Title: Gyrator
Inventor: KAWAKAMI IZUMI
IPC: H03H11/42
Filed: 1982-07-09
Abstract: PURPOSE:To obtain a gyrator which can obtain high Q characteristics that are indispensable for formation of a monolithic IC attained with conversion of a filter into an active RC, by connecting a capacitor between the inputs of an operational amplifier constituting an Antonion type gyrator. CONSTITUTION:For an Antonion type gyrator, an input impedance is obtained from an equation I if the gain functions of an OP-AMP are defined as A1(S) and A2(S), respectively. Minute capacities DELTAC1 and DELTAC2 are added to the input terminal of the OP-AMP. Then the input impedance Zin of the equation I is shown by an equation II with addition of only the capacities DELTAC1 and DELTAC2. Therefore, the deterioration of Q and the deflection of L0 owing to the finite gain of the OP-AMP are limited just to C1 and C2, respectively. Then it is sufficient to decide both C1 and C2 so as to satisfy the time of compensation with C1 and C2.

IPC: G03B5/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To eliminate a beat signal generated by interference and to prevent the S/N ratio of a signal outputted from an angular velocity sensor from being lowered by specifying relation among the driving frequency of a driving element, the exciting frequency of the angular velocity sensor and the cut-off frequency of a filter. SOLUTION: By the angular velocity sensor part 101, deflection is detected and outputted to a band-pass filter(BPS) part 102 as an angular velocity signal. Then, this signal is filtered by the BPS part 102. By the driving element 107 of a correction optical part 111, a correction optical element 108 is driven so as to negate the deflection based on the detected angular velocity. Besides, the frequency (fg) of a signal for exciting the sensor part 101, the fundamental frequency (fp) of mechanical vibration occurring by the driving of the element 107 and the cutoff frequency (fc) of the high band side of the BPS part 102 are set so as to satisfy the relation of fc<|m.fg-n.fp|. Provided that (m) and (n) are optional integers being >=1 and they show the degree of the higher harmonic of the respective frequencies (fg) and (fp) when they are >=2.

Abstract: PURPOSE: To make possible high-speed operation by separating a wavelength- division multiplex spectrum whose a signal or a channel is received into every signals with different wavelengths. CONSTITUTION: Optical WDM(wavelength-division multiplex) signals of lots of wavelengths or channels are applied to a wavelength separator 32 through an optical fiber 30.

Optical fibers 42, 44, 46 and 48 output individual optical wavelengths at the output ports of the separator 32 to a detecting means 50 including individual optical detectors in an array. Those detectors are a high- speed optoelectric converting means. An access means 52 is selectively started for these optical detectors so as to access the individual wavelengths.  In an arbitrary moment or in an arbitrary epoch, only one optical detector detects an electric pulse signal and passes it to an output port 52. A packet controller 53 generates a control signal for a means 51.
