摘要:
The invention involves a novel melamine group-containing (meth)acrylate, e.g. hexakis(2-acryloyloxypropyl)melamine, hexakis(2-acryloyloxyethyl)melamine, etc., and its polymer. Said (meth)acrylate has excellent reactivity and storage stability, and said polymer has excellent dimensional stability, durabilities (especially water resistance and moisture resistance) and surface hardness, and is useful as a molded product and a coating layer of a molded resin article. For example, a polyester film coated with said polymer has excellent adhesivity, flexibility and dimensional stability as well as high abrasion resistance, and can be used to a wide variety of uses as an abrasion resistant film.

A method of producing a printed circuit board includes: forming a metal layer on a support plate; forming a mask layer on the metal layer; forming a pattern plating having a stem as plating up to a level of the mask layer, and a cap as a portion of plating exceeding the mask layer and having an outgrowth lying over the surface of the mask layer; laminating an insulating base on a conductive circuit board constituted by the support plate, the metal layer and the pattern plating to form a circuit board intermediate in which the pattern plating is buried in the base; removing the support plate and the metal layer to form an exposed surface; and mechanically polishing the exposed surface until the stem of the pattern plating is removed, to increase the width of the conductive pattern on the exposed surface.

An iron rotor core includes a first permanent magnet in an outer peripheral portion of the iron rotor core, second permanent magnets on both circumferential sides of the first permanent magnet and arranged in a generally V-shaped configuration opening radially outward, and a first region provided opposite to the first permanent magnet radially inside the region between the second permanent magnets and having a low magnetic permeability. A q-axis magnetic flux path is formed in an iron core region among the first permanent magnet, the second permanent magnets and the first region, and a central portion thereof is formed between the first permanent magnet and the first region, and entrance/exit portions of the q-axis magnetic flux path formed between the second permanent magnets and second regions provided on both circumferential sides of the first permanent magnet and having a low magnetic permeability with generally the same width.

A diagnostic control device for a hybrid vehicle is provided for shortening the time required for a failure diagnosis of an evaporation purge system. After introducing the inlet-pipe's negative pressure into the evaporation purge system 51, the evaporation control unit 52 diagnoses failure states concerning the evaporation purge system 51 such as a leak by detecting changes in inner tank pressure over a prescribed time. In order to shorten such failure diagnosis control time, a motor generator 12 is driven to assist the engine when introducing the inlet-pipe's negative pressure into the evaporation purge system 51. With such assist-driving, it becomes possible to reduce engine load, therefore, the throttle valve 67 of the engine 11 can be controlled to be on the closed side, making it possible to create sufficient inlet-pipe's negative pressure. Through this, the pressure in the evaporation purge system 51 can be decreased quickly, which shortens the time for failure diagnosis in the evaporation purge system 51.
摘要:
It is determined whether an engine for a flexible fuel vehicle is in a start enabling state based on alcohol concentration of fuel supplied to the engine. When it is determined that the engine is in the start enabling state, a heater for vaporizing fuel is energized. Current flowing in the heater is compared with a reference current representing completion of warmup of the engine. When the current becomes smaller than the reference current, the heater is de-energized, and the fuel is injected to start the engine.

A flexible fuel vehicle has an engine with a fuel injector for injecting mixed fuel of gasoline and alcohol into the engine. The operation of a starter motor of the engine is inhibited for a set time period before injecting the mixed fuel from the fuel injector and the mixed fuel is circulated flowing from the fuel pump to the fuel tank for the set time period so as to sufficiently and homogeneously mix the gasoline and alcohol in the mixed fuel.

An automatic transmission has a lockup clutch for a torque converter. Concentration of alcohol is detected by an alcohol concentration sensor. The lockup clutch is engaged at a lower vehicle speed when the alcohol concentration detected by the alcohol concentration sensor is higher than a predetermined reference value.

摘要:
In Trellis coded modulation system in which an input digital signal in parallel form is encoded by a convolutional encoder which adds an additional bit to the input digital signal for error correction purpose, and a mapping circuit designated amplitude and phase for each symbol for QAM signal, the number of parallel bits at output of said convolutional encoder is the same as the number of parallel bits of an input digital signal. An input digital signal is first rate converted so that m+n bits in every T period is converted to m bits in every T' period, where T'=(m/(m+n)).T. The convolutional encoder adds n number of bits so that the total number of parallel bits is m+n, which is applied to the mapping circuit. In a receive side, a received signal having m+n bits in every T' period is decoded through an error correction decoder which provides m bits in every T' period, then, the decoded signal is rate converted to m+n bits in every T period. So, the number of parallel bits does not increase in spite of convolutional encoding, but a transmission rate is a little increased. The coding gain in the present invention is improved since the number of levels of the QAM signal is not increased although the bandwidth of the signal is a little increased because of the higher clock rate.
