The present invention provides a sheet material container being made of a sheet material and including a body portion and a bottom portion that is to be disposed on a placement surface, and the sheet material including a plurality of film layers. A body portion sheet that constitutes the body portion includes a bonding portion where peripheral edge portions of the sheet materials are bonded. In a bottom surface sheet that constitutes the bottom portion, a non-adhesive region is provided in the plurality of film layers. The non-adhesive region forms a bottom filler-filled portion. The bottom filler-filled portion extends annularly around a non-filled portion, and includes at least three protruding leg portions that are to be placed on the placement surface so as to allow the container to stand by itself. The protruding leg portions protrude toward the placement surface past other portions in the bottom filler-filled portion due a leg forming portion.

A pump contains a pump unit for suctioning and discharging fluid due to electromagnetic drive of a vibration actuator. The vibration actuator includes a fixed body containing one of a coil core portion and a magnet, a movable body containing another one of the coil core portion and the magnet, and a shaft portion for supporting the movable body so that the movable body can perform reciprocating rotation. The pump unit includes a movable wall, and a sealed chamber whose volume can be changed by displacement of the movable wall. The movable body has a pressing portion which can abut against the movable wall to press the movable wall when the movable body performs the reciprocating rotation.

This vibration actuator comprises a fixed body including a coil, a movable body including a magnet, and an elastic support part that supports the movable body so as to be freely moveable with respect to the fixed body. The elastic support part has an outer circumferential part fixed to the fixed body, an inner circumferential part disposed inside in the radial direction of the outer circumferential part and fixed to the movable body, and a deforming arm part disposed between the outer circumferential part and the inner circumferential part and coupling the outer circumferential part and the inner circumferential part, the deforming arm part being elastically deformable. An attenuation part is provided across the outer circumferential part and a portion of the deforming arm part on an outer circumferential part side thereof, the attenuation part attenuating vibrations in the elastic support part when the movable body moves.

Vibration actuator and electronic device

This vibration actuator comprises a fixed body including a coil, a movable body including a magnet, and an elastic support part that supports the movable body so as to be freely moveable with respect to the fixed body, wherein the coil to which power is supplied and the magnet cooperate to cause the movable body to vibrate with respect to the fixed body. The elastic support part has an outer circumferential part bonded to the fixed body, an annular inner circumferential part disposed inside in the radial direction of the outer circumferential part and bonded to the movable body, and a deforming arm part that couples the outer circumferential part and the inner circumferential part and is elastically deformable. The elastic support part has a sealing part provided in a bonding part between the inner circumferential part and the movable body to seal the bonding part.

A pump system contains a pair of pumps each of which contains a vibration actuator vibrated by electromagnetic drive and can discharge fluid due to drive of the vibration actuator. The pump system has a vibration suppression mode in which the pair of the pumps are driven so that vibration of the vibration actuators of the pair of pumps is cancelled each other and a vibration generation mode in which the pair of the pumps are driven so that the vibration of the vibration actuators of the pair of pumps is superimposed with each other.

A vibration actuator includes: a movable body having: a disk-shaped magnet; a pair of magnetic parts fixed to both surfaces of the magnet; and a pair of spring stopper parts connected to the magnetic parts; a pair of elastic support parts connected to the spring stopper parts and configured to support the movable body; a fixing body configured to connect to the elastic support parts with a protection wall portion, a pair of annular coils and a magnetic shield disposed in this order at an outer circumferential side, and accommodate the movable body such that the movable body is capable of reciprocally vibrating in an axial direction; and a cylindrical resin case having, on a circumferential wall portion, an opening portion for wires for supplying power to the coils and configured to close upper and lower faces of the circumferential wall portion and accommodate the fixing body.

A silicon oxide-coated iron powder has a small particle diameter, can achieve high in a high frequency band, and has high insulating property. In a method for producing the powder, a silicon alkoxide is added to a slurry containing iron powder having an average particle diameter of 0.25 μm or more and 0.80 μm or less and an average axial ratio of 1.5 or less dispersed in a mixed solvent of water and an organic material containing water in an amount of 1% by mass or more and 40% by mass or less. Then, a hydrolysis catalyst for the silicon alkoxide is added to perform silicon oxide coating, the method resulting in a silicon oxide-coated iron powder having the high μ' in a high frequency band and the high insulating property.
