Title: Molten steel flow passage pipe for continuous casting
Inventor: NAKAJIMA MASUMI
IPC: B22D11/10
Filed: 1987-04-28
Abstract: PURPOSE:To prevent clogging of a nozzle and to reduce production cost by forming a pipe at position easily developing the clogging of flow passage by ceramic single substance of BN as main component or the inner and outer faces of the pipe by double construction of the ceramics. CONSTITUTION:The flow passage is formed by dividing into plural number of pipes and the pipes are joined to produce one piece of the flow passage. The position of the pipe easily developing the clogging of flow passage is formed by the BN pipe made of BN as the main component. Or, the double constructed pipe is formed by inserting the ceramic pipe 3 made of BN as the main component in the inner face and backing up the outer side by the other ceramic pipe. As BN component naturally has difficult property to wetting with the molten steel, the clogging of the nozzle caused by sticking of the molten steel or oxide is prevented by this construction. As the expensive BN ceramic is locally used only at the necessary position, the production cost is reduced.

Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire for high motion passenger car which excels in the water discharge performance when it runs at a cornering on a wet road surface. SOLUTION: This pneumatic tire has 10 to 50% of a tread width and is provided with many central inclined grooves 1 which are arranged in a central region of a tread and are extended in the direction in which they are inclined for the peripheral direction of the tire and many side inclined grooves 22 which are extended in the direction in which they are inclined for the peripheral direction of the tire and are opened in the central inclined grooves and tread ends. In this case, the side inclined grooves are mutually extended in the reverse directions across the central region of the tread to form a directional inclined groove in which a side close to an equatorial face of the tire in a part in which the groove is extended comes in contact with the ground first.  The central inclined grooves are extended in the direction in which they are inclined at an angle of 5 to 15 degrees for the peripheral direction of the tire and are extended by tilting in one direction in the central region of the tread so that a side close to an inner side of a vehicle comes in contact with the ground later when the tire rotates.

Filed: 1987-05-01
Abstract: PURPOSE:To judge the correctness of recording, by providing a means to detect the change of the reflected light of a recording beam of light by the recording of information, and a means to compare a detected signal with an information signal. CONSTITUTION:When the information is recorded by the projection of a laser beam, a reflected laser beam at the time of recording a space part becomes a 0-th order diffracted light 300 and a first-order diffracted light 301. Meanwhile, the reflected light at the time of recording a mark part becomes a 0-th order diffracted light 304 and a first-order diffracted light 305. When those diffracted light are compared, it can be observed that no different point in directions of the 0-th order diffracted light 300 and 304 exists, however, as for the first- order diffracted light, the diffracted light of the mark part has broadening larger than that of the diffracted light of the space part. Therefore, by providing the means to detect the change of the first-order diffracted light at the time of recording and the means to compare the detected signal with the information signal, it is possible to judge the correctness of the recording.

Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To achieve an excellent recording and/or reproducing characteristic from a state of a disk excellent in the strength, stable in the form, and in a highly smoothed state by using liquid crystal polymer as a material forming a base plate, molding it into almost a disk-like form, and by the fact that a molecular axis direction of an extended molecular chain is almost the same as the radius direction of a base plate. SOLUTION: To mold liquid crystal polymer by injection into almost a disk- like form with a hole formed at the center part, a molecular axis direction of an extended molecular chain is almost the same as the radius direction of a base plate 3. Moreover, a rugged pattern is deposited on the base plate 3, and substrates 4, magnetic layers 5, protective layers 6, and lubricating layers 7 are deposited on both main surfaces 3a, 3b in this order by a thin film deposition method, therefore, the magnetic layers 5 are also deposited in a rugged pattern. This magnetic disk has obtained such properties as a very small post- deposition contraction coefficient, an excellent dimension stability, a high Young' s modulus, and a good rigidity. These prevent the disk from thermal deformation and secure recording and/or reproducing.

Title: Paper carriage device
Inventor: MITEKURA AYAHIRO
IPC: G03G15/00
Filed: 1986-05-12
Abstract: PURPOSE:To enable the easy removal of jammed paper under a transfer belt by providing a means for moving the belt for recording paper in a direction opposite to a copying process when the paper has jammed in a copying machine proper. CONSTITUTION:When recording paper has stagnated in a copying machine and jammed before discharge through a fixing port 16, a transfer belt unit 1 turns down a transfer belt unit release lever 17, thereby lowering an idle roller 4 and releasing contact between sensitive material drums 5-8 and a transfer belt 2. Consequently, the recording paper jamming above the transfer belt unit 1 can be easily removed. When the recording paper has been carried under the unit 1, adsorbed on the transfer belt 2 without enough removal of electrical charge, however, a transfer belt reversal switch on a jam treatment panel is turned 'ON' and the running of a transfer belt drive motor is reversed, thereby carrying and stopping the recording paper on the unit 1 for the easy removal thereof.

Title: Production of optical recording medium
Inventor: YASHIRO TORU
IPC: G11B7/26
Filed: 1991-04-11
Abstract: PURPOSE:To allow coating with the accurate position control at the inner peripheral end of a light absorption layer and to execute stable reading out of information by executing the spin coating in the environment where the gaseous pressure on the central side of a substrate is higher than the atm. pressure on the outer peripheral side of the substrate. CONSTITUTION:This optical recording medium has the light absorption layer formed by spin coating on the substrate. The environment where the gaseous pressure on the central side of the substrate is higher than on the outer peripheral end side of the substrate is formed by circumferentially discharging gaseous nitrogen of a specified flow rate from a gaseous nitrogen outflow port 5 in this system. The flowing or splashing of a coating liquid by a difference in the atm. pressure does not arise on the inner peripheral side of the substrate and, therefore, the control accuracy in the position at the inner peripheral end is improved and the degradation in the recording capacity is obviated. The stable reading out of the information is thus executed.
