Abstract: A multibeam, electrostatically focused klystron includes a plurality of conductive members, ones of which are recessed to provide input and output sections of microwave cavities, wherein focusing voltage is applied between those sections. The conductive members are either spaced along the path of multiple beams, or stacked in insulated relation, in either case being supported by glass rods within a glass envelope.

Abstract: A method for calibrating a semiconductor test instrument leading cost reduction, simplified work, and short working time. Drivers are related to comparators in one-to-one correspondence. A clock signal and a strobe signal have a one-to-one correspondence. The phase of either a clock signal or a strobe signal is adjusted with reference to the phase of the other signal. The relative phase difference between clock signals or between strobe signals are determined. The phases of the clock and strobe signals are adjusted with reference to the relative phase difference.

Abstract: A massager has a base, a U shaped housing mounted on the base, a motor received in the housing and having a worm shaft extending out of the motor, a transmission assembly encased in the housing and including a transmission axle, a worm gear, two wobbling wheels mounted on the transmission axle and two kneading plates mounted on the transmission axle and a rubbing assembly having two disks respectively mounted on a free end of each of two driven axles and having two rubbing balls formed on a face of each of the disks.

Abstract: The method for fabricating reflector plate for a reflective liquid crystal display and the device is disclosed. The present invention includes the formation of a protection layer over the glass substrate having thin film transistors and a layer of transparent electrodes on top, followed by the formation of a layer of undulating resin over the protection layer. If the reflector plate to be produced is a semi-transmissive type, a light-transmitting region is created over the protection layer. Since the protection layer is created in advance of the undulating resin outgrowth, the present method can effectively prevent reflection from the exposure stage during the lithography process, thus the problem of abnormal pattern marks occurring on the reflective surface can be avoided, and the exposure time and the production yield are enhanced.

Abstract: A developing apparatus prevents magnetic toner rise on the peripheral face of the developing sleeve to avoid scatter of magnetic toner even when a gap is caused between the developing blade and the magnetic sealing member. A magnetic plate of a base part and a protruding part, where the base has a rectangular cross-section and is in the shape of an arc extends along the peripheral face of a developing sleeve. The protruding part is on the upstream side of a doctor blade in the rotation direction in the middle of the base part in the arc length direction. The protruding part protrudes nearly perpendicularly from the side face which is perpendicular to the peripheral face of the developing sleeve, so as to cover the regions of the peripheral face of the developing sleeve from the base part to the portion facing the doctor blade.
