Title: Disposer
Inventor: KITAZONO MAKOTO
IPC: E03C1/266
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To crush garbage in a short time by providing a disposer with a hopper which forms the peripheral side wall of a crushing chamber, providing the hopper with a step part and forming its upper-part into the shape narrowed with the step part as a boundary. SOLUTION: The hopper 15 is provided with the step part 16 at the position where is above and adjacent to a fixed blade 3 and is formed into the shape narrowed in an upper part with the step part 16 as the boundary. When a motor 1 is activated to operate a rotary plate 6, the thrown-in garbage is pushed to the fixed blade 3 by centrifugal force by the rotary movement of hammers 7 and 8. Movement is stopped by a groove in a part where the garbage is abutted on the fixed blade 3 and rotation is executed by the hammers 7 and 8 in the part where it is not abutted on the fixed blade 3 so that the garbage is cut here. The garbage is moved upwards by this shock. But the garbage is restricted by the step part 16 so that it is kept in the neighborhood of the fixed blade 3. Thus, the garbage is crushed in a short time.

IPC: H01G4/12
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To avoid the layer separation in the boundary between the electrode part and the protection part of a layer-built ceramic electronic component. SOLUTION: Inner electrodes 2 and 3 are formed on the surface of dielectric ceramic sheets. Several tens-several hundreds of the dielectric ceramic sheets having the inner electrodes 2 and inner electrodes 3 are alternately piled to compose an electrode part A. At this point, the thicknesses of the ceramic layers in the outer sides of the piling direction (the thickness direction of the inner electrodes 2 and 3) of the electrode part A are made to be larger than the thicknesses of the ceramic layers in the inner side of the piling direction of the electrode part A. Further, protective dielectric ceramic sheets which do not have inner electrodes on their surfaces are placed on the top and bottom of the electrode part A and all the piled sheets are pressed by a press apparatus to obtain a layer-built unit which is then fired.  The protective dielectric ceramic sheets are used as protection parts B made of ceramic.

Filed: 1990-06-26
Abstract: PURPOSE:To provide a control switch hard to cause unevenness of angle properties even when an external leading out line is sealed by forming a hollow part separated from a part which seals a connecting part of an external leading out line by a rib in a recessed part of a cover and forming a small hole which is communicated with a storage chamber in the hollow part.

The small hole 22 has an inner diameter becoming smaller as it goes farther to back side and a shape extruding to the back side, so that the hole is sealed easily by thermal deposition after sealing the recessed part 18. In the case that the cover 2 is formed in this way, the storage part 5 does not become in sealed state during the sealing process and thus expansion of the cover 2 owing to the increase of the inner pressure of the storage part 5 is prevented at the time of drying a sealing agent at high temperature during the sealing process and consequently, unevenness of angle properties is hardly caused.

Abstract: PURPOSE:To obtain H2 together with I2 or Br2 at a low voltage by carrying out the electrolysis of HI or HBr in a vapor phase using an electrolytic cell contg. a porous holding matrix impregnated with phosphoric acid as an electrolyte between electrodes. CONSTITUTION:Said known electrolytic cell is used as a fuel cell, gaseous HI is introduced into the anode chamber, and vapor phase electrolysis is carried out. I2 produced on the anode is slightly soluble in concd. phosphoric acid. Gaseous H2 is generated from the cathode chamber. When gaseous HI contg. steam is introduced, the steam is dissolved in phosphoric acid on the anode side and shifts to the cathode side in accordance with the difference between the anode and cathode chambers in the partial pressure of steam, and it is evaporated on the cathode side. Accordingly, H2 obtd. from the cathode chamber contains steam, yet the steam can be separated by condensation. Since the transfer of steam in the electrolytic chambers facilitates the transfer of H<+>, the current density can be increased in the presence of steam contained in gaseous HI.
