Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To form a small diameter grinding wheel into a target shape by providing a grinding wheel diameter measurement means for measuring a grinding wheel diameter in the axial direction of a main spindle at a plurality of positions with a measurement instrument after a truing process on the operation of a truing means. SOLUTION: After a truing process is finished, the diameter of a small diameter grinding wheel 26 is measured. That is, the diameter is measured at a plurality of positions along the axial direction of the small diameter grinding wheel 26. In this case, measurements are taken at three positions P1, P2 and P3 and grinding wheel diameters d1, d2 and d3 are respectively calculated for storage in a memory 37b. When the values of d1, d2 and d3 are all identical, a truing cycle is ended under the judgement that the side of the small diameter grinding wheel 26 is formed in parallel to the rotational axial line thereof and the small diameter grinding wheel 26 is trued to a target shape.

Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce tone quality deterioration with a little operation quantity by representing a pulse position as a prescribed number of bits and providing a sound source quantization part in which the pulse amplitude is predetermined based on the pulse position. SOLUTION: An adaptive code book circuit 500 predicts a pitch and outputs a predictive error signal to a sound source quantization circuit 350. The sound source quantization circuit 350 quantizes one or more pulse positions into a prescribed number of bits and outputs its index to a multiplexer 400. At this time, the amplitudes of the one or more pulses are predetermined based on their positions. Also a gain quantization circuit 365 to which the information on the amplitudes and the positions is outputted selects a gain code vector for the selected sound source code vector. A weighting signal calculation circuit 360 reads a code vector corresponding to the index and determines a driving sound source signal and outputs it to an adaptive code book circuit 500.  Then the weighting signal calculation circuit 360 calculates a response signal for each sub-frame and outputs it to a response signal calculation circuit 240.

Title: Communication equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/32
Filed: 1986-10-21
Abstract: PURPOSE:To prevent the deterioration of a received picture due to the influence of a charging pulse by releasing once a circuit when a transmission from a caller side to a callee side is requested, and executing an ordinary transmission after making the facsimile equipment of the callee side call automatically. CONSTITUTION:A control circuit 35 controls the facsimile equipment A which originates a call at first, and the facsimile equipment B which performs the call at the time that an information is actually transmitted. Namely, after the facsimile equipment A detects in initial identifying signal from the facsimile equipment B, the facsimile equipment A transmits a transmission instructing signal (to instruct, by a CIG signal, the facsimile equipment B to originate a call automatically after releasing once the circuit). The facsimile equipment B, responding to this, transmits an MCF signal, then the facsimile equipment A transmits a DCN signal after receiving the MCF signal, and releases once the circuit. The facsimile equipment B calls automatically a telephone number designated by the transmission instructing signal, and transmits the information to the facsimile equipment A. Thus, the deterioration of the received picture due to the influence of the charging pulse is reduced.

The Vi(t) is frequency-converted to a complex modulation signal Wi(t) in the base band zone. At this time, the mixer 3a forms a real part signal and the mixer 3b forms an imaginary part signal. At a base band limiter circuit, an amplitude stabilizing processing is performed on a signal C(t), and it is supplied to a complex multiplier 6 as a reproducing carrier WL(t). In such a way, it is possible to always attain synchronization, and to perform the fast acquisition operation.
