Title: Production of dimethyl azelate
Inventor: YAMATAKA KAZUNORI
IPC: C25B3/29
Filed: 1981-08-05
Abstract: PURPOSE:To obtain captioned products of high purity industrially with high yields and high electric current efficiency in the kolbe's cross electrolytic reaction of monomethyl glutarate with monomethyl adipate by using the monomethyl glutarate obtd. by a reaction of glutaric anhydride with methanol. CONSTITUTION:The monomethyl adipate to be used is obtd. by an ordinary method, for example, reaction of adipic acid and methanol in the presence of an acid catalyst. On the other hand, it is necessary to obtain the monomethyl glutarate by the above-described reaction. The glutaric anhydride used in said reaction is obtd. by dehydrating glutaric acid by heating to 150-270 deg.C under reduced or atmospheric pressure in the absence of any solvent or in the presence of an inert solvent having >=150 deg.C b.p. Said acid is thoroughly dehydrated and is caused to react with slightly excessive methanol. Although the monomethyl glurate may be refined by distillation after the end of reaction, it is more pr eferable to use the reacting liquid as it is to electrolytic condensation. The  sepn. of the product by refining after the end of the electrolytic condensation is accomplished by any of conventional methods.

Filed: 1982-07-15
Abstract: PURPOSE:To eliminate a defect by which the gain is lowered to reduce the luminance and then the contrast on a screen, by providing a circuit which compensates the gain in response to the overlapping frequency of pictures. CONSTITUTION:A memory controller 2 detects an overlap region of pictures between frames with angle signals of the present frame and the preceding frame given from an image pickup device. The detected overlap region is sent to an operator 4 and an adder 10. At the same time, the controller 2 calculates an address from the angle signal of the present frame so as to secure the overlap between the preceding frame and pictures in terms of space and transmits the address to a data memory 3 and a count memory 11. The operator 4 adds the video signal of the memory 3 designated by the address signal given from the controller 2 with the video signal given from an A/D converter 1 and transmits them to the memory 3 as well as to a gain compensator 12. The memory 3 stores the output of the operator 4 at an address position designated by the controller 2. The compensator 12 calculates the gain reduction degree from the overlapping frequency of pictures and given an adverse compensation to the output of the operator 4 to eliminate the gain variation. Then the compensated output of the compensator 12 is converted into an analog signal via a D/A converter 5 and transmitted to a TV monitor, etc.

IPC: H02K9/08
Filed: 1983-07-08
Abstract: PURPOSE:To sufficiently obtain pressure of sealed coil even in the switching to an emergency time by mechanically coupling a sealing oil pump, a normal use AC motor and an emergency DC motor. CONSTITUTION:When an emergency state occurs, the drive force of a normal use AC motor 1 is lost, and the rotation of a sealing oil pump 23 is accordingly dropped, and the exhaust pressure decreases. Then, a pressure switch 6 which is set to the prescribed oil pressure is operated, an emergency DC motor 3 is started, and a sealing oil pump 23 is driven. In this case, since the normal use AC motor 1, the pump 23, and even if the motor 3 are mechanically coupled, the drive force of the motor 1 is lost, the motor 3 is started while rotating by inertia. Accordingly, it reaches the rated rotating speed in a short time. Consequently, the switching time to the emergency time can be shortened, and sealing oil can be sufficiently supplied under the prescribed pressure to a shaft sealing portion 9.

Abstract: PURPOSE:To improve adhesion to a substrate, heat resistance, dry etching resistance, resolution, etc., and to facilitate highly precise microfabricability by using a specified hydroxystyrene type polymer as an essential component. CONSTITUTION:The polymer to be used as an essential component is a hydroxystyrene type polymer represented by formula ( I ) in which Z is halogen, -SO3H, -NO2, -NO, -CH2OH, -CH2SO3M, formula (a), (b), (c), or (d); R1, R2 are each alkyl; R3 is alkyl or aralkyl; X is halogen; M is H, an alkali metal or an alkaline earth metal; 0<P<2; CM is a vinyl monomer; (l) is an optional number including 0; and (n) is >=3 optional number. Said polymer contains <=6wt% low mol.wt. substance equal to a dimer or less, and a ratio of weight average mol. wt. (Mw) to number average mol.wt. (Mn) of 1.8-8.0. Such reduction of the content of a low mol.wt. substance improves adhesion to a substrate, etching resistance, image forming performance, and heat resistance. The reduction of the Mw/ Mn value enhances resolution. Since said polymer of formula ( I ) can be made higher or lower in solubility in the exposed areas than the unexposed areas by selecting the kinds of substituents and photosensitive agents, etc., the obtained resist can be converted into a negative or positive type, and both types of superior microfabricable resists can be obtained.

Title: Metal-ceramic composite substrate

IPC: H05K3/38
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain the composite substrate which has excellent heat cycle endurance and also resisting strength to vibration and is useful for mounting electronic parts by joining a specific metallic material to a ceramic substrate to form a composite substrate having specified bending strength. SOLUTION: This composite substrate is formed by joining an aluminum material to at least one surface of a ceramic substrate (such as aluminum nitride substrate) with e.g. a molten metal joining method, so that the resulting composite substrate has >=20kg/mm<2> bending strength when the distance between two supporting points is 30mm, at the time of applying a three-point bending load to the composite substrate. That is, the composite substrate is provided with a metallic part for mounting electronic parts and on the other hand, a heat radiation plate is joined to the lower surface of the substrate and further, a heat sink body is soldered to the radiation plate. In order to allow the heat sink body to tightly adhere to the fin material, the heat sink body is formed into a U-shape and its both ends are fastened by bolts.  Therefore, at the time of fastening the heat sink body with bolts, unless the substrate has bending strength higher than a certain level, the adhesion between the heat sink body and the fin material is deteriorated and the heat radiation properties of the composite substrate is lowered and also, resisting strength to external force such as vibration is reduced.
