Abstract: PROBLEM TO BE SOLVED: To prevent illegal copy of information. SOLUTION: An EEPROM 27 of a DVD player 1 as a source stores a hash function and a service- key. An EEPROM 50 of a personal computer 2 as a sink stores the ID and license0 key. A DVD player 1 requests an ID from the personal computer 2 (S1). At the time of receiving the ID, the DVD player 1 applies a hash function to data (ID ||service- key) obtained by connecting the ID with the service- key, and obtains a key lk. Moreover, the DVD player 1 generates a cryptographic key (sk), and transmits data (e) obtained by enciphering with the key (lk) as a key to the personal computer 2 (S8). The personal computer 2 decodes the encoded data (e) by using the license- key as a key, and obtains a cryptographic key (sk') equal to the cryptographic key (sk).

Title: State storage circuit
Inventor: YAMAMURA TAKESHI
IPC: H03K3/037
Filed: 1993-08-23
Abstract: PURPOSE:To enable the state storage circuit from exiting from an unstable intermediate level state. CONSTITUTION:The circuit has cross-coupled logic elements 42 and 43 which sample an input signal D with a write control signal C and hold the logical state Q. A delay circuit 46 outputs the delay signal C' generated by delaying write control C by a specific time. This delay signal C' is applied to the gate of an N type transistor(TR) 42-1 included in an inverter 42. Namely, when the delay signal C' is at level H, the N type TR 42-1 has state transition in the ON direction, so the logical threshold value of the inverter 42 shifts to a lower voltage (Th1), and when the delay signal C' is at level L, on the other hand, the N type TR 42-1 turns OFF to shift the logical threshold value of the inverter 42 to a higher voltage (Th2) through the operation of a P type TR 42-2.

Title: Ultrasonic vortex flowmeter
Inventor: INADA YUTAKA
IPC: G01F1/32
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic vortex flowmeter the power consumption of which can be reduced pertinently. SOLUTION: An ultrasonic vortex flow meter is provided with a driver 22 which causes an ultrasonic transmitter 3 to intermittently radiate ultrasonic waves and a driving interval controller 24 which makes the driving interval of the driver 22 longer when the signal from a flow rate-voltage converter 25, namely, the flow rate of a fluid is small. Since the driving interval of the transmitter 3 by means of the driver 22 becomes longer when the flow rate of the fluid is small, the electric power consumed for radiating the ultrasonic waves becomes smaller and, the power consumption of the flowmeter is suppressed by the reduced amount of the electric power.  Since the power consumption is reduced by controlling the driving interval of the transmitter 3, the circuit configuration of the flowmeter becomes simpler as compared with the prior art in which the power consumption is suppressed by lowering the oscillating level of ultrasonic waves, because the high-magnification gain circuit which is required for the prior art becomes unnecessary, and, therefore, received ultrasonic signals can be processed easily.
