Patent JP-H11218483-A (JP)
Title: Viscoelasticity measuring apparatus
Inventor: NAKAMURA NOBUTAKA
IPC: G01N19/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To measure static and dynamic viscoelasticities of a sample without receiving an influence from an elastic modulus of an elastic material which is supporting a detecting bar. SOLUTION: A part of a sample 1 is held by a detecting bar 6 elastically held by a support 12 variable at its opposed position to a sample holder 2 for holding an end of the sample 1. When a force of a DC or an AC is applied to the bar 6, a displacement of the bar 6 to the support 12 is detected. In this case, a position of the support 12 is altered or the force of the DC is changed so that the displacement is reset to zero.

Title: Copying machine
Inventor: IWAHASHI HARUO
IPC: G03B27/62
Filed: 1988-12-27
Abstract: PURPOSE:To form a complete stripping area without any shadow or density unevenness and to simplify a constitution by forming a void area which is created by combinating a reflecting surface and a white surface in the leading edge part of an original. CONSTITUTION:When an optical system 4 moves below the leading edge part 3(a) of an original 3, the white surface 131 is irradiated with light from a main reflecting mirror 7 and an auxiliary reflecting mirror 8, and reflected light to form the void area is taken out of a slit 9. A reflecting plane 121 in a void producing part 11 reflects incident light from a mirror 7 toward the original 3. The white plane 131 provided below the reflecting plane 121 forms the void area at the formed end of copying paper. The incident light from the mirror 7 is reflected by the reflecting mirror 132 toward the white plane 131 and irradiates its inside part. The protruding, leading edge of the white face 131 prevents the trailing edge of the reflecting plane 121 from being projected as a picture.

Title: Hydrofluoric acid vessel
Inventor: NOZAWA TATSUO
IPC: C04B35/565
Filed: 1988-12-27
Abstract: PURPOSE:To obtain a heat-resistant vessel which is not eroded by hydrofluoric acid, by making a vessel with Al-SiC material and providing the surface of the vessel with a porosity less than a specified value and further by providing a flange having a less surface roughness less than a specified figure at one end or both ends of the vessel. CONSTITUTION:A hydrofluoric acid vessel is made of Al-SiC material and the porocity of the vessel surface is less than 0.5% and also a flange having a surface roughness less than 0.5mum is provided at one end or the both ends of the vessel. The reason why the porocity on the vessel surface is restricted to be within 0.5% is that hydrofluoric acid solution percolates through the pores to damage it on heating when the porocity is more than 0.5%. The reason why the surface roughness of the flange surfaces 14a, 15a are restricted withind 0.5mum exists in protecting the heated hydrofluoric acid solution from leaking through the vessel by providing a groove for the O-ring on the companion flange to closely fit to the flange of the vessel and by fitting the O-ring on the flange.

Filed: 1992-12-09
Abstract: PURPOSE:To prevent lean misfire and avoid unburned HC discharging by prohibiting fuel injection when asynchronous injection is judged to be divided in judging whether or not asynchronous injection is divided by the opening of an-ark intake valve. CONSTITUTION:In asynchronous injection conducted by an, asynchronous injection means in starting or accelerating an internal combustion engine, injected fuel is possibly divided by closing an intake air valve 4. An injected fuel division judging means judges that injected fuel is divided from the crank angles at the time of starting asynchronous injection obtained by calculating the crank angle detected by a crank angle detecting means by an asynchronous injection crank angle calculating means 10 and a crank angle at the time of injection completion and a crank position at the time when closing the intake air valve 4 of each cylinder detected by an intake air valve opening timing detecting means. While injected fuel is not divided, fuel is injected by the asynchronous injection means as usual. While it is divided, fuel injection is prohibited by a first fuel injection controlling means. The synchronous fuel injection conducted synchronically with a crank angle is performed by a synchronous injection means.
