Title: Moving method for grab type dredger
Inventor: TSUREISHI TSUTOMU
IPC: E02F3/90
Filed: 1987-01-30
Abstract: PURPOSE:To accurately obtain an advance distance and to promote the improvement of dredging accuracy, by pulling up a fixing spud in the center of a ship body and alternately right and left spuds in both boards while rotating a ship reciprocating and advancing by a rotatable crane and bucket. CONSTITUTION:Suspending work, in a condition that a fixing spud 2 in the center and right and left spuds 3, 4 in the stern part of a ship 1 are driven, dropping a bucket 6 to the bottom of the sea instead of an anchor, pulling up the spuds 2, 3 and turning a crane 5, the ship 1 is turned about the spud 4 serving as the center. Under this condition, driving the spud 3 and pulling up the spud 4 next turning the crane 5 in a reverse direction then returning the ship 1 to the original angle, if the spuds 2, 4 are driven, the ship 1 accurately advances by the predetermined advance distance. Further the ship 1 enables its retraction also to be similarly performed. In this way, the ship 1, enabling its dredging accuracy to be obtained while work section to be less decreased, prevents the sailing safety of the other ship from worsening.

Abstract: PROBLEM TO BE SOLVED: To reduce core loss in a steel sheet after finish annealing by allowing it to have a compsn. contg. specified amounts of C, Si, Mn, P, N, Al, S, O, and the balance substantial Fe. SOLUTION: This steel sheet has a compsn. contg., by weight, <=0.005% C, 1.5 to 3.5% Si, 0.05 to 1.0% Mn, 0.03 to 0.15% P, '<=0.005% N, 0.1 to 1.0% Al, <=0.001% S, 0.0008 to 0.0025% O, and the balance substantial Fe. The steel sheet can be produced by an ordinary method for producing a nonoriented silicon steel sheet. Namely, a molten metal blown in a converter is subjected to degassing treatment to regulate the contents of prescribed components, particularly, those of S and O to the above ranges, and successively, casting and hot rolling are executed. There is no need of particularly prescribing the finish annealing temp. and col coiling temp. at the time of the hot rolling, and hot rolled sheet annealing after the hot rolling is not essential as well.  Then, its sheet thickness is regulated to a prescribed one by one time cold rolling or the like, and after that, final annealing is executed.

Title: Partially antique aesthetic ornamental parts and production thereof
Inventor: OKAMURA SHIGETOSHI
IPC: C25D5/10
Filed: 1990-01-31
Abstract: PURPOSE:To produce the partially antique aesthetic ornamental parts high in ornamental value by previously finishing the part in two colors, e.g. black and white or black and golden, and the machining or buffing the part by the barrel method. CONSTITUTION:A watchcase 1 formed of brass, for example, is successively coated with the Ni plating layer 2 and palladium-nickel plating layer 3 as a base layer, a white rhodium plating layer 4 as the intermediate layer and a black ruthenium layer 5 as a finish layer, and then covered with a mask for plating at a specified part. The black ruthenium layer 5 except at the masked part is removed by anodic electrolysis, then the mask is removed, hence the surface is finished in two colors with the black ruthenium layer 5 and white rhodium layer 4, and the surface is lapped with a lapping machine. Consequently, since the ruthenium layer 5 is partially removed, a partially antique aesthetic watchcase having the white layer 4 and a black-white gradation layer 5' is produced.

IPC: H03F3/34
Filed: 1991-02-14
Abstract: PURPOSE:To reduce the AC amplification factor in response to the quantity of a DC component of an input signal in the AC signal amplifier circuit. CONSTITUTION:In the case of amplifying a light receiving signal from a photodiode, a DC component of a current generated in a collector terminal of a 1st Transistor(TR) Q1 is detected by a detection circuit S and a DC component detected by the detection circuit S is used as a bias current of a 2nd TR Q2 and emitter terminal voltages of the TRs Q1, Q2 are compared by a differential amplifier A1 and amplified therein. Thus, a difference voltage appears in a form of cancelling the DC component regardless of the quantity of the DC component in this way. Moreover, when the DC component of the light receiving signal is increased, the amplification factor is reduced immediately depending on the quantity thereby suppressing noise amplification.
