Title: Radio wave interference suppressing method for antenna of vor navigation system
Inventor: KINOSHITA YUKIHIRO
IPC: G01S1/04
Filed: 1987-01-28
Abstract: PURPOSE:To suppress effectively radio wave interference from a VHF communication device antenna by changing connections between a couple of VOR antenna elements and a phase coupler and employing a connection which provides a smaller disturbing radio wave for VOR receiver input. CONSTITUTION:Connection cables 5 and 6 of the VOR antenna elements 1 and 2 are inserted to the phase coupler 3. Then a delay cable 4 is connected to the cable 6 and the antenna-induced voltage of the cable 5 is delayed by half wavelength and added to the other, so that the sum voltage is inputted to a VOR receiver. Then signal voltages V1 and V2 which has a phase difference of half wavelength are induced at the elements 1 and 2 with a VOR radio wave which is a horizontal polarized wave, and disturbing radio waves V3 and V4 from the VHF communication device antenna are also generated. Those induced voltages are inputted to the coupler 3 and the cable 4 puts the voltages V1 and V2 in phase and the voltages V3 and V4 opposite in phase. For the purpose, connections with the cables 5 and 6 are switched to employ the connection which provides a smaller disturbing wave between the voltages V3 and V4, thereby suppressing the interference between radio waves from the VHF antenna.

Title: Stencil printer and its ink dry preventing method
Inventor: KOBAYASHI KAZUYOSHI
IPC: B41L13/14
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To immediately print an image of uniform density as a whole even if a new stencil master is mounted on a plate cylinder and printed after a stencil printer is left to stand for a long period. SOLUTION: In a normal stencil printing mode for adhering ink to a printing sheet P and printing it, a stencil master 8 is wound on an outer periphery of a plate cylinder 1 with a thermoplastic resin film 21 disposed at an outside. At the time of an unprepared stencil winding mode, a controller 30 for holding an end 8a of the master 8 by a clamper 7 to rotate the cylinder 1 in an opposite direction to an arrow A so that the film 21 is wound inside to be brought into contact with the outer periphery of the plate 1 is provided. Thus, even if a stencil printer is left to stand for a long period, ink held in pores of the cylinder 1 is sealed by the film surface, and hence scarcely dried. Accordingly, a satisfactory image is obtained by sufficient ink amount from an initial time of restarting printing.

Filed: 1986-01-29
Abstract: PURPOSE:To improve the quality of a worked article and the grinding work efficiency by continuously or intermittently feeding a polishing material stick onto the working surface of a grindstone consisting of superabrasive grains in grinding work by an automatic feeding device and carrying out the dressing work without suspending the grinding work. CONSTITUTION:As for a grindstone 1 consisting of superabrasive grains, the cutting edge 3 of the superabrasive grain 2 is worn out through the grinding work or made dull by the welding of chips 4, and the abrasive grain projection quantity 5 is reduced, and clogging is easily generated, and the cutting performance is deteriorated. At this time, the polishing material stick is fed continuously or intermittently at a certain cutting-in speed through an automatic feeding device onto the working surface of the grindstone 1 consisting of superabrasive grains. The cutting edge 3 of the super abrasive grain 2 is made acute by the feed-in of a proper quantity of the polishing material stick, and bonding agent is scooped out, and a tip pocket corresponding to the proper abrasive grain projection quantity 5 is generated, and the cutting performance is restored. Therefore, dressing work can be carried out without suspending the grinding work, and the working time is shortened, and grinding work can be carried out with the always superior cutting performance, and the quality of a worked article and the grinding work efficiency can be improved.

Title: Cooker and manufacture of container for cooker
Inventor: MIYAKE KAZUYA
IPC: A47J37/06
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To enable the usability of a container for a cooker of an electromagnetic induction heating type by reducing the weight of the container. SOLUTION: A pot heat generating layer 14 is provided only on the outer face opposite to a heating coil for a pot body 13 formed of a reliably heat- conducting material such as aluminum 13A. Holes 14C perforated through from outside to inside are formed on the pot heat generating layer 14, an the outside width A of each of the holes C is set larger than the inside width B. The holes are impregnated with aluminum 13A. In addition, plural exposure parts 14B exposed to the outer face are formed on the pot heat generating layer 14. These exposure parts 14B appear by a removing process such as cutting. Thus, a joining member which would otherwise be provided for joining the pot body 13 with the pot heat generating layer 14 is no longer required and thereby the pot itself is lighter due to the decrease in weight of the joining member.  Further, the aluminum 13A with which the holes 14C are impregnated displays an enchoring effect upon the overall joining of the pot body 13 with the pot heat generating layer 14 and, consequently, their partial peeling is prevented from occurring.
