Filed: 1980-03-12
Abstract: PURPOSE: To form an indefectible penetration bead without oxidation of the weld base metal, by using a grooved graphite plate as the backing material and by flowing inert gas, when thick plates of copper or copper alloy are welded to each other.  
     CONSTITUTION: When thick plates 1 and 2 of copper or copper alloy are welded to each other, a V groove is formed on weld end faces, and root end faces are matched to each other and are fixed. Then, the air hole of graphite backing material 3 is matched to the gap between roots of welding base metals, and further, the groove of device 4 which flows inert gas is fixed to the air hole of backing material 3. Before welding, inert gas such as Ar is flowed into the groove of device 4 and is caused to reach the groove faces of welding base metals 1 and 2 through the air hole of backing material 3. At this time, welding torch 6 is driven to start welding. Since gaseous Ar covers the whole of the groove, the groove part is prevented from being  oxidized, and indefectible penetration bead 7 is formed.

Abstract: PURPOSE:To reduce energy consumption in parallel operation of a plurality of feed water pumps, by controlling the flow rate by attaching an inverter to a motor for only one pump, and feeding current to other pumps directly from a power source, thereby stopping operation of the pumps or operating them under most efficient conditions. CONSTITUTION:When a switch S is turned ON, an electromagnetic switch 1C is energized and contacts 1C1, 1C2 are closed, which causes energization of an electromagnetic switch 2C, closing of a contact 2C1 and starting of an induction motor M1 and hence a pump P1. Here, output frequency of an inverter 2 is controlled by an output signal of a pressure sensor 3 such that pressure in a feed water pipe 4 is kept constant. When the flow rate of water is increased to Q.1a, a contact Q1 of a flow-rate relay 5 is closed and a contact 3c is energized, which causes closing of contacts 3C1, 3C3, 3C4, 3C5 and opening of a contact 3C2, so that a motor M1 is operated at a full speed by a power source. On the other hand, when the flow rate reaches Q2a, a motor M2 is operated at a speed controlled by the inverter 2, whereas the motor M2 is operated at a full speed when the flow rate is Q3a.

Title: Device for detecting presence of surface or boundary surface
Inventor: ANDORIYUU BII HARISON
IPC: G01B11/00
Filed: 1987-02-12
Abstract: PURPOSE: To accurately measure the top position of recessed surface of a contact lens under production by providing an irradiating device irradiating a parallel beam of optical radioactive beam along a sensitive axis passing a sensitive area, an optical radioactive beam detecting device, and a blade-shaped device disposed between these both devices. CONSTITUTION: A tool slide 23 is moved in the direction of an axis A toward an arbor 11, and an output from a photodiode 15 is monitored so that an intensity of an incident radioactive beam 16 can be recorded. When an external end area of a contact lens blank is adjacent to or aligned with the beam 16, the beam 16 is deflected by a surface diffraction effect so as to increase the intensity of an incident beam injected into the photo diode 15, and thus an output is developed from the photo diode 15 so as to show the presence of a surface. In this case, because a variation in the intensity of beam injected into the photo diode 15 becomes a clear symmetrical peak, an accurate top position is determined by a tool as to whether the average position of two equal intensity points is on either side.

Title: Coating method
Inventor: SHIRAKI YOSHITSUGU
IPC: G03C1/74
Filed: 1985-02-19
Abstract: PURPOSE:To evade troubles in coating at a web seam part by forming a bead so that the gap between the front edge of a die and a web is wider in the breadthwise direction at both end parts than at the center part. CONSTITUTION:Both ends of the bead 4 while degenerating toward the center with a shrinkage force based upon the surface tension of coating liquid expands toward both ends owing to wetting to the web 3 or a die surface in a slide hopper method. Further, the coating liquid stuck on the web at the bead part is to scatter with the centrifugal force based upon the rotation of a coating roller 2, but expands the both ends of the beam toward both ends because of resistance against the side wall of the die arranged opposite. Both ends of the beads are stable because the shrinkage force and expansion force are balanced. When the cumulation of a force in the bead breadthwise direction is remarkable in fast coating and/or wide-width web coating, slanting front edges 12 and 12' are provided to increase the storage capacity of both-end bead parts, thereby reducing troubles in coating at a seam part.
