Title: Optical device with grating formed and add/drop filter using the same
Inventor: UETSUKA NAOTO
IPC: G02B6/02
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain a grating which eliminates a ripple and can be approximated to spectral characteristics in an ideal rectangular shape by varying the width of the core of a waveguide. SOLUTION: The width W of the core 11 of the waveguide which has the grating decreases toward a center O according to a function represented as W=W0 -▵W.exp(-Z<2> /S<2> ). In this equation, W0 is the original core width (core width on both sides) of the waveguide, ▵W is the decrease width of the core width, and S is Gaussian type spot size. Then current variation in the equivalent refractive index Neff with a decrease in the core width decreases toward the center according to a Gaussian distribution shown in Figure (b). An average increase in refractive index caused by light irradiation enlarges toward the center as shown in Figure (c). Accordingly, the ▵W shown in the equation is optimized to cancel the average refractive index increase caused by the light irradiation shown in a figure (C).

Title: Steering device for smaller ship
Inventor: OOKUMA SHIYOUZOU
IPC: B63H25/26
Filed: 1980-03-10
Abstract: PURPOSE: To alleviate bend moment applied on an arm due to rocking motions of a ship, by supporting a steering device at the middle part thereof.  
     CONSTITUTION: When a screw thread axis 41 is revolved by a motor operation, a screw thread material 51 moves in the direction of the axis to extend or shorten an arm 5, so that a steering shaft revolves through a ladder arm. Whenever the steering angle surpasses a set range, it gets contact with a limit switch to stop the operation of the motor. During these operations, reactions of the arm 5 extending and shortening are applied to the part of a ginbal structure 6. But this part is supported by a pair of horizontal axis 60, 60 and vertical axis 63, 63 which come to the axis center of the arm 5, so that no bend moment is applied on the arms 4 and 5. And as the weight of a steering device itself is supported by the ginbal structure 6 at the middle part, the bent moment applied to the arms 4, 5 by the weight of itself is small. So rocking motions of the ship, if any, cause no problems.

Filed: 1990-02-14
Abstract: PURPOSE:To enable increasing a speed of response, preventing the uneven density of a printed picture and miniaturizing an apparatus by correcting the pulse number or pulse width of a recorded picture signal on the basis of a parameter information on a voltage drop due to conduction of a thermal head, where recording is performed in a simultaneously progressing manner in recording line units. CONSTITUTION:A plurality of heating resistors D1-Dn, to which recorded picture signals are applied simultaneously, are expressed by the axis of abscissas; and picture densities D corresponding to gradation steps S1-Sn of a picture to be printed, by the axis of ordinates; and regions Zz and Xx express a half-tone picture part and a solid picture part, respectively. When such gradation recording is performed, a voltage drop of DELTAV occurs for each gradation step so that the arithmetic value DELTAV of the voltage drop in each sampling step is compared with a threshold level CL. When the voltage drop is larger than the latter, a correction pulse is applied to a pulse application region in the sampling step or the same region as the pulse application region of a step near to that step. A correction pulse C1 is applied to each recorded picture signal in the step Sn.
