IPC: G01L5/00
Filed: 1987-11-30
Abstract: PURPOSE:To measure always exact development pressure with good accuracy regardless of a change in ambient temp. by measuring the pressure to be loaded on a measuring element by the deflection of a thin film which comes into contact with a magnetic brush by a detecting means, then measuring the load to be loaded on the measuring element in a no-load state. CONSTITUTION:A small hole 2 is provided on the peripheral face of a casing 1 and the thin film 3 covering at least the small hole 2 is provided. The measuring element 4 constituted in such a manner that one end thereof is connected to a load detecting means 5 and the other end comes into contact with the thin film 3 through the inside of the small hole 2 is provided. The pressure is measured by the detecting means 5 under the actual developing conditions, i.e., while a sleeve 11 for carrying a developer is under rotation and the magnetic brush 12 is held in contact with a prescribed drum. The sleeve 11 is then detached immediately from the drum and the pressure is measured in the state of the zero pressure. The difference between the two pressures is calculated as the development pressure. The influence by a temp. change, i.e., the fluctuation in the zero level is thereby decreased to a negligible level and the exact development pressure is calculated.

Abstract: PURPOSE:To obtain a long life bit for which abrasion resistance is imparted to a shank part as well as to a cutting blade part of a drill bit body, and toughness to the bit body by hardening the entire bit body to a certain degree through carburization, and by connecting an ultra-hard alloy to the cutting blade part, while quenching the cutting blade part as well as the shank part. CONSTITUTION:After a drill bit body 1 made of iron steel material is carburized, it is quenched during hot bathing, and the surface hardness of the body 1 is defined as Hv350-500. An ultra hard chip 2 is brazed to a cutting blade part 3 using a furnace that can partially heat, such as high frequency heating device, while a shank part 5 is quenched after having been heated, and the surface hardness of the cutting blade part 3 and of the shank part 5 is defined as Hv600-750, and the depth of a hardened layer not less than 1.0mm. By defining the surface hardness of the body 1 quenched in the hot bath, as Hv350-500, toughness is imparted to the body 1, and the folding loss at the time of correcting the deformation after heat treatment, as well as at the time of being used, is prevented. When it is not more than Hv350, it is too soft to be actually used, whereas, when it is not less than Hv500, it is too hard to keep toughness, in which case, folding loss easily occurs at the time of correcting the deformation after heat treatment, as well as the time of being used.
