Abstract: A leak tester of the present disclosure includes: an air pump for supplying air into the endoscope device; a pressure sensor that detects a pressure inside the endoscope device, and a control unit that controls operation of the air pump and the pressure sensor. The control unit executes: a first process of judging whether an internal pressure of the endoscope device has dropped by a first pressure value within a first time span after start of a wet test; a second process of judging whether the internal pressure has further dropped by a second pressure value different from the first pressure value within a second time span different from the first time span in a case where the internal pressure has dropped by the first pressure value in the first process; and a process of judging pass or fail in the wet test.

Abstract: A method and system for controlling the downloading of information to a computer. Depending upon the characteristics of a storage drive and/or the data which is to be downloaded, the data may be downloaded to a recordable storage medium without first storing the data to a hard disk drive. Alternatively, the data may be stored on a hard disk drive when it is downloaded.

Abstract: When a program is activated, data recorded in a predetermined sector is reproduced by an error correction. When no reproduction error occurs, the data in the predetermined sector is reproduced without conducting the error correction. When reproduced data are not a predetermined pattern, it is determined that write software illegally writes dummy data to the predetermined sector, instead of the predetermined pattern, and an optical disc where the program is activated is a copied optical disc. Accordingly, a process conducted by the program is terminated. Therefore, a process realizing original functions based on the program cannot be executed.

Abstract: When an optical recording device of a recording apparatus that is for executing optical recording of information on an optical disk records data on an optical disk, it obtains information by which the content of the data optically recorded can be guessed from the data recorded or from data of the recording apparatus. An image representing the obtained information by which the content of the data can be guessed is formed on a thermosensitive medium provided on the optical disk.

Abstract: A recoding apparatus includes an optical recording device that optically records information on an optical disk and an image forming apparatus that forms an image on a thermosensitive medium provided on the optical disk. When a moving image of a TV broadcast program is recorded on the optical disk by the optical recording device, it is possible to obtain information of TV broadcast such as a TV broadcast itself, an electronic program guide and the like, information held by the present recording apparatus or information relating to the program recorded by the optical recording device from information recorded on the optical disk. Then, the obtained information is image-formed on the thermosensitive medium provided on the optical disk by the image forming device.

Abstract: An information recording medium includes a pre-stamped region formed by pre-stamping a region from the start of the data region of the information recording medium. The pre-stamped region records information indicating that the information recording medium is a hybrid recording medium formed of a recorded region and an unrecorded region and information indicating that a sector in the pre-stamped region is pre-stamped. The information recording medium is formed based on a recordable recording medium.

Abstract: A reading unit reads first data blocks among the data blocks stored in an information storage medium according to the information specified by a mother system. A buffering unit temporarily stores the first data blocks read by the reading unit. A transferring unit transfers the first data blocks temporarily stored by the buffering unit to the mother system. A advancing unit causes the reading unit to read in advance second data blocks subsequent to the first data blocks in the information storage medium, the unit then causing the buffer unit to store the second data blocks. A controlling unit controls the advancing unit appropriately according to the information specified by the mother system.

Abstract: A method for controlling an optical disk apparatus when writing information into a defective sector, by storing a management table for alternate process in a memory for control, and by writing the management table into a storage medium. When a writing operation is abnormally ended in an anomalous state and when the alternate process is consecutively repeated for a defective sector, an upper limit of times of alternate process is set. When the number of alternate processes repeated reaches a preset number, the writing is suspended. Updating of the management table for alternate process may be inhibited.
