Abstract: An optical device for viewing an object at a range of working distances. The device comprises a slender tube of a certain length and having a distal end and a proximal end. The device further comprises an imaging system disposed at the distal end and having a wide viewing angle. The device also comprises a telescopic system associated with the proximal end and having a narrow viewing angle. The imaging system is designed to form an image of the object at an image plane located on the device's optical axis and within the tube closer to the distal end than to the proximal end. The telescopic system is designed to enable viewing of the image of the object. The device is especially adapted to function as an endoscope in medical applications and may be disposable.

Abstract: An agonist or antagonist of glutamic acid or an allosteric modulator is screened by reacting a glutamic acid receptor protein having the following properties with a substance binding thereto in the presence of a test substance and detecting the inhibition or promotion of the reaction: (A) it has a transmembrane domain and an intracellular domain common to those of type 4 metabotropic glutamic acid receptor protein, or (B) it has an extracellular domain by about 316 or 327 amino acid residues shorter than that of the type 4 metabotropic glutamic acid receptor protein.

Abstract: The present invention relates to an encryption method for encrypting information including a series of multiple unit blocks, one at a time, a decryption method for decrypting multiple encrypted unit blocks, one at a time, and a recording and reproducing apparatus that uses those methods. The seed of an encryption key for encrypting each unit block and the seed of an encryption key for decrypting each encrypted unit block, which are used by those methods and the recording and reproducing apparatus, are based on a unit block that is one or more unit blocks before the current unit block in a reproduction order or on information generated by encrypting one or more unit blocks before the current unit block. Alternatively, the seed of an encryption key for encrypting each unit block and the seed of an encryption key for decrypting each encrypted unit block are information based on an encryption key for encrypting a unit block before the current unit block in a reproduction order.

Abstract: With two consecutive product-coded ECC blocks, EB1 and EB2, as a set, the rth row of first ECB block EB1 is followed by the rth row of second ECC block EB2 in such a way that the first row of first ECC block EB1 is followed by the first row of second ECB block EB2, which is followed by the second row of first ECC block ECB1, which is followed by the second row of second ECC block EB2, and so on, to interleave data on a row basis. That is, data of two ECC blocks, EB1 and EB2, is allocated alternately on a row basis. This allocation method allows an error to be distributed after reproduction even when a serious burst error extending 18 rows occurs in an ECC block.

Abstract: An injection molding machine comprises a pre-pressure addition means 2 adding a pre-pressure B acting in the opposite direction of a molding material pressure A received by a screw 1 to a detection means 3 and/or the screw 1, the detection means 3 detecting the axial pressures A and B of the screw, and a screw movement control means 4 controlling the axial pressure based on a different between the pre-pressure B and the molding material pressure A, wherein the pre-pressure addition means 2 is made non-contact with the direction means 3, a forward and backward driving motor 17 is disposed adjacent to a heating cylinder 10, and a screw connector 21 at the rear end of the screw 1 is spline-connected inside a rotating rotor of a screw rotating motor 12. According to the machine, the molding material pressure received by the screw can be accurately detected without being affected by the wear of the machine so as to properly control the axial pressure of the screw and to make the machine compact.

Abstract: A method for for comparing between an orthodontic element's actual position on the surface of a tooth and a proper position comprise monitoring the element, the tooth or both once the element and the tooth are proximal to one another by an image acquisition unit which transmits an image to a screen that displays the image and displaying information on the screen regarding proper position of the element in a manner allowing to compare between the actual and the proper position is disclosed. Further disclosed is a system and device for positioning of an orthodontic element or a marking device having a marking member for marking a position for subsequent placement of an orthodontic element on a surface of a tooth.

Abstract: A method and device are presented for measuring the electrical properties of a specimen. The specimen is excited with high energy radiation to cause emission of internal charged particles from the specimen. Electrical power is supplied to a circuit, that is formed by the specimen and any added component connected to a back contact of the specimen. The electric power supply includes at least one of the following: irradiating the circuit with low energy charged particles; subjecting the circuit to an external field of the kind affecting the flux of emitted internal charged particles, and supplying a bias voltage to the back contact of the specimen. During the power supply to the specimen, at least one of the following is carried out: an electric current through the specimen is measured, and the emitted charged particles are analyzed versus their energy (using a contactless voltmeter) which provides local potential values at chemical entities of the specimen.

Abstract: The invention relates to a photocatalyst containing titanium dioxide, to a method for using it and to its application. A sulphurous titanium dioxide hydrate precipitate is precipitated from an acid titanium oxysulphate solution at a temperature below the boiling point of the solution, e.g. in the range from 70 to 100° C., using crystal nuclei and without addition of base. The precipitate is separated, washed and calcinated. The photocatalytic titanium dioxide thus obtained has a specific area in the range from 100 to 250 m2/g and a 0.3 to 5% sulphur concentration. Catalytic activity has been confirmed in asetal dehyde decomposition and in anionic (SNC?)2 radical formation.
