Title: Active narrow directivity speaker system
Inventor: YAOITA AKIRA
IPC: H03H11/20
Filed: 1994-08-22
Abstract: PURPOSE: To provide narrow directivity by performing arrangement so as to let sound waves from a positive phase speaker and an opposite phase speaker interfere mutually with the opposite phase at the tip of a noise insulation wall. CONSTITUTION: Sound signals from an input terminal 4 are passed through a BPF 5, divided into two systems and respectively passed through phase adjustment devices 6 and 7 and level adjustment devices 8 and 9, ones are passed through a power amplifier 11 and outputted to the positive phase speaker 1 and the others are passed through a phase inverter 10 and the power amplifier 12 and outputted to the opposite phase speaker 2. For both speakers 1 and 2, the characteristics of output to a frequency and phase rotation, etc., are equal and they are mutually adjacently arranged in the same direction.  Also, the distance of both speakers 1 and 2 from the tip E is set so as to let the wave surface of the sound waves diffracted and propagated to the back of the sound insulation wall 3 overlap in mutual opposite phase relation at the tip E of the sound insulation wall 3 provided in contact with the oppositive phase speaker 2. Since the energy of the sound waves are hardly transmitted to the back to be a shadow by the sound insulation wall 3, the narrow directivity at the front is obtained.

Abstract: PROBLEM TO BE SOLVED: To eliminate thermal gradient in a wafer generating distortion inducing the defects such as dislocation, by providing a gradual thermal mass which is substantially increased as accompanied by the distance from an inner edge part at the inner part of an edge-ring. support for supporting a substrate. SOLUTION: A support structure 14, which rotates a substrate 12, has an edge ring 38 in contact with the substrate 12 at the lower surface of the outer edge part of the substrate 12. Therefore, almost entire part of a lower surface 26 of the substrate 12 is always exposed except the slight ring-shaped region in the vicinity of a substrate edge part 40. To minimize the thermal discontinuance generated at the edge part of the substrate 12 during the processing, an edge ring 38 is manufactured of the same material or the similar material as the material of the substrate, e.g. carbon silicide covered with silicon or silicon oxide or silicon. The inner part of the edge ring 38 has the thermal mass, which is gradually reduced toward the inner edge part.

Title: Apparatus for mechanically purifying waste water
Inventor: ERUNSUTO FUKUSU
IPC: B01D33/21
Filed: 1985-10-18
Abstract: Apparatus for mechanical purification of waste water has a stationary hollow shaft which is installed in a vessel for waste water and carries a variable number of hollow drum-shaped frames with pairs of filters adjacent to the openings in their sidewalls. Waste water is drawn into the interior of the frames by a pump which is connected to one end of the shaft whereby the impurities deposit at the outer sides of the filters. Such impurities are removed from time to time by suction heads which are adjacent to the outer sides of the filters and are connected to a single sludge pump by discrete conduits, one for each frame. The inner sides of the respective filters are then sprayed by clean water which promotes segregation of impurities and their entry into the suction heads. Indexible valving elements are provided to connect conduits for admission of clean water into selected frames with a single source of clean water and to connect selected conduits for removal of impurities with the sludge pump.

Abstract: PURPOSE:To incline the leaf spring mount part of a support in a degree sufficient to open a leaf spring even when one piezoelectric actuator is used, by providing a constriction to the support. CONSTITUTION:This printing head has a constriction 23. The constriction 23 is formed by providing a groove 13a of the bottom surface 13c of a support 11. When voltage is applied to a piezoelectric actuator 21, the upper surface 13b of the leaf spring mount of the support 11 is pressed to compress the bottom surface 13c and the compression force generated is absorbed by the groove 13a. By this mechanism, the mount surface 20 of the leaf spring 15 of the support 11 inclines and the torsional quantity of the leaf spring 15 begins to increase. The elastic force of the leaf spring 15 exceeds the attraction force of a permanent magnet 12 at last and one end part 15b of the leaf spring 15 is released from a yoke attraction surface 11b and a printing hammer pin 16 performs printing.
