Title: Device for removing dross in snout for continuous molten metal plating
Inventor: ASAHI ICHIRO
IPC: C23C2/00
Filed: 1988-06-29
Abstract: PURPOSE:To remove dross in a snout without interrupting plating operation by dividing a snout in a continuous plating apparatus into the upper part and the lower part and providing a trough inside the lower snout to scoop up dross floating on the plating-bath surface and collect it. CONSTITUTION:In a continuous plating apparatus, a snout 4 is divided into an upper snout 6 in which one end is connected to a reducing annealing furnace and a lower snout 7 in which one end is immersed in the plating bath 2 surface. The lower snout 7 is airtightly connected to the upper snout 6 in a manner capable of moving up and down by means of a flexible duct 8. A trough 11 is provided inside the lower snout 7 and the lower snout 7 is moved up and down, by which dross 3 on the plating bath 2 surface in the snout 4 is scooped up and collected. The trough 11 is allowed to communicate with a dross discharge pipe 9 provided through the wall of the lower snout 7, through which the dross 3 is discharged out of the snout 4. Further, the other end of the dross discharge pipe 9 is opened in the part under the plating bath 2 surface, by which infiltration of air atmosphere, etc., outside the snout 4 into the reducing atmosphere in the snout 4 can be prevented.

Title: Hydraulic device
Inventor: TAGUCHI SEIJI
IPC: F15B11/17
Filed: 1983-08-31
Abstract: PURPOSE:To reduce the power loss and make a device compact by setting a pilot room for unloading in a pressure compensating valve, and connecting the pilot room for unloading to a hydraulic pump/a tank for pilot, through a changeover valve. CONSTITUTION:In a pressure compensating valve 8, a pilot room 48 for unloading is set, and this pilot room 48 for unloading and a hydraulic pump 4/a tank for pilot are interlocked with each other through a changeover valve 56. In this way, the power loss can be reduced, as the fluid in an exhaust line can be unloaded under a low pressure and less engine torque is required when the engine is started. Moreover, the device can be made compact because the fluid in the exhaust line is unloaded through the unload line of the pressure compensating valve 8.

Abstract: PURPOSE:To make the convergence of an engine speed to the desired value performable so speedily, by operating an exhaust valve at a time when a difference between the engine speed and the desired speed is more than the specified value during shifting up. CONSTITUTION:When a select lever 7 is operated by a driving range, for example, a car is driven at second, if a driver operates an accelerator pedal 11, an MPU 9a judges of whether a transmission 6 changes the speed gear of shift-up or not, and when YES judgment is the case, successively it finds an engine speed Ne from output of a speed sensor 10, storing it in a random access memory 9a. And, a revolving speed Ni of an input shaft 6a is found out of a speed sensor 8a, storing it in the RAM 9a. And, a difference DELTAN between both speeds Ne and Ni is larger than the setting value, and when a difference DELTANe between the engine speed Ne and the desired speed Net is judged to be larger than the setting value beta, a solenoid valve 17 is controlled, closing an exhaust valve 13, thus engine motion is made to be checked.

Abstract: PURPOSE:To minimize the radial position shift of a magnetic head due to a thermal change, oscillation, etc., by forming the folded part of a flexible structure support part in a U-shape almost in parallel to the surface where it is joined with a floating slider, and installing a rigid structure support pressing part nearly in parallel to the floating slider. CONSTITUTION:The rigid structure support pressing part 10 is constituted in a horizontal shape by using a stainless steel plate, etc., and bending both breadthwise side to have rigidity. The flexible structure support part 11 is separated along a groove 15 into a surface 13 foined with the slider 2 and a surface 13 joined with the pressing part 10, and folded in the U-shape 16 from the surface 13 to make the folded parts nearly parallel to the surface 13, and a dowel is formed on the joint surface 13 so that the pressing part 10 presses the slider 2 at one point. The pressing part 10 is therefore arranged nearly in parallel to the joint surface 13 of the support part 11 because of the U-shape 16. Consequently, the off-track extent is reduced even if a head fitting part 5 is displaced upward or downward.

Abstract: PURPOSE:To prevent the variations of the state of adhesion by a method wherein a grid is provided between a target and a substrate, and the electrons flying to the substrate are absorbed by the grid, thereby suppressing the temperature rise of the substrate. CONSTITUTION:A grid 3 is arranged between a Ta target 1 and a substrate 2 located in a vacuum chamber. The grid is formed by reticulately knitting an Al wire of 500mum phi at the pitch of 5mm. After the vacuum chamber is evacuated to 10<-7>Torr, the chamber 4 is set at 1Torr or thereabout by feeding Ar gas, the Ar gas is ionized in the electric field using a power source 8, and the target 1 is sputtered by the electrons generated by said ionization to deposit on the substrate 2. At this time, the electrons having considerable kinetic energy are flown in the direction of the substrate, but as the electrons are absorbed by the grid 3, if the grid is maintained in the positive potential or equipotential with the substrate 2, the temperature rise of the substrate 2 can be suppressed, the temperature of the substrate cam be maintained at 100 deg.C or thereabout, and the variations in adhesion of the substrate can also be prevented. The density of electrons formed by ionization is made higher in the vicinity of the target 1 by magnetic poles 9 and 10, and they perform the function for improvement in the sputtering effect.

Abstract: PURPOSE:To secure a rule of thumb for finding such a spot that is hard to eliminate a sheet of jammed paper thoroughly by installing a counting means which counts detection frequency at each spot detected when a paper jammed state is detected at time of a release command of a jam mode. CONSTITUTION:When a sheet being fed out of paper cassettes 71, 72 has elapsed as long as the specified time required to range from paper feed rollers 711, 721 to a timing roller 73, it means that a jam has occurred, so that a jam 1 counter is made into one increment on the condition that a normally opened switch SW4 of a sub-door 4 is turned off. When an on-edge of a sensor PS2 is detected, it means that the jam has occurred in a sensitized drum part, a jam 2 counter is made into one increment. When a sheet to be fed to a transfer part from the timing roller 73 has finished its ample value for leading to a discharge roller pair 73, a jam 3 counter is made into one increment. Thus, a jam detecting process is executed.
