Title: Classification of semiconductor memory device
Inventor: SAI TOSAN
IPC: G06F12/00
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To improve performance of system by setting the optimum signal timing for module formed of respective devices. SOLUTION: A CBR sensing means 90 senses that the CAS signal has transited precedingly to the 'L' level more quickly than the RAS signal among the input signal in the DIF device. Thereby, an output of the sensing means 90 controls the data output to cause the DIF device not to output any data. When CBR counter test timing required for refresh is input from DRAM, the DIF device senses such input and holds the output of DIF device in the high impedance condition. Thereby, when the DRAM module and DIF module exist simultaneously in the same system, after the CBR counter test timing is applied to the data output control means 80, an output of the device is sensed to easily classify the device loaded to the module.

Inventor: KOUNO KOUUN
IPC: H04N9/78
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the crosstalk component and also to reduce the cost of a comb-line filter by inputting the selection output to the 2nd addition, input of an addition circuit as a delay signal. SOLUTION: A 1H delay device 22 of a low band comb-line filter 20 delays the reproduced low band chrominance signal input by almost 1H. A phase shifter circuit 23 outputs an input low band chrominance signal after shifting it by a time equivalent to 90 degrees. Thus a delayed reproduced low band chrominance signal that is delayed by 1H and also shifted by 90 degrees against the reproduced low band chrominance signal input obtained before 1H, i.e., a signal having a phase opposite to the present reproduced low band chrominance signal input is outputted as the output of the circuit 23. At the same time, an amplifier circuit 24 amplifies the inputted delayed reproduced low band chrominance signal and outputs the in-phase and anti-phase signals of the delayed reproduced low band chrominance signal respectively.  Then a switch circuit 25 undergoes the changeover control by a switch signal of 30Hz to alternately select and output the inputted in-phase and anti-phase signals of the delayed reproduced low band chrominance signal.

IPC: H04L29/08
Filed: 1989-12-29
Abstract: PURPOSE:To sharply decrease the generation probability of the succeeding communication error or after by automatically setting up a communication speed(CS) so that the succeeding CS is dropped from the current CS only by one level when a communication error is generated in a call based upon an abbreviated number.
