摘要： An oscillation-preventing member for a stylus-tip protector is provided with a base member and a pair of leg parts integrally formed by employing a flexible sheet material. The pair of leg parts is bent at the same angle and in the same direction with respect to the base member. This oscillation-preventing member is mounted on a cartridge body, sandwiching a cartridge case from both outer sides with the pair of leg parts to prevent oscillation of a stylus-tip protector by bringing the base member into contact with part of the stylus-tip protector. This structure allows to provide an oscillation-preventing member for a stylus-tip protector, being attached/detached easily, manufactured at low costs, and configured to reliably prevent oscillation of a stylus-tip protector according to an impact.

摘要： A cooking pot 10 of the energy-saving type includes a body 12 including an inner vessel portion 14 having an open upper end and being defined by a peripheral side wall 16 and a bottom wall 18 closing a lower end of the side wall 16, and an outer peripheral shell portion 20 having opposite open ends and being disposed around the side wall 16 of the inner vessel portion 14 to form an annular space 22 therebetween. The side wall 16 and the outer shell portion 20 are connected together only at their upper ends to close an upper end of the annular space 22, so that the annular space has an open lower end. A lower end 26 of the outer shell portion 20 is disposed in a plane perpendicular to the axis of the side wall 16 and extends at least to a plane in which the underside of the bottom wall 18 lies. A lid 32 is provided for closing the upper end of the side wall 16 of the inner vessel portion 14.

摘要： Provided is a beamforming microphone system capable of reducing a processing load caused by computation of directivity and flexibly setting an area where sound is picked up.
A beamforming microphone system (1) according to the present invention includes: a plurality of microphone units (11); a signal processing unit (12) that processes a sound pickup signal from each of the microphone units at each predetermined time; and a storage (13) that associates, for each sound pickup area, sound pickup area information with individual-sound-pickup-area position information freely set within the sound pickup area and stores the associated information. The signal processing unit includes a position information identification unit (121) that identifies sound source position information, a signal generation unit (123) that generates the sound signal corresponding to the sound from the sound source position, and a channel assignment unit (125) that assigns an output channel, based on the individual-sound-pickup-area position information on the individual sound pickup area to which the sound source position belongs.
