Title: Controlling device for clutter
Inventor: SHINONAGA MITSUYOSHI
IPC: G01S7/32
Filed: 1981-03-19
Abstract: PURPOSE:To remove a moving clutter by estimating accurately the central frequency of the moving clutter in a radar and by determining the intercepting band-width of a moving clutter-removing filter in accordance with the power spectrum-width of the moving clutter. CONSTITUTION:A moving clutter extracted by a fixed clutter-removing filter 11 is supplied to a moving clutter-removing filter 12 and a phase-angle measuring unit 13. An averaged phase angle of the moving clutter is operated in the measuring unit 13 and supplied to a central phase angle estimating unit 14, wherein a central phase angle phi is estimated. This angle phi is supplied to the filter 12 and thereby the intercepting band of the filter 12 is determined. The phase angle and estimated value of remaining clutters passing through the filter 12 are supplied to a phase-angle comparing unit 15, the powers P2 and P1 of the clutters whose phase angle are larger or smaller than phi are separated and added, and an error signal is delivered. This error signal is sent to the phase angle estimating unit 14 and thereby the angle phi is corrected. The residual clutters whose powers P1 and P2 are almost equal remain thereby, and then, by expanding the intercepting band-width of the filter 12 equally to the distribution of the phase angles of P1 and P2, the moving clutter is removed.

Abstract: PURPOSE:To make an optical fiber compact by constituting a core part of a material having a less transmission loss of IR light and an outside circumferential part of a material having a less loss of visible light thereby transmitting the IR light and the visible light with the same optical axis at the same time. CONSTITUTION:The material which permits the easy transmission of the IR light as energy and allows hardly the transmission of the visible light is used for the core part 1 of the optical fiber and the material which allows hardly the transmission of the IR light and allows the easy transmission of the visible light is used for the annular outside circumferential part 2. The position for irradiation is determined by inputting laser light of He-Ne2mW into the composite fiber from the input end thereof and obtaining the annular red light from the output end thereof. A 10WCO2 laser is inputted into the AgBr part of the core part to heat exactly the required part. The IR light and the visible light are therefore simultaneously transmitted with the same axis by which the fiber is made compact and the application thereof to a smaller part is made possible.

Abstract: PURPOSE:To make it possible to control the flow of a water surface and to make a device an OEIC easily as to adopt a multiple quantum well(MQW) structure for an active layer, by forming a first region to form a p-n junction by ion implantation or by both ion implantation and form a p-n junction by ion implantation or by both ion implantation and thermal diffusion. CONSTITUTION:Using an SiN film 6 as a mask, selective diffusion is conducted from above a wafer on which a clad layer 2, an active layer 3, a clad layer 4 and a contact layer 5 are deposited in this order, to form an p<+> diffusion area 7 as a second region. Nextly, the contact layer 5 near an p<+>n junction is removed by etching and ions are implanted to form a (p) ion implantation region 9 as a first region. After that, a device is annealed and the SiN film 6 is removed to recover the device from a damage including lattice defect caused by ion implantation. Then, an (n) electrode 11 and a (p) electrode 12 are formed to complete the device. By this method, a time-consuming high temperature driving process can be omitted and the wafer surface is kept from becoming rough and the device can be made an OEIC easily. Even if an MQW structure is adopted for an active layer, a high-efficiency TJS laser can be gained without losing the order.
