Title: Phase detecting method
Inventor: YAGI TOSHIYUKI
IPC: H03D3/22
Filed: 1983-07-27
Abstract: PURPOSE:To eliminate a measuring error based especially on a phase error by inputting an identical input signal to two phase detectors, applying phase detection to the signal with reference signals apart by nearly 90 deg. from each other and also conducting the phase detection while the phase of the reference signals is shifted sequentially by a prescribed amount. CONSTITUTION:This method is a method that plural measurements are conducted by shifting sequentially by a certain angle the phase of the reference signals applied to each one input of the two phase detectors and the measured values are averaged. The reference signals E4, E5 from a phase signal generator 13 include a phase error epsilon and a difference alpha of a conversion efficiency of the phase detectors 11, 12. An output signal of the phase detectors 11, 12 to the E3, E5 is obtained by shifting sequentially the phase by theta=90 deg.. The vector voltage ratio of unknown signals E1, E2 is expressed by an equation using outputs XA, YA and XB, YB of the detectors 11, 12 with the unknown signals E1, E2 inputted. Further, outputs with theta=0 deg., 90 deg., 180 deg. and 270 deg. are obtained and averaged so as to obtain ¦E2/E1¦. Thus, the errors alpha and epsilon are compressed. Since the two phase detectors are used in this case, the measuring time is decreased.

IPC: B62J33/00
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To prevent breaking of a heater wire and deformation of a lead wire due to a pressure at molding time, by forming a ring corresponding to the cross sectional external shape of a grip base out of the specific number of the lead wires, and fitting this ring to the outer periphery of the grip base. SOLUTION: First a heater wire is wound in zigzag shape to a heater fixing rib 4 in a grip base 1. Next a lead wire 3 is connected to the heater wire 2 by a connector 7. The two lead wires 3 are arranged to be drawn out from one end of the grip base 1, after these two lead wires 3 are spread in an annular shape on the halfway, this annular shape formed lead wire 3 is fitted to the outer periphery of the grip base 1.

Abstract: PURPOSE:To easily detach a handset by forming the tip part of a movable engagement pawl in such a way that an outside inclination surface and an inside inclination surface become acute with respect to the rising and setting direction of the movable engagement pawl. CONSTITUTION:When a receiving part 13 in the handset 11 is detached from a recessed part 20 in a handset pedestal 12, force for detaching the receiving part 13 in the handset 11 operates on the tip inclination surface 33 of the movable engagement pawl 23 from the receiving part 13. With the force, the engagement pawl 23 is shifted to a setting direction, whereby partial force is generated. Consequently, the engagement pawl 23 is set in the pedestal 12 against the force of a spring 29, whereby the pawl 23 is detached from the engagement hole 16 of the handset 11. By operating force for detaching the handset 11 with respect to the outside inclination surface 32 and the inside inclination surface 33, the engagement pawl 23 can be set into the inner direction of the pedestal 12 against spring force. Consequently, the handset 11 can easily be detached only with adding force for detaching the handset 11.

Abstract: PROBLEM TO BE SOLVED: To obtain a block noise eliminating method by which the distortion of a digital image is reduced and the sharpness of a digital image is maintained by limiting the application range of correction of a digital image to the distorted part and by which the memory capacity can be reduced by limiting referred data to only adjacent blocks. SOLUTION: The block positions of a block image after discrete cosine transform and of a block image adjacent to the above block image are detected, a DC capture 30 captures their DC coefficients and a new DC coefficient of the block image is obtained by a DC generator 40 on the basis of the DC coefficients. In the case of obtaining this new DC coefficient, the DC generator 40 obtains a parameter from the outside.  Discrete cosine transform is applied twice to one block by using each of the new DC coefficients generated by the DC generator 40 and the original DC coefficient, a block memory 50 stores the result of the 1st discrete cosine transform using the original DC coefficient, and a selector 60 selects the result of the 1st or 2nd discrete cosine transform in matching with the output of the result of the 2nd discrete cosine transform using the new DC coefficient to the same block and provides the output of data 80.

Abstract: PURPOSE:To sharpen the outline of a picture by impressing a rectangular wave signal being formed to a signal with a rising period and a falling period of electric potential at a leading edge and a trailing edge of the signal are lengthened in a wave form shaping circuit between bar electrodes. CONSTITUTION:A trapezoidal wave generating circuit 12 is provided, which generats a trapezoidal wave with an input of a rectangular wave signal of a generator 11 generating the rectangular signal corresponding to a character or the like.
