Title: Suction port of vacuum cleaner
Inventor: FUKUOKA HIDETOSHI
IPC: A47L9/04
Filed: 1991-11-21
Abstract: PURPOSE:To prevent damages to floors and tatami mats while achieving smooth suction of large dirts by moving a rotary brush upward with an operating body through a shaft part to expand an interval between the rotary brush and the rim of a dust suction opening when the floors and the tatami mats are cleaned up. CONSTITUTION:When floors and tatami mats are cleaned up, an operating piece 15 is moved to the side of a suction port body 1. As a result, a rib 17 of the operating piece 15 moves along a hole 18 of a connecting rod so that an operation body 12 of the connecting rod advances and hence, a shaft part 10 moves above a bearing part 11, which makes a rotary brush stand by above a dust suction opening 6. At the same time, a protrusion (not shown) of the connecting rod separates from a working piece to turn OFF a control switch, putting the motor to a stop. As a result, the expansion of an interval A between the rotary brush (not shown) and a rim 23 of the dust suction opening 6 makes even large dirts hard to catch on the rotary brush thereby achieving a smooth cleaning work. There is no contact of the rotary brush with the floor and tatami mat thereby enabling the prevention of damages to them.

IPC: F24F7/06
Filed: 1986-12-23
Abstract: PURPOSE:To prevent surrounding atmosphere acting as a source of pollution from entering by a method wherein an air shutting means is arranged near a room connecting position of a discharging duct which is released when the room is used and closed when the room is not used, and clean air is supplied when the room is not used in such a degree an air supplying duct and the indoor part are kept at a slightly higher pressure. CONSTITUTION:When a clean room is used i.e. when a normal operation is performed, air shutting shutters 18 and 19 are released to open, an air shutting shutter 22 is closed and an air supplying fan 21 is operated under its stopped state. In case of non-use on a night time and a holiday and the like, an air conditioner 15 and a blowing fan 7 are stopped; thereby, the air shutting shutters 17, 18 and 19 are automatically closed to prevent surrounding atmosphere from the discharging duct form entering. Simultaneously, an air shutting shutter 22 is released to operate an air supplying fan 21, thereby surrounding atmosphere is introduced into the air supplying duct 6. This surrounding atmosphere is passed through a high performance air filter of a blowing unit 10 and is continued to be fed into the room as clean air. The amount of supplied clean air is kept at a slightly higher pressure (for example, 0.1 to 1.0 mmAq).

Title: Heat shielding pressure partition wall
Inventor: KIRIKAMI SEIICHI
IPC: F23M5/08
Filed: 1988-12-07
Abstract: PURPOSE:To reduce a temperature difference in a liner shell by introducing cooling air into intermediate chambers through cooling holes provided in an outer shell to carry out the convective cooling of honeycomb-like fins in an inner shell, discharging the cooling air in the intermediate chambers into a combustion chamber through holes provided at the backward flow ends of the inner shell, and forming a cooling air layer on the combustion chamber side of the inner shell to prevent the inner shell from being heated. CONSTITUTION:Cooling air in a cooling air chamber 3 passes through cooling holes 5 to impinge against pieces 6 and enters intermediate chambers 7. The outer circumferential surfaces of the pieces 6 are cooled by the impingement and convective cooling of the cooling air. The discharge of the cooling air from the intermediate chambers 7 into a combustion chamber 4 is carried out through discharge channels 8 provided at the circumferential ends of the pieces 6, thereby cooling the inner side surfaces of the pieces 6 and the inner side surfaces of the pieces 6 on the backward flow side. The temperature of the pieces 6 becomes high because they are directly subjected to the flame in the combustion chamber and, as a result, a thermal stress is generated by a temperature difference between the pieces 6 and an outer shell 1. Accordingly, in order to reduce the thermal stress, it is required to divide the thermal stress into the axial and peripheral directions. Therefore, the discharge channels 8 are provided linearly in the peripheral direction and in the axial direction.
