摘要:
A distributing valve device for a heat accumulation type combustion system comprising a stationary valve mounted on an underside of a housing having six or more passages defined by partition walls provided therein at predetermined intervals, and having heat accumulators arranged in the passages, the stationary valve having six or more openings formed therein at an equal interval in circumferential direction of the stationary valve which communicate with the respective passages, and a rotary valve disposed in opposed relation on the stationary valve and having an exhaust gas supply opening, a treated gas discharge opening, and a purge gas supply opening formed therein sequentially in this order and at predetermined intervals in a direction of rotation of the rotary valve, wherein a seal member is arranged on a surface of the stationary valve in opposed relation to the rotary valve such that the seal member surrounds the each opening of the stationary valve, and a closed portion defined between the adjacent openings of the rotary valve by making an area of the closed portion larger than an area surrounded by the seal member surrounding the each opening of the stationary valve.

A cover includes an inner cover and an outer cover. The inner cover is fastened to a frame of an image forming apparatus and has integrally formed reinforcing ribs for improving strength and at least one outer cover mounting part. The outer cover has at least one mounted part which is mounted to the outer cover mounting part and possesses an outer surface which is exposed to the outside when the mounted part is mounted to the outer cover mounting part.
摘要:
Hydrazine hydrate is prepared by charging an aqueous or ketone solution of ketazine or hydrazone into a ketone recovering means, supplying the resultant solution to at least two hydrolysis reactors one after another, supplying the resultant hydrolyzed solution to an upper portion of a means for recovering hydrazine hydrate, and thereafter recovering hydrazine hydrate as an end product.

A manufacturing method of an optical device includes an optical component housing operation S1 for housing a plurality of optical components in a casing body, an optical component positioning operation S2 for adjusting the positions of the optical components by shifting the optical components to position by positioning members at predetermined positions on an illumination optical axis of a light beam irradiated by a light source, and an optical component position fixing operation S3 for fixing the positions of the optical components on the casing body after the optical component positioning operation S2. The optical component housing operation further includes a positioning member inserting process for inserting the positioning members to holes on the casing body, an optical component housing process for housing the optical components in the casing body, and a positioning member abutting process by which the positioning members abut on the optical components.

摘要:
An automobile air-conditioner wherein a controlled variable used to determine the control mode of a component of the air-conditioner is corrected or restricted according to the amount of shifting of the head part setting temperature for driving the component of the air-conditioner based on the corrected or restricted controlled variable. With this arrangement, an occupant of the automobile senses an enhanced change of the air-conditioning operation when the head part setting temperature is changed.
摘要:
A bonding composition for incombustible fibrous materials comprising (a) a water-soluble polymer containing hydrazide groups or its adduct with a water-soluble alkaline earth metal salt of an inorganic acid and (b) a heavy metal ion capable of forming chelate with the water-soluble polymer or its adduct. The bonding composition is employed as bonding agents to prepare incombustible sheet materials from incombustible fibrous materials by adding the components (a) and (b) to an aqueous dispersion of the fibrous materials and forming sheets or by forming wet or dry sheets containing the component (b) and then making the component (a) contain in the sheets. The bonding composition has excellent bonding effect and the polymer itself becomes incombustible, so incombustible sheet materials having excellent strength can be economically obtained.
