Title: Method and system for loop communication
Inventor: HINO YUSUKE
IPC: H04L12/46
Filed: 1986-05-23
Granted: 1990-09-25
Abstract: A loop communication network consists of a number of loop paths which are interconnected through loop coupling devices. Each loop communication path has at least two message terminals, one of which sends a message including routing information, the address of a destination loop coupling device, and sending address, and another of which sends and receives message without routing information. Each loop coupling device responds to routing information messages and controls the transfer of other messages between different communication loop paths which are connected to it. Routing information is stored in the loop coupling device for use in routing of return messages.

Title: Laser drum of optical-megnetic tape
Inventor: CHUNG SUNG-TAE
IPC: G11B15/61
Filed: 1986-06-07
Granted: 1990-07-08
Abstract: The laser drum for reading and recording the data with the light comprises an upper drum (1) with light holes (3,3') and a lower drum (2) with a tape guide line (4). In the upper drum, semiconductor lasers (10,10'), a full reflective prism (11), diffractive grates (13,13'), light dividers (14,14'), objective lenses (15,15'), polarizing plates (18,18'), light detectors (19, 19'), and an upper transformer (32) are contained. In the lower drum, a lower transformer (33) is contained. The motor (6) placed under the lower drum rotates the drum with a certain incline angle.
