Filed: 1979-11-20
Abstract: PURPOSE: To prevent welding cracks and heat treatment cracks to produce a welded joint which can be used as the joint of a heat-proof material sufficiently, by adding a prescribed quantity of Ce to the thin plate of IN738 of the Ni base alloy to subject it to electron beam welding.  
     CONSTITUTION: After Ce is added to the thin plate of IN738 of the Ni base alloy, which is developed as a heat-proof material, by the quantity indicated by the expression, a joint is produced by electron beam welding. As the result, by adding a proper quantity of Ce to the weld metal, electron beam welding crack sensitivity can be lowered, and the welding limit heat quantity can be enhanced, and further, reheating crack sensitivity can be lowered. Since welding of IN738 which was impossible conventionally is possible and it can be used as the heat-proof joint, heat- proof parts can be produced easily.

Title: Continuous casting method
Inventor: YAMANAKA AKIHIRO
IPC: B22D11/041
Filed: 1995-06-16
Abstract: PURPOSE: To produce a cast slab having little center segregation and center porosity by discharging non-solidified remaining molten steel at the part of a specific value or higher of the vertical height, rolling the cast slab surface and press-sticking a discharged interface of the non-solidified remaining molten steel. CONSTITUTION: The vertical height H at the part, in which a solid phase ratio at the central part of the cast slab 8 is not exceeded to 0.3, is kept so as to become >=1.5m height from the molten steel surface level in a mold 1 and the cast slab 8 is continuously cast and drawn upward as an arc state. Then, the non-solidified remaining molten steel 11 at the part having >=1.5m vertical height H is discharged with a gravity. The cast slab 8 is rolled with rolling reduction rolls 5 arranged just after or after discharging to press stick the discharged interface of the non-solidified remaining molten steel developing a cavity 12. In the case the solid phase ratio exceeds 0.3, an apparent viscous resistance becomes large and the fluid discharge of the molten steel only with the gravity becomes difficult. The upper limit of the desirable vertical height is about 2.5m.  In such a way, the continuous cast slab of the steel having little center segregation and center porosity can be cast.

Abstract: PURPOSE: To solve the problem of the uneven coating density as well as to improve the quality of the luminous screen by securing an inversion between the rotary direction for the processes from the injection of the sensitive slurry containing the fluorescent substance through the high-speed shake-off of the slurry and the rotary direction of the drying process after the shake-off process.  
     CONSTITUTION: In the production of the color cathode-ray tube luminous screen, the processes 1W20 are applied to front panel grass 21. Starting at slurry injection process 3, processes 4 and 5 are carried out while panel glass 21 is turned slowly. After this, the high-speed rotations are given in the opposite direction to the hitherto rotations, and coating density adjustment 6 is given by shaking off the etxra amount of the slurry. Drying process 7 after the high-speed shake-off is performed in the opposite rotations to process 6 and with the revolution number of less than 1/3 the high-speed shake-off revolution number. In this way, the overcoating and undercoating are offset to solve the problem of uneven coating density at the area around glass 21, thus improving greatly the luminous uniformity of the luminous screen.

Abstract: PURPOSE: To conduct the carriage return at a desired place with a simple arrangement by a method wherein a printing instruction at the time of selection of a specified symbol on a type wheel is used to release the carriage from a shift means and to return the carriage to the initial position, in a serial printer.  
     CONSTITUTION: A carriage driving gear 52 at the lower portion of a carriage 3 is engaged with a rack 8, and the rotation of the gear 52 results in a carriage shift. After the completion of the printing at a desired number of places, an operation instructing coil 38 is energized when a blank (corresponding to the size of one character) provided on the type wheel comes to the printing position, whereby a clutch 22 is engaged and the rotation of a motor is transmitted to an up-shift driving gear 32. At this time, although the printing is not conducted since the printing position is blank, a paper feed lever 47 rotates to rotate a rack driving lever 59, thereby releasing the engagement between the rack 8 and the gear 52. Accordingly, the carriage 3 is returned to its initial position by the force of a spring.

IPC: G01T1/17
Filed: 1989-06-14
Abstract: PURPOSE:To measure the dose equivalent of a 1cm-deep part by outputting a detection signal as a voltage pulse having the peak value corresponding to the energy of the radiation incident to a semiconductor radiation detection element. CONSTITUTION:A quality correction filter 13 and a semiconductor radiation detection element 1 are provided so that radiation 4 transmits through the filter 13 to be incident to the radiation incident surface 1a of the element 1. A radiation detection part 17 outputs a detection signal 3a as a voltage pulse having the peak value corresponding to the energy of the radiation 4 incident to the element 1. A peak discriminator 15 discriminates the peak of the signal 3a on a predetermined peak discrimination level and outputs the unit pulse corresponding to the discrimination result. This unit pulse is counted to measure the dose equivalent of a 1cm-deep part. By combining the voltage value of a peak discrimination level with the relation (shield rate characteristic) between the radiation shield rate and radiation energy in the filter 13, the quality characteristics of the apparatus can be made extremely approximate to reference quality characteristics.
