Title: Production of epoxy resin
Inventor: OTSU MASAAKI
IPC: C08G59/06
Filed: 1989-05-25
Abstract: PURPOSE:To produce an epoxy resin of a high epoxy value which scarcely undergoes any side reaction and requires a short time for its separation in a high production efficiency by reacting a polyphenol with epichlorohydrin by slowly feeding the former into to the latter. CONSTITUTION:A polyphenol (e.g. an aromatic compound having at least two phenolic hydroxyls, such as biaphenol A or hydroquinone, or a novolac obtained by condensing the above compound with an aldehyde in the presence of an acid or an alkali catalyst) is reacted with epichlorohydrin by slowly feeding the polyphenol into the epichlorohydrin. Because a large excess of the epichlorohydrin over the phenolic hydroxyls is present in the reaction system according to the above process, side reactions can be controlled to suppress the formation of polymer; therefore the time necessary for separation is very short and the production efficiency can be increased. As compared with the conventional process, side reactions of the epoxy resin can be suppressed, so that an epoxy resin of a low epoxy equivalent, namely a low impurity content can be produced.

Abstract: PURPOSE:To prevent the decrease in bondability of a wire by a method wherein no interlayer insulating film is interposed under a bonding pad region. CONSTITUTION:On a silicon substrate 1, the first wiring layer 2 consisting of aluminum, an interlayer insulating film 3, the second wiring layer 4 and an insulating film 6 are superposed sucessively, the second wiring layer 4, which constitutes the contact section 11 of the first wiring layer 2 and the second wiring layer 4, is covered by the insulating film 6, a part of the second wiring layer 4 is extended on the interlayer insulating film 3, then aparted from the film 3 and reaches and comes in direct contact with the silicon substrate 1, and the end part of the extended film 3 constitutes a bonding pad 7, whereon a wire 8 is bonded.

Filed: 1995-05-31
Abstract: PURPOSE: To quickly correct dislocation of a cutting position between a spectacle lens and a cuter in a grooving machine for the spectacle lens for grooving a groove on the peripheral edge of the spectacle lens. CONSTITUTION: Magnets 3a and 3b are fitted respectively on both the ends of a lens pedestal 3.

IPC: H01R35/04
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To quickly detect disconnection of a conductor in a flexible cable also of an important circuit other than an air bag circuit and enhance reliability in the connector requiring plural flexible cables. SOLUTION: Air bag circuit conductors 11 for plural circuits are arranged in a lump to one flexible cable 4. Since the same flexible cable 4 can be monitored with plural disconnection diagnostic checking system assembled as an accessory of each air bag circuit, the disconnection of a conductor 12 corresponding to an important circuit other than the air bag circuit can be detected. If another circuit conductor 12 is arranged between air bag conductors 11 installed in the flexible cable 4, emergency short circuit trouble can surely be avoided. If a lead block to which the flexible cable 4 is connected is fixed to a rotary connector and output terminals of air bag circuit conductors 11 are gathered in a lump, since an outside connector is simply connected to or removed from the lead block, assemblability in a fixing stage can be enhanced.
