Title: Oil feeder with judging faculty of oil kinds
Inventor: MOTOHASHI TOSHIAKI
IPC: B67D7/32
Filed: 1990-07-17
Abstract: PURPOSE:To obviate the necessity of a sampling mechanism for guiding vaper to a gas senser and to prevent mis-judging of oil kinds, by providing a sender of fuel oil data equipped at the oil feed cap, on a placing base. CONSTITUTION:A pacing base 9 of an oil feed cap is formed as a recess at a part of the upper face of a part of an oil feeder box 10. A senser 1 equipped near the placing base 9 of the oil cap outputs signals to a controller 7. The oil feed cap is removed from the fuel oil tank of an automobile to feed oil and placed on the placing base 9 previously specified. In this way, since this senser 11 outputs some signals regardless of kinds of oil, the controller 9 detects that the oil feeding cap is removed and placed on the placing base 9. In this way, oil kinds are read in accordance with the data of an oil kind indicator F of the oil feed cap A by the actuation of senser 11 and compared with previously registered oil kinds.

IPC: B22F9/28
Filed: 1987-07-31
Abstract: PURPOSE:To avoid large-scaled apparatus, to reduce gas consumption and to produce a product having suitable size to high density magnetic recorder by reacting reaction gas under the specific reduced metal superfine powder by gas phase chemical reaction method. CONSTITUTION:At the time of producing the magnetized metal superfine powder by chemical-reacting vapor of one or more kinds of the magnetized metal compounds, the reaction gas is reacted under the reduced pressure at 50-600Torr. By this method, the gas consumption for obtaining the magnetized metal superfine powder having the specific particle size can be reduced. Further, rapid cooling is easily executed and particle growth of the magnetized metal superfine powder is effectively restrained. In the case of <50Torr the reaction pressure, the diffusion speed of the magnetized metal compound is to fast, and the deposit stuck to the furnace wall face is increased. On the other hand, in the case of >800Torr the reaction pressure, the gas consumption can be reduced only by a little, compared with increasing cost of the apparatus for obtaining reducing pressure and control of particle size of the superfine powder is not so facilitated.

Title: Still picture transmission equipment
Inventor: SUDA SHINICHIRO
IPC: H04N7/12
Filed: 1987-07-29
Abstract: PURPOSE:To prevent the disorder of a received picture by using an internal clock even at the time of receiving picture data. CONSTITUTION:At the time of receiving the picture data from an opponent, a carrier signal S1 is extracted from a received AM signal Sa, and instead of making the extracted signal S1 into a clock and writing the picture data to a memory 41, a frequency-dividing signal S1 from a dividing circuit 84 is made into the clock and the picture data are written to the memory 41. Consequently, even though an instantaneous interruption and a pulse noise are generated in a picture data period T6, the increment of a writing address to the memory 41 can not be suspended. Thus, the dislocation of a displayed picture due to the instantaneous interruption and the pulse noise can be prevented.

Title: Chip for metal cutting round saw
Inventor: NISHIO SATORU
IPC: B23D61/04
Filed: 1988-07-29
Abstract: PURPOSE:To permit a beautiful cut face of good precision to be formed and a longer life to be stabilized by decreasing chipped scrap in width to the extent of passing through the first rake face so as to discharge the same which is curled after decreased greatly in width during outflow over the second rake face and a stage. CONSTITUTION:When a metal is cut by a round saw which has a chip 13 brazed in each cutting edge house 15 of a base metal 11, chipped scrap cut by the first rake face comes to be thin scrap in a center portion 13f and thick scrap created on both sides thereof. Then, 13f has low frictional force so that the scrap is less deformed and kept thin, and grater frictional force with approximating both sides so that the scrap is compressed and increased in thickness. Also, the scrap on both side portions is promoted to flow into the center portion, therefore right-and-left scrap content is decreased moderately. Additionally, the scrap, in the process of flowing over a recessed portion 13h and the second rake face 13b, has both wings lifted up by a high 13b on both sides, put on a stage 13g in the state of floating over 13h, and bent largely by a stage with rising circular arc in a cross direction to be curled. At this time, the scrap content is greatly decreased to facilitate bending and deformation for allowing deformation in crosswise uniformity.

Both the glass outer tube 2 and light emitting tube 1 have a nearly circular cross section, and they are desirably arranged concentrically with each other. Structure is simplified by integration, and mechanical strength is improved by the synergism of the both, and thickness can be reduced, and build up of beam flux at the time of starting in the low temperature atmosphere is improved by the temperature holding work due to the pressure reduction inside of the glass outer tube 2.  At least one of the light emitting tube 1 and the glass outer tube 2 is desirably provided with a circumferential curve part 3, and generation of crack is thereby prevented.

Abstract: PURPOSE:To enable high-speed driving by perfectly resetting into an antiferroelectric state at a high speed within a selection period. CONSTITUTION:This driving method has at least a first scanning period Se and second scanning period Sf. The voltage waveforms of the first scanning period Se and the second scanning period Sf are symmetrical to OV. The first scanning period Se and second scanning period Sf respectively have at least a selection period Sc and non-selection period Sd. A reset pulse Vrp is impressed in the first phase Sa of the selection period Sc and a select pulse Vs in the second phase Sb of the selection period Sc to a scanning electrode.

The absolute value of the voltage of the reset pulse Vrp is smaller than the absolute value of threshold voltage and larger then OV. In addition, the polarities of the reset pulse Vrp and the select pulse Vs within the same selection period Sc are the same polarity.
