Title: Magnetic disk device
Inventor: TAKEDA TAKAYUKI
IPC: G11B20/00
Filed: 1989-06-09
Abstract: PURPOSE:To shorten the access time and to promote the throughput of the access by providing the magnetic disk device with plural seek mechanisms and providing a recording and reproducing circuit, a modulation/demodulation circuit and a control circuit to each seek mechanism. CONSTITUTION:Data is read and written on a recording magnetic layer on the surface of a disk medium 1 by magnetic heads 3-1, 3-2 and 3-3. These magnetic heads are fitted with the seek mechanisms 5-1, 5-2 and 5-3, each being capable of accessing a prescribed cylinder by moving a needle of the seek mechanism. Then, access can simultaneously be performed up to three places, thus shortening the waiting time for revolving the medium 1. In addition, if the individual seek mechanisms are disposed in advance on an outer circumference, in the middle and on an inner circumference of the medium 1, the seek time can also be shortened. By this method, the access time is shortened, and the throughput is promoted.

Filed: 1988-06-13
Abstract: PURPOSE:To reduce the shrinkage of a fluorocarbon resin sheet by applying pressure to the fluorocarbon resin sheet at a position in the vicinity of the end part of a heat generator at an arbitrary time several sec before or after the supply of a current to the heat generator is cut off. CONSTITUTION:An object to be welded is set on a plate 5' and a heat generator 3', and a main cylinder 2 is allowed to fall on the object to be welded and a current is supplied to the heat generator 3 provided to the leading end of said cylinder 2 and the heat generator 3' to perform welding. At this time, the heat generators 3, 3' and the object to be welded generate thermal expansion and elongation of several mm is generated. When the supply of a current is cut off, heat-shrinkage is started in the heat generators 3, 3' and the welded surfaces of the object to be welded to appear as contraction. Therefore, at an arbitrary time (different according to the melting/welding temp. and thickness of the object to be welded) several sec before or after the supply of a current to the heat generators 3, 3', the side cylinders 4 mounted to both sides of a frame 1 are allowed to fall and the object to be welded is fixed by the plate 5 mounted to the leading ends of said cylinders 4 and the plate 5' to be cooled as it is and, thereafter, the main cylinder 2 and the side cylinders 4 are raised. By this processing method, contraction is suppressed to the min.

IPC: H05K3/00
Filed: 1988-06-15
Abstract: PURPOSE:To increase an alignment accuracy of a solder resist and to prevent the resist from hanging in a small-diameter via-hole prior to a plating process by irradiating ultraviolet rays onto a surface opposite to a surface on which an ultraviolet-ray cured plating and soldering resist is applied. CONSTITUTION:An ultraviolet-ray cured plating and solder resist film 5 is applied to the whole surface of one face of a printed wiring board. A through- hole portion is masked from the other face of the board. Then, ultraviolet rays is irradiated from the masked face and an uncured portion of the resist film 5 is removed by using a solvent such as a chlorothane. In the same manner, the resist film 5 is formed on a face opposite to the face on which the resist film is formed and a thick copper plating film 8 is formed on a conductive portion not coated with the resist film 5. Then, a thermosetting solder resist is applied to the whole surface. By this method, a very accurate resist can be formed. Therefore, the resist hanging in the through-hole before a thick chemical copper plating process is prevented from remaining and a high reliability can be achieved.
