Filed: 1990-08-15
Abstract: PURPOSE:To protect a TAB lead from an outside stress and to realize effectiveness of defective analysis by fixing and supporting a cooling mechanism to a package main body and by connecting the TAB lead to a surface side of a semiconductor circuit device. CONSTITUTION:A cooling part 6 is inserted to an opening 10 formed at a center of a package main body 4. The opening 10 is a bottomed hole. After a semiconductor circuit device 1 is inserted to the bottom part, the cooling part 6 is overlaid from an upper part thereof.

Title: Base isolation elements
Inventor: AKIMOTO MASAO
IPC: F16F15/02
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To dispense with a special damping device and reduce the size by engaging a plurality of wheels between recessed lower rail and upper rail fixed in a plurality of parallel lines, and rolling each wheel along the upper and lower rails while independently rotating by earthquake motion. SOLUTION: Lower rails 4 are fixed on a support body 2 in a plurality of parallel lines, and formed into a recessed form having the lowest level in the center part. Upper rails 5 are fixed under a body to be supported 3 in parallel to the lines of the lower rails 4, and formed into a recessed form having the highest level in the center part. A plurality of wheels 7 arranged on a pair of axles 8 is engaged between the lower rails 4 and the upper rails 5. When an earthquake motion is generated in the lateral direction X, the wheels 7 are rolled on the lower rails 4 and the upper rails 5 with rotation, and relatively displaced. Consequently, since the load of the body to be supported 3 acts through the wheels 7 and the axles 8 without directly reaching the support 2, the friction between the wheels 7 and the axles 8 acts as a damping force to work a base isolating effect.

Title: Light-absorption-spectrum measuring apparatus making use of slab optical waveguide
Inventor: KATO KENJI
IPC: G01N21/27
Filed: 1994-09-09
Abstract: PURPOSE: To provide a light absorption spectrum measuring apparatus by which the extremely large number of reflections is obtained and by which a light absorption spectrum can be measured with high sensitivity by a method wherein condensed light is introduced into an optical waveguide layer and light which has been reflected totally inside the layer is taken out. CONSTITUTION: Radiated light from a light source 10 is condensed 11 so as to be incident on an incidence side prism 12, and light in a wavelength range is introduced at once into an optical-waveguide layer 52 in a slab optical waveguide 13. The introduced light is totally reflected extremely many times inside the layer 52, and evanescent light is generated very close to the surface of the layer 52. When the incident light inside the layer 52 is passed just under a sample 54, the generated evanescent light is absorbed by the sample 54, the incident light is weakened, and the intensity of incident light from the layer 52 is reduced. The light whose total reflection has been repeated inside the layer 52 is taken out at once by a radiant light side lens 15, and it is separated 41 into its spectral components so as to be sent to a detector.  Consequently, the light is introduced into the layer 52 from both sides, i.e., the side of the sample 54 and the side of a reference part 53 in which the sample does not exist, its total reflection is repeated, and the intensity of the radiated light is measured. When a measured result is compared and analyzed 42, the light-absorption spectrum of the sample can be measured with high sensitivity.

Abstract: PURPOSE:To enhance the durability of a liquid-filled anti-vibration device, by allowing no stress to act to the wall of a fluid chamber made of a thin elastic rubber material, when a vehicle engine or the like is supported by the device. CONSTITUTION:A thin elastic rubber wall 2 is pushed in by a thrusting jig 10 which has a slightly less diameter than a second fluid chamber B and whose tip has a spherical face, so that the dome-shaped wall 2 has its central part curved downwards and is formed as waves so the volume of the second fluid chamber is decreased. A first fluid chamber A is then closed by a cover plate 8. Even when an engine is supported, no tensile stress acts to the thin elastic rubber wall 2 so that the durability and liquid tightness are enhanced.
