In a copper-based slide member in which needle-shaped Mn—Si based compounds are dispersed in a brass structure, 50% or more of a total number of the needle-shaped Mn—Si based compounds having lengths of 50 μm or more in a major axis direction are constituted of a plurality of small particles. Thereby, even if the needle-shaped Mn—Si based compounds fall off during sliding, the small particles which constitute the needle-shaped Mn—Si based compounds may fall off. Thus, the frequency of falling off of the coarse needle-shaped Mn—Si based compound which damages a shaft and a bearing is decreased. Therefore, seizure hardly occurs.

In a high-voltage apparatus according to this invention, a predetermined voltage is applied to a rotating anode after waiting until the number of rotations increases to such an extent that the rotating anode is not damaged. That is, X-rays of desired intensity are already outputted from a point of time when the voltage is applied to the rotating anode. Therefore, diagnosis can be performed immediately after the voltage is applied to the rotating anode. That is, unlike the prior art, there is no need to wait until X-ray intensity becomes suitable for diagnosis after X-ray emission is started, and there is no need to irradiate the patient with unnecessary X-rays. Therefore, the patient can be inhibited from being irradiated with excessive X-rays (with an improvement made in a response from when the operator gives instructions for starting fluoroscopy until emission of X-rays suitable for diagnosis).

The pressurized molten metal solidifies and shrinks around the bar end portions to form an endring for the rotor. The core, endring and arbor are inverted and confined in the mold, and the casting steps are repeated to form the opposite endring.

In cities across America, black men are on the run. On April 4, 2015, in South Carolina, Walter Scott was killed while running away from a police officer. Eight days later, Freddie Gray ran from police in Baltimore. He was caught and later died in custody.

On this episode of Reveal, we explore the consequences of fleeing from the police through two stories, both set in Baltimore.

Some police departments are embracing a set of tactics designed to reduce the use of force – and prevent police shootings. Rather than rushing in aggressively, officers back off, wait out people in crisis and use words instead of weapons.

But this training isn’t required in most states. Reveal teams up with APM Reports and finds that most cops spend a lot more time training to shoot their guns than learning how to avoid firing them.
