Title: Two-cycle internal combustion engine
Inventor: NAKAMURA NORIHIKO
IPC: F02M69/10
Filed: 1989-09-20
Abstract: PURPOSE:To control the injected fuel quantity accurately by leading scavenging air pressure into a pressure regulator for regulating fuel pressure increasing the fuel pressure according to the increase of the scavenging air pressure, and injecting fuel into a cylinder from a fuel injection valve at the specified time. CONSTITUTION:A pair of air supply valves 6 are disposed facing a recessed groove 5 formed at the inner wall surface 3a of a cylinder head 3, as well as a pair of exhaust valves 7 are disposed on the approximately plane inner wall surface 3c excluding the recessed groove 5, and a fuel injection valve 18 is disposed at the peripheral part of the inner wall surface 3b below the air supply valve 6. This fuel injection valve 18 is supplied with fuel delivered from a fuel supply pump 23 and regulated in pressure by a pressure regulator 24. In this case, pressure in a surge tank 17 is led into a spring chamber 26 partitioned by the diaphragm 25 of the pressure regulator 24, through a conduit 29. Fuel injection is performed within the period between the time when the air supply valve 6 is opened and the time when the pressure in the spring chamber 26 becomes approximately equal to that in a combustion chamber 4 after the air supply valve 6 is closed.

Title: Flow control apparatus
Inventor: MORIUCHI YOSUKE
IPC: A61M5/14
Filed: 1987-09-24
Abstract: PURPOSE:To prevent the remaining of air in a flow control apparatus, by guiding a fluid such as a physiological saline solution to a bent or curved flow passage communicating with the flash passage demarcated between a flow rate limit member and an elastic tubular body by deforming the elastic tubular body. CONSTITUTION:The recessed parts 62a, 62b formed by partially cutting the upper part of an elastic tubular body 42 function as a flash passage when the elastic tubular body 42 is deformed and blocked in a usual state by the protruding part 64 of the elastic tubular body 42. A flow rate limit member 44 is inserted in the hole 60 of the elastic tubular body 42 and the protruding part 64 is brought into contact with the central region thereof. This flow rate limit member 44 has a through-hole 66 having a fine diameter. When the press parts 52a, 52b provided to the housing 40 of a flow control apparatus 18 are grasped by fingers to be pressed, the protruding part 64 is separated upwardly and, therefore, a gap is generated to allow the recessed parts 62a, 62b to communicate with each other and a flow passage is opened as the flash passage. The physiological saline solution introduced through a tube 16 passes through a passage 70 in a bent state and flows through the passage 78 on the side of a lead-out pipe 48 through the flash passage to be led out to a tube 20 through the lead-out tube 48.

Abstract: PURPOSE:To make the passage of a medium satisfactory by stopping a sector shape pay-out roller in the lower parts of a plurality of hoppers, at a position where the ridge of the forehead side thereof having a sector cross-sectional shape is flush with a conveying surface when a medium paid out from the following hopper is conveyed from the conveying surface. CONSTITUTION:A medium 41 paid out from a following hopper and conveyed is led into a gap 10b between a next hopper pay-out roller 3b and a stack 4b of mediums. At this time, the pay-out roller 3b makes such an angle that a planar 3b' on the leading side forehead having a sector cross-sectional shape scoops the medium, with respect to the conveying direction, and is stopped at a position where a slope 2b and the ridge 3b'' are substantially flush with each other. Accordingly, the leading end part 411 of the medium 41 runs along the planar part 3b' so that the medium may be smoothly led into the gap 10b, and may be guided overriding a height difference between the slope 2 and the conveying surface 11b by the pay-out roller 3b, thereby it is possible to stabilize the passage of the medium 41.

Abstract: PURPOSE:To correct the accuracy of a platen and stabilize printing quality, by providing a support means, a driving means and a position-detecting means at each end of the platen, and driving the driving means based on the result of detection by the position-detecting means. CONSTITUTION:Starting from the condition where a platen 1 is retracted, vertical driving and lateral driving are synchronously performed. When the platen 1 is out of parallelism and is in a posture lower in its left side, the platen 1 first comes into contact with a right switch 17b to turn ON the switch 17b, whereas a right driving motor 12b is turned OFF, and a right part of the platen 1 is stopped at a reference position. At this time, a left switch 17a is in an OFF state, so that a motor 12a continues driving the left part of the platen 1, and the position of the left part of the platen 1 is stopped when the switch 17a is turned ON. Thus, the parallelism of the platen 1 is ensured, and thereafter, the left and right motors 17a, 17b are synchronously driven, whereby highly accurate positioning can be performed.
