Abstract:
The position of a metal marker 5 relative to an optical fiber 6 is fixed, and the metal marker 5 can be moved up close to a target site such as a thrombus. It is preferable that the position, in an optical fiber longitudinal direction, of a front-end face of the optical fiber 6 is coincident with the position, in an optical fiber longitudinal direction, of a front-end face of the metal marker 5. More specifically, since the distance between the target site and the front end of the optical fiber 6 is known by radiography, it becomes unnecessary to use a large quantity of contrast agent and irradiate a laser beam depending on skill and intuition, and therefore an effective laser beam irradiation becomes possible.
Abstract:
In order to further improve driving stability, a dumper 10 mounted in a vehicle 14 in which a drive unit 11 having an engine 11a and a drive shaft 12 having tires 13 connected to respective end portions in the axial direction thereof, to which drive shaft torque is transferred from the engine 11a, are provided in a vehicle body frame 2, comprises: a connection part 16 for connecting the drive unit 11 with the vehicle body frame; a detection means 17 for detecting variation of torque transferred from the drive unit 11 to the drive shaft 12; and a controller 18 for controlling at least roll vibration of vibration behaviors of the drive unit 11 by operating the connection part 16 on the basis of a detection signal from the detection means 17.
Abstract:
A camera head (2) of a head separated camera (1) includes an adjustment value storage unit (9) that stores black balance adjustment values OBR, OBG and OBB for three image pickup devices (5) and a black balance adjusting circuit (8) that adjusts the black balance based on the black balance adjustment values OBR, OBG and OBB so as to make the black levels of the video signals approximately equal to each other. The video signals adjusted in black balance by the black balance adjusting circuit (8) are transmitted from the camera head (2) to a camera control unit (3). Thus, there is provided a head separated camera that does not have to readjust the black balance even if the combination of the camera head, a camera cable and the camera control unit is changed.
Abstract:
A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid, and (B) an acid generator. The resin (A) is a polymer comprising tertiary alkyl protective group units having a hydrophobic tetracyclo[4.4.0.12,5.17,10]-dodecane structure, hydroxyadamantane units, monocyclic lactone units, and carboxylic acid units. The acid generator (B) is a specific sulfonium salt compound.
Abstract:
A pattern is formed by applying a first positive resist composition comprising a polymer comprising recurring units which become alkali soluble under the action of acid onto a substrate to form a first resist coating, heat treating, exposing, heat treating, developing to form a first resist pattern, applying a pattern surface coating composition comprising a hydroxyl-containing crosslinkable polymer onto the first resist pattern and crosslinking, thereby covering the first resist pattern with a crosslinked polymer film, applying a second positive resist composition thereon, heat treating, exposing, heat treating, and developing to form a second resist pattern.

The resin (A) is a polymer comprising tertiary alkyl protective group units having a hydrophobic tetracyclo[4.4.0.12,5.17,10]dodecane structure, di- or trihydroxyadamantyl units, and monocyclic lactone units.
Abstract:
A detecting unit 210 detects a physical quantity generated from a revolving tire for each tire. An adaptive digital filter 222 extracts a specific signal for each tire from signals corresponding to the physical quantity detected by the detecting unit 210. A judging unit 230 judges that the tire is abnormal when a difference value between two signals extracted by the digital filter 222 exceeds a predetermined threshold.
Abstract:
There is provided an apparatus for measuring forces acted upon a tire in which a radial force and a peripheral force acting to the tire, which are required for the high precision measurement of a friction coefficient on a road surface, are simply measured in a high precision by detecting a magnetic field formed by a magnet fixed to a tread portion of the tire by a magnetic sensor fixed to a rim and measuring the forces acting to the tire from a variant pattern of a magnetic flux density detected un the rotation of the tire and without influencing upon the balance of the tire, which contributes to the high precision measurement of the friction coefficient on the road surface.
Abstract:
Photoacid generators have formula (1) wherein R1 and R2 are alkyl, or R1 and R2, taken together, may form a C4–C6 ring structure with sulfur, R is hydrogen or alkyl, R′ is hydrogen, alkyl, alkoxyl or nitro, n is 1 to 6, and Y− is alkylsulfonate, arylsulfonate, bisalkylsulfonylimide or trisalkylsulfonylmethide. Chemically amplified resist compositions comprising the same have improved resolution, thermal stability, storage stability and minimized line edge roughness
Abstract:
Sulfonate salts have the formula:CF3—CH(OCOR)—CF2SO3−M+ wherein R is C1-C20 alkyl or C6-C14 aryl, and M+ is a lithium, sodium, potassium, ammonium or tetramethylammonium ion. Onium salts, oximesulfonates and sulfonyloxyimides and other compounds derived from these sulfonate salts are effective photoacid generators in chemically amplified resist compositions.
