Title: Resistance spot welding method
Inventor: MATSUYAMA KINICHI
IPC: B23K11/24
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress generation of expulsion and surface flush by detecting welding current and the voltage between tips to continuously measure the true dynamic resistance between the tips on the real time, and estimating the possibility of generation of expulsion and surface flush from the obtained pattern of the change in dynamic resistance to output the control signal. SOLUTION: After the energization is started, the welding current and the voltage between tips are repeatedly detected through an A/D converter at specified time intervals, and the detected values are substituted in the specified formula to calculate the dynamic resistance. The time rate of change of the dynamic resistance is obtained, the obtained patterns are classified to estimate the possibility of generation of expulsion and surface flush within the specified time to be determined from the delay time of the temperature pulsation relative to the current pulsation. When the possibility is present, the welding current is instantaneously decreased/increased to slightly increase the pressure of the electrode. Otherwise, the measurement is continued.  Generation of expulsion and surface flush can be estimated in real time by rapidly repeating this processing during the energization, and generation of expulsion and surface flush can approximately surely be suppressed.

Title: Treatment of fine particles in exhaust gas
Inventor: MEGA MITSUHIRO
IPC: B01D46/42
Filed: 1980-07-29
Abstract: PURPOSE: To permit the regeneration of filter by burning for making the removal of fine particles easier by spraying a powerful oxidant aqueous solution onto fine particles present in exhaust gas being collected onthe heat-resistant filter.  
     CONSTITUTION: Fine particles, e.g., carbon particles, present in exhaust gas are arrested by a heat-resistant filter filled with steel wool. When the filter 4 is clogged to a given extent, an aqueous solution of a powerful oxidant, e.g., a chlorate, a nitrate, a permangamate, etc. is jetted from a supplier at the heat-resistant filter 4 so as to adhere it to the fine particles, whereupon the fine particles take fire and are burned because the filter 4 is heated by waste heat. In this case, the temperature of ignition is lowered and the burning speed is acclerated by the powerful oxidant.

Title: Printer device
Inventor: YAMADA TAKAYOSHI
IPC: G07B1/06
Filed: 1995-04-28
Abstract: PURPOSE: To stabilize print precision and magnetic recording precision for a long period and to convey a print medium without any trouble due to a slide by conveying the print medium across an elastic member which uses a rubber member where oil hardly sticks and a magnetic head. CONSTITUTION: A rubber member consisting of a rubber composition of 100 pts. natural rubber or synthetic rubber, 5-20 pts. carbon black, and 10-30 pts. calcium carbonate which contains no plasticizer is used for a conveyor roller 4. In this case, if a plasticizer is mixed even slightly, the plasticizer dissolves preprint ink, which resticks on the roller to decrease the frictional force. When the carbon black is less than 5 pts., the wear resistance deteriorates and when larger than 20 pts., the rubber hardness becomes high, so that the frictional force will be insufficient. When the calcium carbonate is less than 10 pts., kneading operation for the rubber composition becomes inferior and when larger than 30 pts., the rubber hardness becomes larger and the frictional force become insufficient.

Title: Graphic processor
Inventor: KUMAZAKI HITOMI
IPC: G06T11/20
Filed: 1990-04-19
Abstract: PURPOSE:To obtain an area rate at a high speed without performing the division of subpixels nor counting the number of area-filled subpixels by providing an edge deciding means and a 2nd arithmetic means which calculates the area rate of each edge part picture element based on the coordinate values of two intersection, the area of a triangle, and the type of the edge respectively. CONSTITUTION:A 1st arithmetic means calculates the area S of a triangle from the difference between the coordinate values X0 and X1 of two intersections when the vector data cross the scan lines Y0 and Y1. An edge deciding means decides the type of an edge, i.e., decides whether the vector data show the right or left edge. Then a 2nd arithmetic means calculates the area rate of each unit part picture element based on the values X0 and X1, the area S, and the type of the edge. Thus the area S is obtained at a high speed. In particular, the area rate is accurately obtained in the form of an ideal numerical value at a normal vector edge part having no edge point. As a result, the area rate can be obtained at a high speed without performing the division of subpixels nor counting the number of area-filled subpixels.
