Title: Butterfly valve with metal valve seat
Inventor: OKANO MASAMI
IPC: F16K1/228
Filed: 1980-12-26
Abstract: PURPOSE: To reduce operating force by installing an eccentric cam which is fitted on an operating shaft and a supporting shaft and fixed onto a valve body, in the butterfly valve equipped with a metal valve seat.  
     CONSTITUTION: Two eccentric cams 6 installed at both edges of a valve body 3 revolve with the valve body in relation to the valve body 3 by means of set screws 7. The cam 6 and a valve seat 2 are in noncontact state during perfect closing. In perfect opening, the cam 6 shifts the valve seat 2 in the stream axis direction towards the exit port side B against the force of an elastic member 10. As the cam 6 separates the valve seat 2 from the valve body 3 in opening operation, the sealing surfaces are cut off from contact in perfect opening. Therefore, the concave or deformation on the sealing surface due to the contact of the sealing surfaces of the valve body 3 and the valve seat 2 in perfect opening is not generated. In order to close the valve, it is enough only to operate an operating shaft 4 in the closing direction. At this time, the cam 6 gradually releases the pushing operation to the valve seat 2, then pressing operation is perfectly removed in close to the perfect opening.

Abstract: PURPOSE:To vacuum-pack a spined object using a thin flexible resin film by wrapping directly the spined object such as a hairy crab with an interior film, wrapping the interior film with an exterior film and also placing a deaerating slit at an appropriate position of the interior film. CONSTITUTION:A spined object 1 such as a hairy crab is directly wrapped by an interior film 2, and the interior film 2 is wrapped by an exterior film 9. A deaerating slit is placed at an appropriate position of the interior film 2. The interior film 2 and the exterior film 9 are formed respectively of multi- layered structures of thin resin. In deaerating this package, suction speed is delayed. In addition, the interior film 2 is sealed by an appropriate sealing means such as an adhesive tape 5 at an appropriate portion. The exterior film 9 is formed into a bag having an opening 10, wherein the spined object 1 and the interior film 2 are received from the opening 10, while air is sucked from the opening 10 for deaeration. Thus a thin resin film is used to vacuum-pack the spined object 1.

Title: Developing method for electrostatic latent image
Inventor: ARAI MITSUTAKA
IPC: G03G13/08
Filed: 1986-08-07
Abstract: PURPOSE:To permit good development without entailing the contamination in device by splashing of toners and carriers and without generating fogging by forming a developer layer to be formed on a developer conveying body as a thin layer and using the specific carrier. CONSTITUTION:The developer layer to be formed on the developer conveying body is formed as the thin layer, and the resin-coated carrier formed by coating a resin having >=HB pencil hardness on magnetic material particles is used as the carrier. The durability of the carrier is remarkably improved as the coating layer of the carrier is hard. The good developing process is executable even when the carrier is repeatedly used for many times. Since the coating layer of the carrier is hard, the tendency to the retardation of the frictional chargeability of the carrier by sticking of the toner particle to the carrier surface is decreased. The frictional charge between the carrier and toner is satisfactorily executed even if the carrier is repeatedly used many times. The generation of the weakly charged toner is thereby considerably decreased and the generation of toner and carrier splashing is prevented.
