Title: Optical equalizer
IPC: G02B6/122
Filed: 1992-03-30
Abstract: PURPOSE:To cancel the dispersion of an optical fiber without converting a light signal into an electric signal by arranging a specific number of multiplied waveguides at equal intervals from the coupling part of output-side waveguides. CONSTITUTION:Two multiplied waveguides each, i.e., 6-9 are arranged at equal intervals and at the same distance from the coupling part of the two output-side waveguides 3 and 4 of a directional coupler 5. Then this optical equalizer consists of input-side optical waveguides 1 and 2, the output-side optical waveguides 3 and 4, a 3dB directional coupler 5 with a 50% coupling rate, 1st multiplied reflection waveguides 6 and 7, 2nd multiplied reflection waveguides 8 and 9, and constant-length optical waveguides 10 and 11 sandwiched between the multiplied reflection waveguides 6 and 8, and 7 and 9. Consequently, the multiple reflection of light is caused in the optical waveguide where the two couples of multiplied reflection waveguides 6-9 or a dielectric multi-layered film is arranged, and optional propagation delay characteristics are obtained by properly selecting the intervals of the multiplied reflection waveguides 6-9 or the dielectric multi-layered film, i.e., the reflection factor and the time required for light to go and return through an optical waveguide whose length is 1.

Title: Hybrid integrated circuit
Inventor: OOHATA NORIYUKI
IPC: H01L23/32
Filed: 1983-04-27
Abstract: PURPOSE:To eliminate the strike-out of a case, to decrease processes while preventing the slip-off of a substrate and to improve safety by forming structure in which the substrate is held by the case regardless of the positions of leads for the substrate. CONSTITUTION:One of an integrated circuit substrate 1 is inserted between one pawl section 4 in a case and a support base 5, and the other is pushed lightly with fingers, inserted by utilizing the deflection of a resin constituting the substrate 1 and fixed. Since the force of hold-down of the substrate only by the pawl sections 4 in the case and the support bases 5 after mounting the integrated circuit substrate 1 is weak, an auxiliary support base such as four auxiliary support bases 3a, 3b, 3c, 3d are mounted, the shaking or inclination of the integrated circuit substrate 1 is prevented, and safety is improved.

Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To improve repeated usability of a core by setting an inner tube inserted in an outer tube, to a winding shaft, and making the outer tube and inner tube attachable to and detachable from the winding shaft by the enlargement and contraction of the winding shaft. SOLUTION: This core 10 is set to a winding shaft 21 of a winding device 20 to wind a web. The winding shaft 21 is provided, in a plurality of circumferential position, with lugs 22 protruded and recessed from the outer peripheral surface by a pressurized fluid or the like, and the chucking outer diameter of the core 10 by the winding shaft 21 can be enlarged and contracted by the lugs 22.

Title: Control of pulse width modulation for ac/dc converter
Inventor: WAKAO MASAAKI
IPC: H02M7/155
Filed: 1989-03-27
Abstract: PURPOSE:To prevent the generation of an overcurrent and permit the permit protection of an AC/DC converting device by a method wherein the AC-side voltage of the AC/DC converting device is controlled so as to follow the instantaneous value of the induced voltage of a main transformer, which is changed in accordance with the generation of flux deviation. CONSTITUTION:A main transformer 2A is provided with a detection winding 100 at a position not interferred by the affection of flux leakage and the like, due to other main winding current. The output of the detection circuit 101 of the detection winding 100 is applied on the input side of a BPF 22, extracting only the fundamental wave of a voltage. The detection winding 100 and the detection circuit 101 detect an induced voltage, fluctuated in accordance with the primary voltage of the main transformer 2A. The AC side output voltage of an AC/DC converter 3 is controlled so as to follow the induced voltage. Accordingly, when the flux of the main transformer 2A is deviated and the secondary counter induced voltage is reduced, the AC side output voltage of the AC/DC converting device 3 may be coped with it immediately whereby an overcurrent due to a difference between both voltages will never be generated.

Title: Data decoding method
Inventor: HOONGUUDAA RIN
IPC: H03M13/47
Filed: 1995-03-08
Abstract: PURPOSE: To actualize the decoding of a high-rate trellis code with good area efficiency. CONSTITUTION: Code states are assigned to respective process elements 135. Then the calculation of new path metrics in a process element is scheduled by using calculated path metrics and branch metrics which are different by encoded data, Further, access to the calculated path metrics from respective process elements 135 is scheduled so that some of the calculated path metrics are accessed in order. A survival sequence of the path metrics calculated according to the alcove-mentioned scheduling is used to evaluate data before encoding. Further, the path metrics are rearrayed after calculation so as to facilitate access in subsequent calculation. This method divides data points corresponding to the path metrics into several slots and replaces the data points so that data points occupying incorrect slot positions to other slot positions.

Title: Loudspeaker
Inventor: SHIMADA KOUSHIN
IPC: H04R7/12
Filed: 1981-05-18
Abstract: PURPOSE:To constitute so that no air in an enclosed space leaks even in case of vibration fatigue, by constituting an elastic substance forming a part of the enclosed space, of rubber, in a loudspeaker which uses the enclosed space as a mechanical filter. CONSTITUTION:When a bobbin 7 vibrates slowly, this vibration is transmitted to a diaphragm 2 through an enclosed space, but when the bobbin 7 vibrates quickly, expansion and contraction of the enclosed space comes not to follow a movement of the bobbin 7 and vibration of the bobbin 7 comes not to be transmitted to the diaphragm 2, therefore, the function being equivalent to a low-pass filter is realized. In this case, if rubber is used as an elastic substance 4, no air leaks even in case of vibration fatigue unless the elastic substance 4 itself is detached from a sub-diaphragm 5 or a coupler ring 14, and prescribed gas elasticity is always obtained. Also, the elastic breakdown can be prevented by laminating woven fabric on the reverse side of the elastic substance 4.
