A liquid fuel burning device comprising a wick for sucking and burning a liquid fuel contained in a fuel tank by capillarity and a vent passage which is provided in a portion other than a fuel passage used by the wick and allows communication between an interior of the fuel tank and the outside air at least during combustion.
摘要:
A liquid fuel burner has a wick for drawing up by capillarity of a draw-up section liquid fuel composed mainly of alcohol contained in a fuel tank and for burning it at a tip flame-producing section, a wick holder for holding the wick, an igniter for lighting the wick and a closure cap for preventing evaporation capable of sealing the wick openably and closably, and a flame-producing section of the wick is made noncircular in cross-sectional shape to increase the surface area exposed above the wick holder.

A microcomputer MCU adopting the general purpose register method is enabled to have a small program capacity or a high program memory using efficiency and a low system cost, while enjoying the advantage of simplification of the instruction decoding as in the RISC machine having a fixed length instruction format of the prior art, by adopting a fixed length instruction format having a power of 2 but a smaller bit number than that of the maximum data word length fed for instruction execution. And, the control of the coded division is executed by noting the code bits.
摘要:
In a combustion appliance provided with a combustion wick for sucking up a liquid fuel by the utilization of capillarity and burning it, the combustion wick is constituted, such that a flame length in accordance with the application of the combustion appliance can be obtained, such that little change in fuel feed rate may occur due to a change in amount of residual fuel, and such that the flame length may not change. The combustion wick (6) comprises a sucking section (61) for sucking up the liquid fuel and a heat-resistant burning section (62), which are made from different materials and connected to each other.

A division method and circuit performs a division for signed data by adding or subtracting a divisor to or from the dividend or the partial remainder from the division, according to the sign of the divisor or the dividend and the partial remainder to acquire a new partial remainder. The division is repeated a predetermined number of times in which a quotient bit is acquired according to the sign of the acquired partial remainder or the divisor. The dividend is corrected by subtracting 1, which is the significance of an LSB of the corresponding dividend, from the dividend when the sign of the dividend is negative, and the corrected dividend is used for the division processing.

An external sync signal generated by a clock generation circuit inside a single-chip microcomputer is supplied to an external terminal of this chip. The external sync signal is necessary in an external expansion mode but not in a single-chip mode. Therefore, the external sync signal is supplied to the external terminal through a control gate while a suitable control signal is inputted to a control terminal of the control gate. According to this circuit construction, control can be made in such a manner that the external sync signal is not supplied to the output terminal in the single-chip mode. As a result, it becomes possible to prevent noise from entering a signal supplied to an adjacent pin through a coupling capacity between the external terminals in the single-chip mode, and to reduce consumed power of an output buffer circuit which is disposed between the control gate and the external terminals.
摘要:
A method of optically coupling one end of an optical fiber to a waveguide formed on a substrate, such that an end portion of the fiber is fitted in a groove formed in the substrate. The groove is formed by forming a beam-shielding mask having a cutout, on the substrate such that the cutout is aligned with a part of the substrate in which the groove is formed, and by irradiating the above-indicated part of the substrate with a high-energy beam. Alternatively, the groove is formed by a cutting tool. An inclined end surface of the groove left uncut by the tool may be irradiated with a high-energy beam, through a beam-shielding mask which has a cutout aligned with the inclined end surface. The end of the optical fiber, which has a flat face or has a coned or hemi-spherical shape, is positioned for optical coupling with a portion of the waveguide which is exposed to the groove.
