Publication number: 20180276766Abstract: An automatic journalizing device includes a collation unit that collates the content of journalizing target detail data which is input by a detail data input unit with the content of already journalized detail data stored in a detail data storage unit, so as to determine whether or not a determination item matches each other, and an automatic journalizing unit that sets the same account title as an account title set for the already journalized detail data, for the journalizing target detail data, in a case where it is determined that matching occurs. By using already journalized detail data for which an account title is already set without using a correspondence table related to a keyword, it is possible to prevent the occurrence of a problem that accurate automatic journalizing cannot be performed since there is no keyword of the correspondence table or a plurality of keywords are included.Type: ApplicationFiled: March 13, 2018Publication date: September 27, 2018Inventors: Katsuteru Murakami, Osamu Nagahama, Yasushi Nakai, Rintaro Sonoda, Hiroyuki Omura, Shinji Tokuyama

Cylinder liner and cylinder block and method for producing the cylinder liner and the cylinder block
Patent number: 5727511Abstract: A cylinder liner or a cylinder block's bore portion formed of a composite alloy material reinforced with fibers and dispersed with ceramic particles. In the cylinder liner or the bore portion of the cylinder block, ceramic particles and alumina short fibers are uniformly dispersed in a light metal matrix. For producing the cylinder liner and the cylinder block, a preform having a shape identical with the cylinder liner or the bore portion is produced by mixing together the ceramic particles and the alumina short fibers. Molten light metal is infiltrated into voids of the preform during casting.Type: GrantFiled: April 23, 1996Date of Patent: March 17, 1998Assignees: Ryobi Ltd., Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Hiroyuki Omura, Shin Nitta, Yosuke Takahashi, Hirotake Usui, Jun Isomoto, Haruhisa Mori, Takashi Yamaguchi, Hiroshi Miyazaki
