Title: Electric wire covering method and apparatus utilizing vertical type cooling water tank
Inventor: OZAWA ICHIRO
IPC: H01B13/24
Filed: 1994-08-04
Abstract: PURPOSE:To lower the driving cost by penetrating a covered electric wire which is covered from a through hole at the lower end of a seal cylinder to the open part by hot dip coating method, cooling the electric wire, and jetting compressed air upward from a through hole of a cooling water tank. CONSTITUTION:A covered electric wire 7 at high temperature immediate after hot dip coating process is introduced to a cooling water tank 2B through a through hole 2X of a second nozzle 2M installed in the lower end part of a seal cylinder 2A positioned under the cooling water tank 2B. The electric wire 7 at high temperature introduced into the water tank 2B is cooled by water in the water pole 18 and the temperature becomes low and the electric wire 7 is led out of the water tank 2B while the covering being fixed. Attributed to the pressure, compressed air P in the cylinder 2A rushes in a communication part 2Z of a first nozzle 2K from a space between a seal cylinder side open part 2V of the nozzle 2K and the wire 7 and jets to the water tank 2B from the space of a water tank side open part 2V and the wire 7. Strong upward air current generated in the open part 2V and downward water current which are flowing out to the communication part 2Z from the same open part 2V come into collision against each other, resulting in air-tight state can be maintained stably.

Filed: 1984-09-05
Abstract: PURPOSE:To improve magnetic attractive force of a chuck without forming it in a large size, by parallelly providing the first and second recessed groove to a surface opposed to the base member of a surface plate and arranging in the recessed groove respectively a permanent magnet opposing its magnetic pole surface over the whole range of wall surfaces of the recessed groove.

While the magnet 18 is integrally moved by controlling the knob 26, and if the magnets 16 and 18 are lined in an equal magnetic pole, the upper surface of the surface plate 12 is placed in a magnetized condition because a magnetic zone 12b is magnetized to polarity of an S or N pole corresponding to each magnetic arrangement, and a magnetic material, if it is placed on the surface plate, is guided to the magnetic zone 12b from the magnets 16, 18 further attractively mounted to the surface plate 12 by magnetic force in accordance with a quantity of magnetic flux via the magnetic material. Here a chuck, in which a magnetic pole area is increased because each magnetic zone 12a is brought into contact by a side piece part 16a, 18a of the permanent magnet in addition to its top piece part 16b and 18b, enables attractive force of the chuck to be increased without forming it in a large size.

Abstract: PROBLEM TO BE SOLVED: To realize a condensed oxide film which is restrained from forming a steeply part, induced by the stepped part of a ground layer. SOLUTION: A first plasma oxide film 15 is provided on the entire surface of a wiring layer 13 provided with an opening 13a or all the stepped surface of a wafer 11, using SiH4 (silane) gas and N2 O gas. Then, the reaction products produced by thermally reacting SiH4 and H2 O2 (hydrogen peroxide) with each other are condensed on the entire surface of the first plasma oxide film 15, to form a lower oxide film 17 at a temperature of 40 deg.C. By this setup, a steeply stepped surface of a ground layer is turned into a gently stepped surface. Then, reaction products produced by thermally reacting SiH4 and H2 O2 (hydrogen peroxide) with each other are condensed at the entire surface of the lower oxide film 17 for the formation of a condensed oxide film 19, under such conditions that a temperature and a pressure are set at 0 deg.C and 2.0Torr respectively.  Thereafter, a thermal treatment is carried out for fifteen minutes in a nitrogen atmosphere at a temperature of 400 deg.C. As a result, the condensed oxide film 19 shrinks, and the surface of the condensed oxide film 19 on the ground stepped surface or the opening 13a becomes smooth on account of the effects of the smooth surface in the lower oxide film.

Abstract: PROBLEM TO BE SOLVED: To control steering quantity according to the travel state of two-front- axle vehicle. SOLUTION: Interlocked with steering operation of a steering wheel 1, a front-front wheels 3 are steered by front-front axle steering mechanism 4. Independently of the front-front axle steering mechanism 4, a power cylinder 7 is driven to steer front-rear wheels 5 by front-rear axle steering mechanism 6. The steering angle of the steering wheel 1 is detected by a steering angle sensor, and the yaw rate and lateral deviation of a vehicle are detected by a travel state detecting means. According to the detection output of the steering angle sensor, a control device 9 steers the front-rear wheels 5 in the same direction as the front-front wheels 3 and controls the operation of a power cylinder 7 with the steering quantity with the yaw rate and lateral deviation added thereto.  The steering quantity is therefore controlled according to the travel state of a vehicle so as to suitably improve the steering characteristic of the vehicle.

Abstract: PROBLEM TO BE SOLVED: To greatly reduce the vibration force for inducing the primary bend mode of a rotor, by performing dynamic correction on the correction surface of both edges in a first balance correction, and performing correction on a correction surface that differs from the first balance correction surface. SOLUTION: After dynamic balance correction, the vector sum of unbalance remaining at both edges of a core 18 is calculated, an area (in this case, an area between both end faces of the core 18 or the central part of the core 18) on the outer-periphery surface of the core 18 that differs from both edge parts of the core 18 where dynamic balance correction is made is cut by a cutter when the vector sum is equal to or more than a specific value, and static balance correction is made, thus making correction to a specific value or less.
