Inventor: UNO KEISUKE
IPC: G01P15/02
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic amount sensor in which no output change occurs due to temperature change. SOLUTION: A plurality of protrusions 10b are formed on the inner bottom 10a of a resinous package 10, and a sensor chip 12 is disposed at the ends of the protrusions 10b.

Title: Photodetector
Inventor: MATSUI TSUTOMU
IPC: G11B7/09
Filed: 1981-06-25
Abstract: PURPOSE:To simplify and miniaturize the constitution of a photodetector, by forming a photodetection pattern with 6 radial photodetecting elements obtained by dividing a photodetecting element into two parts centering on a vertical axis and then dividing the element into two parts centering on the axes which are shifted from the vertical axis left and right by 45 deg., respectively. CONSTITUTION:Photodetecting elements (a), (c), (d) and (f) having a 45 deg. angle respectively among 6 photodetecting elements forming a photodetecting pattern detect a light in the direction (y); while the elements (b) and (e) having a 90 deg. angle detect a light in the direction (x). Thus a focal error is detected. The detecting output of each photodetecting element is applied to adders Afy and Afx for detection of focal error or adders Atl and Atr for detection of tracking  error. The outputs are equal to each other between the adders Afy and Afx  when focusing is obtained. Thus a focal error signal delivered from a subtractor  Sf is set at zero. When a photodetecting spot is on a track, the outputs are  equal to each other between the adders Atl and Atr. Thus the tracking error  signal delivered from a subtractor St is set at zero.
