Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent the influence to an oscillation frequency by stress due to difference in the thermal expansion rates of a crystal vibrator piece and a package by permitting a straight line to be one of the first straight line making a positive specified angle with an X-axis on the XZ' surface of crystal in an AT cut crystal vibrator piece or the second one making a negative specified angle with it and arranging two fixing parts on the same line. SOLUTION: The X-axis direction of a crystal is adopted in a rectangular short side and the Z-axis direction of the crystal is adopted in a long side in the AT cut crystal vibrator piece 20. Not only the end parts of a pair of front and rear conductive electrodes 16 are positioned on the first and the second straight lines obtained by rotating the X-axis by ±60 deg. but also a segment connecting the end parts of the pair of conductive electrodes 16 is set to be the diagonal line of the rectangular AT cut crystal vibrator piece 20.

Title: Am/fm receiver
Inventor: ASHIDA HIROYUKI
IPC: H04B1/16
Filed: 1987-09-30
Abstract: PURPOSE:To demodulate an audio signal with small distortion factor and less noise by applying synchronizing detection based on a signal being the result of AM audio signal subject to PLL. CONSTITUTION:AM/FM changeover switches 6, 15, 16 are switched to the position of AM and in the AM reception state, then a 456kHz signal is inputted from a flip-flop 13a of a divider 13 and a signal of intermediate frequency 455kHz from an AMIF2c is subject to synchronizing detection by using the 456kHz signal as the synchronizing signal. Moreover, the PLL is applied corresponding to the signal of 455kHz in the phase detection circuit 9 and a pilot signal detection circuit 8 generates an output signal at a level corresponding to the 455kHz signal. Since the audio signal of the AM is subject to synchronizing detection based on the signal subject to PLL processing, the audio signal with small distortion rate and less noise is demodulated from the envelope detection wave.

Title: Polarization controller
Inventor: YAMAMOTO TAKESHI
IPC: G02F1/01
Filed: 1993-09-07
Abstract: PURPOSE:To widen designability regarding parameters of liquid crystal and improve the designability of the polarization controller by stacking plural ferroelectric liquid crystal sheets which have the same tilt angle and rubbing direction one over another so that their liquid crystal axes are put in order. CONSTITUTION:The ferroelectric liquid crystal sheets 11-1n which have the same tilt angle DELTAtheta and rubbing direction R are put one over another having the liquid crystal axes put in order so that the total retardation of those liquid crystal sheets 11-1n is a desired value. Then when conversion between P polarized light and S polarized polarization is performed by using the polarization controller using the ferroelectric liquid crystal, the rubbing direction R of the liquid crystal should be + or -22.5 deg., the tilt angle DELTAtheta should be 22.5 deg., and the retardation should be (2n+1)/2 as large as in-use wavelength lambda2 (n: integer). Further, while the designability of parameters of the liquid crystal is widened, their conditions are actualized by putting those liquid crystal sheets one over another. Further, the desired retardation required for the polarization control is obtained by putting the liquid crystal axes of the liquid crystal sheets 11-1n in order.

Title: Optical communication system
Inventor: FUKUDA AKIRA
IPC: H04B17/00
Filed: 1985-11-01
Abstract: PURPOSE:To transmit a main transmission signal and a supervisory ordering signal through one optical fiber by superimposing a low frequency supervisory ordering signal on a binary digital pulse main transmission signal as one side amplitude modulation to send independently the digital pulse signal and the supervisory ordering signal. CONSTITUTION:A waveform of a binary digital optical signal as a main transmission signal shown in figure (c) shows that the signal is sent by making the pulse width different. The waveform of a low frequency used as the supervisory signal in figure (b) can be considered to be an optical signal after electrooptic conversion. The main transmission signal in the figure (c) and the supervisory signal in the figure (b) are superimposed to form a composite signal, and in figure (a) indicating the waveform being the result of supervision, the digital signal being the main transmission signal is shown as a major signal and it is the waveform modulated vertically by the low frequency signal. The upper/lower envelopes of the composite waveform are assymetrical, but it is possible to detect the upper or lower envelope by a peak detection type detector, and when the binary digital signal being the main signal is not modulated and only the low frequency signal exists, the low frequency signal is detected by the peak detection type detector similarly. The effect of the presence of the superimposition of the low frequency signal is almost evaded.
