IPC: F23D3/40
Filed: 1978-05-16
Abstract: PURPOSE: To minimize formation and accumulaion of tar-like substance at vaporizing section for improvement of combustion performance by employing a porous body composed of a special (or a particular) fibrous material.  
     CONSTITUTION: A porous body 1, which is wholly or partly composed of alumina, silica alumina or silica refractory-like fibrous material and equipped with numerous capillary tubes, is provided under a primary combustion chamber 10 with a vaporizing section 2 on top and a fuel supply section 3 (composed of spaces) on bottom. In this mechanism, a fuel supplied to the fuel supply section 3 from a fuel supply pipe 4 is sucked up the capillary tubes of the porous body 1 to be heated and vaporized at the vaporizing section 2 and supplied to a heat exchanger 12 while being mixed up and heated up together with air supplied to the primary combustion chamber 10 and a secondary combustion chamber 11 from an air supply pipe 5 through an air flow adjusting valve 6 and an air chamber 7. At that time, since the main material composing the porous body 1 has a controlling or checking effect against formation of tar-like substance, the prescribed objective can be achieved.

IPC: G11B19/28
Filed: 1987-03-13
Abstract: PURPOSE:To eliminate a pilot signal for controlling a time base by adjusting the time base by means of controlling the rotational speed of a recording disk according to an error signal corresponding to a level difference between a specified reference signal and a speed detection signal corresponding to the rotational speed of the recording disk. CONSTITUTION:At the time of a search, when a search instruction is issued, the reference signal which gradually varies from a level corresponding to the position of a signal reading means at that time to the level, corresponding to the position of a destination to be searched is generated. Then, by the error signal, corresponding to the level difference between the reference signal and the speed detection signal corresponding to the rotational speed of the recording disk, the adjustment of the time base through the control of the rotational speed of the recording disk, is performed. Thus, the time base can be favorably controlled without using the pilot signal.

Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a shredder in which a foreign matter or the like is prevented from being entered into a charge port provided in the body of the shredder. SOLUTION: The shredder is equipped with a charge port 4 which is provided in a slope 1a formed in the upper part of the body 1 and is used for charge of a shredding form, a guide path 13 for guiding the shredding form from the charge port 4 to shredding edges 6 and a cover body 2 which is slid by gravity along the slope 1a and closes the charge port 4. When the charge port 4 is closed, the side end part of the charge port 4 in the cover body 2 is allowed to about against a wall forming the guide path 13. Thereby, when the cover body is not intentionally opened at time for charging the shredding form, charging actuation of the shredding form is not performed. Further, foreign matter except the shredding form is prevented from being entered because the cover body 2 starts to always close the charge port by gravity.

Filed: 1984-03-26
Abstract: PURPOSE:To constitute an engine high in the compression ratio, by arranging a suction valve and an exhaust valve in such a way that they are arranged in diverged form with respect to a combustion chamber. CONSTITUTION:A suction passage 3 and an exhaust passage 3' are in communication via a suction port 5 and an exhaust port 5' with a combustion chamber 1, and a valve accommodating chambers 6, 6' are formed over the suction port 5 and the exhaust port 5'.
