Title: Mercapto-group-containing polymer
Inventor: JOSA JUNICHI
IPC: C08F8/34
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a mercapto-group-containing polymer soluble in a variety of solvents. SOLUTION: This mercapto-group-containing polymer is obtained by substituting the chloride groups of a polymer (A), which has a polyethylene skeleton wherein the chloride groups are directly substituted, such as a polymer made of monomers including vinyl chloride, by mercapto groups. In this mercapto- group-containing polymer, the ratio of the mercapto groups to the unreacted remaining chloride groups is 1.5 or more and the ratio of the sulfide bond containing groups is 7 or less. The mercapto-group-containing polymer can be easily obtained by reaction of the polymer (A) with a hydrosulfide of an alkali metal.

Title: Electron microscope
Inventor: ITO TAKASHI
IPC: H01J37/04
Filed: 1991-08-30
Abstract: PURPOSE:To provide an electron microscope which is optimum to observation of a transmitted electron-beam image. CONSTITUTION:The current of the electron beam passed through a sample 3 and radiated onto a fluorescent panel 15 is detected by a current detector 16. A control circuit 17 sends, in response to a current signal sent from the current detector 16, a brightness signal corresponding to the current in the current signal to a control circuit 18. The control circuit 18 controls the gain of a TV camera 8 to, for example, a gain A in response to this brightness signal. In response to a drive signal from a CPU 10, a fluorescent plate drive mechanism 11 operates to open a fluorescent plate 7. The TV camera 8 takes photograph of a transmitted electron-beam image of the sample 3. The control circuit 18 which has received a control signal from CPU 10 controls the gain of the TV camera 8 to, for example, a gain B in accordance with the brightness of an image signal sent from the TV cameral 8. The gain of the TV camera 8 is instantaneously changed from the gain F to the gain B. Therefore, a clear sample 3 transmission electron beam image is displayed on the picture screen of a cathode-ray tube from a time at which the fluorescent panel 15 is opened.

IPC: H02P23/07
Filed: 1986-10-17
Abstract: PURPOSE:To obtain stable slip output signal, by suppressing the harmonic component of slip detector output induced when negative-phase-sequence voltage component is put together with slip detector input voltage. CONSTITUTION:When negative-phase-sequence voltage component is put together with the primary voltage of a detected rotary machine 1 because of a power system asymmetrical-accident and the like, then the output voltage of a demodulator 5 is set to be {(2-s)f0} component added to slip frequency (sf0) component. By applying the voltage to a smoothing circuit 6, the (2-s)f0 component is suppressed, and the output of the slip frequency sf0 component is generated. When the rotating speed of a slip detecting rotary-machine 2 is changed, the frequency of the (2-s)f0 to be suppressed is also changed. However, the changes are permitted to correspond with each other, by providing the input of rotary frequency detected by a speed detecting section 7, to the smoothing circuit 6, and by changing the frequency characteristic of the smoothing circuit 6 according to the value of the rotary frequency.

Title: Optical communication line
Inventor: HAJIKANO KIYOSHI
IPC: G02B6/38
Filed: 1985-11-05
Abstract: PURPOSE:To obtain a solid parts which are connected to an optical communication line and a connector by laminating and sticking minute metallic pieces due to spark on the rear end part of a ferrule and the outside peripheral part of an optical fiber in this part. CONSTITUTION:Minute metallic pieces 3 are laminated and stuck on the rear end part of a ferrule of the connector and the outside peripheral surface in a part brought into contact with said rear end part and in a part near said rear end part. A metallic wire 4 as a material is sparked at a point 41 to crash minute metallic pieces 3 into surfaces of the optical fiber, the ferrule, etc., from an injecting nozzle 6 by a cooling gas 5 of intense pressure, thereby forming a laminated body 3. In this structure, an external force is not applied to only the optical fiber because frequent bending stress of the external force applied to the ferrule 2 acts upon the laminated body 3 similarly. Since individual minute metallic pieces of 5-50 microns size of the solid laminated body are thrusted into the outside peripheral surface of the optical fiber, the laminated body is not peeled and the optical fiber and the laminated body are not moved in independently of each other even if the optical fiber is bent.

Filed: 1990-09-17
Abstract: PURPOSE:To improve the reading accuracy of a subscanning direction without receiving the constraint of the picture element pitch of a line image sensor by executing the reading of the subscanning direction at space frequency higher than the case of a main scanning direction. CONSTITUTION:The reading accuracy of a main scanning direction is defined by a picture element pitch X of a line image sensor 62 in the same way as the conventional practice and 1mm is divided into 8 picture elements and is read. Then, 1mm is read by the 16 picture elements at the density twice as much as the main scanning direction in a subscanning direction. Concretely, scanning is executed over 16 times from first reading (R1) to 16th reading (R16) by feeding paper for 62.5mum in a B direction. Thus, the reading accuracy of the subscanning direction can be improved with using the line image sensor equal to the conventional one without receiving the constraint of the size of the picture element pitch.
