Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for judging the retrial of transmis sion to an electronic price label(EPL). SOLUTION: This system and method are especially related to judge the retrial frequency of transmission of an EPL data message to an EPL 18 in an EPL system. Transmitters 12, 10 transmit a data message to each EPL 18. Receivers 12, 16 receive a return signal from each EPL 18. A storing system 28 stores a status flag expressing 1st frequency for transmitting a data message from the transmitter to the EPL 18 based upon the ratio (S/N) of an established signal to noise. A communication base station(CBS) 10 judges a new S/N obtained from a return signal. An execution time analyzer program 26 judges whether the new S/N is less than an S/N range including the established S/N or not, and when the new S/N is less than the range, presents a new status flag expressing 2nd transmission frequency more than the 1st transmission frequency.  The transmitters 12, 16 transmit a succeeding data message by the 2nd frequency.

IPC: G05F1/10
Filed: 1989-06-12
Abstract: PURPOSE: To maintain power consumption to be constant, by generating a feedback current corresponding to a current flowing through a resistor and a correction current corresponding to the change of a supply voltage, and adjusting the power consumption by an error signal designated by the above currents. CONSTITUTION: Instead of the feedback of a signal proportional to an effective value current flowing through the resistor 34 of a heater, a correction current is generated on the basis of the change of a supply voltage by a correction circuit 55. This circuit generates the correction current, and its resistor 56 is coupled with a supply voltage and generates a variable current 13 changing with the change of the supply voltage. A resistor 58 is coupled with an effective value reference voltage, and the resistors 36, 54 and the like form a generating means of a feedback current I1. When a DC supply voltage is lower than or equal to a nominal value, a variable current I3 is smaller than a second reference current I2. As a result, the average current (current I1) of the heater so acts that a control loop maintains a stationary state, and increases.

Title: Mti device using optical fiber delay line
Inventor: TAKEUCHI YASUTO
IPC: A61B8/06
Filed: 1989-06-14
Abstract: PURPOSE:To easily control the delay time with a simplified circuit by providing a means, in which a delayed sampling signal is produced by circulating the sampling signal of echo signal in a delay line, and a means which extracts this delayed sampling signal to be output. CONSTITUTION:An echo signal is fed to an optical fiber delay line 4 in the shape of an analog sample value of coherent light from an amplifier 2 and a laser diode 3 through an echo terminal in an RCSW1 by a controller and output to flow in a low pass filter 8 from an amplifier 6 via a photodiode 5 while transmitted to the RCSW1 to flow in an inversion amplifier 7 with the polarity inverted. Here because the RCSW1 is switched to a circulation terminal by the controller, the signal is recirculated, and the pattern is repeated before reaching the predetermined time (in this case, 1muS). Since the RCSW1 is switched to an echo terminal, a sample of the echo signal is cut off, and a sample of the new echo signal is input with the similar action repeated.

Title: Charge transfer element
Inventor: FUJISHIMA KAZUYASU
IPC: H01L29/768
Filed: 1978-12-01
Abstract: PURPOSE:To stabilize operation against noises, by providing potential barriers at parts of charge transfer electrodes. CONSTITUTION:p<+>-Layer 8 are provided on parts of a p-type silicon substrate for manufacturing transfer electrodes 4a, 4b. Storage electrodes 3a, 3b are manufactured through an SiO2 film 2. A thick SiO2 film 2a is produced between the electrodes 3a, 3b. The transfer electrodes 4a, 4b are manufactured on the film 2a. The surface potential on the transfer electrodes 4a, 4b is thus made higher than that on the storage electrodes 3a, 3b. As a result, signal charge is prevented by the action of potential barriers from overflowing the storage electrode 3b and mixing with ambient signal charge even if the depth of bottoms of potential wells decrease due to noises. Therefore, the SN ratio does not deteriorate.
