Title: Optical fiber for liquid detection and liquid detection system using the same
Inventor: ONO YUTAKA
IPC: G01V8/16
Filed: 1987-08-25
Abstract: PURPOSE:To enable measurement of a liquid such as oil and the position thereof over a long range and in a high section, by using a dual core type fiber having two cores both arranged at such positions as to be small in the optical coupling to each other. CONSTITUTION:A pulse light generated at a light source 16 is made incident into a core 12 arranged at the center position of a cladding 11 via a directive coupler 17 and back scattered light returning through the core 12 is inputted into a processor 20 through a light receiver 19. At this point, a liquid such as oil gets in contact with a part of a sensor fiber 18 and as the surface of the cladding 11 contacts the liquid, a propagation constant of a core 13 changes as arranged at a position close to the surface thereof. A power of a measuring light guided to the core 12 shifts to the core 13 to lower intensity of the measuring light of the core 12. Thus, the intensity of the back scattered light and a time delay are determined, thereby enabling the learning of a part where the liquid contacts the sensor fiber 18 from a bending point of an intensity curve of the back scattered light.

CONSTITUTION:The radial plate type fan comprises a main plate 11b inclining in the axial direction of rotor on the opposite side to a blade 11a, and the blade 11a formed rectangularly to the rotor shaft 6 from the outer diametral end face of a blade on the opposite side to the main plate 11b to the outer diameter of boss, the blade 11a of fan 11 is formed to satisfy following relationships; DI/DO=0.3-0.5, B/D0=0.14-0.2, t/L=1.34, where D0 is the outer diameter of blade, DI is the inner diameter of blade, B is the average blade width, L is the blade length, and (t) is the average blade pitch. This structure realizes a low pressure high flow rate fan 11 having low cut-off pressure and high flow rate within a low pressure range. Consequently, the flow rate can be increased while decreasing the outer diameter of blade significantly, and the driving power and noise of fan can be reduced.

CONSTITUTION:A polyethlene sheet like raw fabric or a tubular raw fabric which contains an antistatic agent in a middle layer and, however, does not contain the antistatic agent in both surface layers, which consists of a homopolymer of ethylene or a copolymer of ethylene and alpha-olefin, is used. For those fabrics, a method in which the sheet like raw fabric is made by extrusion from a T-die, a method in which the tubular raw fabric is made by extrusion from a ring die, etc., are used. Then, after lamination to three layers, crosslinking is performed so that the extent of crosslinking decreases to the center from both sides in a thickness direction of the raw fabric. Thereafter, though it is stretched at least in one direction, corona discharge treatment and or ageing treatment are performed after stretching.

Title: Optical signal processing apparatus
Inventor: TAKAMI MASAYUKI
IPC: G02F1/125
Filed: 1985-09-25
Abstract: PURPOSE:To make it possible to process a more broad-band signal, by integrating a plurality of light deflecting parts on the same-circuit board. CONSTITUTION:Light sources 11, 12 are arranged to the end part of a light waveguide 2 and light deflecting parts 13, 14 are formed on the light waveguide 2 corresponding to said light sources 11, 12. For example, the analysis of the low-pass component of a signal to be measured is performed by the converter of the light deflecting part 3 while the high-pass component of the signal to be measured is analyzed by the converter of the light deflecting part 14. Further, the Fourier transformation image due to the diffracted light from the light deflecting part 13 and the Fourier transformation image due to the diffracted light from the light deflecting part 14 are respectively formed at different positions corresponding to the band-pass regions. Therefore, the light sources 11, 12 and the light deflecting parts 13, 14 are arranged so that the ranges of the advance directions of the diffracted lights become different. As mentioned above, because the light deflecting parts 13, 14 respectively allot the analytical band-passes of the signal to be measured, an analysable frequency band-pass region can be widened.

Title: Brake pressure device for vehicle
Inventor: YUERUGEN BINDAA
IPC: B60T8/00
Filed: 1992-08-07
Abstract: PURPOSE: To prevent braking from becoming insufficient for a rear axle in a curve brake, by making determination of front axle brake pressure by a driver, and controlling rear axle brake pressure so that the angle of side slip of a rear axle may almost meet that of a front axle. CONSTITUTION: The instantaneous gradients mv, mh of a coefficient of friction to a slip curve, which meet a front axle and a rear axle, are determined by providing an axle pressure pva and a wheel velocity Vri for a block 12, thereby delivering them to a comparator 13. The difference is converted into a target signal for a rear axle brake pressure by a stability controller 14. The signal is transmitted to a pressure controller 6 to generate a control signal for an electromagnetic valve 7, thereby controlling the rear axle brake pressure by a rear axle brake 8. The upper limit value psha for the rear axle brake pressure is obtained in response to the ideal brake distribution from the front wheel brake pressure pva to a fully-loaded vehicle 5, and, if the value is exceeded by the target value obtained in the stability controller 14, a switch 14 is switched.  It is thus possible to prevent braking from becoming insufficient for the rear axle in a curve brake, and an effect due to tire tolerances from occurring.

IPC: G01J5/00
Filed: 1992-07-15
Abstract: PURPOSE:To measure film thickness precisely by measuring the alteration of the intensity of light emitted from a thin film being formed and a substrate by a radiation thermometer. CONSTITUTION:In a vacuum container 1, microwave plasma is generated and a thin film is formed. The microwave generated by a microwave oscillator 2 is introduced into the inside of the container 1 through a wave guide 3. A substrate 5 is fixed on a supporting stand 4 which can ascend and discend freely in the inside of the container l and a raw material gas is introduced through a gas leading inlet 6. The gas becomes plasm near the substrate 5 by the microwave and reaction products produced by gas-phase reaction deposits on the substrate 5. Since the temperature is high, light is radiated from the thin film and the substrate. After passing a quartz window 7 in the upper part of the vacuum container, the light is reflected by a mirror 8 and enters a radiation thermometer 9. The intensity of the light which enters the thermometer 9 in this way is measured by a detecting element and the film thickness is computed based on a relation expression.
