Title: Combustion device
Inventor: FUNABIKI FUMIMASA
IPC: F23Q7/22
Filed: 1988-03-22
Abstract: PURPOSE:To reduce the waste of electric power caused by a size of load and a differential temperature of an ignition heater and an evaporating heater, by regulating power supply to the ignition heater corresponding to the temperature of the evaporation heater so that the ignition heater reaches a specified ignition temperature when the evaporated fuel gas reaches the ignition heater. CONSTITUTION:In the case the temperature of an evaporation heater R0 is lower than R1 when an operation switch is turned ON, simultaneously power supply to the evaporation heater begins and its temperature begins to rise. When the temperature of the evaporation heater reaches R1, power supply to the ignition heater begins, and when the temperature of the evaporation heater reaches R2, a magnetic pump is put into operation to feed fuel gas to a burner, so that ignition takes place. The evaporation heater having a rather large capacity is started first and then power is supplied to the ignition heater after the evaporation heater is pre-heated up to a temperature equivalent to R1 so as to synchronize the time at which the evaporation heater reaches a temperature sufficient for evaporating liquid fuel with the time at which the ignition heater reaches a desired ignition temperature.

Abstract: PURPOSE:To always keep the density of a developer constant, by uniformly stirring a condensed developer by a simple device. CONSTITUTION:A rotating motion of a driving source 12 is converted to a reciprocating motion by a tie rod 11 and is transferred to one end of a lever 10b of a stirring device 10. Accordingly, when a magnet 10a stuck to its other end starts a reciprocating and rotating motion, the tip of a stirring spring 9 of a magnetic material in a replenishing bottle 1 is attracted and interlocked by magnetic force generated by said magnet. The tip of this stirring spring 9 is supported and suspended by elasticity of one wire rod, and is interlocked susceptibly by a motion of the adjacent magnet 10a. Also, the elasticity which the spring itself has and magnetic force of the magnet 10a interfere mutually and the motion of the stirring spring 9 is amplified softly and greatly, and a rocking operation like a surge which executes a reciprocating motion to the left and right, too, as shown by a two point chain line, moving up and down is obtained. By this amplified rocking operation of the stirring spring 9, a condensed developer in the replenishing bottle 1 is stirred uniformly, and density of the condensed developer can be kept constant.

Title: Antivibration device of electrically-operated enclosed compressor
Inventor: MITSUI KIMIYOSHI
IPC: F04B39/00
Filed: 1982-04-26
Abstract: PURPOSE:To enable to miniaturize the compressor and at the same time reduce the vibration and noise thereof by a structure wherein leg parts fixed to the bottom part of the compression main body are supported by elastic vibration insulators and at the same time dynamic vibration absorbers comprising supporting a weight by means of an elastic support fixed onto the leg part are provided. CONSTITUTION:The compressor is rotated at a rotational frequency a little lower than the frequency of power source and large vibration is excited at said frequency. However, because the dynamic vibration absorbers 5, the primary natural resonance frequency of which is made coincide with the rotational frequency of the compressor or the frequency of power source, are installed at the leg parts 2, the dynamic vibration absorbers 5 vibrate with a phase opposite to the vibration of the compressor. Accordingly, the dynamic vibration absorbers 5 supply reaction torques to the compressor main body 1 at the installation positions of the leg parts 2 through the elastic supports 5b and the leg parts 2. As a result, the torque due to the vibration of the compressor and the torque supplied by the dynamic vibration absorber 5 deaden each other, resulting in effectively reducing the overall vibration of the compressor.

Abstract: PROBLEM TO BE SOLVED: To prevent the arithmetic throughput of some specific arithmetic processor from deterioration caused by the sinking of only the input/output processing request of the arithmetic processor by allowing a stacking means of m-stage to stack the input/output processing request in a case that the num ber of the times of failing in locking is larger than a regulated value. SOLUTION: In the case that a request ID judging means 61-1 judges the coincidence of the request ID of the input/output processing request 100-1 of the last locking failure with the request ID of the input/output processing request of a current locking failure, a failure counting means 80-1 counts up the number of the failure in locking. After then, the counted number of the failure in locking and the prescribed regulated value are compared with each other and when the counted number of the failure in locking is larger than the prescribed regulated value, the stacking means of m-stage stacks the request 100-1. On the other hand, when the counted number of the failure in locking is smaller than the prescribed regulated value, a first reporting means 90 gives a locking failure report 101-1 to the arithmetic processor 2-1.
