IPC: C07C1/00
Filed: 1985-11-13
Abstract: PURPOSE:To suppress the formation of by-products such as 1-2C low-boiling gas and the occurrence of fly loss of a metal supported on a zeolite catalyst, by using a particular catalyst in reforming aliph. hydrocarbon and (or) alcyclic hydrocarbon to produce arom. hydrocarbon. CONSTITUTION:A metal belonging to the Group II b of the periodic table (e.g., Zn or Cd) is supported on a silica zeolite having a high silica content, i.e., an SiO2 to Al2O3 ratio of 8 or more (e.g., ZSM-5 or ZSM-11 zeolite). The zeolite is pretreated with a presulfiding agent (e.g., hydrogen sulfide or carbon disulfide) by heating under pressure to prepare a catalyst. Aliph. hydrocarbon and (or) alicyclic hydrocarbon are reformed in the presence of the catalyst to produce arom. hydrocarbon in a high yield.

Abstract: PURPOSE:To enable obtaining a less expensive reciprocating motion device of simple constitution requiring easy installation and maintenance works and ensuring freedom from a noise by providing a rod integrated with a superconductor and an electromagnetic coil for generating an electromagnetic resilient force on the superconductor in a vessel. CONSTITUTION:A superconductor 1 is integrated with a rod 2 connected to a driven body 5, and an electromagnetic coil 3 for generating electromagnetic resiliency on the superconductor 1 and the rod 2 are fixed to a frame body 4. Switches 6a and 6b for exciting the electromagnetic coil are operated, thereby exciting electromagnetic coils 3a and 3b. Then, the superconductor 1 moves right or left due to Meissner effect. Instead of a driving force with compressed air or oil, the electromagnetic resilient force of the superconductor 1 due to the Meissner effect is thereby employed and constitution becomes simple without any need of an air or oil compressor, an electromagnetic valve, a pipe line and the like. Also, not only the inner surface of a vessel does not need high- precision finish, but also a noise is eliminated and installation and maintenance become easy.

Abstract: PURPOSE:To prevent foreign particles from readhering onto semiconductor substrates and infiltrating into processing chambers by making a dielectric substance coating the inner wall of a load-lock chamber adsorb foreign particles brought from outside into the equipment electrostatically by electrification. CONSTITUTION:A semiconductor substrate cassette and semiconductor substrates are contaminated by resist or other dust particles.

In the case where the inner wall of the load-lock chamber 5, 6 is coated with Teflon, its surface is electrified by friction with the turbulence, and foreign particles swirled up are a all adsorbed by Teflon 10 by static electricity. As a result, they are prevented from adhering onto semiconductor substrates and infiltrating into the processing chamber 3, so that the processing chamber is always kept clean Foreign particles adhering on the inner wall can be removed readily by regular wet cleanings. Further, applying voltage onto the Teflon 10 to induce static electricity increases dust-collecting capacity.

Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To properly judge whether or not hot bathtab water reheating and hot water supply are simultaneously executed in a one can two water type hot water supplier. SOLUTION: In a bathtab water reheating function equipped hot water heater wherein there are disposed in a common heat exchange part an additional boiling water communication pipe and a hot water supply communication pipe, when hot water supply and bathtab water reheating are simultaneously required (steps 101, 106), a microcomputer evaluates a hot water supply request number Q1 (step 111). Then, a circulation pump is turned on (step 113), and bathtub water temperature is read in (step 114). Further, an estimated distribution number Q2 to a hot water supply side in a maximum number Qmax is estimated based upon the bathtub water temperature (step 116), and the estimated distribution number Q2 is judged whether or not it is larger than the hot water supply request number Q1 (step 117).  If yes, then the hot water supply request number is assumed to be ensured even with the simultaneous execution of the hot water supply and the bathtab water reheating, and this is permitted, while if not, then the circulation pump is turned off to prohibit the bathtab water reheating.
