Title: Apparatus and method of measuring minute change of liquid level
Inventor: MIWA YUKIO
IPC: G01F23/24
Filed: 1992-02-20
Abstract: PURPOSE:To accurately measure the change of the liquid level so as to detect the leakage of even a very small amount of liquid. CONSTITUTION:As a table 3b of a rope moving means 3 securely holding a rope 1 is advanced, a detecting electrode 2a consisting of a needle-shaped inner electrode 21 and a cylindrical outer electrode 23 is brought into a to-be-measured liquid 4 from the liquid surface. Then, when a detector 2b senses that the inner electrode 21 is in touch with the liquid surface of the liquid 4, the table 3b is stopped. The position of the table 3b is accurately read by a sub scale 3a and a micrometer 3c based on an origin L0. A predetermined time later, the position of the liquid surface is measured again. The measurement is repeatedly carried out, so that the moving amount L1 of the table 3b is read accurately. The change of the level of the liquid 4 is measured from an expression (origin L0-moving amount L1).

Title: Digital reception system
Inventor: HONDA MASANORI
IPC: H04L27/227
Filed: 1984-02-24
Abstract: PURPOSE:To always pass an intermediate frequency signal through the center frequency of a band pass filter by controlling a reception local oscillator and a voltage control oscillator on the basis of the oscillation frequency of a highly stabilized intermediate frequency oscillator. CONSTITUTION:The reception input signal supplied to a terminal 9 is amplified by a high frequency amplifier 1 and mixed with the output wave fed from a reception local oscillator 14 by a reception mixer to be converted into an intermediate frequency signal. This signal is amplified up to a prescribed level through a BPF4 and an intermediate frequency amplifier 5 containing an automatic phase controller and then undergoes phase detection through a phase detector 6 by means of the output wave of a voltage control oscillator 11. Thus a base band signal is extracted at a terminal 10. The phase comparison is carried out between a partial output of the oscillator 11 and the output wave of a highly stabilized intermediate frequency oscillator through a phase comparator 13 to obtain error voltage. Both oscillators 14 and 11 are controlled by said error voltage to obtain the prescribed value for both the frequency of an intermediate frequency signal and the oscillation frequency of the oscillator 11. The variance component of the intermediate frequency signal is absorbed by varying the oscillation frequency of the oscillator 14. Thus the intermediate frequency signal always passes through the center frequency of the BPF4.

IPC: G02B6/42
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To decrease the number of optical components and to reduce crosstalk by allowing an optical fiber to include plastic materials as its core materials and equalizing the relative positions of the cores from the light incidence end to the light projection end of the optical fiber. SOLUTION: A bundle type optical fiber 10 has core bundles put in one optical fiber and a clad having a lower refractive index than the cores is charged between the cores. Light is confined to the individual cores and propagated. Here, the bundle type optical fiber 10 in use has, specially, the position relation between the cores held from the incidence side to the projection side. Therefore, the beam from a surface light emission laser array 30 which is made incident on the bundle type optical fiber 10 is projected having the position relation maintained, so signals from respective lasers can be detected distinctively by using an optical detector array 50 made to correspond to the laser positions of the surface light emission laser array 30. In this case, plastic materials are used for both the cores and clad.

Filed: 1985-02-23
Abstract: PURPOSE:To enable prevention of enriching of an actual air-fuel ratio, by a method wherein, in a double O2 sensor, when an O2 sensor on the downstream side is brought into an inactive state, control of air-fuel ratio feedback is stopped. CONSTITUTION:In a control circuit 10, first and second active/inactive discrimi nating means compare outputs from O2 sensors 13 and 15 with a monitor voltage by means of which the O2 sensor is activated, and this discriminates whether the O2 sensors 13 and 15 are respectively brought into an active or an inactive state. As a result, an air-fuel ratio regulating means regulates an air-fuel ratio according to outputs from both the O2 sensors 13 and 15 when the O2 sensors 13 and 15 on the upper stream side and the downstream side are both in an active state and according to an output from the O2 sensor 13 and 15, being in an active state, when either of the O2 sensors is in an active state. Especially, when the O2 sensor 15 on the downstream side, positioned closer to the low temperature side than the O2 sensor 13 on the upper stream side, is in an in active state, an actual air-fuel ratio is prevented from being enriched due to the above state.
