Abstract: A sterilization device (1) includes a peroxynitric acid gas generation section (10) and a sterilization treatment section (20). The peroxynitric acid gas generation section (10) generates peroxynitric acid gas obtained by gasifying a peroxynitric acid-containing liquid. In so doing, for example, the peroxynitric acid gas generation section (10) generates a peroxynitric acid mist by ultrasonically atomizing the peroxynitric acid-containing and causes the liquid, peroxynitric acid gas to be generated from the peroxynitric acid mist. The sterilization treatment section (20) applies the peroxynitric acid gas to a sterilization target (22) to sterilize the sterilization target (22).

Abstract: A sterilization method is provided which acquires microbicidal activity equivalent to plasma-treated solution or more powerful than the same without the use of a plasma generation device. The sterilization method includes applying liquid containing peroxynitric acid (HOONO2) produced by chemical reaction to an object to be sterilized under acidic conditions of a pH value of 4.8 or lower. The liquid containing the peroxynitric acid is produced by mixing nitrous acid and peroxide together, for example, mixing nitrite and peroxide together.

Abstract: An apparatus includes a pipe line, water supplying devices, gas supplying devices, a plasma generation device, a cooling device for cooling water flowing in the pipe line, and a vessel. The plasma generation device has a high-voltage electrode and a ground electrode which are provided outside the pipe line to face each other with the pipe line interposed therebetween and applies a plasma treatment continuously to the water flowing in the pipe line by generating dielectric barrier discharge between the high-voltage electrode and the ground electrode. The cooling device cools the water to have a low temperature of 10° C. or lower. The plasma treatment is applied to generate a plasma-treated solution in which superoxide anion radicals (O2?.) or a precursor thereof is diffused in the water and a microbicidal activity is sustained.

Abstract: A sterilization treatment method includes producing a plasma-treated solution in which biocidal activity is held by diffusing, in a liquid, superoxide anion radicals (O2?.) or a precursor of the superoxide anion radicals (O2?.) by plasma generated in a vicinity of or in a manner to make contact with the liquid; freezing the plasma-treated solution to produce solid ice and store the solid ice in a frozen state; thawing the solid ice to the plasma-treated solution in which biocidal activity by the superoxide anion radicals (O2?.) or the precursor of the superoxide anion radicals (O2?.) is held; and applying a sterilization treatment by any one of the following: allowing the plasma-treated solution to have a pH value of 4.8 or lower to apply the resultant plasma-treated solution to an object, and applying the plasma-treated solution to an object of which a pH value is 4.8 or lower.

Abstract: An object of the present invention is to efficiently sterilize microorganisms present in or on a surface of a liquid. Plasma is generated in a vicinity of or in a manner to make contact with a liquid whose pH value is adjusted to become 4.8 or lower, more preferably 4.5 or lower. The plasma is generated in an atmospheric gas containing nitrogen, e.g., in the air. Superoxide anion radicals (O2?.) that are generated by the plasma react with protons (H+) in the liquid to form hydroperoxy radicals (HOO.). Further, nitrogen and oxygen included in the air are combined together by the action of plasma to form nitrogen oxide such as nitric oxide (NO.). The nitric oxide (NO.) combines with the hydroperoxy radicals (HOO.) to become peroxynitrite (ONOOH(ONOO?)) having a high microbiocidal activity.

Abstract: A dental clinical apparatus having a function which conventional instruments for dental treatment have not had and having a novel constitution. The dental clinical apparatus includes a syringe which has a fluid jetting system for dental treatment and a plasma jet applying means for producing a plasma jet from the end by allowing a low-frequency high-voltage power supply to apply a low-frequency high voltage between electrodes on the outer peripheral surface of a rare gas tube through which a rare gas having a low dielectric breakdown voltage under the atmospheric pressure is flowed, and thereby causing electrical discharge.

Abstract: In synchronization of a conventional AV system, when a stream as the master stops, a system clock cannot be corrected for synchronization. Since the correction is consistently performed even when an error is small, overhead of correction is large. On the other hand, when an error is large, sharp correction causes a feeling that something wrong. In the present invention, when the stream as the master stops, previously registering the degree of priority regarding the master, consideration of a corrected period or a previous error for the system clock, or transmitting a stream containing information regarding the master can allow for other process to serves as the master. Accordingly, it is possible to provide a method for synchronization with maintaining correction of the system clock. When a corrected error is large, gradual correction or reference can provide a system with normal feeling.

Abstract: The data sharing apparatus in the present invention includes a first processor and a second processor, each of a different endianness, that are both connected to the memory via the data bus, in a byte order based on the endianness of the first processor. It also includes an address conversion unit which converts at least one lower bit of an address to indicate a reversed position of data in the data bus, and outputs the converted address to the memory, in the case where the second processor performs a memory access on the shared memory for data with a smaller width than the data bus.
