Title: Synchronous semiconductor memory device and method of testing the same
Inventor: OISHI TSUKASA
IPC: H04L1/22
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous semiconductor memory device that reduces the number of observation pins during the test and outputs the output data at a lowered data rate. SOLUTION: A matching detection circuit 250 to detect the match of data outputted to a plurality of data terminals is provided to an input/output circuit. During the test, the same result is written to the latches 146, 148 and these are read alternately depending on the clock signal. Therefore, during the normal operation, the test result may be outputted with the lower data rate from the terminal to output the data with the double data rate. Thereby observation can be realized even with a low performance tester and the cost of the test can be reduced.

Title: Magnetic recording and reproducing device
Inventor: SHIBATA AKIRA
IPC: H04N5/91
Filed: 1983-01-28
Abstract: PURPOSE:To suppress mutual interference between a sound signal and a video signal by smoothing record equalizing characteristics for a luminance signal, inserting a comb line filter to a liminance signal circuit and connecting a recording chroma signal circuit to a chroma signal equalizing circuit. CONSTITUTION:Parts 20, 21 are a luminance signal (YFM) extracting LPF and a chroma subcarrier suppressing comb line filter respectively and a circuit 22 uniforms synchronous peak potential and smoothes the characteristics of circuits 24, 25. A luminance signal YFM is obtained from the output of a frequency modulation circuit 27. On the other hand, parts 30, 31 are a chroma signal (CL) extracting BPF and a YFM suppressing filter respectively. A part 39 is a CL recording equalizer and a part 41 is a sound signal compressing circuit. Since said constitution prevents the emphasis of the lower band wave of the YFM, the lower band wave is not leaked into a band of an AFM. In addition, connection of a compressor 41 to a sound circuit prevents a sound signal from being distorted by the YFM. Since the CL recording equalizer 39 suppresses the upper wave of the CL, the distortion of the sound signal by the CL is resolved. Smoothing recording current for the YFM suppresses noises due to the DP (differential phase) of a head system and a circuit 35 in the CL circuit prevent leakage from the sound circuit.

Title: Gain variable type differential amplifier
Inventor: ONO JUNZO
IPC: H03G3/10
Filed: 1989-01-20
Abstract: PURPOSE:To sufficiently and accurately obtain desired maximum, medium, and minimum gain by providing the first, second, third, and fourth transistor groups comprising differential pairs, respectively, and performing gain control by combining the turning-on and -off of the third and fourth groups. CONSTITUTION:It is assumed that a direct current I0 flows respectively on transistor TR Q2-Q5 comprising the fist group 1 and the second group 2. Firstly, the gain of an amplifier is varied by a gain control voltage supplied to the third group 3 and the fourth group 4, however, the current I0 flows on the TR Q8 of the group 4 at a state where both the group 3 and the group 4 are turned ON. Therefore, the sum 2I0 of the current I0 and the I0 from the TR Q5 always being turned ON flows to a load resistor R2, then, the medium gain can be obtained. When it is desired to obtain the maximum gain, the group 3 is turned OFF, and the group 4 is turned ON. At this time, since all the currents 3I0 of the group 1 flow on the group 4, a current 4I0 including the current I0 from the group 2 flows on the resistor R2. When it is desired to obtain the minimum gain, the group 3 is turned ON, and the group 4 is turned OFF. At this time, only the current I0 from the group 2 flows to the resistor R2. Namely, all of the medium gain A, the maximum gain 2A, and the minimum gain A/2 can be obtained.
