Title: Device for preheating steel strip
Inventor: SHOJI MASAAKI
IPC: B23K20/00

Abstract: PROBLEM TO BE SOLVED: To reduce the space of a preheating furnace equipment and also to decrease the consumption unit of a fuel for heating furnaces by introducing combustion gas for the heating furnaces into a preheating chamber which is composed by imparting heat resistance to a spiral looper and surrounding its circumference with furnace walls. SOLUTION: The steel strip preheating device 9 is composed of the preheating chamber 10 in which the spiral looper 3 is incorporated, furnace shells 11 consisting of refractories and heat insulating materials with which the circumference of the spiral looper 3 is surrounded, table rollers 12 for transporting a steel strip S which are radically arranged, guide rollers 13 which are arranged in a concentric circular shape and with which the steel strip S is guided and pinch rollers 14 which are provided on the inlet and outlet sides of the spiral looper 3 and with which the amount of stock of the steel strip S is adjusted. All of the table rollers 12, guide rollers 13 and other mechanical parts or the like are composed of heat-resisting materials matching to the furnace temp. of the preheating chamber.  By taking the preset furnace temp. of the heating furnace 5 as 1300-1400 deg.C and by introducing the combustion gas into the preheating chamber 10, the furnace temp. of the preheating chamber is set to 900-1000 deg.C.

Title: Fluidic flowmeter
Inventor: OKABAYASHI MAKOTO
IPC: G01F1/20
Filed: 1986-12-02
Abstract: PURPOSE:To accurately measure a fine flow rate by constituting a flowmeter so that fluid is supplied to the measurement part intermittently in a short time. CONSTITUTION:A diaphragm and a valve seat 36 move toward an upstream pressure chamber 33 through the operation of a 1st spring 37 to close the valve seat 36 by a valve body 38, which is also moved by the valve seat 36 against the 2nd spring 39 to stop the supply of fluid to a 1st measurement part A. As the fluid flows out on the downstream side of the 1st measurement part A, the pressure in a downstream-side pressure chamber 35 becomes lower than that in an upstream-side pressure chamber 33 again and a low-differential- pressure operation type on-off valve D is opened and closed to supply the fluid to the 1st measurement part A intermittently in a short time. Therefore, the flow rate, even if fine and equal, appears to increase and is accurately measured.

Title: Electrophotographic copying device incorporating automatic adhesive sheet feeder
Inventor: EDOWAADO EFU MEIYAA
IPC: B65H3/20
Filed: 1987-11-17
Abstract: PURPOSE: To reduce the combination between paper sheets and apply the minimum force to the top sheet of a paper sheet bundle by providing a moving means for moving a paper sheet from the paper sheet bundle to a cartridge and sending to an entrance route.  
     CONSTITUTION: When the top sheet 19 of a paper sheet bundle is contacted with an adhesive strip 22, its front end edge 20 is contacted with the strip and adhered. Then, the arc shape surface for supporting the adhesive strip 22 is turned to the direction separating from the route in which the paper sheet is pulled out from the paper sheet bundle. At the same time, at least one part of a downward pressure is held. As this result, the front end edge of the paper sheet 19 is lifted up from a residual paper sheet bundle. The combination of the beam strength of a second paper sheet 19-2 staying under the top sheet 19-1 with the downward pressure applied to the paper sheet 19-2 maintains the paper sheet 19-2 horizontally during the front end edge of the top sheet 19-1 is lifted. After approaching to the front end edge of the paper sheet bundle, a barrier 28 with at least only the height of the paper sheet bundle is provided. The front end edge of the top sheet 19-1 is lifted on this barrier and the uper-side of the barrier can be pulled out in the direction opposite to the arrow mark 26.

IPC: G11B20/18
Filed: 1990-10-29
Abstract: PURPOSE: To verify that the first state has been changed to the second state by detecting the signal generated by a recording carrier while the recording carrier is being converted from the first state to the second state in accordance with binary write signals. CONSTITUTION: A modulated laser beam is generated in compliance with the state of a write signal WS genersted in an encoder/serial analyzer 42 by a laser/driver device 44. When the generated laser beam is at a low level, the optical disk 12 shows no change of state, and when the laser beam is at a high intensity, the reflecting surface of an optical disk 12 is brought into a state of no reflection. And a mirror 48 makes the laser beam to be penetrated and incident on the optical disk 12. The signal reflected from the optical. disk is directed to the second mirror 50 and detected by a detector/preamplifier 52 to be converted into an analog signal. Since this analog signal AVS represents the information of the optical disk 12, it is verified that the recording carrier has been converted from the first state to the second state in compliance with a binary information signal.

Title: Communication method and communication system
Inventor: KAWASHIMA NAOKI
IPC: G06F13/00
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a communication system capable of maintaining transmission and reception data when the waiting state of data transmission/reception is generated in a communication system. SOLUTION: At the time of detecting the congestion of an I/O bus in the middle of data transfer of each block toward a host computer 20, OLA(on-line adapter) 13 informs a host computer 20 of the presence of the transmission waiting state of data through the use of a strobe signal on an I/O interface 40. The host computer 20 receiving this prolongs a communication limiting time for the couontermeasure of a fault for a fixed time. When the congestion of the I/O bus 11 is eased, OLA 13 releases information and continues data transmission to the host computer 20. At the same time, the host computer 20 recovers the prolonged communication limiting time.
