Title: Magnetic disk package body and packaging method
Inventor: ODA TAKEHIKO
IPC: B65D85/00
Filed: 1989-03-09
Abstract: PURPOSE:To preclude dew condensation due to severe variation of outside environment by forming the package body, which is formed by loading magnetic disks in a caddie and sealing the caddie with a package material, and then charging N gas of atmospheric pressure in a caddie and between a caddie and package material. CONSTITUTION:The disk package body 20 is so formed that the atmospheres between SA a laminate sheet 5 and the caddie 10 and in the caddie SC are N gas atmospheres of atmospheric pressure. Further, the package body 10 has a desicating agent 4, such as a silica gel, fitted on the outside surface side of the caddie. The part SB between a laminate sheet 6 for 2nd packaging and the sheet 5, on the other hand, is reduced in pressure to, for example, about 400mmHg as usual. Then when the sheet 6 is opened for unpackaging, ambient dirt may be sucked by the internal pressure reduction, but the sucked dirt is cut off by the sheet 5 and does not reach the caddie 10. Then when the sheet 5 is opened, no dirt is sucked because the atmospheric pressure is held inside the sheet 5. Further, no dew condensation due to outside air variation is caused because the N gas atmosphere is produced inside the sheet 5.

Title: Frame transfer system
Inventor: HIROZAWA MAKOTO
Filed: 1988-03-11
Abstract: PURPOSE:To omit the need to recognize a fact that a terminal of the remote side has moved to another information communication network and also to evade the reduction of communication capacity due to the movement of the terminal by performing the communication with a terminal that moved via a transfer server in case the terminal has the temporary movement. CONSTITUTION:A transfer server TSi (1<=i<=4) belongs to an information network Ni and contains a transfer table TTi, a CPU 31, a buffer 32 and a communication control part 33. The reception of information from the network Ni is informed and a rewriting instruction is delivered for the address of a moved terminal via a communication control part 33. While the frame transmitted to terminal that moved temporarily to another network Ni is stored temporarily in the buffer 32. Then the table TTi performs the service to transfer the information to the destination network Ni. Then the transfer servers TS1-TS4 perform the service to allocate the addresses to the terminals (the address server function). Thus the communication is possible with the terminal of the remote side without recognizing a fact that said terminal has moved to another information network.

Abstract: PURPOSE:To prevent image change during retention copying by providing a rotating body with a latent image forming means, a memory means for detecting and processing the electric state of the body and retaining it for time of one rotation of the body, and a memory means for again detecting it after one rotation. CONSTITUTION:When a screen 29 is used in a grounded state, and a modulating corona ion current is generated from a corona discharger 26, a part of it flows to a shielding plate 28, another part flows to the screen 29, and the rest passes through the screen 29. This ion current flows to the recording medium 30 to which voltage is applied from a bias power supply between the screen 29 and the medium 30, and a secondary electrostatic latent image is formed on the surface of the medium 30. The current flowing through the resistor 35 becomes only the amt. of current passing through the screen 29. A current acting for actually forming the secondary electrostatic latent image can be measured by measuring the potential of the resistor 35. As a result, image change during retention copying actuating only a step following the formation of the secondary electrostatic latent image can be prevented.
