Abstract: PURPOSE:To improve the distorsion of an output waveform, by reducing a carrier frequency in an area wherein a frequency is low and an output voltage is low. CONSTITUTION:When an output voltage is received by a micro-processor, a CPU 21 operates an output pattern and the operated data thereof is stored into a data memory 22. A frequency deciding circuit 23 decides the operated data, stored into the data memory 22, whether it is smaller than a lower limit value or not, then, an output voltage deciding circuit 24 decides the output voltage whether it is smaller than the lower limit value or not when said operated value is smaller than said lower limit value. When the output voltage is decided that it is smaller, a frequency operating circuit 25 determines to reduce a carrier frequency and the data is stored into the data memory 22. These data are taken out of a take-out circuit 27 and outputted to an output port 28.

Filed: 1989-06-29
Abstract: PURPOSE:To raise the thermal conductivity of the piston head part and lessen the clearance at a skirt part by forming the skirt in Fe alloy constitution, and forming the lead in Al alloy constitution, both through power injection molding. CONSTITUTION:Thermoplastic resin binder, plasticizer, lubricant are added to Fe alloy powder and Al alloy powder, and they are kneaded and granulated into particles sizes 2-5mm. Then the Fe alloy particles 1a, its admixture 3a with Al alloy particles, and the Al alloy particles 2a are cast into an injection molding machine 4, the sequence named being identical to the order of injecting. The material is heated at approx. 150 deg.C, fluidified, cast into the cavity of a mold 5, and turned into three layers, i.e., a skirt 1, middle part 3, and land 2 in the sequence as named. The resultant is defatted and sintered to yield a work for piston, which is subjected to necessary processing. Thus the heat the lead 2 receives is transmitted effectively to a piston ring, which lessens the coefficient of thermal expansion of the skirt 1 to allow decreasing the clearance.

Abstract: PURPOSE:To prepare the title structure obtaining a stable heat generating characteristic without generating the segregation or lump of a heat generating composition, light in wt. and made usable with a soft feeling, by receiving the heat generating composition having a fibrous iron material partially contained therein in a support bag having air permeability. CONSTITUTION:A support bag 10 is molded using a sheet obtained by laminating an outer layer 1 composed of a nonwoven fabric to an inner layer 12 composed of a polyethylene film and hermetically sealed by heat-sealing the united part 13 thereof and vent holes 14 are provided to the front and back surfaces of said sheet.

Filed: 1987-07-08
Abstract: PURPOSE:To prevent a main shaft from charging with static electricity by providing conductivity partially or entirely to a rolling member to be assembled between inner and outer rings of a rolling bearing. CONSTITUTION:A rolling bearing 12 comprises an inner ring 12a, an outer ring 12b and a rolling member 12c. The rolling member 12c is made by coating a conductive ceramic or a steel ceramic with metal.

Furthermore, high frequency noise due to electrostatic discharge can be prevented. The rolling members 12c are not required to be entirely conductive and may be formed with at least one rolling member.

Title: Shortened antenna element
Inventor: NEMOTO YOSHIAKI
IPC: H01Q9/06
Filed: 1985-07-31
Abstract: PURPOSE:To shorten the whole length of an antenna element and to produce a transmission/reception antenna for low frequency comparatively inexpensively and simply by forming a continuous rectangular wave-like conductive circuit on a cylindrical or polyhedral insulating material. CONSTITUTION:A conductive part fixed on the cylindrical or polyhedral insulating plate 1 forms continuous rectangular waves as a conductive circuit and wound around the insulating material 1 so as to be repeatedly folded at respective fittings 3. It is preferable to set up the width of the rectangular wave-like conductive circuit to about 3-5mm and a good result is obtained when the interval between respective rectangles is set up almost equally to the width. When a dipole antenna is formed by a shortened antenna element 9 on which such kind of a continuous square wave-like conductive circuit is formed, an antenna impedance matching box 10, a feeder 11, etc., the whole length of the antenna element can be shortened. Consequently, it is unnecessary to secure a wide space for the setting of the antenna and the low frequency transmission/ reception antenna can be comparatively inexpensively and simply produced.

Abstract: PURPOSE:To improve the durability and the smoothness in absorption of deformation of a connecting body by connecting the supporting flange of a furnace body and the lower flange of a trunnion ring by means of a connecting member via spherical bearings bodies. CONSTITUTION:Spherical bearing bodies 27, 28 are provided to the lower flange 14 of a trunnion ring 3 disposed to a converter body 2 and a supporting flange 4 stuck to the body 2 respectively. The bodies 27, 28 are connected by means of a connecting member 30 and both flanges 4, 14 and the member 30 are made  freely pivotally movable. Thus the inter-connection distance is made long, and  the deformation such as thermal expansion and secular change of the body 2  are absorbed freely with small rates of slipping. Therefore this connecting  mechanism 5 supports the body 2 surely whether the body 2 is in an erecting  state or in an inclined state.
