Filed: 1990-01-22
Abstract: PURPOSE:To enable the layout of logic cells where a wiring can easily be made to be obtained in a short time by a method wherein evaluation functions which evaluate the layout of logic cells are optimized on an average. CONSTITUTION:A setting section 1 sets evaluation functions which evaluate the layout of logic cells, the target value of each of the evaluation functions, a layout improvement method which makes the evaluation functions optimal, and a satisfaction level for each of the evaluation functions. A computation section 3 computes a difference between the evaluation function value obtained by evaluating the layout of the logic cells and the target value for each of the evaluation functions, and a selection section 3 selects an layout improvement method which optimizes the evaluation function corresponding to the maximum difference out of the computed differences. A execution section 7 executes the selected layout improvement method, and a resetting section 11 keeps the improved layouts of the logic cells if it is judged that the evaluation function value corresponding to the executed layout improvement method approximates to a target value and the evaluation function values other than the above function value satisfy a satisfaction level value. By this setup, the layout of logic cells where a wiring can be easily made can easily be obtained in a short time.

Filed: 1984-01-23
Abstract: PURPOSE:To prevent a disk from damage by shifting a magnetic head to a track except an effective recording disk after recording and reproduction have been completed in the condition where a magnetic head is floated from a magnetic disk. CONSTITUTION:Two magnetic disks 2 are fixed on a spindle 3 and sealed in a dusttight-type container 1 together with a magnetic head 4.

IPC: H04N1/417
Filed: 1993-01-27
Abstract: PURPOSE:To improve the coding efficiency by connecting a character prediction processing section to a 1-dimensional coder, a photograph prediction processing section to a 2-dimensional coder and selecting an output of the linear coder or an output of the 2-dimensional coder based on the result of prediction. CONSTITUTION:A small block discrimination section 8 reads an unpredicted picture element number from a character unpredicted picture element counter 5 and a photograph unpredicted picture element counter 7 and compares them. When the count of the counter 5 is more than the count of the counter 7, a coder selector 13 selects an output of a 1-dimensional coder 10 and a small block selector 9 selects an output of a 1-block delay memory 6 being an output of the photograph prediction processing section 3. On the other hand, when the count of the counter 7 is more than the count of the counter 5, the selector 13 selects an output of a 2-dimension coder 12 and the selector 9 selects an output of the memory 4 being an output of the character prediction processing section. Then a mode signal addition section 14 adds the result of selection to the coding result as a mode signal. Thus, the coding efficiency is improved.

Title: Forming method of optical waveguide
Inventor: HASEGAWA HIDEKAZU
IPC: G02B6/13
Filed: 1984-01-24
Abstract: PURPOSE:To provide an optical waveguide easily by stacking a thin film which has a higher refractive index than a substrate on which the optical waveguide is formed on the top surface of the substrate, and irradiating the substrate with moving light under a vacuum from above the substrate along a specific track so that the light is focused on the contact surface of the thin film and thus depositing the thin film on the substrate. CONSTITUTION:A laser light source 3 and a condenser lens 6 are provided at the upper part in a container 2 which can be evacuated to a high vacuum, and the glass substrate 4 on which the optical waveguide is expected to be formed is installed at the lower part in the container 2 while the glass thin film 7 having the lower refractive index than the substrate is stacked on the top surface of the substrate 4. Then, the container 2 is evacuated to a high vacuum and the thin film 7 is deposited on the substrate 4 by being irradiated with laser light 5 from the light source 3 along the specific track, thus forming the optical waveguide. In this case, the substrate 4 may be made of plastic, the thin film 7 may use a photopolymerizing compound, and an ultraviolet-ray source is usable instead of the laser light source 3. Thus, the high-reliability optical waveguide is formed easily at low cost with the simple device.
