  • Patent number: 6242292
    Abstract: In producing a semiconductor device by annealing with laser light irradiation, while a linear laser light is scanned in a direction perpendicular to a line, the annealing is performed for a semiconductor material. In this state, since an anneal effect in a beam lateral direction corresponding to a line direction is 2 times or more different than that in the scanning direction, a plurality of semiconductor elements are formed along a line direction in which the linear laser light is irradiated. Also, a line direction connecting the source and drain region of a thin film transistor is aligned to the line direction of the linear laser light.

  • Patent number: 6152024
    Abstract: An apparatus and method of producing a food product is disclosed. The food product is placed inside of an air-tight chamber, in which the food product is to be cooked, wherein steam is generated from a source of water and is introduced into the cooking chamber. The steam heats the inside of the cooking chamber and serves as a heat transfer media to heat the food product as well as a color and flavor transfer media to color and flavor the food product. That is, a flavoring and coloring additive, such as liquid smoke, may be added to the water utilized in generating the steam in order to flavor the food product being cooked. The steam then transfers the flavoring and coloring additive to the food product which condenses on the food product adding flavor and color to the food product.

  • Patent number: 6134331
    Abstract: An electronic stethoscope consisting of a transducer, an amplifier and a headphone will be better adapted to the habits of use of doctors when it is supplied with filters which mimic the transfer function of acoustic stethoscopes. Thus, the signals heard will correspond to those learnt, and thereby the advantages of greater amplification and elimination of noise sources may be fully utilized. Hence there is a possibility for extended digital signal processing which may furthermore compensate for the hearing loss of each individual doctor.

  • Patent number: 6125326
    Abstract: A combination of a main navigation apparatus 2 which is fixed to the vehicle and a sub-navigation apparatus 3 which is detachable from the vehicle. When the sub-navigation apparatus 3 is attached, map information and current position information is displayed on a main display 25 under control of a sub-control unit 1, and state of the vehicle is displayed on a sub-display 33. When detaching the sub-navigation apparatus 3 from the vehicle, area map information necessary for waking outside of the vehicle is transmitted from an on-vehicle database 22 to a RAM 32. When the sub-navigation apparatus is detached from the vehicle, if the operation switch 36 is turned on, either the sub-display 33 or a speaker 34 is operated by an sub-navigation unit in a saving power control mode in which either the sub-display 33 or the speaker 34 is operated only for a predetermined period of time since the operation switch 36 is turned on.

  • Patent number: 6116273
    Abstract: Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves that can be calibrated outside of the injector prior to the installation thereof.

  • Patent number: 6105308
    Abstract: In the horticulture, large amounts of growth substrate blocks are used for the growing of cuttings, and these blocks should preferably be surrounded by a paper like casing. For the very manufacturing of these block packaging the casing material should be of a reasonably strong and good quality, which, however, may cause problems later on, when the plant roots during their growth pack against the casing wall. With the invention there is used for the casing a dual fraction material comprising partly a long-time durable, open web and partly a reinforcing and more or less web filling or covering material of a type that is brought to disintegrate either in the manufacturing process or in a suitably rapid manner by the natural influences, in particular moisturing, to which the blocks are exposed when taken in use. Thereafter, the said web may hold the block together without preventing root penetration.

  • Patent number: 6093935
    Abstract: In a process for manufacturing a thin film transistor having a semiconductor layer constituting source and drain regions and a channel forming region, by the semiconductor layer being made thinner in the source and drain regions than in the channel forming region a structure is realized wherein, at the boundary between the source region and the channel forming region and the boundary between the drain region and the channel forming region, portions where electric field concentrations occur are displaced from the portion where a channel is formed. By reducing the OFF current (the leak current) without also reducing the ON current, a high mutual conductance is realized.

  • Patent number: 6093934
    Abstract: Nickel is selectively held in contact with a particular region of an amorphous silicon film. Crystal growth parallel with a substrate is effected by performing a heat treatment. A thermal oxidation film is formed on the silicon film by performing a heat treatment in an oxidizing atmosphere containing a halogen element. During this step, in the silicon film, impurities included such as oxygen or chlorine, are segregated with extending along the crystal growth, the crystallinity is improved, and the gettering of nickel element proceeds. A thin-film transistor is formed so that the direction connecting source and drain regions coincides with the above crystal growth direction. As a result, a TFT having superior characteristics such as a mobility larger than 200 cm.sup.2 /Vs and an S value smaller than 100 mV/dec. can be obtained.

  • Patent number: 6091059
    Abstract: A low cost, compact heat roller device is provided which includes a heat generating resistance for increasing the temperature of the heat roller wherein the heat generating resistance is divided into two parts in order to correspond to passage widths of different recording materials. The heating power of one of these heat generating resistances is changed and the temperature increase of a non-paper transport area of the heat roller is suppressed. Specifically, the heat roller device includes a heat roller and a press roller opposite the heat roller, two heat generating resistances formed on an outer surface of the heat roller which generate heat independently of one another, a common electrode for supplying current and separately arranged additional supply electrodes. The time during which the respective heat generating resistance is on, is changed, in relative terms, according to the object to be heated, and thus the heating power is changed.

Each data processing interface includes a processor which operates in the transmitting mode to add an error control correction data format to data received from an external data source. The data is divided into packets and provided to a modem which is uniquely operated to eliminate the action of the modem scramble system and to remain active in spite of a carrier signal loss. The modem is deactivated or disconnected by a disconnect signal from the processor, and when carrier signal loss occurs, this disconnect signal is provided only after the lapse of a delay period without the resumption of the carrier signal.
