Title: Variable frequency oscillator and ofdm receiver
Inventor: YAMAMOTO AKIO
IPC: H04L27/26
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a variable frequency oscillator over a broad band in which a low phase noise is realized. SOLUTION: Since a transistor noise is reduced by connecting a base of a transistor (TR) 22 to ground via a capacitive element 23 and a no load Q of a resonance circuit 29 is improved by interposing a capacitive element 24 to the connection to a resonance circuit 29, this method is effective to reduce phase noise in an oscillated signal. Furthermore, a capacitive element 25 is connected between a collector and a base of the TR 22 to suppress fluctuation of a parasitic capacitance between the collector and the base with respect to a power supply voltage, then the oscillated frequency is made stable and low phase noise is attained.

Filed: 1983-11-25
Abstract: PURPOSE:To utilize rice hulls in a perfectly combustible form, by adding particles obtained by crushing cooled melt of asphalt and petroleum pitch to uncrushed rice hulls, followed by moisture conditioning and forming into shape by extrusion. CONSTITUTION:A molten mixt. of 100pts.wt. asphalt and 67-900pts.wt. petroleum pitch is cooled and crushed. The crushed particles are added as binder to untreated rice hulls from a huller in an amt. of 5-30% and, after conditioning of moisture, the mixt. is formed into shape by extrusion under a pressure of 200-500kg/cm<2>. Although the blend ratio of asphalt and petroleum pitch varies slightly depending on the nature of asphalt, the binder is adjusted to a softening point of 110-130 deg.C. The petroleum-based binder has excellent combustibility and the resultant solid fuel has a relatively high calorific value of 4,500- 5,500kcal/kg. The fuel with a hydrophobic surface is not swollen nor broken by absorption of moisture, which is disadvantage common to conventional binderless solid fuel.

Title: Tile-shaped fiber floor material and its manufacture
Inventor: TAKASE HIDEO
IPC: E04F15/16
Filed: 1990-08-24
Abstract: PURPOSE:To contrive floor material to be very excellent in moisture- permeability and relieve expansion and shrinking with holes to be bored, by laminating micro-porous material having viscoelasticity on the rear side surface of the floor material, and by setting the moisture-permeability from the front side surface of the floor material to the rear side surface, to be equal to or more than at least 2000g/m<2>.24hr. CONSTITUTION:On tile-shaped fiber floor material, it is desirable to apply tackifier to a micro-porous film. In other words, by applying the tackifier, the close contacting property of a bearing body with laying material is further increased. Besides, it is very important to have moisture-permeability equal to or more than at least 2000g/m<2>.24hr. In other words, on dispersing water content for the material not to be uniformly steamed at a normal open air temperature, normally, moisture-permeability equal to or more than 2000g/m<2>.24hr, and preferably, moisture-permeability equal to or more than 2500/m<2>.24hr are selected. On the material having such characteristic, clear 'steaming-cancelling property' is achieved. Then, the moisture-permeability can be easily obtained by hole-boring processing the tile-shaped fiber floor material.

Title: Biodegradable string
Inventor: UEDA ATSUKO
IPC: C08L101/16
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain a string having biodegradability and satisfying mechanical characteristics so that mechanical binding is possible by using a film with specific birefringence mainly comprising polylactic acid. SOLUTION: The biodegradable string has 75 wt.% or more of its composition formed of a polylactic acid component. Polylactic acid comprises a copolymer or mixture consisting of L-lactic acid and D-lactic acid with a ratio of the D-lactic acid (D%) of 8% or less. It is necessary that relative viscosity be 1.8 or more and birefringence be 0.035 or less. Twist with the number of twists of 20 to 100 T/M is given to the string, thereby lowering frictional resistance and improving apparent ductility to enable stable binding operation. Since the string is thus mainly composed of a lactic acid based polymer having biodegradability, mold or disease and pest is not likely to grow during use, the string is not accumulated under natural environments after disposal, and it can be tied using an automatic tying machine with mechanical strength kept.

Filed: 1993-09-09
Abstract: PURPOSE:To prevent the intrusion of foams into between a filter and a filter valve by controlling the capillary force generated on an opposite section of a filter to be smaller than the capillary generated in a filter side section. CONSTITUTION:An ink tank 2 is positioned lower than a nozzle 8 jetting ink 4, and the ink pressure in the nozzle 8 is negative pressure. An area between a feed line component 7 and the ink tank 2 is sealed by an O-ring 5, and a feed line 6 for guiding ink 4 from the ink tank 2 to the nozzle 8 is formed inside the feed line component 7, and a stainless filter 14 for trapping refuses in the ink is installed in a filter box 15 located in the middle of the feed line. As the capillary force between a filter valve 10 and the opposite side of the filter valve 101 is small in the filter box 15, foams are hard to enter between the filter valve 101 and the filter 14 to suck the foams securely by a pump.
