Title: Frequency stabilizing device for wavelength division multiplexing light source
Inventor: TANAKA KAZUO
IPC: H04B10/2507
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To significantly improve wavelength control accuracy of a frequency stabilizing device by substantially optically amplifying the amplitude of the optical signal received by means of a light receiving device by using a locally oscillating optical signal. SOLUTION: An external modulator 2 amplitude-modulates light to be modulated selected from among light rays emitted from a plurality of light sources LD1-LDn, by means of an optical switch 1 and a dispersion generator 3 gives wavelength dependence to the delay time from the reception of the amplitude- modulated optical signal to the output of the signal.  Then, after a photoelectric conversion section 4 mixes a locally oscillated optical signal outputted from the section 4 itself in the optical signal outputted from the generator 3, a light receiving device 8 having a nonlinear characteristic between the input optical signal and output electrical signal performs photoelectric conversion on the mixed signal, and controls the wavelength of the modulated light outputted from the light source, so that the phase difference of the optical signal outputted from the generator 3 becomes a prescribed reference value.

IPC: H03M1/82
Filed: 1979-07-11
Abstract: PURPOSE:To attain accurate demodulation of PCM signals by providing the D/A converter of a PCM demodulating circuit with a sawtooth wave generating circuit that rises synchronizing with sampling pulses. CONSTITUTION:To input terminal 10, a PCM signal of sampling time T consisting of sampling pulse P and the following data signal D is input and pulses P are detected by sampling pulse detecting circuit 11; and the data signal is converted, synchronizing with pulses P, by series-parallel converting circuit 12 into a parallel signal, which is stored in register 13. The output of clock generating circuit 14, on the other hand, is counted by counter 15 synchronizing with pulses P and a sawtooth wave is generated by circuit 16 synchronizing with the output of counter 15. When the digital value of register 13 coincides with the output value of counter 15, coincidence circuit 17 generates an output, which is applied to sample holding circuit 18 and the output voltage of circuit 16 at that point in time is sampled and held, so that an analog voltage that corresponds to the digital input signal can be obtained from output terminal 19.

Title: Copying machine
Inventor: JIYAN BARESU
IPC: G03G15/08
Filed: 1990-04-03
Abstract: PURPOSE: To control the quality of a magnetic image with high reliability by providing an optical density detector, so as to detect a magnetic field strength effect arising from marking grains and generate a response signal. CONSTITUTION: When a MICR mode so excited and magnetic toner grains are used, a switch 96 is closed and a reading head 100 is connected to a control circuit 98. Then, the head 100 transmits an AC control signal to the circuit 98 and an AC reference signal is transmitted to the circuit 98 from the optical density detector 102. At this time, the magnetic field strength effect generated by the marking grains after development on a recording member is detected and the above-mentioned AC reference signal is generated by a photodiode. Then, the circuit 98 processes the AC reference and control signals, to generate control signals as the functions of the AC reference and control signals, so that a voltage source 104 and a corona generator 22 are controlled.  Therefore, the generator 22 can be regulated to generate an electric charge sufficient for always holding a photoconductive belt 10 at a fixed potential. Thus, the quality of the magnetic image can be controlled over wide latitude with reliability.

Filed: 1984-05-07
Abstract: PURPOSE:To make the apparatus easy to use and to reduce the failure by forming the screw of an agitated vessel connected to a nonflush toilet into a ribbon screw revolving in one direction. CONSTITUTION:An agitated vessel 9 connected to a nonflush toilet contains screws 18, 18', and 18'' which are geared to a driving device 21, and is connected to a fermentation vessel below the vessel 9. A ventilator is connected to the fermentation vessel.

Title: Cassette loader
Inventor: NAKANISHI YASUYUKI
IPC: G11B15/32
Filed: 1989-04-11
Abstract: PURPOSE:To shorten the size between a cassette holder and a deck base by moving the cassette holder pressing a reel key before a cassette is completely moved from a cassette inserting position to a cassette loading position. CONSTITUTION:The cassette 1 held in a cassette holder 2 is moved along a guide hole by repulsive force of a holding spring 3. In the inserting position of the cassette 1, a lower corner part of the cassette holder is brought into contact with the reel key 24 to lower the reel key 24 against repulsive force of a coil spring 26 to be kept in a lower position. Afterward, the cassette holder 2 is moved, but it is horizontally moved in contact with the reel key 24 in the beginning. Thus, the reel key 24 is pressed to be moved by the cassette holder 2 before the cassette is completely moved from the cassette inserting position to the cassette loading position, and hence the size between the cassette holder 2 and the deck base 8 is reduced.

Abstract: PURPOSE:To provide a power supply circuit which can limit the sudden rise in voltage supplied to an inductive load and whose resistor or the like which consumes a power corresponding to the voltage rise need not have a large power capacity. CONSTITUTION:A control circuit 10 compares the output voltage of a power supply circuit 1 with a predetermined reference voltage and, when the output voltage exceeds the reference voltage, turns on a transistor (Tr1) 15 and makes the Tr1 absorb the excessive voltage. A bridge circuit 11 is controlled by feedback control. The bridge circuit 11 is composed of thyristors 110a-110l and rectifies a three-phase AC power. A DC reactor (CH) 12 and a capacitor (C1) smooth the rippled output power of the bridge circuit 11 to obtain a DC power. A resistive load 14 and the transistor 15 connected to the resistive load 14 in parallel are connected to the load of the power supply circuit 1 in parallel by the control from the control circuit 10 when the excessive voltage is generated and consume the power corresponding to the excessive voltage to avoid the rise of the output voltage of the power supply circuit 1.

Title: Method for inspecting density of pattern
Inventor: KOGA YUKIO
IPC: G06T1/00
Filed: 1988-04-12
Abstract: PURPOSE:To perform proper and reasonable inspection by evaluating the density of a pattern by a basic color itself which comprises the pattern, and displaying it by each original color signal of a color camera. CONSTITUTION:The reference density of each original color signal of the basic color which comprises a basic pattern based on basic color reflectance is found. And inspection is performed by comparing each reference density with the density of each original color signal of each basic color which comprises the pattern to be inspected. For example, when density difference between the pattern to be inspected and a reference pattern in each basic color and each original color signal is less than a prescribed allowable value, respectively, it is judged as adequate, and when either of the density difference exceeds the prescribed allowable value, it is judged as inadequate. In such a way, it is possible to perform accurate inspection reasonably.

Filed: 1993-04-16
Abstract: PURPOSE:To replace lining in a time of allowable abrasion limit in the husking fan device of a rice huller provided with lining on the internal circumferential face of a fan casing by providing a sensor means for detecting abrasion of lining. CONSTITUTION:A husking fan device is started to a rotate a husking fan at a high velocity. When paddy M is supplied in the center of the husking fan, paddy M collides against an abrasion-remarkable part 3 on lining 2 and chaff is husked. In such a way, when paddy M repeatedly collides against the abrasion-remarkable part 3, the part 3 is gradually abraded and holes 21 are made. A covered electric wire 5 is exposed when lining 2 reaches allowable abrasion limit. When paddy M repeatedly collides against the exposed covered electric wire 5 of fine diameter, covering of the electric wire 5 is broken and furthermore the same is disconnected. A display lamp is lighted by disconnection and it is informed that lining 2 has reached allowable abrasion limit. Thereby, lining is replaced in a time of allowable abrasion limit and therefore, the holes are prevented from being made in a fan casing.
