摘要:
A disc brake designed to prevent formation of a pressure recess caused by a braking operation when a vehicle is moving forward, and reduce rattling caused by a braking operation when the vehicle is moving rearward. The disc brake comprises: a caliper body including pistons that are disposed in opposing relation to each other on either side of a disc; and a plurality of brake pads that are disposed in pairs on either side of the disc. The caliper body is provided with: forward torque-receiving surfaces for receiving a braking torque from the brake pads during a braking operation when the vehicle is moving forward; and rearward torque-receiving surfaces for receiving a braking torque from the brake pads during a braking operation when the vehicle is moving rearward. Only the forward torque-receiving surfaces are provided with guide members for abutment with the brake pads, while the rearward torque-receiving surfaces can be brought into direct contact with the brake pads. The caliper body is made of a material having a hardness lower than that of the guide members.

In a ceiling embedded type indoor unit for an air conditioner, an wind sound is reduced while preventing a beat sound of blowers with keeping a high air conditioning capacity. In the ceiling embedded type indoor unit provided with a U-shaped heat exchanger which is placed in a casing embedded in a ceiling and is constituted by two side portions and a bottom portion connecting the side portions at one end side, blowers arranged in an inner space of the heat exchanger, a decorative panel mounted to a lower surface of the casing and having two elongated air outlet ports in correspondence to the side portions of the heat exchanger and an air suction port formed between the air outlet ports, and a control apparatus, the control apparatus controls so that the number of rotation of the blower near a valley portion of the U-shaped heat exchanger becomes high and the number of rotation of the blower near the open end of the U-shaped heat exchanger becomes low.

A shift control system of an automatic transmission executes an interchange shift by interchanging engagement conditions of first and second friction elements of the automatic transmission. The first and second friction elements are engaged and disengaged according to oil pressures supplied thereto. A controller of the shift control system is arranged to decrease the second oil pressure of the second friction element by a second predetermined gradient and to increase the first oil pressure of the first friction element by a first predetermined gradient after the loss stroke of the first friction element is terminated, and to determine the first gradient such that a difference between a command pressure and an actual pressure of the first friction element is kept substantially constant.

The invention relates to a polyether polyol, a water-curable polyurethane prepolymer prepared by using the polyether polyol, and a composition containing the prepolymer. The above polyether polyol is obtainable by subjecting an active hydrogen compound to addition polymerization reaction with ethylene oxide and an alkylene oxide of 3 to 4 carbon atoms in a specified ratio. The above water-curable polyurethane prepolymer is obtainable by reacting the polyether polyol with a polyisocyanate compound. The above composition comprises a mixture of the water-curable polyurethane prepolymer and the polyisocyanate. The above water-curable polyurethane prepolymer and composition provide a foam of fine and uniform cell structure with improved strength on curing with water.

A refrigerant flow control system associated with a refrigerant circulating circuit having a compressor, a condenser, an expansion valve and an evaporator, includes a branch pipe extending from a discharge pipe of the compressor and having on sealed free end. A first temperature sensor is disposed on the branch pipe near the sealed free end for detecting a condensation temperature of a refrigerant which is condensed in the branch pipe. A second temperature sensor is disposed on the discharge pipe of the compressor for detecting a temperature of the gaseous refrigerant discharged from the compressor. The signals representative of the condensation temperature and the temperature of the discharge gaseous refrigerant are inputted to a control device. The control device calculates a difference between the two detected temperatures, and a degree of superheat of the discharged gaseous refrigerant and transfers to the expansion valve a command signal representative of the calculation results, thereby controlling an opening of the expansion valve.

An angle detecting device has a combined structure of plural resolvers, but is simple and is easily produced, and has redundancy reducing the risk of failure. The angle detecting device has two resolvers which are combined in the axial direction and has a stator core 100. The stator core 100 is formed by laminating a first stator core 103 on a second stator core 104. The first stator core 103 is provided with plural salient poles 101 which extend to a center of an axis. The second stator core 104 is provided with plural salient poles 102 which extend to the center of the axis. The salient poles 101 and 102 differ in position when viewed from the axial direction, and the salient poles 102 are positioned between the adjacent salient poles 101 when viewed from the axial direction.
