Title: Production of microfiber
Inventor: KITAGAWA TAKAO
IPC: D01F6/04
Filed: 1978-01-23
Abstract: PURPOSE: An olefin polymer is emulsified using a specific organic solvent and jetted from orifices combined in series to produce microfibers having good entangling, fiber bonding, water-retention, and dispersing-in-water properties.  
     CONSTITUTION: A polymer solution A prepared by dissolving an olefin polymer in an organic solvent containing more than 2% of a component boiling at from-10 to + 45°C and more than 1% of saturated or unsaturated cyclic hydrocarbons is mixed with a polar-solvent solution B containing solutes being incompatible with solution A and soluble in the polar solvent to form an emulsion. The emulsion is extruded through paths consisting of a plurality of orifices combined in series into the low-pressure zone. The resulting microfibers are increased in specific surface area, and hydrophilic properties and improved in dispersity in water, thus giving sheets with increased strength and opacity and light scattering coefficient.

Title: Multiple reflector antenna sharing multi-frequency band
Inventor: MORI ISAO
IPC: H01Q15/16
Filed: 1984-01-17
Abstract: PURPOSE:To increase the beam width at a high frequency band without deteriorating the radiation characteristics of a low frequency band, by using a frequency selecting surface plate FSRS to form a subreflector and also providing another subreflector at the rear side of the first subreflector. CONSTITUTION:An FSRS plate forming a subreflector 2' functions as an HPF to reflect a low frequency band Fl of the radio wave radiated from a primary radiator system 3 and to transmit a high frequency band Fu. Thus the FSRS plate gives the radiation characteristics of the normal beam width to a low frequency band. While a concave subreflector 4 irradiates through its radius (ru) the center part of a main reflector 1 against a radio wave of a band Fu. The beam width of an antenna is adversely proportional to the opening radius of the reflector 1. Thus it is possible to increase the beam width at a high frequency band by reducing the radius (ru) of a reflector 3.

Title: Driving circuit for thermal head
Inventor: KANO HIROSHI
IPC: B41J2/36
Filed: 1987-01-14
Abstract: PURPOSE:To uniformize recorded density through preventing each heat generating element from being thermally affected by the adjacent heat generating elements, by dividing M heat generating elements N blocks each of which consists of M/N heat generating elements (mK, mK+N; mK+2N...mK+(M/N-1)N), and driving the elements on a block basis. CONSTITUTION:A ring counter 2 is initialized by a presetting signal PS, and in the condition where first and second selection signals BS1, BS2 are L, recording data D consisting of 512 bits of data d1-d512 is applied to an AND circuit 4 synchronously with a clock signal CLK. At this time, a selector 3 is supplied with an output from a No.0 terminal of the counter 2, so that the recording data d1, d5...d509 is inputted to a shift register SR, and heat generating elements m1, m5...m509 are driven synchronously with a latch signal LA. The selection signals BS1, BS2 are changed in the sequence: H and L, L and H, and both H, so that the heat generating elements are sequentially driven on a block basis according to the changes in the selection signals. Thus, since all of the heat generating elements are driven in a discrete state, each of the elements is not thermally affected by the adjacent elements, and a uniform density is obtained.
