Abstract: PROBLEM TO BE SOLVED: To extend sound image reception range and to receive a sound image in a free direction of a listeners, face by supplying a signal to each loudspeaker, so that a sound having a sound image localized to a sound image localization position in common to plural speaker pairs is emitted. SOLUTION: Sets of loudspeaker pairs configuring a speaker group, each of which consists of a right speaker 21 and a left speaker 22 are placed inward to surround a two-dimensional circular space and each of four pairs of the speakers is placed at upper, lower, left/and right positions. A signal supply unit 10 supplies a signal to each of the speakers 21, 22. In this case, a sound source section 11 generates a monaural signal representing a sound from a sound image localized on a 3-dimensional space, the monaural signal is inputted to each right signal supply section 15 and each left signal supply section 16.  Furthermore, a sound image fixed position setting section 12 sets a sound image fixed position at which the sound image is localized on the three-dimensional space as a function of time in common to four pairs of speakers, and a signal representing the sound image fixed position is inputted to each transfer function generating section 13.

Title: Material for semiconductor substrate and its manufacture
Inventor: KAI YASUNAO
IPC: H01L23/373
Filed: 1995-12-15
Abstract: PURPOSE: To improve uniformity in heat dissipation efficiency, thermal expansion coefficient, density, and dimensional accuracy of material for a semiconductor substrate by constituting composite material composed of an alloy in which large and small crystal grains of metal having a high melting point are dispersed against each other in a mixing state and filler metal which is infiltrated into the texture of the alloy. CONSTITUTION: After wax for improving fluidity is added to high-melting-point metal powder composed of 70-85vol.% of large particles having an average particle diameter of 7-15μm and 15-30vol.% of small particles having an average particle diameter of 0.5-1.0μm, a molding tool is filled with the powder and the powder is compressed and molded to 65% of the theoretical density. Then the molded body is subjected to dewaxing calcination at 800 deg.C and secondary calcination at 1,000-1,200 deg.C. After the secondary calcination, a semiconductor substrate is obtained by infiltrating a filler into the calcined body at a temperature equal to or high than the melting point of the filler.  Therefore, the contraction of the compression-molded body after infiltration can be reduced to nearly zero without requiring contraction sintering and the need of machining work for finishing can be eliminated.

Title: Prefabricated wire ream winding drum
Inventor: KAWAI KAZUMITSU
IPC: B65H54/12
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of damage due to a sudden bending of a wire near a clamp port, and to eliminate the reduction of the wire wound variable at the time of winding a prefabricated wire ream. SOLUTION: A recessed part 25 is formed in the inside surface of a flange plate 23 of a drum 21. At the time of winding a prefabricated wire ream 1 around a drum 21, a compression anchor clamp 3 part of the prefabricated wire ream 1 is housed in this recessed part 25. Thereafter, a wire 2 is wound around a barrel 12 in the ordinary way. Since the compression anchor clamp 3 is not wound with the wire 2 around the barrel 12, a sudden bending of the wire 2 is not generated near a clamp port. Since a necessity of providing a clamp receiver for preventing a sudden bending in the inside surface of the flange plate 23 is eliminated, a dead space due to the clamp receiver is eliminated, and reduction of the wire wound variable is prevented.

Title: Method of storing gas and gas storage plant
Inventor: KODA YASUO
IPC: F17C11/00
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a method and a plant for storing gas with improved economy in storage. SOLUTION: In the plant for storing gas, a part of natural gas which flows in the distribution pipe 8 is introduced into a medium W in a generator 31 by a compressor 33 via diffusing pipe 40, elevating the inner pressure of the generator 31 while coolant from a coolant sourse 43 is continuously fed to a cooling pipe 41, cooling down the inside of the generator 31. This causes generation of hydrate H from natural gas G and the medium W which has higher density than the liquefied gas, resulting in reduction of volume of natural gas to be stored. Meanwhile thermal oil from a thermal oil sourse 44 is continuously fed to a heating pipe 42, elevating inside temperature of the generator, causing the hydrate H to separate into natural gas G and the medium W. This natural gas G is supplied to the distributing pipe 8 via route 39, 36 and 46.

Title: Multi-plunger type resin sealing apparatus
Inventor: SHIBUE HITOSHI
IPC: H01L21/56
Filed: 1991-12-11
Abstract: PURPOSE:To make it possible to decrease the cost for trial production by forming a chase for a mold into a shape by which resin molding for one transfer pot is possible to form a trial production and exchanging the chase for a mass production when the trial production is good. CONSTITUTION:Chases 3a and 3b for a top force and a bottom force of a multi- plunger type resin sealing apparatus has a structure wherein only one transfer pot 71 is taken out as trial production. Therefore, preparation of the chases 3a and 3b are easy. As an exchanging member exchanging the chases 3a and 3b in accordance with the kind of package consists of only a cavity insert 4, the cost of production is decreased. Then, when the trial production based on this is good, a chase for mass production for a number of transfer pots is exchanged for it to perform mass production. Therefore, expense for trial production is decreased and a period from trial production to mass production can be shortened.
