Title: Apparatus for reproducing optical disc
Inventor: ARATA TADAO
IPC: G11B7/121
Filed: 1993-03-10
Abstract: PURPOSE:To easily and efficiently clean an objective lens in touch with a cleaning member of a dummy disc by vibrating the objective lens by means of a tracking controlling mechanism in a direction to control tracking. CONSTITUTION:When a dummy disc having a felt or the like cleaning member attached to the surface thereof is loaded and a cleaning instruction is commanded, it is switched to a focus servo signal, thereby impressing a direct current bias signal from a bias power source 25 and shifting an objective lens upward by a constant amount via a driver 31. Then, it is changed to a tracking servo signal, and an alternative current 1-5Hz voltage is supplied from an oscillator 26. The objective lens is consequently vibrated via a driver 32 in a direction to control tracking. In this manner, the surface of the objective lens can be efficiently cleaned under the contact pressure not adversely influencing the supporting structure for the objective lens.

Title: Pll circuit
Inventor: MORI YASUYUKI
IPC: H03L7/08
Filed: 1987-03-27
Abstract: PURPOSE:To eliminate the pulsation of an output frequency in the case of locking and the drift in holding the output frequency by providing a constant current source connected to an input terminal of a low pass filter. CONSTITUTION:A constant current source 6 is connected to the input terminal of an LPF 2. Thus, a constant current source 6 acts like to cancel the output leak current of a phase comparator 1, the leakage current of an integration capacitor of the LPF 2 and the input current of the variable frequency oscillator 3. Since the constant current source 6 is connected to the LPF 6 to cancel the leakage current being a cause to fluctuate the output voltage of the LPF 6 in this way, the pulssation of the output frequency at lock due to the leakage current and the output frequency drift in holding the output frequency are eliminated and the circuit operated stably is obtained.

Title: Pen rising and falling apparatus in recording apparatus
Inventor: SASAKI NAOTAKA
IPC: B43L13/00
Filed: 1990-03-27
Abstract: PURPOSE:To reduce the noise of a recording means, to extend life and to suppress a jumping phenomenon by energizing an actuator for predetermined time and subsequently de-energizing the same for a predetermined time and again energizing the actuator to allow a pen to land on recording paper. CONSTITUTION:When a drawing order is inputted to a recording apparatus, a pen falling process is started and the voltage applied to a direct-acting solenoid 14 is held for a predetermined time and the plunger 13 of the direct-acting solenoid 14 begins to be attracted. Therefore, a pen point follows a falling locus during this time. Thereafter, when the solenoid is turned OFF for a predetermined thinning time, the tensile spring 19 applying rising operation to a pen 4 acts in the direction pushing up the plunger 13 of the direct-acting solenoid 14 but the falling action of the plunger 13 due to inertia suppresses the aforementioned rising action at this time and the falling speed of the plunger 13 is decelerated. Thereafter, the applied voltage of the direct-acting solenoid 14 is again turned ON and the pen 4 gently lands on finally. As a result, a jumping phenomenon is suppressed.

Filed: 1991-04-10
Abstract: PURPOSE:To reduce circuit size and to improve circuit efficiency by providing this digital signal processor with the 1st and 2nd computing elements having respectively specific functions and a memory means. CONSTITUTION:The image of respective sampling points are inputted in the order of d to d, to d, d to d and N data are arranged in the horizontal direction. When the data d to d are inputted, a computing element OP multiplies respective data d to d by a coefficient k3/k0 and accumulatively stores the multiplied data in a register R. When the data d to d of the succeeding line are inputted, the computing element OP changes the coefficient to k3/k0 and an adder AD adds data from the element OP to data preceding N data which are outputted from the register R and inputs the added data to the register R. In the 3rd line, the coefficient of the element OP is changed to k3/k0 and (1/k0)(k3.d +k2.d +k1.d)=D is obtained from the adder AD. Consequently an output [d ] obtained by smoothing, inter-polating and filtering the input data [d ]based upon the coefficients k0 to k3 can be outputted.
