Abstract: This disc brake includes a cylinder bore into which a piston is fitted, a seal groove provided in the cylinder bore as an annular groove, and a seal member which has a rectangular cross section shape and which is fitted into the seal groove and seal a space between the piston and the cylinder bore. The seal groove includes a bottom surface portion, a side surface portion, and a chamfered portion. The chamfered portion is formed to expand an opening of the seal groove in the axial direction of the cylinder bore and has two types of curvature radii (r1 and r2).

Abstract: A friction pad mounted on a disk brake includes a back plate, and a lining attached to the back plate and configured to frictionally contact a disk. A spring member, configured to bias the friction pad toward a disk rotationally exiting side, is provided to an ear portion of the back plate. The spring member includes an attachment portion attached to the back plate, an extension portion extending from an end portion of the attachment portion, and an abutment portion folded back from the extension portion and extending in a direction toward the disk. The abutment portion is configured to receive a reaction force from a torque reception surface by abutting against the torque reception surface at a position on an opposite side of the ear portion from the disk when the ear portion and the torque reception surface of a mount member abut against each other.

Abstract: A disc brake that suppresses braking noises when a vehicle moves backward include an urging spring urging a friction pad toward a rotationally exiting side of a disc when the vehicle moves forward, the urging spring being arranged between a hook portion of the friction pad and a torque receiving portion of a carrier. The urging spring formed through bend of an elastic plate material has its spring constant that is set to be a small value to avoid resonance frequency causing noise where the base end side thereof is fixed to the hook portion of the backing plate while the top end side thereof elastically abuts to the torque receiving portion of the carrier. The urging spring is located at the position that is outside in the radial direction from the center position of the hook portion in its width direction.

Abstract: There is provided a liquid crystal display device having a longer useful life and in which its so-called picture frame area can be narrowed. The liquid crystal display device includes a liquid crystal display panel having a display part in its central portion and a backlight disposed on a back side of the liquid crystal display panel. The backlight includes a discharge tube having electrodes at least at its opposite ends, and the electrodes are disposed at the exterior of the discharge tube. The opposite end portions of the discharge tube where the respective electrodes are disposed are positioned to be superposed on the periphery of the liquid crystal display panel and are bent with an angle with respect to the central axis of the discharge tube.

Abstract: A shoulder belt anchor adjusting device comprises an adjusting unit supported on a side pillar of a vehicle so as to be movable in substantially vertical directions along the side pillar, and having a stud bolt as a shoulder belt anchor support projection projecting toward the interior of the cabin of the vehicle; and a shoulder belt anchor unit detachably mounted on the stud bolt of the adjusting unit, and having an anchor member through which a seat belt is passed. The stud bolt is provided with an engagement groove in its head portion, the shoulder belt anchor unit is provided with a latch member or members which engage with the engagement groove in a spring action to hold the shoulder belt anchor unit on the adjusting unit, when the shoulder belt anchor unit is moved toward the adjusting unit along the axis of the stud bolt. It is not necessary to remove a cover of the shoulder belt anchor unit before the anchor unit is assembled with the adjusting unit.

Abstract: Disclosed is a switching power source having a series connection composed of a main transformer, a current-suppressing inductance element, and a switching element and connected across a DC input power source, in which output windings are additionally wound on the main transformer and the inductance elements respectively and those output windings are connected in series to each other so as to form an auxiliary power source for a control circuit for driving/controlling the ON-OFF of the switching element, and a starting circuit is provided to supply power from the DC input power source to the control circuit only during the starting time of the switching power source.

Abstract: A switching power supply, in which a series circuit consisting of a primary winding of a transformer and a controllable switch is connected with a DC power source and a secondary winding of the transformer is connected with a first voltage source outputting the voltage developed across the secondary winding during the on-period of the controllable switch and a second voltage source storing the exciting energy of the transformer during the off-period of the controllable switch by using the exciting inductance of the transformer as a current source, a series circuit consisting of the first and the second voltage sources being connected with a load. Owing to this construction, even if voltage-current characteristic of a load having constant voltage characteristic, such as a magnetron, vary due to variations in the temperature, etc., the output voltage is automatically compensated and a stable electric power can be supplied to the load.
