Title: Waveguide type phase shifter
Inventor: YONEKURA MASAMICHI
IPC: H01P1/195
Filed: 1980-09-30
Abstract: PURPOSE:To prevent a decrease in the extent of phase shifting during high mean electric power operaion by reducing mechanical strain, by dividing the ferrimagnetic body of a waveguide type phase shifter. CONSTITUTION:A ferrimagnetic body 2 is arranged in contact with the upper and lower walls of a aveguide 1, and in the center of the magnetic body 2, a hole 3 is made to run a conductor 4 through it. Further, the magnetic body 2 is divided at prescribed position 5 to adequate length. Since heat generated by the magnetic body 2 is conducted to the waveguide 1 through the contact surface with the waveguide 1, the magnetic body 2 has temperature distribution high at the center part and low at the upper and lower surfaces, and at the center part, axial mechanical strain is generated, but the magnetic body is divided to the adequate length, thereby preventing the reduction of residual magnetization due to the mechanical strain. In addition, dielectrics, etc., softer than the magnetic body 2 are introduced into the division parts 5 of the magnetic body 2 to further improve strain accumulation preventing effect.

Title: Terminal structure of optical connector ferrule
Inventor: MORIYA KAORU
IPC: G02B6/36
Filed: 1987-05-29
Abstract: PURPOSE:To eliminate the need for high-accuracy polishing of the terminals of optical fibers and to satisfactorily join said terminals without mis-alignment by adopting the constitution consisting in packing a curable fluid body around the terminals of the optical fibers projecting from the end faces of ferrules and polishing the end faces approximately perpendicularly to the axial center after curing. CONSTITUTION:The exposed part of the optical fiber 6 from which a covering material 8 of an optical fiber core 7 is removed is inserted into an insertion port 10a of the ferrule 10 through a hole part 4a of a supporting member and the curable fluid body 12 is packed into a tapered part 10c. The terminal 6a is cut after the curing and the end face 10b is polished. The end faces of these two ferrules 10 are satisfactorily tightly adhered by the pressing force of the ferrules even if the high-accuracy polishing of the end faces such as spherical polishing is not executed if the end faces of the ferrules are joined and are optically coupled to each other. Since the outside circumferences of the ferrules can be exactly positioned, the connection loss is decreased and the end faces are satisfactorily connected without the mis-alignment of the optical axes.

Title: Electromagnetic flowmeter
Inventor: SOMEYAMA TAKAO
IPC: G01F1/60
Filed: 1981-08-31
Abstract: PURPOSE:To facilitate the winding and assembling of coils and to make the device inexpensive, by providing the exciting coils having the windings from one turn to several turns, and providing a switching circuit which is driven by a frequency that is a fraction of an integer of a commercial power source frequency between an exciting power source and the exciting coils. CONSTITUTION:The exciting coils 15a and 15b having the windings of the turn arc arranged around a fluid pipe 17. When a switch 12 is turned ON and OFF by the switching circuit at the frequency that is a fraction of the integer of the commercial power source frequency, a constant current from a constant current source 11 flows through a primary side 14a of a current transformer 14 as a rectangular wave current. The current is largely amplified by the current transfomer 14 and flows into the exciting coils 15a and 15b, and the magnetic field is generated in the fluid pipe 17. When the electromagnetic fluid flows through said magnetic field, a voltage (e) is generated across electrode 18a and 18b, and the flow rate is generated. Since the constitution of the exciting coils are simplified, the winding and the assembling of the coil are simplified. Since commercially available products can be used for the current transformer 14, the present device can be made at low cost.

IPC: H03M13/23
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a receiver by which accuracy of maximum likelihood decoding (Viterbi decoding) is improved and a BER(bit error rate) is reduced even when the state of the line is deteriorated. SOLUTION: A discrimination control section 120 uses a square root mean E (k) of an error signal (e) in training to discriminate a convergence state of a modem. In this case, a discrimination decoding device 114 revises a trelis length used for decoding based on a discrimination result from the discrimination control section 120. That is, a modem at a receiver side compares the square root mean E (k) of the error signals in training with a prescribed threshold level set in advance and changes the trelis length used for maximum likelihood decoding (Viterbi decoding) depending on the result of comparison.
