Patent number: 11966628Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.Type: GrantFiled: June 2, 2022Date of Patent: April 23, 2024Assignee: MACRONIX INTERNATIONAL CO., LTD.Inventors: Wei-Chen Wang, Han-Wen Hu, Yung-Chun Li, Huai-Mu Wang, Chien-Chung Ho, Yuan-Hao Chang, Tei-Wei Kuo

Patent number: 6710240Abstract: The present invention provides a register incorporating a toggle-joint mechanism between open and closed position, which is configured to an outlet of a fan, including: a base portion, having a first pivoted joint and a second pivoted joint respectively disposed on two ends and a third pivoted joint disposed between the first pivoted joint and the second pivoted joint, wherein a lock portion is disposed on the base portion; two air guide plates, each of them having a recess on its corresponding side for engaging each other, wherein each of the air guide plates has a pivoted axis respectively disposed at two edges of one end. By the pivoted axis, two air guide plates are pivotally connected with the first pivoted joint, the second pivoted joint and the third pivoted joint. Therefore, the air guide plates are easy to be pivotally connected on the base portion and the base portion is easy to configure to the outlet of the fan.Type: GrantFiled: July 14, 2003Date of Patent: March 23, 2004Assignee: Datech Technology Co., Ltd.Inventors: Jin-Shian Chen, Hsu-Jung Lin, Chien-Chung Li

Patent number: 6565319Abstract: A fan having stable pre-loading device includes a stator, at least one bearing, a rotor having a blade structure, a shaft and a rigid spacer. Among these, the bearing is formed in the space of the stator. One terminal of the shaft is coupled to the stator. The elastic device is formed on the bearing. The rigid spacer is formed on and thus compresses the elastic device. Another terminal of the shaft passing the rigid spacer as well as the elastic device is coupled to the inner ring of the bearing.Type: GrantFiled: August 9, 2001Date of Patent: May 20, 2003Assignee: Delta Electronics Inc.Inventor: Chien-Chung Li

Patent number: 6565316Abstract: An adjustable and stable pre-loading device equipped fan includes a stator, a first rigid spacer, a first bearing, an elastic device, a second bearing, a second rigid spacer, a rotor and a shaft. Among these, the stator includes a receptacle. The first bearing is formed on the first rigid spacer in the receptacle. The elastic device is formed in the receptacle and further on the first bearing. The second rigid spacer is formed on the second bearing on the elastic device. The rotor is coupled to the stator and has a blade structure. The first rigid spacer compresses the elastic device by means of the first bearing. The second rigid spacer compresses the elastic device by means of the second bearing. The distance between the first rigid spacer and the second rigid spacer is adjustable, thereby altering pre-loading applied on the first bearing and the second bearing.Type: GrantFiled: August 9, 2001Date of Patent: May 20, 2003Assignee: Delta Electronics Inc.Inventor: Chien-Chung Li

Publication number: 20020171687Abstract: A computer has a monitor and a processor. An interface system has a plurality of target data sets, at least one relation data set, a display program, a selection program, and an application program. In the plurality of target data sets, each target data set has an ID (identification) of a target. In the relation data sets, each relation data set has two IDs of two corresponding targets and a relation attribute of the two targets. The display program is used to display the plurality of target data sets and the relation data sets on the monitor in a relation graph format. Each target data set is displayed as an icon in the relation graph, and each relation data set is displayed in a linking graph format between the two icons corresponding to the two targets of the relation data set. The selection program is provided for a user to select the icons displayed on the monitor. The application program can be activated by the user to provide functionality such as distribution of e-mails to the IDs of selected icons.Type: ApplicationFiled: January 29, 2002Publication date: November 21, 2002Inventors: Chien-Chung Li, Gen-Kuo Li, Chien-Fu Li, Yi-Te Lin, Chun-Ming Liao, Chien-Cheng Chang, Ling-Yen Lu, Ting-Wei Lu, I-Ping Fang
