Patent number: 6122979Abstract: When there is a difference in characteristic between sensing devices received respectively in receiving portions disposed at the opposite ends of a shackle pin and, therefore, the voltage of a load signal obtained from the sensing device in the receiving portion side is higher than the voltage of a load signal obtained from the sensing device in the receiving portion side because of the above-mentioned difference even if the loads imposed on the receiving portions respectively are equal to each other, configuration is made so that a correction resistor is parallelly connected to a detection winding of the sensing device in the receiving portion side. Accordingly, a part of the induced current flowing between opposite ends of the detection winding also flow in the correction resistor, so that a voltage drop occurs in the correction resistor.Type: GrantFiled: May 5, 1998Date of Patent: September 26, 2000Assignee: Yazaki CorporationInventors: Masaya Tsuchie, Naoya Takahashi

Patent number: 5606529Abstract: A semiconductor storage device transfers data with an information processing device and includes a non-volatile semiconductor memory in which data is electrically re-writable, a volatile semiconductor memory connected to the non-volatile memory and temporarily storing data of the non-volatile semiconductor memory, and a CPU connected to the volatile semiconductor memory and the non-volatile semiconductor memory. The CPU controls the transfer of data among the non-volatile memory, the volatile memory and the CPU. The CPU also transfers data with the information processing device in accordance with a fixed-length form for data. When an access from the CPU to the volatile semiconductor makes a miss hit (i.e., misses), the CPU accesses the non-volatile semiconductor memory. When a failure is generated in the non-volatile semiconductor memory or when a predicted service life of the non-volatile semiconductor memory is elapsed, the non-volatile semiconductor memory can be substituted by an alternate memory.Type: GrantFiled: March 6, 1996Date of Patent: February 25, 1997Assignee: Hitachi, Ltd.Inventors: Hisao Honma, Kazuo Nakagoshi, Naoya Takahashi, Makoto Kogai, Kenichi Takamoto

Patent number: 5606706Abstract: The write data is entered from the upper unit into a nonvolatile cache provided in a controller inside of each disk unit through a channel adaptor, a cache shared by each disk, and a disk adaptor. The data from the cache is compressed by the data compressing and restoring device and is written in the disk. At a time, the management information for compressed data is written in the cache and the disk as well. In case of breaking the management information of the cache when a failure takes place in the cache memory, the management information is written for each disk. Hence, the breakage does not have an adverse effect on the other disks. If the management information of the cache is broken, the management information given into the disk may be replaced with the broken information.Type: GrantFiled: August 22, 1994Date of Patent: February 25, 1997Assignee: Hitachi, Ltd.Inventors: Ken-ichi Takamoto, Kazuo Nakagoshi, Naoya Takahashi, Makoto Kogai, Minoru Yoshida
