Abstract: PURPOSE: To realize accurate prediction and formation of a high strength, high toughness welding material by predicting the components of welding material based on the sum of elements of the amount of dilution from a mother material, the amount of supply from a wire, and the amount of reaction between the welding metal and a slag.

Subsequently, the strength and toughness 13 of the welding metal are predicted while taking account of the thickness of plate and heat input. When the predicted value does not satisfy a target value, similar calculation is carried out under different conditions and similar operation is repeated until a welding metal satisfying a target performance is obtained.  In principle, following relationship is satisfied; welding metal component = amount of dilution from mother material + amount of supply from wire + amount of reaction between welding metal and slag.

Abstract: PURPOSE:To obtain desirable conductivity without harming light transmittance and enable action with low driving voltage by containing pigments with a conductive member coupled to the surface thereof by a coupling agent. CONSTITUTION:An electrodeposited color filter 41 contains pigments with a conductive member 21 coupled to the surface thereof by a coupling agent.

Both conductivity and high light transmittance can be thus obtained easily, and also the light transmittance at each place is made uniform. In addition, the capacity between electrodes can be sufficiently reduced, and driving can be performed with low driving voltage.

Filed: 1992-09-24
Abstract: PURPOSE:To precisely and quickly transmit various informations for moving area of a moving body such as a car to a player. CONSTITUTION:A coordinate converting processing device 111 reads the information for the form of a course map stored in a polygon data memory 112, and conducts coordinate conversion, on the basis of the position of a player car from a polygon parameter memory 110 and its direction, regularly with the upper part of the player car as a visual point. The information of the coordinate-converted course map is transmitted to a polygon paint device 113, whereby the course map is displayed over the main image of a game. Namely, the miniature of the course is displayed together with the symbol of the player car. Since the coordinate conversion is performed regularly with a fixed upper part of the player car as the visual point, the player car is fixed, while the course map is relatively moved along the symbol of the player car. The display of the course map is changed not only by the change of the position of the player car but also by the change of the angle.

Filed: 1989-10-30
Abstract: PURPOSE:To improve the measurement precision without being affected by the precision of a mark by performing main measurement by the measuring system and measuring the difference between each measure reference distance and mark intervals in the encoder system. CONSTITUTION:A long-sized material 1 marked at mark intervals MS approximately corresponding to a measure reference distance S in the lengthwise direction is measured. In such a case, first and second sensors 3 and 4 are installed on the movement path of the long-sized material 1 so that the interval of detection points is equal to the measure reference distance S. With respect to an encoder 13, an encoder wheel 13A is brought into contact with the surface of the long-sized material 1 and is rotated to output an encoder pulse signal, thus measuring the length of the long-sized material. This encoder pulse signal is used to measure a difference Ci between the measure reference distance S and mark intervals MS, and one counting at each time of mark detection of the second sensor 4 is repeated to perform measurement by the measuring system. Thus, the measured value of the measuring system is corrected with the measured value Ci of the encoder system to obtain length L of the long-sized material 10.
