Title: Burner
Inventor: KAMIYA KOSEN
IPC: F23D5/10
Filed: 1985-10-08
Abstract: PURPOSE:To reduce a generation of soot or carbon and make a stable condition of combustion in a burner with an amount of combustion air and an amount of fuel balanced by a method wherein an upper edge of an outer circumferential of combustion pan is kept at a horizontal level and an inner wall at a bottom surface is gradually downwardly inclined toward an injecting direction of a combustion flame. CONSTITUTION:A pre-combustion chamber 6 of a burner 10 is made such that a combustion chamber pan 18 of a box-like shape with its one side being opened is fixed to a lower part of a fixing plate 16 and an ignition cloth 19 is arranged at a bottom surface of the combustion chamber pan 18. An air adjusting valve 20 for adjusting combustion air is pivotally supported at an opening and an ignition heater 21 is fixed to a central part of the air adjusting valve 20. At a closed position of the air adjusting valve 20, an ignition cloth 19 is automatically ignited with this ignition heater 21. Since an inner wall part of a bottom surface 4 of the combustion pan 2 is inclined downwardly toward a combustion flame injection direction, a main fuel during drying operation is increased in its dropping volume directed toward the combustion flame injecting direction. Due to this arrangement, a large amount of combustion fuel and air are supplied at the combustion flame, a balance between the amount of combustion air and the amount of main fuel is kept well and the burner 10 is always kept in its stable combustion.

Title: Magnetic head and its manufacture
Inventor: IIMIN FAI
IPC: G11B5/31
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To write data tracks with a high line recording density. SOLUTION: A magnetic head has 1st and 2nd pole tip layers 26 and 30 which are separated from each other by a nonmagnetic gap layer 42. Both the pole tip layers 26 and 30 are made of high magnetic moment material. The left side walls 26A and 30A of the 1st and 2nd pole tip layers 26 and 30 are matched with each other in a vertical direction. In the same way, the right side walls 26A and 30A of the 1st and 2nd pole tip layers 26 and 30 are matched with each other in a vertical direction. With this constitution, a magnetic head which enables practically the reduction of a side fringe flux from one of the pole tip layers to the other and by which boundaries of tracks can be satisfactorily defined when data are written can be obtained.  As the pole tip layers 26 and 30 which are made of high magnetic moment material can provide high coercive forces, it is less probable that the pole tip layers 26 and 30 operate in magnetic saturation states. The magnetic head can be manufactured as a reverse-type head or a nonreverse-type head and can write data in a magnetic medium with a high saturation coercive force at a high data transfer speed.

Title: Waveguide for mounting in satellite
Inventor: MORIGUCHI TATSUJI
IPC: H01P3/12
Filed: 1989-08-31
Abstract: PURPOSE:To considerably freely lay out parts in a communication device by providing a heat pipe on the outside wall along the transmission line of a waveguide and approximately uniformly reducing the temperature of the waveguide to efficiently suppress the temperature rise of the communication device and the waveguide. CONSTITUTION:A waveguide 5 is connected to a communication equipment 12 placed on a satellite platform 7. Heat pipes 6 having a circular section are provided on the upper outside wall and the lower outside wall of the waveguide 5 in parallel with and closely to the signal transmission line. Since the waveguide 5 is provided with heat pipes 6, the heat generated by the communication device is dissipated not only through the placing face but also through the heat pipes of the waveguide 5. Consequently, the quantity of heat radiation is increased in comparison with heat radiation from only the placing face to suppress the temperature rise in the communication device 1. Though much heat is generated from a final amplifier provided apart from the placing face, the heat is dissipated to the outside from the nearby waveguide 5 through heat pipes 6.

Title: Current detection device
Inventor: KAMIKAWACHI TOSHIHIRO
IPC: G11C16/06
Filed: 1988-09-09
Abstract: PURPOSE:To read at high speed by making variable the on-resistance of a load transistor under the condition of reading. CONSTITUTION:When data change from '0' to '1' and a current starts to flow from a bit lien BL, the potential of the bit line BL is decreased, a node N1 turns to be a higher level to be determined by the ratio of the on-resistance of transistors (TR) Q1 and Q2 and turns on TR Q3 and Q4 for feedback. In this case, a voltage between the source gates of load TR Q5 is dropped and the on-resistance is increased. On the contrary, when the data change from '1' to '0' and the current stops flowing from the bit line BL, the potential of the line BL is increased, the node N1 turns to be a lower level to be deter mined by the on-resistance of the TR Q1 and Q2 and turns off the TR Q2 and Q4 for feedback. In this case, the source gate voltage of the TR Q5 is increased and the on-resistance is lowered. Consequently, the node N2 can be charged form the potential of the line BL to a current voltage terminal Vcc level within the short period of time. Thus, the high speed reading can be executed.
