Title: Defect processing method for optical disk, and optical disk device
Inventor: OHATA HIROYUKI
IPC: G11B23/00
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To secure an alternation area for relieving a defective sector generated due to a dust, stain, etc., stuck at the time of taking out a disk, by additionally setting an alternation area for relieving defective sector on the disk once taken out from a cartridge. SOLUTION: Possibility of resetting the alternation area is judged by a judging part 7 for the resetting of alternation area, in accordance with a signal for finish of take-out outputted from a detection part 6 for finish of the disk taking out which detects whether or not an optical disk medium is taken out from the cartridge, and with the output of a recognization part 9 of information recording state wherein the position of recording information or the size is detected. When an instruction to reconstruct the alternation area is outputted by the judging part 7, the alternation area is reconstructed by an alternation area re-constructing control part 10 to produce the alternation area managing information and send it to an information recording/reproducing head 8.  Thus, when the information is recorded on the medium ever taken out from the cartridge, the reliability is improved by means of increasing the alternation area, and simultaneously the recording area is efficiently usable.

Title: Ignition timing control device for internal-combustion engine
Inventor: HARAGUCHI HIROSHI
IPC: F02P5/153
Filed: 1982-03-08
Abstract: PURPOSE:To prevent the fumble of acceleration by judging the acceleration state based on the ignition delay state to increase the ignition advance speed and by judging that a stationary state is attained based on the subsequent ignition advance state and knock sensor information to decrease the ignition advance speed. CONSTITUTION:The total ignition delay quantity with successive ignition delays and no ignition advance during a stationary state is small, but large during an acceleration state, thereby the stationary state and the acceleration state are discriminated by a control circuit 8, and the ignition advance speed is increased during the acceleration state. The target value of the ignition advance is made the basic ignition time based on the base map of a microcomputer, but the knock limit ignition time of the stationary state passes before the target ignition time is attained, thus generating a knock signal 7. Therefore, if the ignition advance speed is decreased when a knock occurs or a predetermined number of knocks occur, a stable control condition under the stationary state can be smoothly attained. It is further effective to delay the starting time to increase the ignition advance speed a little. Accordingly, the fumble of acceleration can be prevented.

Abstract: PURPOSE:To obtain a photosensitive material having high sharpness, high sensitivity, and good graininess by regulating the silver density of at least one silver halide emulsion layer to a specified value and incorporating silver halide emulsion having a fog center into the layer or into the adjacent layer. CONSTITUTION:Photosensitive silver halide emulsion layers are formed on a base body and the silver density (d) of at least one silver halide emulsion layer is regulated to >=5.0X10<-1>g/cm<3>. Said density (d) is preferred to be about 2.0g/cm<3> from the view point of fogging, wherein the silver density (d) is expressed by N/V, wherein N is the amt. of silver (g) (expressed in terms of metallic Ag) in the photosensitive silver halide emulsion layer; V is the volume (cm<3>) of the photosensitive silver halide emulsion layer. Silver halide emulsion having fog centers is incorporated in the layer or in the adjacent layer.
