Title: Fiber type optical equalizer
Inventor: TAKEUCHI YOSHIAKI
IPC: H04B10/2525
Filed: 1992-09-16
Abstract: PURPOSE:To eliminate the dependence upon polarization of characteristics, to remove restrictions from the number of stages of circuits, and to obtain excellent connectability to optical fibers by forming an optical coupling part by stretching of a dual core fiber to constitute a multistage Mach-Zehnder filter. CONSTITUTION:This fiber type optical equalizer is made of the dual core fiber where two cores different in propagation coefficients are formed in the sane clad with such distance between them that they are not optically coupled to each other. That is, plural parts in the lengthwise direction of the dual core fiber are stretched to produce 3dB couplers 4 and a 100% coupling coupler 5 as optical coupling parts between two cores, thus the optical equalizer is constituted of the multistage Mach-Zehnder filter. An optical signal is inputted from the first core placed in the center of the clad and is moved to the second core because of the existence of the 100% coupling coupler 5 in the input end and is inputted to the equalizer. The difference between propagation coefficients of two cores is used for the delay time difference, and this time difference is controlled by the length of the dual core fiber between couplers.

Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To always set an optical axis vertical to an information recording surface following the warping of an optical disk by providing a slide bearing mechanism for permitting a movable body to be slid in an axial direction, rotated around an axis and rotated in a direction nearly orthogonal to the axial direction. SOLUTION: A slide shaft 6 is fixed in a base 12 by a pressing-in method or the like. The movable body and slide shaft of an optical pickup 2 are received by a slide bearing part 13. A surface for regulating a bearing hole is formed as a tapered part 14 to have a tapered angle more than a rotary angle to be controlled. Since its thickness is almost equal to that of a clearance, the slide bearing part 13 had no substantial rigidity of a rotating direction and is positioned by providing a control system of a rotating direction.

Inventor: NISHIKAWA KOZO
IPC: G01C19/72
Filed: 1989-09-21
Abstract: PURPOSE:To easily specify the rotational direction of the optical fiber gyro in a short time by comparing waveform data based upon the output signal of a synchronous signal generation part among sampled data obtained by an A/D conversion part with basic waveform data. CONSTITUTION:The A/D conversion part 9 samples the output signal of a signal generation part A. The synchronous signal generation part 12 outputs a signal in synchronism with the modulated signal of a phase modulator 6.

Title: Composite longitudinal vibration mechanical filter
Inventor: TAKEUCHI YOSHIHIKO
IPC: H03H9/46
Filed: 1989-09-21
Abstract: PURPOSE:To improve the passing characteristic by providing a vibration absorbing body support arranged between both ends of a support member and a vibrating absorption body fixed to the said vibration absorbing body support so as to reduce undesired spurious response at the outside of the pass band. CONSTITUTION:An input side longitudinal vibration sound piece 32 vibrates longitudinally in directions of arrows Mi and Mo and simultaneously vibrates in the axial direction of a support member 40. This vibration propagates through the support member 40 and is absorbed by a vibration absorbing body 42a fixed to a vibration absorbing body support 42. The vibration not absorbed therein propagates an outer frame member 50 and is absorbed by a vibration absorbing body 43a integrated with a vibration absorbing body support 43 to which the end of a support member 49 is fixed. Thus, an undesired vibration wave transferred to an output side longitudinal vibration sound piece 34 is effectively absorbed by vibration absorbing bodies 42a, 43a fixed to the vibration absorbing body supports 42, 43 to reduce the undesired spurious response outside of the band.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To properly process a number display signal, in the case of connecting a telephone set having provision or no provision for a number display service to a telephone communication unit such as a multi-function telephone set as an externally mounted telephone set. SOLUTION: An operation panel 13 designates whether an externally mounted telephone set 2 connected to an external terminal 2a of a multifunction telephone set 1 is provided with a caller telephone number display function. A call signal is received in succession to a caller telephone number notice signal from a telephone line network 20. When the externally mounted telephone set 2 is provided with a caller telephone number display function, the externally mounted telephone set 2 conducts reply processing with respect to the caller telephone number notice signal, and the multi-function telephone set 1 conducts no reply processing. Thus, a nonconformity, where the reply processing is conducted twice and the resulting signal is sent to the telephone line network 20 can be avoided.  When the externally mounted telephone set 2 is not provided with the caller telephone number display function, only the call signal is sent to the externally mounted telephone set 2 and the caller telephone number display is made using multifunction telephone set 1.

Abstract: PROBLEM TO BE SOLVED: To improve a transmitting capacity and durability of a metal belt by restricting a contact ratio obtained by dividing a right and left direction width of a saddle surface by a right and left direction width of a metal ring to an upper limit and lower limit. SOLUTION: A right and left direction width Ws of a saddle surface 39 of a metal element 32 is set to be not more than a right and left direction width Wr of a metal ring aggregated body 31, and a right and left direction inner end of the metal ring aggregated body 31 is overhung to a neck part 38 side from the right and left direction inner end of the saddle surface 39. A value obtained by dividing a right and left direction width Ws of the saddle surface 39 by a right and left direction width Wr of the metal ring aggregated body 31 is defined as a contact ratio (Ws/Wr<=100%).  In this time, an upper limit within a suitable contact ratio is such a contact ratio that a transmitting capacity change rate is diverted from a negative value to a positive value, a lower limit is a contact ratio capable of realizing taking a misalignment into consideration, and a reliable contact ratio is set to a range between the upper limit and the lower limit. It is thus possible to reduce the transmitting capacity, and it is also possible to prevent reduction of durability.
