Title: Method and apparatus for carrying out plasma treatment
Inventor: FUKUDA KENJI
IPC: H01J37/32
Filed: 1983-03-10
Abstract: PURPOSE:To improve a plasma treating effect, by carrying out a plasma treatment while rotatably moving a plurality of materials to be treated in correlation to one another and independently rotating them. CONSTITUTION:When a rotating moving shaft 16 is rotated by driving a motor 27, the vertical disk surfaces 19-1 and 19-2 of a truck for receiving jigs are rotatably moved and at the same time shafts 17-1-17-4 supporting materials S-1-S-4 to be treated are rotatably moved while each of said shafts draws a circular locus 20. During the course of this rotating movement, the arranging directions of the materials S--S-4 to be treated are corrected around free rotating shafts 17-1-17-4. When an extending shaft 23 is interlocked with a junction means 24, rails 30-1-30-2 are lowered through an air cylinder 29 to a position at which they do not interface with the rotation of the vertical disks 19-1, 2 of the truck for receiving jigs. The door 21-1 of a treating container 1 is then closed to start a series of plasma treating operations.

Title: Optical receiving circuit
Inventor: KAJIYA SATORU
IPC: H04B10/572
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a signal becomes small under the condition that the level of a level detecting means becomes constant in a noisy state by providing a selecting means which selects one of gain control systems and switching the gain control systems of a variable-gain optical amplifier. SOLUTION: A selecting means 12 compares the output of a clock extraction level detecting means 7 with the output of a data level detecting means 6 to decide which one has a large value. According to the decision result, the selecting means 12 selects a signal having the large value and supplies it to the variable-gain amplifier 1 via a gain control means 13. Thus, the variable-gain optical amplifier 1 is so controlled that the signal having the large value between those outputs reaches a certain constant value, so that when the duty of an RZ signal is in the vicinity of 50%, the output amplitude of the clock extracting means 7 has the specific value, so that when the duty ratio is much different from 50%, the output signal of the data level detecting means 6 becomes constant.

Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To purify lakes and marshes in low cost in an energy saving manner by a small amt. of treated water. SOLUTION: A water gathering pipe 12 is arranged to an eutrophic salt water layer preliminarily investigated and determined in its specific range part.

Title: Method for reducing artifact of high speed nuclear magnetic image diagnostic apparatus
Inventor: MIURA NOBUYUKI
IPC: G01R33/48
Filed: 1988-02-22
Abstract: PURPOSE:To prevent an artifact such as shading without applying a new magnetic field by applying a phase encode gradient for changing the amplitude of each view at random to a warp axis. CONSTITUTION:When the amplitude of a warp gradient is successively changed corresponding to view order, shading is generated. Therefore, a random warp gradient 1 is applied. In the change of this warp, a broken line is a curve 11 showing warp reaching -MAX +MAX of conventional warp order and a solid line is a curve 12 showing one embodiment of this random warp order. As mentioned above, if the warp order is selected at random, even when the magnitude of the warp in certain view of this random warp order is a value in the vicinity of 0, since the warp quantities of the previous view and the further previous view are in a large state, by performing scanning by selecting warp order at random, the residual echo is not added to the original echo because of the spoiler gradient of a warp gradient and shading can be prevented.

Abstract: PURPOSE: To reduce the influence of the sliding noise by a magnetic tape in a magnetic head for 8mm VTR device, etc. CONSTITUTION: In the core 1 of the magnetic head H, a part on the more tip side than a stopped part 1a is made to be a thin wall part 1b.

Moreover, a frequency in which the peak of the tape sliding noise appears can be shifted to the higher frequency side in which the influence to a video carrier signal is small. Thus, the flicker of a reproduced picture is prevented from occurring.
