Title: Flanged waveguide and its manufacture
Inventor: ISO AKIO
IPC: H01P1/04
Filed: 1983-06-24
Abstract: PURPOSE:To improve flanging strength and flanging precision greatly by forming a waveform part and flange parts in one body by using a die while holding the continuity of fiber. CONSTITUTION:Prepreg sheets 1 longer than the waveguide part are stacked on a mandrel 5. Then, at least four cuts are formed in the prepreg sheets at both ends in the axial direction of a waveguide and the sheets are bent at right angles to the axis of the waveguide to obtain prepreg sheets 3 as part of a flange. On the other hand, prepreg sheets 2 in the shape of the flange part which have holes conforming to the section of the waveguide are stacked alternately between and/or both sides of layers of the bent prepreg sheets 3. The shape of the prepreg sheet laminate corresponding to the flange part is made uniform and patches 6 having surfaces perpendicular to the mandrel 5 are set on both sides of the mandrel 5 to perform heat formation under pressure. The patches 6 are detached after the formation and the mandrel 5 is drawn out.

Title: Electric conductive packing material with cushion function
IPC: B65D81/03
Filed: 1992-04-07
Abstract: PURPOSE:To provide a packing material which has an electric conductive ability in addition to a cushionning function like corrugated board, by pressing with heat non-wooven cloth with a specified electric resistance ratio, in which electric conductive synthetic fibers are mixed, on one face of liners or the center board of corrugated board to form the corrugated board so as to direct the adhesion face of non-wooven cloth mixed with the electric conductive synthetic fibers to the superficial face. CONSTITUTION:Non-wooven cloth mixed with 0.5-30% of electric conductive synthetic fibers in weight to have 10<2>-10<9>OMEGA.cm in electric resistance ratio is stuck on the liners or the center board composing corrugated board to make one side- or both sides-corrugated board so as to direct the stuck electric conductive non-wooven cloth to the external face. In this way, the electric resistance ratio becomes variable by selection of the mixed ratio of the electric conductive synthetic fiber or electric conductive complex synthetic fiber. Accordingly a packing material having an appropriate electric resistance ratio for a purpose can be obtained. Moreover, since non-wooven cloth evenly mixed with electric conductive synthetic fibers is stuck on the external face of corrugated board by pressing with heat, so that it may not be easily peeled off, conductivity can be sustained for a long term and the packing material can be discarded easily.

Title: Waveform shaping circuit for index signal
Inventor: ISONO KATSUO
IPC: H04N9/24
Filed: 1979-09-04
Abstract: PURPOSE:To produce the index pulse having no change of the phase, by forming the threshold voltage which varies in proportion to the amplitude of the index signal. CONSTITUTION:The index signal detected by the photodetector 21 is divided through the BPF22 into the index signals having the opposite phase to each other. These two signals are supplied to the waveform shaping circuit 50 consisting of the amplitude detector 60, the sample holding circuit 70 and the level comparator 90 each. Then the both signals undergo a full-wave detection through the detector 60, and this detection signal receives the sample holding at the sample holding circuit 70. The sample holding voltage varies in proportion to the change of the amplitude of the index signal. Thus this voltage is used for the threshold voltage of the comparator 90 to receive a level comparison with the index signal. In such way, the index pulse with no change of the phase can be obtained although the amplitude of the index signal may vary.

Title: Coffee maker
Inventor: SHIRAI YOSHINARI
IPC: A47J31/057
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of short-circuit and electric shocks as much as possible by turning a water tank upper part opening peripheral edge to constitution for making water overflow from a part other than the part positioned at the upper part of a power source switch so as not to make the overflowing water reach the power source switch along a water tank outer wall surface. SOLUTION: When more than rated capacity of the water is erroneously put in a water tank 2 and the water is made to overflow from the water tank 2, the overflowing water reaches a lower part through the outer wall surface of the water tank 2. In this case, since a projection part 11 is provided on the upper part of the power source switch 10, the water hardly overflows from the upper part of the power source switch 10. Thus, the overflowing water is suppressed from entering the power source switch 10 and is not accumulated in a conducting part inside the power source switch 10 and the danger of the short-circuit and the electric shock is eliminated.  Also, the water overflowing from both sides of the projection part 11 is obstructed by steps 12 formed by the expansion of the water tank outer wall surface in a range from the projection part 11 to the power source switch 10, the overflowing water is prevented from entering the power source switch 10 and the danger of the short-circuit and the electric shock is eliminated.
