Abstract: A single fuel pump for a fuel delivery system supplies fuel from the fuel tank to a reservoir and also supplies fuel from the reservoir to the engine. The fuel pump has a single impeller having outer vanes and inner vanes radially inward from the outer vanes. The vanes are aligned with outer and inner channels in the pump housing, respectively, so that fuel may be pumped from the fuel tank into the reservoir. Fuel from the reservoir is then pumped to the engine.

Abstract: User identification name register method and device in a facsimile, capable of performing a compression coding of image signals recorded in a card for a user identification name register and transmitting the image signals as a facsimile header, thereby freely registering, as the sender identification name, not only fonts stored in a font ROM, but also any types of characters and designs which the user desires to register, so that the number of fonts stored in a font ROM is minimize.

Abstract: A method for compressing font data wherein, for example, each byte of a font is provided with a compressing code. A bit map of the font is stored in a font file which is separated into a reference byte and a comparator byte. The two bytes are compared with each other. In response to the comparison a specific compression code is assigned and stored in the compression file. In the comparison, the present byte of a font to be compressed is compared with a byte which is positioned immediately before the present byte. When no byte is positioned immediately before the present byte, the byte is compared with OOH.

Abstract: An output control circuit of a 4-burner electronics induction heating cook system comprises a unit for measuring the proportional setting time to selectively operate the timing on-off control and the frequency control of a heating load; an invertor circuit for generating a proportional time and applying this to the load; a current feedback/output adjusting circuit provided with a differential amplifier inputing a high or low level signal according to a signal from the current detector; an output setting control portion provided with a unit for comparing the signals from the circuit connected to the adjusting circuit and the saw tooth wave generating circuit and then outputing a pulse width modulation signal; an output setting control portion provided with at least one photocoupler wired in an OR configuration to control the operation of the control portion and a microprocessor connected to control the operation of the photocouplers; a base operating portion and a timing circuit for controlling an invertor cir

Abstract: A rotation angle detection circuit for a step motor providing an up/down control signal for determining positive and negative rotation of the step motor and a mask control signal for determining rotation angle of 15.degree. and 30.degree.. The circuit can correctly detect the rotation angle of the step motor by counting the pulse signals from the up/down control signal and mask control signal. It is thereby useful for application in a system which electrically measures the rotation of the step motor.
