Abstract: A non oil coated construction form is disclosed. It is composed of a pair of struts and a flat plate with its rear surface fixed successively with a plurality of nailed joints to the struts, the plate is made of braided hemp fiber impregnated in phenolic resin and hardened. After drying, cooling, cutting and thermocompressing to be formed into a laminated phenolic compound resin material with intensified mechanical strength and a flat smooth surface. The form of the present invention is stronger, more easily detachable, durable and cost saving compared to a conventional lumber form. In addition, owing to flatness and smoothness of its surface, the surface of the concrete body does not have to be buffed after removal of the form of the present invention.

Abstract: A direction changing device for a handle of a stroller comprises a main body, a pulling rod and a co-moving part; the handle is fixed to the main body, which is capable of pivoting on a fixing element of a support member of the stroller. The main body has a hollow, in which the co-moving part is movably received. The pulling rod has a hooked end engaging a slope of the co-moving part. The co-moving part has two concavities each communicating with a confining end of the hollow to form two locating holes for a locating pole of the support member to be passed thereinto. The locating pole engages either one of the concavities to prevent the main body from turning. When the pulling rod is pulled, the co-moving part will be moved further into the hollow for releasing the concavities from the engagement with the locating pole. Thus, the main body plus the handle can be pivoted to change direction of the handle.

Abstract: A photo-detector based calculating means having a grating wheel with integrated lenses is provided. The photo-detector based calculating means having a grating wheel with integrated lenses includes a light source (1), a grating wheel (2), and a photo-detector (3), with the light emitted from the light source (1) impinging upon an input plane of the grating wheel (2). The photo-detector (3) has a set of photo-sensitive chips (31) to receive the working light beams emitted from the grating wheel (2). The input plane of the grating wheel (2) has a ring-shaped lens (24) to focus the light emitted from the light source (1). The output plane (23) of the grating wheel (2) has a plurality of tooth-shaped lenses (25), each projecting perpendicularly to the ring-shaped lens (24), which can focus the working beams after the working beams pass through the output plane (23), thus minimizing interference.

Abstract: A caster of a collapsible crib includes a wheel and an outer cover fixed to the bottom of the crib. The wheel is rotatably housed within the outer cover. The outer cover has a supporting block, which is arranged such that the wheel is a distance from the ground when the crib is held upright on the ground, i.e. the supporting block touches the ground instead of the wheel.The crib is provided with two above described casters and two supporting base members so that it can be normally supported upright with four points; while the crib, when collapsed, can be leant on a user hand so that it is supported with only wheels of the casters to be capable of moving erasily.

Abstract: A supporting structure, comprises a first plate including a rectangular upper surface and two side walls bridged along the lengthwise sides of the upper surface with folded line therebetween and vertical to the upper surface, the first plate having two first embedding slots parallel to the shorter sides thereof and extending over the side wall, and a second plate including a rectangular bottom surface and two side walls bridged along the lengthwise sides of the bottom surface with folded line therebetween and vertical to the bottom surface, the second plate having two second embedding slots parallel to the shorter sides thereof and extending over the side wall; a through hole being provided between the second embedding slots connected with the second embedding slots.

Abstract: A water-sealing switch structure of wall-type faucet, including a main body, a pull rod, a water sealing seat and a water sealing ring. A front end of the main body is formed with a spout. An inner rear side of the spout is disposed with a close wall formed with a water outlet. Two sides of the spout are respectively disposed with two restricting plates. A top edge of inner front side of the spout is disposed with a guide post formed with a through hole. An upper end of the pull rod is disposed with an enlarged head section. A lower end of the pull rod is disposed with a tapered conic post. An upper side of the conic post is formed with a small diameter engaging section. A lower end of front side of the water sealing seat has a projecting U-shaped engaging seat. A rear side thereof is disposed with a projecting ring. An inner lower edge of the projecting ring is disposed with a draining channel.

Abstract: A folding, structure for a collapsible stroller of the present invention has a pair of pivotal connectors, a pushing handle, two front support rods, two rear support rods, a pair connecting holder blocks, a chair back frame and two connecting rods. The pivotal connectors pivot the pushing handle, the front support rods and the rear support rods. The connecting rods with one end respectively pivot to the pushing handle and the front support rods and with the other end pivot to the connecting holder blocks. The chair back frame also pivots to the connecting holder blocks. Each of the rear support rods has an obstructing protrusion and pivots the connecting holder block. Each connecting holder block has a press block, the first press bar, the second press bar, a hole, the first sloped guide surface and the second sloped guide surface.

Abstract: A collapsible stroller is provided for transporting a child. The stroller has a push handle, and supporting members capable of pivoting relative to one another such that the stroller can be folded or expanded. A connecting block is movably connected to a first one of the supporting members, and can move along with the push handle; the first supporting member has an engaging protrusion capable of resiliently engaging the connecting block to stop the same from moving when the stroller is disposed in the expanded position; the connecting block has a pressing block, which, when depressed, can urge the engaging protrusion to move into the first connecting member for permitting the connecting block to be moved downward along with the push handle in order to fold the stroller.

Abstract: A rotating field, synchronized electric generator or motor in which the magnetic field that the armature produces can rotate relative to the stator at a speed significantly different from that of the armature, under electronic or other control that obviates the need for a mechanical torque-carrying gearbox that can be used for a similar purpose in a synchronized generator or motor.

Abstract: A retractable handle device is provided which includes two sleeves, two inner tubes disposed in the corresponding sleeves, and a handle mechanism that respectively receives the inner tubes on opposing ends thereof. Two position-control devices are located at the bottom end of corresponding inner tubes. The handle mechanism has a press bar mounted in a lower casing thereof. Each position-control device has a locating block fastened to the bottom end of the corresponding inner tube, a flat latch, biased by a spring, engaging a locating hole on the corresponding sleeve to stop the respective inner tube from axial movement relative to the corresponding sleeve.
