Title: Thermal transfer printer with gradation
Inventor: TAMARU MUNETAKA
IPC: H04N1/23
Filed: 1985-03-29
Abstract: PURPOSE:To make possible to suppress the irregularity of a transfer ratio to a reduced degree, by dividing the density of an image into a high density part, a half density part and a low density part and driving the half density part by voltage lower than each of voltages driving the other parts. CONSTITUTION:When the power supplied to the picture element electrode of a thermal head is investigated on the basis of the relation of voltage and a pulse width with optical reflection density after the transfer of ink, a high voltage and small pulse width one is reduced in the irregularity of density but has an acute density gradient to the pulse width while a low voltage and large pulse width one has a gentle density gradient and especially has difference in a half density. An image is divided on the basis of density by utilizing these properties and the picture element electrode is driven by driving voltage proper at every division to perform printing. That is, for example, in the relation 3 between power supplied to the picture element electrode and the optical reflection density of a printed dot, the density of the image is divided into a high density part 3a, a half density part 3b and a low density part 3c and the high density part 3a and the low density part 3c are driven by higher voltage and a shorter pulse width as compared with the half density part 3b.

Abstract: PURPOSE:To promote pasivity of a pipe surface and to prevent the production of stress corrosion crack at a U-tube part upon which a residual stress is exerted, by a method wherein a short pass preventing plate and a bent plate are installed at a U- tube part of a heat transfer pipe group. CONSTITUTION:A short pass preventing plate 8 is located at a center of a U-tube part of heat transfer tubes 3 in a state to be connected to partition 4. A bent plate 10, in which a large number of small holes are machined, is coupled to the end part, at a penel 1 side, of the short pass preventing plate 8 so that it crosses the prevention plate 8 at right angles. This prevents the formation of a current staying area at the U-tube part, always feeds fresh air to the surfaces of the heat transfer tubes, and promotes pasivity of the tube surface through the formation of a protection film. The short pass preventing plate 8 supports the U-tube part to improve rigidity and prevent vibration.

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the rupture and the reduction of area of a welded point by moving the arrangements of work rolls before or after the welded point of preceding steel strip and succeeding steel strip passes through the work rolls. SOLUTION: To prevent the edge drops at tip parts in the width direction of the steel strip with the welded point of the preceding steel strip 1 and the succeeding steel strip 2, the arrangements of the work rolls 3 are moved before or after the welded point passes through a pair of upper and lower single- tapered work rolls 3 whose arrangements are freely changeable in the axial direction of the roll. After the welded point passes through the work roll 3, a movement in the axial direction of the work roll is started, and a movement working is completed while the succeeding steel strip 2 passes through. Or the movement in the axial direction of the work roll 3 is started while the preceding steel strip 1 passes through, before the welded point reaches the work roll 3, the movement working is completed.  Consequently, the occurrence of the rupture and the reduction of area of the welded point, caused by the movement of the work roll 3 can be prevented.

Title: Magnetic video recording and reproducing device
Inventor: TAKIMOTO HIROYUKI
IPC: H04N5/783
Filed: 1983-04-14
Abstract: PURPOSE:To obtain a timing signal for switching heads and another timing signal for controlling the tracking of the heads with a simple constitution, by providing a phase signal generating means which generates a phase signal which is used as a reference for switching the heads and a switching signal generating means which generates the switching signal of the heads a prescribed time later after the phase signal. CONSTITUTION:Video signals VS are inputted into a change-over switch SW and alternately supplied to heads H1 and H2 by means of a timing signal TS. In this case, the time constants T2 and T2' of monostable multivibrators MM3 and MM4 are set to several tens microseconds and the time constant T3 of other monostable multivibrators MM5 and MM6 is set to 1-2 horizontal periods, namely, about 60-120musec. Therefore, since the delay time from the detecting timing of a Hall element until a timing signal for obtaining a recording or reproducing area is extremely shortened, the amount of variation of delay times against the output time of fR and fW is reduced to a degree which can be disregarded and, moreover, the positions on a track of the recording area and reproducing area are fixed, resulting in easy adjustment of the vertical position of the heads.

Title: Device for measuring torque
Inventor: TOMIOKA YASUO
IPC: G01L3/14
Filed: 1980-05-20
Abstract: PURPOSE:To decrease the null zone in the measuring device, and to stabilize a zero point in a calibration by eliminating the friction between a sliding contact which is a rotating load when a rotary shaft is rotated and a fixed contact. CONSTITUTION:A moving table 15 is set at a movement base point 13a of a base table 13 by an operating part 14a, and the measurement is started. The torque of a body to be measured 4 is transferred to an engaging part 5. The rotary shaft 12 which forms a unitary body with the engaging part 5 is rotated to the position where the shaft is balanced with the force of a balancing coil spring 6. At this time the sliding contact 7 which is fixed to the rotary shaft 12 is slidden over a passive element 9 of a detecting plate 8 which is relatively located and rotated by the same angle without contact. Since the moving table 15 is located on the movement base point 13a when the rotary shaft 12 is rotated, the sliding contact 7 is not contacted with the resistance element 9 of the detecting plate 8. Therefore, the load is not given to the rotary shaft 12. Then the moving table 15 is moved to the movement end point 13b, the resistance value of the passive element is outputted, and the torque value is measured.

IPC: G01N23/225
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To obtain a processing method in which the distribution of the content of a target element in a sample is found quickly as two-dimensional information by a method wherein a two-dimensional X-ray-intensity distribution obtained by a mapping technique in an EPMA is changed into a quantitative value by correcting a locally different matrix. SOLUTION: From a sample composed of a plurality of oxides, a two-dimensional X-ray-intensity distribution is obtained by a mapping technique in an EPMA. Then, when the two-dimensional X-ray-intensity distribution is changed into a quantitative value, a locally different matrix is corrected. When it is corrected, a matrix correction factor in a two-dimensional oxide system is found in advance regarding the oxide of all existing elements. Then, when the content of a specific oxide in a sample to be analyzed is found, the matrix correction factor in the two-dimensional oxide system of a coexistent oxide with reference to the specific oxide is weighted with the amount of the coexistent oxide so as to obtain a correction factor with reference to the specific oxide.  Thereby, by performing a quantitative computing operation, the distribution of the content of a target element in the sample can be found quickly as two-dimensional information.
