Title: Dna having genetic information of creatinase and use thereof
Inventor: SAGAI HITOSHI
IPC: C12N1/21
Filed: 1987-08-04
Abstract: PURPOSE:To provide a polydeoxyribonucleic acid which is a base sequence coding an amino acid sequence of a polypeptide composed of a creatinase originated from a creatinase-producing microorganism belonging to Bacillus genus. CONSTITUTION:A microbial strain belonging to Bacillus genus and having creatinase-productivity, e.g. Bacillus sp.B-0618 (FERM BP-0750) is cultured under aeration and agitation and the obtained cultured product is centrifuged. The collected bacterial cells are subjected to bacteriolysis to obtain lysed product containing creatinase gene. DNA is separated from the obtained lysed product and purified. The obtained microbial DNA is cut with a restriction enzyme (e.g. EcoRI or HindIII) and linked with a vector fragment cut with the same restriction enzyme. The obtained recombinant DNA is introduced into a host microorganism and the cell is screened by the drug-resistant marker of the vector and the productivity of creatinase to select the microorganism holding a creatinase gene.

Title: Manufacture of build-up printed wiring board
Inventor: ASHIZAWA AKIRA
IPC: H05K3/46
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To suppress the dent quantity of resin which is brought into contact with a copper foil surface and copper foil by stacking copper foil with resin by vacuum pressing for forming the build-up layer of a build-up printed wiring board, and using thick copper foil for copper foil with resin. SOLUTION: A stack object is vacuum-extracted at the time of starting stacking by vacuum pressing and inner air is made to be a thin state. The object is heated in such a state and semi-cured resin is softened. Softened resin is pulled into the through hole of a core layer which is decompressed and the hole is filled with resin. For compensating resin which is made to flow into the hole, resin at the periphery of the through hole in the core layer is drawn, and copper foil on the surface of resin is also drawn to a core layer side so as to form copper foil with resin. Thick copper foil is used for copper foil with resin. Thus, the finishing precision of the characteristic impedance of a pattern can be improved.

Title: Optical scanning control system
Inventor: MIKAMI TOMOHISA
IPC: H04N1/113
Filed: 1982-11-08
Abstract: PURPOSE:To compensate easily exposure energy by controlling an optical scanning period by a data control clock signal and modulating the luminous intensity during the optical scanning period by applying a luminous intensity modulating signal. CONSTITUTION:An output of a photo detector 6 is inputted to a function generator control circuit 8, which controls an output of a function generator 9. This generator 9 outputs a signal having a waveform proportional to 1/cos<2>theta. The output of the generator 9 is fed to a voltage controlled oscillator 10 to output a clock pulse having a period corresponding to the signal level of the output waveform. When the output level of the generator 9 is low, the pulse interval is short and when the output level is high, the pulse interval is longer by a data control clock pulse, which compensates the difference of the beam spot diameter on a photoreceptor depending on the difference of the scanning speed at a running region.

Filed: 1993-08-06
Abstract: PURPOSE:To provide a guide of such contents as coinciding with a driver's natural expectation by adopting a distance up to the near end of a road crossing an intersection as a distance thereto. CONSTITUTION:A navigation device informs a driver of various guide information through an audio output section. CPU subtracts a half D/2 of the breadth D of a crossing intersection from a distance L between the intersection and a vehicle. Then, when the distance (L-D/2) reaches the predetermined value, a signal is sent to the audio output section. The audio output section, upon receipt of the signal, synthesizes an aural signal by assigning the preset distance to a portion of xyz in a typical sentence to the effect. 'Turn to the left after a travel along xyz meters'. Then, the synthesized aural signal is amplified and sounded to inform a driver or the like of a distance up to the approach end of the next intersection and a method to pass the intersection. According to this construction, such a guide as coinciding with the driver's expectation can be provided on the basis of an actual distance up to the approach end of the intersection.

Filed: 1987-08-05
Abstract: PURPOSE:To completely oxidize unburnt components to obtain a clean exhaust gas and to improve the radiation efficiency by disposing an auxiliary catalyst layer in opposition to a main catalyst layer on the downstream side of the main catalyst layer. CONSTITUTION:A mixed gas emitted from an evaporation chamber 4 is supplied with a sufficient amount of air through a secondary air port 5, and rises up in the form of a mixed gas of excess air. Since a main catalyst layer 6 for an oxidizing reaction is provided above the secondary air port 5, the mixed gas flows to the downstream side (inner surface) via communication holes 6a while producing a catalytic combustion mainly on the upstream side (outer surface). The combustion exhaust gas makes contact with an auxiliary catalyst layer 9 which is located further inside from the main catalyst layer 6. When an unburnt components coexist, the combustion exhaust gas is completely oxidized and cleaned, and thereafter the exhaust gas is discharged through a discharge port 8 provided at the upper part. Accordingly, unburnt components produced by incomplete combustion is prevented from being discharged as they are. Further, since the auxiliary catalyst layer 9 is disposed in opposition to the downstream side of th main catalyst layer 6, radiation heat from the auxiliary catalyst layer 9 is discharged to the outer circumstance via communication holes 6a of the main catalyst layer 9.

Abstract: PURPOSE:To increase the response speed by temporarily short-circuiting an integral capacitor at the time of entrance to a proportional band with a prescribed deviation. CONSTITUTION:When the proportional operation where the deviation between the set value of a setter 3 and the detection value of a sensor 1 for the controlled variable of a controlled system is within a preliminarily determined value is detected, an integral capacitor 6-3 of an integrator 6 is short-circuited by a time switch 6-4 whose time is required for discharge of the quantity of charged electricity, and the deviation at this time and a manipulated variable corresponding to the proportional band are temporarily outputted.

Abstract: PURPOSE:To improve the curvature loss of a bent waveguide and to facilitate the manufacture of a waveguide by loading a thin film which varies in thickness in the direction of the radius of curvature on the bent waveguide part and thus equalizing the refractive index distribution of said curved waveguide part. CONSTITUTION:This waveguide has the waveguide part 1 which is bent to specific curvature.
