Patent JP-H04183103-A (JP)
Title: Feedback circuit
Inventor: SAITO YASUO
IPC: H03F1/34
Filed: 1990-11-19
Abstract: PURPOSE:To protect the driving capacity of an amplifier itself from being reduced even when lowering the feedback resistance by providing the amplifier with a negative feedback circuit including a source follower or emitter follower. CONSTITUTION:For a one-stage amplifier 11, a feedback circuit 12 including a transistor Q2 that acts as a source follower is connected between input IN and output OUT. Here, Q3 represents a transistor that acts as a constant current source. Since source follower Q2 itself has a gain of almost 0dB, its feedback amount is determined by a feedback resistance R3. However, since the source follower can have an isolation of greater than about 40dB and a sufficiently high input impedance, the feedback circuit is a light burden for the one-stage amplifier 11 and the one-stage amplifier 11 does not reduce its driving capacity.

Abstract: PURPOSE:To take a measurement with high sensitivity by an optical heterodyne detection system without separating light to be measured and reference light spatially by performing signal processing and arithmetic operation according to an AC component obtained by amplifying an electric signal generated by converting the composite signal light of the light to be measured and reference light. CONSTITUTION:The composite signal light 13 is composed of the light 10 to be measured from an input terminal 17 and the reference light 12 generated by a frequency-stabilized power source 28 by nearly matching their polarized wave with each other by a polarized-wave holding optical fiber coupler 16. This is inputted to a photodetector 14 to obtain a beat signal. Further, this signal has its DC component removed and its AC component amplified by an AC amplifier 22 and is inputted to an arithmetic circuit 26 through a band-pass filter 23 and a digital voltmeter 24. Here, the effective value of the AC component is found and the ratio of its squared value and a value corresponding to the light power of the reference light is calculated to obtain an output showing the light power of the light to be measured.

Abstract: PURPOSE:To select and record required information, by sound recording a signal obtained from a microphone on a magnetic tape after delaying a prescribed time. CONSTITUTION:By switching a selection switch 3 to a 3b side and performing an ordinary sound recording operation, an analog signal from the microphone goes to a digital signal at a first audio conversion circuit 9, and is stored in a memory circuit 11, and after the prescribed time, it is read out and is outputted to a terminal 13, and it is changed to the analog signal again at a second audio conversion circuit 14, then, it is inputted to a sound recording amplifier circuit 4. Also, in such a state, a control switch 20 is opened, and no power is supplied to a motor 7, thereby, a no magnetic tape is fed. By constituting a device in such a way, the signal recorded on the tape at the time of starting sound recording by closing a memory recording switch 18 becomes a sound recording signal inputted before the prescribed time.

Title: Flat-shape tail cord for elevator
Inventor: KATAUE KOZO
IPC: H01B7/04
Filed: 1991-11-28
Abstract: PURPOSE:To greatly reduce the risk of generation of torsion by disposing two wire-rope strands close to one another which have sane strand structure and difference only in the stranded direction, and by enclosing at least one set of reinforcing wires therein. CONSTITUTION:The twist releasing force of a wire-rope is neutralized by disposing as a reinforcing wire one set of two wire-ropes close to one another which have strand structure and twist-pitch made same and only the stranded direction made opposite to one another. Thereby, the influence upon generation of torsion in a flat-shape tail cord due to the twist releasing force of the reinforcing wire is greatly reduced so that the torsion may be reduced greatly even when the arrangement of core wire bundles stranded within the flat-shape tail cord is unbalanced to some degree. That is, the stranded direction of of the reinforcing wire composed of right-hand stranded wire-rope 5a and left-hand stranded wire- rope 5b is made opposite to one another and two the wire-ropes are disposed as one set close to one another, thereby making it feasible to greatly reduce the risk of generation of torsion.

Title: Seizure preventing method at coil annealing
Inventor: IZAWA SHINYA
IPC: C21D1/70
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of seizure in a coil edge part at the time of batch annealing by electrostatically applying powder grains of seizure inhibitor to the whole surface of a steel strip before annealing, further applying, by spraying, a seizure inhibitor solution to the edge part of the steel strip, coiling the steel strip, and then annealing the resultant coil. SOLUTION: A steel strip 2 is cleaned in a cleaning section 3 and dried by a drier 4. After drying, the steel strip 2 is coated, by attraction, with the grains of seizure inhibitor by means of a dry electrostatic coating device 6. Then, a seizure inhibitor solution is applied to both of the edge parts of the steel strip 2 by a seizure inhibitor solution coating device 8 for edge. The steel strip 2 is heated and dried by the drier 4 and keeps considerable heat, and the flux in the seizure inhibitor solution is readily evaporated. The steel strip 2 is coiled by means of a coiler 9 and formed into a coil 10. Because of the application of the seizure inhibitor solution to the coil edge part, the falling off of the seizure inhibitor solution does not occur even at the time of handling and upending operation, and the occurrence of seizure at the edge can be perfectly prevented.
