Title: Method of steering ship
Inventor: KITOU HIROAKI
IPC: G05B13/00
Filed: 1983-04-21
Abstract: PURPOSE:To minimize the fuel consumption of a ship, by automatically adjusting the control system parameter of an automatic steering device so that the resistance to which the ship is subjected is made minimum in accordance with an evaluating function value. CONSTITUTION:When a set compass direction PSIr and an actual compass direction PSI of a ship 3 are delivered to a digital computer 1 that computes a steering angle with which the deviation between the PSIr and the PSI is made null. Then a steering angle instruction Rc is fed to a steering unit 2 by which the steering angle R is set. The turning angle PSI' of the ship 3 is fed to a gyrocompass 4 to measure the actual compass direction PSI of the ship 3. This compass direction PSI is fed to the digital computer 1 to be compared with the set compass direction PSIr. Then the above-mentioned steps are successively repeated. With this method a parameter vlue which minimizes an evaluating function value is set to a control system to automatically compensate the parameter value of the control system so that the resistance to which a ship is subjected during the sailing of cource keeping, may be made minimum to minimize the fuel consumption of the ship.

Title: Electrophotography
Inventor: OOHARA KATSUNOBU
IPC: G03G15/047
Filed: 1978-06-09
Abstract: PURPOSE:To enable retention copying capable of forming a plurality of copied images from the same latent image on a screen, by forming a static latent image on a photosensitive screen having a surface insulating layer and by applying a specified corona discharge for modulation. CONSTITUTION:Photosensitive screen 4 having photoconductive layer 2 and insulating layer 3 on conductive screen 1 is uniformly charged on layer 3 negatively by pre-charging. Subsequent exposure to light 12 from original 11 and AC corona discharge render the surface voltage of light area L of layer 3 positive. Next uniform whole surface exposure forms a static latent image with changed voltage on dark area D of layer 3. Succeeding application of modulation corona discharge across corona wire 8 and conductive substrate 5 of recording material 7 through voltage sources 9 and 10 connected to screen 1 hinders passing of positive corona ions in virtue of an electric field shown by full lines alpha on light area L. On the other hand, on drak area D, the electric field shown by full lines beta permits the corona ions to effectively arrive at insulating layer 6 of material 7 in a state of the latent image slightly erased.

Title: Chrominance signal processor
Inventor: MATSUMOTO TOKIKAZU
IPC: H04N9/84
Filed: 1985-04-03
Abstract: PURPOSE:To fasten a transient response and to reduce color sagging and also to improve an S/N by passing a non-correlation signal having a low level when calculating and feedbacking the signal to an input from a chrominance signal inputted and the signal that is delayed by 1H from the chrominance signal and cutting a feedback loop when the correlation is low with a non-linear process circuit which does not pass the signal having high level. CONSTITUTION:The chrominance signal inputted from an input terminal 1 is subtracted the output of a non-linear circuit 8 by a subtractor 2 and is inputted to a 1H delay line 3. The output of the 1H delay line 3 is added to the chrominance signal inputted at an adder 4 and inputted to a non-linear circuit 5. Also the signal is sent to the non-linear circuit 8 and is feedbacked to the subtractor 2. The output of the nonlinear circuit 5 is subtracted from the inputted carrier chrominance signal and is outputted to an output terminal 7 as an output. It is assumed that the input/output characteristics of non-linear circuits 5 and 8 are shown as, for example, at figures (b) and (c). The non-linear circuit 8 has a limiter characteristic and it does not appear when an input level is larger. In other words, the output does not appear when the correlation of the chrominance signal is low because the input of the nonlinear circuit 8 is larger and so the color sagging hardly occurs due to no feedback.

Title: Partial plating device
Inventor: KOBAYASHI MINORU
IPC: C25D5/02
Filed: 1985-04-03
Abstract: PURPOSE:To make possible the plating by high-current density and to speed up plating by heating the rear of a part to be plated in the stage of ejecting a plating liquid to the part to be plated of a material to be worked. CONSTITUTION:The material 1 to be worked is fixed between a mask 2 and a fixing plate 9 and the plating liquid is ejected from an injection nozzle 3. Electricity is conducted to a nichrome wire 7 fixed to an aperture 8 of the plate 9 so that said wire generates heat at the same instant when the plating liquid is ejected. The part 4 to be plated is therefore heated from the rear and the quick heating of the plating liquid arises at the boundary between the part 4 and the plating liquid. The ion migration increases accordingly and the diffused layer of the material 1 is decreased by the local micro-boiling effect, by which the electrical conductivity is remarkably improved. The plating by the high-density current is thus made possible and since the part 4 to be plated is heated over a wide area, the plating is speeded up.
