Patent JP-H0694050-A (JP)
Title: Electromagnetic clutch
Inventor: TABUCHI YASUO
IPC: F16D27/112
Filed: 1992-09-16
Abstract: PURPOSE:To provide an electromagnetic clutch excellent in assembleability between a rolling bearing supporting a rotor and a boss part, and capable of preventing any drag between the rolling bearing and the boss part from occurring at low cost. CONSTITUTION:A boss part 16 and an inner ring 18 in a rolling bearing 15 are installed in a gently fittable manner. In addition, a groove 20 is installed in and around the boss part 16, while an O-ring 21 is set up in an inner part of this groove 20. This O-ring 21 increases in its volume after the inner ring 18 is assembled to the boss part 16, and this ring 18 is locked to the boss part 16 owing to pressurization by an increase in the volume. Since it is small in its volume before being assembled like this, any possible worsening of assembleability is not incurred and, after assembling, its volume increases, clamping the inner ring 18 to the boss part 18 tight enough, and thus any drag of the inner ring 18 is kept back. Likewise, since no working is applied to the inner ring 18, any possible increase in cost is checkable.

Title: Chip discharging device in machine tool
Inventor: MIURA TOMIO
IPC: B23Q11/00
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce cost by reducing the sizes of a conveyor located outside a machine and a coolant tank. SOLUTION: A pair of conveyors 17 are located in a machine with their mutual distance gradually narrowed toward discharge ends 17a, and disposed symmetrically on both sides of the center line O of a spindle 2. As the in- machine conveyors 17 are disposed as described above, the distance b between their discharge ends 17 decreases naturally. Therefore, the sizes of an outside- machine conveyor 9 and a coolant tank 12 may be reduced so that their costs may be reduced. Furthermore, the reduction in the sizes of the outside-machine conveyor 9 and the coolant tank 12 reduces the installation area of the machine. Work space is widened and work is facilitated accordingly.

Abstract: PURPOSE:To additionally reduce the size and thickness of the optical head by constituting a beam separating means for separating a reflected beam and exit beam so as to commonly have a function of a polarizing means to bend the progressing direction of the exit beam by about 90 deg. and the beam separating means so as to contain the polarizing prism and polarizing circuit means. CONSTITUTION:The exit beam from a semiconductor laser 1 is polarized by a polarizing prism and is converted from linearly polarized light to circularly polarized light by passing a quarter-wave plate 6. The circularly polarized light is made incident on an information medium surface 5. The reflected beam 8 is converted from the circularly polarized light to the linearly polarized light when the beam passes the quarter-wave plate 6. At this time, the polarization direction of the reflected beam 8 is perpendicular to the polarization direction of the exit beam 7. The incident reflected beam 8 on the polarizing prism 21 is polarized in a direction exclusive of about 90 deg. from a relation between the polarization direction of the reflected beam 8 and the optical axis direction 22 of the double refractive crystal constituting the polarizing prism 21 when the reflected beam 8 is reflected by the reflection surface 23. The exit beam 7 and the reflected beam 8 are thus separated.

Abstract: PURPOSE:To smoothly pass high pressure steam above a cooling water passage to a reserve tank and to suppress counterflow by making a minimum sectional area of a passage at an entering side of the reserve tank 1.5 to 3 times as large as a minimum sectional area of a passage at a discharging side. CONSTITUTION:Orifices A, B and C are provided in three pipes 8, 9 and 10 connected to a reserve tank 3. Under the highly thermal load operation state of an engine 1, pressure in the reserve tank 3 reaches relief pressure. Since it is necessary for pressure in the upper part of a radiator 2 not to extremely exceed its withstanding pressure, namely, the relief pressure of a cap 11 even under this state, the total are of the openings of the orifices A and B at an entering side to the reserve tank 3 must be made 1.5 times or more as large as that of the orifice C at a discharging side. Since pressure at an inlet portion 12 of a cooling water pump 6 is extremely lowered to generate cavitation, pump efficiency is lowered with the decrease of the amount of circulating water and cooling performance is lowered, it is necessary to have an opening area ratio of three times or lower.
