Title: Optical reproducing device
Inventor: INOUE MASAYUKI
IPC: G11B7/135
Filed: 1993-09-01
Abstract: PURPOSE:To stably perform repeated reproduction without being affected by dust by making a light spot shape for reading a phase pit an ellipse shape longer in a track direction and extending a range of reproducing laser beam power. CONSTITUTION:In the first reproduction of an optical disk whose whole surface is an amorphous state, when power P is increased, a part in a light spot 312 of the ellipse shape is crystallized, and a regenerative signal becomes nearly maximum at P4. A part of the pit 310 is crystallized also at P5 or above, and a regenerative signal level is lowered. The phase in the vicinity of a track center of a crystallized phase transition film is not returned to the amorphous state at power P6 or above, the width (d) is increased according to the increase of the P, and is lowered rapidly at p6 or above in the second and succeeding reproduction. The range of the reproducing laser power capable of reproducing repeatedly is P4-P6, and becomes nearly three times the range of a conventional case. Thus, the regenerative signal level is hardly affected by the fluctuation of the reproducing laser power due to dust, and the stable repeated reproduction is performed. The shape of the light spot 312 is made the ellipse shape longer in the track direction, and the light intensity in the periphery of an objective lens is made 20% or smaller of the intensity in the vicinity of the center of the objective lens.

Title: Light emitting element driving circuit
Inventor: UENO SUEO
IPC: H01S5/06
Filed: 1987-08-31
Abstract: PURPOSE:To stably emit a light pulse with prescribed strength, by impressing a driving voltage set at a voltage setting part on a light emitting element by applying intermittent control.

Filed: 1983-11-18
Abstract: PURPOSE:To decrease noise by utilizing the correlation of a picture signal in terms of plane to compensate the less number of quantized levels thereby decreasing quantized error in a differential PCM coding system. CONSTITUTION:A post-processing circuit 12 is added to the reception side and when a difference signal transmitted from a transmission line 9 is small, a discrimination circuit 14 at the reception side zeros the multiplier K of a multiplier K circuit 18 and a multiplier (K-1) circuit 9 and outputs the sum of the difference signal transmitted to the forecast value from a forecast device 11.

Abstract: PURPOSE:To provide an automatic accompaniment playing device of an electronic musical instrument through which a beginner can easily enjoy a music playing with an elaborate automatic accompaniment during a continuous playing. CONSTITUTION:If the data read out by an S41 are music end data, the data on the number of pieces of music to be continuously played are read out among the continuous playing data stored in a continuous playing data memory (S75). In an S77, an end of a continuous playing is judged from the fact that the number of pieces of music which has been played reaches that of music to be played that are read out by the S75 or not. When it is the end of a continuous playing, accompaniment pattern data are switched to ending data (S78), and it is returned to a main routine. On the other hand, if it is judged that it is not the end of a continuous playing in the S77, after one music playing is completed, a code progress number, that is used in an automatic accompaniment of a next playing, is read from the continuous playing data memory (S79).

Title: Continuous variable ratio transmission
Inventor: KURISUTOFUA JIYON GURINUTSUDO
IPC: F16H15/38
Filed: 1988-09-02
Abstract: PURPOSE: To obtain a continuously ratio-varying speed transmission with a simple structure by arranging the first and second input shafts of the epicyclic gear sets and the first and second output shafts of the first and second variators in the way that they are all coaxial. CONSTITUTION: On the low speed side, a clutch 13 is disconnected, while a brake 6 is connected so that the input from an input member 31 drives the first input members 9, 10 of epicyclic gear sets 7, 8 via variators 3, 4. As the brake 6 is connected, an epicyclic gear set 5 drives the second input members 11, 12 of epicyclic gear sets 7, 8 and outputs, through output members 1, 2, the speed variation in accordance with the variators 3, 4. On the high speed side, the brake 6 is disconnected while the clutch 13 is connected so that the variator 3 directly drives the output member 2. The speed of the output member 1 depends on the speed of the two variators 3, 4. The respective input, output shafts of the variators 3, 4 are all arranged coaxially on the same axis 16. Thus it is possible to obtain an efficient continuously ratio-varying speed transmission with a simple structure.

Title: Propagation distortion equializer
Inventor: YAGI TAKESHI
IPC: H04L27/34
Filed: 1984-10-18
Abstract: PURPOSE:To prevent the astable operation of an equalizing circuit by detecting a frame step-out when distortion after equalization is large and fixing the control voltage from a control circuit. CONSTITUTION:A frame step-out detecting circuit and a reset signal generating circuit 20 when detecting a frame step-out generate a reset signal to operate changeover switches 21 and 22 provided in the control circuit. Consequently, the control circuit sends out constant reference voltages Vref1 and Vref2 to the equalizing circuit which uses a recursive filter instead of error signals epsilon1 and epsilon2. Consequently, the fixed reference voltages Vref1 and Vref2 are applied to double balance mixers 5 and 7 in the equalizing circuit, so the equalizing circuit is fixed to flat transfer characteristics. Therefore, even if multipath phasing, etc., having large equalization residuals are inputted, a control signal is stable and the equalizing circuit never operates unstably.
