A compressor assembly becomes a compressor as a result of a terminal guard being attached. The compressor assembly includes a body, and a terminal guard mounting seat attached to an outer surface of the body. The terminal guard is attachable to the terminal guard mounting seat. A compressor includes the compressor assembly and the terminal guard. The compressor can be manufactured by attaching the terminal guard mounting seat to the outer surface, administering metal spraying to at least part of the outer surface after attaching the terminal guard mounting seat, and attaching the terminal guard to the terminal guard mounting seat after the administering metal spraying.

Compressor assembly, compressor, and method of manufacturing compressor

A compressor includes a casing, a compression mechanism, and a motor that drives the compression mechanism. The casing is configured to cover an internal space. The internal space includes a first space and a second space larger than the first space. The casing has a first casing part covering the first space and a second casing part covering the second space. At least one of the first space and the second space is a high-pressure space configured to contain high-pressure fluid. A metallic coating may be formed on an outer surface of at least the first casing part. Alternatively, a resin coating may be formed on an outer surface of the casing.

Compressor for refrigerating machine

A compressor includes a casing and a metallic coating. The casing includes a low-pressure casing part covering a low-pressure space and a high-pressure casing part covering a high-pressure space. The metallic coating is formed at least on a part of an outer surface of the casing. The metallic coating includes a low-pressure part coating formed in the low-pressure casing part, a high-pressure part coating formed in the high-pressure casing part, and a welded part coating formed in a welded part. At least either the average thickness of the low-pressure part coating or the average thickness of the welded part coating is greater than the average thickness of the high-pressure part coating.

A lubricating coating which can prevent the occurrence of galling even when makeup is carried out with a high torque and which has excellent rust preventing properties is formed on the contact surfaces of a pin and/or a box of a tubular threaded joint. The lubricating coating contains copolymer particles made from particles of an acrylic-silicone copolymer with an average particle diameter of 10-50 &#x3bc;m dispersed in a highly viscous matrix made from a mixture of a rosin-based substance selected from rosin and its derivatives, wax, a metal soap, and a basic metal salt of an aromatic organic acid (such as highly basic Ca sulfonate).

An apparatusfor evaluating the performance of a threaded joint for oil country tubular goods using a first steel pipe Pand a second steel pipe Phas a basewhich holds a first steel pipe Pin an upright position with an upper end of the first steel pipe Pextending above the base and the remainder partly disposed under ground. A support membermounted on the baseextends alongside the first steel pipe P. A second steel pipe Pis suspended above the first steel pipe Pby a suspending mechanism. A threaded joint can be connected and disconnected by first and second tongsandwhich rotate the second steel pipe Pwith respect to the first steel pipe P. A stabilizermounted on the support membercan limit the radius of gyration of the second steel pipe P

Test apparatus for a threaded joint for oil country tubular goods

A protector which prevents damage to a solid lubricating coating on a threaded portion of a threaded joint when the protector is mounted on a pin or a box of a threaded joint for pipes in which at least one of the pin or the box is lubricated with a solid lubricating coating comprises a tubular member having a threaded portion on its inner or outer peripheral surface which threadingly engages with at least a portion and preferably 3-5 complete threads of the threaded portion provided on the pin or the box to be protected. The thread height Hof the threaded portion of the protector and the thread height Hof the complete thread of the pin or the box on which the protector is mounted satisfy HH, and the difference between Hand H[=HHis larger than the maximum coating thickness at the thread crest of the solid lubricating coating which covers the threaded portion of the pin or the box.

Protector for tubular threaded joint

A lubricating coating which is free from harmful heavy metals is formed on a premium threaded joint for pipes constituted by a pin and a box each having a contact surface comprising a threaded portion and an unthreaded metal contact portion (a sealing surface and shoulder) in order to provide the joint with galling resistance, gas-tightness, and anticorrosive properties such that the unthreaded metal contact portion is prevented from yielding even when the joint is made up with a high torque. The lubricating coating comprises one or both of a rosin and calcium fluoride; metal soap; wax; and a basic metal salt of an aromatic organic acid, and preferably it further includes a lubricating powder, magnesium carbonate, and/or a carbohydrate, particularly a cyclodextrin.

Threaded joint for pipes having a lubricating coating

A holder for a mobile electronic device includes first and second clamping jaws, at least the first clamping jaw being displaceable toward the second clamping jaw to clamp the mobile electronic device. The holder also includes a stop element and an entraining element connected to the first clamping jaw, the entraining element being shaped so that it is displaceable with respect to the stop element, namely jointly with the clamping jaw connected to it, in which case at least one extreme position corresponding to the maximum opening of the clamping jaw is defined in the displacement path by the impact of the stop element against the entraining element. The holder includes a damper element, which is mounted on the stop element and damps the stopping of the stop element against the entraining element.

Mobile device clamp holder with damped release mechanism

An emergency braking system for a vehicle driven by an electric motor. The vehicle includes a manually operable accelerator lever, a displacement detector for detecting displacement of the accelerator lever, an emergency detector disposed in a region of the accelerator lever for detecting an operating force applied to the accelerator lever, a braking device, and a control unit for receiving detection signals from the displacement detector and emergency detector, and outputting control signals to the electric motor and braking device. The control unit outputs the control signal to the braking device to brake the vehicle when the operating force detected by the emergency detector exceeds a predetermined value. In addition or as alternative to the emergency detector, the vehicle may include an emergency detector disposed in a driver's foot rest region for detecting a treading force of the driver.

Braking control system for a vehicle driven by an electric motor

An electric vehicle that runs at a speed controlled by adjusting power supply to an electric motor in response to a speed setting signal from a speed setting device including an accelerator lever and a change speed lever. This vehicle comprises a first control unit for producing a target speed value based on the speed setting signal, a second control unit for controlling the electric motor, and a rotary encoder for detecting an actual vehicle speed from rotation of the electric motor and feeding the vehicle speed back to the first and second control units. The first control unit compares the target speed value and actual vehicle speed and, when a difference therebetween exceeds a predetermined value, varies the target speed value for application to the second control unit. The second control unit compares the target speed value and actual vehicle speed and determines an amount of power supply to the electric motor.
