Title: Developing device and developer container
Inventor: MATSUDA KENJI
IPC: G03G15/08
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent developer from spouting out due to the increase of an air pressure in a developer container, by providing a labyrinth seal part on a sealing member. SOLUTION: The device is provided with an end part seal 101 which is brought into press-contact with the circumferential surface of a developing roller, a spout-out preventing sheet 102 which is stuck between the downstream side of the developing roller in the rotating direction and an opening part, in the longitudinal direction of the opening part, and having a free end which comes in contact with the developing roller, and a back seal 104 which is stuck on the developing container and which comes in contact with the rear side of a blade so as to reduce the infiltration of toner to the upper part and the end part of the container. The back seal 104 is constituted of three members, fine gaps are arranged in respective members so as to function as an air path for linking the inside of the developer container with the outside.  The air path has a labyrinth constitution obtained by combining plural straight lines, and the air path is devised so that the developer may not leak outside the developer container when only the any one direction force is applied.

IPC: F16H48/12
Filed: 1995-03-01
Abstract: PURPOSE: To produce a speed-sensitive type differential limit force during running forward and to prevent a differential limit force and an antilock brake system during braking by a method wherein a clutch arranged between a differential mechanism and a differential limit device is engaged during running forward of a vehicle and disengaged during reversing. CONSTITUTION: During running forward, a dog clutch 75 is engaged and a differential limit device 41 is coupled to side gears 55 and 57 for operation to produce a speed-sensitive type differential limit force. During braking in which a differential case 21 is rotated by side gears 55 and 57 on the output sides like when a vehicle is reversed, the engaging thrust force 93 between the side gears 55 and 57 is generated axially outward. Through the engaging thrust force 93, the side gears 55 and 57 are moved outward and the dog clutch 75 is released from engagement. Frictional resistance is generated between a housing 43, the side gear 57, and the differential case 21 through a washer 49 and a disc spring 77 and a gentle torque-sensitive differential limit function is provided.

Title: Original press-contacting device
Inventor: KAWASAKI MINEKO
IPC: G03B27/62
Filed: 1990-02-22
Abstract: PURPOSE:To freely select the opening/closing angle of a pressing plate and to prevent the pressing plate from being closed even if a hand is detached from it by providing a plastic plate fixing the movement of the supporting body of the pressing plate. CONSTITUTION:When the pressing plate 1 is moved to a side to be opened, it is smoothly moved, and the tooth of a gear 3 are caught so that the pressing plate does not move when it is moved in a direction to be closed. In other words, when the pressing plate is about to move in a direction where the pressing plate is closed, the gear 3 is caught and the plastic plate 4 is fixed. When the pressing plate is closed, by imparting the power with the hand, the plastic plate 4 is pulled by the gear 3, and bent, and the pressing plate 1 is closed. Therefore, as the plastic plate 4, a member which endures the weight of the pressing plate 1 and has elasticity so as to be bent when the weight of the pressing plate 1+alpha is imparted is used. Thus, the opening/closing angle of the pressing pate can be freely selected. Even if the hand is erroneously detached, the pressing plate is not powerfully closed, an original is not flied, and a shock is not imparted to a copying machine.

Title: Resist applying method
Inventor: OODOI YUUZOU
IPC: B05D1/40
Filed: 1991-03-08
Abstract: PURPOSE:To improve the uniformity of the thickness of resist film by providing a process which maintains the first speed of revolution for obtaining desired film thickness and, next to the process, another process that increases the first speed of revolution to the higher second speed of revolution. CONSTITUTION:At least the process which maintains the first speed of revolution for obtaining desired film thickness and, next to the process, the other process that increases the first speed of revolution to the higher second speed of revolution are provided. When the first speed of revolution for obtaining the desired film thickness is maintained, a resist 2 rises at the outer edge of a substrate 1. However, when time T1 for maintaining the first speed of revolution is just as long as forming the resist film of specified thickness, a solvent is in a state of nonvolatility because the resist film at the outer edge of the substrate 1 is thick. Accordingly, if the first speed of revolution is increased to the higher second speed of revolution, the thick resist part at the outer edge of the substrate 1 is scattered and the film becomes thin. Thus the uniformity of the thickness of the resist film over the substrate 1 improves.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain an electrochromic element having excellent UV resistance by disposing an electrochromic layer, a pair of electrode layers and a layer of a sealing resin contg. a UV absorbent on a substrate. SOLUTION: This electrochromic element has the electrochromic layer 4, a pair of the electrode layers 2, 3 holding the layer and the layer 5 of the sealing resin contg. the UV absorbent on a substrate 1. Namely, the UV absorbent is incorporated into the sealing resin, by which the UV rays are absorbed into the layer 5 of the sealing resin when the resin is irradiated with the UV rays from the sealing substrate 6 side and, therefore, the quantity of the UV rays to be cast to the electrode layers 2, 3 and the electrochromic layer 4 is decreased and the deterioration of the electrochromic layer 4 by the UV rays is lessened. More particularly when the electrochromic layer 4 has tungsten trioxide, the tungsten trioxide exhibits the phenomenon to be colored by the UV rays, i.e., photochromism.  When the electrochromic layer is irradiated with the UV rays, the layer discolors to blue and in this case, the blue coloration is prevented as well.
