Title: Reel base driver for tape recorder
Inventor: MIYAMOTO HIROYUKI
IPC: G11B15/26
Filed: 1989-04-13
Abstract: PURPOSE:To absorb the fluctuation of torque of a motor and to make a special frictional force applying member unnecessary by making one stretched part outer side surface of elastic belts stretched to a pair of driven pulleys in parallel into a semi-wound state. CONSTITUTION:When a reel motor rotates in the direction of an array 16, an arm 6 is turned and energized in the counter-clockwise direction, the outer surfaces of belts 14 and 15 wound around a driven pulley 10 is pressured to a reel base 4, and the stand 4 is turned in the direction of an arrow 36. The torque fluctuation of the motor 5 is absorbed by the expansion/contraction of the belt, and the wow and flutter characteristic of a tape recorder is improved. The turn force of the arm 6 is generated by the tension difference of the belts 14 and 15 due to the normal rotary load of pulleys 10 and 11, and since a frictional member such as felt is not used, the turn force is stabilized for a long time. The arm 6 is pressured to the reel stand 3 due to the inversion of the motor 5, the stand is driven in the winding direction, and reverse recording/reproducing can be executed.

Abstract: PURPOSE:To obtain a uniflow scavenging having little blow-by of a fresh air without requiring a valve operating device, by forming a scavenging valve opened by the pressure in a crankcase to the upper side of a cylinder, while opening a scavenging port opened and closed by a piston to the lower side of the cylinder. CONSTITUTION:When a piston 2 is lowered in the cylinder 1 of an engine, a mixture gas in a crankcase 5 is compressed. The compressed mixture gas goes to a scavenging port 22 passing through a scavenging hole 24 and a scavenging passage 23. The inside of the crankcase 5 is communicated to a pressure chamber 33 through another scavenging passage 23a, and its pressure operates to the upper side of a diaphragm 31. Furthermore, when the pressure in the crankcase 5 is increased at the same time that the pressure in a combustion chamber 9 is reduced, the force operating to the diaphragm 31 at the pressure chamber 33 side overcomes the force of a spring 29, and presses a scavenging valve 21 to the combustion chamber 9 side and opens it. As a result, the mixture gas flows in from the scavenging port 22, and scavenges the inside of the cylinder 1.
