Title: Buff
Inventor: MIYAOKA ATSUSHI
IPC: A46B13/02
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To bring an outer peripheral end part into surface contact with it in a condition of being deformed along a surface of a work object, and prevent the formation of a filament flaw on its surface by forming the outer peripheral end part of a buff member in a bag shape. SOLUTION: In a buff, a disk-shaped buff member 1 formed of pile stitch- shaped cloth whose surface is knitted in a loop shape as fiber, is sandwiched by a disk-shaped flange 2 having an installing hole 21 to a rotary shaft (unillustrated) of a washing machine or a polishing machine or the like in the center. In the buff member 1, the outer peripheral end 11 is formed in a bag shape. By such constitution, since an outer peripheral end part 11 comes into surface contact with it in a condition of being deformed along a surface of a work object 3, there is no fear that a filament flaw is formed on a surface of the work object 3 like a conventional buff whose cutting edge is exposed to an outer peripheral end surface. Since firmness becomes stronger than when it is formed of single cloth, a sufficient polishing effect or a washing effect can be exhibited.  Since the outer peripheral end surface is folded back and is formed in a bag shape, there is no fear such as a weaving thread unties from the outer peripheral edge.

Title: Electric hot air heater with air cleaning function
Inventor: ASAI AKIHIKO
IPC: F24C13/00
Filed: 1990-08-31
Abstract: PURPOSE:To make it possible to detect the temperature of suction air promptly and accurately by means of a temperature sensor by introducing hot air sucked up from a suction port directly from a bypass passage and feeding said air to said temperature sensor without reducing the humidity of the suction air. CONSTITUTION:A temperature sensor 11 is installed to a bypass passage 4. When there exists an obstacle 12, such as wall near a hot air blowoff port 10, the hot air is collided against the obstacle 12 where the direction of the hot air is changed so that it may be absorbed into a main body case 1 from an air suction port 2. A part of the suction air passes through the bypass passage 4 where the temperature of the suction air is detected by the temperature sensor 11. When the suction temperature exceeds a preset temperature, a heating element 9 or the heating element 9 and a blower 5 come to a halt. It is, therefore, possible to prevent the heating of a dust filter 3 and the blower 5.

Title: Concentration of sludge
Inventor: SUZUKI TOMIO
IPC: C02F11/14
Filed: 1982-12-27
Abstract: PURPOSE:To enable performance of efficient concentration of sludge, by adding the proper amount of a reducing agent to sludge to annihilate filiform bacteria only exposed from flocks in said sludge. CONSTITUTION:A reducing agent in an amount of 0.1-10% in terms of chlorine based on the total of solid matter contained in sludge and required for the annihilation of filiform bacteria only exposed from flocks in sludge is added to activated sludge. Hence, the filiform bacteria exposed from blocks are destroyed while being affected by oxidizing action at first, so that effective pasteurization can be performed with the small amount of the reducing agent. By the destruction of the filiform bacteria extending around the flocks, impediment on approach between adjacent flocks is eliminated to effectively reduce sludge volume index (SVI) value. Consequently, the concentration of excess sludge and dehydration can be efficiently performed.
