Filed: 1991-08-21
Abstract: PURPOSE:To suppress noise and a vibration with a sine wave magnetic flux distribution maximum at the center of a pole by regulating a distance between each tooth and the magnetic flux surface of a rotor when one pole is formed of a group of a plurality of teeth to be magnetically continued through winding. CONSTITUTION:A plurality of teeth 5 are extended in a comb-like state to the bore side of a doughnut-like yoke 4 to form sixteen slots 6.

Title: Double head supporting mechanism for magnetic disk drive
Inventor: YASUDA MASARU
IPC: G11B17/32
Filed: 1985-09-21
Abstract: PURPOSE:To suppress an off-track quantity to the minimum, by constituting an arm body in such a way that its tail end side can be supported by a common supporting spring under a freely swingable condition against a carriage and the upper and lower heads carried by the arm body can follow the upward and downward movement produced during the rotation of a magnetic disk. CONSTITUTION:An arm body 24 swings in the upward direction by means of the bend of a common supporting spring 54 while holding an upper and lower heads 20 and 22 integrally as they are. Therefore, the arm body 24 can completely follow the upward and downward movement of a disk 100 and does not give any excessive stress to the disk 100. Moreover, it is not necessary to make the loading pressure unnecessarily large and the optimum loading pressure can be given to each of the upper and lower heads 20 and 22 under following conditions. In addition, since the swinging motion of the arm body 24 is made by using the sufficiently long distance (l) from the fulcrum of a carriage 16 to the center of the heads as an arc, the heads 20 and 22 can follow the vertical movement of the disk 100 without causing any displacement in X direction, namely, without causing any off-track.

Title: Low pressure spike tire
Inventor: KOBAYASHI HIROSHI
IPC: B60C11/16
Filed: 1985-09-20
Abstract: PURPOSE:To prevent slip from occurring and to prevent the road surface from being damaged by arranging pins in a tire tread so that the pins can be either extruded or retracted from the tread surface by pressing the bottom of the pins toward the outside by means of a resilient member having required resilient force and that the pins penetrate only into ice- or snow-covered road surface. CONSTITUTION:Below the tread surface 2 of a tire 1 is arranged a retainer 3 in which a pin 4 and a spring 5 are installed. The cross-sectional area of the bottom 4C of the pin 4 is made greater than that of the stem portion 4B of the pin 4 to prevent the pin 4 from coming off. The spring 5 is made to have such a pressing force that enables the pin to penetrate into ice, snow and the like. This makes the tip portion 4A penetrate into ice or snow only when the tire 1 is driven on ice- or snow-covered road surface by pushing back the pin 4 means of the spring 5. Accordingly, anti-slip effect of the tire 1 on the ice- or snow-covered road surface can be improved. On the other hand, on the ordinary road surface, since the resistance of the road surface pushes back the spring 5, the tip surface 4A of the pin 4 does not penetrate into the road surface.

Title: Method and apparatus for measuring amount of plated material of plated steel plate and composition of plated film
Inventor: NISHIFUJI KATSUYUKI
IPC: G01N23/223
Filed: 1989-08-17
Abstract: PURPOSE:To make it possible to measure the amount of plating and the composition of plating highly accurately by correcting the shifted amount of a wavelength due to Compton scattering obtained by the incident angle and the received angle of monochromatic X rays. CONSTITUTION:At first, monochromatic X rays are projected on a scattering plate by using the same optical system as in the measurement of a plated steel plate. The wavelength of the monochromatic X rays is measured from a theoretical expression by using the wavelength of Compton scattering lines. An optical system is adjusted so as to obtain an intended wavelength. Then, the theoretical computing expression for fluoresence X-ray intensity or the intensity ratio of the element for intended analysis obtained by using said optical system is determined beforehand. Then, a standard sample is used, and a converting coefficient for converting the actually measured values into the theoretically computed value is obtained beforehand. The fluorescence X-ray intensity or the intensity ratio obtained from the plated steel plate whose plated amount and composition of the plated film are unknown is measured. The values are converted into the theoretical intensity or the intensity ratio by using the converting coefficient. The plated amount and the composition of the plated film of the plated steel plate to be measured are determined from the plated amount and the composition of the film which are the parameters in the theoretical computing expression that are most close to the converted theoretical intensity or intensity ratio.
