Abstract: PROBLEM TO BE SOLVED: To provide the treatment which enables novel utilization of a powdery cement raw material and by which the concn. of alkali, chlorine, etc., in a powdery raw material to be recharged can be reduced and also, the effectiveness in removing alkali, chlorine, etc., generated from a cement production equipment can be enhanced. SOLUTION: In this treatment, a powdery cement raw material is charged from a chute 24 into a rotary kiln 22 through a cyclone 21b. A waste gas generated from the rotary kiln 22 rises upward through a duct 26d, each of cyclones and other ducts and is discharged. According to the amounts of alkali, chlorine, etc., sticking to the powdery raw material, portions of the powdery raw material are separately withdrawn from dampers 38 to 40 and each of the withdrawn portions of the powdery raw material is cooled and classified.  At this time, the classification is performed with a 20μm particle size as the reference standard, namely, of each of the withdrawn portions of the powdery material, only a powder having <=20μm particle size is for example, washed with water and the other powder having >20μm particle size is taken out from a classifier 100 and the taken-out amount is normally about 60% of the amount of the classified powdery raw material and this taken-out powder is recharged. Further, the powder having <20μm particle size can be used as a solidifying material or reclamation material without washing the powder with water and also, each of the above withdrawn portions of the powdery material can be used as a solidifying material or reclamation material without classifying the withdrawn portion.

Title: Silencer
Inventor: KURATA KOUICHIROU
IPC: F02M35/16
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To improve a silencing effect without enlarging a resonator, by making a linear-shaped part of an intake pipe adjacent to a car body frame. SOLUTION: A linear-shaped part 2c of an intake pipe 2 is made adjacent to a part where a closed chamber 9 of a car body frame 3 is formed, to respectively form holes 11, 12 in this adjacent part, and the closed chamber 9 communicates with the intake pipe 2. When air passes through the intake pipe 2, inside the closed chamber 9 resonates to damp energy of sound of specific frequency, so as to reduce an intake air sound of an engine. Reduction of an intake air sound is accomplished by using the conventionally provided car body frame 3 and floor panel 6, so as to eliminate necessity for newly ensuring a large space. A position of a partitioning plate 8 is changed to suitably set the volume of the closed chamber 9, so that a silencing effect can be improved.  Since the linear-shaped part 2c is arranged adjacently to the car body frame 3, communication of the closed chamber 9 with the intake pipe 2 can be attained without using a long pipe, to be able to attain compactness of a device.

In this way, the light source 10 becomes ON only when the finger 20 has been brought into contact with the transparent plate 11, and in a state of OFF when the single is not brought into contact, therefore, no laser light is leaked to the outside. In this way, the safety is raised.
