Filed: 1990-02-23
Abstract: PURPOSE:To prevent the passage of solid impurity to be removed through a filter, in a ceramic filter obtained by forming filtering flow paths between aggregate particles in a reticulated state, by using a raw material with a shape factor SF of 120 or less as aggregate particles. CONSTITUTION:A ceramic filter is obtained by bonding a large number of aggregate particles by an inorg. binder to form filtering flow paths between the aggregate particles. As the aggregate particles, a raw material whose shape factor SF defined by formula I (wherein SF1 is represented by formula II, SF2 is represented by formula (III), SF3 is represented by formula (IV), M is the max. diameter of the projection figure of aggregate particles, P is the peripheral length of the projection figure of aggregate particles, B is the max. width in the direction crossing the max. diameter of the projection figure of aggregate particles at a right angle and A is the area of the projection figure of aggregate particles) is 120 or less is used.

Title: Heat resistant alloy for centrifugally cast pipe
Inventor: TAKAHASHI EIJI
IPC: C22C38/48
Filed: 1981-03-24
Abstract: PURPOSE: To reduce the crack sensitivity of the weld heat-affected zone of a heat resistant alloy contg. C, Cr, Ni and Nb without deteriorating the mechanical characteristics by restricting the Nb content to a relatively low range and relatively increasing the C content.  
     CONSTITUTION: The composition of this alloy is composed of, by wt., 0.35W 0.50% C, <1.0% Si, <1.0% Mn, 23W26% Ni, 23W26% Cr, 0.8W1.4% Nb and the balance Fe with inevitable impurities. Nb enhances the creep rupture strength by the formation of carbide but increases the crack sensitivity of the weld heat- affected zone, so the Nb content is restricted to said low range while preventing the deterioration of the mechanical characteristics. since the crack sensitivity of the weld heat-affected zone is considerably reduced by increasing the C content when the Nb content is low, the C content is set in said range in which the original hardening action of C is not remarkably developed.

Title: Dry dehumidifying material
Inventor: YOKOTA HISAAKI
IPC: B01D53/26
Filed: 1987-02-25
Abstract: PURPOSE:To prevent a chemical adsorbent from being flowed out and scattered even when high-moisture gas is introduced and to enable dehumidification at low dew point by stepwise increasing the concn. of the chemical adsorbent and impregnating a honeycomb structural body therewith. CONSTITUTION:A honeycomb structural body forming a dehumidifying agent consists of material having a regenerable physical adsorbent such as silica gel as a main component and contains >=85wt.% silica gel component excepting a chemical adsorbent. This honeycomb structural body is impregnated with chemical adsorbent such as lithium chloride but in this case, the concn. is increased stepwise toward an outflow port side of moisture-contg. gas from an inflow port side thereof. By such way, for example, even if high-moisture gas is introduced, a certain quantity or more of moisture is not adsorbed the inflow port side, and the outflow and scattering of the chemical adsorbent are not caused. Further excellent dehumidification performance can be realized by regulating the impregnated amount of the chemical adsorbent to maximum quantity in the outflow port side of moisture-contg. gas.
