Title: Filter for replacement and manufacturing method
Inventor: NAKAGAWA KEIICHI
IPC: F24F7/06
Filed: 2002-02-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a filter for replacement and its manufacturing method, which can inform the time of replacement surely regardless of the condition of use.  <P>SOLUTION: A film-like replacement sign 13 is formed on the side of the back face of a filter sheet 12 comprising sheet-like unwoven cloth. Since the replacement sign 13 has no air permeability, gas including smoke and the like produced by its use doesn't pass through the range B where the replacement sign 13 is formed, but passes through the other range A. Since the smoke and the like are adsorbed into the filter sheet 12 by their passing, the filter sheet 12 of the range A is discolored gradually. Since smoke and the like are not attached to the range B, the range B is not discolored, and the color of the filter sheet 12 before use is left unchanged. Through this constitution, the range B corresponding to the replacement sign 13 becomes remarkable due to the discoloring of the filter sheet 12 of the range A, informing a time for replacement of the filter with a new one.  <P>COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To remove a worked modified layer generated at grinding of the rear surface of a semiconductor wafer, without damaging the wafer. SOLUTION: A method for working the semiconductor wafer comprises the steps of first holding the wafer 22 on an adsorption table 12, and grinding the rear surface 22B of the wafer 22 by a cup-type grinding wheel 24. The method further comprises the step of polishing the rear surface 22B of the wafer 22 by a polishing cloth 42, in a state in which the wafer 22 is held by the table 12 after the grinding is finished. Since grinding is executed in a state in which the wafer is held by the table 12, the worked modified layer can be removed without damaging the wafer 22.

IPC: A47J37/06
Filed: 2002-03-01
Abstract: <P>PROBLEM TO BE SOLVED: To improve feel of use by preventing unpleasant hitting noise from occurring when opening a door.  <P>SOLUTION: In the initial step where an interlocked arm 14 starts moving towards the front side (in the left direction in the Fig.), a board moving back and forth 41 only moves between a middle stopper 31b and a rear anchor stopper 31a and thus a piston 31 does not move and a speed control device 30 is not activated. When the board moving back and forth 41 tries to further move forward after touching the rear anchor stopper 31a, the rear anchor stopper 31a is pushed by the board moving back and forth 41, in other words, the piston 31 is pushed toward the left direction in the Fig. and then the speed control device 30 is activated. Consequently, the grill door 8 only turns slowly from the halfway of the turn in its turning direction and does not fling open. Therefore, the unpleasant hitting noise generated by the grill door 8 and the device body bumping against each other can be prevented from occurring. In addition, since the speed control device 30 is not activated in the initial step of the turn, the door can be turned open swiftly.  <P>COPYRIGHT: (C)2003,JPO
