Patent number: 6238626Abstract: In a method for distributing liquids, in which a distribution tip attached detachably to the lower end of a distribution nozzle can be replaced at any time necessary, a tip rack having a plurality of unused distribution tips lined up thereon is placed on a fitting stage to have the distribution tips fitted with a distribution nozzles. Then, the existence, or non-existence, of a distribution tip left behind on the tip rack without being attached to a distribution nozzle after the fitting operation is finished is detected by a detection section formed of an interrupting-type light sensor, the targeted place of detection by the light sensor being the lower end of the distribution tip. Under the above-described structure, misfitting of a distribution tip can be detected with a high certainty at an early stage before an operation for sucking/discharging liquids is started.Type: GrantFiled: April 12, 1999Date of Patent: May 29, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akira Higuchi, Eiji Watanabe, Naoki Miyazaki, Kanji Yahiro, Kenichi Kuroda, Hideyoshi Kitahara, Kenji Ishiyama, Takashi Daikoku

Patent number: 3950165Abstract: A method of sintering ferrous materials comprises mixing an iron powder with an alloy of iron-titanium and forming a liquid phase during the sintering. The alloy is prepared by mixing selected amounts of iron and titanium powders to form an iron-titanium alloy powder consisting essentially of 14 to 46% by weight of titanium and the balance iron, and preferably 14 to 30% by weight of titanium. The sintering step is carried out at a temperature at which the powdered mixture is always in the liquid phase during sintering. Under these conditions oxidation of titanium is suppressed during melting and the alloy is not too soft nor too difficult to pulverize and used for manufacturing the machine components such as piston rings which have surprisingly good properties due to the use of the critical amounts of iron and titanium in the alloys useful according to the invention.Type: GrantFiled: September 6, 1973Date of Patent: April 13, 1976Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Teishiro Oda, Takashi Daikoku
