Title: Automatic mounting method of electronic component
Inventor: SUZUKI KENJI
IPC: H05K13/04
Filed: 1988-09-14
Abstract: PURPOSE:To enable the automatic mounting of a component by a method where in the tentatively set position of the contact point row of the component is corrected by shifting the component if the amount of deviation of the bent contact point row is within the tolerance of mounting with regard to all contact points. CONSTITUTION:The image of an electronic component 5 held by a chuck 6 is taken against a screen as a background, which is processed to obtain the position and the rotating direction of the component 5. In this process, an ideal contact point pitch of the component 5 is previously set, and the positions of all contact points of the component 5 to be actually mounted are obtained and the center position of a contact point row is obtained. And, the actual positions of the contact points are compared with their normal positions, the contact points which deviate the most to the left or the right are noted, and the center position of a contact point row 10' is corrected so as to make the amount of deviation of these two contact points equal to each other. In this state, even if the position-aligned component 5 is possessed of a bent contact point row but its deviation is within tolerance, the component 5 can be mounted on a printed board 2.

Title: Production of alkaline earth metal alkoxide for polymerization catalyst
Inventor: HORIKAWA HIROYOSHI
IPC: C07C29/68
Filed: 1991-08-14
Abstract: PURPOSE:To obtain the subject alkoxides useful, e.g. as a catalyst for polymerization of a diene-based rubber high in the content of trans 1-4 bonds at a low cost and in a high yield by blending a specified alkaline earth metal salt with an alkaline metal alkoxide in an organic solvent and reacting the resultant mixture. CONSTITUTION:One or more kinds of alkaline earth metal salts (e.g. barium nitrate) selected from halides, nitrate, sulfate, acetate, oxalate, etc., of an alkaline earth metal are blended with an alkaline metal alkoxide (e.g. sodium tertiary butoxide) and an organic solvent (e.g. tertiary butyl alcohol) and the resultant mixture is refluxed with stirring at 83 deg.C for 20hr for the purpose of substitution reaction of the alkaline earth metal salts and the alkaline metal alkoxide. After the reaction, the reaction mixture is allowed to stand to sediment unreacted materials and by-products and to separate a supernatant. The organic solvent is removed from the resultant supernatant under a reduced pressure, thus obtaining the objective alkaline earth metal alkoxide (e.g. barium tertiary butoxide) used as a polymerization catalyst.

Title: Level shifter circuit device
Inventor: KAMINISHI TAKAO
IPC: C08F26/02
Filed: 1987-09-11
Abstract: PURPOSE:To save the energy consumption and to miniaturize a circuit by opening and closing a second gate with a second control voltage from a first gate switch opened and closed by a first control voltage. CONSTITUTION:Printing signals VC1-VC3 to control the ON and OFF of thermal head heating bodies R1-R3 gate N channel MOSFET(NMFET) Qs1-Qs3 through CMOS inverter circuits 1a-1c. Respective drains of NMEFETQs1-Qs3 are connected to respective gates of NMFETQd1-Qd3 for driving and connected to current mirror circuits (PMFET)Qc1-Qc3. Since a constant small current flows at an earth from a direct current power source Vf through a constant current circuit composed of a PMFETQCD and a high resistance Rh, the potential of a connecting point 2 becomes constant and the constant current flows at the drain of the PMFETQc1-c3. The PMFETQc1-c3 execute the action of the pull-up resistance and the signal of the low voltage is level-shifted to the control signal of a high voltage.

IPC: H01L49/00
Filed: 1985-10-15
Abstract: PURPOSE:To prevent cracks in a glaze layer to enable to form a heating resistor film on a plurality of ends of a substrate, by a method wherein glaze layer forming main planes of a heating resistor substrate and the other side main planes thereof are laid over with each other, and spacers of metal softer than a glaze layer are inserted between the glaze layer forming main planes. CONSTITUTION:Glaze layer forming main planes of an almina substrate 1 and the other side main planes thereof are laid over with each other, and spacers 3 of stainless plate or aluminum plate are inserted between the glaze layer forming main planes, thus a heating resistor film such as Si-Ta is formed on a number of ends of the almina substrate 1 for forming the glaze layer 2 using a metallizing apparatus or sputtering apparatus. Once the heating resistor film is formed, fine electrode patterns such as Cr-Cu formed on the ends and the main planes of the glaze layer forming surface cannot induce breaking of the electrode patterns on the glaze layer. In addition, the use of the spacers made of a metal having lower hardness than that of the glaze layer prevents cracks in the glaze layer.
