Title: Burner
Inventor: YAMAMOTO KATSUHIKO
IPC: F23D11/10
Filed: 1983-02-02
Abstract: PURPOSE:To perform stable combustion free of tar and power-saving combustion and to maintain the entire part of an evaporating body at a more uniform temperature so as to improve the durability of a burner by connecting a burning part to the bottomed cylindrical evaporating body preheated by an electric heater, and forming an exhaust gas passage at the bottom part of the evaporating body. CONSTITUTION:Combustion exhaust gas advances from a combustion cylinder 7 and an outer plate 13, between the side wall of the evaporating body 1 and a guide plate 9, and discharged out of a guide 11 via a passage 10 formed between the bottom part of the evaporating body 1 and the bottom part of the guide plate 9. In the process where the combustion exhaust gas flows, the side wall and the bottom part of the evaporating body 1 sufficiently receive heat, and even when power supply to the electric heater 2 is cut off, the fuel can be continuously evaporated only by the feedback of the combustion heat. The lower part of the side wall of the evaporating body 1, where the fuel hits concentrically and the bottom part thereof, receive heat particularly concentrically, and maintains the high temperature of 300 deg.C or more. Hence, adherence of tar can be suppressed.

Title: Washer
Inventor: ENOZONO TOMOMOTO
IPC: D06F33/02
Filed: 1990-01-26
Abstract: PURPOSE:To perform a noise reduced operation automatically when there is a stillness around a washer by detecting a sound around the washer, outputting a signal corresponding to the level of the detected sound, and controlling to change the operation modes of a motor in a plural stages. CONSTITUTION:A sound around a washer is detected by a microphone 6 when a motor 7 is stopped. Concretely, detection signal values outputted from the microphone 6 for 30 times every 1/60sec. are memorized for 0.5sec., during a stopping period, and the detection signal values are added to calculate its average S. The operation mode of the motor 7 is controlled to be changed based on the value of the average S of the detection signal value. For example, for the S of less than 45dB, the weak mode is set, for the S of more than 45dB and less than 50dB, the middle mode is set, and for the S of more than 50dB, the strong mode is set. The operation mode of the motor 7 is thus automatically controlled to be changed into the weak mode when there is a stillness as at night for performing noise-reduced operation, so a course selecting operation can be eliminated, and the operability can be improved.

SOLUTION: The operation part 9B anticipates whether or not there is the possibility of passing-by of a car 1 and a balance weight 2 by calculating a distance between a present position of the car 1 calculated from a pulse signal of a turning angle detector 5 and an initially set intermediate point of the lowest floor and the uppermost floor when judging that the car 1 travels by the operation part 8B when sensing an earthquake by an earthquake sensing signal of a sensor 8 inputted from an input/output interface 9A. As a result, the car 1 is stopped by being urgently decelerated at the decleration by arithmetically operating passing-by avoidable deceleration from a distance between a present position of the car 1 and a passing-by position and a speed of the car 1 when anticipated that they pass by each other.

Title: Method and device for simulating network and computer- readable recording medium recording simulation program
Inventor: USAMI YUTAKA
IPC: G06F17/00
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to simulate a circuit operation by a comparatively simple algorithm by comparing the circuit operation to the movement of particles in a pipe. SOLUTION: A closed loop circuit connecting a resistor to a current source as a particle model of constitution connecting pipes 2, 3 to a pump P, which executes a function for gathering prescribed particles per unit time from the lower pipe 2 and outputting these particles to the upper pipe 3. A function corresponding to a resistor is expressed as the difficulty of passage of particles from the upper pipe 3 to the lower pipe 2. When the inner capacity of the pipe is set up as unit volume, the number of particles in the pipe expresses the density of particles. When the density of particles is compared to voltage and the number of particles moving per unit time is compared to current, the difficulty of passage of particles on the part corresponding to the resistor R can be expressed as physical quantity. Thus circuit operation can be simulated by using such a particle model.
