Title: Alumina-sic-c lining brick for iron ladle
Inventor: NAKAI MASATO
IPC: F27D1/04
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent the fall-down of a lining brick caused by stick-out even in the case of using for a long period of time and the lowering of erosion resistance by forming the upper surface and the bottom surface of the brick into a trapezoid-shape or fan-shape and specifying the length difference between an upper side or an inside chord and a lower side or an outside chord. SOLUTION: As the lining brick for an iron ladle for the pretreatment of the molten iron which has low m.p. and easily invades into the joint part, an alumina-SiC-C brick excellent in the erosion resistance, is used. This brick desirably has the composition of about 20-96% Al2 O3 , about 0-60% SiO2 , about 1-15% SiC and about 3-20% C. Further, the upper surface and the bottom surface are formed into the trapezoid-shapes or the fan-shapes. Furthermore, the length difference between the upper side of the upper surface and the bottom surface or the inside chord A1 and the lower side or the outside chord A2 is made to 10-30% of the brick thickness B.  In this way, even in the case that the thickness of the brick becomes thin, the sticking-out is made sufficiently large to prevent the fall-down of the brick and further, the joint thickness is uniformized at the time of laying the bricks to prevent the joint-opening, and the cost of the lining material and the exchanging man-hour of the brick can be reduced.

Title: Control of frequency converter
Inventor: MOTOBE MITSUSACHI
IPC: H02P21/22
Filed: 1980-04-18
Abstract: PURPOSE:To ensure continuation of a stable operation with a simple construction against sudden change in the load of a motor by compensating control of an output voltage of a frequency converter according to the current flowing through an ac motor to be driven thereby. CONSTITUTION:An output voltage of a frequency converter which is adapted to drive an ac motor with an ac power or by converting a dc power into an ac power with an desired frequency is controlled in a compensating manner according to the  current flowing through an ac motor. For example, a function generator 15 is used  to generate an output signal of a current transformer 7, namely, a signal according to the current of a motor 5 which is added to an output signal of a voltage/frequency setter 9 and a deviation between the resulting signal and the output signal  of a detection transformer 8 is amplified 10. The deviation between the output and  a current signal is amplified 11 to control a power rectifier 2 by way of a gate pulse generator 12 while a power inverter 4 is controlled by way of a voltage-frequency  converter 13 and a pulse distributer 14 with an output signal of the setter 9.

Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To improve the strength and attain light weight by making the wall thickness of rim part corresponding to the tooth bottom part thicker than the wall thickness of rim part corresponding to the tooth center part. SOLUTION: A thick all part 11 in which the wall thickness (f) of rim part 6 corresponding to a tooth bottom part 5 is made thick is connected to a thin wall part 12 in which the wall thickness (g) of the rim part 6 corresponding to a tooth center part 12 is made thin through a smooth round part 13 and thus a corrugated form is formed in the lower surface of the rim part 6.

Filed: 1990-03-02
Abstract: PURPOSE:To decrease number of one action service check points and to quicken lighting speed of a lamp by providing an assignment number check section and releasing its registration when a key is registered as one action key. CONSTITUTION:When a call comes to an ISDN telephone set, an incoming control section 10 is started. The incoming control section 10 uses at first an assignment number check section 11 to check whether or not a key number included in the incoming information from an exchange is in existence in the telephone set. When no number is included by the check, a reply reject is returned, and when a relevant key number exists, a one action key registration check means 111 is operated next and whether or not the key is registered as the one action service key is checked, and when registered, the registration is released. When the check by the assignment number check section 11 is finished, the processing such as lamp state revision is implemented. Thus, number of one action service check points is reduced to quicken the lamp lighting speed.

Title: Formation of multilayer wiring film
Inventor: HAMA MASAHARU
IPC: H01L21/768
Filed: 1984-03-15
Abstract: PURPOSE:To prevent the generation of inferior layer insulation between a first layer wiring film and a second layer wiring film by a method wherein after the protruded part of a first interlayer insulator on an abnormally grown part on the surface of the first layer wiring film is removed, a second interlayer insulator is formed. CONSTITUTION:A first interlayer insulating film 41 is formed on the surface containing the abnormally grown part 3a of a first layer wiring film 3. At this time, a protruded part 41a is formed at the part on the abnormally grown part 3a on the surface of the film 41. Then a resist film 6 having film thickness thinner than height of the protruded part 41a is formed on the surface of the film 41. Then the protruded part 41a is etched to be removed using the film 6 as a mask, and the head part of the abnormally grown part 3a is exposed. Then a second interlayer insulating film 42 is formed extending over the whole surface, and after then a second layer wiring film 5 is formed on the surface of the film 42. According to this method, because the film 42 having no thin part of film thickness exists between the head part of the abnormally grown part 3a of the film 3 and the film 5, a fear to generate inferior interlayer insulation between the films 3, 5 is removed.

This S part is clamped by the substrate 1 and the protective film 4. The soft magnetic film 3 is worked to the main magnetic pole 8 while the film is clamped by the substrate l and the protective film 4, by which the thickness of the main magnetic pole 8 is easily confined to <=1mum.

Title: Method and device for purifying fluid by adsorption
Inventor: RABUI JIYAIN
IPC: B01J20/18
Filed: 1991-03-15
Abstract: PURPOSE: To provide a method and a device to eliminate steam and carbon dioxide from air by temperature-swing adsorption. CONSTITUTION: This process relates to the method and the reactor to purify a fluid by adsorption when the fluid flows from the inlet to the outlet of the vessel along an axis of the vessel which contains particles for treating the fluid. An improvement of this process is that particles are distributed in a first region connected to the inlet and a second regions connected to the outlet, while the average grain sizes of the particles in the second region is smaller than the average grain sizes of the particles in the first region. A length of the second region along the axis is selected preferably to be at least equal to the length of the mass transfer zone estimated for the adsorption process. When the particles with smaller sizes are used, the length of the mass transfer zone is reduced and a utilization efficiency of the adsorber is increased.
