Title: Piezoelectric vibrator
Inventor: MINAMI SEIICHI
IPC: G01C19/5642
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To make the piezoelectric vibrator small-sized and to improve the productivity by providing a piezoelectric substrate and electrodes which are provided opposite on the top and bottom surfaces of the piezoelectric substrate, and forming at least >=3 electrodes each on the top and bottom surfaces. SOLUTION: The piezoelectric vibrator is polarized in the direction from the top to the bottom surface of the piezoelectric substrate 1 or in the opposite direction. Either end of the manufactured piezoelectric vibrator is fixed to a pedestal by using an adhesive. A driving voltage is applied to electrodes 2a and 2b of this piezoelectric vibrator, which then vibrates; and the amplitude and phase of the vibration are measured in the form of voltages through electrodes 4a and 4b to control the applied voltage, thereby performing stable vibration control with small temperature dependency. Further, if an angular velocity having its axis along the length of the piezoelectric vibrator is generated, a force is developed by the Colioris principle along the thickness and measured as a voltage through electrode 3a and 3b, so that the angular velocity can be detected from the measured value.

Title: Frequency modulation system for broad band pll synthesizer
Inventor: SAI KENJI
IPC: H03L7/107
Filed: 1988-05-10
Abstract: PURPOSE:To make the frequency shift constant independently of a modulation signal frequency and a carrier output frequency by using an equalizing section including a gain adjustment circuit and an equalizer so as to process the modulation signal. CONSTITUTION:A PLL circuit consists of a loop filter 4 having a prescribed low pass characteristic, a VCO 5 whose gain is Kv, and a 2nd frequency divider 6 whose frequency division number is 1/N frequency-dividing the oscillated frequency from the VCO 5 and feeding the result to a phase comparator 3 and is provided with a 1st equalizing section 9 and a 1st adder 10 to add a modulation signal while processing it. The transfer function G(s) of the 1st equalizing section 9 is expressed as G(s)=A.G1(s)+B.G2(s), where A=alpha/Kv, B=alpha/N, G1(s)=1/F(s), G2(s)=1/s.tau, F(s) is a transfer function of the loop filter 4 and (s) is the operator. In this case, the coefficient A is controlled inversely proportional to the gain Kv to maintain the relation of A.Kv=alpha (constant) and the coefficient B is controlled inversely proportional to the frequency division N to maintain the relation of B.N=alpha (constant). Thus, even if the carrier output frequency is varied, the frequency shift DELTAomega0(s) is kept constant.

Title: Sheet wind-up device
Inventor: KATAOKA AKIRA
IPC: B65H18/10
Filed: 1985-05-28
Abstract: PURPOSE:To prevent a core from being bent, and to eliminate the generation of longitudinal creases in a sheet due to the tension of the sheet, by providing a sheet roller which rotates while supporting the outer surface of roll of the sheet wound around the core, overcoming a bending load which is exerted to the core by the tension of the sheet to be wound up onto the core. CONSTITUTION:A core support roller 10 which is supported at both ends thereof by the front end sections of right and left support arms 6, swings in association with the growth of a sheet roll Sr. When the sheet roll Sr is shifted into a position Sr' along the locus A due to its growth, the support roller 10 is shifted into a position 10' along a locus B to bear a bending load (f) without hindering the growth of the sheet roll Sr. Since it is only during the initial stage of wind-up at which the wound-up diameter of the sheet rolls is thin, that there is a risk of bending the sheet roll Sr by the load (f) and since the bending resistance of the sheet roll Sr increases when the diameter of the sheet rolls Sr comes to be large, and the support roller 10 becomes unnecessary at that time, and therefore, retracts into a position 10'' as indicated by a chain line, at one end of the locus B. With this arrangement, it is possible to prevent the core from being bent, and to completely eliminate the side slip or edged of the sheet due to the bending and the generation of creases in the sheet due to that.
