A process for producing an aminophenol, which comprises(A) a step of reacting a dihydric phenol with an aminating reagent in the liquid state under heat in the presence of water and a water-soluble catalyst,(B) a step of removing the unreacted aminating reagent from the reaction mixture, and then precipitating the crude aminophenol from the reaction mixture from which the aminating reagent has been removed, thereby to obtain a crystallization mixture containing the crude aminophenol,(C) a step of separating the crystallization mixture into crystals of the crude aminophenol and the reaction mother liquor containing the catalyst,(D) a step of circulating part or the whole of the reaction mother liquor to the aminating step, and(E) a step of washing the crude aminophenol crystals with a washing liquor to obtain the washed crude aminophenol crystals and the washing mother liquor, and thereafter separating the aminophenol from the washed crude aminophenol crystals and purifying it.

An object of the present invention is to provide a polishing pad which enables high accuracy optical end-point detection in a state where polishing is carrying out, and which can prevent slurry leakage from a polishing layer to a cushion layer even in the case of being used for a long period. Another object is to provide a method for producing a semiconductor device using the polishing pad. The present invention relates to a polishing pad in which a polishing layer having a polishing region and a light-transmitting region, and a cushion layer having a through hole are laminated via a double-sided adhesive sheet such that the light-transmitting region and the through hole are laid one upon another, wherein a transparent member is stuck on an adhesive layer of the double-sided adhesive sheet in the through hole.

A bending apparatus for corrugating a sheet-like material can comprise a support member, a feed mechanism, a bending member, a hold-down member, and a driving mechanism. The support member can comprise a support surface with corrugations. The feed mechanism can be configured to feed the support member in increments of one pitch of the support member corrugations. The bending member can be configured to reciprocate between a retracted position and an actuated position mating with a corrugation on the support surface so material laying on the support surface is bent along the support member corrugation. The hold-down member can be configured to be reciprocated between a retracted position and an actuated position holding the material against the support surface. The drive mechanism can be configured to sequentially reciprocate the bending member and the hold-down member so the hold-down member presses down the material and the bending member bends the material.

A traffic jam guide image showing traffic jam conditions of a plurality of road sections ahead of a current location of a vehicle is displayed together with a map image during a guidance of a guide route from the current location to a destination. Based on a user operation performed on a touch screen, an object road section in which a search condition is to be changed and the search condition in the object road section are set. A second guide route from the current location to the destination is searched for based on the search condition set for the object road section such that the user has only to perform a simple operation through a touch screen to automatically change the search condition and set the road section to which the changed search condition is applied.

When image data to be encoded is divided into image data items in a plurality of hierarchies and an image data item in a given hierarchy among the divided image data items in the plurality of hierarchies is to be encoded as an intra picture, an image encoding apparatus and an image decoding apparatus provided by the invention allow improvement in efficiency of encoding the image data item in the given hierarchy. When input image data is divided into image data items in a plurality of hierarchies for encoding and a higher hierarchy image data item is to be encoded as an intra picture, a control circuit switches a switch so that reference data is supplied to a subtracting circuit. The subtracting circuit subtracts the reference data from the higher hierarchy image data item outputted from a preprocessing circuit. Encoding is performed on the subtraction result of the subtracting circuit, i.e. differential image data.

Two current electrodes 2 and 3 are arranged on a circumference of a subject 1, a distance between the two current electrodes being sufficiently shorter than a circumferential length of the subject 1. A current source 4 passes a current between the two current electrodes. A measuring electrode 5 is arranged adjacent to one of the two current electrodes 2 and 3. A measuring electrode 11 is arranged substantially opposite to the two current electrodes 2 and 3 across the subject 1. A voltmeter 7 measures a voltage generated between the measuring electrodes 5 and 11. A body fat computing unit 25 computes the quantity of subcutaneous fat 8 of the subject 1 according to the voltage measured with the voltmeter 7.
