Abstract: The present invention provides a gas analyzer that can be miniaturized and detect a wide variety of gases with high sensitivity, and a method of gas analysis. A separation column 16 is configured so as to pass a sample gas together with a carrier gas through the inside thereof. A surface acoustic wave device 17 has a base material 21 with an annularly continuous annular surface formed of at least apart of a spherical surface; a surface acoustic wave generating means 22 capable of generating a surface acoustic wave that propagates along the annular surface; and a plurality of reaction parts 23 provided along the annular surface so as to change a predetermined physical quantity of the surface acoustic wave in response to the components of the sample gas. The surface acoustic wave device 17 is arranged so that the sample gas passing through the separation column 16 is reacted with the reaction parts 23.

Abstract: A mounting board of a camera module of a mobile phone is screwed to an outer cover through cushions formed of rubber, sponge or the like. A solid state imaging device and an optical unit of the camera module are contained in an opening formed in the outer cover and do not contact the outer cover. The mounting board is connected to a main substrate through a flexible board. Accordingly, even if the mobile phone is dropped down, the camera module is prevented from breakage by the vibration or the shock applied to the mobile phone, because the vibration and the shock are not transmitted to the camera module directly.

Abstract: A developing device includes a developer holding member that carries a developer; an upper developer housing section that houses the developer; a lower developer housing section that has a bottom surface lower than a bottom surface of the upper developer housing section and houses the developer; a toner supply section that includes an upper toner supply part, a lower toner supply part, and a toner transport section; an upper conveying section that includes a rotation shaft, a first conveying member, a second conveying member, and a diameter direction conveying part; and a lower conveying section that conveys at least one of the developer and the toner in a direction opposite to the conveying direction by the first conveying member.

Abstract: A member for agitating and conveying a developer, includes: a rotation shaft that rotates in a given direction; a spiral-shaped conveying member that is disposed on an outer circumferential surface of the rotation shaft; and conveys a developer in a shaft direction of the rotation shaft; a protruded agitation section that protrudes, with a gap from the rotation shaft, from the spiral-shaped conveying member toward an upstream side in a developer conveying direction; and agitates the developer; and a diameter directional conveying section that is disposed between adjacent spires of the spiral-shaped conveying member; is disposed in a downstream side in the developer conveying direction with respect to the protruded agitation section; and gives a diameter directional conveying force to the developer.

Abstract: A developing unit which includes a conveying shaft; a developing conveying portion conveying a developer in an axial direction as the conveying shaft rotates; a discharge opening discharging the developer from the inner wall surface; an accumulating chamber accumulating the discharged developer; and an opening/closing member opening and closing the discharge opening due to its own weight as the rotating body rotates, and being in an open state at the developing position, an opening/closing fulcrum of the opening/closing member being at a lower end portion of the opening/closing member at the developing position, the developing unit being held at a rotating body, and successively being made to oppose a developing position of an image carrier due to rotation of the rotating body.

Abstract: A developing device includes: a developer carrier; a first housing chamber; a second housing chamber; a first inflow portion; a first conveying member; a second conveying member; and a concentration detecting member.

Abstract: The image forming apparatus is provided with: an image carrier; an exposure member that exposes the image carrier and forms an electrostatic latent image on the image carrier; a developing member that develops the electrostatic latent image formed on the image carrier; and a contact-retracting unit that rotates the developing member taking a predetermined position as the rotational center, and brings the developing member in contact with or proximity to the image carrier or retracts the developing member from the image carrier.

Abstract: A developing device includes a first developer containing chamber, a second developer containing chamber, a first inflow section, a second inflow section, a first conveyance member and a second conveyance member. The first inflow section allows the developer to flow from the second developer containing chamber into the first developer containing chamber. The second inflow section allows the developer to flow from the first developer containing chamber into the second developer containing chamber. The first conveyance member conveys the developer contained in the first developer containing chamber in a first developer conveyance direction. The second conveyance member conveys the developer contained in the second developer containing chamber in a second developer conveyance direction.

Abstract: A developer vessel having: a developing agent, a second developing agent holding chamber that holds the developing agent supplied to the developing agent supporter; a first developing agent holding chamber being adjacent to the second developing agent holding chamber; a first partition that divides the first and the second developing agent holding chambers and having a second and a third opening portion; a first and a second carrying member that cause the developing agent to circulate between the first and the second developing agent holding chambers via the opening portions; a toner holding chamber being adjacent to the first developing agent holding chamber and facing the second developing agent holding chamber, and holds the toner supplied to the first developing agent holding chamber; and a second partition that has a first opening portion and divides the first developing agent holding chamber and the toner holding chamber.

Abstract: A solid state imaging device is consisted of an image sensor chip having a light receiving portion, a frame-like spacer attached on the image sensor chip so as to surround the light receiving portion, and a transparent cover glass attached on the spacer so as to close the light receiving portion. An outer periphery of the spacer is projected from that of the solid state imaging device to form a projection. Along an inner periphery of a lens holding frame, a groove is formed. When the lens holding frame is attached to the solid state imaging device to cover it, the groove of the lens holding frame is engaged to the projection of the solid state imaging device.
