Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To automatically replenish only a quantity corresponding to a consumed solder so as to make a soldering work efficient and improve working property by starting, controlling a driving device for sending out a solder, using an amplified thermoelectromotive force. SOLUTION: A thermoelectomotive force which arises between a heated solder S and a brush is detected by a metallic gear 7 and a metallic member, and the detected force is amplified by being inputted into an amplifier 4. The detected force is amplified by 300 times at the first IC circuit, and then at the second IC circuit, it is amplified by 100 times when the inputted voltage exceeds a threshold corresponding to a status where a solder obtained in advance is continuously fused. The force amplified at the second IC circuit is inputted into a base of a transistor for motor driving, and the motor 1 is driven by increase of a collector current. The gear 7 of a solder S sending out device 2 is made to rotate for sending out the solder S being clamped between the gear 7 and a roll 8.

IPC: G01R21/00
Filed: 1979-07-17
Abstract: PURPOSE: To accurately detect a power-factor, by appropriately inverting the polarity of the rectified wave of a sinusoidal voltage signal depending on a logical level signal, which is generated by changing two-phase current signals detected from three-phase lines, and by effecting synthesis.  
     CONSTITUTION: The positive half wave of a sinusoidal voltage signal 1a is rectified at 1 to supply a synthesis circuit 2 and a smoothing circuit 3. A signal 4c corresponding to a positive-phase-sequence current is detected at 4 by a current transformer from two-phase current signals 4a, 4b detected from three-phase lines. The wave form of the detected signals changed at 5 to produce a rectangular-wave logical level signal 5a. In the synthesis circuit 2, the polarity of the signal 1b is inverted depending on the signal 5a for a time t 0 Wt 1  to produce a synthesized signal 2a. The mean value 3a of the signal 1b is determined by a smoothing circuit 3. The mean value of the signal 2a is divided by the mean value 3a in a divider circuit 6 to obtain an output corresponding to a power-factor. This results in accurately detecting the power-factor.

Title: Copying device
Inventor: UEDA YOSHIO
IPC: G03G21/04
Filed: 1988-04-15
Abstract: PURPOSE:To easily leave the state of a copying device as record by transferring data stored in a non-volatile memory to the outside. CONSTITUTION:When a power source is turned on, a CPU 1 reads data from a non-volatile RAM 3 and performs the initial setting of the copying device. When copying action is started, the CPU 1 writes a copying mode and the number of copies in the RAM 3 according to the state at that time. When a troubles occurs, the CPU 1 writes the contents of the troubles in the RAM 3. In case of printing out with respect to a printer C, the contents stored in the RAM 3 are transferred to the printer C through an interface 5 for serial transmission based on data transfer operation in an operating part B by means of the printing out starting signal. Thus, the setting condition, etc., of the copying device can easily be left as the record. Moreover, the operational condition of the copying device in a market can precisely be left in the record.

Title: Apparatus for separating/segregating synthetic resin material laminate
Inventor: NAITO SHIRO
IPC: B07B1/46
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To recover a cushioning material separated from a skin material by forming an air outlet opened to a separation chamber and discharging the cushioning material received in the separation chamber together with air in a drum. SOLUTION: A regulated amount of the pieces of a laminate A are introduced automatically into a drum through a conduit and a hopper. By the rotation of a rubbing member 21, the outside surface f1 in the radius direction of its spatula part 21b rubs a group of the laminate A pieces existing between this and inner surface of a sieve member 9 against the sieve member 9. By the action of both side surfaces f1 , f2 of the member 21, the group of the laminate A pieces are separated uniformly and effectively into a skin material (a) and a cushioning material (b). The separated skin material (a) remains in the sieve member 9, and the cushioning material is transferred from the meshes of the sieve member 9 to a separation chamber.  In this process, air introduced into the drum by an electric blower passes through the sieve member 9 and the separation chamber and is discharged from the first - third outlets so that drying and the fusion adhesion of the pieces with each other can be prevented while the inside of the drum is always being cooled.

Title: Control circuit of electric power reversible converter
Inventor: MAEDA KEIJI
IPC: H02P7/292
Filed: 1980-07-03
Abstract: PURPOSE:To prevent previously the occurrence of a short circuit at the AC side, by installing a zero voltage detecting circuit at the DC output side to add the circuit to the switching conditions in case the switching is given to a thyristor circuit that  gives a reversible input/output of the electric power of an AC bus bar to a motor. CONSTITUTION:When the output 8a of a pulse distributor 8 is delivered, the current flows to a motor 11 from a 3-phase AC bus bar 10 via a transformer 1 and a thyristor circuit 2. While the current flowing out of the motor 11 flows to the bar 10 via a thyristor circuit 3 and a transformer 2 when the output 8b is delivered from the distributor 8. A detecting circuit 6 detects the zero current flowing to a line 1a and then sends it to a switching circuit 14. The zero voltage is detected through a detecting circuit 13 and then supplied to the circuit 14 via the output of a voltage sensor 12 provided at the DC output sides of the circuits 2 and 3. The circuit 14 supplies the switch signal to the distributor 8 with ''presence'' of the detection signal of the circuit 6 and ''absence'' of the detection circuit of the circuit 13 or ''presence'' only in a prescribed time limit. In such way, a countermeasure is possible to the communication failure of a thyristor circuit.

Abstract: PURPOSE: To control accurately the output torque of an induction motor, by controlling feedbackwise independently of each other the excitation current and torque current inside the motor for its excitation current command and torque current command, and by making the excitation inductance and secondary resistance of the parameters of the motor follow up. CONSTITUTION: An excitation current id and torque current iq in an induction motor are sensed respectively from instantaneous values iu, iv, iw of the actual currents of the motor by a means 9 for converting three-phase into two-phase.

Abstract: PROBLEM TO BE SOLVED: To increase edge strength by nearly uniformly imparting specific surface compressive stresses over the entire surface of the sheet glass subjected to a thermal tempering treatment over the entire surface. SOLUTION: The surface compressive stress of 17 to 25kgf/mm<2> is imparted nearly uniformly over the entire surface of the sheet glass 3.

Title: Fluorescent polarization detecting method of nucleic acid amplification
Inventor: JIEEMUZU JII NADEYUU
IPC: C12Q1/68
Filed: 1995-04-18
Abstract: Fluorescence polarization methods for detection of nucleic acid amplification. A fluorescently labelled oligodeoxynucleotide probe is converted from single- to double-stranded form in a target dependent manner during amplification of the target sequence. This conformational change is accompanied by an increase in fluorescence polarization values. The iincrease in fluorescence polarization can be measured on a transient-state fluorometer in real-time during the amplification reaction without any physical manipulation of the sample. The inventive methods therefore provide a closed, homogeneous system for both amplification of target sequences and detection of amplification. Alternatively, amplification may be detected in the fluorometer after the amplification reaction is completed.
