Title: Method of controlling electric spark machining
Inventor: KOBAYASHI KAZUHIKO
IPC: B23H1/02
Filed: 1978-04-06
Abstract: PURPOSE:To improve consumption of an electrode and reducing of a performance characteristics due to irregular width of current pulses by controlling a working gap at a desired value in a method of spark machining by producing an electric discharge in the working gap between opposing work piece and the electrode. CONSTITUTION:A time width between pulses is devided into a first time division T1, a second time division T2 and a third time division T3. When electric discharges are produced within the predetermined second time division T2, a working gap is decided to be in a proper condition and a feeding of an electrode is controlled so as to maintain this condition. When the discharge is produced within the first time division T1, the working gap is increased, while, if the discharge was not produced within the first and second time divisions, the working gap is decided to be too wide and the feeding of the electrode is controlled so as to reduce the gap.

Title: Method for monitoring abnormality of spot welding electrode
Inventor: TORIGOE KIMIHITO
IPC: B23K11/24
Filed: 1988-02-25
Abstract: PURPOSE:To always monitor the state of electrodes and to prevent defective welding by measuring repeatedly electric resistance of the electrodes wearing away by spot welding and deciding these to be abnormal when variation for every measurement or its accumulated variations exceed a reference value to regrind the electrodes. CONSTITUTION:The electrodes 1 and 2 are short-circuited without sandwiching materials 3 and 4 to be welded and a measuring current is carried to calculate the resistance. When the length of the electrodes 1 and 2 decreases by wearing away, the resistance increases. In addition, when the tips of the electrodes 1 and 2 become flat and the contact areas increase, the resistance decreases. Accordingly, the state of the electrodes can be monitored from the resistance variation of the electrodes 1 and 2. At this time, although the decision is executed based on both the variation for every measurement and its accumulated variations, the decision can be executed based on only one side thereof according to conditions.

Abstract: PURPOSE:To stably operate the infurnace pressure controlling by operating the air amount flowing into the furnace from the gas pressure in the hood and skirt resistance to detect a change in the gap and adjusting the parameters of an in-furnace pressure regulator according to this. CONSTITUTION:The gas pressure detected in a hood 5 is fed to a controller 14 which in turn compares this with a set value and feeds a signal to a damper operator 15 to control the operation of the secondary damper 9 and control waste gas flow rate so that the difference thereof becomes zero. When the spacing between the furnace port and skirt 4 changes, the height H of the clearance is obtained with a skirt position meter 13 and the skirt resistance in the clearance is obtained as a function for this. An operator 16 operates the amount of air flowing into the furnace through the clearance, from the gas pressure and skirt resistance having been inputted thereon. Based on the results of this operation, the parameters of the controller 14 are adjusted. Thereby, the instabilization of the furnace pressure control system is prevented.

Title: Liquid fuel combustion device
Inventor: YOKOFUJITA MITSUMASA
IPC: F23D11/10
Filed: 1983-03-14
Abstract: PURPOSE:To normally keep pulverizing characteristic at an optimum value without a change in the pressure of an oil feed pump and a nozzle size irrespective of the size of a combustion amount, by performing intermittent injection of fuel. CONSTITUTION:When a nozle pressure is varied in a pulse-like manner, it forms so-called intermittent injection in that, in case the pressure at the inside of the nozzle is higher than an injection lower limit pressure and a pressure, injected through the nozzle is decreased, injection is stopped. In which case, a mean pressure during injection is approximately P1, and excellent atomization is conducted. Besides, only variation of frequency may suffice for setting of an injection flow rate which can be easily set to a set value. Further, even during low combustion, only reduction in frequency may similarly suffice for it, and no influence is exercised on a pulse width, namely, a nozzle pressure, whereby pulverizing characteristic is prevented from deteriorating, and evaporating characteristic can be maintained in an excellent manner. This permits pulsation phenomenon, occurring due to intermittent supply of fuel, to be easily prevented from occurring by selecting the capacity of an evaporating chamber and the resistance of a baffle plate at an optimum value.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To obtain a device that easily and quantitatively measures and evaluates number of transmission video frames that change depending on compression so as to recognize the transmission efficiency of an equipment and its system. SOLUTION: This device utilizes principles that number of transmission frames of a moving picture in an image transmission system attended with image compression changes in relation to a motion of a picture. A marker multiplexer section 1 adds a marker whose multiplexed position differs from each frame of a video going to be transmitted into a video signal, a transmitter side transmission unit 2 compresses the video image, and the compressed image is transmitted through a line 3. A marker counter section 5 extracts this marker from the video signal data that are expanded by a receiver side transmission unit 4, displays and counts the marker.  This device can easily be connected to a conventional image transmission unit provided with video signal input/ output terminals and measure the transmission efficiency because the processing required for the measurement is executed only in the video signal.
