Title: Electric vacuum cleaner and its suction port body
Inventor: MORISHITA ATSUSHI
IPC: A47L9/04
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a suction port body of an electric vacuum cleaner which improves a cleaning efficiency by increasing the torque of a rotary cleaning body without lower ing the suction efficiency of dust while improving assemblability and handleability along with higher strength. SOLUTION: A rotary cleaning body 51 sprially provided with a curved blade 55 is rotatably pivoted freely in a suction chamber 29 of a case body 24 with a suction port 28 opened in the undersurface thereof. The upper surface of the suction chamber 29 is closed by a case lid body 31 in which a intake port 60 is opened to blow a suction flow to the rotary cleaning body 51 detachably mounted. The case lid body 31 is formed almost semicircular so as to be equal in distance from an internal surface facing the suction chamber 29 and from the tip of the outer circumference in the radius R of rotation of the rotary cleaning body 51. As a result, the internal surface of the suction chamber 29 to a link pipe part 35 having a communication pipe 47 pivoted thereon from the intake port 60 becomes equal in curvature to the radius R of gyration of the rotary cleaning body 51. Thus, a suction flow is efficiently blown and works in the direction of rotation to increase the torque of the rotary cleaning body 51 and increased strength of the case lid body 31 improves assemblability and handleability.

Title: Igniting apparatus for internal-combustion engine
Inventor: HAMAI KIYUUGO
IPC: F02P15/12
Filed: 1982-02-05
Abstract: PURPOSE:To enable to start an engine promptly even at the time of low-temperature starting of the engine, by performing a short-period, large-current ignition so that even a fuel having poor vaporizing properties is ignited in a reliable manner. CONSTITUTION:In ordinary operation of an engine, a long-period discharge is caused by shifting a selector switch 16 to a side (a) by a relay 17 and thereby applying the ignition energy accumulated in a capacitor 15 of a second igniting power source 4 via a secondary winding 11a of an ignition coil 11 after starting of discharge of ignition plugs 6 caused by the voltage induced by the secondary coil 11a. Resultantly, the specific fuel consumption of the engine is lowered. At the time of starting the engine, on the other hand, the selector switch 16 is shifted to the side (b) to impress a large amount of ignition energy in the capacitor 15 through low-speed rotation of the engine directly across the electrodes of the ignition plugs 6. By thus performing a short-period, large-current ignition, it is enabled to ignite even a fuel having poor vaporizing properties and to improve the engine starting performance at the time of low-temperature starting of the engine.
