IPC: G11B20/18
Filed: 1989-11-16
Abstract: PURPOSE:To effectively detect even a small defect and to prevent such an accident that reproducing is infeasible by providing a means for forming a window and a means for changing a period of the window to be formed. CONSTITUTION:A 1st discriminating circuit 15 and a 2nd discriminating circuit 16 are the circuits for detecting a rising edge of a binary data to be outputted from a binarization circuit 8 in their respective prescribed window periods, and an output of the discriminating circuit selected by a selector 17 is supplied to a synchronizing pattern detecting circuit 11 and a signal circuit 12. The 1st discriminating circuit 15 is set as, for instance, a window period of + or -1/2t, while the 2nd discriminating circuit 16 is set as half of the above as + or -1/4t. Consequently, the window can optionally be changed, and when the reproducing is performed by narrowing the window, the discriminating condition can be so severe that an error factor is easily found, and on the contrary, when the reproducing is performed by widening the window, an error rate can be diminished. By this method, an error generating factor on a recording medium is detected in its early stages, thus preventing the situation of infeasibility of reproducing in the future from turning out.

Title: Control device for internal combustion engine
Inventor: NAKANO KAZUMI
IPC: F02B77/08
Filed: 1993-11-29
Abstract: PURPOSE:To accurately carry out various sorts of adaptive control although the cooling water temperature of an internal combustion engine is detected by means of a water temperature sensor having rough accuracy. CONSTITUTION:A thermostat 50 and a water temperature sensor 4 are arranged in a thermostat case 41 integrated with the cooling water outlet side of an internal combustion engine 40, and cooling water temperature is detected with the water temperature sensor 4. When the cooling water temperature of the engine 40 rises and reaches the decided temperature, the thermostat 50 makes the water passage from the close state to the open state so as to freely pass cooling water. Then when the cooling water temperature begins to lower and reaches the decided temperature, the thermostat 50 makes the water passage from the open state to the close state, so as to control the cooling water temperature in the engine 40 in a decided temperature range. By utilizing the accurate characteristic of the thermostat 50 against the cooling water temperature, deviation of the detected temperature of the water temperature sensor 4 and the actual cooling water temperature is corrected, and hence the cheap sensor can be adopted.

Title: Large float supported by mutiple rows of floats
Inventor: OTA MAKOTO
IPC: B63B39/00
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce vertical displacement and direct stress of a large float, by providing many supporting floats hanging from the bottom surface of a deck, and setting the ratio between a typical value D of these supporting floats and a distance Ls between the centers of the supporting floats placed at the bottom surface of the deck so as to become a specific value. SOLUTION: Supporting floats 2 are structured so as to hang from the bottom surface of a large float 1, and horizontally arranged in a grid pattern or in a slanting grid pattern. In a case where the cross sectional shape of each supporting float 2 is a circle, the diameter thereof is regarded as a typical diameter D. In a case where the cross sectional shape of each supporting float 2 is a polygon, the diameter of a circle with an area equal to the cross sectional area is regarded as a typical diameter D. The ratio D/Ls between this typical diameter D and a distance Ls between the centers of the supporting floats 2 is determined based on the maximum height of waves generated at a site where the large float 1 is placed.  For example, in the case of evaluating at a stress λmax=8 g/mm2, D/Ls is set to 0.84 or below in the case of placing the large float 1 in an area sea where the maximum wave height is approximately 2 m, 0.58 or below in the case of approximately 3 m, and 0.32 in the case of approximately 7 m.

IPC: G02B5/20
Filed: 1987-11-27
Abstract: PURPOSE:To prevent crack generation in a main pattern of a color filter due to heat-treatment by elevating the temp. of a color filter slowly after forming the color filter on a base plate from near room temp. and executing drying thereafter. CONSTITUTION:Gelatin is coated on a glass base plate and the coated product is developed and patterned after exposing through a photomask. The gelatin layer is dyed and then a color mixture preventive layer is superposed thereon. The whole part of the base plat is then laid in an atmosphere at room temp. or 40 deg.C, and the temp. is elevated to 150-180 deg.C with 0.5-2 deg.C/min heating rate, then held for an appropriate time as it is. By this constitution, generation of crack in a main pattern of a color filter during heat-treatment is retarded. Moreover, since the final temp. is arranged to be at high temp., discoloration of the filter in the succeeding stage of pasting of the filter to a solid image pickup element due to heat-treatment is also prevented.
