  • Patent number: 10409196
    Abstract: An image forming apparatus includes an intermediate transferor to rotate in a predetermined rotation direction, a plurality of image bearers disposed along the intermediate transferor to bear latent images, a plurality of developing devices to develop the latent images, a plurality of developer containers to contain developers, and a plurality of conveyance paths each corresponding to a respective one of the plurality of developing devices and a respective one of the plurality of developer containers to supply the developers to the plurality of developing devices respectively. An arrangement of the plurality of developing devices in the predetermined rotation direction is configured to be changed without changing an arrangement of the plurality of developer containers. A layout of the plurality of conveyance paths is configured to be changed without changing connections between a supply source and a supply destination of the plurality of conveyance paths.

  • Publication number: 20190054258
    Abstract: A mesh nebulizer includes a main body including a recess with a shape that is open upward. The main body includes a vibration portion with a vibration surface, and a liquid supply portion that supplies the liquid onto the vibration surface. The mesh nebulizer also includes a cap that openably and closeably covers the upper portion of the main body, and a replacement member that is separate from the main body and the cap and detachably mounted in the recess of the main body in advance when the nebulizer is to be used. The replacement member includes a film mesh portion, a bottom plate portion, and a side wall portion. When the cap is closed with respect to the main body, the protrusion portion of the cap presses the bottom plate portion of the replacement member toward the bottom surface of the recess, thus positioning the replacement member in the vertical axis direction of the main body.

  • Patent number: 8541700
    Abstract: A weight scale includes weight measurement means, storage means for storing a weight measurement value along with a measurement day and time, determination means for determining whether a fluctuation range of the weight measurement value in the same day is within a predetermined reference range, and display means for displaying a percentage of days determined that the daily weight fluctuation is within the reference range. In this manner, a trend in weight change can be grasped even with the measurement of a relatively short period.

  • Publication number: 20110215384
    Abstract: In manufacturing processes of a semiconductor device including a shallow trench element isolation region and an interlayer insulating film of a multilayer structure, it is necessary to repeatedly use CMP, but since the CMP itself is costly, the repeated use of the CMP is a cause to increase the manufacturing cost. As an insulating film for use in a shallow trench (ST) element isolation region and/or a lowermost-layer interlayer insulating film, use is made of an insulating coating film that can be coated by spin coating. The insulating coating film has a composition expressed by ((CH3)nSiO2-n/2)x(SiO2)1-x(where n=1 to 3 and 0?x?1.0) and a film with a different relative permittivity k is formed by selecting heat treatment conditions. The STI element isolation region can be formed by modifying the insulating coating film completely to a SiO2 film, while the interlayer insulating film with a small relative permittivity k can be formed by converting it to a state not completely modified.

  • Publication number: 20110127075
    Abstract: An insulative coat film comprising one or two or more kinds of oxides having a dielectric constant (k) of 2.5 or smaller and expressed by a general formula of ((CH3)nSiO2-n/2)x(SiO2)1-x (where n=1 to 3, x?1) is used to form an interlayer insulation film. The insulative coat film applied by spin-coating is flat without reflecting underlying unevenness, and the heat-treated film has surface roughness of 1 nm or less in Ra and 20 nm or less in a P-V value. The interlayer insulation film containing the insulative coat film can have a wiring structure and an electrode formed only by etching without need of a CMP process.

  • Patent number: 7930021
    Abstract: A body composition measuring apparatus includes a right hand grip having electrodes to be contacted with the right hand of a subject, and a left hand grip having electrodes to be contacted with the left hand of the subject. The right hand grip and the left hand grip are disposed such that their respective axis lines overlap with each other on the same straight line. The left hand grip is coupled to the right hand grip in a freely movable manner such that the left hand grip can move in the axis line direction. This configuration allows a small-sized body composition measuring apparatus suitable for carrying along to be achieved.
