Title: Driving device for light emitting element
Inventor: OKADA KIMIYOSHI
IPC: H04B10/07
Filed: 1980-12-18
Abstract: PURPOSE:To prevent output pulses of an abnormal light of a light emitting element from being transmitted at an input signal break time, by detecting a pilot signal superposed onto the input signal. CONSTITUTION:When a pulse frequency modulated PFM signal is given to a terminal 1, the pulse width of this signal is contracted to a pulse width required for setting and resetting an FF2 by an R-S pulse generating circuit 3, and the signal is inputted to the FF2, and an output Q of the FF2 is inputted to a tuning amplifier 11 which detects the amplifies only a pilot PL signal included in the PFM signal. The output of the amplifier 11 is inputted to a comparator 13 through a peak detector 12, and the comparator 13 discriminates PL signal components to set their output to the L level. As the result, an NAND gate 5 is opened, and the Q' output of the FF2 is inputted to a circuit 7 for driving a light emitting element, and an optical output signal similar to the PFM input signal is obtained from a light emitting element 8. When the input signal is broken, the output of the detector 12 becomes zero, and the output of the comparator 13 is H-level, and the output of the gate is L-level. Consequently, even if a noise is generated from an electric circuit, the element 8 is not driven.

Title: Electromagnetic induction charger
Inventor: SARUWATARI TOMOSUMI
IPC: H02J7/00
Filed: 1989-07-10
Abstract: PURPOSE:To prevent mismatch of time, during charging operation, by setting the frequency of AC magnetic field to be applied externally onto an electronic wrist watch to such value as not influencing onto the step motor in the watch. CONSTITUTION:A DC voltage generating means 8 in a charger 7 generates DC voltages VDD1, VDD2. The DC voltage VDD1 provides power supply for a frequency generating means 9. The frequency generating means 9 generates a signal having frequency fD and the DC voltage VDD2 is applied onto the terminal of a primary coil 2 while being synchronized with the frequency fD thus producing AC magnetic field having frequency fD through the primary coil 2. A step motor contained in an electronic wrist watch functions erroneously if the frequency of external AC magnetic field is lower than 500Hz but is not influenced by the external AC magnetic field having frequency higher than 600Hz. Consequently, a charger causing no mismatch of time can be obtained when the frequency is set to such value as causing no influence onto the step motor.

Title: Troidal-shaped continuously variable transmission
Inventor: YASUMA YUKIO
IPC: F16H15/38
Filed: 1986-07-30
Abstract: PURPOSE:To reduce the dimension of the device by making the cylinder diameter of a cylinder mechanism for operating a power roller supporting mechanism smaller on the driven side in comparison with on the driving side. CONSTITUTION:The diameter phi1 of the cylinder 40 of a cylinder mechanism arranged on the drive side of a trunnion 35 which supports a power roller 33 is made larger than the diameter phi2 of a cylinder 41 on the driven side. Therefore, the cylinder mechanism on the drive side can receive a revolution torque by a relatively small hydraulic pressure. While, since the revolution torque on the driven side is smaller than the revolution torque on the drive side, the revolution torque can be certainly received, even if the cylinder diameter phi2 of the cylinder mechanism on the driven side is reduced. Therefore, the width of the inside case 27 of a casing 26 can be reduced, and dimension and weight can be reduced by reducing the between-axis distance of an operation transmission system.
