Title: Acceleration sensor and manufacture thereof
Inventor: YOSHIDA HITOSHI
IPC: G01P15/18
Filed: 1995-06-27
Abstract: PURPOSE: To provide an accelerator sensor having no warpage and possible to be improved in yield and its manufacturing method. CONSTITUTION: Each buffer layer consisting of a silicon nitride film is formed on both main surfaces of a first semiconductor substrate. A second semiconductor substrate 11 is joined to one side of the main surfaces of the fist semiconductor substrate 10. Therefore, the buffer layer 12 comes to be interposed between both these first and second semiconductor substrates 10 and 11 in consequence, and thereby an internal stress at high temperature treatment in time of joining is absorbed by the buffer layer 12, so any possible warpage in the first semiconductor substrate 10 is reduced. With this constitution, the yield in the joining process is well improvable.

Title: Production of n-vinylamide
Inventor: JIIN EBERADO PARISU
IPC: B01J23/86
Filed: 1989-06-26
Abstract: PURPOSE: To obtain an N-vinylamide with high selectivity and high conversion without forming a hydrogen cyanide by-product in the operation at atmospheric pressure at a comparatively low temperature by heating a carboxylic acid amide as the starting material in the presence of a specific catalyst.  
     CONSTITUTION: By using a porous catalyst having a cracking index of about 200 or more, a carboxylic acid amide of formula I (wherein R 1  is H, a 1-6C alkyl, 6-9C aryl, substituted aryl; R 2  is a 1-9C alkoxyl, carboxyl, carboxyamide) is heated at about 150-350°C, preferably 200-350°C, suitably in a gas phase to obtain a compound formula II. As the porous catalyst, active carbon is particularly perferred. Further, it is advantageous to carry out this reaction in the presence of an inert gas diluent such as nitrogen and helium, since the partial pressure of the carboxylic acid amide in the reactor is reduced and the heat exchange with the catalyst bed is accelerated, etc.

IPC: F28F17/00
Filed: 1992-06-19
Abstract: PURPOSE:To allow condensed water to drop along a groove up to a lowermost part of an evaporator and to prevent scattering of water droplets by forming at least one or more grooves on linear passages in parallel with a groove for sealing an outer periphery of a refrigerant tube and a groove for forming a partition between the linear passages to be brazed to one another. CONSTITUTION:A laminated evaporator comprises many laminated refrigerant tubes. A pair of molded plates 1A are connected to the tubes, a refrigerant passage is formed therebetween, and a wavy molded plate 2A is inserted into a linear passage of the refrigerant passage. On the other hand, a groove 3 for sealing an outer periphery of the tube and a groove 4 for forming a partition between linear passages are arranged to be brazed to one another. In this case, at least one or more grooves 5 are formed on the linear passage in parallel with the grooves 3, 4. Thus, water condensed on a heat transfer surface is fed down from the surfaces of the tubes through the grooves 5 and hence to prevent scattering of the condensed water rearward by an air flow.

Title: Limit switch for opening and closing drive device
Inventor: NISHIKAWA KATSUMI
IPC: B60H1/00
Filed: 1986-07-09
Abstract: PURPOSE:To aim at surely opening and closing a shut-off member and at preventing overload of a motor, by stopping a motor for driving the shut-off member after the shut-off member is opened and closed and then is stopped, and by absorbing the drive force of the motor with the use of transmission members after the shut-off member is stopped. CONSTITUTION:When a conductor plate 82a is energized, current runs through a conductor plate 82b by way of a contact piece 81a so that a motor 71 rotates to cause a transmission gear 72g to rotate in the direction 1, and therefore, a transmission gear 72h and an output shaft 7a are rotated in the direction E. As a result, a motor link 34 is rotated to close a shut-off member which is not shown in the drawing. At the time of stopping of the shut-off member, the contact plate 81 is held in contact with conductor plates 82a through 82c, and therefore, the energization of the motor 71 is continued. Accordingly, the transmission gear 72h is urged in the direction J in association with the rotation of the transmission gear 72g in the direction 1, and therefore, the gap between an interlocking member 72i and a stationary member 74 is decreased. As a result, a brush 81b and the conductor plate 82b are separated from each other, thereby the motor 71 is initially stopped.

IPC: G01R15/18
Filed: 1980-11-14
Abstract: PURPOSE:To make it possible to measure three-phase A.C. without any error, by connecting a resistance with secondary side of a current transformer in parallel, and also by inserting the resistance in the secondary side of the currect transformer when measuring T-phase and R-phase currents. CONSTITUTION:Resistance R1 and R2 are connected with secondary sides of current transformers 1 and 2, respectively, which are supplied with R-phase current iR and T-phase current iT, and at the same time, an AC ammeter 5 is connected through changeover switches 3 and 4, and resistances R11 and R21 are also connected through changeover switches 13 and 14. At this time, resistances values of the resistances R1, R2, R11 and R21 are appropriately selected so as to satisfy an equation of (R1.R11)/(R1+R11)=(R2.R11)/(R2+R21)= (R1.R2)/(R1+R2). When measuring respective currents of phase of R, T and S,  the measurement is performed by turning ON only the switches 3 and 13, the  switches 4 and 14 and the switches 3 and 4, respectively. It is possible, by so  doing, to prevent secondary side of a non-selected current transformer from  being kept open and also to measure alternate current accurately.
