Title: Optical amplifier
Inventor: MASAKI KATSUMI
IPC: H04B10/079
Filed: 1991-09-18
Abstract: PURPOSE:To obtain a stable output by amplifying optical signal with a stable gain without being affected by ambient temperature and wavelength of input optical signal. CONSTITUTION:Output light of a rare earth doped optical fiber 1 is extracted by an optical divider 5, a filter 8, and a photodiode 7 and converted into electric signals. An obtained electric signal is converted into a dc signal by a preamplifier 9 and an integrator 10, and the level of this dc signal is compared with a preset reference level which a reference power source 12 generates by a comparator 11. A drive circuit 13 receives a result of comparison from the comparator 1 and adjusts the luminous amount of a laser diode 3, that is, the magnitude of excitation laser light.

Patent JP-S6299221-A (JP)
Title: Constant speed running device for automobile
Inventor: MATSUMOTO MAKOTO
IPC: B60K31/06
Filed: 1985-10-25
Abstract: PURPOSE:To prevent a vehicle from hunting, by providing such an arrangement that the vehicle is shifted up after a first set time elapses when the vehicle speed exceeds a set vehicle speed by a predetermined value during the vehicle running on a slope, and the vehicle is shifted up after a second set time elapses when the vehicle speed comes to be below a predetermined value. CONSTITUTION:When an actual vehicle speed VA exceeds a set vehicle speed VS which is set by turning on a set switch 16, by a predetermined value DELTAV, a control device 11 delivers a signal to an automatic speed change gear 21 after a time DELTAt1 elapsed so that a vehicle is shifted down to the third speed stage. Further, when the vehicle speed VA is less than VS+DELTAV due to the shift- down, the vehicle is shifted up from the third speed stage to the fourth speed stage. In this case, the control device 11 computes a vehicles speed variation rate dVA/dt just before the shift-down or the shift-up, and therefore, the first set time DELTAt1 is shortened in accordance with the thus computed variation rate while the second set time DELTAt2 is set to be long. With this arrangement, it is possible to prevent the vehicle from hunting during the shift-up or the shift- down.

Patent JP-S6293686-A (JP)
Title: Analog electronic clock
Inventor: KUROODO ERIKU REENBERUGAA
IPC: G04C3/14
Filed: 1986-10-09
Abstract: An analog electronic watch comprising electronic circuitry is described, a first motor for driving hours and minutes hands, a second motor for driving a seconds hand, and a photoelectric sensor connected to the circuitry is described. The sensor reacts to strong ambient light by producing a first signal. In response to this signal the circuitry issues control signals to the two motors to activate them. If the light fades, the sensor produces a second signal and the circuitry then only issues control signals to the first motor. Stopping the second motor, when the light becomes too dim to read the time, saves energy. A memory circuit enables the seconds hand to be synchronized with the minutes hand whenever the ambient light becomes sufficiently strong to warrant activation of the second motor.

Title: Exciting device for position detector
Inventor: UCHIYAMA ATSUSHI
IPC: G01B7/00
Filed: 1985-10-28
Abstract: PURPOSE:To obtain a trapezoidal wave substantially equivalent to a sine wave by a simple construction, by providing a counter counting output pulses of an oscillator and an integrator taking a rectangular wave out of the output of this counter and converting this rectangular wave into the trapezoidal wave. CONSTITUTION:When an oscillator 1 is made to oscillate at 5MHz, for instance, an output of the highest bit b9 of a 10-bit counter is a symmetric rectangular wave of 5MHz, while the output of a lower bit b8 is a symmetric rectangular wave of 5MHz. When these two rectangular waves are inputted to an exclusive OR circuit 13, the output thereof is a symmetric rectangular wave of 5kHz whose phase is shifted from that of the output of the bit b9. When the output signal of the bit b9 and the output signal of the circuit 13 are amplified 5, 6 and then integrated by integrators 11, 12 respectively, trapezoidal waves are obtained. Viewed as exciting signals to be given to a resolver, these trapezoidal waves operate almost equivalently to cosomegat and sinomegat shifted in phase by 90 deg. from each other. Since these trapezoidal waves are free substantially from a phase error, detection of a position can be performed with high precision when they are used as primary excitation waveforms for a position detector such as the resolver.
