Abstract: A mounter for a manufacturing management method suppresses an occurrence of inventory shortage or excess inventory as much as possible, and provides energy savings when manufacturing is not performed at full capacity. A throughput determining step acquires manufacturing information included in a manufacturing plan while manufacturing equipment is manufacturing mounted boards and determines a throughput of the manufacturing equipment for the mounted boards based on the manufacturing information while the manufacturing equipment is manufacturing a sequence of the mounted boards. A manufacturing condition determining step determines a manufacturing condition for decreasing power consumption of the manufacturing equipment within a range of throughput not lower than the determined throughput in the case where the throughput determined in the throughput determining step is equal to or lower than a current throughput of the manufacturing equipment.

Abstract: A simulation apparatus for simulating a pipeline processor including a pipeline simulation unit and an instruction simulation unit. The simulation apparatus includes a pipeline simulation unit is operable to simulate a group of instructions comprising a plurality of instructions to be executed simultaneously. The instruction simulation unit is operable to simulate a sequential execution, of the group of instructions on an instruction-by-instruction basis, based on the simulation result performed by the pipeline simulation unit. The instruction simulation unit generates the simulation result by undoing the simulation where an instruction included in the group of instructions that has just been simulated by the pipeline simulation unit.

Abstract: The object of this invention is to reduce the cost of an amplification device that has a distortion detection loop that uses an amplifier to amplify the signal subject to amplification and detect the distortion arising in said amplifier, and a distortion removal loop that removes the distortion detected by the distortion detection loop from the signal amplified by said amplifier.

Abstract: There is provided a method of deep drawing magnesium material, which material is superior in environmental compatibility and energy saving properties. The deep drawing method of the invention uses a die having a male mold 1 with a convex portion, and a female mold having a concave surface. In the method of the invention, a mounting table is placed between the male mold and the female mold for supporting a magnesium plate, and a layer of a plurality of thin resin films is placed on the magnesium plate. Further, a central portion of the magnesium plate is kept in contact with the convex portion 12 of the male mold, and the concave surface of the female mold is moved to cooperate with the convex portion of the male mold so that deep draw forming of the magnesium plate is achieved.

According to this method, a resolution method useful for industrial large-scale production of the optically active compound of 4-[.alpha.-hydroxy-5-(1-imidazolyl)-2-methylbenzyl]-3,5-dimethylbenzoic acid, which is useful as a thromboxane synthetase inhibitor and an agent for the prophylaxis and treatment of diabetic complications, can be obtained.

Abstract: A method is provided for the control of a color tone during production of a reproduced color image by tonal conversion of a light quantity of each pixel into a halftone. The method includes setting, at a position between a highlight area and a shadow area in a color original image, a color tone control point, defining adjustment conditions at the color tone control point in terms of dot percent values of desired plural color plates. The method also includes introducing a light quantity at the color tone control point, dot percent values of the plates and desired dot percent values set in advance for highlight areas and shadow areas in the plates into a tonal conversion formula to determine values .gamma. for the plates conversion formulas are provided for converting, into dot percent values, light quantities of all pixels ranging from the highlight areas to the shadow areas.

Abstract: A video signal digital recording and reproducing apparatus includes: a rearranging section for rearranging a sequence of signals on a rectangular unit by rectangular unit basis formed by sectioning a group of pixel data on a screen of a digital video signal; an encoding section for subjecting the signals in the rectangular units to bit rate reduction; a block forming section for gathering plural number of the coded rectangular units to constitute a block of signals, and a recording the block of signals section for recording on a recording medium. The rearranging section divides the screen into plural regions, takes out the rectangular units by a certain number in order from each region, and carries out rearrangement so that mutually corresponding rectangular units which are contained respectively in adjacent blocks on the recording medium are mutually adjacent on the screen.

Abstract: A joint for end-to-end coupling of two tubular elements includes tapered coupling surfaces on the tubular elements which are bonded together by adhesive. The coupling surfaces comprise a plurality of cylindrical sections of gradually increasing and decreasing diameters, respectively. A plurality of axially spaced-apart centering rings are interposed between the tubular elements to provide proper positioning thereof and to facilitate injection of bonding material between the coupling surfaces. A series of axially spaced-apart conducting rings forming part of an antenna surround one of the tubular elements and are insulated therefrom by a layer of bonding material. The conducting rings are separated from each other by toric joints and shims. Openings are provided in one of the tubular elements for injecting the bonding material under pressurized conditions, and an insulating sheath is bonded to inner peripheries of the tubular elements.

Abstract: The present invention relates to a high-strength coil spring useful for an engine and other high-strength springs requiring a high fatigue-resistance and a method of producing the same.In general, a higher tensile strength is desired for spring materials but it has been known that if a tensile strength exceeds a certain limit, a toughness and a fatigue resistance are contrarily reduced.In addition, a coil spring has been used after forming and then being subjected to a quenching treatment followed by being subjected to a shot peening treatment to add a compressive residual stress to a surface thereof but an effective shot peening treatment gives a surface roughness Rmax of 6 to 20 .mu.m, so that not only it has been impossible to remove surface defects having a surface roughness of 6 to 20 .mu.m or less but also impressions due to the shot peening have covered the surface defects to be turned into injured portions and fatigue nuclei in many cases.
