Title: Developing device
Inventor: HOSOYA MASAHIRO
IPC: G03G15/08
Filed: 1983-09-30
Abstract: PURPOSE:To perform development without density uneveness by making the surface of a movable developer carrier rugged and bringing a flexible coating member into contact with the surface, separting its downstream-side end part from the carrier, and passing nonmagnetic signal-component toner between them during the period. CONSTITUTION:The nonmagnetic toner 17 is sent out of the bottom part of a hopper 16 to the developer carrier 11. The surface of the developer carrier 11 is made finely rugged by a sand blast, etc., the coating member 14 made of an elastic body, e.g. urethane rubber blade is brought into contact with the rugged surface, and its downstream-side front end part 14' is separated from the rugged surface. The carrier 11 is applied with a bias voltage and the toner 17 is applied over the surface of the carrier to uniform thickness to form a developed image having no density uneveness on the surface of the image holder 15. Consequently, uniform density is obtained by single-component development using only the nonmagnetic toner and the device is reduced in size and weight.

Abstract: PURPOSE:To enable the detection of the location and size of a damage in the coated layer of an underground buried metal pipe provided therewith, by connecting a DC power source between the underground buried metal pipe and the soil while a magnetic detection element runs through the pipe. CONSTITUTION:An internal travelling device 3 runs through a metal pipe 1 buried in soil 2. The device 3 is provided with magnetic detection elements S (S1-S4) such as Hall element and lead switch in the circumferential direction of the body 4 and the outputs thereof are applied to a measuring circuit 5 to record 6. Unless any damage exists in a coated layer, the distribution of the density of current flowing through the metal pipe 1 is so uniform that no magnetic field is generated in the pipe and the elements S will not detect a magnetic field. When the coated layer is damaged, current with uneven density flows circumferentially to the affected point and a magnetic field is generated in the pipe near the area large in the current density. The intensity of the magnetic field corresponds to the value of current, that is, the size of the damage. The magnetic detection elements S detect the magnetic field thereby enabling the detection of the damage to the coated layer.

Filed: 1983-09-30
Abstract: PURPOSE:To obtain a controller capable of stably operating even in a low speed range by detecting the power factor of the output of an inverter and correcting the set voltage value by a detection signal.

Abstract: PROBLEM TO BE SOLVED: To attain high capacity, high resolution and color scanning for both a reflection and a transparent original document by arranging a lighting source between a reflecting object focal face and a transparent object support face and selecting the transparent or the reflecting object focal face with a mirror in a scanning carriage. SOLUTION: An optical system for a scanning carriage has functions of selection of an object focal face, determination of a magnification, and folding of an optical path.
