Title: Toothbrush whose reciprocating distance is controlled
Inventor: FUKUBA HIROSHI
IPC: A46B15/00
Filed: 1987-12-28
Abstract: PURPOSE: To make a person possible to master an appropriate vibrational brushing by constituting a toothbrush providing a room for movement in a handle, and arranging a floating piece in the room for movement, and making the floating piece collide with the end wall of the room for movement when the speed for reciprocating motion of a toothbrush is normal, as distance of its reciprocating motion exceeds a definite range. CONSTITUTION: The toothbrush mainly comprises a brush part 10 and a handle part 11 integrally extending from this brush part 10 and bristles 12 are filled on the brush part 10. A hollow cylindrical room 14 for movement is formed in the handle part 11 and a floating piece 13 is arranged in this room 14 for movement. When the handle part 11 is held by a hand to perform so-called transverse brushing with a large stroke, namely a large distance of reciprocating motion, the floating piece 13 in the room 14 for movement collides with both end walls 15 and 16 to inform too large stroke by generating a sound of collision.  When a vibrational brushing with a small stroke is performed, the movement of the floating piece 13 becomes small and as the floating piece 13 collides with either one of the both end walls 15 and 16 or does not collide with both end walls, it can be informed that an appropriate vibrational brushing is performed.

Title: Silent sash
Inventor: HIRABAYASHI HIDEO
IPC: E06B5/20
Filed: 1991-11-22
Abstract: PURPOSE:To enable the extent of noise energy to be extinguished by installing a sound receiver for catching a voice from the outside, detecting this caught voice at a control part, and emitting another voice of opposite phase to that from a sound emitter. CONSTITUTION:A sound receiver 4 and a sound emitter 5 both are attached to the indoor side of a sash door 3 or frame 2, connecting each to a control part 7 in a control box 6 installed at the body side. When a noise is caught, it is outputted to the control part 7 from the sound receiver 4 and then inputted by this control part 7, detecting the noise, thereby judging whether it is of a constant period or not. When it is so judged as the constant period, a voice of opposite phase to this periodic sound is emitted out of the sound emitter 5, thus noise energy is absorbed. At that time, it is made able to deal with a large noise as well as to cope with even as to an voice penetrating into the room through such one as high in tightness like a double sash structure or the like. With this constitution, soundproofing performance is improved and, also the inside of the room can be made yet more quiet in this way.

Title: Surface acoustic wave device
Inventor: SHINDO HAJIME
IPC: H03H9/145
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To suppress increase of the chip and mounting areas by forming a comb-line electrode strip in an operating frequency band by through an area where a comb-line electrode excites a surface acoustic wave and an area where the excitation of the surface acoustic wave is suppressed. SOLUTION: In an operating frequency band of a surface acoustic wave device, the strip of a comb-line electrode 2 includes a 1st area where a surface acoustic wave is excited and a 2nd area where the excitation of the surface acoustic wave is suppressed. The 2nd area is included in the strip of the electrode 2 where the 1st area is formed in the direction vertical to the propagating direction of the surface acoustic wave and at a position adjacent to the 1st area. In the operating frequency band of the surface acoustic wave device, the surface acoustic wave is excited primarily in the 1st area. Thus the influence of the surface acoustic wave excited in the 2nd area can be neglected in regard to the characteristic that is required to the surface acoustic wave device. As a result, the pass band width can be controlled while the increase is suppressed for the chip and mounting areas.
