Title: Cmos constant voltage circuit
Inventor: NISHIKUBO YASUHIKO
IPC: G05F3/26
Filed: 1981-03-06
Abstract: PURPOSE:To obtain superior temperature characteristics by obtaining reference voltage by a single current mirror type reference voltage circuit, and using a difference between those reference voltages as the output voltage of a constant voltage circuit. CONSTITUTION:In a single current mirror type reference voltage circuit 3a, a reference voltage VR'G3 is developed at the drain output of an NMOS transistor (TR) 106, and a reference voltage VR'G4 is developed at the drain output of a PMOSTR301. A potential difference VR'G5 between those reference voltages VR'G3 and VR'G4 is nearly proportional to the sum of the threshold voltages of an NMOSTR105 and a PMOSTR302. Variation in threshold voltage depends mainly upon variation in temperature, and both the reference voltages are extracted from a single reference voltage, so their temperature coefficients are nearly equal. Therefore, the difference in reference voltage has excellent temperature characteristics. It is passed through a difference amplifying circuit 3b and a voltage follower circuit 3c to obtain a necessary value, developing a new reference voltage.

Title: Protective film and magnetic recording medium using the protective film
Inventor: SASAOKA YASUSHI
IPC: C23C16/26
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To realize sufficient durability and corrosion resistance even if a film is made thin by providing a protective film comprising a fine grain having equal to or below a specific particle diameter. SOLUTION: Since the grain constituting the protective film has a small particle diameter of <=2 nm, the bonding power between the grains is increased and the omission of grains due to the sliding of a head at the time of CSS (contact start and stop) hardly occurs to improve the durability. And the gap of grain boundary is eliminated since the grains are rigidly arranged each other and the magnetic layer is completely shut out from the atmosphere to keep corrosion resistance excellent under a high temp. and high humidity condition. The film forming method is not limited if the film is formed to ham <=2 nm thickness and the film forming by a sputtering method, a chemical film forming method and the like is possible.
