Title: Ventilated disk
Inventor: KAI HIDEYUKI
IPC: F16D65/12
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a ventilated disk in which the accumulation of heat to the thick thickness part can be reduced, by providing closed recessed parts to the sliding surfaces of the axially thick thickness parts that have been formed by an outer disk, ribs, and an inner disk. SOLUTION: When both disks 2, 3 and pads are friction-engaged, friction heat and gas are produced, and the friction heat produced in both the disks 2, 3 is released outside from the respective surfaces of the outer disk 2, inner disk 3, ribs 5, and recessed parts 8 and 9, and the friction heat is not accumulated in the thick thickness parts 6. The gas produced in the pads, when the pads and the sliding surface parts 7 are frictionally engaged, is temporarily stored inside the recessed parts 8 and 9, and after the pads have passed through the sliding surface parts 7, it is released outside through the recessed parts 8 and 9, so that the occurrence of the fade phenomenon can be restrained.  Further, since the rigidity of the thick thickness part 6 is high, the deformation of the recessed parts 8, 9 is hardly produced, and even if the ventilated disk 1 is used for a long period of time, the occurrence of crack in the recessed parts 8, 9 is hardly produced.

Title: Electrostatic charge removing device
Inventor: MURAKAMI YASUO
IPC: H05F3/04
Filed: 1989-10-05
Abstract: PURPOSE:To remove electrostatic charge satisfactorily using a comparatively simple circuit by allowing a contactless terminal to confront which forms a constant electric field between electrostatically charged particles by a dielectric substance depolarized dielectrically with impression of a constant voltage, and connecting the terminal with an energy emitting means. CONSTITUTION:A contactless terminal 1 is allowed to confront which forms a constant electric field between electrostatically charged particles by a dielectric substance depolarized dielectrically with impression of a constant voltage, and this terminal 1 is connected with an energy emitting means 2. When this terminal 1 of dielectric substance depolarized dielectrically with impression of voltage is approached to the electrostatic charges either depolarized to positive or negative, or distributed with a certain potential difference into a comparatively high potential and low potential, lines of electric forces are densely generated between charged particles owing to the strong depolariztion effect of the dielectric substance, and a certain electric field is formed between the two. In the case that the energy emitting means 2 is a circuitry including a discharge capacitor, this formed electric field depolarizedly charges this discharge capacitor 2. The energy emitting means thus operates with discharge of the capacitor to achieve deelectrification.
