Title: Decorative sheet
Inventor: SADASUE SATOMI
IPC: B32B27/30
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a decorative sheet excellent in stain resistance and weatherability and having lasting antistatic effect. SOLUTION: A decorative sheet has layered constitution wherein a conductive layer 3 is interposed between a thermoplastic resin substrate layer 1 and a surface layer 2 comprising a thermoplastic fluoropolymer resin or the conductive layer 3 is interposed between the thermoplastic resin substrate layer 1 lined with a fibrous base material layer and the surface layer 2 comprising the thermoplastic fluoropolymer resin. Charge becomes hard to accumulate by the static electricity shielding effect developed by the conductive layer and the adhesion of dust can be suppressed. By providing the conductive layer between the substrate layer and the surface layer, the surface of the conductive layer is protected by a film and antistatic effect lasts for a long time.

Title: Store and batch demodulating device
Inventor: FUJI TAKESHI
IPC: H04L27/22
Filed: 1991-06-12
Abstract: PURPOSE:To enable accurate estimation and to apply the device to a system having no time slot as well by deciding an estimation executing period according to a detection signal generated based on the presence/absence of received signals. CONSTITUTION:A received signal detection circuit 11 detects a block, where the received signal is existent, from the output of a low-pass filter 2 and supplies the detection signal for regulating the executing period of bit timing estimation to a bit timing estimation circuit 3. When the detection signal shows the absence of received signals, the bit timing estimation circuit 3 stops a processing for estimation. The detection signal of the detection circuit 11 is transmitted to a delay circuit 12 as well, delayed only for time required for the estimation and inputted to a carrier frequency/phase estimation circuit 7 and when the detection signal similarly shows the absence of received signals, the estimation processing is stopped. Namely, data in the noise block, where no received signal exists in the input signal can be removed and accurate estimation is enabled.

Title: Magnetic resonance imaging apparatus
Inventor: YOSHIDA TADATOKI
IPC: G01R33/30
Filed: 1988-07-06
Abstract: PURPOSE:To taken an image even in a state other than a lying state without giving unnecessary mental fluctuation to a patient by mounting a tilting mechanism for arranging an examinee in the static magnetic field formed between superconductive blocks at an arbitrary angle with respect to a floor surface. CONSTITUTION:Superconductive blocks 1 are arranged to the respective end parts of a U-shape yoke heel piece 2 so as to be opposed to each other in parallel to form a static magnetic field B in the space between both blocks. The relative relation between the static magnetic field B and an examinee P can be variously set by the action of the revolving mechanism of a static magnetic field generating magnet device and that of the reclining and lift mechanisms of a stand apparatus for placing the examinee and the examinee P can be placed in various postures by the action of the lock mechanism of the stand apparatus for placing the examinee. By this method, the image of the arbitrary region of the examinee P taking a posture other than a lying position can be taken. Of course, the imaging of the same lying position as a conventional one can be also performed. Further, since imaging is performed between both ends of the opened U-shaped yoke heel piece, the unnecessary mental fluctuation given when the examinee P is inserted in a narrow space can be eliminated.

Title: Magnetic head supporting mechanism and magnetic disk device
Inventor: ITOU KIYONARI
IPC: G11B21/02
Filed: 1993-07-07
Abstract: PURPOSE:To provide a head supporting mechanism suitable for miniaturizing a magnetic disk device by providing a means making the change in a yaw angle zero even when a radial position of a magnetic head on a disk surface is changed. CONSTITUTION:By connecting a point on a load spring attaching part 8 with an optional point on a casing 10 and holding a distance between them to a fixed value, the orbit of the magnetic head describes a circular arc. Further, the load spring attaching part 8 is moved straight on a rigid body 6 connecting a circular arc structure 5 concentric with the center of the rotation of the magnetic disk 2 and with a radius larger than the magnetic disk 2 with the center of the rotation. Thus, the position of the load spring attaching part 8 is decided to an intersected point between the rigid body 6 and a circular arc orbit. Thus, when the circular arc structure 5 is rotated, and the rigid body 6 is moved, the position of the magnetic head is changed without occurring the yaw angle in a circumferential direction by a yaw angle canceling mechanism provided on the load spring attaching part 8.

Title: Optical recording medium
Inventor: HORIE KIYOSHI
IPC: G11B7/00
Filed: 1987-07-06
Abstract: PURPOSE:To enable the reading of the information indicating the top word of data from the optical recording medium itself by forming clock tracks which have the irregular clock bits disturbing regularity co-existing in regularly arranged clock bit rows. CONSTITUTION:The recording medium is constituted of the clock tracks 30 and the data track parts 40 consisting of plural data arrays 1-n juxtaposed therewith. The n bits of the data arrays 1-n read at one time in accordance with one clock bit are determined as one word. The one clock track 30 is as a rule the array of the clock bits 32 at equal intervals in one row and has the irregular clock bit 47 of the shape in which the clock bit corresponding to the top word 46 of the data is connected to the next clock bit for said top word 46. The spacing A between the irregular clock bits is determined at the number of the bits at which the locked state of a PLL circuit can be maintained or above. The information indicating the top word of the data is thus read without decreasing the recording density of the data by allowing the irregular clock bits disturbing the regularity to co-exist in the clock bits.
