Patent JP-H06118159-A (JP)
Title: Transmitter/receiver
Inventor: TSUBOTA YOSHIHIRO
IPC: G01S7/03
Filed: 1992-10-01
Abstract: PURPOSE:To form a primary radiator and an electric wave detector in one piece on a plane and then to miniaturize a device by constituting a choke structure around an element antenna for reception and an electric wave detector with an MMIC circuit. CONSTITUTION:The electric wave generated by a transmitter 3 is supplied to an element antenna for transmission at an electric wave detector 4 and is radiated as a plane wave by a main mirror 1 through a separation plate 2. At this time, the choke structure around the reception element antenna prevents the transmission electric wave from being leaked to the element antenna for reception. The received electric wave from a target converges at the main reflection mirror 1 and is received by the element antenna for reception at the electric wave detection part 4 through the separation plate 2. At this time, the choke structure around the antenna element for reception prevents mutual interference between the antenna elements for reception. The received electric wave is converted to electrical signal by the detection part 4 for extracting the target by an electric wave signal processor 6. Also, the light wave such as infrared rays from the target converges at the main reflection mirror 1 and the separation plate 2 and is converted to electrical signal by a photo detector 7 and then the target is extracted by a light wave signal processor 8.

Title: Water level measuring instrument
Inventor: SOGABE HITOSHI
IPC: G01F23/00
Filed: 1988-10-21
Abstract: PURPOSE:To prevent reception of an influence from a thunderbolt or a noise by executing signal transmission between a water level detector and a receiver and the supply of energy, which is needed for the water level detector, by the optical fiber cable of one core. CONSTITUTION:A water level signal, which is a measuring subject, is transmitted to a measuring circuit 5 by a water level detecting mechanism 4 and mechanical displacing quantity is converted to an electric signal and sent to an electrooptical converter 6. In the electrooptical converter 6, the electric signal is further converted to the optical signal of a frequency f2 and sent through an optical fiber 3 to a photoelectric converter 7 in the internal part of a receiver 2. Then, the optical signal is converted to the electric signal and after that, it is restored to the water level signal by a decoder 8. Electric energy P to be needed in the internal part of the water level detector 1 is converted to the optical energy of a frequency f1 from a power source 9 in the internal part of the receiver 2 by an electrooptical converter 10. After that, the energy is passed through the optical fiber 3, converted again to the electric energy by a photoelectric converter 11 and supplied from a power source circuit 12 to respective parts. Thus, the water level can be measured without being affected by the thunderbolt or noise.

Title: Waveguide type wavelength variable filter
Inventor: ONO TAKEO
IPC: H01S5/042
Filed: 1989-10-12
Abstract: PURPOSE:To control a selected wavelength at high speed by making a semiconductor substrate and a waveguide layer in the same conductive type and providing corrugation on the inside of the waveguide layer. CONSTITUTION:The semiconductor substrate 11 and the waveguide layer 14 are made in the same conductive type and the corrugation is provided on the inside of the waveguide layer. Namely, in the waveguide layer where the corrugation is provided on the inside, the wavelength is selected by performing the feedback of distribution by the diffraction action. When a voltage which is reverse bias is impressed between the respective electrodes from such a state, a depletion layer 17 is expanded in the waveguide layer in accordance with the magnitude of the reverse bias voltage and refractive index in the waveguide layer is changed, so that the wavelength obtained by performing the feedback of distribution becomes different as well. Since the substrate 11 and the waveguide layer 14 are made in the same conductive type, a current does not flow between them and fault caused by temperature rise is prevented. Thus, the selected wavelength is stably controlled at the high speed.

Abstract: PURPOSE:To shorten a height dimension and slider guides by only permitting the slider guides to restrict the sliders which are positioned last, permitting the sliders to pass prescribed tracks and preventing them from being directly coupled with a driving mechanism at the time of shifting from a cassette position to a set position. CONSTITUTION:When a ring 20 starts rotating, drawing pins 6 and 7 and a first slider 18 draw the magnetic tape 4 from a cassette case 3. Since a second slider 19 is not directly coupled with the ring 20 at that time, it is set to stand by in the cassette position. The first slider 18 and the second slider 19 are in places apart with a distance equal to a final set state, and a pin 26 presses against the second slider 19 which stands by, pushes the second slider 19 along the tracks of slider guides 23 and 24, and reaches to a final set position. Accordingly, the first slider 18 is simultaneously positioned in the final set position. Thus, the height and the slider guides can be shortened.
