Patent JP-H0419803-A (JP)
Title: Magnetic recording/erasing device
Inventor: SAITO KAZU
IPC: G11B5/024
Filed: 1990-05-12
Abstract: PURPOSE:To prevent the miserasion of the information recorded on an erased track and also to prevent the inadvertent erasion of information by increasing the swing width of an erasion head with an unrecorded or unnecessary adjacent track and reducing the swing width of the erasion head with a recorded track respectively. CONSTITUTION:When the recorded information is erased with an erasion head which is usually set on the center of a recorded track, the swing width of the erasion head is varied according to a recorded or unrecorded adjacent track or the single-track or full-track erasion. That is, the swing width of the erasion head is reduced if an adjacent track is already recorded and then increased if the adjacent track is not recorded yet respectively. In other words, the track width to be erased is surely covered. Thus it is possible to prevent the inadvertent erasion of the necessary information recorded on an adjacent track and also to perfectly prevent the miserasion of the information on an erased track as long as the information recorded on the adjacent track is not necessary.

Title: Suspension arm support structure
Inventor: YANO AKIYOSHI
IPC: F16F15/08
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a suspension arm support structure that maintains predetermined strength of a shaft as well as ensures sufficient volume of a bushing both for sufficient damping performance. SOLUTION: A shaft 32 projecting from a lower arm is formed at its portion ranging from its base 32A to its axial substantially middle portion with an outside-diameter variable part 34 of outside diameters gradually and linearly reduced. A bushing 50 is formed at its inner cylinder 52 ranging from one end to the axial middle portion with an inside-diameter variable part 54 of inside diameters gradually reduced corresponding to the outside-diameter variable part 34. The reduced outside diameter of the inner cylinder 52 permits an increase in thickness of a rubber part 58 for increased elastic compliance, which effectively suppresses vibrations or thrust loads as compared with existing bushings.  The portion of the shaft 32 nearer to the lower arm is thus reinforced with the outside-diameter variable part 34 for constant total strength of the shaft 32, which prevents the shaft 32 from breaking up or cracking even upon receiving shearing force applied as part of vibrations, thrust loads or longitudinal force.

Title: Semiconduvctor laser element and manufacture thereof
Inventor: WATANABE NOZOMI
IPC: H01S5/00
Filed: 1986-05-29
Abstract: PURPOSE:To assure the high output by a method wherein an active layer is made of high compensation Si doped GaAs crystal; a GaAs crystal is formed on the part corresponding to an oscillating region above a clad layer; a metallic electrode and a GaAs layer of current injection part are brought into ohmic contact; and other parts are simultaneously Schottky junctioned. CONSTITUTION:Most of the light emitted in an active layer 3 is closed in the active layer 3, however, a bit of evanescent fields are to be left on clad layers 2, 4. On the other hand, the field distribution in the regions not containing a GaAs layer 13 is differentiated due to the existance of a metallic electrode while the region containing the GaAs layer 13 and the other regions not containing the same are subjected to the equivalent difference in refractive index to close the emitted light in the horizontal direction. The light in the vertical direction is closed by the first clad layer 2 and the third clad layer 12 to be transmitted between the active layer 3 and the GaAs layer 13. Especially, the light emitted from the Si doped GaAs active layer 3 having longer wavelength than that at the absorbing end of GaAs is not absorbed into the GaAs layer 13. Resultantly, the sectional area of photowaveguide is three layered forming so-called LOC (large optical cavity) to assure the high output characteristics.

Title: Radial ball bearing for protection in magnetic bearing device
Inventor: KAWAKAMI YOSHIHISA
IPC: F16C32/04
Filed: 1987-05-20
Abstract: PURPOSE:To reduce centrifugal force acting on balls and improve durability of a bearing in the case of touch down by making the diameter of the pitch circle of a radial ball bearing for protection smaller than its normal average diameter. CONSTITUTION:In case of high speed touch down, as thickness te of an outer ring 13 is large, expansion of the outer ring 13 itself generated by a centrifugal force at rotation is small, and as a change of clearance inside of the bearing is small, its rotation is smooth. Deformation of the outer ring 13 generated in the case of making contact with a rotor becomes smaller, because thickness te of the outer ring 13 is large, and its rotation becomes smoother, because unreasonable force does not act on balls 11. Rigidity of the outer ring 13 becomes higher, because number of balls is increased by making the diameter Da of each ball 11 smaller. As the diameter dp of a pitch circle is small, orbital speed of the ball 11 becomes smaller and centrifugal force acting on the ball 11 also becomes smaller at rotation. Therefore, durability of the bearing 10 is improved.

Title: Coordinate input device
Inventor: YOSHIMURA YUICHIRO
IPC: G01B17/00
Filed: 1986-05-30
Abstract: PURPOSE:To enable a coordinate to be calculated with resolution higher than ever, by correcting a time corresponding to a difference between the maximum position of an envelope in a pulse group, and the peak position of the maximum peak level in the pulse group, to a time value until the maximum peak level in the pulse group that is a detection signal is detected. CONSTITUTION:Assuming a corrected time as 'T', and a time correction value corresponding to a pulse width 'Z' as P(Z), in case of setting the time required until the pulse with the maximum level in the pulse group is detected at 't', T is expressed as T=t+P(Z). Also, the P(Z) has the maximum width of Z0 assuming the pulse width when a pulse 50 is set as a threshold value, as Z0, therefore, it is expressed as 0<Z<Z0. Consequently, P(Z) is expressed as P(Z)=-1/fXZ/Z0, and in this case, 1/f shows one cycle of a phase velocity. Consequently, 0<=Z/Z0<1 is resulted, and it is possible to correct to the time value within one wavelength of the phase velocity.
