Title: Method for controlling cooling of wire rod in hot-rolling
Inventor: ENDO MASASHI
IPC: B21B45/02
Filed: 1993-06-30
Abstract: PURPOSE:To shorten the length of a uncooled part with water at the tip part of a wire rod in a hot rolling. CONSTITUTION:After detecting the tip part of the wire rod with steel material detectors 6, 7 arranged at the upstream side of a cooling device 1 for wire rod 16, a cooling water change valve 2 is opened to spout the cooling water. At the fixed time before the tip pat of the wire rod reaches the cooling device 1, the cooling water change valve 2 is closed to stop the cooling water, and thereafter, the cooling of the wire rod 16 is started. By this method, regardless of the length of the rolling pitch, the condition of the cooling water supplying pipe before starting the cooling becomes almost constant and the time from opening of the cooling water change valve 2 to actual spouting of the cooling water from a cooling nozzle becomes also almost constant. Even if the rolling pitch is increased, the uncooled part with the water at the tip part of the wire rod is shortened and the yield is improved.

IPC: H01B13/016
Filed: 1995-06-05
Abstract: PURPOSE: To manufacture a foamed coaxial cable which is excellent in an electric characteristic and by which a transmission loss is particularly reduced by using polyolefine resin having a melt index prescribed quantity as an insulating layer, and sufficiently cooling and solidifying it in a long size land die. CONSTITUTION: A mixture of polyolefine having a melt index MI = 4.0 to 20g/10min and a nucleus formation agent to be supplied to a first extruder 4, is melted in the extruder 4. There, physical foaming agent is pressed in the extruder 4 through a pump 3, and is sufficiently mixed with a melting material. Afterward, the mixture in the extruder 4 moves to a second extruder 5. In the extruder 5, an extruding temperature is lowered more than the extruder 4, and is adjusted to a temperature slightly higher than a melting temperature of polyolefine resin. The mixture in the extruder 5 is extruded in a long size land die 6 directly connected to an extruder head, and foams simultaneously when it is press-fitted to the periphery of a preheated conductor 8 sent into through an axial part of the die 6. Afterward, an insulating layer is gradually cooled in the die 6, and the insulating layer is formed.

Title: Device for measuring quantity of suction air in internal combustion engine
Inventor: HOSOYA YASUHIKO
IPC: F02D41/34
Filed: 1978-12-26
Abstract: PURPOSE: To measure the quantity of suction air exactly by providing an air pressure feed port in the upper stream of the vortex generator bar in the suction air passage and by controlling the generation quantity of vortex.  
     CONSTITUTION: The air pressure feed port 9 by which air pressure can be applied to the suction air flow is opened in the upper stream of the vortex generator bar 2 in the suction air pipe 1, a pressure is applied to the suction air flow from the pressure feed port by the air pressure pump 7 through the air pipe 8 to control the quantity of produced vortex on purposely disturbing the air flow. Since the ultrasonic wave generated by the ultrasonic wave oscillator is modulated by the vortex produced by the vortex generator bar, the modulation signal is received by the ultrasonic wave receiver 5 to detect the quantity of suction air. In this way, a detection error of the air quantity can be reduced by making the difference between the vortex production in the normal state and that in the state, in which the valve is closed and no air flows, less.

Abstract: PROBLEM TO BE SOLVED: To easily retrieve related information by using past retrieval operation information extracted from an access history. SOLUTION: An access monitor 1 always monitors access to information by a user, and updates an access history data base 3 which is divided by users. At retrieval time, information in the access history database 3 is displayed on a screen by extracting information which is arranged and saved by using the access user and time as keys. For the rearrangement of the access history, the time intervals of records of the access history are checked and when there is an interval larger than a certain value, it is considered that operation is paused and the access history is sectioned to generate clusters. Documents included in the respective clusters are ordered according to the access frequencies and documents having higher access frequencies are considered to be valuable, and arranged and displayed on the screen.  Consequently, the know-how obtained by user's past operation can be utilized for information retrieval.
