Inventor: SHIBUKAWA MASAHIKO
IPC: D06M11/00
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To solve problems that although metallic substances are widely used as electroconductive substances, these metallic electroconductive substances have a potential of inhibiting the formation of a resource/environment-circulation type society and also causing a direct harm to our life, and while, although the developments of non-metallic electroconductive substances such as an electroconductive plastic material are being performed, they are expensive and have scarce possibilities of wide uses. SOLUTION: This plant-based electroconductive fiber is characterized by coating carbon-based fine particles by a high pressure on a plant-based fibrous material. The fiber has characteristics such as biodegradability, gentleness to the human body, a low cost, etc.

Filed: 2001-11-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lens holding mechanism for a camera which uses a solid-state image pickup element that generates no defocusing caused by environment change such as temperature fluctuation and vibration.  <P>SOLUTION: A longitudinal knurl 3, parallel to optical axis, is formed on the outer peripheral surface of a lens frame 10. A rotation blocking part is provided on the outer peripheral surface of a lens connection cylinder. A lens retainer 2 is provided with a knurl engagement groove whose form is complementary with the knurl part and a rotation block engagement part whose form is complementary with the rotation blocking part. By allowing the rotation blocking part to engage with the rotation block engagement part, the lens retainer 2 engages with the lens connection cylinder while blocking rotation of the lens retainer. After the lens is focused, the lens retainer is shifted in the optical axis direction so that the knurl engagement groove engages with the knurl part, and the tip of a screw screwed in the lens retainer presses the outer peripheral surface of the lens connection cylinder for fixing the lens.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem of a conventional miniature microphone being built in a portable apparatus that since a resilient connector of anisotropic conductivity or a connector inserted with a spring terminal is required, the number of components and the labor required for assembling work increases to have an adverse effect on the reliability of electrical connection, and to realize a microphone which can be built in an apparatus without requiring any connector.  <P>SOLUTION: A spring terminal 23 is fixed to the lower surface of a circuit board 22 at the bottom of a microphone 21 covered with a case 1 on the outside thereof. The spring terminal is a leaf spring of a metallic resilient body being set and directed in a groove 22a made in the lower surface of the circuit board. It is secured in place by pushing a protrusion 23a into a through hole 22b of the circuit board and electrical connection is established by a contact pressure against a conductive coating on the inner surface of the through hole. When the microphone is built in while being superposed on the circuit board, forward end of the spring terminal abuts against a connection electrode on the circuit board to be connected electrically therewith.
