Abstract: PURPOSE:To use an engine to be placed in an operative condition desired by the user, by only manipulating a leading particular A selector and a leading particular B selector by the user to optionally change an engine characteristic relating to an ignition timing control and a combustion control. CONSTITUTION:A leading particular A selector 10 is manipulated to delay timing change an ignition timing characteristic, for instance, over five stages. An ignition device 300, changing a resistance value of its ignition timing control circuit to be set over five stages by a circuit constant changing switch 400, controls ignition timing to the set stage. While a leading particular B selector 200 is manipulated to change compression ratio to be set, for instance, over five stages. That is, the leading particular B selector 20, if it sets a number, outputs a leading particular selecting signal to a servomotor 600 to rotate it a predetermined angle. As a result, a compression ratio changing mechanism 500 is driven, and this engine continues operation by the compression ratio selected by the user. In this way, the user can select an engine characteristic into maximum 25 kinds by manipulating the leading particular selectors A, B.

Title: Vacuum cleaner
Inventor: UZAWA HIROSHI
IPC: A47L9/00
Filed: 1992-06-19
Abstract: PURPOSE:To provide an electric cleaner which allows deodorizing without lower ing sucking force of an electric blower. CONSTITUTION:When an electric blower 26 is turned ON, dust is sucked with a suction port body to be collected into a dust collection bag 16 within a dust collection chamber 13 through a suction port 62. After the collection of the dust, air flows into the electric blower 26 through a lattice hole 11 of a partition wall 12, and then, to a deodorizing chamber 35 through an exhaust air path 34 from an exhaust port 25 of the electric blower 26. In the deodorizing chamber 35, a deodorizing agent 44 rises against gravity by an exhaust air from the electric blower 26 so that it is located in the perimeter of an exhaust port 36 of the deodorizing chamber, which eliminates the possibility of increased resistance of the air path significantly. The deodorizing agent 44 performs a rotation or other motions such as movement depending on the exhaust air. This mechanism prevents dust from adhering to the deodorizing agent 44 otherwise causing a drop in deodorizing effect.
