Title: Thin film magnetic head
Inventor: YAMADA KAZUHIKO
IPC: G11B5/31
Filed: 1988-08-30
Abstract: PURPOSE:To increase the thickness of a coil and to suppress the increase in the resistance value of the coil by the increased number of windings by forming the coil of a laminate formed with the films of a plating substrate, Cu plating layer and carbon layer in this order. CONSTITUTION:The ion etching rate of carbon in a gaseous Ar atmosphere is extremely low. Since the carbon layer 5 is laminated on the Cu plating layer 3, the carbon layer 5 of the low ion etching rate protects the surface of the Cu plating layer 3 even if the front surface of the coil is ion etched over a long period of time at the time of ion etching in the plating substrate removing stage during the coil forming process; therefore, the decrease of the coil voltage does not arise. The increase in the resistance value of the coil by the increased thickness of the coil and the increased number of the windings is suppressed.

Filed: 1992-08-17
Abstract: PURPOSE:To provide a rice boiler by which rice is boiled with good taste in a fixed time of heating independent of the amount of boiled rice, by a method wherein the amount of heating is regulated so that the change of temperature detected through an electromagnetic induction type inner vessel can be matched to an ideal temperature curve for boiling rice, which curve is previously stored. CONSTITUTION:A fixed amount of water 6 and rice 7 are put into an inner vessel 2 within a rice boiler body 1 and rice boiling begins to be started. A direct current produced by rectifying a commercial power 8 with a rectifier 9 is turned off and on by a switching element 13 and thus a microwave is produced. The microwave is applied to an induction-heating coil 12 and the inner vessel 2 is dielectrically heated. A means 16 detects a temperature by a thermal sensor 4, a means 24 detects the rate of a temperature rise and a means 25 determines the amount of boiled rice. On the other hand, a comparison between output from a storing means 22 for the rate of the temperature rise corresponding to toughness preset by a toughness-presetting means 21 and the rate thereof detected by the means 24 is made by a comparator 23. A presetting means 27 for the amount of heating controls the amount of heating for the heating coil 12, by presetting the amount of electric current on the basis of the amount of boiled rice and a temperature difference, and by regulating the duty ratio of the switching element 13 through an output-regulating means 15. In this way, boiled rice with favorite toughness is boiled approximately in a fixed time independent of the amount of boiled rice.

Abstract: PURPOSE:To improve the rigidity of the captioned actuator, by dividing the oil chamber of the actuator into two chambers with a common piston and connecting said chambers to passages at the front and rear part of a pump respectively. CONSTITUTION:A piston 46 is slidably mounted inside the cylinder case 41 of an actuator 40, and an oil chamber 45 is divided into chambers 45A, 45B wherein the chamber 45A is connected to a first branch oil passage 53A and the chamber 45B to a second branch oil passage 53B. Therefore, the pressure in a circuit is, at the normal condition, maintained to be equal to an accumulator set pressure and, in case that one side of the actuator is pressurized over an initial pressure, the other side thereof is reduced under the initial pressure by about the same amount with the pressure balance in the accumulator 40 so as to make larger the effective differential pressure. Therefore, the both sides of the actuator are opposed to a load respectively so that it is possible to improve the rigidity of the actuator.
