A wireless transmitter (300) communicates with a wireless earphone (100) to obtain remote communications. The wireless earphone includes: a wireless network card (30′) complying with the 802.11a/b/g standard, for receiving data packets and unpacking them to release digital audio signals; a control processor (20′) connected with the wireless network card, for dealing with the digital audio signals; and a digital-to-analog converter (50) connected with the control processor, for converting the digital audio signals to analog audio signals. The wireless transmitter has a structure similar to that of the wireless earphone, except that the wireless transmitter has an analog-to-digital converter (10) instead of the digital-to-analog converter.

An ink for ink jet recording and an ink jet recording method which realize an image quality of laser printer on a plain paper in a one-pass printing mode under conditions of a volume of an ink droplet ejected being 5 to 43 Pico liter, a velocity of an ink droplet being 6 to 20 m/sec, frequency of 1 kHz and resolution of 300 dpi or more. The ink for ink jet recording is a penetrating type ink which comprises (1) at least one humectant selected from glycerin, 1,3-butandiol, triethyleneglycol, 1,6-hexanediol, propyleneglycol, 1,5-pentanediol, diethyleneglycol, dipropyleneglycol, trimethylolpropane and trimethylolethane, (2) colorant contained in the amount of 6 % by weight or more, (3) a polyol having 8 to 11 carbon atoms and glycolether, and an anionic surfactants or non-ionic surfactants, the ink has viscosity of 5 mPa.s or more at 25° C. and a surface tension of 40 mN/m or less.

A tone transformation apparatus of the present invention extracts or generates a signal Z[i, j] according to a pixel value of a pixel [i. j] of an original image or a pixel value of its immediate neighborhood. Further, it extracts or generates a signal ZL[i, j] according to a pixel value of a neighborhood area of the pixel [i, j]. A transformation gain k for the pixel [i. j] is determined according to these signals Z, ZL. For the tone transformation, a color component or the like of the pixel [i, j] is multiplied by the transformation gain k for the pixel [i. j].

An ink containing at least two coloring materials of a first coloring material and a second coloring material, wherein the first coloring material is a compound represented by the general formula (I), and the second coloring material is a compound represented by the general formula (II):

According to the present invention, a novel phthalocyanine compound having a specific structure is provided, and an ink, an inkjet recording ink, an inkjet recording method and a method for improving preservability of a formed image, each using the compound, are also provided. The novel phthalocyanine compound of the present invention has a sufficiently high fastness to light, heat, humidity and active gases in the environment and by using an ink, particularly inkjet recording ink, containing the phthalocyanine compound, an image having high fastness to light and ozone gas in the environment can be formed.

A resonator 13 is provided including a resonating body 13 which is vibrated by intake air pulsation in an intake system 5, a volume chamber 14 connected through the resonating body 13 to the intake system 5, and a neck section 16 through which an interior space 15 of the volume chamber 14 is communicated with outside. The interior space 15 of the volume chamber 14 and interior of the intake system 5 are partitioned by the resonating body 13. The resonator is so set that a sound pressure in a certain frequency range is released from the neck section 16 to the outside under vibration of the resonating body 13. With this, the sound pressure characteristics of air intake sound can follow a rise in engine speed.

The present invention provides a magenta recording ink composition including at least a solid solution pigment (A) containing quinacridone, a lake pigment (B) having a xanthene structure, an aqueous solvent, and water, wherein the solid solution pigment (A) has visible light absorption peaks at wavelength ranges of from 510 nm to 530 nm and from 540 nm to 560 nm, and a mass ratio (B/A) of the lake pigment (B) to the solid solution pigment (A) falls within the range of 0.1 to 5.

The invention relates to a method for performing self-shot soft light compensation on basis of screen luminance. After a shutter is pressed, the screen luminance is adjusted, light compensation is performed on a human face, then a camera hardware is driven for taking a picture, time of the uniform speed adjustment of the screen luminance from minimum luminance to maximum luminance is no less than preset adjustment time, the screen luminance is adjusted to simultaneously display one of patterns with various non-pure colors, and a soft light lamp with different effects is formed according to pattern selecting set so that soft light compensation is performed on the human face. By means of the method for performing self-shot soft light compensation on basis of screen luminance, own screen luminance of a mobile device is improved, colors and patterns with various soft lights can be set on a screen, thereby, self-shot pictures that are photographed are good in colors and excellent in human skin color, multiple matching modes are provided, and a user can solve problems caused by environmental lights through selection.

It is an object of the present invention to provide a recording ink comprising at least a color material particle which is an inorganic pigment particle coated with one of organic pigment and carbon black, a polymer particle, a water soluble solvent and water, an ink cartridge, an inkjet recording method, an inkjet recording apparatus and an ink record that utilize the recording ink respectively.
