, the size of the set area can be made equal to that of a standard tube, resulting in no erroneous operation of sensor and a precise inspection.

Abstract: PURPOSE:To plasticize a molding material in a short time and suppress wear of a screw and cylinder, by a method wherein the molding material is plasticized while resonating the whole or/a part of a screw and/or a cylinder, especially performing n-wavelength resonance with an ultrasonic wave. CONSTITUTION:A cylinder 1 is provided with a hopper 8 on its left end part and a molding material such as thermoplastic plastic is fed into an insertion hole 9 of the cylinder 1 from the hopper 8. The fed molding material is moved rightward on an illustration while it is being plasticized by a rotating screw 2 and resonating cylinder 1 and discharged outside through an outflow port 10 under a plasticized state. The hopper 8 of a loading port of the molding material is designed so that its resonance frequency becomes the same with that of the cylinder 1 during molding as much as possible and it is preferable to fit to a position other than a joint part of a displacement wave form L, that is, a vibrating position of the cylinder 1. With this construction, since the hopper 8 also can be resonated along with the cylinder 1, generation of a bridging phenomenon on the molding material within the hopper 8 is prevented and feed of the material can be performed smooth.

Filed: 1978-02-09
Abstract: PURPOSE:Control unit drives hydraulic cylinder to operate a pair of vertical rolls to provide either a constant rolling thickness or a constant rolling pressure. This constructional mechanism provides a compact, high-accuracy, vertical rolling mill. CONSTITUTION:First, a rolling steel plate 1 is relatively thick and substanially constant in width and has a property such that little buckling or local swelling may be caused. When rolling such material, an extension is detected on the piston rod 11c installed on the hydraulic cylinder 11, then the oil drive unit is actuated so as to eliminate the deviation between the preset signal and the signal of the position detector 12 which detects the vertical rolling gap by detecting the extension of the piston rod 11c. Secondly, when rolling a steel material having contrary properties, the oil drive unit is actuated to eliminate the deviation between the preset signal and the signal of the pressure detector 13 which detects a vertical rolling pressure by detecting hydraulic pressure of back pressure chamber at extension side of the hydraulic cylinder 11. Thus, a pair of vertical rolls 8,8' maintains the preset pressure for rolling operation.

Abstract: PURPOSE:To obtain a silver dioxide battery which effectively removes O2 gas and thereby improve the increase of discharging capacity and the decrease of initial resistance of a battery, by using the negative electrode system made of a partially gelled surface of zinc grain to the positive electrode system mainly composed of silver dioxide. CONSTITUTION:A positive mixture mainly composed of divalent silver oxide is pressed into a metal case 1 in order to pack it. A separator 3 is disposed on the metal case 1, and an insulated gasket 4 whose cross section is L-shaped is fitted to on the upper part of the separator 3.

Thus, said O2 gas is effectively removed and thereby the expansion and the bursting can be surely prevented.
