Title: Production of high toughness steel
Inventor: SEKINE HIROSHI
IPC: C21D8/00
Filed: 1982-07-23
Abstract: PURPOSE:To produce stably and easily steel having excellent toughness by specifying the crystal grain size of austenite prior to rolling and the rolling conditions in the temp. ranges for recrystallization and non-recrystallization. CONSTITUTION:Steel having a general component compsn. is heated to the temp. at which fine grains of #5 austenitic grain size in ATM standard or above are formed. Such steel is cooled at the rate higher than natural cooling without rolling in the recrystallization temp. range for austenite or is subjected to light rolling of about 50% draft and is cooled at the rate higher than natural cooling to prevent the formation of the coarse grains of the crystal. The steel is then rolled at a high draft exceeding 50% in order to provide toughness. The steel is further air-cooled or is forcibly cooled by using a refrigerant such as water (moreferably at about 0.3-5m<3>/min.m<2>), gas or the like in part or the whole in the cooling stage in order to prevent the growth of the crystal grains during cooling.

Title: Construction of image-sensing optical system of optical distance detecting apparatus
Inventor: IDESAWA MASANORI
IPC: G01B11/00
Filed: 1987-05-26
Abstract: PURPOSE:To improve a characteristic of distance detection to be excellent in linearity, by a construction wherein the direction of projection of a light beam is vertical equivalently to an image-sensing lens or the like. CONSTITUTION:The title system is constructed so that the optical axis AL of an image-sensing lens L is vertical to the direction of projection of a light beam B. When an object O moves, a spot T of brilliance of the beam B is shifted only in the vertical direction to the optical axis AL, and therefore the distance of the spot T of brilliance to the lens L in the direction of the optical axis is not varied. Accordingly, imaging positions of sots I and I' of brilliance in the direction of the optical axis of the image-sensing lens are not varied either, and these spots are imaged on a plane located at a prescribed distance to the lens L on the opposite side of the spot T of brilliance. In an image position detecting element P disposed on said plane, therefore, positions of the spots of brilliance found in an optimum imaged state can be detected invariably. In addition, the ratio between the distance from the optical axis AL to spots T and T' of brilliance and the distance from the optical axis AL to the images of the spots T and T' of brilliance in such an imaging system as the above is equal to the ratio between a distance (fixed) in the direction of the optical axis from the nodal point on the object side of the lens L to the spot T of brilliance and a similar distance to the nodal point thereof on the side of the image of the image-sensing lens, and thus said ratio is fixed invariably. Accordingly, a linear relationship is established between the distance of the object in the direction of projection of the beam and the position whereat an image of the spot of brilliance is detected by the element P.

Title: Magnetic powder dispersed type microcarrier
Inventor: KASUYA RIYUUHEI
IPC: G03G9/08
Filed: 1984-06-25
Abstract: PURPOSE:To enhance fluidity in spite of small diameters, and to enable a visible image high in image quality to be formed for a long period by incorporating the mixture of a fluidity enhancing agent and a carrier powder specified in particle diameter contg. a fine magnetic powder dispersed into it in a binder resin with stirring. CONSTITUTION:The stirred mixture of the carrier powder formed by dispersing the fine magnetic powder having an average particle diameter of 10-50mum into the binder resin and the fluidity enhancer are used. Such a carrier is composed of the carrier particles and said enhancer, such as fine inorg. particles attached to the surfaces of the carrier particles, and it is superior in fluidity in spite of small diameter. Accordingly, toner concn. can be raised and its allowance can be enlarged, and high-density visible images can be obtained stably. A magnetic brush is formed delicately and softly, and sharpness and gradation of an image can be improved. When an oscillating electric field system is used, a jumping effect can be ensured and fog can be prevented. Since it is unnecessary to add a fluidity enhancer to the toner, deterioration of toner electrification controllability, and damge of a latent image bearing body, etc., can be prevented, and cleaning performance can be improved.

Abstract: PURPOSE:To prevent the deterioration in recording quality by controlling the quantity of the electrostatic charge to be applied to a photosensitive body by the electric current flowing via a developer between the photosensitive body on which an electrostatic latent image is not formed and a developing section. CONSTITUTION:A recorder is in the state in which exposing by an exposing section 4 is not executed, i.e., the state in which the electrostatic latent image is not formed on the photosensitive body 1 during the discharge of paper.

The current to be detected by a detector 91 is so controlled as to attain the reference value by predetermining such current as the reference value. The deterioration in the recording quality by the environmental change is thereby prevented.
