Title: Frequency standard
Inventor: AKIYAMA KOJI
IPC: H01S5/00
Filed: 1987-07-20
Abstract: PURPOSE:To make frequency accuracy excellent and to enable size reduction by stabilizing the wavelength of a semiconductor laser according to the absorption of one light beam, and generating a standard frequency according to the absorption of the other light beam. CONSTITUTION:The output light of the semiconductor laser 30 is split by a beam splitter (BS) 32 in two directions, reflected light is incident on an acoutooptic modulator (AOM) 34 through a mirror 33 and frequency-modulated, and the modulated light is detected by a photodiode (PD) 38 after passing through an absorption cell 35. When the output of a lock-in amplifier (LIA) 391 is 0, the output waveform of the laser 30 is locked to an absorbed ray of Rb<87>. The output light after having passed through the BS 32 is incident on the absorption cell 35 at a different position, and its transmitted light is detected by a PD 43, whose output locks the output frequency of a voltage- controlled crystal oscillator (VCO) 46 at a frequency corresponding to a transition frequency determined by the extremely fine level of Rb<87>. Consequently, the frequency accuracy is superior and the size reduction is possible.

Abstract: PURPOSE:To execute balance adjustment and offset adjustment at a high speed without requiring a particular disk by using a servo error signal when a laser is turned instantaneously. CONSTITUTION:The laser 1 is turned off instantaneously by a controller 11 in the state of that a beam traverses a track at a focus-on time, and the output of a differential amplifier 7 at the time is outputted to an adder 8 as an offset adjustment amt.

Patent JP-H0232714-A (JP)
Title: Ground directional relay
Inventor: MURAKAMI YUICHIRO
IPC: H02H3/38
Filed: 1988-07-20
Abstract: PURPOSE:To prevent erroneous function upon recovery from fault and to improve the reliability by holding data obtained before occurrence of fault until all stored values are updated. CONSTITUTION:When a fault is detected in step S9, a value '7' is set as an initial value into a counter C in step S20 and the process proceeds to step S11. Since the value '7' is employed as the initial value, 6 periods lay between a new value e4n and an old value e4m. If no fault is detected in step S6, the count of the counter C is decremented by '1' in step S21 then the process proceeds to step S22 where judgement is made whether the content of the counter C is positive. If the content of the counter C is positive, the process proceeds to step S11 while when the count is zero the process proceeds to step S23 where the count is set to 1, then the process proceeds to step S10. By such arrangement, internal and external faults are detected based on zero-phase current and zero-phase voltage.
