Inventor: KITAO KOICHI
IPC: C08L23/12
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To improve resistance to impact by retaining a molded body formed by melt molding polypropylene resin of specified isotacticity rate and then water cooling the resin in a specified temperature range for a given time. SOLUTION: A molded body formed by melt molding polyprepylene resin of isotacticity rate of 95% or more and then water cooling the resin is retained in a temperature range of 120 deg.C or higher to the melting point or lower for a given time. When the isotacticity rate is less than 95%, the increase of impact absorbing energy is not larger compared with the processes heretofore available. When the retaining temperature is lower than 120 deg.C, the increase of impact absorbing energy is not larger either compared with the processes heretofore available. In that case, it is not necessary to retain the molded body at the given temperature, but the temperature gradient can be generated in the temperature range. As the time of retaining heat treatment is vaired by the thickness and shape of the molded body, the optimum time is determined each time.

Title: Impact buffer
Inventor: UOMORI KENYA
IPC: B65D81/133
Filed: 1987-10-07
Abstract: PURPOSE:To obtain a impact buffer without deterioration with time and capable of easily loading and unloading a load, by placing a load receiving container made of superconductor in a magnetic field generated by a magnetic field generator. CONSTITUTION:A load is placed in a superconducting load receiving container 9, which is then placed in a body 10 and a lid 8 is closed. When current is passed to a electromagnet using a superconducting coil, in the impact buffer where electromagnets are disposed at intervals, magnetic fields of which flux density increase toward inner wall surfaces are generated around the container 9. A magnetic flux does not leak to outside due to magnetism shield outer frame 7. This cause the superconducting container to letivate at the center of the impact buffer because of Meissner effect to prevent external impact from directly hitting the container, decrease acceleration by impact and give an impact buffering effect.

Title: Liquid discharge head and manufacture thereof
Inventor: SATO KANKI
IPC: B41J2/16
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To enable the refill of ink at high frequency by reducing the resistance of an ink passage and to improve recording quality at a high recording speed by making the passage near a liquid supply port higher than the passage near a discharge energy generating means. SOLUTION: The passage height h2 of the upper surface (c) of a substrate 1 near a heat generating resistance 2 is made greater than the passage height h1 of the upper surface (a) of the substrate 1 near a liquid supply port 3. In other words, the upper surface (c) is dug to be deeper than the upper surface (a) by (h2 -h1 ), and the upper surfaces (a), (c) are formed with an inclined surface between them. In a liquid discharge head, since the passage height from the supply port 3 to the resistance 2 is higher as compared with a conventional head, liquid can be refilled smoothly and promptly into a foaming chamber 7 including the resistance 2. In this way, the frequency of refill can be increased to be able to respond sufficiently to high speed recording of a high driving force frequency.
