Title: Tracking error detecting circuit
Inventor: SASAKI YASUO
IPC: G11B7/09
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To provide such a tracking error detecting circuit that an offset value to be generated is properly calculated by determining a parameter optimum to a tracking condition based on characteristics of an individual recording medium and a recorder and the offset value can be canceled. SOLUTION: In the wobble push-pull circuit 201 provided in an RF-IC (an integrated circuit in which circuits performing processings of RF signals are integrated), an offset value is made to be generated in a tracking error signal by moving an objective lens. A proper tracking servo is applied by canceling this offset value while inputting a forcive offset canceling signal KPPO to a subtractor 223. At this time, the offset cancel value CSL detected by offset value detecting circuits 211-218 is observed and the coefficient Kw of a coefficient multiplier 217 is adjusted so that this value becomes a proper value.

Title: Pressure sensor
IPC: G01L9/04
Filed: 1992-03-19
Abstract: PURPOSE:To obtain a pressure sensor which can prevent the flowing out of an introduced fluid when its sensor chip is broken. CONSTITUTION:A circuit board 5 and sensor chip 6 are put in a void space formed between a body 1 equipped with a fluid pressure introducing port 2 and cover 8. The chip 6 is faced to the port 2. A small-diameter section 3 is formed in the port 2. A plug member 4 having a shape which can block the section 3 is passed through the section 3 in a state where the member 4 can make reciprocating motions. The space between the chip 6 and member is filled up with a gel-like pressure transmitting medium 7. When a pressure is introduced from the port 2, the pressure acts on the chip 6 through the member 4 and medium 7. In case the chip 6 is broken, the member 4 moves in the port 2 and blocks the section 3 due to the introduced pressure. Therefore, flowing out of the fluid introduced from the port 2 is prevented.
