Abstract: PURPOSE:To determine true detected data to realize accurate reading by canceling the dislocation of light quantity distribution by using plural position detecting elements to eliminate the dislocation. CONSTITUTION:In a reflection type optical detecting sensor 11 for reading a reflected beam 16 from a light source LED 12 radiated to the surface of a paper sheet 15 by a position detecting element to read the surface of the paper sheet 15, plural position detecting elements 13 and 14 for receiving the reflected beam 16 from the paper sheet 15 are arranged in a light-receiving symmetric position with the light sensor 12 as a center. Then light-receiving detecting data received by the plural position detecting elements 13 and 14 are averaged to determine the surface data of the paper sheet. Consequently in a light-receiving detected data obtained from a pair of position detecting elements 13 and 14 with the light source 12 as a center, opposite reflected variation values of one side and the other side can be canceled to obtain only true detected data. As a result, highly reliable and stable accurate detection measuring can be performed regardless of that even a pattern is printed or a wrinkle is formed on the surface of the paper sheet 15.

Filed: 1990-11-20
Abstract: PURPOSE:To transmit a non signal state to a transmission line without use of an expensive component by switching a signal from a wiring to a specific signal when the wiring is in non signal state and generating a non-signal state to the wiring when the received optical signal is the specific signal. CONSTITUTION:When a cable 3 reaches a non-signal state and an output signal 21 of a retiming unit 5 is not changed, a detection unit 7 detects it. Then a signal 22 is used to inform the state change to a switch 8 and a low frequency generating unit 6 and a low frequency signal resulting from changing forcibly the signal 21 at a prescribed period, that is, a silence signal 23 is started to be outputted. The switch 8 selects the input signal 24 to the optical transmission unit 9 from the signal 21 to the signal 23 and the unit 9 transits from the data signal transmission state into the silence signal transmission state. When an output signal 25 of the optical reception unit 11 changes to the silence signal, the unit 12 of the optical reception section 2 detects it, an output signal 26 changes and the switch 13 is opened. Thus, the input signal 27 of the retiming unit 14 reaches the non-signal state.

Title: Dynamic damper structure of propeller shaft
Inventor: KUDO JINSEI
IPC: F16C3/02
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a compact dynamic damper structure of a propeller shaft, capable of inhibiting the vibrational noise caused by the natural frequency of an engine mounting bracket. SOLUTION: This dynamic damper 10A is formed by an annular rubber body 58 and a front propeller shaft 6A by forming a cut part 51 on a first engine side bracket part 48, and mounting a ball bearing 63 on the cut 51 via the annular rubber body 58. By forming the front propeller shaft 6A with a mass body, the increase of the mass can be prevented in comparison with a conventional technique, where the mass body is independently mounted. As the annular rubber body 58 or the like is accommodated in the cut 51, the constraint on an installation space can be reduced in comparison with a conventional technique, where a dynamic damper is externally mounted on an engine mount bracket, which makes the structure small in size.

Title: Optical transmission system for bipolar signal
Inventor: TANAKA NOBUYUKI
IPC: H04B10/2507
Filed: 1988-12-14
Abstract: PURPOSE:To omit a bipolar/unipolar conversion circuit by separating a bipolar signal into the positive and negative pole side signals at the transmission side and converting them into the positive and negative pole side optical signals having different wavelengths and transmitting both optical signals after synthesizing them into an optical multiple signal. CONSTITUTION:At the transmission side a bipolar signal A is outputted to an electric signal separating circuit 1 and separated into a positive pole side signal B and a negative pole side signal C. The signal B is converted into a positive side optical signal D having a prescribed wavelength via a light emitting part 2a. At the same time, the signal C is converted into a negative pole side optical signal E having a prescribed wavelength different from the signal D via a light emitting part 2b. Then both signals D and E having different wavelengths are synthesized by an optical synthesizing part 3 and turned into an optical multiplex signal F. This signal F is sent to an optical fiber 4 serving as an optical transmission line. Thus it is possible to transmit the signal A without converting this into a unipolar signal.
