Inventor: WATANABE YOICHIRO
IPC: G03G5/02
Filed: 1985-12-27
Abstract: PURPOSE:To execute optical storage in a short period to prevent the degradation in reproducibility of an original picture due to over-exposure by storing optically the original picture on a photosensitive body and developing its electrostatic latent image with a toner and transferring the developed image to a recording paper and repeating these processes. CONSTITUTION:A surface 14 of a photosensitive body 10 is uniformly electrified negatively, and the original picture is exposed to form the electrostatic latent image, and the image is developed with the toner. Thus, the image corresponding to the original picture is stored optically on the photosensitive body. Next, the photosensitive body 10 is subjected to the transfer process, and the toner stuck to the electrostatic latent image is transferred to a recording paper 9 to obtain a copy picture. Thereafter, the photosensitive body 10 is subjected to the cleaning process. These electrifying process, developing process, transfer process, and cleaning process are repeated, and a toner image corresponding to an original picture is formed on the recording paper 9 each time when the photosensitive body 10 is subjected to these processes.

Title: Ni-base alloy for build-up welding
Inventor: FUJITA SENJI
IPC: B23K35/30
Filed: 1992-11-11
Abstract: PURPOSE:To provide the Mo-contg. Ni-base alloy for buildup welding which does not generate crack in the case of execution of build-up welding, has a good melt flow property and does not generate a build-up defective part. CONSTITUTION:This Ni-base alloy powder for plasma powder welding corresponds to 'Hastelloy(R)' adjusted to the total content of Si and Mn to >=0.1wt.% by incorporating about 15wt.% Mo and about 15wt.% Cr into the alloy, suppressing the content of S to <=0.003wt.% and further adding Si to the alloy. Since the S as the impurity is suppressed to a low ratio, the precipitation of MoS2 at the grain boundary is prevented and the surface crack of the build-up part is eliminated when the build-up part solidifies. The flow property is improved by specifying (Si-Mn) >=0.1wt.% and, therefore, the generation of a dent insufficient in build-up is obviated.

Abstract: PURPOSE:To prevent that the strain of a plate member exerts some effect on the detection accuracy of a load cell, by allowing the other end of a mount member to loosely pierce through the through-hole provided to other plate member by drilling and forming the load cell mount part to the other end of the mount member. CONSTITUTION:A crosshead 20 extends in the direction crossing a load shaft at aright angle and has an upper plate 21 and a lower plate 22 opposed to each other and the lower end of a cylindrical load cell mount stand 31 is fixed to the lower plate 22. The mount plate 31 extends upwardly through the circular through-hole 21a provided to the upper plate 21 and a load cell 3 is screwed in the load cell mount part at the upper end thereof. The diameter of the through-hole 21a of the upper plate 21 is made larger than that of the mount stand 31 and, therefore, the mount stand 31 is loosely engaged with the through- hole 21a. Whereupon, even when the bending is generated by the load acting on the load cell during a test, the load cell 3 receives no effect.
