Title: Picture display device
Inventor: SATO YUICHI
IPC: H04N5/66
Filed: 1985-06-28
Abstract: PURPOSE:To reduce a picture on display element with a simple constitution by sampling and storing a picture signal interlaced at every two lines and changing the reading speed of the stored picture signal. CONSTITUTION:When the picture is displayed with reducing it to 1/2, a mode signal becomes '1' and G1 and G2 out of signals outputted from a gate controller 54 are outputted as '1' alternately at every horizontal scanning. When the G1 is '1', a decoded video signal VD is inputted to an analog shift register 55 with synchronizing a switching signal approx.=H. By setting a frequency that reads data from the register 55 as the one doubled of an inputted frequency, it is possible to set the length of the picture in a lateral direction to 1/2. Also, when an MD signal is '1', so that the output UA of a circuit 46 becomes '1 at a ratio of one to two horizontal scannings, it is possible to display in reduction in a vertical direction by setting the number of vertical scanning lines at both an odd field and an even field to 1/2.

Title: Electroconductive fiber and its production
Inventor: KAWACHI HIROYUKI
IPC: D02G3/04
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain an electroconductive fiber having low electroconductivity under the application of low voltage and high electroconductivity under high voltage, free from the problems such as circuit shortage under low voltage and exhibiting antistatic property under high voltage. SOLUTION: A voltage dependence of electroconductivity is determined by varying the volume content of electroconductive fine particles in a conductive layer of an electroconductive fiber. The curve showing the voltage dependence of the electroconductivity is shifted in horizontal direction and the synthesized curves are superposed with each other. The electroconductivity under low voltage beyond the measurable limit and the volume content of the conductive fine particles in the conductive layer are determined from the produced master curve. This electroconductive fiber has an electroconductivity of <=1×10<-6> S/cm under a voltage of 5V/cm and >=10<-5> S/cm under 1,000V/cm measured by the above method.

Abstract: PURPOSE:To exhibit a sufficient vibration isolation effect without increasing the height of a parts feeder, by providing such an arrangement that two troughs attached to the support sections of drive springs which are coupled to a base by means of leaf springs are subjected to excited vibration, and therefore, component parts are transferred in the opposite directions. CONSTITUTION:Leaf spring attaching plates 30 respectively secured to the bottoms of return and feed troughs 2, 22 are coupled to a common leaf spring support section 33 by means of a pair of front and rear drive leaf springs 32, 31, respectively. Vibration isolating leaf springs 30, 29 which connect the support section 33 to a base 40 therebelow are fixed at both ends thereof to the support section 33 and the base 40, respectively. When electromagnetic coils 37, 38 are energized so that the troughs 22, 21 are subjected to vibration the reaction force of which is transmitted to the support section 33 through the springs 31, 31. Since the vibration transmitted through the spring 31 has a phase reverse to that of the vibration transmitted through the spring 32, the horizontal components of two kinds of vibration are canceled out with each other while the vertical components there of are added together. Therefore, the bending motions of the spring 31, 32 due to the reaction of the vertical components may be reduced by increasing the lengths of the springs to reduce the transmission rate of the reaction force to the base 40.
