Title: Screw with thin head
Inventor: TOYOOKA TOSHIMASA
IPC: F16B35/06
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a screw not being deteriorated in screw-in function in the screw in which a head thickness is thin and a nominal diameter is small and prevent a screw from being easily loosened. SOLUTION: This screw 1 comprises a head 2 and a leg 4 formed with a thread ridge 3. In this screw 1, the head 2 having an engaging groove 10 is formed so as to be relatively thin, and a reinforcement part 20 of a tapered shape in which a head side is large and a thread ridge side is small is formed between a base face 5 of the head 2 and the thread ridge 3. Further, this screw 1 is provided with the thin head and has such a structure that a wall surface 11 to which a driver bit is engaged at least when the engaging groove 10 rotates in a screw fastening direction is made plane generally parallel to an axial line of the screw. Accordingly, the screw used for a relatively thin product can be obtained without damaging its intrinsic function. Further, since a thickness of a neck with respect to the engaging groove is not reduced by provision of the reinforcement part, the neck can be prevented from being disengaged. Furthermore, since the wall surface of the engaging groove is upright, it is not necessary to add thrust to the driver bit, whereby deflection is not generated even when used for a workpiece of a thin plate type.

IPC: H03M1/12
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a client-side modem which can make high-speed communica tion with an internet service provider(ISP) through a codec in a central office. SOLUTION: A bit mapping function 22 of a client-side modem 20, which can make high-speed communication with an incoming ISP 10 through a codec 2 in a central office CO, maps digital signals on symbols, each having bits the number of which is smaller than the maximum value decided by the number of slicing levels of an A/D(analog/digital) converter. A pre-equalizer filter function 26 maximizes the data transmitting speed in an analog subscriber's loop, by applying an approximate reverse channel response filter to mapped digital data and taking the maximum value of average transmitting power into consideration. Consequently, the quantization noise of analog signals received by means of the codec 2 becomes less, and accordingly, the analog signals are converted into digital signals having a higher incoming data speed.  A transmission spectral shaping circuit 24 causes further to further increase the incoming speed.
