Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To improve reproducing operation performance by allowing the low frequency components of a tracking error signal to control a variable gain amplifier circuit, while a tracking servo loop is off, and thereby quickly precisely drawing a servo. SOLUTION: During the period that a switch 22 is connected to a TA terminal, a tracking error signal STE from a tracking error amplifier circuit 1 controls a variable gain amplifier circuit 3B through a buffer amplifier 24, with low frequency components extracted by LPF 23.

A band metal (band steel) is plated at the contact angle of 230 deg.. In the B in each example in the table, the energizing of the groove positioned on the outlet side of the contact region of the band metal with the roll is stopped when the passing velocity is decreased from 200m/min of the A to 100m/min, and the plating time (energizing time) of the band metal contact region is equalized with the A. In addition, the color tone is visually judged. By this method, the deterioration of the plating color tone due to the passing velocity is prevented, and the commodity value can be increased. In the examples and reference examples in the table, plating is carried out on the condition A, the condition is then switched to the condition B, and plating is carried out.

Filed: 1990-11-05
Abstract: PURPOSE:To easily execute the fine adjustment for taking orthogonality in a short time, and also, to improve the uniformity of a high frequency magnetic field distribution in a probe by forming integrally a wind and a guard ring of two pairs of probe coils, moving them in the peripheral direction of a probe bobbin, and rotating the center shafts of the pair of probe coils. CONSTITUTION:While confirming the isolation of an electric characteristic of each pair of probe coils, the vertical 1 and wings 21, 25 being an integral structure are moved in parallel in the peripheral direction of a probe bobbin. According to this method, the orthogonality can be adjusted in a state that the inductance constituted of the vertical and the wing of each pair of probe coils, and the capacitance constituted between the wing and the guard ring are constant. Therefore, each pair of probe coils is resonated by almost the same inductance and capacitance, and constitutes a QD probe whose symmetric property is satisfactory electrically. Accordingly, a generated high frequency magnetic field distribution has a satisfactory symmetric property and becomes uniform. Also, a guide groove is provided so that the wings 21, 25 and the vertical 1 can move in parallel in the peripheral direction of the probe bobbin.

Title: Steering angle detecting device for vehicle
Inventor: MATSUO YOSHIAKI
IPC: B62D101/00
Filed: 1988-11-25
Abstract: PURPOSE:To make it possible to precisely compensate the neutral position of a steering angle by detecting a running condition of a vehicle by use of a status value detector including either a yaw rate sensor or a G sensor, and by determining such that the vehicle runs straightforward when its detection output signal is below a predetermined value. CONSTITUTION:An ECU receives output signals from a G sensor 10, a yaw rate sensor 14 and a steering sensor 18, and discriminates, at first, the large and small relationship between a vehicle speed V and a predetermined value (a). If V>a, the ECU determines the large and small relationship between the absolute value ¦YR¦ of an output YR from the yaw rate sensor 12 and a predetermined value (b) set by the vehicle speed V, and if ¦YR¦<b, it allows a timer to count, and thus counted value is compared with a predetermined value N. If RC>N, it is determined that the vehicle runs straight-forward so as to determine the steering position as a neutral position. Thereby the neutral position of the steering sensor 18 is compensated in accordance with the result of the determination.
