Title: Armature coil conductor and its manufacture
Inventor: MORIMOTO YOSHIHIRO
IPC: H02K15/04
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To permit application of a horn provided with protrusions having strength and endurance, as it is, without narrowing the interval between outer peripheral parts of lead parts of adjacent armature coil conductors, by making the armature peripheral direction dimension of the section of an oval lead part smaller than the armature peripheral direction dimension of the section of a rectilinear part. SOLUTION: On account of plastic deformation due to ironing work, the armature peripheral direction dimension 16c of the section of an oval lead part 16a of an armature coil conductor is smaller than the armature peripheral direction dimension 6e of a rectilinear part 6b of the armature coil conductor. The armature radial direction dimension 16d of the section of the oval lead part 16a is larger than the armature radial direction dimension of a round section of the rectilinear part 6b of the armature coil conductor. Thereby an interval 9 between the lead parts is not narrowed when the number of slots is increased or when the diameter of the armature coil conductor is increased. As a result, it is unnecessary to make a protrusion 7c thin, so that a horn can be applied, as it is.

Title: Focus error detecting system for optical disk device
Inventor: OZAWA YASUYUKI
IPC: G02B7/28
Filed: 1986-04-24
Abstract: PURPOSE:To obtain a stable focus error signal without an off-setting change by holding the error at the time of reading and separating the band with a conventional error output and executing the synthesizing. CONSTITUTION:By weighting and synthesizing a focus error signal S2 used conventionally and a sample value S1 at a frequency band by an amplifying means 18 with a bank limit, a focus error signal S3 to satisfy both two problems of making a gain constant and removing the influence of an off-setting can be obtained. The focus error signal S3 obtained in such a way is composed of a sample value S1 at the area where the influences of the change of the off-setting are many and the conventional focus error signal S2 at the high area where the influences due to the change of the off-setting are few. Thus, the influence of the off-setting to a focus control is significantly decreased and a sufficient control band can be obtained.

Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of a cell transmitting window and perform a highly precise analysis by setting the distance between the lower end of an inlet of inert gas and the upper end of an outlet thereof to a specified distance. SOLUTION: An introduced inert gas flows horizontally or upward in the upper part of a cylinder 1, but it is rectified only to a downward flow while carried in a distance L1 to form a rectified area L0 . When it passes the rectified area with the length L0 , a horizontal component is added to the direction of the flow because of the flow directing an outlet 3. When this distance is L2 , the distance L from the lower end of an inlet 2 to the upper end of the outlet 3 is the sum of L1 and L0 and L2 . The cylinder 1 is formed so that L0 is 10 mm or more. As a result of actual experiments, when the length of the rectified area L0 is 10 mm or more, an evaporated sample can be prevented from reaching a transmitting window 4.
