Title: Carrier-driving device for serial printer
Inventor: NARUSHIMA TSUGIO
IPC: B41J19/20
Filed: 1985-05-09
Abstract: PURPOSE:To automatically provide a spring material with a tensile strength to cope with a stretch of the spring material and to improve its endurance and to prevent a positional deviation of a carrier by making a supporting member to automatically provide the spring material with an appropriate tensile strength to cope with the force of a spring correspondingly to a stretch of the spring material, and by maintaining the supporting member to be held by a retainer in static condition. CONSTITUTION:Regardless of a stretch of a belt 7 due to a prolonged use, the belt 7 is automatically provided with an appropriate tensile strength by pivoting of a supporting member 10 by the force of a spring 14 to be in a balance with the force of the spring 14. At this time, a retainer 15 deflects a spring 16 and withdraws; and corresponding to an extent of pivoting of the supporting member 10, the supporting member 10 is maintained in a static condition by meshing one of teeth 18 with one of notches 19. Under the above condition, a reciprocating movement of a carrier 1 by normal or reversed rotation of a motor 8 does not result in an extension or shrinkage of the belt 7 because of a pivoting of the supporting member 10. Therefore, only if the step count to drive the motor 8 is set to move the carrier 1, the position of the carrier 1 never changes whether it is on a forwarding trip or on a returning trip.

Title: Automatic arc welding device
Inventor: NAKAMURA UHACHIROU
IPC: B23K9/028
Filed: 1983-06-03
Abstract: PURPOSE:To prevent interwinding of a welding cable, etc., and efficiently perform continuous circumferential welding, by controlling the torch angle through the combination of two axes of rotation intersecting each other with right angles and performing the circumferential welding. CONSTITUTION:A welding torch 1 is installed to the intersecting point of two axes of rotation beta and gamma. When the axes of rotation beta and gamma are formed in such a way that they interset each other at right angles in a horizontal plane and the welding torch 1 is installed to the intersecting point so that the axis of the torch 1 intersects one of the two axes at right angles, rotating directions of both axes beta and gamma are reversed whenever the welding torch 1 makes a half turn around a member 3 to be welded. Therefore, a welding cable 4 does not interwind itself around the welding device even though the torch 1 makes several turns around the member 3, and thus, continuous welding is made possible. As a result, the welding efficiency is improved and the welding quality can be stabilized.

Title: Method for detecting fault of semiconductor switching element of pulsed power supply
Inventor: TAKADOYA MASAHIRO
IPC: H03K17/73
Filed: 1990-04-16
Abstract: PURPOSE:To obtain the method for detecting a fault of a semiconductor switching element for a small pulse power supply by providing a comparator comparing the current of a current detector measuring a current flowing to a snubber capacitor at the time of charging with a current of a current reference generator supplying a reference current being a normal state current. CONSTITUTION:A sample and hold circuit 13 holds a peak value i1P of a current i1 flowing to a snubber capacitor 7 and since the relation of i1P=Iref exists, a comparator 15 discriminates the state to be normal. On the other hand, if one element in thyristors 6 is short-circuited, a peak i2P of a current i2 flowing to the capacitor 7 at that time expressed equations I is larger than the peak i1P. The peak current i2P held by the circuit 13 at the fault state is expressed in equation II. Since the current i2P is larger than the reference current Iref, the comparator 15 discriminates the occurrence of a short-circuit in any of the thyristors 6 thereby detecting the defective element. When two elements or over are faulty, since the current i2P is far larger, the fault is easily detected.

Title: Pulsing stream ejector
Inventor: VEKTERIS VLADAS
IPC: B01F5/00
Filed: 2013-06-03
Abstract: The invention belongs to the field of liquid saturation by oxygen and can be used in water preparation systems, where it is necessary to saturate cleaned water with oxygen before the process of disposal of waste (pollution). Moreover, it can be used in other branches of industry, for example: biotechnology and chemistry, where liquid saturation processes involving gas are present, when the debit of flow is variable. Working liquid flow under the influence of pressure is distributed into socket's cavity, where it starts spinning because of the holes in the socket's wall placed in the tangential direction and it is directed there to the bottom of the socket. Additional spinned working flow's turbulence is created because of the rises present at the bottom. Negative pressure forms at the irregular triangle's leaned pyramid's form, where are the rises of the narrowest plane at the hole which is connecting the socket with the ejecting surrounding's chamber. Through this socket ejected flow enters, which mixes with the working liquid. When the dynamic and static pressure proportion changes, spinned flow starts flowing towards the diffuser closing working flow' s ability to enter through the holes into the socket and this lessens static pressure, therefore again it opens liquid' s flow through the holes placed in tangential direction towards the cavity of the socket. Process can repeat from 1 to 20,0 kHz. It creates good conditions for the mixture of two environments and the placement of rises on the bottom of the socket, increasing from the center of the socket towards the wall in radial direction. This guarantees equal passing of the ejected environment into the cavity of the socket when the debit of the working liquid is variable.
