Title: Fiber reinforced plastic impeller
Inventor: HINO SHOJI
IPC: F04D29/02
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce the stress of a joint part between a blade and a core side plate by determining a content of fiber in FRP forming the blade, high in a joint part between the blade and a core plate and that between the blade and a side plate, and low in an area separated from the joint part. SOLUTION: In the analyzation of the stress generation mechanism on a joint part between a blade and a core side plate where the stress of a FRP centrifugal impeller becomes highest, the stress caused by the centrifugal force of a central part of the blade occupies the largest ratio. Accordingly by lowering a content of fiber in the central part of the blade and reducing the centrigugal force of this part, a bending moment of the joint part with the core side plate is reduced. On the other hand, by increasing the content of the fiber in the joint part with the core side plate and increasing the strength of this part, the strength of the impeller can be totally improved.

The gear 6 rotates the reel 3 and a tape to be carried at a constant speed by the capstan and a pinch roller is wound on the reel 3. At the time of rewinding, the capstan and the gear 9a reverse the gear 7 separates from the 6 and engages with a 20 and the supplying side reel 4 rotates and winds the tape. At this time, when the diameter of the gear 20 is made large, its lateral pressure FS (gear loss) becomes lower than the lateral pressure FT of the gear 6, the torque of the reel 4 increases and the rewinding can be attained enough.

Abstract: PURPOSE:To correct an error and to understand a true value by modulating a transmission wave by a prescribed frequency, varying a frequency of the transmission wave itself between prescribed values, calculating an obtained value and deriving a distance. CONSTITUTION:An oscillator 12 is brought to oscillation by frequencies (f0 - f1) based on a carrier wave frequency adjusting signal outputted from a data processor 13, and brought to AM modulation by a modulator 15 by a signal fm of a modulation signal generator 14. The modulated signal is sent out of a transmission antenna 10, reflected by the ground and reaches a reception antenna 11 by being delayed by the time (2l/c second, (c) denotes a velocity of light) determined by altitude (distance (l)) of an unmanned helicopter 1. An output signal passes through an amplifier 16 and detected by a detector 17, and only a modulation component is fetched. Subsequently, phases of the detected signal and a signal from the generator 14 are compared by a detector 18, inputted to the processor 13, and the distance (l) is derived by calculating it. By varying and measuring the wavelength lambda and averaging all the measured values, the true value can be obtained.

Title: Multi-layer type strainer

IPC: B01D35/02
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To simply and inexpensively produce a multi-layer type strainer while arbitrarily setting the opening ratio thereof and to make the clogging of the strainer caused by earth and sand particles hard to generate. SOLUTION: A multi-layer type strainer has such a structure that a large number of annular parts 12 and spacer groups each consisting of more than three spacers 14 arranged in the peripheral direction of each annular part are stacked so as to be alternately positioned in an axial direction and slit-like openings 16 through which ground water flows are formed between the annular parts mutually adjacent to each other by the spacer groups. The annular parts may have a polygonal annular shape. Each annular part and the spacers may be formed as an integrated structure or as a combination of separate members.  It is preferable that an inlined surface is formed to one surface or both surfaces in the axial direction of each annular part in a direction wherein the axial dimension of the annular part becomes short from the outer peripheral edge thereof toward the inner periphery thereof and the slit width of each opening has a vertical cross-sectional structure narrow on the outer peripheral side and expanded on an inner peripheral side. Since earth and soil particles entering the slitlike opening fall inside by the inclined surface, clogging becomes hard to generate.

Abstract: PURPOSE: To facilitate manufacture of a reflector and a lens, and to aim to prevent hanging down of right and left edges of luminous intensity distribution characteristics, by forming inclined surfaces in the right and left, and up and down directions of a headlamp on plural sections in oblong shapes which are longer than are wide, formed by dividing a lens, and by forming the headlamp so as to correspond to the size of an image after being reflected on a reflector. CONSTITUTION: A lens 4 is divided into plural sections 40a, b... in oblong shapes which are longer than are wide, and formed so as to have a ridged shape having inclinations in the right and left directions, and simultaneously to have a thick upper part. The direction of travel F of a motor vehicle is, at the same time, the direction of irradiation of a headlamp 1, and the upper edge side of the lens 4 is inclined backward with an angle of inclination α, and a parallel ray S, which is roughly parallel to the direction of travel F, enters the sections 40a, 40b, respectively.  In addition, a plane 41R is formed in a prism-like shape, having a rightward deflection angle γ by which the parallel ray S is deflected to the right side of the direction of travel F by a desired declination θ, but in order to correct a downward declination caused inevitably by the angle of inclination α, the wall thickness on the upper edge side of the lens 4 is increased and an upward deflection angle δ is prepared. Consequently, metal mold manufacture of the lens is facilitated and luminous intensity distribution characteristics can be adjusted simply by the change of a pitch.

Title: Slip control device for vehicle
Inventor: TSUYAMA TOSHIAKI
IPC: B60T8/175
Filed: 1989-12-06
Abstract: PURPOSE:To prevent unstabilization of a vehicle at the initial time of acceleration by giving equal braking force to right and left drive wheels before the vehicle reaches a predetermined running condition after starting and individually independent braking force in accordance with a slip amount to the right and left drive wheels after the vehicle reaches the predetermined running condition. CONSTITUTION:After a vehicle is started, in the case of its speed not reaching a predetermined value, in a control unit UTR, an integrated control for applying an equal brake to right and left drive wheels is performed by judging the vehicle not placed out of the acceleration initial condition just after starting. That is, when a slip value of the drive wheel is in not less than a brake controlling target value SBT, being based on the larger slip value of the right and left slip values, braking force necessary for reducing this slip value to a target slip value is simultaneously applied to the right and left drive wheels. When the slip value of the drive wheel is less than the SBT, a brake fluid pressure of the right and left drive wheels is gradually reduced. After the car speed reaches the predetermined value, individually independent braking force in accordance with the slip amount is applied to the right and left drive wheels.

Abstract: PROBLEM TO BE SOLVED: To form so that an oil surface can be seen from an oil supply port and prevent the excess of a supply oil amount by installing the oil supply port to an oil separator so as to open at the upper limit oil surface position of an oil stored its inside. SOLUTION: An air compressing device is provided with an oil separator 6 for separating an oil from a compressed air compressed by an air compressor 1 and a hydraulic circuit for returning a separated oil to the intake side of the air compressor 1. An oil supply port 30 is installed on the oil separator 6 through an oil supply pipe 31 so as to open at its upper limit oil surface position UL. The oil supply port 30 is closed by a cap 32. When the oil O in the oil separator 6 is reduced, the oil O is supplied from the oil supply port 30 after removing the cap 32. Thereby, when the oil surface OL of the oil O inside the oil separator 6 is risen and reaches the upper limit oil surface UL, this oil surface OL can be seen from the oil supply port 30. Thereafter, the excess of a supply oil amount can be prevented by stopping the supply of the oil O.
