Title: Method for working curved face
Inventor: SHIOTANI KEIICHI
IPC: G05B19/4103
Filed: 1987-04-15
Abstract: PURPOSE:To simply obtain a smooth curved face within a short period of time by working the curved face while making a segment on a curved face obtained by linear interpolation between two curved faces coincide with the straight line of an edge on the axial section of a tool. CONSTITUTION:A loft curved face or a rule curved face frequently appearing in industrial products is defined by the following equation. Namely, S(u, w)=(1-u)C1(w)+uXC2(w), provided that 0<=u, w<=1 and S(u, w), C1(w) and C2(w) are vectors having respective components of orthogonal coordinate axes (x, y, z). On the other hand, a straight line connecting respective points C1(wi), C2(wi) is expressed by (1-u)C1(wi)+uXC2(wi). Thereby, a smoothly worked curved face S(u, w) can be obtained by making the straight line of an edge on the axial section of the tool coincide with the segment expressed by the latter equation. That is to say, curved face S(u, w) represented by the former equation can be obtained by linear interpolating between two curved lines C1(w) and C2(w). The drawing shows an example of arranging a tool 10 on a cylindrical substance.

Abstract: PROBLEM TO BE SOLVED: To automatically identify and display a current connected line concerning communication equipment for performing data communication being connected with a general telephone line, 'PHS(R)' or portable telephone set. SOLUTION: Concerning communication equipment 1A, a voltage Vs between lines is detected by a voltage detecting part 13 concerning the general telephone line and when that voltage value is within a specified range, the line is identified as the general telephone line but when the voltage value is less than a specified voltage value, the line is identified as a 'PHS(R)' line. Concerning the portable telephone set line, when a data terminal ready signal (ER) or transmission enable signal (CS) based on an RS232C serial interface standard from a modem 5 is received, the line is identified as the portable telephone set line. On the basis of this identification, the line is displayed on a display part 21 or on-screen display is performed on a monitor part 6 through a video processing part 22. Besides, on the basis of the said identifying function, the priority of line connections can be set by a setting part 19. When this priority is set, these data are stored in a memory part 20.

Title: On-vehicle tunable radio receiver to area channel
Inventor: ZEN HEIKOU
IPC: H04B1/06
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To allow the receiver to receive continuously a broadcast program without any channel operation by selecting an optimum modulation section bringing a highest DC level from a set of modulation frequencies extracted through the comparison of DC voltages. SOLUTION: A broadcast signal is received by an antenna 12 and a main tuner 14 that is tuned to an optimum modulation frequency given from a reception controller 20. A signal resulting from an output of the tuner 14 is given to an intermediate frequency amplifier 16, where the signal frequency is converted into an intermediate frequency and the resulting signal is fed to an audio detector 18. The detector 18 detects an audio signal from the received signal and produces a DC voltage proportional to a peak level of the detected audio signal. The DC voltage is used for a gain control signal which changes a gain of the tuner 14 to allow the output DC voltage level of the detector 18 to be constant.  Then DC voltages from detectors 18, 28 are compared and an optimum modulation frequency bringing a highest DC level from a set of extracted modulation frequencies is selected and a corresponding audio signal to the optimum modulation frequency is received.
