摘要： A speaker of the present invention includes the following: a diaphragm that includes an inner periphery coupled to a voice coil, and a corrugation provided at the intermediate position between the inner periphery and an outer periphery; a speaker edge for supporting the outer periphery of the diaphragm; and a damping member attached to an outer peripheral part of the diaphragm outside the vicinity of an outer periphery of the corrugation. The effective vibration area of an inner peripheral part of the diaphragm inside an inner periphery of the corrugation is substantially half or less of the total effective vibration area. The damping member is configured as a damping portion by extending an overlap portion of the speaker edge overlapping with the diaphragm to the vicinity of the outer periphery of the corrugation. This configuration can suppress the vibration transmission at high frequencies to the outer peripheral part of the diaphragm outside the corrugation, allows only the inner peripheral part of the diaphragm inside the corrugation to mainly vibrate at high frequencies, and also can suppress a resonance in the outer peripheral part of the diaphragm outside the corrugation. Thus, the speaker can have both an excellent high frequency response and an excellent mid-high frequency response.
摘要翻译：本发明的扬声器包括：隔膜，其包括耦合到音圈的内周和设置在内周与外周之间的中间位置处的波纹; 扬声器边缘，用于支撑隔膜的外周; 以及阻尼构件，其附接到所述隔膜的外周部分在所述波纹的外周附近。波纹内周内的振动膜的内周部的有效振动面积大致为总有效振动面积的一半以下。阻尼构件通过将扬声器边缘与隔膜重叠的重叠部分延伸到波纹的外周附近而被构造为阻尼部分。这种结构可以抑制波纹外部的隔膜的外周部的高频振动传播，仅允许波纹内的隔膜的内周部分以高频率主要振动，并且还可以抑制外部的共振隔膜的外围部分在波纹外面。因此，扬声器可以具有优异的高频响应和优异的中高频响应。

摘要： A posture adjustment method of magnetic heads includes a method in which a magnetic head initial position adjustment apparatus 11 measures an initial position of the magnetic head 1 which was moved and adjusted, and writes the initial position into an adjustment position information shared apparatus 10, a magnetic head posture adjustment apparatus 12 reads from the adjustment position information shared apparatus 10, and information of an adjustment amount given to the magnetic head 1 when the magnetic head 1 is moved and adjusted to a final position is written in the adjustment position information shared apparatus 10, and an adjustment position as a current position of the magnetic head 1 is calculated using the initial position information and the adjustment amount information, and a method in which it is detected that one of the magnetic heads 1 reached a moving limit at which movement and adjustment of the magnetic head 1 becomes impossible, and other magnetic heads 1 which do not reach the moving limit are also moved in reverse, the moving amounts of all of the magnetic heads 1 are set equal to each other, and the magnetic heads 1 are moved in parallel to each other. As a result, it becomes easy to obtain an adjustment result of the posture of the target magnetic head 1, and it is possible to continue the adjustment operation, and to enhance the producing yield.

摘要： A character display apparatus searches through a cache means for vector font data which match character attributes of a character to be displayed to acquire the vector font data, and, when no vector font data which match the character attributes of the character to be displayed exist in the cache means, acquires the vector font data from a large-volume storage means. If there exists no corresponding luminance image data in the cache means, the character display apparatus acquires luminance image data generated from the vector font data. If there exists no corresponding display image in the cache means, the character display apparatus acquires display character image data generated from the luminance image data. The character display apparatus displays the display image which is thus acquired and which matches the character attributes of the character to be displayed on a display device.
摘要翻译：字符显示装置通过高速缓存装置搜索与要显示的字符的字符属性匹配的矢量字体数据以获取矢量字体数据，并且当没有与要显示的字符的字符属性匹配的矢量字体数据存在于高速缓存装置从大容量存储装置获取矢量字体数据。如果高速缓存装置中没有对应的亮度图像数据，则字符显示装置获取从矢量字体数据生成的亮度图像数据。如果高速缓存装置中没有相应的显示图像，则字符显示装置获取从亮度图像数据生成的显示字符图像数据。字符显示装置显示如此获取的显示图像，并且与显示装置上要显示的字符的字符属性相匹配。
