Title: Highly active stepwise reactor process
Inventor: TILSTON MICHAEL WILLIAM
IPC: C08F4/658
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a polyblend in situ. SOLUTION: Ethylene and at least one kind of α-olefin comonomer containing 3-8 carbon atoms are brought into contact with a transition metal base catalyst system in vapor phase under polymerization condition in a pair of fluidized bed reactors connected in series. In the above process, the 1st reactor is operated at the dew point of the comonomer mixture or a temperature higher than the dew point by <=5 deg.C. The produced mixture of the ethylene copolymer matrix and the active catalyst is transferred to the 2nd reactor and reacted absolutely without supplying additional catalyst. The amount of the α-olefin is present at a ratio of about 0.01-0.4mol per 1mol of ethylene in a reactor for producing a copolymer having low melt-index and about 0.005-0.6 per 1mol of ethylene in a reactor for producing a copolymer having high melt-index.

Abstract: PURPOSE: To reduce resistance of an interface between a transition metal film buried in a connection hole and an aluminum alloy wiring and hence reduce a disconnection failure of a wiring by providing a barrier layer between the transition metal film and the aluminum alloy wiring. CONSTITUTION: A semiconductor integrated circuit device includes a first wiring 52 formed on a semiconductor substrate 20, and an interlayer insulating film 53 having an opening (connection hole) through which part of the first wiring 52 is exposed and formed on the first wiring 52. It further includes a transition metal film 54 formed over the connection hole 53D in the interlayer insulating film 53 and an aluminum alloy wiring 55B containing an additive Si formed on the transition metal film 54 and the interlayer insulating film 53. Particularly, a barrier layer (transition metal silicide film) 55A is provided between the transition metal film 54 and the aluminum alloy wiring 55B.  Hereby, the transition metal silicide film 55A can connect, even if the aluminum alloy wiring 55B is cut down owing to a migration phenomenon for example, the aluminum alloy wirings 55B putting the cut part therebetween, and can hence reduce a disconnection failure of a wiring.

Abstract: PURPOSE: To invariably maintain the travelling attitude of a car constant by a mechanical detection in cars used for work such as cleaning and painting inside large diameter pipes including dooling water intake pipes in a thermal power generation plant.  
     CONSTITUTION: When front wheels 3 and 3' deviate to the left from the imaginary path line in a pipe body 19 as shown by the arrow 20, the body 2 inclines to the right, causing a pendulum 15 to push a spool of a servo-valve 13 to the right. Consequently, a port P 2  of the servo-valve is communicated to a pressure oil feed port P 0  so that the connection point 21 between a power cylinder 10 and a pitman arm 9 moves to the right by a distance equal to the movement of a spool 14. As a result, the arm 9 thrns to the left on the fulcrum 7 to shift a tie rod 6 to the left. Thus, knuckle arms 4 and 4' rotate on the shafts 5 and 5' matching the steering angle of the arm 9 to turn the front wheels 3 and 3' back to the imaginary line.

IPC: F01N3/029
Filed: 1994-04-01
Abstract: PURPOSE:To independently optimum-control normal fuel injection in the compression stroke of an internal combustion engine and fuel injection in the expansion stroke for regenerating a filter with a catalyst. CONSTITUTION:A plunger 26 has a long stroke, and normal fuel is injected into a cylinder 41 of an engine which is at the end of the compression stroke by pressurization of a fuel in a pump chamber 27a during the time from when an intake hole 30 is closed by rising until it is communicated with a communicating hole 28. When the plunger is further raised, the intake hole 30 is again closed to pressurize the pump chamber, and a fuel is again injected into the cylinder 41 of the engine which is in the course of the expansion stroke until a communicating hole 29 is communicated with the intake hole 30. Added fuel is burnt in the gas to heat a filter with a catalyst in an exhaust pipeline, so that the carried catalyst is activated. After that, added injected fuel in the expansion stroke is oxidized by the catalyst, and particulates accumulated on the filter is heated by heat of the reaction and burnt to regenerate the filter.

Title: Electronic component mounting apparatus
IPC: B23P21/00
Filed: 1992-03-23
Abstract: PURPOSE:To eliminate the missing of components and realize unmanned operation for a long time by directing in such a manner that a component is supplied from another component feeder having the same identity of a component by retrieving a memory means by means of a directing means when the missing of a component from a component feeder is detected. CONSTITUTION:A component mounting apparatus is made up of a plurality of component supply feeders 3 that are arranged facing a number of mounting pins 2 attached to the circumference of a component carrier disk 1. In such a component mounting apparatus, a component missing detector 5 is disposed for each feeder 3. When any one of the detectors 5 detects the missing of a component, the identity of a component which has run out is read by retrieving from a component feeder storage area, and a value which is produced by subtracting 1 from the number of the depleted feeder is set as a feeder retrieve number. A decision is then made as to whether or not the identity of the component associated with this feeder retrieve number is coincident with the identity of the depleted component. When these identities are coincident with each other, a feeder which is in a good state is retrieved, and a current feeder number is updated to the number of the feeder in the good state because of the coincidence of the identities of the components, thereby continuing the supply of components.

Abstract: PURPOSE:To prevent a magnetic tape medium from slackening off during its transportation by inserting a stopper for preventing the slackening of the magnetic tape medium during the transportation into the magnetic tape medium to be in contact with a front surface of the magnetic tape after completing the take-up in accordance with an unloading instruction. CONSTITUTION:A control part 2, which received with unloading instruction via a control signal 10 from a host device, instructs a magnetic tape driving part 3 via a control signal 11 to execute its operation. The driving part 3, which received the execution instruction, starts taking up the magnetic tape medium 20, waiting for its completion. After acknowledging the completion of the take-up, the driving part 3 stops the magnetic tape medium 20, reporting the control part 2 via a control signal 13. The control part 2, which receives the advice of the take-up completion via the control signal 13, shafts up a stopper driving part 4 via a control signal 12. The driving part 4 is hence started up to bring the stopper 22 into contact with the front surface of the magnetic tape medium 20, operating a lever 23 for the purpose of inserting the stopper into between front and back reels to complete the operation. By this method, the slackening of the magnetic tape medium 20 during the transportation can thus be prevented.
