If a temperature of a heat roller 12 rises abnormally, a thermostat 54 operates. When the thermostat 54 operates, a conduction path to an excitation coil 91 of a relay 90 is cut off so that a normally open contact 92 of the relay 90 can be operated. When the normally open contact 92 operates, the supply path of a drive signal supplied from a frequency variable oscillator 81 to a transistor 63 is cut off. By the cut-off, a high-frequency current does not flow through coils 14a to 14c; therefore, induction heating with respect to the heat roller 12 is stopped.

A tooth brushing device with a video scope including a video scope having a prism mirror 10 and an objective lens 9 that form light from an object into an image, a CCD unit 8 that converts the light formed into the image, into an electric signal, and a handle section 7 held by an operator, a tooth brush having a brush section having a cavity portion 4 formed therein and a handle section held by the operator, and a display section for displaying an image picked up by the video scope, in which the handle section of the toothbrush is integrated with the handle section 7 and the prism mirror 10 is arranged where a clear image of a tooth to be brushed by the operator is picked up by the video scope. When images are picked up through the cavity portion 4 formed in the brush section and a toothbrush section and an image pickup section are independently installed in the handle section 7, images can be picked up even during a tooth brushing operation.

A method of the present invention is a fluorescence polarization method at multiple wavelengths for analyzing two or more different assay-objects in a sample. The method includes the steps of: (a) providing two or more different fluorescent-labeled substances, each being a substance which is capable of specifically binding to respective one of the assay-objects and is covalently bound to a fluorochrome, wherein the fluorochromes of the fluorescent-labeled substances are different from one another; (b) allowing the fluorescent-labeled substances to bind to the two or more different assay-objects, respectively; and (c) measuring a change in the degree of fluorescence polarization which has taken place in each of the fluorescent-labeled substances by its binding to one of the assay-objects.

A beverage server comprises a tank containing water serving as a coolant and a coiled beverage duct through which beer or other beverage flows and cooling means fitted to a portion of the wall of the tank so as to rapidly cool and serve beer or other beverage discharged from the storage container. The inner wall of the tank near the portion where the cooling means is fitted is made of a material having a high thermal conductivity, whereas the inner wall of the tank near the beverage duct is made of a material having a low thermal conductivity. A sensor is provided near the beverage duct to obtain information for controlling the cooling means. This simple beverage server assures stable serving of beverage at a suitable temperature. Another sensor is provided near a portion of the tank wall where the cooling means and a controller to controls the action of the cooling means based on the information from the sensors are also provided. The cooling means works at full capacity when one or both of the sensors have detected the melting of the coolant. This eliminates the risk of trouble due to cooling capacity deficiency even after a long interruption of cooling.

It is intended to present a sensor capable of labeling with more dyes, applying the labeled protein in immunochromatography making use of antigen-antibody reaction, and having an excellent sensitivity. In a buffer, a protein and a first covalent bonding compound that can react with this protein are reacted to prepare a protein conjugate, then a cyanine labeling dye is added in the buffer containing the protein conjugate, and the protein conjugate and cyanine labeling dye are reacted to prepare a dye labeled protein conjugate. Alternatively, in a buffer solution, a protein and a cyanine labeling dye are reacted to prepare a dye labeled protein, then a first covalent bonding compound that can react with the protein is added in the buffer containing the dye labeled protein, and the dye labeled protein and first covalent bonding protein are reacted to prepare a dye labeled protein conjugate.

An optical disc adapted so that concentrical or spiral guide grooves are formed at a base and emboss shaped pits are molded between these respective guide grooves is disclosed. In this optical disc, depth of pit is set so that the push-pull signal by the pits is caused to have reverse polarity with respect to the push-pull signal by the guide grooves. For example, when wavelength of reproduction laser beams is .lambda., refractive index of the base is n, and track pitch is t, the depth Dp of the pit is set so as to fall within the range 0.32 .lambda./n.ltoreq.Dp.ltoreq.0.51 .lambda./n, the width Wp of the pit is set so as to fall within the range 0.27 t.ltoreq.Wp.ltoreq.0.36 t, and the depth Dg and the width Wg of the guide groove are respectively set so as to fall within the ranges 0.0875 .lambda./n.ltoreq.Dg.ltoreq.0.1625 .lambda./n and 0.27 t.ltoreq.Wg.ltoreq.0.36 t.
摘要:
A kerning method for adjusting a position of an object character relative to an immediately preceding character acting as a reference character, in arranging at least two characters in a predetermined arranging direction based on character frames, i.e. imaginary bodies, including character patterns or faces therein. The method comprises the steps of designating a desired space as a designated facing space between the faces, adding, as part of the faces, correction lines extending in a direction perpendicular to the arranging direction to the respective imaginary bodies of the reference character and the object character, computing a minimum facing space between the reference character and the object character to which the correction lines have been added, computing a space reduction amount for the added object character with respect to the added reference character to bring the minimum facing space into agreement with the designated facing space, and moving the object character toward the reference character by the space reduction amount computed.
摘要:
A power supply circuit for an integrated-circuits chip includes variable resistors for establishing an internal voltage for the chip. The internal voltage is variable with the variable resistors and compared by a comparator to a test voltage supplied from an external test circuit. A first buffer amplifier, powered by an externally supplied voltage, amplifies the output of the comparator to produce output voltages of opposite polarities. A second buffer amplifier, powered by the externally supplied voltage, amplifies the output voltages of the first buffer amplifier to supply an output voltage to the test circuit. In a modified embodiment, a second voltage source is additionally provided to establish a second internal voltage higher than the internal voltage produced by the first reference voltage source. The first buffer amplifier is powered by the second internal voltage, instead of by the first internal voltage, to amplify the output of the comparator.
