Title: Firing method for ammonium ion-exchange zeolite y and hydrocarbon oil catalytic cracking catalyst containing fired zeolite y
Inventor: MASUDA TATSUO
IPC: C10G11/05
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce breakage of construction of zeolite and increase a SiO2 /Al2 O3 ratio when ammonium ion-exchange zeolite is fired by firing the zeolite under a partial pressure of water vapor and firing it at a temperature higher than the firing temperature. SOLUTION: When ammonium ion-exchange zeolite Y is fired, at first the zeolite Y is fired under a partial pressure of 10% or more of water vapor (first firing step) and thereafter the zeolite Y is treated at a temperature higher than the firing temperature and under a partial pressure of less than 10% of water vapor (second firing step). At that moment, temperature of the first firing step is in the range of 250-500 deg.C and that of the second firing step is in the range of 400-900 deg.C and preferably the temperature of the second firing step is set to 300 deg.C higher than that of the first firing step. And a hydrocarbon oil catalytic cracking catalyst is prepared by dispersing the zeolite Y obtained by firing ammonium ion-exchange zeolite Y in an inorganic oxide matrix.

Abstract: PROBLEM TO BE SOLVED: To dispense with a laser processing by a method wherein a structure consisting of a movable electrode and one pair of fixed electrodes on both its sides is formed on an etching stop film on a silicon wafer and after the movable electrode is made to oppose to a recess formed in the glass substrate and bonded to the substrate, a film on the surface of the wafer is removed and the movable electrode is provided in a form that it is held between the one pair of the fixed electrodes. SOLUTION: Oxide films 21 are respectively formed on both surfaces of a silicon wafer 20 and thereafter, the film 21 on the surface on one side of both surfaces is removed and an Ni film 22 is formed on the surface on one side. After the film 22 is patterned, the wafer 20 is subjected to anisotropic etching using the film 21 as an etching stop layer, a movable electrode 26 consisting of a single crystal layer is formed on the film 21 and gaps are slightly opened on both sides of the electrode 26 to form one pair of fixed electrodes 27 and 28. After the film 22 is removed, a structure 20a consisting of the electrodes 26, 27 and 28 is anode-junctioned with a glass-substrate 10 in such a way that the electrode 26 opposes to a recess 11 formed in the substrate 10 and after that, the film 21 is removed.  Thereby, a semiconductor inertial sensor 30 floated over the recess can be obtained holding the electrode 26 between the one pair of the fixed electrodes.

IPC: H01L23/50
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of the warp of a support pin by working a rigidity imparting means for a support pin to support the mount part of a semiconductor element. SOLUTION: A mount pad (a small pad) 31 and a support pin 32 radially provided in a row in the mount pad 31 are integratedly formed. It is one which is formed by etching or stamping together with a lead frame. It is a great feature that the support pin 32 is formed so as to have a V-shaped cross section. A V-groove 33 is continuously formed from the support pin 32 to the upper surface of the mount pad. A method of forming the V-groove 33 in the upper surface of the mount pad 31 is executed by press work similarly to the support pin. Thus, since a rigidity imparting means is worked for the support pin, the deformation of the support pin due to a load in the manufacturing process of wire bonding, resin seal or the like is suppressed by the rigidity imparting means.
