IPC: F23L15/02
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a regenerative burner type heating furnace which enables accurate control of discharging a combustion exhaust gas without increasing burden on an equipment surface. SOLUTION: Regenerative burners A and B are installed facing each other and the roles on the combustion side and the exhaust side are switched at a specified timing to discharge all exhaust gases to an exhaust path 30 from the regenerative burner B. Also provided are an exhaust gas flow regulating valve 34 provided in the exhaust path 30, an exhaust flow rate controller 50 to control the valve travel of the exhaust gas flow adjusting valve 34, an arithmetic device 40 for calculating a specified flow rate of an exhaust, a furnace pressure controller 47 for correction to compensate for a furnace pressure and an exhaust gas temperature controller 45 for correction to compensate for the temperature of an exhaust gas.  Thus, a correction value of the furnace pressure and a correction value of the temperature can be allowed for the set value of the flow rate of the exhaust thereby eliminating a flue direct connected to a heating furnace 2 and the control of the furnace pressure and the control of the temperature of the exhaust gas are accurately accomplished simply by opening or reducing the flow regulating valve 34.

Title: Sealer for heat-melted bag
Inventor: NAGAI TORAKICHI
IPC: B65B51/10
Filed: 1993-12-17
Abstract: PURPOSE:To make pressure-welding force at a heated part constant by dividing a portion of one of pressure bars oppositely provided into lengths of an attaching pitch of a sealer bar or less and elastically supporting each of the divided pressure bars individually. CONSTITUTION:An upper pressure bar 1 is made into a single long bar, while lower pressure bars 11, 12, 13 which have been divided into three are placed oppositely to the bar 1. The lower pressure bar 11 is designed to allow two sealer bars 7 to pass through, while the lower pressure bars 12, 13 are designed to be approximately equal to a pitch P or to a shorter length so that one sealer bar 7 can pass through. The upper pressure bar 1 and the lower pressure bars 11, 12, 13 are elastically supported via a spring 9 from a base 8. Thus insufficiency in pressure welding of heat-melted bags by a heating part can be prevented, and high working accuracy and assembling accuracy of the pressure bar or the sealer bar is not required, thereby making a sealer inexpensive.

Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain a speed measuring apparatus by which the speed of a moving body can be measured stably and precisely even under various conditons that the cause of a meauring error exists. SOLUTION: A central processing part 22 which constitutes this speed measuring apparatus 20 finds frequencies at upper second largest peaks on the basis of the distribution of a spectrum which is found when received data D(E1) based on a reflected echo Rw is FFT-computed. Out of them, the frequency whose value is larger is used as a target frequency corresponding the the speed (v) of a moving body, and the estimated speed (v0) of the moving body is found. Then, the found estimated speed (v0) is used as a new speed v (new), the new speed v (new) which is found in a previous processing operation is used as an old speed v (old). When the difference Δv between the new speed v (new) and the old speed v (old) is smaller than a prescribed value (vr), the new speed v (new) is adopted as the present speed (v) of the moving body.

IPC: G11B5/53
Filed: 1993-12-20
Abstract: PURPOSE:To perform recording and reproducing with a rotary transformer having a smaller number of channels than magnetic heads by reducing the number of channels of the rotary transformer in simple constitution. CONSTITUTION:A primary side coil 9 is wired in a groove in the lower surface of a primary side rotary transformer 5 to go half round on the side opposite to a primary side coil 8, and is passed through holes 9c and 9d to be led out to the upper surface. A terminal 9b is connected to a terminal 1b of a magnetic head 1, while a terminal 9a to a terminal 2a. The magnetic heads 1 and 2 are arranged on the outer periphery of the rotary drum on the sides opposite to each other by 180 degrees. The winding angle of a magnetic tape around the rotary drum is set to be <=180 degrees. Thus, a signal detected by the magnetic head 1 is transmitted via the primary side coil 8 and a secondary side coil 12 to a recording and reproducing circuit without being influenced by the head 2. The same is the case with the heads 2-4. In this constitution, since two concentric circular grooves having different radii can be formed opposite to each other, the primary side and secondary side coils can be constituted of two channels respectively, thus achieving miniaturization of the rotary transformer and the drum.
