Title: Position control device of pressure welding roll
Inventor: IGAWA HARUO
IPC: B41J13/02
Filed: 1984-07-20
Abstract: PURPOSE:To improve the reliability, and also to execute quickly a printing operation by controlling a pressure welding position by using a rotational position detector for detecting an actual position of a pressure welding roll. CONSTITUTION:A control part 7 stops driving of a DC motor by an input signal of a pressure welding detector 6 detecting a fact that a pressure welding roll 2 reaches a pressure welding position, detects a position deviation to a target stop position by inputting a signal of the rotational position detector 9, and feeds it back to a motor 5. In this case, an output of the rotational position detector 9 is set in advance so as to become ''0''V at a target pressure welding position. By said operation, it is corrected by a signal of the rotational position detector 9 that the pressure welding roll 2 comes to slip out of the pressure welding position by some external force. Also, by said operation, it is unnecessary to utilize a statical friction of the motor 5, therefore, a gear ratio of a gear box 4 can be made small, and the time of the pressure welding operation can be shortened.

Abstract: PURPOSE:To prevent a needle-sticking accident when a cap is fitted on an injection needle by forming a flange to the body of the cap. CONSTITUTION:In the opening part of a bottomed cap body for covering an injection needle 2 in which the injection needle 2 fitted to the end of an injector 1 is insertedly fitted, a flange for restraining the probability of insertion of the injection needle 2 toward the outside of the opening is formed.

Abstract: PURPOSE:To prevent the production of any punch-pressed chip at the time of being subjected to a punching-out and forming process by mutually combining the mutual intersecting points of wire rods forming a net in a molten condition. CONSTITUTION:A positive electrode current collector body 2 is manufactured by continuously feeding each hoop member of a stainless steel consisting of materials such as SUS304, SUS316, etc., to a punching press machine and punching out a round shape from it to form it into the shape of a disk. This hoop member is subjected to anneal treatment at the temperature of an extent from 1,000 to 1,200 degrees Centigrade and as a result, the mutual intersecting points 2b of respective wire rods 2a forming the net are mutually combines in one united body in a molten condition. Namely, the portion of the intersecting points or the neighboring area, even in the case where it has been cut off by means of the press, is prevented from its exfoliation for maintenance of its combined condition so as not to produce any punch-pressed chip because the mutual intersecting points of the wire rods forming the net have been mutually combined in a molten condition.

Filed: 1981-09-25
Abstract: PURPOSE:To obtain an easy-to-use programmable controller which meets various demands by permitting a user to set the conditions of what kind of abnormal state is detected and of what control state output is inhibited. CONSTITUTION:When a temperature fault flag F2 is set, an output inhibition flag F0 is set and a battery fault flag F1 is also set; when an external input signal 11 is turned on, the output inhibition flag F0 is set. Once the output inhibition flag 0 is set, output update operation is not performed and all external output signals from an output circuit 3 are turned off. Whether each instruction read out of a user program memory 1 successively is an output instructin for updating the output data of an input and output memory 4 or not is judged from its instruction code to make a normal output instruction ineffective, so the output data of the input and output memory 4 are never rewritten.
