Patent number: 6757155Abstract: A case for housing an electronic circuit board having a case body formed with an opening and a sealing member for sealing the opening, wherein one of the case body and the sealing member is formed with one fastening member composed of an elastically deformable leg and a projection continuous therewith for enabling attachment of the sealing member to the case body by engagement of the fastening member with a prescribed region of the other. The projection is continuous with the leg and has a first surface formed to contact the prescribed region at a prescribe angle and a second surface continuous with the first surface and formed parallel to the prescribed region. With this, molding error can be tolerated and stress owing to volumetric variation produced by temperature change or to vibration can be readily coped with. Moreover, it is possible to prevent release of the engagement of the projection with the prescribed region, and thus to prevent separation of the sealing member from the case body.Type: GrantFiled: February 5, 2003Date of Patent: June 29, 2004Assignee: Keihin CorporationInventors: Tatsuo Koike, Mitsuhiro Ito

Publication number: 20040022551Abstract: A printing apparatus can reduce wasted power consumption, and prolong the life of an image forming section and fixing pressurizing rollers. It includes a printer control unit including a video controller and engine controller. According to a print reservation from the video controller, the engine controller controls a paper transport mechanism such as feed rollers, transport rollers and lifters, thereby feeding paper from a paper inlet designated by a printing condition. The engine controller controls a laser scanner unit to transfer a formed image to a sheet with a high voltage unit, and fixes it by a fixing assembly. It controls the paper transport mechanism to output the paper to the paper outlet designated by the printing condition. The image forming section and fixing pressurizing rollers are individually rotatable. Their rotation is stoppable individually without interference in a time from printing the first side to reversing and refeeding the paper.Type: ApplicationFiled: July 24, 2003Publication date: February 5, 2004Applicant: Canon Kabushiki KaishaInventors: Mitsuhiro Ito, Hiroaki Sakai

Publication number: 20040005159Abstract: This invention provides an image forming apparatus where the useful life of the image carrier does not become significantly short. This system has a charging unit, a charge voltage loading unit, an exposure unit, a development unit, an image transfer unit and a control unit, wherein, when the transport interval of the plural recording materials is shorter than a predetermined time the AC charge voltage applied to the image carrier during the transport interval being a first AC charge voltage, and when the transport interval is longer than the predetermined time the ac charge voltage applied to the image carrier during the transport interval being a second AC charge voltage, the control unit makes the current running in the charging unit to which the second charge voltage is applied lower than the current running in the charging unit to which the first AC charge voltage is applied.Type: ApplicationFiled: July 1, 2003Publication date: January 8, 2004Inventors: Mitsuhiro Ito, Hiroaki Sakai

Publication number: 20030147217Abstract: In a case for housing an electronic circuit board, the opening edge of the case body is formed with a prescribed distance below the board mounting surface. The board is fastened on the mount of the case body with the fastening means. The case body is then inverted and is placed over a rising coating bath, and then the coating bath is raised close to the opening edge such that the board is dipped in the coating liquid and is coated. By this, application of the coating liquid to prescribed regions constituting coating-prohibited regions of the case body can be prevented. Cost can therefore be kept down and complication of the processing steps prevented because no masking of the case body is necessary. Moreover, the reliability of the electronic circuit unit can be enhanced and the need for a jib is eliminated. This helps to avoid complication of the fabrication process and makes another contribution to cost control.Type: ApplicationFiled: February 5, 2003Publication date: August 7, 2003Applicant: KEIHIN CORPORATIONInventors: Tatsuo Koike, Mitsuhiro Ito

Publication number: 20030147228Abstract: A fastening member for an electronic circuit board having an elastically deformable leg formed in a case for housing the electronic circuit board and a projection formed continuous with the leg to be engaged with the electronic circuit board so as to fasten the electronic circuit board on a prescribed mounting surface in the case. In the member, the projection is engaged with the electronic circuit board such that a prescribed angle is formed between a surface of the projection contacting the electronic circuit board, when the electronic circuit board is fastened on the mounting surface in the case. With this, since the tangent between the board contact surface and the electronic circuit board is variable within the range of the board contact surface, molding error can be tolerated (absorbed) and volumetric variation produced by temperature change can be readily coped with.Type: ApplicationFiled: February 5, 2003Publication date: August 7, 2003Applicant: KEIHIN CORPORATIONInventors: Tatsuo Koike, Mitsuhiro Ito
