Title: Production of aldehyde cyclic trimer
Inventor: SATO TOMOJI
IPC: B01J27/19
Filed: 1991-02-22
Abstract: PURPOSE:To produce an aldehyde cyclic trimer used as a synthetic raw material for trioxane derivative, etc., advantageously on process. CONSTITUTION:An aldehyde expressed by the formula R-CHO (R is hydrocarbon residue) is reacted in the presence of a catalyst consisting of a heteropolyacid. Thereby the reaction liquid is separated into two liquid phases consisting of a product phase and catalyst phase, after reaction. As a result, aldehyde cyclic trimer can be obtained by taking out the product phase from the reaction liquid by liquid separation treatment.

IPC: H03K19/003
Filed: 1988-03-07
Abstract: PURPOSE:To eliminate the reduction of reliability due to the backward current stress between the base and the emitter in a bipolar transistor and to prevent a pseudo collector current from flowing at the quiescent time by connecting the respective drain and source terminals of an NMOS transistor and a PMOS transistor between the base and the emitter of the bipolar transistor. CONSTITUTION:When a switching circuit 100 is in an active state, the control signals of C1=0 and C2=1 are given so that both NMOS102 and PMOS103 are turned off. Consequently, a current from an input I11 flows into the base of NPN101 and turns on NPN10. When the switching circuit 100 is in a dormant state on the other hand, the control signals of C1=1 and C2=0 are given so that NMOS102 and PMOS103 are simultaneously turned on. Consequently, the potential of the base and the emitter in NPN101 become almost equal and a backward bias is not hung between the base and the emitter through the potential of an output O1 changes from a '0' level to '1'. Furthermore, it is prevented that NPN101 is turned on so as to flow the pseudo collector current.

Title: Phase shift grazing incidence interferometer
Inventor: NISHIKAWA NAOYUKI
IPC: G01B9/02
Filed: 1991-03-15
Abstract: PURPOSE:To introduce a phase shift method which does not require movement of a body to be measured to improve measurement accuracy by providing two polarizing plates to linearly polarize light from a light source and having object light and reference light interfered with each other on an observation surface. CONSTITUTION:Coherent light from a light source 1 is linearly polarized by a first polarizing plate 21 and divided into reference light 8 and object light 9 by a diffraction grid 7 which respectively enter a diffraction grid 12 directly or through a shift plate 11 after being applied to a body 10 to be measured through the phase plate 22. The object light 9 passes through the phase plate 22 twice and is changed in a polarizing direction by 90 deg. and overlays the reference light 8 in the gird 12, while they do not interfere with each other since polarizing directions are perpendicular to each other. The light is incident to a phase element 23, where a phase shift of a known amount can be applied between the reference light 8 and the object light 9 thereby providing a phase shift method. Then the light is transmitted through a second polarizing plate 24 to have the reference light and the object light 9 interfered with each other on an observation surface 15. Thus introduction of the phase shift method allows phase measurement of one or less interference fringe allowing determination of unevenness of stages.

Abstract: PURPOSE:To minimize weld defects and to improve the yield of a product by detecting successively the max. value of the arc voltage during half cycles, determining an average value and standard deviation by using the detected value and detecting the weld defects. CONSTITUTION:The max. value of the arc voltage during half cycles of AC arc welding is successively detected. The number of the times when the max. value of the arc voltage exists between the respective levels is counted. An average value and standard deviation are determined simply by continuous calculation using the count value. The average value and standard deviation attain the values approximately equal to the average value and standard value determined in accordance with the refiring voltage itself and therefore quick detection is possible. The weld defects are thus minimized and the yield of the product is improved.
