Publication number: 20140055943Abstract: A metal shock absorber, an assembly of a metal shock absorber and a media recording unit, and a media recording device are provided. The metal shock absorber has a pair of horizontal portions, a perpendicular portion connected between the horizontal portions, and a pair of limiting portions. Each of the horizontal portions has a first arcuate protrusion protruding towards another first arcuate protrusion. The perpendicular portion is perpendicularly connected between the pair of horizontal portions, and has an assembling arm. The limiting portions are disposed at opposite sides of the perpendicular portion that are not connected with the horizontal portions. Since the thickness, the tolerance and costs of the metal shock absorber are less than those of the conventional rubber shock absorber, the assembly of the metal shock absorber with the media recording unit has a favorable assembly reliability, and therefore costs of the recording device are effectively lowered.Type: ApplicationFiled: March 15, 2013Publication date: February 27, 2014Applicants: Kinpo Electronics, Inc., Cal-Comp Electronics & Communications Company LimitedInventors: Hung-Wei Chang, Yih-Her Lin

Patent number: 8148833Abstract: An on-road energy conversion and vibration absorber apparatus receives the kinetic energy from moving vehicles and pedestrians when being weighed down, and converts the received kinetic energy into a potential energy using a restorable elastic element compressing a fluid thereby storing the potential energy in a pressure chamber, and then conducting the pressurized fluid to pass though a check valve along a conduit and drive a vane wheel by releasing its potential energy. The vane wheel in turn drives a generator to generate electric energy, and the vibration of the vehicles is alleviated by cushion effect provided by the apparatus.Type: GrantFiled: May 18, 2011Date of Patent: April 3, 2012Inventors: Hung-Wei Chang, Chih-Yang Lee

Patent number: 7926778Abstract: A support having a transmission mechanism using a thin connecting piece includes a support base body, a transmission plate, a supporting plate and at least one thin connecting piece. The support base body has a base and brackets extending upwardly from the base. The distal end of the bracket is provided with a fixing sleeve. One end of the transmission plate is pivotally connected to the bracket. The supporting plate connected to the other end of the transmission plate. The supporting plate is provided with pivoting sleeves. The thin connecting piece is disposed on the transmission plate. Via this arrangement, the supporting plate can be kept vertical in synchronization with the swinging of the transmission plate. Thereby saving the space greatly and reducing the whole volume occupied by the support and peripheral elements. In this way, the assembling process is simplified, the productivity is increased, and the cost is reduced.Type: GrantFiled: February 25, 2008Date of Patent: April 19, 2011Assignee: Syncmold Enterprise Corp.Inventors: Ching-Hui Yen, Chun-Lung Chen, Hung-Wei Chang
