Title: Production of magnetic recording medium
Inventor: IWASE TAKAYUKI
IPC: G11B5/84
Filed: 1989-04-21
Abstract: PURPOSE:To lessen drop-outs, AM modulation noise and skew by executing the application of a magnetic layer, calender treatment, the application of a back layer, and the bulk thermo-treatment after grinding of the back layer through the series of processing. CONSTITUTION:A base 1 is coated with a coating liquid 4 for the magnetic layer in a ferromagnetic powder applying section 3 and is thereby formed with the magnetic layer. After the magnetic layer is subjected to a magnetic field orientation treatment, the layer is dried in a drying section 8. The base 9a formed in such a manner enters a calender section 10. The base 9a is calendered in the calender section 10 and a web provided with the magnetic layer having a smooth surface is formed. The back layer is applied on the opposite surface of the magnetic layer in a back applying section 11. The base is sent to a drying section 16 and thereafter, the back surface is ground in a grinding section 17, by which the tips of projections are cut. The double-coated web 8b is taken up in a take-up section 21 after dust removal and the roll 21a thereof is carried to a thermo-chamber 22 where the strains of the tape are relieved by the bulk thermo-treatment. The increase in the AM modulation noises and the drop-outs is prevented in this way.

Title: Method for preventing distortion of metal sheet
Inventor: KANEKO NORIYUKI
IPC: B23K26/38
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent the distortion of a sheet by forming a cut or a groove at required parts of the sheet for die parts. SOLUTION: A metal sheet 1 is successively pressed by a die to successively form a corrugated bent part 2a. A cut 2b is made between bent parts 2a, 2a adjacent to each other of an intermediate stock 2. The cut 2b can eliminate the tensile or compressive internal stress in the surface, and prevents generation of the distortion caused by the effect of the size and bending. A blade whose bent parts 2a is cut off by the laser beam is added to the surface of a tire vulcanizing-forming die to form a large number of cuts in a tire tread. A metal sheet may be formed in a groove shape, and the quantity of the distortion is preferably adjusted by changing the shape, the number and the position of the cuts 2b according to the cause of the distortion of the metal sheet. The safety and the workability by the laser beam machining in the post-process can be improved thereby.

Title: Wheel speed detector and wheel slip controller
Inventor: YAMASHITA TETSUHIRO
IPC: B60T8/171
Filed: 1994-05-16
Abstract: PURPOSE:To determine noise surely by making such a decision that noise is generated due to fluctuation in the external field when a wheel sensor starts to output a pulse signal and the period from the start of the output until a predetermined number of times of the output corresponds to a frequency within a predetermined range. CONSTITUTION:The speed detector for detecting the wheel speed of respective wheels comprises wheel speed sensors 26-29 each converting the variation of flux into the variation of voltage. The sensors 26-29 are affected by magnetic field variation if a significant variation of external magnetic field occur and noise appears in the output signal. When the sensor 26-29 starts to output a pulse signal in normal noiseless state, the number pf pulses increases gradually at first with a short period. A decision is then made whether the period of pulse signal corresponds to an abnormal high frequency before the pulse signals are outputted by a predetermined number of times thus deciding whether an output signal represents a noise caused by the fluctuation in the external magnetic field.
