Inventor: SOGLI LORIS
IPC: A61P31/04
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a compound useful as the subject intermediate in high purity and yield by deacylating a compound formed by reaction between each specific glutaryl aminocephalosporanic acid and thiol. SOLUTION: In the form of an aqueous solution, glutaryl 7- aminocephalosporanic acid (7-ACA) is made to react with 3-5mols of a compound of formula II (R is a heterocycle containing at least N and optional containing S or O) per mol of the glutaryl 7-ACA, followed by, according as necessary, recovering an excess of the compound of formula II to obtain a compound of formula III in the form of an aqueous solution. The resultant compound of formula III is deacylated enzymatically to obtain the objective compound of formula IV (R<1> and R<2> are both H, or one of them is H and the other an acyl). Respective compounds of formula V and formula VI derived from the compound of formula III are new compounds.

Abstract: PROBLEM TO BE SOLVED: To prevent set stones from being deviated even at the time of vibration while providing the smooth feeling of usage by serially providing plural recessed parts with the respective intersections of ruled lines on a GO board, which is formed by expressing the ruled lines on the surface of board, and displaying the ruled lines continued inside and outside the respective recessed parts. SOLUTION: A main body 1 of GO board is formed from an almost rectangular woody plate, recessed parts 2 are formed from curved surfaces approximated to the curved surfaces of GO stones as circular hollows, its depth is leveled a little lower than the 1/2 thickness of average GO stone, for example, and the recessed parts 2 are continuously provided at the setting enable positions of GO stones. Ruled lines 3 are displayed continuously both inside and outside the recessed parts 2 and sized similar to ordinary GO stones. Thus, since the GO stones are positioned at the recessed parts, the GO stones can be prevented from being deviated by vibrations and further, handling is facilitated in comparison with the method using magnets.

Title: Civil engineering and architectural fire resistant sheet
Inventor: KOJIMA ISAO
IPC: B32B3/24
Filed: 1994-12-09
Abstract: PURPOSE: To improve the handling efficiency and enhance the construction efficiency by forming a coating layer, which produces an expanded fire-retardant layer when heated on one or both surfaces of a flexible base material thereby to reduce the thickness thereof. CONSTITUTION: A coating material in the form of viscous fluid is applied to the surface of a base material 10, which is then dried to form a coating layer 30 which produces an expanded fire-retardant layer 20 when the layer 30 is heated. At that moment, a primer treatment layer 20 is disposed between the layer 30 and the material 10 to provide sufficient joint strength. Thus transfer of heat to the material 10 is reduced by the layer 20 to produce fire resistance. And an air seal, as a whole, is formed to improve thermal insulating performance. Further when the coating layer 30 is porous, it is covered with a waterproofing layer 60. As a result, in general use, the thickness can be reduced so that handling efficiency can be improved and special fire resistive seal is not needed so that the construction efficiency can be improved.

IPC: F25B27/00
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce NOX exhausted from an engine upon high load operation of a compressor by changing over the whole capacity of the capacity of a compressor when an air conditioning load is increased and the compressor reaches a load above maximum number of revolutions with its partial capacity. SOLUTION: Room temperature detected by a temperature sensor 20 and a set temperature set by a room temperature setting unit 21 are inputted into an air conditioning load estimation means 22, and the estimated air conditioning load is inputted into a capacity/number-of-revolutions determination means 23 where the capacity of a compressor 2 and the number of revolutions of the same are determined in conformity with a map inputted from memory means 24. The capacity is outputted to a capacity control mechanism 2A to change over the capacity of the compressor 2 to partial capacity or whole capacity. The number of revolutions is outputted to a speed change gear 1A, and the number of revolutions of the engine 1 is adopted as determined ones.  Hereby, during the operation of the compressor at the partial capacity the torque of the engine is reduced and exhausted NOX is reduced even when the number of revolutions approaches the maximum number of revolutions.

Title: Bipolar transistor and manufacturing method
Inventor: MOTOYOSHI MAKOTO
IPC: H01L27/06
Filed: 1993-11-11
Abstract: PURPOSE:To provide stable operational characteristics in a bipolar transistor through a self-alignment state held between a base and an emitter, by coating a face of a base region in a sidewall spacer with an oxide film, and re-flowing a reflow film deposited on the face. CONSTITUTION:After an emitter contact part is formed in a polysilicon base, the upper and side faces of the polysilicon base is covered with a silicon nitride film. An oxide film 7 and a reflow film 8 are deposited one by one, and the film 8 is put in a reflow state while the intrinsic base region is still covered. The reflow film 8 and the oxide film 7 are removed in an anisotropic etching step to form an emitter contact. Then, the intrinsic base region is protected from an impurity diffused from the reflow film 8 or a high density impurity diffused from a base polysilicon 6. In this way, the film 8 can be subjected to reflow without contaminating the intrinsic base region, so a transistor with stable characteristics can be obtained.

IPC: H04N1/04
Filed: 1987-12-07
Abstract: PURPOSE:To suppress vibration of a motor and to prevent noise or vibration of carrier, by exciting an electromagnetic clutch in the vicinity of a resonance frequency and connecting a suppressing means. CONSTITUTION:An instruction for connecting an electromagnetic clutch 19 is fed to the electromagnetic clutch 19 only when sub-scanning is performed in the vicinity of driving frequency with which a step motor 12 resonates. Upon connection of the electromagnetic clutch 19, vibration of the step motor 12 is converted through a damper 17A into thermal energy so as to suppress vibration. Consequently, resonance of the step motor 12 does not cause increase of vibration of carrier and the like even at resonant driving frequency.

The pseudo indirect lighting cover 16 is desirably provided on the light globe 14 in such a manner as to be removable.  The light transmissivity in the front part of the lighting globe 14 is set smaller than in the other part, whereby the manufacturing cost can be reduced by the reduction in number of part items.
