Title: Method for casting polyamide sheet
Inventor: TSUNASHIMA KENJI
IPC: B29C41/26
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To perform rapid casting or uniform orienting or the like of a sheet by casting so that a holding angle between a tangential line drawn on a moving cooling medium at a contact point of a sheet with the medium and a tangential line drawn to a corresponding circle of an orbit of the sheet becomes specific. SOLUTION: A polyamide raw material obtained by mixing a liquid crystal polymer or the like with a polyesteramide or the like is dried, dehydrated, then melt extruded in a nitrogen flow or in vacuum by a melt extruder without lowering a molecular weight, ionomers are laminated on both surfaces of a polyamide resin layer, and the obtained laminated melt sheet 7 is cooled and solidified by a moving cooling medium 2. Thus, a holding angle 6 between a tangential line 4 drawn at a contact point P of a melt sheet 7 extruded from a mouth 1 and the medium 2 and a tangential line 5 drawn at a point P of an imaginary corresponding circle 3 including as many locusses of the melts as possible exceeds 0 degree. Before the sheet 7 is brought into contact with the medium 2, a water membrane or static charge is formed on the medium 2, the sheet 7 is brought into contact with a drum and quenched.  Thus, rapid casting can be achieved, and excellent homogeneity of a thickness of and stretchability of the film can be obtained.

Inventor: TSUZUKI YOSHINORI
IPC: G01M99/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality detecting method in which the abnormality of the high-pressure rotation system and the low-pressure rotation system of a two-spindle gas turbine engine can be detected surely without using a complicated apparatus. SOLUTION: The relationship β=f(α) between the rotational speed α of the low-pressure rotation system of a two-spindle gas turbine engine and the rotational speed β of its high-pressure rotation system is set in advance. When a measured rotational speed of the low-pressure rotation system or the high- pressure deviates largely from the relationship, the rotation system is detected to be abnormal. In addition, a prescribed threshold value Δα and a prescribed threshold value Δβ are set with reference to the relationship, and the rotation system which exceeds the threshold values is detected to be abnormal.

IPC: F02F3/00
Filed: 1995-03-13
Abstract: PURPOSE: To improve detection precision of knocking by a method wherein, during knocking, the resonance frequency of a constituting part is regulated so that detectable vibration detectable by a knock sensor is encouraged. CONSTITUTION: When a piston 16 used in an internal combustion engine having a knock sensor is cast and moulded, a machining margin 16g attributed to rigidity of a skirt part 16e is arranged on the back of an upper surface part 16f.

Title: Secondary air supply unit for engine
Inventor: NAKACHI MASAAKI
IPC: F02M35/024
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To simplify the structure, reduce the man-hours required for assembly/ disassembly and minimize costs by forming inside an air cleaner a reed valve compartment for accommodating a reed valve that opens/closes the secondary air duct, and integrally molding the connection pipe to be connected to the secondary air pipe and the air cleaner body. SOLUTION: During engine operation, foreign matter in the air is filtered by a filter 3 of an air cleaner 2. The filtered air is then mixed with fuel in a carburetor 4. Secondary air, which is part of the air that has passed through the air cleaner 2, activates a reed valve 102 to open. More precisely, when the pressure in an outlet compartment 2a becomes higher than that in a reed valve compartment 103 due to the differential pressure between the inlet/outlet of the reed valve 102, which is caused by the exhaust pulsation in an exhaust pipe 7, the reed valve 102 opens. Accordingly, the secondary air is supplied to the exhaust pipe 7 via a secondary air pipe 9. At this time, part of an air cleaner body 101 is projected out and the casing 104 and connecting pipe 105 are integrally molded such that an entire reed valve unit 110 is integrated with the air cleaner.

Title: Initialization of photosensitive body
Inventor: KURATO SHIGEO
IPC: G03G21/14
Filed: 1986-03-11
Abstract: PURPOSE:To prevent a cleaning blade from damaging a photosensitive body by reducing the luminous energy of an original lighting lamp less than that at the time of normal transfer, carrying toner on the photosensitive body by simulation and bringing the cleaning blade into contact with the photosensitive body at the prescribed timing. CONSTITUTION:A control part 43 drops the impression voltage of the original lighting lamp 4a to 55V, for instance, from a normal 65 V, and drives said lamp with less luminous energy than that at normal transfer. This occurs because the toner will not carry on the photosensitvie drum 9 if the original lighting lamp 4a irradiates a white part 2a with the luminous energy at the time of normal transfer. When the original lighting lamp 4a irradiates the white part 2a with the less luminous energy, it produces the same effect as irradiating a grey original, thereby carrying the toner on the photosensitive drum 9. Namely the toner forming a positive image carries on the photosenstive drum 9, which rotates. Thanks to simulation for initialization, the toner being a lubricant between the photosensitive body and the cleaning blade easily and efficiently adheres to the photosensitive body.
