Title: Developing device
Inventor: OSADA JINICHI
IPC: G03G15/08
Filed: 1986-02-07
Abstract: PURPOSE:To accurately detect the density of toner in a developer by carrying the developer blocked by a doctor in the direction reverse to the carrying direction of the developer carried by a developing roller on the upper position of a developer carrying member. CONSTITUTION:Although the developer agitaged by the rotation of an agitating roller 9 rotated in an arrow (a) direction in a developing tank 8 filled with the developer 3 up to a position (p) is carried by the rotation of a developing roller 4 rotated in an arrow (b) direction, a part of the developer is blocked by the doctor to attain stable development in a developing part 6 and the always constant quantity of developer is carried to the developing part 6. The developer blocked by the doctor 7 is carried to the reverse direction to the carrying direction of the developer carried by the developing roller at the upper part of the developer carrying member 1 by the resiliency of the developer colliding against the doctor 7. The developer 3 carried on the upper part of the member 1 is passed through the toner density sensor 2 side and discharged to the agitating roller 9 arranged on the back of the developing roller 4. Consequently, detecting density can be prevented from the generation of errors.

Abstract: PURPOSE:To uniform whole screen brightness distribution by uniforming the brightness distribution in a vertical direction of a display picture through the use of barrel-shape grid elements, and uniforming the brightness distribution in a horizontal direction through the parallel arrangement of the vertical direction grid elements with variable pitch in the horizontal direction. CONSTITUTION:The vertical direction stripes of three primary colors fluorescent material are repeatedly arranged in a horizontal direction so as to form a fluorescent screen on the back face of a panel, and facing the fluorescent screen, vertical direction grid elements 11a are arranged in parallel in the horizontal direction so as to form a shadow mask structure 7, in which respective grid elements 11a have barrel-shape. The shape of an electron beam passing through opening portion sandwiched between the grids elements 11a is widened at both end portions in a vertical direction, and is narrowed in the center portion, and the vertical direction grid elements are arranged in parallel so that the distances between their central lines are short in the horizontal direction center portion and become longer as positions approach both end portions 10a, 10b in a horizontal direction. Thereby, it is possible to uniform the brightness distributions in both horizontal and vertical directions.

Title: Cassette loading device
Inventor: ITOU NARIHIRO
IPC: G11B15/675
Filed: 1990-02-06
Abstract: PURPOSE:To reduce the cost of the cassette loading device by providing the device with a means for detecting the loading of a cassette holder to a cassette loading position and carrying the cassette holder to its stop position at the time of loading the holder to the cassette loading position by one switch and a means for storing the detected results. CONSTITUTION:When a cassette(CT) 1 is inserted into the cassette holder (HC) 11 and pressed into the device, a driving system is driven and an arm member 14 is rotated in the arrow A direction. The post 11a of the HC 11 is moved along a groove part 12a and a lid 3 is abutted upon a lid opener 13 to push up and open the lid 3. When the CT 1 is loaded to a deck base 17, a switch(SW) 18 is driven to end the loading of the CT 1 and set up a tape traveling enable state. At the time of detecting a stop position moving instruction, the driving system is driven, the member 14 is rotated reversely from the arrow A, the HC 11 is lifted and the SW 18 is turned from ON to OFF to stop the driving system, but the device can hold the current state because of the inertia force of the motor and the hysteresis of the SW 18. Since only the SW 18 is used as the detecting means, the cost price of the device is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent lead wires from being attached to a turning-on circuit board at wrong polarities and, at the same time, to improve the workability of the assembling work of a light source device, by inserting and fixing the turning-on circuit board having asymmetrically bored fixing holes connected with the paired lead wires of a light source into and in the guide groove of the main body of a socket formed on one side from the center axis. SOLUTION: A light source device 1 is formed by inserting and fixing the base-side end section of an LED 4 and a platy turning-on circuit board 5 into and in an inserting hole 3 of a main body 2 of a socket. At the time of inserting the base-side end section of the LED 4 into the hole 3, paired lead wires 4b of the LED 4 are fixed to the asymmetric fixing holes of the board 5 to which contact terminals 11a and 11b are fixed in advance by matching the polarities. At the time of inserting the board 5 into the inserting hole 3, both end sections of the board 5 in the width direction are put and slid in a pair of parallel guide grooves formed in an oppositely faced state at positions which are slightly deviated to one side from the center axis.  When the board 5 is inserted into the hole 3 along the guide grooves, the contact terminals 11a and 11b are arranged on the outside of the main body 2, so that their polarities may be matched to those of electrodes 15a and 15b of a printed board 6.

Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of polish irregularities by performing cleaning with the use of a roll of an elastic body held with a predetermined distance from a disk, in place of a tape. SOLUTION: A disk 2 is chucked at the inner circumference to a spindle 1 and supported rotatably. The rotation of a motor is transmitted to a rotary shaft of a roll 3, whereby the roll 3 is rotated with a predetermined revolution number. The roll 3 is fixed to a slider 4. The slider 4 is connected to surfaces of a base 5 and the disk 2 to be movable in a perpendicular direction and fixed at a specific position. Cleaning is realized by rotating the disk 2 and roll 3 with a predetermined revolution number after a distance between the roll 3 and a face to be cleaned of the disk 2 is secured at a predetermined position. The distance between the roll 3 and the face to be cleaned is determined with a height of foreign articles or protrusions to be removed and physical properties (a modulus of elasticity, etc.), of a roll material being taken into account. The cleaning is realized stably.

Abstract: PURPOSE:To improve fatigue resistance strength of a connection part between a plate spring and an armature, by a method wherein at least one or more welding points among the welding points weld a face conforming the rear end face of the armature to an edge face forming a hole provided to an armature fitting part of the plate spring. CONSTITUTION:A welding point position to which maximum bending moment is applied is transferred onto a face for conforming an edge face forming a hole provided to an arm part of a plate spring 6 to a rear end face of an armature 7 and laser spot welding is carried out at five positions 13a', 13b, 13c, 13d, 13e. At the welding point 13a' where the plate spring 6 is laser-welded to an edge end face of the armature 7, no micro crack 15 occurs near a bending moment side 18 of a border part 16 between the plate spring 6 on which peeling force acts by bending moment and the armature 7. A micro crack constituting a starting cause of fatigue failure can be prevented from occurrence thereby and the fatigue failure resistance of the plate spring is improved. Then, the durability of a wire dot printer head of a spring charge type can be remarkably improved.
