Title: Recording control method for optical disk recording/ reproducing device
Inventor: HATTORI KATSUMI
IPC: G11B7/125
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To avoid abnormal recording operation of a disk by checking disk characteristics and executing operation correspondent to the disk characteristics in accordance with the checking command outputted subsequently from the host. SOLUTION: When a disk 1 is loaded on a driving device, the system control circuit 10 performs a checking operation of the characteristics, such as the discrimination of a recording speed performance by a discrimination code recorded on the disk 1 and the discrimination of temperature for recording suitability by detection data from a temperature detecting element, and carries out a setting operation of a laser output. Before the start of the recording operation, a checking command is outputted from a computer device 9. If a recording operation is possible at a recording speed instructed by the device 9, the operation is executed at such speed. If the recording operation is impossible at such command speed, the recording speed to be instructed is lowered by one rank and, if the operation is possible at the altered speed, it is executed at such command speed.

Title: Receiver in digital audio broadcast
Inventor: NEMOTO HIROYUKI
IPC: H04L27/22
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To output a DAB broadcast audio signal in a short time by reducing a time required for transmission mode identification processing. SOLUTION: A 1st transmission mode decision section 81 takes notice of it that a digital audio broadcast(DAB) frame period depends on a transmission mode to generate a null window for a minimum frame period among a plurality of frame periods of transmission modes and identified a transmission mode of a DAB broadcast station, based on a ratio of number (a) of generated null windows to number (b) of detected null signals when the null window is being generated. Furthermore, in the case that two transmission modes with the same frame period exist and the 1st transmission mode identification section cannot identify the transmission mode, a 2nd transmission mode decision section 82 calculates the correlation between a known phase reference symbol and a demodulation result by a discrete Fourier transformation(DFT) under the assumption that the DAB broadcast radio wave is sent in one transmission mode and discriminates it that the transmission mode is the one transmission mode, when the correlation is a set level or over and the transmission mode is the other transmission mode, when the correlation is less than the set level.

IPC: G06F13/28
Filed: 1994-11-10
Abstract: PURPOSE: To enable high-speed transferring without completely stopping CPU, corresponding to a wide-range transfer request of a DMA device. CONSTITUTION: A DMA controller 102 obtains the usage right of busses 105, 106 and 107 at the time of a DMA request and starts transferring. In this case, a transfer interval timer 211 is started, transfer is interrupted when the prescribed time elapses and returns control to CPU. During transfer, transferred data quantity is counted by a temporary counter 210. Transfer speed is calculated by data quantity and passage time, time according to the transfer speed is set in the timer 211 again and succeeding transfer is executed. Thus, since control is returned to CPU at every prescribed time, a system where a processing by CPU is not completely stopped without slowing down DMA speed more than necessity is constituted.

Filed: 1989-10-24
Abstract: PURPOSE:To prevent a friction pad from being deformed by installing a pad reinforcing member with higher rigidity than the friction pad, coming into close contact with the opposite surface to a pressure contact surface of the friction pad to a sheet feed roller. CONSTITUTION:A document 7 is placed on a guide plate 4 to rotate a sheet feed roller 1, however, even when the document 7 is inserted up to a nip position between a friction pad 2 and the sheet feed roller 1, the part near mid part 2a of the friction pad 2 is prevented from being elastically deformed with a pad reinforcing member 12. Therefore, even when sheet feed is started by the sheet feed roller 1, the friction pad 2 is not elastically deformed, so it is possible to make the sheet force of the sheet feed roller 1 work upon the document 7 efficiently. It is, thus possible to prevent sheet feed failure of the document 7 and delayed timing of sheet feed.
