摘要： A personal digital assistant 1 composed of a main body 2 formed with an operation section 212; a cover body 3 which is freely attached and slides parallel to the operating section 212 from a position overlapped on the operation section side of the main body 2; and an energization spring 45 formed in the cover body 3 which applies force along a direction which maintains an opened state in an opened position where the cover body 3 has been made to slide from the main body 2. Accordingly, a sliding type personal digital assistant can be stabilized in a closed position and/or an opened position and prevent opening or closing in a midway through position.

摘要： In FIG. 2, a diameter Dd of drilling edges of a drill is selected smaller than a valley diameter d1 of a male thread of a tap portion, and an inner diameter D1 of a female thread is defined by the valley diameter d1 of the male thread. Therefore, a predetermined radial gap is formed between the male thread 30 formed by the tap portion and the drill. When a tap with the drill is reversely rotated to be pulled out from the female thread after cutting the female thread, the tap released from the restriction may defectively displace in the diameter direction upon pulling out the male thread of the tap portion from the female thread. However, the drill hardly contacts with the female thread, so that the occurrence of the defective product due to the contact is suppressed.

摘要： As shown in FIG. 1, a helical flute has a constant lead part and a gradually increased lead part. The constant lead part has an axial length ranging from 0.3xLA to 1.2xLA and includes at least entirety of a leading part, so that the cutting performance of a cutting edge at the leading part and shape of chips (curled shape, etc.) are stable. In the constant lead part, because a lead is the smallest and a helix angle is large, a rake angle of the cutting edge is large, so that an excellent cutting quality is obtained and the chips become curled well. Meanwhile, in the gradually increased lead part, because of the lead gradually increased toward a shank, the chips are rapidly discharged toward the shank. Thus, the excellent cutting performance and the chip discharge performance rendered by the gradually increased lead are highly stabilized by the presence of the constant lead part. In this way, the durability is further improved.

摘要翻译： 如图所示。 如图1所示，螺旋槽具有恒定的引导部分和逐渐增加的引线部分。 恒定引线部分的轴向长度范围为0.3xLA至1.2xLA，并且包括至少整个前端部分，使得切屑的前端部分和切屑形状（卷曲形状等）的切割性能为 稳定。 在恒定引线部分中，由于引线最小，螺旋角大，所以切削刃的前角大，因此切削质量优异，切屑变得卷曲良好。 同时，在引导部分逐渐增加的情况下，由于引线朝向柄方向逐渐增加，芯片迅速向柄方向排出。 因此，通过恒定引线部的存在，由逐渐增加的引线提供的优异的切割性能和切屑放电性能被高度稳定。 以这种方式，耐久性进一步提高。

摘要： Eight-bit digital image data of R, G and B output from an image data memory are corrected by conversion controllers to meet characteristics of a liquid crystal panel. The corrected data are input to a liquid crystal drive circuit as digital image data, and an image is displayed on the liquid crystal panel. A LUT stored in a LUT reference processor stores data (addresses) by a number that makes it possible to refer to input image digital data at one to one. A random number generator is for generating random numbers and supplying the random numbers to a round-to-integer processor as threshold value data. The round-to-integer processor compares the data referred to by the LUT reference processor with the threshold data, and carries out a round-to-integer processing.

摘要： A bit error measurement apparatus is capable of easily specifying pattern conditions which cause bit errors in an incoming signal pattern without measuring all of a test pattern by measuring a bit error rate at a selected position or region of a test pattern. The bit error measurement apparatus includes a test pattern generator which generates the test pattern for verifying the incoming signal to be tested, a verifier which receives the incoming signal and the test pattern and generates a bit error detection signal when the incoming signal and the test pattern disagree, a pattern position detector which detects a measurement region of the test pattern when receiving a synchronizing signal from the test pattern generator and generates a count enable signal corresponding to the detected measurement region, and an error counter which counts the bit error detection signal from the verifier based on the count enable signal from the pattern position detector.
