Title: Light scattering film
Inventor: TANAKA KOICHI
IPC: G02B5/02
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To lessen whitening of a display image even at a high haze value and to obtain a display screen having excellent visibility, by making the ratio of forward scattering higher than the ratio of backward scattering. SOLUTION: The light scattering film consists of a light scattering layer consisting of a resin layer dispersing particulates in it and a transparent film. The refractive index of the particulates constituting the light scattering layer is made higher in refractive index than that of a resin layer exclusive of the particulate parts. The haze value of the film is set at >=20% in order to enhance light scatterability and further the forward scattering coefft. (F) obtd. by equation: F=Lb/Ld indicating the degree of the forward scattering and the backward scattering is preferably set at >=2.5. In the equation, Lb is the L* value of a chromaticity meter when the light scattering film is installed on a mirror finished surface reflector and indicates the degree of the forward scattering. The forward scattering is greater as the value is higher.  Ld is the L* value of the chromaticity meter when the light scattering film is installed on a light absorber and indicates the degree of the backward scattering the backward scattering is greater as the value is greater.

Title: Scum remover
Inventor: NISHIMOTO KAZUTAMI
IPC: A47J43/28
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To easily and surely remove the scum floated to the surface of soup in a short time without loosing the essence of soup. SOLUTION: By stirring soup S with an absorber part 3 so as to sink it under the surface layer of the soup, an absorbing means 6 absorbs scum P and the top clear part of the soup S in a short time, and the scum P is stuck into this absorbing means 6. Then, when the absorber part 3 is put up from the inside of the soup S, only the clear soup S from which the scum P is removed is discharged by its dead weight. Therefore, the scum P floated to the surface of the soup P can be easily and surely removed in a short time. Besides, since the absorbing means 6 can be easily washed by relatively moving pressing means 4 and 5 through an operating means, this absorbing means can be repeatedly used again and again.
