摘要： In order to ensure high levels of insulation performance, and low cost, and have an excellent external appearance, as a ceramic constituting an insulating coating 6 being a ceramic coating layer, one with alumina as its main component, and in which the content of titanium oxide is limited to 0.01 to 0.2 percent by weight is used. Moreover, a particle size of ceramic forming the coating layer is 10 to 50 μm, and average particle size is 15 to 25 μm. By limiting the content of titanium oxide, the insulating coating 6 can be made thin, and by limiting the particle size the film thickness accuracy can be improved, thus simplifying finishing. Moreover, by mixing of titanium oxide, deterioration of the external appearance after sealing can be prevented. As a result, the above problem is solved.

摘要： To provide a rolling bearing in which a spin slippage between a rolling element and a raceway groove is suppressed, and a rolling resistance is reduced to make the torque lower, whereby the rolling elements are easily incorporated even when the bearing rings are the monolithic type. Also, to provide the rolling bearing in which the rolling elements are easily incorporated even in a state where the bearing rings of monolithic type and a retainer are assembled. After the outer and inner races and the retainer are assembled, a small groove 4 for rotating the rolling element is provided in the center of an inner raceway groove 3 within a raceway groove space. The retainer 6 is only provided in one axial pocket face 7b of a pocket 7, and the other face is opened.

The second epitaxial crystal layer is made up of the same crystals as the first epitaxial crystal layer. The (111) plane of the substrate that includes any points on the interface between the second epitaxial crystal layer and the substrate is surrounded by the element isolation insulating film in a deeper region than the second epitaxial crystal layer.

摘要： Sound reproduction is controlled so as to be heard in the optimal state for the hearing function specific to elderly people. A frequency characteristic setting portion for setting the frequency characteristics of an inputted sound signal, and a sound volume setting portion for variable controlling the volume is disclosed. The frequency characteristic setting portion changes a frequency characteristic in which a sound band including a human voice band is emphasized to a frequency characteristic in which the characteristics of a gain in accordance with a frequency gradually becomes flat with an increase in the volume set by the sound volume setting portion. As a result, the frequency band of the human voice is strongly emphasized so as to help elderly people hear it at a low volume, and, as the volume grows higher, a frequency characteristic is changed to a flatter frequency characteristic, thereby making it possible to output easy-to-hear sound while reducing inconvenience caused by the emphasis of a specific frequency band.

摘要： A transmitting/receiving method that can easily detect an influence exerted in transmission channels at a transmitter/receiver is provided. An acquiring unit 12 acquires left audio data and right audio data of audio data received by a metadata calculator 1. An adding unit 141 then calculates added data based on an added value for a predetermined time of a sum of the acquired left audio data and right audio data. Similarly, a subtracting unit 142 calculates subtracted data based on an added value for predetermined time of a difference between the acquired right audio data and left audio data. An addition unit 17 adds the added data and the subtracted data calculated by these adding unit 141 and subtracting unit 142 to the received audio data, and a transmission unit 18 transmits the audio data to which the added data and the subtracted data are added.
