Filed: 1985-11-11
Abstract: PURPOSE:To obtain the plasma treatment device capable of the uniform treatment of plural samples at the same time by making a high-density plasma pass over the plane to be treated while drawing an arc. CONSTITUTION:Wafers 20 are arranged on separate positions on an electrode 10 and the planes of wafers 20 to be treated are etched by a plasma 40 produced by discharge of a high-frequency power source 30 and a magnet component 60 rotated by a rotating means 50 is arranged under the electrode 10. In the magnet component 60, two pairs of permanent magnets 62(S-pole), 63(N-pole), and 64(N-pole), 65(S-pole) are arranged with their magnetic poles directed to opposite directions mutually on a disc 61 composed of a ferromagnetic member while forming spiral curves from the center of the disc 61 toward the peripheral part. A rotating angle for making a high-density plasma pass, that is, the time necessary for that is reduced gradually to be in inverse proportion to an etching rate R, according to the distance from the center of the rotation of the high density plasma forming a spiral curve. Thus, the generation of a dust can be restrained and the treatment under clean condition can be attained.

IPC: B41F13/24
Filed: 1988-10-06
Abstract: PURPOSE:To secure an appropriate gap for paper thickness and thereby increase the quality of printed matter by axially supporting an impression cylinder for printing the verso which comes in contact with a rubber cylinder for printing the verso and an impression cylinder for printing the recto with a gap provided in between and the rubber cylinder for printing the verso, using an eccentric bearing with the eccentrically arranged centers of a shaft of a inner bearing peripheral circle and an outer support peripheral circle, connecting the outer peripheral sections of these two eccentric bearings with a connecting member and also coupling a rotary operation member to one of the eccentric bearings. CONSTITUTION:If a knob 29 is rotated when the thickness of paper 7 changes, an operation rod 27 moves backward due to a screw action to rotate an eccentric bearing 13. Consequently, a rubber cylinder for printing the verso 14 moves,so that a gap T between the rubber cylinder for printing the verso 14 and an impression cylinder for printing the verso 16 is adjusted to the thickness of paper. In addition, due to the rotation of an eccentric bearing 13, an eccentric bearing 15 connected with the eccentric bearing 13 using a rod 26 rotates, and subsequently, the eccentric action of the eccentric bearing 15 causes the impression cylinder for printing the verso 16 to move. This action, in turn, results in the adjustment of a gap T1 between the impression cylinder for printing the verso 16 and an impression cylinder for printing the recto 18 to the thickness of paper. That is, the adjustment of the gap T1 is interlocked to the adjustment of the gap T.

Filed: 1986-10-24
Abstract: PURPOSE:To control the driving ability of the output MOSFET of an output buffer in test operation, etc., with a specific control signal by using plural output MOSFETs which are formed in a parallel configuration by connecting their sources and drains in common. CONSTITUTION:A couple of output MOSFETs Q7 and Q17 are controlled to turn on and off according to only an internal signal d1 regardless of an internal control signal tc which is held at a high level in a function test. Further, other three couples of output MOSFETs Q8, Q18 - Q10 and Q20 are all turned on together according to the internal signal d1 wen the internal control signal tc is held at the low level, i.e. in a normal operation state. When the internal control signal tc is at a high level, i.e. in the function test state, on the other hand, they are held off although the internal signal (d) is '1'. Consequently, voltage variation is reducible and an accurate function test is taken even in case of such a test pattern that output signals are all held at logic '1' or '0' together.
