Title: Secret key generating system
Inventor: TOTSUKA HISAYOSHI
IPC: G06F21/44
Filed: 1991-02-20
Abstract: PURPOSE:To grant the secret keys in a simple way without performing the key control in particular. CONSTITUTION:When a power supply is turned on for registration of the terminals T1-Tn at 8 center A, a random number generating part 1.4 starts to apply the polling to each terminal through the center A and then to assign the time slots so that the UP signals received from the terminals never overlap each other. Therefore the delay measurement control is applied to each terminal. Then the random number value of the part 14 obtained at each terminal when the delay measurement control is complete is defined as a secret key of the relevant terminal. The different types of delay measurement control are always applied to the terminals T1-Tn respectively and therefore the secret keys are proper to each terminal. Based on these secret keys, the open keys and the shared keys are computed at a key computing part 13. The open keys are sent to the center A, and the shared keys are produced from the open keys at the center A.

Title: By-pass switch of polarization plane maintaining optical fiber type
Inventor: MORIZAKI SUMIKO
IPC: G02B6/00
Filed: 1985-02-14
Abstract: PURPOSE:To reserve automatically a by-pass by switching a current flowing to an electromagnet to switch a magnetic field applied to a magnetooptic ele ment and rotating the plane of polarization of linearly polarized light to switch two optical paths after transmission of a polarized light separating element. CONSTITUTION:When a station is broken down, a current I is not present in electromagnets 2-a and 2-b, and a magnetic field is not applied to magnetooptic elements 1-a and 1-b. The linearly polarized light discharged from a polarization plane maintaining optical fiber 4 has not the plane of polarization rotated though it passes the magnetooptic element 1-a, and this light reaches a polarized light separating element 3-a and is led to a polarization plane maintaining optical fiber 7 through the other optical path different from the optical path for the normal operation of the station and passes through a reception end R and a transmission end T and reaches directly a polarized light separating element 3-b. Though it passes the polarized light separating element 3-b and the magnetooptic element 1-b, it has not the plane of polarization rotated. Thus, optical fibers are not moved to switch the optical transmission line, and the by-pass is reserved automatically.

Title: Data transfer system in master slave system
Inventor: OONISHI KENICHI
IPC: G06F12/06
Filed: 1980-03-03
Abstract: PURPOSE:To eliminate excessive busses, by causing the slave CPU to access the main memory by the main memory access instruction, which is read out from the main memory by the command from the master CPU, in the master slave system. CONSTITUTION:In case of data transfer between main memory 22 and internal memory 32 in the slave CPU, instructions including the main memory read instruction and the main memory write instruction for this data transfer stored in main memory 22 are read out to slave CPU21 by master CPU21. Slave CPU21 processes these instructions to access main memory 22 and executs data transfer between main memory 22 and internal memory 32. Consequently, even if the master CPU cannot access the internal memory of the slave CPU directly, the master CPU instructs data transfer between the internal memory of the slave CPU and the main memory without providing excessive address busses and data busses.

Title: Electric sealing heater device for flat type display
Inventor: NAGANOBU HIROBUMI
IPC: H01J9/40
Filed: 1987-02-09
Abstract: PURPOSE:To make a part, which remains after a cutting process, be shorter than flange parts after a sealing process by projecting a glass tube from a side of split flat glass containers with flanges and disposing the glass tube on a position, where the tube is made shorter than the flange parts, and equipping a heater, a heater insulating part, a heat-radiating part, and a heat-shielding part. CONSTITUTION:A flat type displaying device B with flanges ahead of sealing is fixed on a vacuum exhaustion device. A glass tube 6 is made to pass through an electric sealing heater device A and inserted into an exhaustion port of the vacuum exhaustion device. While vacuum exhaustion is performed, the vacuum exhaustion device is heated. In succession while the vacuum exhaustion device is gradually cooled, it is degased, and a cathode is activated or so. While a voltage is applied to a heater 4 in the electric sealing heater device A, the glass tube 6 is heated, melted, sealed, gradually cooled, and then the flat type displaying device B is released from the vacuum state and extracted from the vacuum exhaustion device, and a sealing part of the glass tube 6 is cut at its central position. Since the electric sealing heater device A is thus equipped with a heat-radiating part 2 and a heat-shielding part 5, a part which remains after a cutting process can be made shorter than flanges 9 and 9 without exerting bad effects on glass containers 11 and 11.
