Title: Controlling method of taking-up of tension reel
Inventor: KAMOI HISASHI
IPC: B21C47/00
Filed: 1982-09-28
Abstract: PURPOSE:To prevent occurrence of defective products in a take-up reel by making taking-up tension small at first, then large, and thereafter controlling to normal tension when taking up a strip on a tension reel at the terminal of a continuous process line. CONSTITUTION:A cold rolled strip 11 came out from a skin pass mill 12 is taken up on tension reels 18, 19 through tension rolls 13, 14 and a pinch roll 16. In this case, the tension between the tension roll 14 and the tension reel 19 is detected by a tension roll 15. Number of revolutions of the driving motor 22 of the tension roll 18 is controlled by a controller 21 to make the taking-up tension <=5% of normal tension, and the strip is taken up up to third turn of section A. Then, taking-up tension up to 10-11th turn of section B is raised, and the strip is taken up up to 16-17th turn of section C at tension larger than normal tension by 15%. Thereafter, the strip is taken up at normal tension to the last.

IPC: G01N27/04
Filed: 1979-12-25
Abstract: PURPOSE: To prevent disconnection of a heater layer after burning and eliminate scattering of resistance value by forming the heater layer on one of two unburnt substrate material and by laminating the other substrate material with piercing holes in the positions corresponding to the terminal parts of material lead wires after connecting the lead wires with the heater layer.  
     CONSTITUTION: The heater layer 13 is formed on the ceramic raw sheet substrate 11a by using platinum paste or the like and the lead wires 14a, 14b and 14c are connected with the terminal part 13a and 13c of the layer. Next, the other substrate 11b is provided with piercing holes 12a, 12b and 12c corresponding to the terminal parts of the lead wires and then is laminated on the layer 13, with positioning being made correctly so that the tips of the lead wires 14a and 14c are positioned nearly at the centers of the terminal parts 13a and 13b. In this way, the tips 12d, 12e and 12f are positioned within the piercing holes 12a-12c of the substrate 11b. Then, electroconductive material is put into the piercing holes to ensure the connection. Thus, the disconnection and the like of the heater layer 13 is prevented and the yield of the substrate 11 is improved.

Title: Scum removing apparatus for sewage tank
Inventor: FURUMOTO HIROTADA
IPC: E03F5/22
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To prevent deposition of scum by arranging a water receiving section below an opening of a discharge pipe so as to be spaced away from the opening, and allowing a part of sewage drawn up by a pump to fall from the opening to the water receiving portion. SOLUTION: When sewage flows from a sewage inflow pipe 5 into a manhole 10 and the water level of the sewage reaches a pump activation level W1, a control device detects a signal from a float-type water gauge 22, to thereby activate an underwater pump 11. The sewage sucked from a suction port 11a of the pump 11 is squeeze-pumped to a conveying pipe 12 and discharged via an exhaust pipe 15 to the outside. The sewage flowing in the conveying pipe 12 is branched to a water diffusing mechanism A to be introduced to a discharge pipe 30, and then sprayed downward from an opening 31. The sewage collides on a water receiving section 37 and the spraying direction of the sewage is changed to the horizontal direction, whereby the sewage reaches an inner surface of the manhole 10 and the conveying pipe 12.  Further, scum present on the inner surface of the manhole 10 and a surface of the conveying pipe 12 is caught up in jet flow, and then sucked into the pump 11 and discharged by the same. Thus, deposition of scam can be prevented.

Abstract: PROBLEM TO BE SOLVED: To provide accurate network information even in case of a failure in renewing a cache file or if the latest information is not reflected on the cache file. SOLUTION: When a WWW server requests information regarding a network (S2001), a network management program checks whether the cache file is a new one (S2002), and gathers information newly (S2003) when a specific time is elapsed after the file is generated and saves it in the cache file (S2004). It is checked whether or not the cache file has the end tag of an HTML document (S2005) and when not, it is considered that the saving is a failure, thereby deleting the file (S2006).

Title: Air purifier
Inventor: OKADA AKIRA
IPC: F24F13/28
Filed: 1983-09-12
Abstract: PURPOSE:To substantially decrease the draft resistance of a filter and consequently contrive to increase the purified air flow per unit time by a method wherein the air is caused to be past through the filter being applied by centrifugal force. CONSTITUTION:A blast fan 8 and a filter mounting frame 9 are rotated by energizing a motor 7 and air is sucked through suction holes 4 into a main body case 1. The air flows downwards along the outside of a casing 13 as indicated with the arrows A so as to be sucked through an air vent 14 arranged on the bottom of the casing 13 into the filter mounting frame 9. Further, the air flows from the inside to the outside of the frame 9 as indicated with the arrows B by progressively passing through an electrostatic filter 11 and a deodorizing filter 12. In this case, because both the filters 11 and 12 rotate at high speed integrally with the filter mounting frame 9, the air flowed in both the filters 11 and 12 is applied large centrifugal force by both the filters 11 and 12. As a result, the air sucked in the filter mounting frame 9 is caused to pass through both the filters 11 and 12 under both actions due to the suction force developed by the blast fan 8 and to the centrifugal force given by both the filters 11 and 12.

Abstract: PURPOSE:To collect data from respective fire phenomena detecting parts by a receiving part with the same transmission format as that of a conventional fire alarm facility by equipping each fire sensor with a top address setting means and a related address setting means. CONSTITUTION:Addresses 2-4 are assigned to a multielement sensor B, and a heat detecting part, a smoke detecting part, and a gas detecting part are respectively made to correspond to the respective addresses 2-4. Further, addresses 6-8 are assigned to a multielement sensor D having only the heat detecting part and the gas detecting part, and while the heat detecting part and the gas detecting part are respectively made to correspond to the addresses 6 and 8, the address 7 is made into an empty state since no smoke detecting part exists in the sensor D. In this case, only the top address is set to the address setting means of a dip switch, a ROM, etc., provided for each multielement sensor, and the other two addresses are set by either software or a program. Thus, the receiving part can collect the data from the respective fire phenomena detecting parts with the same transmission format as that of the conventional fire alarm facility.

In this semiconductor device, a protecting diode is formed in semiconductor substrates 24 and 25 so that the current conducting direction is reverse with respect to the gate electrode interconnection 32a. The bottom part of the through hole 35 undergoes sputtering before the upper interconnection layer 36 is formed on the insulating layer 35 and the gate electrode interconnection 32a and the upper interconnection layer 36 are connected. When the potential of the gate electrode interconenction 32a is increased due to charge-up at the time of sputtering, the protecting diode is broken down, and carriers are guided to the semiconductor substrates 24 and 25. The protecting diode is formed by, e.g., a diffused layer 29 and the semiconductor substate 24.
