IPC: G11B7/24082
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To determine a track stably by detecting the extent of correlation to the address information contained in the outputs of reflected light of a main spot scanning on a track and first and second side spots and determining the track depending on the extent of correlation thereby suppressing the effect of radial skew of a disc.

Title: Semiconductor laser coupler
Inventor: KUMAZAWA TETSUO
IPC: G02B6/42
Filed: 1987-05-11
Abstract: PURPOSE:To readjust the displacement of an optical axis due to the release of a remaining strain or a clamping force and to obtain a high optical output coupling efficiency by forming a stepped part at a part of a supporting member for holding a ferrule attached with an optical fiber. CONSTITUTION:When an assembling jig is removed, an optical axis displacement occurs. Since the displacement of the optical axis forms a place to be easily deformed at an angle and in one direction at part of a supporting member 9, i.e., a stepped part 10 to be deformed by tension or bending, when part of the member 9 is bent by holding, it can be bent in a direction for increasing an optical output to be adjusted at its optical axis. A small permanent deformation occurs by pulling or compressing the member 9 integral with a ferrule 11 to adjust the positional displacement in an optical axis direction. Thus, the displacement of the optical axis due to the release of the residual strain or clamping force can be readjusted to obtain a high optical output coupling efficiency.

Filed: 1991-05-17
Abstract: PURPOSE:To obtain the image of the part near to the surface of an object to be inspected without superposing the contrast of the surface of the uneven shape of the object to be inspected. CONSTITUTION:Ultrasonic waves are allowed to be incident to the measuring point P of an object 6 to be inspected from an ultrasonic transmitter-receiver 8 and the reflected waves to the incident waves are received by a phase conjugate mirror 18. The phase conjugate mirror 18 allows the phase conjugate waves to the received reflected waves to be incident to the measuring point P of the object 6 to be inspected. At this time, the strain of the wave front of the reflected waves caused by the surface uneven shape of the object 6 to be inspected is set off by the time reversal properties of the phase conjugate waves. The reflected waves from the measuring point P to the phase conjugate waves arm received by the transmitter-receiver 8 and converted to the electric signal corresponding to the intensity thereof. This electric signal output is different according to the acoustic impedance of the measuring point P. Therefore, by scanning the measuring point P by an XY scanner 20 and plotting the reflected wave output at each scanning point on a display 16, the image of the part near to the surface of the object 6 to be inspected is formed.

Abstract: PURPOSE:To provide a method of controlling the operation of air-conditioner, which is capable of stabilizing the indoor temperature quickly to a set temperature without excessively adjusting the opening degree of a hot-water flow rate regulating valve. CONSTITUTION:An indoor temperature Tr upon starting room heating operation is compared with a set temperature Ts and when Tr<=Ts, the opening degree of a hot-water flow rate regulating valve is set at a first initial period opening degree set value thetas1.
