Title: Control method for engine equipped with supercharger
Inventor: YOSHIOKA MAMORU
IPC: F02B37/00
Filed: 1990-03-07
Abstract: PURPOSE:To prevent over-supercharging and a decrease in supercharging pressure in any operating condition by increasing the speed of opening of an exhaust gas switching valve means more, when the means is opened a little, the more the rate of change in engine speed increases. CONSTITUTION:In an engine 1 equipped with superchargers, before supercharging operation by only a main turbosupercharger 7 is switched to supercharging operation by both turbosuperchargers 7, 8, an exhaust gas switching valve 17 is opened a little to allow a part of exhaust gas to flow to a stopped sub- turbosupercharger 8 to slowly rotate the sub-turbosupercharger 8. At this time, an engine control computer 29 detects the rate of change in engine speed of the engine 1 to increase the speed of opening of the exhaust gas switching valve 17. Thus, when the engine speed fast increases, the exhaust gas switching valve is fast opened a little to prevent over-supercharging, and when the engine speed slowly increases, the switching valve is slowly opened a little to prevent an excessive decrease in supercharging pressure. A specified supercharging pressure characteristic can thus be exactly obtained in any operating condition.

Title: Method for polishing electrode for welding robot
Inventor: OKADA SHOICHI
IPC: B23K11/30
Filed: 1988-03-09
Abstract: PURPOSE:To prevent the occurrence of loss time by electrode polishing by polishing automatically welding electrodes of a welding robot by using an electrolytic polishing machine during conveying time of materials to be welded by a conveyance means. CONSTITUTION:When a welding line is started and a main body 2 is located at the welding position, the welding robot 3 is operated to start spot welding. When ten spot weldings are finished, the welding robot is separated from the main body 2 and a shuttle transfer 1 is actuated to start conveyance of the main boy 2. At the same time, a digital counter in a controller adds as N=N+1. In the case of N<99, polishing is not performed and in the case of N=99, an upper electrode chip 6a is pressed against a polishing head 7 of the electrolytic polishing machine 4 to perform polishing. At the same time when conveying is completed, polishing is also completed. In the case of N=100, in the same way, a lower electrode chip 6b is polished and resetting is made to N=0 and both upper and lower electrode chips 6a and 6b are polished every one thousand welding times. By this method, the loss time by electrolytic polishing is eliminated and smooth process control is carried out.

Title: Production of laminate
Inventor: HAYASHIDA HARUO
IPC: B32B37/00
Filed: 1995-03-14
Abstract: PURPOSE: To obtain a laminate without using an adhesive without being restricted too much by processing temp. or a processing speed by applying surface oxidizing treatment to a nonwoven fabric and extruding an extrusion laminating resin in a molten state at specific temp. to form a film and treating the surface of the film with ozone before bonding the film to the oxidizing treatment surface of the nonwoven fabric under pressure. CONSTITUTION: Surface oxidizing treatment is applied to at least one surface of a nonwoven fabric and an extrusion laminating resin is extruded in a molten state while the resin temp. just under a die is set to 180-340 deg.C to form a film and at least one surface of the film is treated with ozone. These treated surfaces are brought to a contact state to bond the film and the nonwoven fabric under pressure. For example, when the surface oxidizing treatment of the nonwoven fabric is performed by corona discharge, corona discharge density is set to 5w.min/m<2> or more. In the ozone treatment of the extrusion laminating resin, for example, ozone-containing air is continuously sprayed on the molten film from the blowoff orifices of the nozzles provided to the air gap under the die.

Thereafter, the value of the counter 101 is counted down by an instruction execution end signal ENDE 104 at each time of the end of instruction execution, and the value of the counter 101 is '0' when n-number of instructions including the user level interrupt permission instruction are executed. Consequently, the interrupt inhibition state is set again by an inverter 113. That is, interrupt inhibition/permission is easily controlled in the user level to prevent an adverse influence upon the system.

Title: Pressing machine
Inventor: GO HISAO
IPC: B23D36/00
Filed: 1990-03-06
Abstract: PURPOSE:To intend high precision control by lowering the gain of a servo feed roller to make the roller follow the motion of a fed material in pressing the fed material for keeping a relative relationship between the rotating position of the roller and the feeding position of the fed material constant. CONSTITUTION:When a pressing machine performs pressing at a timing for stopping a feed roller, a fed material is given disturbance in a delivered direction, so that the rotating speed of the feed roller 2 is changed. A sequencer 14 gives a driver 12 gain change-over signals at a timing subject to disturbance to lower the gain of a feedback control system compared with that in normal intermittent feed, so that the roller 2 follows the motion of the fed material 1. As such motion of the roller 2 can be detected by an encoder 5, the driver 12 compensates the effect of disturbance in the next intermittent feed. Also, in the next intermittent feed the gain of the feedback system is reset to an original value. In this way, even if disturbance occurs in pressing, a relative dislocation between the feed roller and the fed material is prevented.
