IPC: G11B7/09
Filed: 1982-07-22
Abstract: PURPOSE:To obtain an optical information detector which is easily controlled with simple constitution, by eliminating a reflecting mirror and setting a 2- split photodetecting element for tracking detection in place of the reflecting mirror. CONSTITUTION:A dividing line 9-3 between photodetecting surfaces 9-1 and 9-2 of a photodetecting element 9 for tracking detection is set in parallel to a track 11 and so as to pass through an optical axis.

While the dividing line between the photodetecting surfaces of a focus detecting photodetecting element 10 also passes through the optical axis and is set rectangularly to the track 11. Thus this dividing line is parallel to the edge 9-4 and the dividing line 10-3 of the element 10 and put on the surface of the optical axis together with the line 10-3. Therefore, the edge 9-4 has a knife edge effect to the focus detection, and at the same time the element 9 is set in a far field placed away from the condensing point of a condenser lens 7. Thus the tracking can be detected.

Title: Automatic gain control circuit
Inventor: FUJITA YASUHIRO
IPC: H03G3/20
Filed: 1978-10-16
Abstract: PURPOSE:To secure the automatic gain control even for the input of the ultra-low frequency by having the peak detection for the input signal and then giving the control for a fixed time to the variable gain amplifier via the peak value. CONSTITUTION:Timing pulse C showing the positive peak point is produced from input signal A via peak detector 2 to be used for the gate signal of A/D converter 3. At the same time, gate signal B is produced via zerocross detector 4, and analog signal D proportional to the output of converter 3 is transmitted through D/A converter 5. The output of converter 5 has been held for a cycle starting zero point which was sampled by output C of detector 2 through converter 5. In other words, the peak value of the input signal is supplied to variable gain amplifier 1 for the period of a cycle in the form of gain control signal D.

Patent JP-H02304481-A (JP)
Title: Display controller
Inventor: YAMAUCHI TAKESHI
IPC: G09G5/00
Filed: 1989-05-18
Abstract: PURPOSE:To reduce power consumption by cutting off the transfer of a clock signal to the first control circuit with a gate circuit when a signal from a central processor instructs that the first control circuit is under an inactive state. CONSTITUTION:When access from a CPU 3 is stopped, the control circuit 5 becomes the inactive state that it does not particularly execute any action. Since the output of an OR gate 10 becomes at an 'L' level and the reset of a programable counter 11 is released, the clock signal from a clock input terminal 16 is started to be counted by the programable counter 11 and a carry output RCO becomes at an 'H' level. Besides, since the reset of an R-S flip-flop 12 is released and the signal of the 'H' level is given to a set terminal S from the carry output RCO of the programable counter 11, the R-S flip-flop 12 is set and a 'not output Q' becomes at the 'L' level. Due to that, an AND gate 13 cuts off the clock signal transmitted to a control circuit system timing generation circuit 8 from the clock input terminal 16. Thus, the control circuit 5 is stopped and the power consumption in the control circuit 5 is reduced.

IPC: H02M3/155
Filed: 1990-05-17
Abstract: PURPOSE:To decrease the weight of high-frequency noises to an input terminal by magnetically joining one end of an added winding to the input side of a choke coil so as to have the same polarity as the choke coil, earthing the other end thereof, and connecting a current regulation inductance to the added winding in series. CONSTITUTION:One end of an added winding 13 is earthed and the other end thereof is connected to the input side of a choke coil 6 through a series circuit consisting of a current regulation inductance 14 and a direct current removing capacitor 15. When a switching element 7 is turned on, a current i1 passed through the choke coil 6 increases linearly. At the same time, a current i2 passed through the added winding 13 decreases linearly. When the switching element 7 is turned off, the current i1 decreases linearly. At the same time, the current i2 increases linearly. The constant of the current regulation inductance 14 is set so that the amount of the change of the current i1 may be as large as that of the current i2. Thereby a ripple current passed through an input smoothing capacitor 4 can be off set and the weight of high-frequency noises to an input terminal can be decreased.

Title: Method and device for control of air spring type vibration eliminating pedestal
Inventor: KAMATA TORU
IPC: G05D19/02
Filed: 1990-05-19
Abstract: PURPOSE:To discontinue the active vibration suppression control when the displaced variable of a loading stage is reduced less than an allowable level by detecting the displaced variable when the loading board supported by an air spring is vibrating and comparing the detected displaced variable with the allowable level. CONSTITUTION:A driving means applies the driving power to a loading stage in order to suppress the vibrations of this board. A displaced variable detecting means detects the displaced variable of the loading board which is supported by a vibration eliminating pedestal via an air spring when the loading board is vibrated. Then a comparison means compares the detected displaced variable with an allowable level. When the displaced variable is larger than the allowable level, a displacement velocity computing means calculates the displacement velocity based on the displaced variable. Then a driving output value computing means calculates the driving output value of an actuation means based on the displaced variable and the displacement velocity in order to suppress the vibrations of the loading board. Consequently, the active vibration suppression control is carried out only when the displaced variable of the loading board caused by its vibration is larger than the allowable level and then discontinued vice versa.

Title: Switching circuit
Inventor: TAKAHASHI KYOICHI
IPC: H03K17/04
Filed: 1987-05-27
Abstract: PURPOSE:To reduce the power consumption and to speed up the driving speed of a switching element, by driving the switching element by adding an output current which is temporarily obtained in corresponding to discharge to the steady output current of a current mirror circuit provided with a speed-up capacitor whose discharge is controlled. CONSTITUTION:A speed-up capacitor C1 which obtains a charge and discharge currents in corresponding to the turning-on and turning off operations of a transistor Q1 acting as a switching means is added to a current mirror circuit 2. When the output circuit 5 on a power source side of output circuits 5 and 6 is driven in corresponding to input signals Vin, an output current which temporarily increases in corresponding to the discharge current of the capacitor C1 is obtained and supplied to the power source side output circuit 5. Since a large current is temporarily supplied at the time when the output circuit 5 is switched to a turned-on state, therefore, an output current Vout can be made to rise at a high speed and, moreover, this switching element is driven with a low current in a steady state. Accordingly, the power consumption of this switching element can be reduced and a high-speed switching operation can be attained with this switching element.
