Title: Recording area detecting device, recording and reproducing device, and sector detecting method
Inventor: NAGATA MASAYOSHI
IPC: G11B7/005
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To always accurately detect address information of a recording area without erroneous detection, by coding address information of the next estimated recording area, generating estimated address data accordingly and making comparison between digital data of the next recording area and the estimated address data in all bits. SOLUTION: An estimated ID value A estimated for every sector is compared with an actual read-out ID value A' in all bits by an MO disk drive device 30 to recognize the correctness of the sector concerned upon coincidence of the all bits. Consequently, erroneous detection of a sector is prevented to eliminate malfunction even when an erroneous data comprising a interdictory data pattern due to eccentricity of an MO disk 32 and an external factor such as noise at the time of reproducing, etc., is read out. Thus, the data can be controlled to be recorded and read out by a control part 44 based on a comparison result in the MO disk drive device 30.

Title: Camera-shake correction camera
Inventor: AMANUMA TATSUO
IPC: G03B17/00
Filed: 1994-02-03
Abstract: PURPOSE:To avoid trouble that camera-shake detecting accuracy is lowered because battery voltage is low by deciding before starting the detection of camera-shake whether or not the battery voltage is equal to or above a specified value and starting the detection of the camera-shake only when it is equal to or above the specified value. CONSTITUTION:This camera is provided with an operating member outputting a photographing preparation instructing signal and a photographing start instructing signal, a battery which supplies power to the respective parts of the camera, camera- shake detection means 21 and 22 for detecting the camera-shake caused in the camera, and a camera-shake correction means 102 for performing correction that the detected camera shake is negated at least in the midst of exposure. When the photographing preparation instructing signal is inputted from the operating member, a decision means 2 decides whether or not the battery voltage is equal to or above the specified value. Only in the case of deciding that the battery voltage is equal to or above the specified value, detection by the detection means 21 and 22 is started by a control means 2. Furthermore, since the battery voltage is measured by connecting an electric load in the case of the measurement thereof, the accuracy of the measured battery voltage is improved.

Title: Stepless speed changing device
Inventor: ITOU TAKEO
IPC: F16H13/04
Filed: 1980-02-02
Abstract: PURPOSE: To obtain the stepless speed changing device at low cost capable of rotating normally and reversely by constituting a driven disc having an axis extending rectangularly with respect to the axis of a driving disc in a manner freely movable in the axial direction, and bringing the driven disc into contact with the end face of the driving disc through a transmission roller.  
     CONSTITUTION: In a state illustrated in the drawings where a transmission roller 12 is in spot contact with a driving disc 4 on the axis thereof, even when an input shaft 1 rotates in a predetermined direction, the rotational moment is zero. Therefore, a driving force is not transmitted to the transmission roller 12, and hence a driven rotary body 10 and an output shaft 6 are placed in a standstill state. Then, when a handle 18 is manipulated, and a moving body 16, that is, the transmission roller 12 and driven rotary body 10 are rotated in one direction through an operating rod 17, a driving force is acted on the contact point of the driving disc 4 in the transmission roller 12, which is thereby rotated. Accordingly, the driven rotary body 10 is rotated, and the output shaft 6 is rotated in the same direction. When the handle 18 is reversely manipulated, and the transmission roller 12 is brought into contact with the position reverse to the above described case, the output shaft 6 is reversely rotated.
