Abstract: An adapter for mounting an optionally-additional functional component onto a mobile wireless communication device (on which a battery for electrically energizing the mobile wireless communication device is mountable), comprises a joint portion connectable to the mobile wireless communication device so that the adapter is attached through the joint portion to the mobile wireless communication device in a removable manner, and a component holding portion adapted to hold the optionally-additional functional component on the component holding portion.

Abstract: A portable telephone apparatus of folding type, having a upper side housing 1 and a lower side housing 2, and the first one being rotatable to second one through a hinge 91, wherein an antenna containing device 213 is provided in parallel beside the lower side body 2, and an antenna 3 is inserted into the antenna containing device 213 in a direction, crossing at a right angle with a line extending in an axial line of the hinge 91, and the antenna 3 is held by the antenna containing device 213, thereby enabling to attach the antenna onto the lower side housing but without increase in the thickness thereof.

Abstract: Disclosed is a safe and efficient process for producing N-polyoxy-alkylated polyamides which comprises reacting polyamide in powder form under a temperature below the melting point of the polyamide with an alkylene oxide in the presence of an alkaline catalyst, and in a medium such as specificed cyclic ethers or specified alkyleneglycol dialkyl ethers.

Abstract: An improved process for producing a macrocyclic ester compound comprises decomposing and cyclizing linear ester compounds, from high to low condensate, to the macrocyclic ester, with the addition of glycol or oligoester compound of which the component is similar as those of said linear ester compounds. By this addition the reaction proceeds easily for a long time, and its efficiency is improved.

Abstract: An ether compound is advantageously produced by an ether exchange reaction of a different ether compound and a hydroxy group containing compound in the presence of a heteropoly acid or an acidic salt thereof as the catalyst. The catalyst is novel and is extremely effective to the present process and brings about less by-products compared to other processes or other catalysts.

Abstract: Oxyalkylene group of an alkylene oxide is inserted into a chain-type ether compound having at least one lower alkyl group by reacting the latter with the alkylene oxide in the presence of a catalyst prepared by mixing boron trifluoride and/or stannic chloride with an active-hydrogen compound exemplified by water or a lower aliphatic alcohol. The reaction results reduced formation of by-product dimer of the alkylene oxide even under an increased charging ratio of the alkylene oxide to the chain-type ether.

Abstract: A process for the production of a mono- or poly-alkylene glycol diether which consists of reacting an ether having at least one lower alkyl group with alkylene oxide in the presence of a heteropoly acid or a heteropoly acid acidic salt. Heteropoly acids and their acidic salts whose ratio of the hetero and coordinate atom is 1:6 and 1:12 are preferably used.

Abstract: A process for the production of an alkylene glycol ether ester of an organic carboxylic acid which comprises the step of reacting an alkylene oxide with an ester of organic carboxylic acid in accordance with the following reaction equation: ##STR1## wherein R" is a substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms or a hydrogen atom;R'" is a substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms;R.sup.3 are each the same or different substituted or non-substituted hydrocarbon having 1 to 10 carbon atoms or a hydrogen atom;Q is simultaneously the same or different groups X, R, OR, SR, NR.sub.2 or PR.sub.2 (wherein X is a halogen atom selected from the group consisting of Cl, Br, and I, and R is the same or different substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms or a hydrogen atom, and a combination of all Q=R does not occur).

Abstract: A process for the production of an alkylene glycol ether ester of organic acid which comprises reacting an alkylene oxide and an ester of organic carboxylic acid by using a catalytic amount of a basic catalyst selected from the group of halogenides consisting of zinc, aluminum, titanium, tin and iron, and organometallic compounds of zinc, aluminum, titanium, tin and iron.
