IPC: F16K31/06
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To always conduct duty ratio calculation at suitable characteristics even of a change in temperature conditions or power source voltage occurs, by determining a proportional coefficient in a calculation expression for deter mining a reference duty ratio by reverse operation and updating it. SOLUTION: The duty ratio D of driving pulse current is calculated based on proportional integral control from a deviation ΔI of target current Iobj to an electromagnetic pressure proportional control valve commanded by a controller from output current I is calculated based on an expression I (Kp :proportional gain, KI:integral gain). A reference duty ratio Do to the target current Iobj is calculated as an expression II, where a proportional coefficient (a) and a constant (b) in expression II are values under a certain temperature condition. To meet characteristic change due to temperature change in the energizing section of the electromagnetic pressure proportional control valve, the reverse operation of an average proportional constant (a) during preset time is conducted to be replaced with (a) in the expression II sequentially.

Inventor: KUMAZAWA YUKIO
IPC: G06F12/12
Filed: 1989-09-07
Abstract: PURPOSE:To improve the hit ratio of a cache memory and to shorten the processing time by fetching data which are being transferred between another cache memory and a main memory through a system bus but is not included in the cache memory concerned providing for the future.

Title: Correcting circuit of pincushion distortion
Inventor: KAMAKURA MASAKAZU
IPC: H04N3/23
Filed: 1982-12-27
Abstract: PURPOSE:To correct pincushion distortion almost completely by superposing a nearly S-shaped current which is modulated by a signal that becomes large in the center of vertical synchronism upon a horizontal deflecting current. CONSTITUTION:The secondary winding 9b of a transformer 9 for voltage-current conversion is connected between a horizontal deflecting coil 4 and a capacitor 5 for S-curve correction. A correcting voltage VP is applied from a modulator 10 to the primary winding 9a of the tansformer 9. This voltage VP is shown by a triangular-wave broken line (a) which has a peak, for example, in the center of a horizontal period TH. Further, a correcting current IS which is shown by a nearly S-shaped solid line (b) flows through the coil 4 in addition to the horizontal deflecting current IY, so deflection is suppressed on the left-hand side on a screen and accelerated on the right-hand side. Then, the current IS is small on both ends in the vertical direction of the screen and maximized in the center. Thus, pincushion distortion is compensated almost completely.

Title: Deemphasis switching circuit
Inventor: SUZUKI HIROSHI
IPC: G11B20/10
Filed: 1986-09-29
Abstract: PURPOSE:To eliminate a need of switching of the frequency characteristic of an output amplifying means by fixing the output amplifying means to the deemphasis processing function and switching the frequency characteristic of an input means to the preemphasis characteristic by the digital signal processing if an input signal is not subjected to preemphasis processing. CONSTITUTION:The output of a D/A converter 11 passes a low pass filter 12 which eliminates an unnecessary high frequency component and is supplied to an output amplifier 13. The output amplifier 13 is fixed to the deemphasis characteristic to have a certain characteristic independently of the property of the input signal of an input terminal 10, and switching of this characteristic is unnecessary because the signal which is not subjected to reemphasis processing is subjected to preemphasis by a digital filter 16 and is supplied to the output amplifier. Consequently, a system has a flat reproducing frequency characteristics. Thus, it is unnecessary to switch the frequency characteristic in the analog stage.
