Patent number: 5902541Abstract: Disclosed is an injection molding method for producing a shaped, hollow resin article by introducing a pressurized fluid into a molten resin mass injected into a mold cavity, wherein, during the introduction of the pressurized fluid, the temperature of at least one preselected portion of a back surface of the molten resin mass is maintained at a level which is at least 5.degree. C. higher than the temperature of a front surface of the molten resin mass, causing the fluid to flow into the molten resin mass along a line substantially corresponding to a line along which the preselected portion of the back surface extends, so that a shaped, hollow resin article produced has a hollow in a position corresponding to the preselected portion of the back surface. By the method of the present invention, the flow of the pressurized fluid introduced can be surely led to an intended portion in the molten resin mass, so that the location of a hollow in the molten resin mass can be surely controlled.Type: GrantFiled: March 12, 1997Date of Patent: May 11, 1999Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Shoji Imai, Maki Horikoshi

Patent number: 5083543Abstract: Fuel injection increasing timing occurs differently from the timing of changing an intake air flow and an exhaust gas flow, wherein the fuel injection quantity is controlled by a detected intake pressure and an engine which increases the fuel injection quantity at accelerating comprises a system for changing an exhaust gas glow of an exhaust system by a sequential turbo control and changing an intake air flow of an intake system by a dynamic effect of an intake air. The fuel supply is delayed by the fuel injection quantity increase at accelerating. This delay and pressure difference of intake air and exhaust gas by changing intake air flow and exhaust gas flow work together to prevent the air fuel ratio from fluctuating greatly, and a good engine combustion is maintained.Type: GrantFiled: January 31, 1991Date of Patent: January 28, 1992Assignee: Mazda Motor CorporationInventors: Yasuhiro Harada, Akira Kamisakamoto, Shoji Imai

Patent number: 5007147Abstract: A steplessly variable power transmission includes a load change detecting device for detecting a change speed in an engine load when an engine load zone to which a value of the engine load belongs is changed from an intermediate zone to a specific zone other than the intermediate zone. A speed ratio hold device is provided for maintaining the speed ratio at a constant value determined in accordance with the change speed in the engine load obtained through the load detecting device and for providing the speed ratio control means with the constant value of the speed ratio as a control signal. The speed ratio is fixed at a value in accordance with change speed in an acceleration pedal stroke under a kick down and engine brake conditions.Type: GrantFiled: May 22, 1990Date of Patent: April 16, 1991Assignee: Mazda Motor CorporationInventors: Shoji Imai, Yoshimi Kanemoto

Patent number: 4967976Abstract: A take-up spindle is used to wind thereon a webbing of a seat belt system. The take-up spindle has a shaft defining a slot through which the webbing may extend, a sleeve fitted externally on the shaft and defining a first slot and a second slot therethrough, and an insert filling out the first slot. Each of the first and second slots of the sleeve permits insertion of the webbing therethrough. The second slot of the sleeve serves to guide the webbing out of the sleeve.Type: GrantFiled: December 28, 1988Date of Patent: November 6, 1990Assignee: Nippon Seiko Kabushiki KaishaInventors: Osamu Kawai, Shoji Imai

Patent number: 4834045Abstract: The engine control system of the present invention comprises an engine output changing device for controlling an engine output of at least one of engine power, engine, engine torque and engine speed. At least two controls for controlling the engine output changing device are selected from a direct control device for directing detecting an actual value to which the engine output changing device is operated. A target value for the engine output changing device is set based on an amount an accelerator is operated to thereby adjust the engine output changing device to eliminate a difference between the actual value and the target value.Type: GrantFiled: July 1, 1987Date of Patent: May 30, 1989Assignee: Mazda Motor CorporationInventors: Shoji Imai, Mitsuru Nagaoka, Toshihiro Matsuoka, Kazutoshi Nobumoto

Patent number: 4328066Abstract: A tape splicing apparatus in which two tapes are quickly joined with no air bubbles entrapped by splicing tape. A drum body holds splicing tape by suction pressure applied through holes and the peripheral surface of the drum. The splicing tape is cut into segments of predetermined length upon the drum surface. The drum is then lowered to the splicing position upon stationary and movable receiving stands to press the sticky side of the tape segment against the abutting tape joint. A movable roller presses the splicing tape segment, which was initially attached along only a single line, in forward then rearward directions from the center of the joint so that no air can be entrapped under the splicing tape.Type: GrantFiled: July 3, 1980Date of Patent: May 4, 1982Assignee: Fuji Photo Film Co., Ltd.Inventors: Seiji Kiuchi, Shoji Imai
