Title: Dynamic speaker
Inventor: MIZUKOSHI SUSUMU
IPC: H04R9/06
Filed: 1980-05-02
Abstract: PURPOSE:To secure a sufficient sound pressure without any unnatural sound quality, by attaching a magnetic circuit to a frame so that the magnetic circuit part can have a vibration to the frame. CONSTITUTION:When a force is applied to a voice coil 13, a reaction force in a direction opposite to the force applied to the voice coil 13 is applied to the magnetic circuit part. Furthermore an edge 19 supporting the magnetic circuit part can have a vibration having a point of resonance at a low band having a high level of sound pressure. As a result, the magnetic circuit part has a vibration in the direction of an arrow as so that it shifts in a direction opposite to the shift of a vibrating plate 10. Thus the level of sound pressure is attenuated at a low band to obtain a flat characteristic.

Title: Wafer etching method
Inventor: TANAKA KAZUO
IPC: H01L21/68
Filed: 1994-03-02
Abstract: PURPOSE:To provide a wafer etching method whereby a more functional structure than conventional ones can be formed while a uniform etching performance is maintained. CONSTITUTION:In a shower etching method, a wafer is held fluctuation-wise while its surface is turned upward, and by a shower nozzle 1 in an etching processing vessel 5, an etching liquid is poured in a shower state on the wafer from above it. By the executing of the etching through this shower etching method, the etching liquid is fed uniformly over the whole surface of the wafer, and etching-reaction-generated bubbles are removed quickly from the surface of the wafer. Therefore, the variation of the thicknesses of the etching liquid accumulated on the surface of the wafer can be reduced, and in addition, the rear surface of the wafer can be so kept as to be in a non-etched protection state. Also, as the protective method of the one side of the wafer, the protection using a resin is performed, and the height of the resin cover is made not larger than 0.5mm. Thereby, after the etching liquid is poured on the wafer, it flows quickly from the surface of the wafer, and as a result, the new etching liquid is poured uniformly on the whole surface of the wafer.

Title: Prevention of coarsening of catalyst
Inventor: FUJIMORI KUNIAKI
IPC: C01B3/22
Filed: 1979-05-15
Abstract: PURPOSE:To prevent the coarsening of catalyst by a method in which a purge gas is introduced to destroy coarsened particles at the time when a pressure loss begins to reduce by watching the pressure loss of the fluidized bed portion of a catalyst containing a specific proportion of iron in its reduction process. CONSTITUTION:In the fluidized bed portion 6, where the reductive reaction of a catalyst containing 30-60% iron with coke is carried out, the lowering of pressure loss due to the formation of gas-permeable paths occurs in the early period of bogging (coarsening), in which weak bonding occurs among catalysts, and the pnenomenon is watched by the differential pressure meter 15. When the pressure loss is lowered beyond a given value, a purge gas, e.g., nitrogen, etc., from introduction line 16 connected to the CO2 gas-introduction line 7, for example, is introduced at a flow rate of 50cm/sec in order to destroy compatively fragile particles, thus permitting good fluidized condition of catalyst particles to be maintained.
