In an apparatus for slit radiography a body (1) to be irradiated is scanned at least twice by means of a planar, fan X-ray beam (4) emitted from an X-ray source (1) via a slit diaphragm (2), the hardness of which beam increases with each next scanning motion. An X-ray detector (6) mounted behind the body collects the radiation passed, and sections of detection means (10) juxtaposed in the lon...

An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangem...

PURPOSE:To prevent a vehicle from making an abrupt start, and also prevent a transmission from being damaged because of improper operations of an inching by providing an inching pedal for a vehicle such as a fork lift and the like equiped with an automatic transmission having a mechanical clutch so as to prepare the standby condition with the first speed. CONSTITUTION:When the stroke of an inching...

PURPOSE:To enable an inching control to be effected with a definite feeling provided at all times by correcting the clutch position as the amount of feedback after the actual position of a half clutch has been detected in a controlling method for an inching of a vehicle such as fork lift and the like equiped with an automatic transmission having a mechanical clutch. CONSTITUTION:The position of a ...

PURPOSE:To prevent a creep phenomenon from taking place when a neutral position is changed over to a running position by allowing hydraulic pressure to be applied as it is to a starting clutch for the specified period of time deter mined by both the temperature and pressure of hydraulic oil before the creep control is started. CONSTITUTION:A creep prevent device includes a starting clutch 1, an en...

PURPOSE:To permit an early control to be effected with the maximum clutch engaging pressure applied at the time of starting until a clutch is conditioned to the specified half engagement by controlling a device in such a way that the maximum clutch engaging pressure is applied until the starting clutch is conditioned to the specified half engagement. CONSTITUTION:This controlling device includes a...
