Title: Production of recording medium
Inventor: SAKAMOTO SUSUMU
IPC: G11B7/26
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To control the film thickness of a dyestuff layer to be applied on a substrate and to form the dyestuff layer of a desired film thickness at a low cost by dissolving an org. dyestuff into a solvent mixture prepd. by mixing >=2 kinds of solvents varying in supplying. sp. gr., and changing the sp. gr. of a dyestuff soln. SOLUTION: The cyanine dyestuff is mainly used as the dyestuff for recording and is thermally deformed by absorption of a laser beam. When a diacetone alcohol having, for example, excellent solubility is used as the main solvent for the cyanine dyestuff, the b.p. of the solvent mixture is lowered by incorporating an isopropyl alcohol, etc., having the compatibility with the main solvent and having the low b.p. as the auxiliary solvent into the main solvent in a volume of about 5 to 10% of the main solvent. A spin coating method is adopted for formation of the dyestuff layer on the substrate. At this time, the dyestuff soln. mixture is lighter in the sp. gr. than the dyestuff soln. of the main solvent alone and the control of the film thickness of the dyestuff layer formed on the substrate is made possible by controlling the amt. of the auxiliary solvent.  The amt. of splashing is decreased and the amt. of the costly dyestuff for recording may be reduced.

Title: C-mos output circuit
Inventor: SASAKI TAKESHI
IPC: H01L27/092
Filed: 1986-07-31
Abstract: PURPOSE:To prevent an output circuit from being broken due to static electricity, by making the connections of zenor diodes between sources and drains of MOS-type field effect transistors(FET). CONSTITUTION:Both drains of MOS-type FETs 2 and 3 are connected with an output terminal 4 through a resistor R1. A cathode of a zenor diode ZD1 is connected with a source of the MOS-type FET 2 (C-MOS's drain), and an anode of a zenor diode ZD2 is connected with a source of the MOS-type FET 3. Besides, the anode of the zenor diode ZD1 and the cathode of the zenor diode ZD2 are connected together at a connection point between the resistor R1 and the output terminal 4. Even if large positive and negative noises are caused by static electricity on the output terminal 4, they can be absorbed, for example, by characteristics of the zenor diodes ZD1 and ZD2 having breakdown voltages smaller than gate-withstand voltage, and then current can be limited by the resistor R1. Hence, the C-MOS output circuit can be protected against an electrostatic stress.

Abstract: PURPOSE:To realize a device, easy to manufacture, inexpensive, capable of pressure and acceleration detection and of temperature compensation, by a method wherein a magnetic bias-applying magnet is installed in line with a magnetoresistance stripe with its resistance changing under physical stress and resistance values are detected representing normal and displaced conditions. CONSTITUTION:On a protective film 33, through the intermediary of a spacer 36, a magnetic 34 is installed, which applies a bias magnetic field to magnetoresistance stripes 31a and 31b, with a prescribed distance from the protective film 33. The magnet 34 is a magnet magnetized in an oblique direction with the resultant N and S poles positioned askew, and is located in parallel with the surfaces of the magnetoresistance stripes 31a and 31b. When there is a change of DELTARb in the resistance Rb of the magnetoresistance stripe 31b owing to displacement of a thin film 32a of a substrate 32 under physical stress, there is an output Vout=Ra.Vcc/(Ra+Rb-DELTARb). Accordingly, the change DELTARb in the resistance value may be known by detecting the output Vout, which may be used to determine the quantity of displacement.

IPC: G01N27/409
Filed: 1994-07-08
Abstract: PURPOSE:To quickly detect the oxygen gas concentration with high accuracy from a specimen gas having a low oxygen concentration by introducing a buffer gas behind a specimen gas detecting electrode on a specimen gas passage, preventing the inflow of the outside gas, and discharging the residual gas. CONSTITUTION:A specimen gas detecting electrode 2 and a reference gas electrode 3 are fitted to a cylindrical oxygen gas solid electrolyte 1, for example, and a buffer gas is introduced to the downstream from a buffer gas guide pipe 4. When the specimen gas flows in and reaches the detecting electrode 2, electromotive force is generated from the difference of the oxygen partial pressure between the reference gas and specimen gas, and the current value is measured to detect the oxygen gas concentration. The specimen gas passing through the detecting electrode 2 is mixed with the buffer gas introduced from the buffer gas guide pipe 4 and discharged into the outside air. The outside gas is prevented from flowing back to cause an error in the detected value. The residual gas is discharged before measurement to accelerate measurement. The buffer gas having a oxygen gas concentration lower than that of the specimen gas is used.
