摘要： PROBLEM TO BE SOLVED: To improve a utilizing efficiency of a communication channel and to monitor and immediately before state even if the condition information of a mobile body is impossible to be acquired by storing the information in a portable terminal unit, and then transmitting the information to a monitoring unit. SOLUTION: When condition information indicating an object person's position or operating state can be acquired from a GPS receiver 105 or a body motion sensor 104, a portable terminal unit 100 carried by an object person stores acquired condition information in a memory 10 of the terminal unit. A monitoring unit installed in a monitoring center establishes a communication channel to the unit 100 carried by the monitoring person and requests transmitting of the condition information when a predetermined condition is satisfied such as when a specific time is elapsed or an operator's instruction is input. The unit 100 requested by the transmitting reads the information stored in the memory 102 of the unit 100, and transmits the information to a monitoring unit 300. The unit 300 receiving the transmitted information displays the person's position or operating state obtained from the condition information together with map information on a display unit 305.

摘要： PURPOSE:To obtain an excellent picture by generating a reference voltage being a reproduced waveform resulting from deviding the level between a white level signal and a black level signal at a prescribed rate, comparing the reference voltage and a picture signal outputted from a read sensor so as to output a digital signal subject to distortion correction. CONSTITUTION:A reproduced waveform is generated based on a white level signal reproduced by a white level signal storage reproduction means 1 and a black level signal reproduced by a black level signal storage reproduction means 2. The reproduced waveform results from dividing a level between a white level signal and a black level signal at a prescribed rate and corresponds to a signal when an original (gray original) with a prescribed intermediate reflectance is read. The reproduced waveform is used for the comparison with the picture signal as a reference voltage when an actual original is read and a digital signal is generated depending which of them is larger. Thus, the digital signal whose distortion is corrected is obtained independently of the level of the picture signal of the original, that is, independently of the gray density level.

摘要： PURPOSE:To prevent the lowering in yield, by a method wherein a glaze built-up part is formed by a thick film production process in the same way as that for a partial glaze and thereafter, a thin film production process is started. CONSTITUTION:A partial glaze 2 and a glaze built-up part 3 are formed on a ceramic substrate 1 by printing glass paste to be baked. In that case, though it is necessary that the glaze built-up part 3 is made higher than the partial glaze 2, they are formed by making a printing number of times of the glaze built-up part 3 more than that of the partial glaze 2. Thereafter, a thermal resistor 4, and a conductor 5 are formed by sputtering. Then, they are coated by photo resist 6, and exposure is carried out by photomask 7. Then, develop ment and etching are executed, and a pattern is formed. Since the height of the glaze built-up part 3 is made higher than that of the partial glaze 2, the photomask 7 is in contact with the glaze built-up part 3, and does not contact with the partial glaze 2. Since the partial glaze and the glaze built-up part are formed in this way before the thin film production process, the yield deterio ration can be prevented.

摘要： PURPOSE:To allow the peripheral edge parts of adjacent developed color dots to be overlapped with each other, by a method wherein each of resistors is formed so as to be made narrow from both ends thereof toward the center thereof and the wide parts in the vicinity of both ends of adjacent resistors are partially positioned within a sub-scanning region having a predetermined width. CONSTITUTION:A large number of resistors 1 are arranged in a zigzag pattern in a main scanning direction and adjacent resistors are arranged so that the wide parts 1a of one resistor are allowed to coincide with the narrow parts 1c being the central parts of the other resistor and the narrow parts 1c being the central parts of one resistor are allowed to coincide with the wide parts 1b of the other resistor and one of the wide parts of each resistor enters into each narrow part 1c so as to exceed the line connecting the apexes of the wide parts 1a, 1b of both resistors. Therefore, a large number of the heat generating resistors are arranged to a thermal recording head so that the parts S, S' of both wide parts 1a, 1b are positioned in a sub-scanning area having a width (a). When input energy is increased, dots overlap each other at the peripheral parts thereof and an undeveloped color area is eliminated. As a result, the number of the white stripes or broken characters of an image is reduced to a large extent.
