Title: 3-terminal type thick film resistor and trimming method therefor
Inventor: ISHIZEKI NOBUYUKI
IPC: H01C13/02
Filed: 1988-11-30
Abstract: PURPOSE:To reduce the area of a resistor occupying on a hybrid circuit board and the size of the board, and to enhance its density by providing a central electrode terminal at the central region of a thick film resistor formed between a pair of electrode terminals to compose a voltage divider of one resistor. CONSTITUTION:Conductor pastes are printed at an interval in parallel with each other on a hybrid integrated circuit board to form a pair of electrode terminals 1, 2. In this case, a central electrode 3 is simultaneously formed of conductor paste at the intermediate between the terminals 1 and 2. Then, the paste is so printed in a rectangular shape as to bridge the terminals 1, 2 and 3, and seized to form a thick film resistor 4. A groove 5 is a trimming groove for regulating the resistance values of a resistor region between the terminals 1 and 3 and the whole resistor. In an equivalent circuit, the ratio of R1 to R2 can be altered by one trimming groove. That is, when the groove 5 is increased, the increase in the resistance value of the R1 is larger than that in the R2, and its voltage dividing ratio is varied.

Title: Waveform equalizing circuit
Inventor: KIMURA SHUNPEI
IPC: G11B20/10
Filed: 1990-11-07
Abstract: PURPOSE:To achieve low cost, compact configuration and the improvement of waveform equalizing performance by differentiating the read-out regenerated signal, and subtracting the differentiated regenerated signal from the regenerated signal before the initial differentiation. CONSTITUTION:A first differentiating circuit 17 differentiates the read-out regenerated signal. A low-pass filter 18 removes high frequency noises. A second differentiating circuit 19 further differentiates the regenerated signal which is differentiated with the first differentiating means 17. A low-pass filter 20 is provided. A subtracting circuit means 21 subtracts the regenerated signal corresponding to the output of the second differentiating means 19 from the regenerated signal before the differentiation with the first differentiating means. In this way, the regenerated signal which is read out of a data recording medium undergoes differentiation twice. The gain of a certain value is imparted to the signal which is differentiated twice. The obtained signal is subtracted from the original regenerated signal. Thus, the regenerates waveform is made to be the smaller waveform. Even for the waveform causing the interference between codes, the interference degree can be decreased to a certain level. In this way, low cost, compact configuration and the improvement of waveform equalizing performance can be improved.
