Abstract: Disclosed is a transmission apparatus so adapted that extended-cells of variable-length cell can be handled. To accomplish this, the apparatus includes a receiver for receiving a frame signal from a transmission path; a demultiplexing/demapping unit for demultiplexing and demapping extended-cells from a payload of the frame signal received from the transmission path; a cell synchronizer for executing cell synchronization processing to identify a boundary of an extended-cell; a controller for subjecting an extended-cell to switching and other control; a multiplexing/mapping unit for multiplexing and mapping an extended-cell, which is output from the controller, onto a payload of a frame signal; and a transmitter for transmitting this frame signal to a transmission path.

Abstract: Disclosed herein are a process for producing acicular goethite particles comprising the steps of: blowing an oxygen-containing gas into a ferrous salt reaction solution containing colloidal ferrous hydroxide or iron-containing colloidal precipitates which is obtained by reacting an aqueous ferrous salt solution with less than one equivalent of an aqueous alkali hydroxide solution and/or an aqueous alkali carbonate solution based on Fe.sup.2 + in said aqueous ferrous salt solution so as to oxidize said colloidal ferrous hydroxide or iron-containing colloidal precipitates and to produce acicular goethite nucleus particles, adding to the resultant aqueous ferrous salt reaction solution containing said acicular goethite nucleus particles not less than one equivalent of an aqueous alkali carbonate solution based on Fe.sup.

Abstract: A hair nature measuring instrument comprises a hair catching portion, a rotational handle portion for rotating the hair catching portion, a rotation transmitting element having a restoring resilient force and interconnecting the hair catching portion and the rotational handle portion, and a grip portion for loosely circumscribing the rotation transmitting element. The nature of hair (hardness) is measured based on a correlation between the amount of rotation of the rotational handle portion and the amount of rotation of the hair catching portion when the hair catching portion already catching hair is rotated by the rotational handle portion.

Abstract: .alpha.-mono(methyl-branched alkyl) glyceryl ethers represented by the formula ##STR1## where m is an integer of 2 to 14, n is an integer of 3 to 11, and the total of m+n is 11 to 17, are disclosed along with skin care compositions containing the same as emulsifiers.

Abstract: Disclosed herein is a novel 2,3-dialkoxypropyl glyceryl ether and the preparation process for it. The above diglycerin dialkyl ether is readily prepared with high yield and purity by reacting its corresponding glycidyl ether with a protected glycerin to form a 1,3-dioxolan compound, followed by etherifying the thus formed 1,3-dioxolan compound into a dialkyl ether dioxolan compound, and then hydrolyzing the resultant dialkyl ether dioxolan compound. This diglycerin dialkyl ether is useful as an emulsifier, cleaner etc., and is preferably used as a component of cosmetic compositions. A cosmetic composition comprising the above 2,3-dialkoxypropyl glyceryl ether is also disclosed.
