Title: Infrared fm space transmission equipment
Inventor: INAZAKI KENZO
IPC: H04B10/11
Filed: 1987-09-08
Abstract: PURPOSE:To improve the distortion rate of a demodulated signal by providing a band stop filter having frequency characteristics, which cancel the gain difference in a band of the frequency characteristics which a tuning light reception part has, on the reception side. CONSTITUTION:A band stop filter 26 having the frequency characteristics which cancel the gain difference in the band of the frequency characteristic which a tuning light reception part 22 has is provided on the reception side. That is, when FM infrared rays subjected to space transmission are received on the reception side, the output signal of the tuning light reception part 22 is the FM signal including an AM component because the frequency characteristics of the tuning light reception part 22 has the gain difference in the band. This FM signal is inputted to the band stop filter 26, which has the characteristics which cancels the gain difference in the band, and has the AM component eliminated and is demodulated to a data signal by a demodulating part 23. Thus, the AM component of the reception FM signal is eliminated to improve the distortion rate of the demodulated signal.

Title: Method for decreasing converging time of echo canceller
Inventor: KANEMASA AKIRA
IPC: H04B3/23
Filed: 1982-12-22
Abstract: PURPOSE:To decrease the converging time by multiplying a polarity discriminating circuit output by a code of an echo replica signal and averaging the result, then changing a tap correcting coefficient of an adaptive filter in response to the absolute value in a 2-wire bidirectional transmission echo canceller. CONSTITUTION:Assuming an AMI code as a transmission line code and one tap as an echo, then an echo e(K) is expressed as e(K)=(+e,0,-e), where the probability of generation of +e, -e, and zero is respectively 1/4, 1/4, 1/2. Further, a receiving signal s(k) is expressed as s(k)=(+s,0,-s), where the probability of generation of +s,-s, and zero is respectively 1/4,1/4, 1/2. Moreover, a noise n(k) is neglected. The probability of generation of positive and negative inputs to an averaging circuit DAC16 is listed on Table 1 from the conditions above. When e(k)>s(k) and the echo canceller starts operation, the probability of generation of positive, negative, zero inputs to the DAC 16 corresponds to Table 1-1. Thus, a positive value is obtained from the output of the DAC 16. Thus, a tap correcting value r'(1)(k) corresponding to Table 1 (1) is decided by an ab solute value circuit 17 and multipliers 18,19. When the probability of generation moves to of (2),(3) of Table 1, then respective tap correcting values are obtained.

Abstract: PURPOSE:To realize the retrieval of a lower rank warehouse up to a higher rank warehouse as well as the retrieval of various decomposition patterns of set commodities just with a single input action by storing the physical distribution structure and the decomposition patterns of set commodities into a parameter file. CONSTITUTION:When an order 6 gives the preference to a physical distribution structure, a parameter reference means 3 refers to the physical distribution structure record stored in a parameter file 1. At the same time, a stock retrieving means 4 checks the a stock file 2 with the nearest depot werehouse C1 defined as a key. Then a comparison means 5 compares the stock quantity of the file 2 with the value of the order 6. When noncoincidence is obtained from the comparison, the means 3 refers to the file 1 again and checks the stock of a higher tank terminal warehouse B1 of the physical distribution structure record via the file 2. Then the higher rank warehouses are retrieved continuously until the stock is searched. In the case of the set commodities, the means 3 also refers to the file 1 and the means 4 retrieves the file 2 with its form defined as a key. This retrieving action is continued until the stock is searched or the file 1 ends. Thus the stock mortgage is attained just with a single input action.

Title: Electroplating device
Inventor: OYAMA SADAKIMI
IPC: C25D17/10
Filed: 1989-08-31
Abstract: PURPOSE:To increase the amount of materials to be plated in a plating bath and to uniformize electrodeposition by supporting a material to be plated and an auxiliary anode plate in opposition to a frame and opposing an anode to the side surface of the auxiliary anode plate. CONSTITUTION:The auxiliary anode plate 27 and the material 8 to be plated are alternately inserted in the detaining parts 26 of the frame 21 in the electroplating device 20. The auxiliary anode plate 27 is placed on both sides. The side surfaces of the material 8 and auxiliary anode plate 27 are confronted with the anode 4. A current weaker than that for the anode 4 is applied to the auxiliary anode plate 27 to control the electric field distribution of the anode 4, hence the amt. of the plating film to be deposited on the material 8 is adjusted, and the film thickness is uniformized. Since a decrease in the electric field strength at the center of the material 8 far from the anode 4 is corrected by the current from the auxiliary anode plate 27, the current density on the entire surface of the material 8 is practically uniformized, and the film is formed in uniform thickness.

IPC: G01S7/32
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To detect a target signal accurately even when a dynamic fluctuation appears in the clutter by introducing an adaptive processing into the setting of a threshold being employed at the scan correlation processing. SOLUTION: An adder circuit 24 adds the cell average and the mean deviation of input signals X to set a threshold value. An operating circuit 10 sets a zero specific gravity for the input signal X having a level lower than the threshold value and performs weighted addition of the input signal X and a radar signal on a memory circuit 11. Since the threshold is set adaptively at each point of time depending on on the level and the fluctuation of the input signal X, even such a clutter as exhibiting a random level fluctuation can be suppressed properly.
