Title: Method for measuring particle size of austenite crystal
Inventor: MIYAJIMA TAKESHI
IPC: G01N29/11
Filed: 1984-08-31
Abstract: PURPOSE:To make it possible to measure the particle size of an austenite crystal in an extremely simple manner in a non-destructive state, by allowing an ultrasonic wave to be incident to an object to be measured and measuring the attenuation quantity of the reflected ultrasonic wave. CONSTITUTION:An ultrasonic sensor 6 is set to the upper surface of an object 1 to be measured and an ultrasonic flaw detector 10 is operated to allow an ultrasonic wave 7 to be incident to the object 1 to be measured. This incident ultrasonic wave 7 is scattered at the grain boundary of crystal particles on a route and propagates through the object 1 to be measured while loses a part of its energy. Then, the incident ultrasonic wave 7 is reflected from the bottom surface 5 of said object 1 to be measured and again reaches the sensor 6 while repeats scattering at the crystal grain boundary and loses its energy and the reflected ultrasonic wave is displayed on CRT11 as echoes 13, 14 along with a transmission pulse 12. The decibel value of the height differences between the echoes 13, 14 is read and the attenuation constant of the ultrasonic wave is calculated from a specific formula. The calculated attenuation constant is adapted to a specific austenite crystal particle size estimation chart to make it possible to calculate the particle size of the austenite crystal.

Abstract: PURPOSE:To execute the development without an omission even in the case of a latent image moving at a high speed by dividing a toner supply path into plural slots by a separator, and also, constituting them so that the inside surface of the slot is wetted easily by a liquid toner, and the end face of an opening part of the slot opposed to the latent image is scarcely wetted by the liquid toner. CONSTITUTION:An opening part of a supply path of a liquid toner 6 is separated by partition walls 3a, 3b, the inner wall surface of the respective slots is made of a material which is wetted easily by the liquid toner 6, and also, to each slot opening part 4a-4d, a water repellent processing which is scarcely wetted by the liquid toner is performed. Therefore, in a toner supply path end part, plural meniscuses 5a-5c are formed. When an electrostatic latent image approaches the meniscuses 5a-5c in a developing area as the surface of a latent image carrying body moves, electric field strength of a space between both of them increases and a projecting part is formed from the surface of the liquid toner 6, and drawn toward the latent image part. In this case, the projecting part is formed in parallel from plural meniscuses 5a-5c, respectively. In such a way, the development being free from an omission is executed at a high speed.

Inventor: SHIMIZU TORU
IPC: H01L21/316
Filed: 1989-07-14
Abstract: PURPOSE:To prevent a difference in level from being produced between a field region and an active region by a method wherein a resist, an oxide film and a nitride film are etched, under a dry etching condition having no selectivity, until nitrogen cannot be detected. CONSTITUTION:A LOCOS oxide film 1 is formed in a part which is not covered with a LOCOS nitride film 2; a resist 4 is coated in such a way that a surface shape becomes flat. The resist 4, the LOCOS oxide film 1 and the LOCOS nitride film 2 are etched under a dry etching condition having no selectivity until nitrogen cannot be detected. By such a treatment, they are etched while keeping the flat surface shape as coated with the resist; since a layer containing nitrogen does not exist other than the LOCOS nitride film, this etching operation can be finished when the LOCOS nitride film has been etched completely. Thereby, a part between a field region and an active region can be flattened.
