Title: Chain
Inventor: KUBOTA MASAO
IPC: F16G13/06
Filed: 1992-07-21
Abstract: PURPOSE:To provide a chain with small frictional wear which is used in transmission and carriage. CONSTITUTION:A triple structure of a pin, a bush and a roller as shown in the conventional chain is eliminated, and the pin is directly engaged with the tooth surface of the sprocket, and the pin 2 is supported by roll bearings 72,82 mounted on a connecting link plate (inner side link plate 512 and outer side link plate 623), and the lubricant is sealed therein. Direct rolling contact is executed between the sprocket tooth surface and the pin tooth surface, and the rolling contact is also executed at the folding between the link plates, resulting in smaller frictional wear as a whole, and smaller losses in the power and slight extension to maintain high accuracy. A sliding bearing is also used in some designs.

Inventor: DOI YUZURU
IPC: A61B1/00
Filed: 1988-09-19
Abstract: PURPOSE:To always accurately measure a length by changing the direction of a length measuring part optionally with respect to the observation visual field of an endoscope by curving a tube in the diameter direction at the position a little near the base part of the tube from the second slit to connect the tube at the cut part in a manner freely rotatable around the axis of the tube. CONSTITUTION:A tube 1 is cut in the diameter direction thereof at the position a little near the base part of the tube in the vicinity of a constricted part 13. Connection pipes 16, 17 are bonded to the inner surface of the tube 1 on both sides of the cut part 15 and engaged with each other in a freely rotatable manner. By chamfering the end part 16a of the connection pipe 16 becoming the inside to widen the same, both connection pipes 16, 17 are connected in a freely rotatable manner so as not to be pulled out mutually. Therefore, the tube 1 is connected freely rotatable in the axial direction at the cut part 15 through the connection pipes 16, 17. The part on the side of the base part from the cut part 15 is rotated integrally along with an endoscope, and the direction of a T-shaped length measuring part 5 can be charged in the observation visual field of the endoscope.

Title: Method and device to carry flat printed matter
Inventor: COTE KEVIN LAUREN
IPC: B65H29/06
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To eliminate a speed difference between a surface of a cut drum and a tape system as an arm has a grabbing mechanism to grab a section to deliver a carrier unit and it rushes in a division where a carrier element is low to grab the front edge part of the section in accordance with rotational motion of the arm. SOLUTION: A continuous material web 1 intrudes into a nip between an anvil drum 3 and a cut drum 2. After side cutting, a section delivered from the nip between drum surfaces 9 runs into a carrier unit 10. The carrier unit 10 has a circulating element to cooperate as a flat tape 11 and a divided tape 12, and the tapes 11, 12 are circulated. A higher division 13 supports first and second sections, and length of the sections is larger than length of the high division 13. A drive device of a roller 16 and a drive device of a pair of the cut drums 2, 3 are connected to each other, and they are divided from a cut drum surface. Consequently, it is possible to eliminate a speed difference between the cut drums 2, 3 and the carrier unit 10.

Title: Delay circuit
Inventor: OKUHARA YASUFUMI
IPC: H03K5/13
Filed: 1985-10-21
Abstract: PURPOSE:To execute efficiently the operation of a sequential circuit by delaying an input signal applied when the sequential circuit is executing an instruction, until the execution of the instruction is completed, and thereafter, applying it to the sequential circuit and processing it. CONSTITUTION:When an input signal 9 is varied from high to low at the time t2, a differential signal is generated in an output 10' of a differentiating circuit 10 thereby, but since a sequential circuit 6 is executing an instruction, namely, a control signal 8 is low, a differential signal of the output 10' of the differentiating circuit 10 is inhibited by an inhibiting circuit 5, and a DFF holds the previous state. Also, at the time t3, the sequential circuit 6 completes the execution of the instruction, and the control signal 8 is varied from low to high. As a result, a differential signal is generated in an output 11' of a differentiating circuit 11, and it is applied to a T input 3 of the DFF 1. In such a case, since the input signal 9 is low, a Q output 4 of the DFF 1 is varied from high to low, and the sequential circuit 6 starts to execute an instruction corresponding to it, and varies the control signal 8 from high to low.

Title: Thermal printer
Inventor: YAMAKAWA KENJI
IPC: B65H1/06
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent heat-sensitive recording paper from curling and absorbing moisture in a paper feeding cassette, and attain smooth paper feeding. SOLUTION: A plurality of stacked color heat-sensitive recording paper sheets 15 are pressed by a pressure plate 22 with the surface of the recording paper facing upward. A paper presser 30 moves between a pressing position on the color heat-sensitive recording paper sheets 15 and a retreating position at a distance from the color heat-sensitive recording paper sheets 15. When paper feeding operation stops, the paper presser 30 is set to the pressing position to sandwich the stacked color heat-sensitive recording paper sheets 15 between the pressure plate 22 and it. The intervals between the color heat-sensitive recording paper sheets 15 are, therefor, brought into close contact with each other, thus it is possible to prevent the recording paper sheets from curling and absorbing moisture. The paper presser 30 moves toward the retreating position at the time of feeding paper.  During the paper feeding paper operation, frictional resistance between the color heat-sensitive recording paper sheets 15 is suppressed for smooth paper feeding.
