IPC: G02B6/122
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To make obtainable a variable wavelength mechanism by external stress by integrating a variable wavelength mechanism with a diffraction grating type optical filter using a polymer material. SOLUTION: The diffraction grating type optical filter comprises a core 3' having a diffraction grating 4 formed thereon, which is nipped by clads 2, 5. As the filter material, fluorinated polyimide is used. An air-gap 9 is inserted from one side between the lower clad 2 and a substrate to lay the lower clad 2 in a cantilever-shaped floating state, so that an element is longitudinally expansible and contractible. A super-magnetostrictive alloy plating film 8 is integrally laminated on the upper clad 5 to function as a wavelength variable mechanism. An external magnetic field is applied to the super-magnetostrictive plating film 8 to impart the change in length by the magnetostrictive effect to the diffraction grating type optical filter, changing the period of the diffraction grating 4 of the core 3', thereby, Bragg wavelength can be changed.

Title: Charge/discharge control circuit
Inventor: TERATANI SHIGEKI
IPC: G06F1/28
Filed: 1989-08-03
Abstract: PURPOSE:To eliminate fine adjustment and error correction for ambient temperature and to grasp the battery capacity accurately by producing a charge clock signal and a discharge clock signal and monitoring the battery capacity according to the count of a counter. CONSTITUTION:A detecting circuit 12 monitors the count of an up/down counter 9, and produces a charge start signal when the count of the counter 9 drops below a predetermined value. When the count of the up/down counter 9 is higher than the predetermined value, a battery 4 is charged. Upon occurrence of power interruption, the battery 4 is connected with a load circuit 2 and the load is driven. A control circuit 13 reads out the count of the counter 9 and determines the residual capacity of the battery 4. When the battery 4 is discharged and the battery voltage drops, voltage supply to the load circuit 2 is interrupted. By such arrangement, fine adjustment of the battery and correction for temperature variation are not required and the battery capacity can be grasped accurately.

Title: Extended bus system
Inventor: MICHINO MASAMI
IPC: G06F12/02
Filed: 1987-08-17
Abstract: PURPOSE:To avoid increase of the number of signal lines of an extended bus by securing the shared use between an extended bus where an address is kept fixed during an access and another extended bus where an address is switched to another address to perform the next access during an access. CONSTITUTION:An address decoding circuit 1 allocates a prescribed address area to an extended bus where an address is kept fixed during an access. An address enable signal latch circuit 2 holds the output of the circuit 1 during an access. An address latch circuit 3 holds an address during an access given to an address area decoded by the circuit 1. An address latch control circuit 4 produces the address holding timing of the circuit 3. Then plural selection circuits 51-53 which switch the output of the circuit 2 and the bus access permission signal put on an address bus and apply them to the extended slots 61-63 respectively. Thus the shared use is possible between the extended bus where an address is kept fixed during an access and another extended bus where an address is switched to another address to perform the next access during an access. As a result, the number of signal lines is never increased for an extended bus.

Title: Lead wire for oil-immersed induction apparatus
Inventor: HASHIMOTO MITSUMASA
IPC: H01F27/04
Filed: 1986-09-01
Abstract: PURPOSE:To reduce the size of an oil-imersed induction apparatus by forming a mixed material of a low dielectric constant plastic and pulp for use in a coating insulator, a wavy spacer and an insulating barrier by alternately disposing a mixed layer of the plastic and the pulp and a pulp laminating layer, and forming the pulp laminating layer on both side surfaces. CONSTITUTION:A multilayer insulating barrier type lead wire is formed by using a coating insulator 13 at a central conductor 12, concentrically disposing a plurality of insulating barriers 15 through wavy spacers 14 on the outer periphery of the insulator, and providing a shielding electrode 16 on the outermost layer. The insulator 13 of the conductor 12 uses a mixed material of a low dielectric constant plastic and pulp, and the mixed material has a mixed layer 17 of the plastic and the pulp at its inner layer and pulp laminating layers 18 disposed on both side surfaces of the layer 17. When the layers 18 are used in contact with insulating oil, they have effects of suppressing the separation of the plastic fiber and preventing the surface from becoming fuzzy. They can also alleviate the concentration of an electric field of an oil gap due to the difference of the dielectric constants of the mixed material and insulting oil, thereby largely improving its dielectric breakdown strength. Thus, it can reduce the size and weight of an oil-filled induction apparatus.
