Title: Arm load control device for wiper
Inventor: FUKATSU YOSHIAKI
IPC: B60S1/32
Filed: 1986-03-05
Abstract: PURPOSE:To reduce noise due to contrarotation while the satisfactory wiping action of a wiper is being maintained by moving a cam driven member while the contact is being kept with a cam surface by the rotation of the cam whereby releasing a spring when the cam driven member reaches the end section of the cam surface. CONSTITUTION:When a wiper arm W.A is swung around the axis line of a pivot 2 by means of the reciprocal rotation movement of the pivot 2, a cam roller 5a rotates while coming in contact with a cam 4, furthermore the cam roller 5a fits into a recess on one side of the cam 4 when the wiper arm W.A reaches a reverse point. At this moment, both a cam rod 5 and a driving bellows piston 7 are moved to the left. And a driven cylinder 11 is also moved to the left with respect to the bent section 16a of a piece 16 by means of the action of a compression spring 13. As a result, the extension section 11a of the driven cylinder 11 is moved to the left, and as the force of the spring 13 to push the bent section 16a to the right is decreased, arm load is decreased for preventing noise due to contrarotation.

Title: Liquid fuel combustion device
Inventor: OOMUKAE SHIYOUZOU
IPC: F23D3/14
Filed: 1979-04-17
Abstract: PURPOSE: To control a combustion capacity by regulating a flow rate of air and obtain a stable and clean combustion by a method wherein an air flow regulator capable of variating the flow rate of the air supplied to a fuel vaporizing portion from a blasting means is equipped.  
     CONSTITUTION: Fuel from a fuel supplying portion 9 to a vaporizing portion 3 is supplied by a lift of capillary action of a porous body A, therefore, a vaporizing amount and a supplying amount thereof are coincided correctly. Air supplied by a fan 11 is supplied to the vaporizing portion 3 through holes of a partitioning plate 14 after regulated by a flow regulator 12. According to such a constitution, a vapor pressure near the fuel vaporizing portion 3 of the porous body A is varied in accordance with a quantity of the air passing through the holes of the partitioning plate 14 and, for instance, when the air flow is increased and the vapor pressure is decreased, a more quantity of the fuel is vaporized. A reversed case can be existing. Thus, a combustion capacity is varied in proportional to the air supplying rate, therefore, a ratio between the air and the fuel in a mixture and a temperature thereof may be kept in constant and a stable combustion may be effected.

Title: Continuous output rider for pseudo random modulation
Inventor: TAKEUCHI NOBUO
IPC: H04B10/524
Filed: 1982-03-27
Abstract: PURPOSE:To derive a distance irrespective of a speed of a target, and also to derive its moving speed at the same time, by combining CW laser light with an optical system which is capable of adjusting an overlapping function of a field of view, by use of an encoded pulse train modulated by a pseudo random signal. CONSTITUTION:CW laser light from a laser 11 of a transmitting part 10 becomes an encoded pulse train modulated by a pseudo pulse from a pseudo pulse signal generator 13 by a modulator 12 and is transmitted. Subsequently, it is diffuse-reflected by a scattering body 30 and is photodetected by a photodetector 21 of a receiving part 20 which is capable of adjusting an overlapping function of a field of view by detecting a minimum detecting distance by which an overlapping function of a field of view of transmission and reception is varied to positive from ''0''. A photodetecting signal from the scattering body 30 which is distant from the shortest distance from this detector 21 is correlated with a pseudo random signal adjusted by a delay time from the generator 13, by a delay correlator 22. In this way, by a stable CW operation, a distance is decided irrespective of a speed of a target without executing a switching operation which causes generation of a noise. In this regard, when multi-wavelength is sent out simultaneously, a speed of the target is also decided simultaneously by a Doppler effect.

Title: Structure mirror further varying distorted image
Inventor: SAITOU SHIYOUICHI
IPC: G02B26/08
Filed: 1983-03-22
Abstract: PURPOSE:To project a polygonal distorted image in motion by varying the direction of distortion of the image gradually according to the angles of the curved surfaces of curved mirrors during rotation. CONSTITUTION:When a motor 9 is driven, its rotation is transmitted to an input shaft 16 by the output shaft of the motor and then transmitted from a miter gear 15 fixed to the input shaft to the miter gear 15 of shafts 3 and 3, which are driven. Thus, the shafts 3 and 3 rotate, so curved surfaces mirrors 2a and 2b rotate together with the shafts 3 and 3. The curved surface mirrors refract and reflect light to distort images by themselves, and vary in direction of refraction and reflection according to the rotation of the curved surface mirrors. Consequently, the images of the curved surface mirrors vary in direction of distortion gradually to provide variation and motion to the profiles and expressions of the images.

Title: Manufacture of fiber reinforced composite material
Inventor: DEMURA AKIHIRO
IPC: C08J5/04
Filed: 1987-03-02
Abstract: PURPOSE:To obtain a fiber reinforced composite material, without selecting a matrix as a filler and capable of coping with any complicated configuration highly accurately and efficiently, by forming the cured substance layer of thermosetting resin on the outer surface of the fiber reinforced composite material excluding a part of a precursor. CONSTITUTION:The cured substance layer of thermosetting resin, not softened and not flowing out upon carbinizing and not impregnatable, is formed on the outer surface of one part of a three-dimensional structure consisting of carbon fibers mainly by spraying, dipping, brushing or the like of the thermosetting resin to obtain a resin curing vessel as a whole. According to this method, the amount of matrix for filling may be minimized. Even when coal based or petroleum based heavy oil, tar, pitch or the powder of these materials or the like, which is comparatively inexpensive and softened or flows out upon carbonizing, is used as the matrix, the cured substance layer of the thermosetting resin, not softened or flowing out upon carbonizing, is formed excluding one part of the three-dimensional structure or the precursor of a composite material, therefore, the outflow of the filled matrix may be precluded and cutting process as well as final precise machining process for each impregnation- carbonizing is unnecessary.
