Title: Combined machining device with jet flow and laser beam
Inventor: MORI NAOTAKE
IPC: B23K26/00
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a high-pressure jet flow by surely introducing laser beam into the jet flow while preventing decay by laser beam. SOLUTION: This combined machining device comprises a nozzle head 1 injecting a high-pressure water and a radiation device radiating laser beam, and machines a work by laser beam and high-pressure water jet flow. The device further comprises a nozzle 3 installed on a high-pressure water path outlet side 6b of the nozzle head 1 and having a through-hole 7 communicating with a path outlet side opening. After totally deflecting the radiated laser beam against boundary surface with the path outlet side opening 6b, the nozzle 3 introduces the totally reflected laser beam into the jet flow from the side surface of the through-hole 7. The nozzle 3 is made of sapphire or diamond. The radiation device radiates laser beam from a nozzle outer part to the nozzle 3 through a reflector 15.  An incident angle of the laser beam incident from the nozzle 3 into the jet flow is equal to or more than that on a boundary surface between the nozzle 3 and the air.

Abstract: PURPOSE:To obtain a combined sintered material of Zr oxycarbide and Al2O3 sintered at high temperature under normal pressure by embedding compressed powder of a mixture of ZrC powder having particle diameters in a specific range and Al2O3 powder in Al2O3 powder and sintering. CONSTITUTION:A mixture of (A) 15-50wt.% ZrC powder (particle diameter: 3-10mum) and (B) 85-50wt.% Al2O3 powder is compression molded to give compressed powder, which is embedded in Al2O3 powder. The embedded material is sintered normal pressure at 1,700-1,900 deg.C to give a high-density (93-97% relative density) combined sintered material of zirconium oxycarbide [ZrCxOy (0<x<1, 0<y<1, 0.5<=x+y<=1, 0.05<=y/x<=0.22)] and Al2O3. Addition of <=5wt.% based on Al2O3 of MgO or Y2O3 raises density of sintered material and improves oxidation resistance. The sintered material is useful as cutting tool material, wear-resistant material, heating element material useful in an oxidizing atmosphere and electroconductive material.

Title: Vector product filtering method
Inventor: JIEEMUZU SAAJIENTO RITSUPUSUKO
IPC: G06F3/048
Filed: 1990-09-07
Abstract: PURPOSE: To eliminate the need of smoothing by means of a pre-filter by calculating the vector product of sequential vectors formed between successive indicias in n first consecutive indicias and obtaining a stroke which is provided with second consecutive indicias constituted of m(<n) indicias and which is filtered. CONSTITUTION: The vector product of the vectors constituting the stroke is calculated. When the stroke suddenly curves, sample points are mutually approximated. When the stroke goes straight upward, they are detached. An x-y jitter is considerably removed by a numeral characteristic on the vector product of the vectors constituting the stroke. The vector product of the short stroke is small. The vector product is the sign of the length of one vector x the length of the other vector x an angle between them. When the vector is short, the vector product does not exceed a threshold by any angle. Thus, previous filtering or smoothing becomes unnecessary.

Abstract: PURPOSE:To prevent intrusion of water content in air into an org. crystal of a core and to prevent deterioration of the optical fiber element by forming a buffer layer through which the crystal of the core is not dissolved on the end of an optical fiber element and forming a water-intercepting layer on the surface of the buffer layer. CONSTITUTION:The optical fiber element consists of a core made of an org. crystal and a glass clad 2, and this element produces second-order higher harmonic from the laser light made incident on the core 1. On the end surface of the element consisting of the core 1 and the clad 2, a buffer layer 3 and water- intercepting layer 4 are formed in this order. Further, a protective layer and reflection-reduction film may be formed on the surface of the water-intercepting layer 4 and the protective layer, respectively. The buffer layer 3 is preferably such a film as monomolecule layer of silane coupling agent or silicone compd. in order to improve wettability between an inorg. dielectric and core crystal when the water-intercepting layer 4 consists of inorg. dielectric. The water- intercepting layer 4 needs to be made of a transparent material and an inorg. material having small permeability of water, or an org. water-repellent material containing a fluorine is used for the layer 4.

Title: Impact and vibration absorbing material
Inventor: EDAKAWA HIROSHI
IPC: A63B102/18
Filed: 1990-09-05
Abstract: PURPOSE:To obtain the impact absorbing material which may damp impact and vibration quickly and effectively by fixing the vibration-exciting member with specified weight and height to the object of impact and vibration-source so that minute vibration and rocking are excited by following up the vibration and impact transmitted from vibration source to one end of the member. CONSTITUTION:The impact and vibration generated in an object is transmitted to a vibration-exciting member 2. The vibration exciting member vibrates by following up the transmitted impact and vibration, but minute vibration and rocking are excited by the vibration amount generated by follow-up, while the minute shift of timing is actually generated. Any one of the vibrations shows the action which damps the transmitted vibration from the object 1 of original impact and vibration source, and its vibration energy is absorbed and reduced. Then, the vibration-damping of the body 1 of impact and vibration source is remarkably shortened by the existence of the vibration-exciting member 3.

Title: Hot water feed system using instantaneous water heater
Inventor: AOYAMA KAZUO
IPC: F24H1/18
Filed: 1986-10-04
Abstract: PURPOSE:To make it possible to use a large amount of hot water of an appropriate temperature for a long time by forming a heating circulation system provided with a hot water storage vessel, for guiding hot water within the vessel to the instantaneous water heater by use of a circulation pump for heating, and after heating, returning hot water gain to the vessel. CONSTITUTION:When a power source is turned ON, a circulation pump 4 for heating operates, and water extracted from the bottom part of a hot water storage vessel 1 flows into the instantaneous water heater 5 where ignition and heating of water are carried out to heat water to a predetermined temperature, and hot water thus heated is returned to the upper part of the vessel 1. In this case, when hot water feed faucets 8 are opened, feeing of hot water is carried out at a pressure corresponding to the water feed pressure. When hot water is fed, cool water in an amount equal to that of hot water is supplemented in accordance therewith to the lower part of the hot water storage vessel 1 through a water feed pipe, and feeding of hot water is carried out continuously or intermittently, cool water is replenished, and the interface between a low-temperature zone and a high-temperature zone rises up. Thus, when a temperature adjustor 6 detects a set temperature of 37 deg.C, the circulation pump 6 for heating again operates to carry out heating circulation. In this manner, since water of a predetermined suitable temperature is held at the upper part of the hot storage vessel 1, hot water of a suitable temperature can be taken out at all times.

IPC: G01R31/02
Filed: 1993-09-24
Abstract: PURPOSE:To detect a defect of an internal mutual wiring of a semiconductor integrated circuit in a short time in a nondestructive manner. CONSTITUTION:While a current is supplied to a semiconductor integrated circuit chip 1 from a power source 9, a narrowly reduced laser light is focused on an optional wiring of the chip 1 with the use of a confocal mechanism.
