Patent JP-S55145949-A (JP)
Title: Conveyor
Inventor: KADOI HARUO
IPC: B65H29/58
Filed: 1979-04-26
Abstract: PURPOSE:To enable always stable conveyance and prevent overlap-conveyance and front end bending, by changing the protruded quantity of a stopper which comes into contact with the front end of copy paper, depending on the stacked quantity of the copy paper. CONSTITUTION:Copy paper 6 is stacked on an internal plate 2. The internal plate is lowered due to the weight of the paper. A lever 47 is pulled downward by a spring 48 as the lever is in contact with a stop member 49. At that time, the front end 41a of a stopper 41 is protruded from a front plate 5 because an L-shaped metal member 50 and the level 47 are free. The protruded quantity (h) of the stopper 41 can be adjusted in terms of the height of the stop member 49. Since two corners of the copy paper 6 are in contact with the front plate 5 and the central part of the paper is in contact with the stopper 41 and the resistive force of the front end of the paper is sufficient, perfect separation is effected and overlap-conveyance is prevented even if a paper feed roller 22 falls and resumes supplying the paper.

Title: Take-in device for paper sheet
Inventor: TSUKADA YASUO
IPC: G07D9/00
Filed: 1988-03-09
Abstract: PURPOSE:To reduce the size of a motor and to improve economy without disabling take-in by temporarily decreasing the rotation of a take-in roller shaft when a folded or crimped paper sheet is taken into the device. CONSTITUTION:When a folded or crimped bank bill P is taken in, it is not taken into the take-in section 9 regardless of rotation of take-in rollers 5, 5. It is because the bank bill P produces negative pressure in the take-in section 9 and increases torque of the take-in roller shaft 21, and when the load reaches to a transmission torque (T) slip occurs between the coupling members A28a and B28b in a detent mechanism 28 thus driving the roller shaft 21 through the rotary shaft 27 with torque (T') and reducing the rotation. When the rotation of an auxiliary shaft 30 decreases and matches to the rotation of a gear A31, the one-way clutch 31a of the gear A31 engages with the auxiliary shaft 30 to transmit the rotation of the gear A31 to the gear B33, and thereby the roller shafts 5, 5 take in the bank bill P with torque increased through reduction of rotation.

Title: Stirling engine
Inventor: INOTA KENICHI
IPC: F02G1/043
Filed: 1988-03-08
Abstract: PURPOSE:To reduce a loss caused by an inflow of fluid into bounce space by respectively providing a flow path communicating with a clearance of a displacer rod from gas spring space and a flow path, provided with a check valve, communicating with the bounce space from the clearance of the displacer rod. CONSTITUTION:When a displacer 30 is, for instance, lowered, because the volume of compression space 46 decreases while the volume of expansion spacer 54 increases, helium in the inside of the compression space 46 and a cooler 28 moves passing through a regenerator 29 and a heater 27 to the expansion space 54. Here following lifting of the displacer 30, two or more flow paths 38, 40 communicate through a clearance 39, thus when a pressure in gas spring space 37 is lower than a pressure in bounce space 41, the pressure is equalized by allowing the helium to flow into the former 37 from the latter 41. When the displacer 30 is lowered, a reverse flow of the helium in the gas spring space 37 to the bounce space 41 is prevented by a check value 50, thus an increase is eliminated of a friction loss or the like.
