Title: Lubricating oil feeding device for engine
Inventor: YAMANAKA YASUTOSHI
IPC: F01M5/00
Filed: 1994-05-06
Abstract: PURPOSE:To effectively utilize lubrication oil in a heat insulation tank by reducing incurring of the friction loss of an oil pump. CONSTITUTION:An oil pump 4, an oil cooler 5, a heat insulation tank 6, and an oil filter 7 are arranged, in the order, in a lubricating oil passage 3 through which lubricating oil is guided to the slide part of an engine 2. A pressure regulating valve 9 to keep a system pressure approximately at a constant value is arranged in a communication passage 8 to bypass the oil pump 4 and intercommunicate a heat insulation tank 6 and a lubricating oil passage 3. In a lubricating oil feeding device 1, since, when during the low temperature starting of the engine 2, the number of revolutions of the engine is high, the system pressure of the lubricating oil passage 3 is increased to a value higher than the set pressure of a pressure regulating valve 9, most of lubricating oil the heat of which is insulated in the heat insulation tank 6 is returned through the communication passage 8 to an upper stream lubricating oil passage 3 with the aid of the oil pump 4 and an amount of lubricating oil flowing from the heat insulation tank 6 to the engine 2 side is decreased to a very low value.

Title: Apparatus for production of optical disk
Inventor: ONAKI NOBUAKI
IPC: G11B7/26
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to relieve a substrate temperature elevation and to form disks having good mechanical characteristics by forming thin films in a vacuum on optical disk substrates and disposing means for halting thin film formation at the time of formation. SOLUTION: A main chamber 13 internally has a cooling gas introducing pipe 17 having a valve 18 toward the optical disk substrate 19 arranged in a sputtering chamber by a substrate transporting mechanism in the position facing a target material 16 in a cathode 15 having a magnet. Cooling gaseous argon is passed toward the substrate from the cooling gas introducing pipe 17 to cool the substrate during the halt time of sputtering. The flow rate of the gas is changed by the halt time and the capacity of a vacuum pump and an effect is higher as the gas is passed at the largest possible flow rate. Krypton and gaseous xenon heavier than the argon is more effective than the argon for the cooling gas. Further, the effect is higher if the cooling gas is used by cooling the same down to room temperature or below, more preferably <=100 deg.C below zero.

Title: Artificial blood vessel and its manufacture
Inventor: MOROHOSHI YASUNORI
IPC: A61F2/06
Filed: 1989-04-14
Abstract: PURPOSE:To make a domestic endothelium compactly cover the blood vessel of a certain body as an implantation object over the blood contact side of an artificial blood vessel base material by preliminarily covering the implantation surface of the artificial blood vessel base material with collagen, and incubating the endothelium of the vessel. CONSTITUTION:It is possible to adopt any of conventional base materials including a woven polyester fiber for subject purpose. In order to incubate the transplanted endothelium of the blood vessel to such an extent enough to compactly cover the base material, a culture medium made of the non-serum culture of a linear fibrous cell added with a fetal calf serum and a growth factor is preferably used. As the concn. of the fetal calf serum increases, the growth is stimulated and a further high concn. of the fetal calf serum is required. Also, it is imperative to cover an implantation surface with collagen, prior to implanting a vessel endothelium to an artificial vessel base material. According to the aforesaid construction, the endothelium is deposited and incubated on the inner surface of the artificial vessel, and a compact covering condition is thereby ensured. As a result, the anti-thrombus function of the endothelium is sufficiently obtained.
