Title: Enciphered data resending system
Inventor: KAMISAKA NAOYUKI
IPC: H04L9/14
Filed: 1987-03-04
Abstract: PURPOSE:To prevent the validity of encipherment from being diminished by resending, by using the same key as the one by which a transmission data that is the origin of a resending request is enciphered as the key to encipher a resending data. CONSTITUTION:In a case where a data having the same content as that of an encipher text transmitted once is enciphered again and resent, the same key used previously is used as the one for the encipherment. Since the encipher text to be resent is the same text sent previously, a wiretapper can obtain nothing other than a bit of information that the encipher text is a resent text by tapping. In other words, 1 is obtained by dividing the encipher text tapped first by the encipher text resent at a second time. In such a way, at the time of resending the same data again when no data sent once is received at a receiver adequately, the key used previously is used, therefore, another key cannot be recognized easily by the wiretapper.

After the pressure of gas such as CO2 is adjusted to a value within the range from no less than the pressure of molten resin at a pouring part to less than and equal to 100kg/cm<2> through a pressure reducing valve 3, the gas is poured from a cylinder inlet corresponding to a bent part through a mass flow controller 4, which actuates at high temperature, in an extruder at the predetermined flow rate such as 1l/min. If the pressure of the gas is below the pressure of resin melt, the gas can not be forced in to the resin. Further, if the pressure of the gas exceeds 100kg/cm<2>, it exceeds the breakdown strength limit of the mass flow controller. As the thermoplastic resin, olefin polymer such as butene polymer or the like, copolymer of different alpha-olefin, copolymer of olefin polymer and vinylmonomer such as vinyl chloride or the like, fluoroplastic such as polyvinyl chloride or the like, polyamide such as nylon 66 and the like are mentioned.

IPC: H01L27/04
Filed: 1986-03-05
Abstract: PURPOSE:To raise the withstand voltage against static breakdown while restraining the pattern space of a resistor and a protective diode comprising an input protective circuit from expanding by a method wherein inductor interconnection layers are connected to a gate electrode of an insulated-gate field- effect transistor formed in an inner circuit region of a semiconductor substrate. CONSTITUTION:When a bonding pad 16 is instantaneously leaded with any overvoltage and overcurrent, a surge current flows through a polycrystalline silicon interconnection layer 14, however, this layer 14 can be directly connected to a diffused interconnection layer 13 so that the charge on the film 14 within the limit of withstand surge current may be relieved by the diffused interconnection layer 13 to be further relieved by a substrate 11 due to the function of a protective diode. In other words, the surge current restricted by a protective resistor composed of the polycrystalline silicon interconnection layer 14 and the diffused interconnection layer 13 is absorbed into the substrate 11 by the function of protective diode resultantly raising the withstand surge voltage.

Abstract: A vertical column (1), assembled from one or more tubular parts (2), is charged with the liquid to be treated by gases and also with the gases under pressure. Each tubular part (2) of the column (1) contains a hollow spherical funnel (3, 3') which has an electrically conducting surface and an enlarged, rough head area.

It is positioned approximately tangentially and in a transverse direction relative to the longitudinal axis of the spherical funnel (3, 3'). Its orientation confers the desired flow direction on the liquid entering the sphere (3a). The liquid is split electrolytically-physically or only physically in column (1) and then set in centripetal whirling motion. In this way the liquid is saturated in column (1) with gases to a very high degree, and such saturation to a very high degree persists for several hours. <IMAGE>

Abstract: PURPOSE:To provide a cooling device of improved uniform cooling and cooling capacity for hot-rolled steel sheets by providing plural slit nozzle for supplying cooling water provided with angles so as to spread in the width direction of the steel sheet with respect to the advancing direction of the steel sheet after hot rolling. CONSTITUTION:While a steel sheet 3 after hot rolling is traveling in an advancing direction 4 at a predetermined cooling speed, cooling water is dropped in the form  of film from slit nozzles 10 onto the steel sheet 3, so that the steel sheet 3 is cooled.  In this case, the cooling waer 12 is first flowed in the width direction of the steel  sheet 3 at the front face of the cooling water film 11 falling from the nozzles 10 onto  the steel sheet 3 under traveling, thence it is flowed between the water films 11  along the advancing direction 4 of the steel sheet 3 so as to prevent the thickness of the water films from increasing. Hence, disturbing of the collision of the water films  11 dropping in succession onto the steel sheet 3 against the steel sheet 3 does not  occur and the decrease in the cooling capacity for the steel sheet 3 is prevented. It is  necessary to set the above-described nozzles 10 at angles of 45-90 deg. with respect to  the advancing direction of the steel sheet 3.
