Title: Optical switch
Inventor: KAWAKAMI GOJI
IPC: G02F1/313
Filed: 1988-11-02
Abstract: PURPOSE:To suppress the optical misalignment when a waveguide light travels straight by constituting the title optical switch so that an equivalent refractive index of a refractive index control area in an intersection part of a waveguide becomes larger than an equivalent refractive index of other intersection part than said area. CONSTITUTION:In an optical switch for allowing two semiconductor optical waveguides 1, 2 to intersect at a prescribed angle 2theta, providing an area 7 in which a refractive index drops by an electrical control on a part in its intersection part 6, and switching an optical path by a total reflection caused by a drop of its refractive index, an equivalent refractive index of the area 7 is made larger than an equivalent refractive index of the intersection part 6 except the area 7. For instance, thickness h3 of a waveguide layer 14 in the refractive index control area 7 is made larger than thickness h2, or a layer 71 whose composition is different from that of the waveguide layer 14 and which has a larger refractive index than that of a clad layer 15 is provided. In such a way, the optical misalignment at the time when a waveguide light travels straight is suppressed, and a crosstalk can be made small.

Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain a stable multiple oxide thin film with improved properties by subjecting sealing treatment with an electrical insulating material to the porous surface or pinholes on a multiple oxide thin film formed on a substrate by hydrothermal synthesis. SOLUTION: First, an autoclave is charged with an aqueous solution of stock metal salt and a substrate followed by heating under pressure to carry out a hydrothermal synthesis and form a multiple oxide thin film 2 on the substrate 1. In this case, the hydrothermal synthesis may be conducted in two stages, i.e., crystal nuclei formation and crystal growth, according as necessary, or may be conducted while vibrating the autoclave perpendicularly. Subsequently, the porous part and pinhole part among crystal grains on the multiple oxide thin film 2 is coated or impregnated with an organic or inorganic electrical insulating material to conduct a sealing treatment. Alternatively, when a metal is used as the substrate, the multiple oxide thin film is treated in an oxidative atmosphere to carry out the sealing treatment so as to form oxide coating film on the substrate metal-exposed part in the pinholes 3.

Title: Current detector and power unit
Inventor: HANEDA SHOJI
IPC: H01F38/28
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a current detector which can detect the current to a load with high sensitivity without changing the current, and a power unit which does not change the current to the load with small loss. SOLUTION: The winding wd for detection of a transformer T is wound around a secondary iron core F2 so that the winding wd may not be inductively coupled with a primary winding w1, but with a secondary winding w2. The secondary iron core F2 is arranged so that the core F2 may not be positioned inside the solenoid formed of the secondary wiring w2, but outside the solenoid. When an electric current transiently flows to the secondary winding w2, a voltage indicating the direction and magnitude of the current is generated between both ends of the winding wd for detection. The ratio of the variation of the voltage across the winding wd for detection to the variation of the current flowing to the secondary winding w2 varies depending upon the magnetic permeability of the secondary iron core F2.

Filed: 1987-11-04
Abstract: PURPOSE:To obtain stable reproducing characteristic by converting a detection output of a detection means detecting the quantity and direction of a movement of a head of a listner into a control data and giving the control data to a change circuit of transfer function and a variable delay circuit so as to vary the transfer function and the delay time. CONSTITUTION:A direction signal Sd changing 0 or 1 depending on the head of the listner turned clockwise and counter clockwise is extracted from a detection circuit 72. Pulses Pa of a number proportional to a varied angle when the listner changes the direction of the head are extracted from a detection circuit 73. Then the signal Sd is supplied to a memory 77 as an address signal to read a control data from the address corresponding to the table in the memory 77. Thus, since audio signals L, R fed to a headphone 6 become a main audio signal and a crosstalk component having a transfer function and a delay time depending on the direction of the head of the listner, the stereo sound field presence equivalent to the stereo reproduction by speakers is obtained.
