Patent number: 5269236Abstract: A method of preventing dust from adhering to a wall of a combustion apparatus, such as a furnace wall or exhaust duct, is carried out by forcing gas through a porous refractory member forming the wall. Specifically, the furnace wall or exhaust duct wall to which dust might otherwise adhere is made of a porous refractory member and gas is injected through the pores of the refractory member. In an incinerator, the refractory porous member extends around the periphery of a liquid injection nozzle, so that gas fed to the inside of the incinerator through the refractory porous member prevents flower from accumulating at the periphery of the end of the nozzle and attenuates the wake of the injected liquid so as to suppress the entrainment of dust in the liquid. In a melting furnace, the refractory porous members provide the ceiling of a slag separating chamber and the entrance of an exhaust gas duct open to the upper portion of the slag separating chamber.Type: GrantFiled: May 21, 1992Date of Patent: December 14, 1993Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Satoshi Okuno, Toshihisa Gouda, Kazuo Sato, Shizuo Yasuda, Hiroki Honda, Susumu Nishikawa

Patent number: 5269391Abstract: A control apparatus for controlling the output of a vehicle equipped with an internal combustion engine. The control apparatus includes a torque control unit and an electronic control unit, is electrically connected to various sensors for detecting the running conditions of the vehicle, and is capable of controlling, e.g., the operations of a throttle valve and an ignition plug, to thereby control the driving torque of the engine. The control apparatus calculates a reference driving torque of the engine on the basis of the vehicle speed, and also calculates a slippage of the driving wheels on the basis of a deviation of peripheral speed between the driving and driven wheels.Type: GrantFiled: December 10, 1992Date of Patent: December 14, 1993Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Masayoshi Ito, Kiichi Yamada, Katsunori Otake, Yasunobu Miyata, Tomohiro Narita, Susumu Nishikawa

Patent number: 5245542Abstract: A motor vehicle output power control system effects a slip control process for preventing the drive wheels of a motor vehicle from slipping against unstable maneuverability and a trace control process for preventing the motor vehicle from failing to make a turn due to an excessive lateral acceleration. The motor vehicle output power control system has a torque control unit for reducing the drive torque produced by the engine irrespective of controlling action of the driver. A target speed for the drive wheels is established on the basis of the motor vehicle speed, and a reference drive torque for the engine is set depending on the target speed for the drive wheels. Based on a slip of the drive wheels, a target drive torque for the engine is established. The torque control unit is controlled by an electronic controller so that the drive torque produced by the engine is equalized to the target drive torque.Type: GrantFiled: February 27, 1991Date of Patent: September 14, 1993Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Masayoshi Itoh, Susumu Nishikawa, Yasunobu Miyata
