Title: Optical disk device
Inventor: INOUE RIYUUICHI
IPC: G11B7/004
Filed: 1983-02-24
Abstract: PURPOSE:To prevent data on a medium from being destroyed even when the medium is loaded erroneously to a disk device by attaining the reproduction of the front side of an optical disk medium for both sides access by an optical disk device for one side access and reproduction of both front and back sides of an optical disk medium for one side access by a head for front side access of an optical disk for both sides access. CONSTITUTION:A data read from a medium is attained for synchronism between the clock and the data by a demodulating circuit, a serial data is converted into a byte parallel data by a serial-parallel converting circuit 4, and the data is received by a microprocessor 2 through a data transfer control circuit. The microprocessor stores a sector number reproduced at first, and the number is compared with a sector number reproduced next, and when the number is incremented by 1, it is discriminated that the medium is an optical disk medium for one side access or the front side of an optical disk medium for both sides access is read by an optical head. In applying an example of this execution of invention to a one side access optical disk device, when the back side of the optical disk medium for both sides access is reproduced, it is discriminated that the sector numbers are not pre-grouped in the ascending order, and a failure is reported to a high-order device or the failure is informed because the device cannot be operated.

Title: Object detector
Inventor: KUBO KAZUHIRO
IPC: G01V1/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a photo-detector independent of that for object detection and to reduce cost, by identifying a detection abnormal state wherein a detection abnormal judgement part cannot detect an object in normal manner based on photo-detection state of a photo-detecting device. SOLUTION: A pulse laser light elected from a light-emission device 20 is reflected on a rotatable mirror 31, then passes through a cylindrical lens 33, and is projected outside through a window 60. If an object exists in the direction where the laser light is projected, the laser light is reflected. The reflected laser light is photo-detected with a photo-diode 42, and a photo-detection signal is transmitted from the photo-diode 42 to a control part 11. Meanwhile, at a detection abnormality judging part 13, judgement is done for detection abnormality based on the photo-detection signal from the control part 11.  In short, the detection abnormality judging part 13 divides a to-be-detected region into plural sub-regions, and monitors how the reflected laser light is photo-detected in the sub-region, for identifying detection abnormality state where an object cannot be detected in normal manner.

Title: Printer output system
Inventor: TAKATSUKASA NAOTAKE
IPC: B41J29/48
Filed: 1990-02-09
Abstract: PURPOSE:To dispense with the monitoring or 'no sheet supply' and enable a large amount of data to be printed out without printing interruption halfway through operation by detecting the remaining amount of the sheets to be fed to a printer using a computer, and indicating 'no sheet supply' without printing out data, if the detected value is lower than the required number of sheets for an output from a printer. CONSTITUTION:A sensor 4 which detects the remaining amount of the sheets is provided on a sheet case 3. If a request for an output to a printer 2 generates, a computer 1 loads an output from the sensor 4 to detect a remaining sheet amount. At the same time, the computer 1 calculates the number of sheets required for a file as a purpose of printer output, and causes a display part 5 to indicate a remaining sheet shortage without allowing data to be printed out, if such a shortage occurs. Then the computer prompts an operator to interpret whether an output from a printer should be permitted. Thus the monitoring of 'no sheet supply' is no longer required and even a large amount of data can be printed out without interrupting printing halfway through operation.

IPC: G06F17/30
Filed: 1987-02-13
Abstract: PURPOSE:To improve efficiency in retrieving a model sentence by automatically executing the division into a word in a short unit and executing a retrieval by using only index file even when a key word is not the entry of the index file. CONSTITUTION:Even if how to divide the key word is not known, the division into the word in a short unit is automatically executed in the same process as the broaching of the index file 7 and the retrieval is executed by using only the index file 7 without directly accessing a model sentence data file 8.
