Title: Crushing pump
Inventor: UMEHARA KATSUO
IPC: F04C2/344
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To effectively transfer solid matter and liquid at sufficiently large discharge pressure by constituting a transfer means of a positive displacement pump in a crushing pump. SOLUTION: This crushing pump 21 is provided with a crushing means 2 for crushing solid matter in liquid and a vane pump 22 (a transfer means, a positive displacement pump) for transferring both the liquid and the solid matter. The vane pump 22 is installed on the downstream side of the crushing means 2 and is connected to a casing body 11 through a discharge casing 9. This vane pump 22 is a positive displacement pump, which is provided with a pump casing 31, an annular liner 32 fixed thereto, a rotor 33 rotating around a position eccentric to the liner 32, and a vane 34 fitted thereto.  Since the solid matter and the liquid are thus transferred by the vane pump 22 which is the positive displacement pump, even if concentration of the solid matter is heightened or viscosity of the whole liquid including the solid matter is increased, these solid matter and liquid are surely transferred to the next process.

Title: Automatic developing device
Inventor: SHIDARA SHINICHI
IPC: G03D3/00
Filed: 1988-12-28
Abstract: PURPOSE:To enable fast processing by irradiating a film which is conveyed in processing liquid from below after preheating the film. CONSTITUTION:The film 12 is sent by rollers 26 and 28 to move in a processing tank 20. The feed roller 26 at the entrance side of the processing tank 20 is a heat roller, so the film 12 is heated up to proper temperature when pressed by the roller 26 and sent. A vibrator 10 generates the ultrasonic wave of constant frequency with constant energy and this ultrasonic wave strikes the film 12 slantingly. Consequently, the film 12 moves in an ultrasonic wave irradiation area including a center axis X by a distance larger than the strong/weak period intervals of the ultrasonic wave and is not affected by the periodic level variation of the ultrasonic wave. Consequently, the processing process of the film 12 can be shortened.
