Title: Magnetic disk medium
Inventor: NAKAJIMA MINORU
IPC: G11B5/70
Filed: 1989-03-15
Abstract: PURPOSE:To obtain the magnetic disk medium which has no possibility of impairing the floating stability of a magnetic head by unifying the grain size of the nonmagnetic powders to be added to a magnetic coating compd. within a prescribed range with respect to a coated film thickness. CONSTITUTION:All of the nonmagnetic powders to be added to the medium of a coated film type constituted by applying the magnetic coating compd. consisting of magnetic powder, nonmagnetic powder and resin on a nonmagnetic substrate have the grain sizes within the + or -20% range of the coated film thickness. Since the coated film thickness is usually about 0.5mum, the use is possible up to about 20% of the coated film thickness converted in per centage if the projections within 0.1mum are assumed to be permitted. If there is the nonmagnetic powder 5a extremely finer than the coated film thickness, the resin weaker in the strength having the thickness (d) exists between the substrate 1 and the surface of the coated film and, therefore, there is no effect of improving the strength of the coated film. The strengthening of the coated film is possible if the resin thickness (d) is within about 0.1mum. The sure strengthening of the coated film is, therefore, enabled by this constitution and there is no possibility of impairing the floating stability.

Title: Exposing method for photoresist
Inventor: HAYASHI SHUNICHI
IPC: G03F1/00
Filed: 1988-03-15
Abstract: PURPOSE:To easily shorten exposure time even when an exposer such as a parallel exposer is used whose light intensity is weak by performing exposure while heating a substrate where a pattern is to be formed. CONSTITUTION:When pattern-shaped exposure is performed on a photoresist laminated on the substrate on which the pattern is to be formed, exposure is performed in a state where the substrate is heated to a temperature higher than a room temperature. The degree of heating should be set in an appropriate temperature range according to the heat stability of the photoresist. Generally, it is desirable that the temperature is >=30 deg.C and <=50 deg.C. Concretely, there are methods of blowing a hot blast to the surface of a photoresist printing frame, constituting the glass plate of a printing frame as double structure and passing a heating medium through it and of pressing a heat plate onto the back side of the substrate. Thus, the exposure time can be shortened even when the parallel exposer is used.

Title: Inter-local area network connecting method
Inventor: HIROME MASASHI
IPC: H04L12/42
Filed: 1989-03-16
Abstract: PURPOSE:To perform supervisory control assuming the branch LAN of a group as one LAN by performing the specific control of a node to which the branch LAN of a skeleton local area network (skeleton LAN) is connected. CONSTITUTION:Data received from a transmission line in current use in the branch LAN 21 is handled in such a way that the transmission destination address of a packet to be transmitted is erased at a reception node by a group address and a transmission origin address is transmitted as the address of its own node 1. A node 3 of group address receiving the packet holds the transmission origin address in the packet, and transmits it to the transmission line in current use of a connection branch LAN 22. Also, the data received from the spare transmission line of the connection branch LAN 22 is transmitted in the packet setting a held transmission origin address as the transmission destination address, and the node 1 receiving the packet transmits it to the spare transmission line of the connection branch LAN 21. Also, when a system is switched where the transmission line in current use of the skeleton LAN 20 is switched to the spare transmission line, the function of the node 1 is performed oppositely to that of the node 3. Thereby, since the branch LAN of the group can be assumed as one LAN, the supervisory control can be performed with one supervisory unit.
