IPC: H04L9/08
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To decode ciphered data by using a cryptographic key communicated asynchronously with the ciphered data. SOLUTION: In a step S16, a control circuit monitors an ODD/EVEN flag added to encryption data. In a step S17, the control circuit decides whether the flag read in the step S16 differs from a flag read last time, and when the control circuit decides that the flag is changed, the processing continues to a step S18. In the stop S18, the control circuit discriminates whether the new flag is an ODD flag or an EVEN flag, and when the control circuit decides that the new flag is the ODD flag, and the processing continues to a step S19. The control circuit in the step S19 decides whether a key smaller in two keys described in a register is recorded in an EVEN register, and when the control circuit discriminates that the smaller value key is described in the EVEN register, the processing continues to a step S20.  The control circuit in the step S20 causes the EVEN key described in the EVEN register to be updated.

The spindle 20 has a measuring range (a), and if the dimension to be measured lies within the range between a+b+c and b+c, it is possible to use the micrometer 10 with no help of any accessory component. If however the measuring range is between (c) and a+c, an extension standard gauge 30 is attached to the spindle 20 with the aid of a sleeve 40, which causes the measuring range to be between (c) and a+c. An appropriate one of the standard gauges 26, 28, 30 is applied to the sleeve 40 for constituting the measuring gap having different length.

IPC: H04L29/06
Filed: 1984-07-03
Abstract: PURPOSE:To send protocol kind information to a terminating exchange even through a packet switching network different in specification by adding and setting the protocol kind of an originating subscriber in a subscriber number by an originating exchange, and informing the terminating exchange of it. CONSTITUTION:For example, a subscriber T1 has a subscriber number SN1 of ''54321'' and a subscriber T2 has a subscriber number SN2 of ''56789''. When the subscriber T1 as an originating subscriber has a communication with the subscriber T2 as a terminating subscriber, the subscriber T1 sends the subscriber number SN2 of the subscriber T2 to an exchange SW1 for call setting. The exchange SW1 sets the protocol kind code of the originating subscriber T1 to the digit ''#'' of ''54321#'' as a subscriber number SN3 for interoffice transfer and it is transmitted to an exchange SW2 together with the subscriber number SN2 of the subscriber T2. The exchange SW2 identifies the protocol kind code of the subscriber T1 from the ''#'' of the originating subscriber number SN3 for interoffice transfer.

IPC: G02F1/136
Filed: 1991-06-10
Abstract: PURPOSE:To decrease the generation rate of the defects generated by metal residues and fine particles, etc., during the production process by connecting the lower metallic layers of nonlinear resistance elements to data lines at plural points. CONSTITUTION:The lower metallic layers 12 of the nonlinear resistance elements 16 are connected to the plural data lines 11 running in parallel so as to hold picture elements 15 at the plural connecting points 11a, 11b. Since these data lines 11 and the connecting points 11a, 11b are provided apart to hold the picture elements 15 therebetween, the probability that the presence of the metal residues and fine particles destroying a part of the data lines 11 leads to the destruction of the elements 16 is lowered. The data lines are plural with one array of the picture elements and the leader lines from the data lines 11 to the metallic layers 12 are plural and, therefore, even if any one data line or any one leader line is broken by the metal residues and fine particles, the other leader line is usable and the supply of the driving voltage of the elements 16 is not hindered.

IPC: B60L13/03
Filed: 1989-05-30
Abstract: PURPOSE:To reduce the time required for deceleration by reducing the speed by a mechanical brake to a designated transport speed or to a designated position, and thereafter reducing the speed by a linear motor until stopping in the above apparatus of a production line. CONSTITUTION:In case of reduction the transport speed or stopping, a controller 32 operates a mechanical brake means 24 through a hydraulic control circuit 33 to suddenly decrease the speed in a short time. When the transport speed becomes a designated speed, or when it reaches a designated position between work stations, the mechanical brake means 24 is turned off, and a deceleration preset value for deceleration by a linear motor is computed. According to the arithmetic results, an electric current applied to linear motor coils 10 are switched to decrease the speed.
