Patent JP-H0575448-A (JP)
Title: Dpll device
Inventor: SATOMURA SEIICHIRO
IPC: H03L7/06
Filed: 1991-09-13
Abstract: PURPOSE:To prevent occurrence of a rapid phase shift by detecting a phase difference with respect to an input signal when a phase difference between output signals of 1st and 2nd reference signal generating means almost reaches a minimum value and selecting and outputting the output signal. CONSTITUTION:A frequency of a signal fL of an oscillator 1a is set smaller than a frequency of an input signal and set larger than a frequency of a signal fH of an oscillator 1b. Then an output signal S4 of a phase coincidence detection circuit 6 rises at a high level when a phase of the signal fH overtakes a phase of the signal fL. Then the phase coincidence detection circuit 6 detects a point of time when a phase difference is least and a phase coincidence signal S4 is outputted to a latch 5. The latch 5 uses the signal to latch an output of a phase comparator circuit 4 at that point of time and a multiplexer 2 uses a latch signal (selection signal) S5 to select and output either of the signals fL, fH. The signal selected by the multiplexer 2 is frequency-divided by a frequency divider 3 and the result is outputted as an output clock S2.

Title: Feeding device for paper sheet and the like
Inventor: NAGASAWA TOMOJI
IPC: B65H1/02
Filed: 1985-11-22
Abstract: PURPOSE:To make it possible to align the bottom edges of paper sheets and the like without doing damage to the paper sheets and to take out one sheet after another by moving a flat-topped position aligning member reciprocally up and down, with the vibration timing arranged in consideration of the falling timing of the sheets and by making such that the falling sheets, once received on a base, is then pushed up with the base. CONSTITUTION:Since the bottom edges of pieces of mail P-1, P-3 and P-5 are contacting a base 2 while pieces of mail P-2 and P-4 are floating, when a shaking means 5 and a position aligning member 22 are shaken, the shaking means 5 takes out the mail P-1, P-3 and P-5 inserted between pins 5a while keeping an upright attitude and transfers them to a takeout means 6. On the other hand, as a fixed roller 27 is rotated clockwise via a belt 26, the position aligning member 22 is raised via an arm 31 linked to the roller 27. As a result, while the mail P-1, P-3 and P-5 are pushed up with the position aligning member 22, the mail is not damaged because the top surface of the position aligning member 22 is flat. After that, the bottom edges of the mail are received with the top surface of the base 2, the mail P-2 and P-4 are entered by their own weights into gaps among the mail P-1, P-2 and P-3 and aligned by repeated operations while being transferred to a takeout means 6. The mail is then transferred one to a transfer means.

Title: Light transmittance measuring apparatus of optical fiber
Inventor: SATO TATSUMI
IPC: G01M11/02
Filed: 1990-09-29
Abstract: PURPOSE:To obtain a measuring apparatus with high utilizing efficiency of light which can measure the true transmittance of an optical fiber by so adapting a condensing lens as to take two positions at the side closer to a light source and at the side closer to an incidence window of a light measuring part on an optical path of a projecting light of a spectroscope. CONSTITUTION:In a sample chamber 2 for measuring an optical fiber, a luminous Fs of a sample sent from a sample chamber C is reflected by a concave mirror M3 towards an incidence window W1 of an integrating sphere I. Similarly, a contact luminous flux Fr is condensed by mirrors M5, M6 to the other incidence window W2 of the integrating sphere I. The mirror M3 is spaced considerably from the integrating sphere I. Therefore, a condensing lens 3 can take two positions A and B on an optical path from the mirror M3 to the incident window W1 of the integrating sphere I. Accordingly, the whole of the luminous flux generated from a spectroscope can be condensed and introduced into the optical fiber and the light output from the optical fiber can be totally guided into a projecting opening of a photodetecting part. Therefore, the luminous flux related to the measurement is made the same between when 100% transmittance is measured and when the sample is measured.
