Title: Automatic bias adjusting method of magnetic recording and reproducing device
Inventor: FURUYA HIDEAKI
IPC: G11B5/027
Filed: 1982-04-05
Abstract: PURPOSE:To set and adjust a proper bias quantity in a short time, by comparing recording and reproducing levels of a mddle-band frequency signal and a high- band frequency signal with a bias quantity in the center of the range where the bias quantity is varied in steps and judging this comparison result and repeating this operation. CONSTITUTION:The first test is performed with the bias quantity in the (1+n)/ 2th step, and (1+16)/2=8.5 is true because of n=16, and data in the 9th step is used as the bias quantity to record and reproduce reference signals having 1kHz and 10kHz, and it is judged whether reproduced output levels are equal to each other or not. If they are equal to each other, data 9 at this test time is defined as a proper value. If they are not equal to each other, it is judged whether the reproduced output level of the reference signal having 10kHz is higher or not, and data in the 9th step is used as a step quantity to perform the second test. Thus, since the proper value of the bias quantity is discriminated by a maximum of three tests in case of 16 steps, the number of tests is reduced considerably to shorten the adjustment time considerably.

Title: Semiconductor memory device
Inventor: KOSHIZUKA ATSUO
IPC: G11C11/413
Filed: 1989-03-10
Abstract: PURPOSE:To speed up writing operation by controlling a data input circuit and a write circuit directly by a write control circuit. CONSTITUTION:When an external write enable signal, the inverse of WEIN is held at L level, an internal write enable signal WC which is outputted by the write control circuit 5 rises to H level a specific delay time later. Consequently, the write circuit 3i becomes active. Namely, a couple of data D and the inverse of D which are inputted from a data input circuit 6 are amplified and outputted to corresponding data buses DB and the inverse of DB. When the signal, the inverse of WEIN is held at H level, the internal write signal outputted from the circuit 5 falls to the L level a specific time later. Then the circuit 3i becomes inactive. Thus AC characteristics are improved and writing operation is therefore speeded up.
