Title: Bed
Inventor: KIMURA GAKUJI
IPC: A47C20/10
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a bed which is a low floor type which can secure sufficiently a large space under a floor board. SOLUTION: An arm pipe 81 is energized in the circumferential direction by a torsion bar 88 installed along the arm pipe 81 so that a roller 83 side part of an arm 82 may be moved to the floor board section 60 side. The roller 83 of the arm 82 is abutted against the floor board section 60 by the energization force by the torsion bar 88 and then pushes up the floor board section 60. Driving force for raising and lowering the floor board section 60 can be compensated by the torsion bar 88 installed in the width direction, not in the longitudinal direction, of a bed frame section 50. Compared with a case that an energization means is installed in the longitudinal direction of the bed frame section 50, the existence of the torsion bar 88 never prevent the securing of a space under the floor board section 60.  Due to this structure, a sufficient space can be secured under the floor board section 60 in this low floor type bed.

Title: Block distortion improving system
Inventor: HASEGAWA MAKOTO
IPC: H04N1/41
Filed: 1989-11-28
Abstract: PURPOSE:To minimize th. deterioration in the picture quality caused following the block distortion improvement processing by estimating the part of occurrence of block distortion at a receiver side in a 2-dimension DCT transformation coding system, applying picture processing to the part and improving the block distortion. CONSTITUTION:A sender side of the DCT transformation coding system takes a difference between picture information and predicted picture for each prescribed block with respect to the picture information. Then a DCT transformation coefficient series obtained by applying the 2-dimension discrete cosine transformation(DCT) is coded and the result is sent to a receiver side. The receiver side estimates whether or not block distortion is generated in the block from the DCT transformation coefficient for each sent block and when the block distortion generation is estimated, the picture processing to improve the block distortion is implemented as to the block. In this case, the picture processing applies, e.g. low pass filter to eliminate high frequency component. Thus, the block distortion generating part as to the receiver side is estimated and the picture processing is applied to the part to improve the block distortion, then the block distortion improving processing by the receiver side processing only is attained.

Filed: 1989-11-29
Abstract: PURPOSE:To reduce the size of a device by forming a core layer which has a rib part with a curved part on a substrate and making the curved part of the rib thicker radially inside than outside. CONSTITUTION:On the SiO2 glass substrate 1, the core layer 2 which has the rib part 3 projecting upward is formed by using UV setting resin which has a larger refractive index than the substrate 1.
