Title: Manufacture of magnetic film
Inventor: DOUJIMA MASAJI
IPC: G11B5/31
Filed: 1992-12-14
Abstract: PURPOSE:To improve the soft-magnetic characteristic and saturated magnetic flux density of a magnetic film by specifying the ratio of the partial pressure of an N2 gas to the pressure of a mixed gas of an Ar gas and the N2 gas at the time of forming an Fe-Si-N film in the mixed gas by using a sputtering method. CONSTITUTION:An Fe-Si-N magnetic film is manufactured by setting the partial pressure of an N2 gas to the pressure of an Ar+N2 gas at >=25% and <=45% at the time of forming the magnetic film in the Ar+N2 gas atmosphere. The magnetic film is formed by using a sputtering method, such as the ion-beam sputtering method, high-frequency sputtering method, etc. The target used for forming the magnetic film can be an Fe-Si alloy target having a desired composition, individual pellet-like Fe and Si target, or a composite target formed by arranging Si pellets on an Fe target. The degree of vacuum to be reached at the time of using, for example, an ion-beam sputtering device is adjusted to about <=2.7X10<-4>Pa. Therefore, a high-purity magnetic film having strong adhesion can be formed by maintaining the substrate temperature at a low level.

Abstract: PURPOSE:To automatically discriminate whether the added water weight is proper or not, to prevent water from being supplied excessively and to improve the eating taste by constituting the controller so that a weight detecting means detects weight of a pot part, a moisture value measuring means measures a moisture value of rice, and a discriminating means discriminates whether the added water weight is proper or not by inputting the moisture value from a moisture value input means and the detected weight. CONSTITUTION:When rice to be cooked is supplied to an inner pot 2, it is pressurized against tension of a spring 6, and weight is measured by a weight meter 5. Also, water of uncooked rice is measured by a moisture meter 16. Subsequently, with regard to weight of soaked rice supplied to the inner pot 2, a CPU 18 judges that the water quantity is excessive and outputs a signal to an informing means through an interface 23. By this signal, water is dipped out to the outside of a rice cooker, for instance, by a glass. Next, when a rice cooking switch 13 is turned on after setting the time by a time setting part, the CPU 18 which inputs these signals through an interface 20 outputs a heating command signal to a heater 7 through the interface 23 and heats the inner pot 2 and starts a rice cooking work. Thereafter, at the time of reaching the set time, the CPU stops the output of the heating command signal to the heater 7 through the interface 23 and the rice cooking work is ended.

Abstract: PURPOSE:To make equal pitch loading easy by making an indicator provided at an article loading position operate when a distance detected by a conveyor moving distance detecting means provided on a conveyer reaches a set value, in the case of device stated in the title in an assembling line for an automobile. CONSTITUTION:In every moment when a chain conveyer 1 loaded with frame 2a progresses by a constant distance d1, three proximity sensors 51-53 respectively generate pulses. Distance of movement of each frame 2a is gained by counting these pulses with a control board 6. Meanwhile, an appointed pitch is set by an operation board 7. The control board 6 compares the set value of pitch with the detected distance of movement and lights an indicator 4 at the time of movement across a distance corresponding to the appointed pitch. As this indicator 4 moves together with the conveyer 1, the next frame 2b is placed on the conveyer at the position of the lighted indicator 4. Equal pitch loading can be done by this constitution.
