Inventor: FUJINAMI YASUSHI
IPC: G11B7/005
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To enable the securing of compatibility by recording data to a recording medium, judging whether the data are continuously reproducable or not with respect to already recorded data and executing processings concerning the continuous reproduction of the data corresponding to the result. SOLUTION: After the video signal inputted from an input terminal P3 and the audio signal inputted from an input terminal P4 are encoded in an encoder 10, the encoded data are transmitted to a buffer for write channel 11. The data read out from the buffer 11 are inputted to an ECC circuit 4 via a switch 5 and after the data are added with error correcting codes in the circuit, the signal outputted from an RF and modulation/demodulation circuit 3 is written on an optical disk 1 with an optical head 2. An address detecting circuit 12 detects address information of a track performing a recording to the disk 1 or performing a reproduction from the disk 1 and a CPU 21 finely adjusts the position of the optical head 2 based on the detection result of the address detecting circuit 12.

Abstract: PURPOSE:To cool a disk brake by utilizing an oil damper by connecting an oil pressure generating chamber and an oil reservoir chamber of the oil damper to the inlet and outlet of the cooling oil passage of a brake caliper respectively via a variable orifice means. CONSTITUTION:When a front fork F is shrunk during the travel of a vehicle, oil pressure is generated in a lower oil pressure generating chamber 29 to open a check valve 39, oil flows through the oil passage of a brake caliper C and a discharge pipe 38, and the brake caliper C is cooled. On the other hand, when the front fork F is extended, the check valve 39 is closed, and the counterflow of oil into the lower oil pressure generating chamber 29 is prevented. A check valve 28 in the front fork F is opened, thus the oil in the lower oil pressure generating chamber 29 flows into an upper oil pressure generating chamber 30, and a damping action is performed by the compressive force of a coil spring 27 and the passage resistance of the check valve 28. In this case, the damping action of an oil damper Da and the cooling efficiency of the brake caliper C are adjusted by a variable orifice means 40.

Abstract: PURPOSE:To obtain an optical fiber communication device whose signal transfer time is highly stable against a temperature variation by setting a dependability to a temperature of an oscillation wavelength of a light source and a temperature dependability of a signal transfer time of an optical fiber, to a specified relation. CONSTITUTION:An optical information of a light source 2, which is sent out by an optical transmitting device 1 is transferred to a receiving device 4 through an optical fiber 3. A temperature variation DELTAT of the circumference of this optical fiber 3 is detected by a temperature detecting device 6, and given to a temperature control device 7. This temperature control device 7 gives a temperature variation KDELTAT proportional to a temperature variation DELTAT to the light source 2, and controls a temperature of the light source 2.

Abstract: PURPOSE:To detect a rotary direction and the number of rotations by simple constitution by moving the leading end part of a movable piece to the surface or rear of a rotary plate when said leading end part is pushed by the large diameter part of the rotary plate to open and close a contact. CONSTITUTION:When a rotary plate 1 is rotated in a counterclockwise direction, the inclined leading end part 21 of a movable piece 2 impinges against the large diameter part 12 of the rotary plate 1 and the contact 22 of the movable piece 2 comes into contact with the contact 31 of a fixed piece 3 and both contacts become a continuity state. When the rotary plate 1 is reversely rotated in the clockwise direction, the leading end part 21 is pushed down and a contact 23 comes into contact with the contact 41 of a fixed piece 4 and both contacts become a continuity state. When the rotary plate 1 makes one revolution and the small diameter part 11 thereof again comes to the place of the leading end part 21, them contacts in the continuity state open. Therefore, by connecting the movable piece 2 and the fixed pieces 3, 4 to an appropriate detection circuit part, the rotary direction and number of rotations of a rotary shaft 5 can be detected by a simple structure.
