IPC: B28B1/00
Filed: 1993-04-30
Abstract: PURPOSE:To perform easy and inexpensive manufacturing of a reversal mold and a ceramic product in a complicated form, by a method wherein ceramic slurry is cast into a hollow part of the reversal mold to a master block and after a core is manufactured by solidifying and allowing the same to gel, the core is taken out and fired. CONSTITUTION:To manufacture a ceramic product, a model having a form which is desirous to manufacture, that is, a master block 1 and pedestal 2 are made of a metal. Then the model having a reversed form to the master block 1 and a reversal mold 3 are manufactured of a material which has plasticity or material solubility and does not have water absorption properties. The ceramic slurry is cast into a hollow part of the reversal mold 3, that is, a part having a form of the master block. Then only the ceramic slurry is heated, solidified or allowed to gel and the core is manufactured. On the one hand, the reversal mold 3 on the circumference of the core is plasticized or dissolved and the core is taken out. The core is fired and a ceramic product is completed after that. Hereby, manufacturing of the reversal mold 3 and the ceramic product having a complicated form is performed simply and inexpensively.

Abstract: PURPOSE:To prevent the stress concentration to connecting nuts, mouth opening, etc., by providing the peripheries in the apertures of spike insertion holes with reinforcing bodies 1 formed of a blank material having the higher rigidity than the rigidity of shoe sole bodies. CONSTITUTION:The shoe sole bodies 4a are installed in metallic molds and the reinforcing bodies 1 subjected to a primer adhesion treatment are placed in the apertures of the spike insertion holes.

Title: Bloodless continuous sphygmomanometer
Inventor: NISHIMURA YUJI
IPC: A61B5/022
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a bloodless continuous sphygmomanometer which allows properly setting the time to perform calibrations. SOLUTION: Vibration is induced on an artery in a living body from the surface of the body by use of an exciter 1, and the propagation wave of the vibration induced is detected by a detector 2. Changes in phase of the propagation wave are calculated by use of an MPU 6. A cuff control unit 8 activates a cuff 7 and determines the highest, lowest, and average blood pressure values in one heartbeat and the MPU 6 performs calibrations using these values. The propagation wave detected by the detector 2 while the cuff 7 is compressing a part of the living body is analyzed and the MPU 6 determines the wearing position of a calibration cuff. When the condition of the artery with vibration induced therein is affected by compression provided by the cuff 7, calibrations are not performed before the artery returns to its original state. Therefore, accurate calibrations are made possible.

Title: Glass board for recording medium, recording medium using glass board and manufacture of glass board for recording medium
Inventor: OMORI TAKAO
IPC: G11B7/26
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To give a mechanical strength sufficiently durable against a strong centrifugal force of a high speed rotation by chemically strengthening a glass board by ion exchanging the board at a temperature of a distortion spot or less, and forming a compression stress layer having a specific compression stress and a specific thickness on a surface of the board. SOLUTION: The glass board is chemically strengthened by ion exchanging at a temperature of a distortion spot or less. In this case, a compression stress for forming a compression stress layer on a surface of the board is decided to 300 MPa or more, a ratio of a thickness of the layer to that of the board is decided to 0.10 to 0.25, and a maximum value of a tensile stress in the board is decided to 50 to 300 MPa. Thus, a stress relaxation of a surface stress layer by ion exchanging is small, and the board can be effectively chemically strengthened without generating a warp or a deformation. The chemical strengthening by the ion exchanging is conducted by dipping the board in a molten salt and replacing ions in the glass with ions having larger ion radius, thereby forming a compression layer on a surface.

Title: Method and equipment for manufacturing integrated circuit by laser direct write
Inventor: ARUBAATO EMU REUNGU
IPC: B23K26/08
Filed: 1991-03-15
Abstract: PURPOSE: To make personalized custom or semi-customer integrated circuits ICs with a very fast turnaround time by reducing scanning errors by just the magnification factor of a beam expander, while allowing a scanning laser beam to pass through the beam expander. CONSTITUTION: A laser beam source 10 emits a helium-cadmium laser 11. The beam 11 is made to blink by an AO modulator 12. A modulated leaser beam 13 is deflected by a rotating polygon mirror 14 having eight faces. A magnification, which is the ratio of the diameter of an emerging beam to that of an incident beam, is fe/fi, and mechanical scanning errors are reduced by this ratio. A scanning laser 24 at the exit of a beam expander 17 is focused via an objective lens of a microscope. As a result, scanning lines are generated on a surface of an IC wafer 4. Laser beam-based scanning of a direct write system provides very high resolution and accuracy. Hence, personalized customer or semi-customer integrated circuit ICs can be supplied with a very fast turnaround time.
