IPC: G06Q10/04
Filed: 1986-06-20
Abstract: PURPOSE:To cope even with phenomenon varying momentarily by providing the time attribute to a fact and having collation between the fact varying momentarily and the conditional part of a rule group. CONSTITUTION:A group of facts having time attributes are collated with the conditional part of a group of rules and the rule executing part is carried out according to the rule application probability. This action is repeated until no fact to be collated exists any more. That is, a memory device 8 storing a group of facts is provided together with a memory device 9 storing a group of rules. For the group of facts, the time attribute is given to the fact so that a fact is shown as a time function. In the same way, the time attribute is also provided to the conditional part of the rule group. Thus this rule base device is applicable even to such a system where a fact varies momentarily.

Abstract: PURPOSE:To suppress the pulsating torque of the motor apparatus by directly connecting the DC input side of two sets of DC/AC power converters in parallel and setting the excessive reactances of two sets of three phase AC windings of the commutatorless motor higher than a specific value, thereby eliminating the interpole reactor. CONSTITUTION:Power converter 105a (A group) and 105b (B group) are fired in the sequence indicated in the items (B)-i, (B)-ii, the internal elecromotive force waveforms in the groups A and B are shown in Fig.(A), the input side DC voltage waveforms of the power converter are shown in Fig.(C), in which the waveforms are pulsated at every 60 deg.. The V phase winding current waveforms of the groups A and B are shown in the items (D)-i, (D)-ii, and the waveforms are affected by the magnitude of the excessive reactance la of the AC winding. Accordingly, the excessive reactance la is set so that the value of (omegala.Ia/Ea) is higher than 5%. Thus, line current becomes consecutive as indicated by one-dotted broken line in Fig.(D). If the value of the excessive reactance la is suitably increased, it becomes as indicated by solid line as smooth waveform.

Inventor: ISHIHARA HIROSHI
IPC: F24H3/04
Filed: 1992-06-05
Abstract: PURPOSE:To provide a hot air heater in which a difference in distribution of indoor air temperatures between its high air temperature and low air temperature is made less and at the same time a floor color deterioration is eliminated. CONSTITUTION:This hot air heating is constructed so that upper and lower two variable vanes 17 and 35 are arranged to be rotated downwardly at a hot air blowing port 3 as a heating capability us weakened and they are constructed so that a lower front end of the lower variable vane 35 is projected more forwardly than a lower front end of the upper variable vane 17 under a weak heating condition. Accordingly, the downward directed hot air during the weak heating operation is corrected at its orientation by the lower variable vane so as to cause the air flow to be directed along the floor surface, resulting in that the air is blown to have such a temperature distribution as one near that of the strong or high air blowing condition and at the same time the floor surface is not discolored.

Title: Video floppy disk recording and reproducing device
Inventor: YAMASHITA MASAYUKI
IPC: G11B19/02
Filed: 1986-06-20
Abstract: PURPOSE:To improve the operability by providing a recording discriminating means discriminating whether a track is a recorded track or an unrecorded track so as to eliminate the reproduction of noise at the movement of a magnetic head and so as to eliminate the need for the recording after the presence of recording is confirmed. CONSTITUTION:After an operating section 8 moves a magnetic head 14, a command is sent from a system control circuit 9 to a recording/reproducing changeover switch 7 to change over the control to the reproducing mode. Further, a discriminating signal discriminating a selected track is an unrecorded track or recorded track from a recording discrimination circuit 16 is inputted to the system control circuit 9, and if the track is discriminated to be an unrecorded track, the recording/reproduction changeover switch 7 is switched to the recording position and when the track is discriminated as a recorded track, the recording/reproducting changeover switch 7 is switched to the reproducing position. Thus, in moving the magnetic head 14, whether or not the track is a recordable track is discriminated and a recorded video signal is reproduced. Thus, it is not required for the operator to change over the recording and reproduction changeover switch 7 from the operating section 8 so as to improve the operativity.

Subsequently, a high frequency voltage of the oscillating part 1 is applied to the sensor part 2, and when a waterdrop adheres to the sensor part 2, the capacitance increases and the impedance drops. Next, an obtained signal component is amplified by a high frequency amplifier 3, converted to DC by a detecting part 4, and thereafter, brought to a low frequency amplification 5, and inputted to the discriminating part 6. Thereafter, when said signal component becomes larger than an offset voltage of a comparator CP1 of the discriminating part 6, it is outputted as a detecting signal. Accordingly, a malfunction caused by dust and sound is not generated, and also, the device can be obtained at low cost.

Title: Operation of blast furnace
Inventor: SUNAHARA KOHEI
IPC: C21B5/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To keep ore, reduced iron and scrap in a blast furnace as a uniform mixed heap by cancelling a segregating phenomenon in the average grain diameter ratio, with a segregating phenomenon in the apparent density ratio of the apparent density of the reduced iron and the scrap and the apparent density of the ore. SOLUTION: Mixture of the ore, reduced iron and scrap, is charged into the blast furnace. In this blast furnace operation, when Ds for average grain diameter, ρs for apparent density of the ore and Dh for average grain diameter, ρh for apparent density of the reduced iron and the scrap, are used, the conditions shown in the inequalities I, and II are to be satisfied. The difinition of the average grain diameters of the ore, reduced iron and scrap, is a weighted average. Further, the definition of the apparent density of the ore, reduced iron and scrap is (wt (g) of one grain)/(apparatus vol. (cm3) of one grain). The reduced iron is a metallic iron-containing raw material beforehand executing a reducing treatment with a process except the blast furnace.  In this way, the raw material can be charged into the blast furnace always in the uniform mixed condition in the radius direction and the iron producing quantity can be increased with the stable blast furnace operation.

Title: Gate circuit
Inventor: SHIMATANI TSUTOMU
IPC: H03K17/00
Filed: 1978-11-24
Abstract: PURPOSE:To make it possible to meausre only the width of the first single pulse by cascading flip flops in two stages and causing pulses during a time, when these flip flops are set, to pass through. CONSTITUTION:When a pulse train is inputted, the inversion output is obtained from inverter 1. As the result, flip flop 2 is set by the first H signal of input pulses. At this time, the output of AND gate 7 becomes an H signal due to outputs of flip flops 2 and 5. After that, when input pulses become L signals, flip flop 2 is set as it is, and flip flop 5 is set, and then, the output of AND gate 7 becomes an L signal. After that, even if H signal pulses are inputted, no output is generated because flip flops 2 and 5 are set as they are. Consequently, output signals are obtained only during the time of the first pulse width.

IPC: H04L27/22
Filed: 1995-06-13
Abstract: PURPOSE: To make a receiver into a low power by reducing a local oscillation signal power to be supplied to the mixer of a quadrature modulation signal demodulation circuit. CONSTITUTION: A signal distributor 1 branches a quadrature modulation signal. A 0 deg. phase shifter 2 applies 0 deg. phase shift to one of branched modulation signals and supplies it to the mixer 7. A 90 deg. phase shifter 3 whose phase shift quantity is changed applies 90 deg. phase shift to the other of the branched modulation signal. A level attenuator 6 fits the level of the modulation signal from the 90 deg. phase shifter 3 in the output level of the 0 deg. phase shifter 2. While, local oscillation signals with common mode are supplied to the mixers 7, 8. The mixer 7 generates a baseband signal of I phase that is the common mode component of the modulation signal by multiplying a supplied modulation signal by the local oscillation signal.  Also, the mixer 8 generates a baseband signal of Q phase that is the quadrature component of modulation signal by multiplying the supplied modulation signal by the local oscillation signal.
