Title: Gain control circuit for phase detector
Inventor: SUTEIIBUN EICHI PETSUPAA
IPC: G01J9/02
Filed: 1991-06-17
Abstract: PURPOSE:To reduce the responsiveness of a phase detector to the amplitude change of an input signal by supplying a pair of the output currents having phase difference from the phase detector to calculate the ratio of the sum of a pair of the output currents and the difference between both output currents. CONSTITUTION:A phase detector 10 receives two input signals like the outputs of a coherent detection system using an interferometer or a modulator as an electro-optical sampler. One of the input signals is set to a reference signal and the other one of them is set to a phase or frequency modulating signal. In the interferometer, a signal to be modulated and a reference signal are obtained from one input signal and modulation is generated by a pressure signal, a light signal, an electric signal or other measurable signal. In the coherent detection system, the signal to be modulated is an input carrier wave signal modulated by data while the reference signal is a local oscillation signal. Two input signals are coupled and detected to form a pair of output currents i1, i2. The currents i1, i2 are inputted to an AGC ratio detector 20 allowing output currents I1, I2 and a control current Ic to flow.

Title: Reference voltage generator
Inventor: BRIAN KAADANHA
IPC: G05F1/46
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a hysteresis noise margin for the operation of a comparator. SOLUTION: A mechanism is provided for generating two different voltage values at high and low levels to form a noise margin. The mechanism selects a suitable level based on the output of a comparator 15. Then, the comparator 15 uses a selected reference voltage having a level a little higher or lower than a nominal reference value as a reference voltage during operation. The difference between each of the levels and the nominal level becomes an additional hysteresis noise margin. When the output of the comparator 15 is lower than the nominal reference voltage, the mechanism uses the high voltage level and when that output is higher, uses the low voltage level. Since the mechanism is separated from the comparator 15, it is not necessary to design or test any different comparator.  The mechanism can be disabled in operation by short- circuiting several nodes of the mechanism during the metal layer step of device production.

The switch 7 is connected to an AC voltage power source 8b, and a voltage is applied from the power source 8b to the conductor 2. In the insulator 4, then, the negative charge around the projection of the conductive layer 3 is eliminated, and the insulator 4 is uniformly charged with the positive charge. Thus, the space charge of the insulator 4 can be eliminated, and working property is improved.

Abstract: PURPOSE:To prevent the reduction of a high level output without damaging the quick operation of the rise characteristic by inserting a resistance and a Schottky barrier diode between the emitter of a transistor TR with a Schottky barrier diode and the earth. CONSTITUTION:A TR 1 with a Schottky barrier diode in the input stage of a totem pole circuit has the base connected to a signal source and has the collector connected to a positive power source through a resistance 12, and a resistance 13 and a Schottky barrier diode 17 are connected in series between the emitter of the TR 1 and the earth.

Abstract: PURPOSE:To perform optical path switching securely with low power consumption by forming two crossing waveguides on a substrate of an optical crystal body, etc., by diffusing metal in belts and by providing electrodes for the waveguide switching outside of them. CONSTITUTION:On an about 1mm. thickness substrate 8 made of an optical crystal body or semiconductor, metal such as titanium is vapor-deposited in belts and then diffused by a heat treatment to form two crossing waveguides of parts 2 and 3, and 1 and 4.

IPC: B41J2/395
Filed: 1987-07-10
Abstract: PURPOSE:To make it possible to provide a copper-clad electric discharge instrument and contrive a reduction in the cost of a discharge printer head member, by uniformly kneading a boron nitride powder with a sublimable organic binder. CONSTITUTION:A boron nitrid powder and a sublimable organic binder are uniformly kneaded with each other. The binder is suitably poly-alpha-methylstyrene, polymethyl methacrylate, polyethyl methacrylate or polybutyl methacrylate. In a member obtained by kneading the powder and the binder with each other, the binder is exposed to the surface, which ensures higher affinity for an adhesive and enables adhesion of a copper foil. The use of the sublimable organic binder ensures dissipation of the binder to the exterior of the system as a gas through complete thermal decomposition, so that deposition of carbon does not occur in the vicinity of an electric discharge instrument, and recording quality is enhanced.
