Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device having the optical scanning property with high resolving power and plural modes for providing optical scanning at extremely high speed at the time of requiring not so much high resolution. SOLUTION: The natural frequency of a small magnet 3 is changed twice as much by changing the temp. of a tortion spring 5 made of shape memory alloy to lower temp. and higher temp. than the inverse transformation temp. Af point by a heater 6. Consequently, an optical scanning device provided with a high resolving power and a half resolving power but having a high speed mode with a main scanning time twice as much is realized while the fundamental clock of optical modulation of a light source 12 is made to be the same as it is.

Title: Method for stabilizing material for immunosassay
Inventor: HAGI NORIO
IPC: G01N33/543
Filed: 1988-12-15
Abstract: PURPOSE:To decrease the deactivation of antibodies and to allow the long-term preservation of the antibodies by cleaning a carrier combined with the antibodies with a cleaning liquid contg. a stabilizer. CONSTITUTION:The carrier combined with, for example, polyclonal antibodies, monoclonal antibodies, etc., is cleaned with the cleaning liquid contg. the stabi lizer and is then freeze-dried. The cleaning in this case merely involves immers ing of the carrier into the cleaning liquid and separating the liquid and the carrier and, therefore, the smaller amt. of the stabilizer to be used is necessitat ed. The freeze drying is executed by freezing the material for 2 to 24 hours in an incubator kept at, for example, -80 to -20 deg.C in an ordinary manner, then drying the material for 3 to 16 hours at -20 to 0 deg.C under 0.01 to 0.2Torr reduced pressure and further, drying the material for 2 to 4 hours at room temp. monosaccharides, such as glucose and fructose, disaccharides, such as cane sugar and lactic sugar, or dextran, polyvinyl pyrrolidone, etc., are used as the stabilizer. A physiological salt soln., a buffer soln. having pH to avert the denaturation of the combined antibodies, etc., are used.

Abstract: PURPOSE:To perform both contact developing and non-contact developing with a simple constitution by providing a magnet attached to a developer carrier so that the magnet can perform a contact developing action and a non-contact developing action switchably and selectively. CONSTITUTION:The magnet 502 is provided so that it can be switchably and selectively changed over between the moving condition where a magnet field is formed so that developer held on the developer carrier 501 is brought into in contact with an electrostatic latent image side in a developing area, and the stopping condition where the magnet field is formed so that the developer on the developer carrier 501 is not in contact with the electrostatic latent image side in the developing area. Thus, depending on which component of the high spatial frequency component or the low spatial frequency component is contained more in the electrostatic latent image formed on a latent image carrier 1, the developer on the developer carrier 501 comes into contact with or not in contact with the electrostatic latent image. As a result, developing operation complying with each image condition can be performed. Therefore, both contact developing and non-contact developing can be performed by a simple constitution.

Abstract: PURPOSE:To increase the resistance value after quenching and improve the cooling efficiency, in a current-limiting element manufactured by using ceramic superconductor, by calcinating a wire so as to form a nonconductive type after melting the sheath of the wire which has been temporarily sintered by using the sheath such as of silver. CONSTITUTION:A current limiting element is formed by binding a wire by melting and sintering the wire after temporarily sintering and compacting the wire by using a copper or silver sheath. A ceramic superconductor is once temporarily sintered to compound a superconductor 1, which is molded and further sintered. After temporarily sintering and molding the wire in a copper or silver sheath, the sheath is melted by nitric acid or the like to produce a bare wire, which is sintered to produce a long element without sheath. Next, the wire is binded to get a required sectional area and fixed on an insulating plate 2 in nonconductive winding. Thereby, the long current limiting element can be obtained, the cooling efficiency is excellent because of the large sectional area of the wire contacting liquid nitrogen, the quick transfer to superconducting from normal conducting after recovering short-circuit fault becomes possible, and the circuit can be reclosed at high speed.

Title: Switching member with protective function and control circuit unit employing it
Inventor: MIZUNO FUMIAKI
IPC: H01L27/04
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To mount a PTC compactly on a board while protecting a switching device against overcurrent and undue temperature rise by stacking the PTC while touching the surface arranged with the conduction terminal of a semiconductor switching device directly. SOLUTION: A PTC 12 and an FET 14 are mounted on a circuit board 10 while being stacked. When the FET 14 is heated and the temperature is increased to an undue level, heat is transmitted directly to the PTC 12 touching the FET 14 to cause temperature rise of the PTC 12. Consequently, the electric resistance thereof increases and the current decreases correspondingly thus preventing the undue temperature rise state from being sustained. According to the constitution, current decreases quickly at the time of emergency, i.e., undue temperature rise or overcurrent, and the switching device is protected against failure or breakdown. Furthermore, required area is reduced and the overall size of unit is reduced as compared with a unit where the devices are mounted individually on a board.
