Title: Output voltage control system for polyphase cycloconverter
Inventor: KOTAKI KENJI
IPC: H02M5/27
Filed: 1986-06-10
Abstract: PURPOSE:To improve an input power factor without depending on kinds of loads and so on by determining a correction voltage for improvement of input power factor depending on a difference between an output voltage possible for a cycloconverter to output and an amplitude calculated from each required phase load voltage. CONSTITUTION:Input transformers 21-23 for cycloconverter are connected with a three-phase power source 20. Thyristor rectifiers 11-13 are connected with a secondary side of the transformers 21-23. An input side voltage of the power source 20 or transformers 21-23 is detected by an instrument transformer 71 and inputted to a computing element 81 of a voltage correcting and setting circuit 8. The computing element 81 calculates a maximum output voltage of the cycloconverter. Also, a computing element 82 calculates a voltage based on an amplitude of voltage signal involved with setting of an output value of each phase cycloconverter. A difference between these voltages is obtained as a correction voltage by a subtractor 83 and said correction voltage is added to a voltage command value and then given to firing angle regulators 51-53.

Title: Fan motor controlling method in combustion controller
Inventor: SAKATA TAKESHI
IPC: H02P29/00
Filed: 1984-07-02
Abstract: PURPOSE:To shorten the responding time by superposing a correction amount which increases as time is elapsed when a deviation between a set rotating speed and the actual rotating speed is out of a set range in positive or negative direction with respect to the set rotating. CONSTITUTION:Comparators CMP1, CMP2 output ''H'' when a rotating speed signal Vrpm is the upper limit value Vupr or higher, and ''L'' when the lower limit value Vlwr or lower. When an exclusive OR gate 15 inputs both ''L'' or ''H'', it produces an output, and applies a correction signal Vm which increases as time to a calculator 19. The calculator 19 subtracts the signal Vm from the set speed Vso when the output of the comparator CMP1 is ''L'', adds the signal Vm to the speed Vso when the output of the comparators CMP2 is ''H'' to apply the corrected data Vc to a fan motor drive circuit 11.

Abstract: PURPOSE:To enable quick treatment of a sample capsule and avoidance of capsule collision by supplying a reversely flowing fluid generated by a reversely jett measures which is actuated based on detection of passing-through of the sample capsule, to a transport way. CONSTITUTION:A capsule 6 is transported to a lower part of an irradiation cylinder 12. The capsule 6 is irradiated by neutrons as soon as arriving at the irradiation cylinder 12. After the neutron irradiation, nitrogen gas is passed into a flow way. With this process, the capsule 6 in the irradiation cylinder rises up. When the capsule 6passes through a passing-through detector 19 of the flow way 18, a reverse jet valve 32 is opened based on detection signal of the passing-through and therewith a predetermined amount of reverse spout gas is flown in predetermined timing. At that occasion, the gas in a transport way 18 is discharged into a discharge way 26 via a hole 38 and therewith the capsule 6 having passed through the hole 38, is immediately pushed back by the reverse jet flow, is sucked to the hole 38 and finally halts there completely. Then, after radiation dose rate of the sample is monitored by a measuring gauge 24, the reverse jet valve 32 and an exhaust valve 27 are closed, and, at the same time, an exhaust valve 33 for picking-up is opened to transport the capsule 6 to an analyzing device 30.

Filed: 1988-05-31
Abstract: PURPOSE:To shorten time required for raising the light quantity of a fluorescent lamp to a prescribed one and copying time as well by applying a driving voltage to the fluorescent lamp composing a light source at a specific duty rate when copying operation starts. CONSTITUTION:In an optical system device 11, an optical sensor 2 being a light quantity detecting means is provided below a slit 10 formed on a reflector 8, and detects the light quantity of a copying lamp 1 after receiving light therefrom, which is reflected on a white board 5. Before image scanning starts and until the result detected by the light quantity detecting means 2 reaches a prescribed value, the fluorescent lamp 1 is driven at a 100% duty rate. Therefore, before the fluorescent lamp 1 reaches a prescribed light quantity, prior to starting a copying process, a voltage is applied to the fluorescent lamp 1 continuously. Consequently, the temperature of the fluorescent lamp 1 rapidly rises, whereby time required for reaching the prescribed light quantity after voltage supply to the fluorescent lamp starts, and copying time can be shortened.

Title: Control on supply amount of raw materials in calendering
Inventor: UTSUNOMIYA NAOYA
IPC: B29C43/00
Filed: 1982-08-04
Abstract: PURPOSE:To raise the response and safety of calender molding by a method in which the amounts of raw materials supplied and consumed are totally controlled and the supply amount of the raw materials is controlled every control period in such a way as to eliminate hunting caused by the delay of the feeding of raw materials supplied. CONSTITUTION:Banked amount 8 is detected by a bank sensor 9, and the excessive and short amounts (+-DELTA)Q of the banked amount are calculated by a computer 12. Since feed amounts a1-an for every pitch are calculated for every control cycle signal rc and stored in an arithmetic unit 16 into which excessive and short signals, transaction speed signal (v), and constant signal are put, the supplied amount SIGMAan of raw material 2 from a knife 10 to the tip of a conveyer 3 is obtained and summed up with each signal, and signals are sent out to a controller 17. The controller 17 sends signals to a motor 11, and thereby the knife 10 is moved, the width of the raw material 2 is adjusted, the adjusted width is at the same time fed back for the next cycle. Supply amounts for the next cycle are thus controlled and the delay of feeding can therefore be prevented.

IPC: B41J9/50
Filed: 1983-07-26
Abstract: PURPOSE:To obtain uniform quality of printing even when ambient temperature is changed by providing a printing pressure regulator and also by incorporating a temperature compensator. CONSTITUTION:A printing pressure regulator 10 is capable of freely setting the value of exciting current within a fixed range from the condition that detection voltage is not put in the negative side input terminal of a differential amplifier 33 by varying the movable terminal position of the variable resistance 42 of a voltage detection circuit 40, and therefore, printing pressures can be freely set up. A thermister 47 as a temperature compensator is provided between the voltage-dividing resistor 41a of the voltage detection circuit 40 and the variable resistor 42. In the printing pressure regulator circuit 10 of such a constitution, when the ambient temperature of printer is raised, the resistance value of the thermister 47 is lowered, and the printing pressure raised by change of mechanical characteristics due to the temperature rise is automatically restored to original optimal pressure. Uniform printing quality can thus be maintained.

Filed: 1988-06-02
Abstract: PURPOSE:To prevent the driver from becoming fatigued by shielding the human body of the driver with the use of an air curtain containing negative ions so as to make the human body alkaline and to make the autonomic nerve normal. CONSTITUTION:A high voltage generator 1 installed at a suitable position overhead of the driver is energized so as to rotate a fan motor 5 which accordingly sucks up air and blows out the same through blow-out ports formed in the peripheral edge of the generator 1. When a negative voltage is applied between electrodes 6, 7 in a hollow section of the generator 1, negative ions are generated which negative-ionize the air passing the generator 1. Air containing negative ions is blown off from a forward blow-out port 4 onto an instrument panel, canceling out positive ions coming from the front side of the driver, for neutralization.
