摘要:
Voice coil body of a loudspeaker is provided at the outer circumferential wall surface with a supporting section. Diameter of the inner circumference of suspension holder is greater than outer diameter of the voice coil body while diameter of the inner circumference of diaphragm is greater than diameter of the inner circumference of suspension holder for facilitating a gluing of the inner circumferential end of suspension holder and the inner circumferential end of diaphragm on the supporting section and to the voice coil body. By so doing, harmonic distortion of a loudspeaker can be further reduced.
摘要:
The speaker has a frame, a magnetic circuit, a voice coil body and a diaphragm. The magnetic circuit is disposed inside of the frame to form a magnetic gap. The voice coil body is disposed movably in the magnetic gap. The diaphragm is coupled to the voice coil body by an inner periphery edge thereof and to the frame by an outer periphery edge thereof. The outer peripheral surface of a convex portion provided on a bottom of the frame is at least either being brought into contact with or in proximity to the magnetic circuit. The configuration can provide the speaker with excellent heat dissipation characteristics.

There is disclosed a small-size speaker in which distortion is not easily caused when a diaphragm vertically movers for sound reproduction. The speaker includes: a bottom-equipped cylindrical frame having an opening at the top; a magnetic circuit arranged on the inner bottom of the frame; a voice coil whose coil portion is arranged in a magnetic gap of the magnetic circuit; a diaphragm arranged at the opening of the frame and its inner circumference is fixed to the voice coil while its outer circumference is fixed to the frame via a first edge; and a support body having one end fixed to the side of the diaphragm having the magnetic circuit and the other end fixed to the vicinity of the magnetic circuit via a second edge. The first edge has a shape substantially similar to the shape of the second edge with respect to the boundary between the first edge and the second edge.

Disclosed is a speaker configured to reduce or eliminate distortions when a diaphragm thereof vertically moves in sound reproduction and which can be downsized. This speaker includes: a cylindrical frame having a bottom face and an open top; a magnetic circuit disposed on a inner bottom face of the frame; a voice coil having a coil portion thereof disposed in a magnetic gap of the magnetic circuit; the diaphragm disposed in an opening of the frame, and fixed to the voice coil along an inner periphery thereof, and to the frame via a first edge along an outer periphery thereof; and a support fixed to the diaphragm on the side of the magnetic circuit at one end and to the vicinity of the magnetic circuit via the second edge on the other end. The first edge is substantially analogous to the second edge in shape with respect to the boundary therebetween.

An image processing apparatus is provided which efficiently saves power by preventing unnecessary transitions from a power saving state to a non-power saving state. The image processing apparatus processes image data, and is capable of switching an operation mode between (a) a power saving mode in which power consumption is suppressed and (b) a non-power saving mode in which power is more consumed than in the power saving mode. The image processing apparatus includes: a foot sensor and a computing process section for which detects (i) a first conforming state where a person is present within a predetermined distance range in front of the image processing apparatus and (ii) a second conforming state where a direction, in which the person faces, is within a predetermined range which allows an assumption that the person is faces a front side of the image processing apparatus; and a sub control section which controls the operation mode to be switched from the power saving mode to the non-power saving mode, when the first conforming state and the second conforming state are detected in a state where the operation mode is set to the power saving mode.

A main controller controls drive of an LSU for irradiating laser light onto a charged photoreceptor, based on control data read from a non-volatile memory. The main controller causes the LSU to irradiate a beam of light onto the photoreceptor so as to form on the photoreceptor an electrostatic latent image corresponding to an image to be formed. A controlling section reads through an image reading section control data from the non-volatile memory at a different timing from a timing at which the main controller controls the LSU. The controlling section controls drive of the LSU based on the read control data.
摘要:
When carrying workpieces from a loading area in which the workpieces are handled into a heat treatment furnace to make the workpieces subjected to a heat treatment process using a predetermined process gas, the loading area is evacuated and controlled at a predetermined low negative pressure. An exhaust for evacuating the loading area is connected to the loading area, and a controller controls the exhaust so that the loading area is maintained at the predetermined low negative pressure. A specific gas and particles contained in a gas discharged from the loading area are removed by filters.

The present invention provides a skin test method for predicting the formation of spots in the skin. This method judges skin to be susceptible to the formation of spots in the case expression in the epidermis of MCP-2 gene, a polynucleotide capable of hybridizing under highly stringent conditions to mouse AK012157 gene, human FLJ21763 gene or rat S74257 gene, or Mcp9, Mcp10, Isg15, Usp18, Oas12, Gbp2, Gtpi, Ifi47, Igtp, Tgtp, Sprr2A, Krt2-6b, Cdk5rap2, Mef2C, Gsta4, Osf2, Tnc, Igfbp6, Ppicap or Mm. 74656 gene, is increased as compared with normal expression in the epidermis.
