An electric brake device includes an electric motor, a braking force application mechanism, a lock mechanism, a temperature sensor for measuring an ambient temperature of a vehicle in which the electric brake device is provided, and a freezing preventive power supply unit. The freezing preventive power supply unit initiates the supply of an electric power to the electric motor or a drive source of the lock mechanism in the event that while the braking force application mechanism applies a braking force and the lock mechanism is held in a locked condition, the temperature sensor detects a preset temperature of the electric brake device immediately before freezing.

An electric parking brake system includes an electric motor; a linear motion mechanism that converts the rotational movement of a rotor shaft of the electric motor to a linear movement of a slide member to operate a brake; a locking mechanism that fixes a position of the slide member; a control device that controls the electric motor and the locking mechanism; a brake load estimation unit that estimates a brake force; and an electric parking brake operation instruction device that is arbitrary operable. The control device automatically executes a parking brake operation when a stop state of the vehicle is detected even if the electric parking brake operation instruction device is not operated. The automatically applied parking brake force is set to a value smaller than the normal parking brake force applied by the parking brake operation instruction device.

The pattern forming method includes forming a catalyst film on a base layer having an uneven surface, wherein the catalyst layer is formed along the uneven surface of the base layer; forming a coating film by coating a fluid material on the catalyst film; forming an insoluble layer which is insoluble in a solvent in the coating film by reacting the coating film along the catalyst film; and maintaining the insoluble layer by removing an unreacted portion of the coating film by using the solvent.

A file is formed by coating a substrate with a film-forming composition including a compound having an alicyclic hydrocarbon structure and irradiating the coated composition with microwaves having a frequency of 5.8 GHz. An insulating film is formed by irradiating a film including a compound having a siloxane structure with microwave having a frequency of 5.8 GHz. These films possess excellent film properties such as dielectric constant and mechanical strength.

The object is to provide a sealed rolling bearing which has high sealability sufficient to substantially completely prevent entry of muddy water.The radially outer portion of the seal member 5 is fitted in each of a pair of seal grooves 7 formed in the radially outer surface of an outer ring 1 at both ends thereof. A seal lip 12 formed at the radially inner portion of each seal member 5 is brought into elastic contact with an inner seal surface 10 of each of annular grooves 9 formed in the radially outer surface of an inner ring 2 at both ends thereof. The contact portion X of the seal surface 10 that is in elastic contact with the seal lip 12 has a circumferential flatness A of 5 to 20 μm. With this arrangement, it is possible to improve sealability at the contact portions, thereby preventing entry of e.g. muddy water into the bearing.
摘要:
In the present invention, a coating solution containing polysilazane is applied to a substrate to form a coating film. Thereafter, an ultraviolet ray is applied to the coating film formed on the substrate to cut a molecular bond of polysilazane in the coating film. Then, the coating film in which the molecular bond of polysilazane has been cut is oxidized while the coating film is being heated. Then, the oxidized coating film is baked at a baking temperature equal to or higher than a heating temperature when the coating film is oxidized.

To provide a machine component with an IC tag affixed thereto, in which with the IC tag having an increased storage capacity, the IC tag can be mounted with no difficulty and, also, reading or writing of information from or in the IC tag, respectively, can be facilitated. A plurality of IC tags 2 are attached to a machine component, which forms a part of a rolling bearing assembly 1, or to a machine component and an accessory with division made therebetween. Those plural IC tags 2 have different information stored therein. Where the machine component is a retainer incorporated rolling bearing assembly 1, those plural IC tags are attached to a roller retainer 5 at respective locations symmetrical with each other about the axis O of rotation thereof.

A process liquid supply nozzle comprises a substantially tubular main nozzle provided with a discharge port for discharging a coating liquid, a substantially bowl-shaped nozzle holder provided with a through-hole into which the main nozzle can be inserted, and a free space formed between the inner circumferential surface of the nozzle holder and the outer circumferential surface of the main nozzle, at least a prescribed cleaning liquid being supplied into the free space. The nozzle holder or the nozzle is relatively movable in the vertical direction such that the coating liquid is discharged from the discharge port under the state that the discharge port of the main nozzle projects downward from the through-hole, and the nozzle is cleaned with the cleaning liquid under the state that the nozzle is housed in the nozzle holder.
摘要:
Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. A step of gelling after the wafer W is carried into an aging unit is divided into several steps. Until a temperature of the wafer W reaches a predetermined treatment temperature, an average concentration of the solvent component in a mixed gas is gradually raised relative to the temperature of the wafer W. Thereby, immediately after the wafer W is transferred into a sealed chamber, the gas of the solvent component is prevented from condensing.

A sealed rolling bearing has sealing devices with both the functions of high sealing ability and small sliding resistance, which are antipodal to each other. The sealed rolling bearing has an outer member (1, 30) formed with an outer raceway surface (8, 29) on its inner circumferential surface. An inner member (4, 5, 32) is formed with an inner raceway surface (9a, 9b, 31) on its outer circumferential surface. The inner raceway surface (9a, 9b, 31) is arranged opposite to the outer raceway surface (8, 29). Rolling elements (10, 34) are freely rollably contained between the outer and inner raceway surfaces. Sealing devices (12, 13, 35) are arranged in an annular space formed between the outer and inner members (1, 30 and 4, 5, 32). Each of the sealing devices (12, 13; 35) has elastic sealing lips (27a˜27c, 23˜25, 37a, 37b). The maximum height Ry or Rmax of the surface roughness of a sliding surface of a member of the rotational side (18, 4, 32), which the sealing lips (27a˜27c, 23˜25, 37a, 37b) slidingly contact, is limited to a value of 2.0 μm or less. The run-out of the sliding surface, normal thereto, is limited to a value of 30 μm or less.
