Title: D/a converter
Inventor: NOMA TOSHIHIRO
IPC: H03M1/80
Filed: 1990-03-06
Abstract: PURPOSE:To switch resolution without changing the conversion accuracy of a D/A converter by changing the amplification factor of an operational amplifier to output each analog signal to be outputted from each analog array, to which a digital signal is impressed, while synthesizing and amplifying the analog signals. CONSTITUTION:When an analog voltage is precisely controlled, a switch Sf is changed over from Rf of Rf1 by a control signal P11. Thus, in respect to inputs I0, I1 and I2, a range for the analog output of D/A conversion can be set to Rf/Rf. Therefore, since the narrowed-down range is resolved by the same resolution, the D/A conversion is executed with the high resolution. Namely, by changing a resistance ratio between the synthesized resistance value of resistance arrays R0, R1 and R2 and the feedback resistance of the operational amplifier, the width of the output voltage can be changed and the resolution of the D/A conversion can be switched.

Title: Pinch roller
Inventor: MATSUOKA KAORU
IPC: G11B15/29
Filed: 1984-03-22
Abstract: PURPOSE:To exclude generation of wow and flutter at a tape constant speed running due to variation of rubber hardness of a weld part formed at forming by forming the weld part formed on a cylindrical rubber elastic layer not in parallel with the capstan shaft. CONSTITUTION:Plural gates are formed as plural gates 9 not in parallel with the axial direction of a pinch roller 8, and when the pinch roller 8 formed by a metallic die having the gates 9 is pressed in parallel with a capstan shaft 5, the weld part 10 is formed so that the weld part 10 of the pinch roller 8 is not in parallel with the capstan shaft 5. Since the change in the cross sectional area of the pressing part is small, the change in the average speed in the circumferential direction of the pinch roller at the pressing part is small, and then the tape speed fluctuation is made small in running a tape at a constant speed and wow and flutter is very small in comparison with the tape running by using a conventional pinch roller.

Abstract: PURPOSE:To decrease the burden of a boarding passenger when a boarding card is automatically examined by reading boarding card data written on the boarding card by a noncontact transmission system, and when the data do not coincide with the reference data, notifying noncoincidence to the boarding passenger. CONSTITUTION:When a boarding passenger 15 having a boarding card 12 approaches a boarding card data read means 12, the means 12 reads boarding card data DATA stored into the boarding card 12 beforehand, a deciding means 13A compares the data DATA with the reference inspection data concerning a boarding gate 16, and a notifying means 13F notifys a decision result to the boarding passenger 15. Consequently specific work is not required from the boarding passenger 15. Thus when the boarding card is automatically examined, the burden of the boarding passenger can be decreased.

Title: Carrier recovery circuit
Inventor: SETA MITSURU
IPC: H04L27/227
Filed: 1986-03-13
Abstract: PURPOSE:To stabilize phase control by providing a narrow band filter having prescribed phase characteristics between an inverse modulation circuit and a phase detector to attain the phase control resistant to noise with high sensitivity. CONSTITUTION:The narrow band filter 5' is provided between an output of the inverse modulation circuit 1' and one input of a phase detector 4. Thus, the phase theta with respect to a frequency deviation DELTAf given to the input is larger than the phase theta with respect to the frequency deviation DELTAf given from the narrow band filter 2 to the other input, the sensitivity is improved clearly by a significant quantity more than conventional phase difference detection using the filter 2 only and the phase noise in the input signal to the detector 4 is reduced at the same time. Through the high sensitive phase difference detection, the transition to the inverse phase control caused in using a phase compensation filter as the filter 2 is prevented and the control contributes to the stabilized phase control. Further, an integration device 6' reduces phase noise components.
