Abstract: In a method for determining a groove machining process based on numerical control information generating functions, a groove machining process is automatically determined based on characteristics of shape elements adjacent to groove shape elements as well as the shapes of the groove shape elements. The groove machining process can therefore be easily optimized.

Abstract: In a display device having a plurality of scanning-side electrodes arranged in one direction, a plurality of data-side electrodes arranged in a second direction intersection the first direction, and dielectric layers interposed therebetween, a modulated voltage the magnitude of which is varied according to the emission or non-emission of light is applied to the data-side electrodes, while applying a write voltage in line sequential fashion to the scanning-side electrodes, thereby performing the display control. In such a display device, the polarity of the voltage applied between the data-side electrode and the scanning-side electrode corresponding to the picture element to be driven for light emission is reversed one or more times during the period in which the write voltage is being applied to the scanning-side electrode. This serves to reduce the modulated voltage and the write voltage, thus contributing to the reduction in power consumption.

Abstract: A heat transfer sheet comprising a base film and a hot melt ink layer formed on one surface of the base film, said hot melt ink layer comprising one or more components which impart filling to the printed areas of a transferable paper during transferring. Another type of a heat transfer sheet comprising a base film, a hot melt ink layer laminated on one surface of the base film, and a filling layer laminated on the hot melt ink layer, said filling layer comprising one or more components which impart filling to the printed areas of a transferable paper during transferring. According to the heat transfer sheets, high quality printing can be attained even at a high speed without any staining.

Abstract: The tool feed rate correcting method for numerical control system and the apparatus therefor according to this invention correct the feed override values using an override correction coefficient which is calculated from the displacement information of the tool and control the tool feed rate so that machining loads can be maintained within predetermined range irrespective of the machining conditions. This invention is therefore effective in realizing machining with a high efficiency as well as in reducing the cost.

Abstract: A tool retracting method and apparatus is for retracting a tool in an NC machine tool upon the detection of the occurrence of an abnormal machining condition during operation of the NC machine tool. The tool retraction direction is determined which is counter to the direction of the cutting load acting on the work at the moment of the occurrence of the machining abnormality, so that the tool can be promptly retracted without interfering with the work.

Abstract: A heat-sensitive transfer recording material for use in a heat-sensitive transfer recording means such as a thermal printer is provided. The recording material comprises a heat-sensitive transfer ribbon having a heat-fusible ink layer provided on the surface of a polyester base film and a heat-resistant protective layer. The heat-resistant protective layer comprises (1) a chlorinated product of a 4-methyl-1-pentene polymer or a derivative thereof and an amorphous linear saturated polyester or (2) at least one member selected from the group consisting of chlorinated products of acid-modified 4-methyl-1-pentene polymers and acid-modified 4-methyl-1-pentent/.alpha.-olefin copolymers.

Abstract: A hand-held vacuum cleaner comprising a dust case having an upward opening and an air-permeable filter wall formed as at least a portion of its structural wall, the dust case being removably fitted in a dust collecting recess formed in the main body of the cleaner, a partitioning member having a suction opening and removably fitted over the opening of the dust case to cover the opening, and a closure pivoted to the cleaner main body and openably closing the opening of the recess except the suction opening of the partitioning member. A paper filter can be held between the dust case and the partitioning member.

Abstract: A heat transfer sheet comprises a sheet for heat transfer recording which transfers ink on a base sheet onto a recording paper, said ink containing a compound represented by formula (I) shown below as a binder component:C.sub.n H.sub.2n+1 CH.sub.2 Y (I)wherein n is an integer of 21 to 50, and Y represents OH, SO.sub.3 H, C.sub.6 H.sub.5 or COOH, or a Ca, Al or Zn salt thereof.

Abstract: A heat-resistant thermal transfer sheet comprising a base film provided on one surface thereof with a hot melt ink layer and with a heat-resistant protective layer on the other surface thereof. The heat-resistant protective layer is produced from a composition comprising (a) a thermoplastic resin having an OH or COOH group, (b) a polyamine or polyisocyanate, and (c) a thermoplastic resin, or a composition based on a silicone-modified resin. The heat transfer sheet of the present invention prevents sticking and blocking problems and makes it possible to carry out printing smoothly.
