Abstract: PURPOSE:To provide an optoelectronic IC for preventing reduction in response speed of a light-receiving element due to extension of an electrode wiring and a circuit operation failure due to a capacitive coupling between circuits and electrode wirings and that with a substrate. CONSTITUTION:In an optoelectronic IC with a light-receiving portion 20 which is formed on a substrate 10, an insulation layer 30 which is formed on the above substrate, an electrode 40 which is electrically connected to the above light-receiving portion 20, and an optical waveguide layer 50 which is formed on the above insulation layer, the above electrode 40 is formed on the above optical waveguide layer 50. By forming the electrode 40 on the optical waveguide layer 50, the capacitance between the electrode 40 and the substrate 10 which are connected to the light-receiving portion 20 is reduced and a capacitor which is inserted into a light-receiving element portion in parallel is reduced, thus enabling reduction in response speed of the light-receiving element portion to be suppressed.

Title: Microwave doppler laser
Inventor: ABIKO TOSHIO
IPC: G01S13/58
Filed: 1980-10-23
Abstract: PURPOSE:To make it possible to perform highly accurate measurement even though relative speed with respect to an object is low, by inputting the reflected wave from the object to a mixer, and supplying the output from the mixer to an amplifier. CONSTITUTION:A fundamental frequency f from an oscillator 1 is multiplied by n times in multiplier 2 and 3, and the signal is transmitted to the object 6 through a circulator 4 and an antenna 5. The reflected wave from the object 6 is received by the antenna 5 and inputted to the mixer 7 through the circulator 4. The signal from the multiplier 3 is also given to the mixer 7. The multiplier 3 sends out the signal having a frequency f4 which is obtained by multiplying the signal of frequency f by (n-m) times. The output from the mixer 3 has the difference frequency (mf+ or -DELTAf) between the reflected wave and the frequency f4, where DELTAf is a doppedler frequency. If m is 1, said difference frequency is f+ or -DELTAf. This signal is inputted to the amplifier 8 and amplified. Therefore the amplification is performed at relatively high frequency, and excellent S/N ratio can be obtained.

Abstract: PURPOSE:To form a silica glass improved in breakage of the mold container during cooling by press forming the original silica glass in a mold container at high temperatures followed by moving the resultant form, within the identical container, to a cooling section differing in dimension from the former section to carry out annealing. CONSTITUTION:A molding container is made up of a molding section 44 with a specified inner surface shape and a cooling section 46 slightly differing in dimension from the section 44 with the both sections partitioned by a shoulder 48. That is, the sectional shape of a punch 14 to apply molding pressure from above corresponds to that of the upper section 44, while the sectional shape of a bearer 16 to that of the lower part of the cooling section 46.

The displacement of the punch 14 and bearer 16 is measured using displacement gauges 50, 50. It is preferable that said punch 14 and bearer 16 be so designed as to control their displacements separately from each other.

Filed: 1978-12-06
Abstract: PURPOSE:To measure a small quantity of oil at a narrow location where there is no dispersion of measurement caused by the change of temperature, by measuring the quantity of the attenuation of the transmitted light of oil by using optical fibers. CONSTITUTION:The one ends of optical fibers 2 for transmitting light and optical fibers 3 for receiving light are soaked in oil to be measured 8. A light source 1 is mounted to the other end of the optical fibers 2 for transmitting light, light 9 is induced to the oil 8 from the optical fibers 2 for transmitting light, and transmitted light passing through the oil 8 is applied to a light receiving element 4 through the optical fibers 3 for receiving light. The light receiving element 4 converts the quantity of light into the quantity of electricity, and swings a needle at ammeter 5. The swing of the needle at ammeter 5 is slight because the more the oil becomes deteriorated the less the quantity of the transmission of light gets. A degree of the deterioration of the oil can simply be evaluated at a narrow position by reading the current value.
