Title: Control system of printing head
Inventor: OKUHARA TETSUO
IPC: G06K15/08
Filed: 1983-04-22
Abstract: PURPOSE:To make it possible to efficiently position paper to the next printing position, in a serial printer, by detecting a false paper width by detecting a printing region while comparing the paper width with a present printing head position to operate a printing head. CONSTITUTION:An interface circuit 2 sends intake data to printing buffer 4 when said data is a printing code and simultaneously outputs a signal 10 to raise a counter 11. On the other hand, when it is a code for indicating printing start such as a new line, a next stage comparator circuit 14 is operated by a signal 6 to compare the content A of the counter 11 and the content B of a latch and, in the case of A>B, a gate 7 is opened by output 13 becoming real and the content A is taken in the latch 9. By repeating this operation, the content B of the latch 9 comes to a false paper width. This width B and the present position 30 of a printing head are compared by a microcomputer 31 and, only when it is judged that the position 30 is out of the paper, traction operation is used while, when it is judged that it is above the paper, only gap enlarging and re-adjusting operation is perfomed. By this method, positional determination can be efficiently performed.

Title: Oil seal
Inventor: WASHIDA AKIRA
IPC: F16J15/3244
Filed: 1981-05-12
Abstract: PURPOSE:To obtain high sealing performance even if produced by die setting by providing a number of annular concavities and convexities at an oil level angle side of a seal lip where many concavities and convexities are axially made contiguous to or in vicinity to a contiguous point of a seal angle side and an oil level angle side. CONSTITUTION:Inner periphery of a rubber 2 which was burnt and attached to a reinforced ring 1 forms a seal lip 3. At a seal angle side (A) of the seal lip 3, many axial concavities and convexities (D) are made contiguous to or incinity to a contiguous point (C). On the other hand, many annular concavities and convexities (E) are made at an oil level angle side (B). When an axis is rotated, the concavity-convexity (D) is bent to form a twisted viscous pump, but since there are many concavities and convexities (E) at the oil level angle side (B), flexibility of the contiguous point (C) and its vicinity becomes larger and the concavity- convexity (D) becomes easy to be bent. Also, high sealing performance is obtained by producing by die setting, without machining of the oil level angle side (B).

Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the stretched state of a bandsaw from being hindered by structuring a bandsaw tensioning device of a bandsaw tensioning weight suspended from one of the ends of a bandsaw tensioning lever, an ejection rod with the lower end supported on the other end of the bandsaw tensioning lever and the upper end engaged with a movable shaft and a vibration absorbing device interposed between the one ends of the tensioning weight and the tensioning level. SOLUTION: A bandsaw tensioning weight 5 is suspended on one of the ends of a bandsaw tensioning lver 4 installed in a freely rotatable manner, while the other end of the tensioning lever 4 is engaged with the lower end of an ejection rod 6 through a supporting shaft 6a or the like. The upper end of the ejection rod 6 is engaged with a bearing for a movable shaft 1a and an upper saw wheel 1 is rotated centered around a rotary shaft 1b to be urged in a direction in which the wheel 1 becomes separated from a lower saw wheel 2. A vibration absorbing device 7 reduces vertical vibration to be generated by the acceleration to the tensioning weight 5 by the vertical shaking of the tensioning lever 4 following the stretching of the bandsaw 3 and is interposed in a route between the end part of the tensioning lever 4 and the tensioning weight 5.  Thus it is possible to effectively prevent a vibration generated by the variation of a bandsaw tensioning force during the rotary operation of the bandsaw 3 from being transmitted to the tensioning weight 5, even when the vibration is generated in the tensioning lever 4 following the stretching of the bandsaw 3.
