Title: Production of tape-connection screw and apparatus
IPC: B65G47/08
Filed: 1992-01-20
Abstract: PURPOSE:To increase a production efficiency, by feeding screws to a tape having through holes for the screws so as to gradually and parallelly approach the tape from the front end of the screws toward the through holes in order to insert the screw front into the through hole, in the tape-connection screws for auto-screwing. CONSTITUTION:A screw head is fitted to the groove of a chuter 13 of a feeder 10 for screws and suspended to feed to a conveyor 20 by turn. On the other hand a tape 4 is fed from a tape feeder 60 on the tape-pushing belt 41 under the screws of the conveyor 20. The conveyor 20 is composed of a couple of screw conveyors 21, 22 which continuously transfer the screws one by one and pushes down them to the tape 4 side with a screw-pushing belt 40. Since the tape 4 is pressed from the downside by the pushing belt 41, the head of screw gradually approaches the tape 4 and it finally is inserted into the through hole of the tape 4 for the screws.

Abstract: PURPOSE:To obtain the coated film having uniform thickness without any pinholes by painting the coated film having uniform thickness under specified conditions, and further leveling said film by traveling a pig in forming the coated film with the pig forced feed method. CONSTITUTION:A front pig 2a and a rear pig 2b are inserted into a piping 1, and a paint 3 is interposed between both pigs. The pigs 2a and 2b are traveled by the liquid pressure from behind. In this case, the thickness of the coated film is regulated to 50% of the critical thickness wherein the paint is dripped to form a coated film 30. Subsequently the rear pig 2b at the preceding stage, for example, is used and traveled to level the coated film and to finish the surface of the coated film.

Title: Data transfer control equipment
Inventor: HITOMI MASAHIRO
IPC: G06F12/04
Filed: 1987-02-10
Abstract: PURPOSE:To unconditionally transfer a data of plural bytes, and to transfer a data at a high speed by providing a data transfer controller constituted of an interruption control mechanism, a violation correcting mechanism and a correction processing mechanism, etc. CONSTITUTION:A data transfer controller 4 is provided with an interruption control mechanism 4-1 for executing an interruption when a violation request of a plural byte transfer is executed from an odd memory address, a violation correcting mechanism 4-2 for executing a transfer of one byte by an interruption, and a correction processing mechanism 4-3. In such a state, when it is detected by the mechanism 4-1 that a plural byte transfer request is an odd address, an interruption is generated, and by receiving this interruption, the mechanism 4-2 executes a one byte transfer. Subsequently, after the one byte transfer is executed, when the number of data bytes of the plural type transfer is large, the mechanism 4-3 executes a carriage return and continues a regular processing. Also, if the number of data bytes is small, said mechanism continues the one byte transfer, and executes the regular processing in case of a transfer request from an even address. In such a way, a data transfer can be executed at a high speed.

Abstract: PURPOSE:To stabilize the operation of a pressure regulating valve by forming a valve chamber communicated with the primary side, in the rear surface of a main valve so as to effect a primary pressure as opposite forces which act the front and rear surfaces of the main valve, respectively in order to cancel out the primary pressure acting upon the main valve for reducing affection by variation in the primary pressure. CONSTITUTION:In a pressure regulating valve, the primary side 28 of a valve body 1 is isolated from the secondary side thereof by means of a main valve 6 having an upper surface to which a piston 3 is fixed. Further, a valve inner chamber 22 is formed in the piston 3. Meanwhile, a cylinder primary side chamber 23 and a cylinder secondary chamber 24 are formed, being vertically communicated with each other, outside of the piston 3. Since the valve chamber 22 in the rear surface of the main valve 6 is communicated with the primary side 28, the primary pressure is applied not only to the lower surface 6a of the main valve 6 but also the rear surface 6c thereof. That is, opposite forces act upon the lower surface 6a and the rear surface 6c of the main valve 6, respectively, so that they are canceled out together. As a result, the affection by variation in the primary pressure, with respect to the main valve 6, thereby it is possible to stably operate the pressure regulating valve.

Similarly, the waveform outputted by the ring counter output 34 rises up at the 33th clock and falls down at the 68th clock. The two waveforms 3Q, 33Q is ANDed. A 13 times counter 35 is connected to the Q output of first step flip flop of the ring counter and count the risie, and controls which one is to be outputted out of the pulses made by the ring counter output waveforms 3Q, 33Q. A 13 times counter is used for the counter 35 because the ring counter makes 13 times of round to make the succeeding horizontal scanning and phase coincide.

Title: Slopping prediction method in converter
Inventor: SAITOU KENJI
IPC: C21C5/32
Filed: 1980-03-11
Abstract: PURPOSE:To predict the coccurrence of slopping so that the refining condition is controlled to prevent its occurrence by detecting the uprizing slag level due to slag formation in the steel making refining process using a converter. CONSTITUTION:Gas blowing pipes 2, 2' having opening are embedded in the inner wall of a converter 1 at locations of allowable height for molten slag which is uprising with slag formation. The pipes are provided with a pressure detector 3 and are connected to a gas feeder 4. From the feeder 4, gas such as air, nitrogen, or argon is blown in to detect a pressure rise in the pipes 2, 2', when slag comes to the position of the pipes 2, 2' which is caused by slag formation occurring as oxygen blowing proceeds. This pressure rise is used to predict slopping that might follow. At this time, the operating condition such as the height of lance 8 or oxygen pressure is controlled, so that slopping is prevented from occurring.
