Title: Electrostatic chuck and its manufacture
Inventor: OTANI YOSHIKAZU
IPC: H02N13/00
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent generation of split, warp and crack by forming recessed trenches on a bonding surface to a chuck functional part of a plate part, burying electrodes for high frequency in the recessed trenches, and imparting function as plane electrodes for high frequency to an electrostatic chuck. SOLUTION: A plate part 8 has recessed trenches 15 for burying electrodes 4 for high frequency on a bonding surface of chuck functional part 3 side. Trenches having various kinds of shapes, e.g. trenches wherein a plurality of ring trenches are concentrically formed, spiral trenches, radial trenches, a plurality of linear trenches which run in parallel, meandering trenches, broken line type trenches having the above shapes, etc., can be adopted for the recessed trenches 5. The depth of the trenches is made greater than the thickness of the electrodes 4 for high frequency, and sufficient to prevent the surfaces of the electrodes for high frequency from protruding to a bonding interface.  As a result, an electrostatic chuck can have function of electrodes for high frequency by itself, and generation of split, warp and crack between the chuck fuctional part and the plate part can be remarkably prevented.

IPC: G11B5/09
Filed: 1985-08-14
Abstract: PURPOSE:To join data surely by providing a controller of a streaming type cartridge magnetic tape device with a counter which holds the quantity of written data and updating write data at each time of recording to a cartridge magnetic tape. CONSTITUTION:When accepting a data write command from a central processing unit CPU 1, a cartridge tape device controller CMTC 4 checks whether a CMT RDY flag is turned on or not and fetches the number of times of data transfer designated by the CPU 1 if the flag indicates RDY. It is checked whether the sum of contents of a byte counter and a data counter in the CMTC 4 exceeds a maximum data recording byte number of the cartridge magnetic tape or not. Since the logical tape end position of the cartridge magnetic tape is detected by this discrimination, the CPU 1 can write information, which indicates that data continues to the following cartridge magnetic tape, in the last of the cartridge tape, and the data write operation requiring plural cartridge magnetic tapes is realized surely. Thus, the data are joined surely between tapes without restrictions due to software when the data is recorded.

Abstract: PURPOSE:To make the amount of current variable by providing a spring between a pressure conduction rubber member, whose electric resistance value is decreased as the pressure applied thereto is increased, and a key top portion, which constitutes a push button, and providing two electrodes on the lower surface of the pressure conduction rubber member. CONSTITUTION:A pressure conduction rubber member 2, whose electric resistance decreased as the pressure applied thereto is increased, is provided within a rubber switch cover member 1, and electrodes 4, 5 are provided on the lower surface of the pressure conduction rubber member 2 via a spacer 3, and a lead wire 6 is connected the electrodes. Further, a spiral flat spring 7 is provided on the pressure conduction rubber member 2 with the upper part of the spring 7 facing a key top portion 1A. Accordingly, when the key top portion 1A is pressed gradually, the spring is deformed and presses the pressure conduction rubber member 2 by the lower surface of the spring. When the pressure applied to the key top portion 1A is increased, the pressure applied to the pressure conduction rubber member 2 from the spring is also increased so that the pressure conduction rubber member 2 is brought into contact with the electrode 4, 5 while it is pressed. Thus, the resistance of the pressure conduction rubber member can be varied according to the amount of pressure, hence the amount of current is made variable.
