Title: External plate of hull
Inventor: OOTA SHIYOUZOU
IPC: B63B59/04
Filed: 1980-08-28
Abstract: PURPOSE:To certainly prevent adhesion of ocean living things on the external plates of a hull for a long period by simple maintenance, preventing generation of public nuisance by applying mirror-shaped lining formed of plastics onto the part of the external plates of the hull in contact with seawater. CONSTITUTION:Mirror-shaped lining 1 formed of plastics is applied onto the part of external plate 3 of a hull contact with seawater 4. For example, the external plate of the hull is sand-blasted, and lining is applied through powder sintering, and surface is mirror-finished. In this case, polyamide resin and the like are used as plastics, and especially use of nonpolar polyethylene and the like is effective. Thus, adhesion of ocean living things on the external plate of the hull can be prevented simply and certainly, and the increase of resistance in water during navigation of a ship due to adhesion of ocean living things can be reduced. Further, superior preventing effect can be maintained for a long time by simple maintenance without generating public nuisance.

Title: Method for driving high-polymer liquid crystal and liquid crystal shutter
Inventor: NAGASE YUTAKA
IPC: C08F30/08
Filed: 1995-05-17
Abstract: PURPOSE: To facilitate the control to change over a transparent state and an opaque state by heating high-polymer liquid crystals, then allowing the liquid crystals to cool, heating the high-polymer liquid crystals, allowing the liquid crystals to cool under impression of an electric field thereon, releasing the impressed electric field and maintaining the light transparent state. CONSTITUTION: The high-polymer liquid crystals 302 are held between a pair of substrates 300 and 304 arranged in such a manner that transparent electrodes 301, 303 face each other. After the high-polymer liquid crystals 302 are heated near to the transparent temp., the liquid crystals are allowed to cool, by which an opaque light scattering state is formed and the high-polymer liquid crystals 302 are heated near to the transparent temp. The high-polymer liquid crystals are allowed to cool under the impression of the electric field thereon, by which the transparent light transparent state is maintained and thereafter, the impressed electric field is released to maintain the light transparent state.  The transparent temp. in such a case refers to the temp. at which the liquid crystals shift from the liquid crystal state (liquid crystal phase) to the isotropic liquid crystal state (isotropic phase). As a result, the electric power consumption is needed at the time of switching between the transparent state and the opaque state. There is no more need for the consumption of the electric power in holding of the respective states occupying most of the time as an optical shutter.

Title: Focus ion beam device
Inventor: SAWARAGI HIROSHI
IPC: H01J37/12
Filed: 1986-05-21
Abstract: PURPOSE:To make it possible to keep the dosage constant without converting the probe diameter, by converting the electrodes of a pentamerous lens according to the variation of the acceleration voltage. CONSTITUTION:This object lens 9 is composed of five pieces of Einzel lenses, electrodes 1 and 5 are grounding electrodes, and a fixed voltage 50KV is applied to an electrode 4 to keep the potential difference between the electrodes 4 and 5 at 50 KV constantly. A voltage Vi is applied to an electrode 3, while a voltage Vi/2 is applied to an electrode 2. The voltage Vi is variable and set that Vi = 100 KV when the acceleration voltage V = 200 KV, and Vi = 0 V when the acceleration voltage V = 100 KV. In other words, when V = 100 KV, the electrodes 1, 2, 3, and 5 are grounded, and the electrode 4 is at 50 KV. Therefore, that is the same as a triple lens composed of electrodes 3,4, and 5, and since the main face position of the lens is close to the focus point, the color aberration coefficient is smaller than that of a pentamerous Einzel lens at V = 200 KV condition, and the dosage is not vairated.
