To specify defect management information to be used in a short time in an information recording medium having a defect information area capable of recording plural sets of defect management information and a selection information area capable of recording plural sets of selection information for selecting a set of defect management information from the defect information area. The selection information includes information about a position where the latest management information at the time of writing is written, and history information indicating that the selection information is updated.

Information recording medium, defect management method, information reading/writing device and information reading device

In order to select the latest defect management information, the latest selection information first is selected by searching a plurality of selection information areas for a currently active selection information area in which the latest selection information is recorded and subsequently the latest defect management information is obtained by searching a plurality of defect management areas for a currently active defect management area in which the latest defect management information is recorded. If there is no unused defect management area in which defect management information can be alternatively recorded in lieu of the currently active defect management area, recording operation is limited.

A resolution heightening circuit comprises a modulation information generating circuit that receives printing data supplied from a host printer control circuit to generate a pulse width modulation information signal on the basis of the printing data. The modulation information generating circuit uses a reference template of four lines by three dots to increase the number of dots for a line at a printing unit. A modulation circuit is connected to the modulation information generating circuit and the printing unit and produces modulated driving pulses in response to the pulse width modulation information signal to supply the modulated driving pulses to the printing unit.

In a control method for image data including binary image data and multilevel image data, line information is attached to line print data for each of lines forming the image data and then the line information and the line print data are stored for each line in a memory. The line information is used to determine whether a data block included in the line print data is one of a binary image data block and a multilevel image data block. The binary image data block and the multilevel image data block for each line are processed according to the line information so as to produce a printed image of the image data.

The present invention provides a delay clock generator where a plurality of stable delay clocks can be generated and digitizing is easy. The delay clock generator comprises first to nth (n: integer not less than 2) delay circuits (11 to 1n) connected in cascade connection for delaying the basic clock (KO) in sequence, a phase comparator (21) for comparing phase of a delay clock from the nth delay circuit (1n) with that of the basic clock, and a delay control circuit (31) for generating a delay control value to make the phase of the delay clock from the nth delay circuit synchronize with that of the basic clock based on a phase comparison result, and for controlling delay amounts of the first to nth delay circuits respectively by the delay control value. In the present invention, a voltage control type oscillator is not used, and since delay amounts of the first to nth delay circuits are controlled by the delay control value generated based on the phase comparison result, the delay clock generator can be constituted wholly by digital circuits and moreover can generate stable delay clocks.

An intake device for an engine including the first intake valve located at the downstream end of the first intake passage that is connected to the primary carburetor. A second intake valve is located at the downstream end of the second intake passage that is connected to the secondary carburetor in a cylinder. Both intake passages are connected to each other through a pathway situated in the middle of said intake passages. A check valve located in said pathway allows flow from the first intake passage to the second intake passage. In accordance with a second embodiment, the primary and secondary carburetors are configured so that operation of the secondary carburetor is a function of negative pressure in the primary system to remain closed under minimal load conditions.
