IPC: H04B3/06
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To make a device compact and light in weight by surely and exactly finding out an optimum estimate area through a simple algorithm when judging the area, where the most optimum signal estimation is enabled, from the impulse response of transmission line for facilitating power consumption reduction and circuit configuration. SOLUTION: A transmission line characteristic detector 102 detects transmission line characteristics from a received input signal at the time of training signal reception through an input terminal T1.

An accumulator 104 accumulates the absolute values of amplitude components from the absolute value computing element 103, and a maximum value detector 105 detects which timing in this output signal shows the maximum value.  While using the transmission line characteristics from the transmission line characteristic detector 102 and the timing signal outputted from the maximum value detector 105, a delay discrimination feedback type sequential estimator 106 outputs maximum likelihood estimate data, to which the maximum likelihood estimation of received input signal is performed, through an output terminal T2.

Title: Image processing system
Inventor: OTA YUTAKA
IPC: B41J2/205
Filed: 1987-06-25
Abstract: PURPOSE: To obtain the printer output of good picture quality with good gradation reproducibility even from a photograph of scenery or a person by varying how large additional data is large according to how an edge detection signal is large, and determining the number of output picture elements according to the comparison processing result of the level of an additional data sum signal.  
     CONSTITUTION: When an original part has small variation of an original read signal between nearby picture elements, an edge detection part 6 outputs an etching detection signal 16 with a small value. An additional data quantity control part 8 multiplies the additional data 17 by a larger integer as the edge detection signal 16 is smaller and outputs control additional data 18. Then an additional data adding part 9 outputs the sum value of an original read signal 12 and control addition data 18 as an additional data sum signal 19. Then an output picture element determination part 10 determines picture elements whose number is indicated by an output picture element quantity signal 14 in the order of the large picture element of the additional data sum signal 19 by outputting dots ink. Consequently, the printer output of good picture quality with good gradation reproducibility is obtained even from a photography of scenery or a person.

Abstract: PURPOSE:To prevent a cassette from being misloaded by fixing a pressure plate to a tray main body, making it abut on a stop plate pivoted rotatably on a fixed member above a tray, and controlling the rotating operation of the stop plate. CONSTITUTION:When the cassette 8 is loaded, the pressure plate 5 fixed to the tray abuts on the stop plate 6 supported pivotally on the fixed member above the tray and the stop plate 6 controls the forward movement of the cassette 8 inserted into the cassette holder 2, thereby preventing the cassette 8 from moving forth. Further, when the tray 1 is drawn in to move horizontally, the pressure plate 5 also moves out of the rotational range of the stop plate 6, which becomes rotatable; and the cassette holder 2 is lowered wit an external driving force to lower the cassette 8 to a specific position of a deck, thereby completing the loading of the cassette 8.
