Title: Optical isolator
Inventor: TOJO MASAAKI
IPC: G02B6/42
Filed: 1987-10-01
Abstract: PURPOSE:To obtain an optical isolator being suitable for miniaturization by providing a superconductive film in a shape of a ring on a YIG thin film crystal, allowing a current to flow to this ring and generating a magnetic field. CONSTITUTION:On yttrium iron garnet (YIG) thin film crystal 1, a superconductive substance is formed in a shape of a ring by sputtering, etc., and by allowing a large superconductive current 7 to flow to its ring 2, a large magnetic field 8 is generated. Accordingly, when a light beam is made incident in the same direction as the magnetic field 8, a plane of polarization of the light beam rotates. An optical isolator which has been constituted in such a way can be thinned extremely. A light beam which has been emitted from a semiconductor laser 4 transmits through the YIG thin film crystal 1 through a rod lens 3, transmits through an analyzer 5 and made incident on an optical fiber 6. It is return light beam passes through the YIG thin film crystal 1 two times, therefore, the plane of polarization of the return light and the plane of polarization of the emitted light are orthogonal to each other and do not interfere with each other. Accordingly, the semiconductor laser 4 executes a stable light emission.

Title: Mimim element
Inventor: TAKAHASHI MASAYOSHI
IPC: H01L49/02
Filed: 1990-09-19
Abstract: PURPOSE:To improve the reliability and transistor characteristic of a MIMIM element by limiting the active section of the element with a patterned insulating layer so as to easily fix the area of the active section. CONSTITUTION:After the first electrode 2 is formed on a substrate 1, the first insulating layer 3 composed of a hard carbon film is formed on the electrode 2 so that the electrode 2 can be covered with the layer 3. An active section limiting insulating layer 7 is formed by patterning an insulating layer 3 so as to limit the active section of this MIMIM element after the layer 7 is formed on the layer 3. After the layer 7 is formed, the second electrode 4 and second insulating layers are successively formed. Since the active section is limited by the insulating layer 7, no foreign matter gets into the insulating layer of the active section and the transistor operation of this element are stabilized and ensured. Moreover, since the layer 7 exists in the sections other than the active section, an emitter and base can be surely insulated front each other.

IPC: H03L1/02
Filed: 1985-11-07
Abstract: PURPOSE:To always secure the satisfactory frequency/temperature characteristics by detecting the change of the ambient temperatures to compensate this change with output of a compensating digital code and then changing the gain of a DC amplifier to compensate the change of the working point against the input of the control voltage. CONSTITUTION:A voltage controlled piezo-oscillator is obtained by connecting a piezo-oscillator 1 to a variable capacity diode 2. A temperature detector 10, the 1st A/D converter 8, a memory circuit 7, a D/A converter 6 and a digitally controlled DC amplifier 5 are connected in series to the one side of the diode 2. Thus a compensating circuit is obtained to the ambient temperatures. While VAFC is turned into a digital code by an A/D converter 9 and the gain of the amplifier 5 is controlled. Thus a compensating circuit is obtained to the input of VAFC. The change of the load capacity for compensation of temperature can be changed as shown by A-C because the gain of the amplifier 5 can be controlled by VAFC. This secures the satisfactory frequency/temperature characteristics.
