Title: Parametric loudspeaker
Inventor: AOYANAGI KAZUHARU
IPC: H04R1/34
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To emit an audible voice only into a specific three-dimensional space in accordance with the size of a reflector and to transfer the voice only to a person that needs voice information, without disturbing quiet environment by switching the presence and absence of modulation of an ultrasonic wave that is emitted from an ultrasonic resonator. SOLUTION: For instance, at the time of use in a museum, ultrasonic waves that are emitted from an ultrasonic resonator 1a are reflected on a rotational parabolic reflector 2, then proceed toward the floor and form a conical audible sound field. The audible sound field is set by adjusting the angle and position of the ultrasonic resonator in accordance with a position to look at an exhibition work. Sound absorbing material 11 that absorbs ultrasonic wave components is provided on the floor. When there is no person in an audible sound field, a reflected wave does not reach an ultrasonic sensor 3a that is a reflected wave detecting means, and it becomes a silent space. When a person enters inside the field, an ultrasonic reflected wave that is reflected from a human body reaches the sensor 3a, and an explanation regarding the work which is stored in advance in a voice signal part is emitted within the audible sound field as an audible sound. This also prevents the person from coming too close to the exhibition work at the same time.

IPC: G11B20/24
Filed: 1984-09-14
Abstract: PURPOSE:To prevent completely a switching noise from being generated in a reproduced sound signal outputted from a sample-and-hold circuit by applying sampling to the reproduced sound signal in a timing before a prescribed time from a leading edge and a trailing edge of a head switching timing pulse.

Abstract: PROBLEM TO BE SOLVED: To obtain a monolithic molding with a skin which is free from deformation or warp and also damage in the skin material and further, has superior performance as an outer appearance by first, placing the skin material between a pair of opposite right/left or top/bottom forces of a mold, then clamping the forces, and packing a molten resin as a core material by injection into a mold cavity, and further, controlling the resin pressure to stay within a set pressure range. SOLUTION: A skin material S is set at a specified position on the parting face of a mold and a gap between the forces of a mold which are arranged opposite to each other is set to a mold opening of about 1mm after holding the peripheral edge part of the skin material S, and the forces are clamped. Further, a core material Q is packed into a mold cavity 5 by injection with the addition of an estimated resin shrinkage amount due to cold setting, with the mold opening left as it is. After the completion of the packing of the resin by injection, a mold clamping and dwelling step is initiated to control the mold clamping pressure so that the resin pressure falls within a set range. In addition, the resin pressure is retained, for example, at 2-50kgf/cm<2> as a dwelling load complying with the shrinkage behavior due to cold setting.  When performing thin-wall molding, the resin pressure is set as high as about 70-150kgf/cm<2> required for temporary shaping within the time limits of 5sec. or less. After that, the resin pressure is maintained at approx. 2-50kgf/cm<2> which is a required level for dwelling.
