Provided are: a resin composition for the formation of an optical waveguide, which shows low transmission loss and high heat stability and enables to form a waveguide pattern at high shape accuracy and at low cost; an optical waveguide; a method of forming an optical waveguide; and an optical element using the method. A photosensitive resin composition is used, which includes a polyamic acid represented by a general formula (I) or a polyamic acid ester (A), a compound (B) having an epoxy group, and a compound (C) which generates an acid by being exposed to light.

A passenger detection system for detecting a sitting of a passenger on a seat of a vehicle has a capacitive passenger detection electrode which is embedded in the seat to detect the sitting, a surface unit attached to an upper surface of the seat, a driving unit which applies a voltage between the passenger detection electrode and a vehicle GND, and a detection unit for detecting a capacitance between the passenger detection electrode and the vehicle GND. At least a covering portion of the surface unit is rendered electrically conductive. The passenger detection electrode is covered with the covering portion. Thus, a sitting of the seat can be substantially detected by the passenger detection system.

A rotation angle detecting device includes a columnar permanent magnet that has a generally ring-shaped cross-section and a pair of magnetic poles, a pair of semi-cylindrical yokes disposed in a circumferential direction opposite the permanent magnet, a rotary shaft fixed to the permanent magnet at a shifted rotation axis and a magnetic sensor disposed in one of circumferential gaps between the yokes. The rotation axis and the magnetic poles are arranged so that the magnetic flux density becomes maximum at portions of the yoke less than 90 degrees angled from the circumferential gap in which the magnetic sensor is disposed.

A phenolic resin can be obtained by a condensation reaction between a specific trifunctional aromatic compound and a phenolic compound. This resin can be reacted with a curing agent such as a hexamine to give cured articles having excellent heat resistance, electrical properties, wear resistance and chemical resistance, and the phenolic resin is also much more excellent in curing reactivity as compared with conventional techniques.

An aluminium-based conductive material used in a driving part of robots or various devices and used, for example, in a wiring that is loaded with cyclic bending, as well as an electric wire and a cable using the same, contains 0.1 to 1.0 mass % of scandium and further contains, as a rest part, aluminium and unavoidable impure substances and is formed of a metal texture 10 having crystal grains 11 with an average grain size of 2 μm or less and aluminium-scandium series nanoprecipitates generated in a grain boundary 12 of the crystal grains 11. Further, it is preferable that the metal texture 10 contains the crystal grains 11 of 1 μm or less at a cross sectional ratio of 15% or more.

A tablet compression die configured such that formation of edges on the surface of a tablet is suppressed when the tablet is integrally formed by compression. A tablet compression die is provided with a space (S) into which rods (3, 4) having pressing surfaces (13, 14) at the tips thereof are inserted and which extend in the direction of the axis of the rods (3, 4), and the tablet compression die is used to produce the tablet (11) integrally compacted and formed by compressing powder (12) in the space (S) by means of the pressing surfaces (13, 14). A molding groove (6) having a recessed curved surface is annularly formed on the inner peripheral surface of the space (S). The molding groove (6) is integrally connected to the pressing surfaces (13, 14) and forms a part of the surface of the tablet (11) in forming the tablet. The tablet compression die is also provided with a separating mechanism for separating at least a part of a die body (7) so that the tablet (11) engaged with the annular molding groove (6) can be taken out.
摘要:
An occupant sensing electrode is embedded in a seat. An empty seat capacitance reducing electrode is placed between the occupant sensing electrode and a seat frame of the seat in an opposed relationship to the occupant sensing electrode. A dielectric base film may be interposed between the occupant sensing electrode and the empty seat capacitance reducing electrode. The occupant sensing electrode may include a plurality of electrode portions. The electrode portions may include high potential electrode portions and low potential electrode portions.
摘要:
A strobe device comprising a circuit substrate including a plurality of conductive elastic members. The plurality of conductive elastic members includes a first portion forming a predetermined electric circuitry. A second portion, if present, forms various electrical contacts external to the circuit substrate, e.g., a battery contact. A third portion, if present, elastically retains terminals of electronic elements and functions as an electrical contact. An insulation member having a first surface integrally internalizing the plurality of conductive elastic members in such a manner that the second portion and third portion are exposed. Further, the electronic elements and the optical elements are electrically and/or mechanically coupled to the circuit substrate via the plurality of conductive elastic members and the insulation member. The third portion is provided entirely within the insulation member when elastically retaining terminals of the electronic elements.
