Title: Magnetic disk device
Inventor: MURANUSHI FUMITAKA
IPC: G11B21/12
Filed: 1993-06-24
Abstract: PURPOSE:To load and unload a magnetic head slider by making a part of the side of a slider supporting mechanism facing the surface of a magnetic disk retatively protruded to its back surface and generating force in the approaching direction to the surface of the magnetic disk by fluid force of airflow attend accomanying rotation of the disk. CONSTITUTION:A cross section of an inner tip part of a supporting mechanism 3 of the slider is made as shown in the figure. Because of a difference of flow speed between an airflow 101 flowing over the upper surface of the supporting mechanism 3 and an airflow 102 flowing over the lower surface (surface on the side facing the disk 2), the airflow 102 has a lower pressure than the airflow 101 so that pressing force is worked in the direction of an arrow 103. Consequently, the magnetic head slider is pressed against the magnetic disk 2, and the magnetic head slider pressed against the disk is floated above the disk 2 by positive pressure due to an air bearing effect, and hence the loading of the magnetic head slider is completed. When the revolving speed of the disk is dropped in order to stop the disk device, the pressing force 103 is reduced, and the magnetic head slider is separated from the disk and is unloaded.

Title: Nitrogen oxide controller
Inventor: ORIMOTO MANABU
IPC: F23C99/00
Filed: 1986-07-02
Abstract: PURPOSE:To reduce cost for power in a plant, by a method wherein draft is increased only when a kind of coal, whose combustion gas contains NOX of high concentration, is used and the draft is reduced in other cases, when various kinds of coal, provided with different natures, are burnt. CONSTITUTION:An airflow damper 14 for two-step combustion is closed and a burner air resister is opened by 50-60% from starting to 20% load while the damper 14 is opened by a NOX setter 25 upon throwing coal into a furnace. When the fuel ratio and nitrogen content of the coal are high and the NOX/ unburnt constituent thereof is large, the opening degree of a resister 30 is coped with the set value of NOX by bypassing by the damper 14 while chocking control is effected so as to reduce the unburnt constituents. When the fuel ratio and nitrogen content are low, the opening degree of the resister 30 is increased to reduce a draft and a burner is operated with the small opening degree of the damper 14. The generation of NOX is increased when a furnace temperature is increased upon increasing the load of the burner, therefore, oxygen is reduced by the burner and the opening degree of the damper 30 is increased to suppress the unburnt constituents by the supply of air. The setter 25 corrects the damper 14 through a bias device 31 for two-step combustion and an adder 32.

Filed: 1977-12-22
Abstract: PURPOSE:To highly accurately stabilize a watch by compensating the frequency fluctuations in the time reference signals which are generated as a result of the potential variations during the charge and discharge of a secondary battery. CONSTITUTION:When the discharge of a secondary battery 12 exceeds 30 % so that the battery potential is lowered to reduce the output signals of a voltage detecting circuit 12 to ''0'', an auxiliary frequency dividing circuit 4 is reset, and the time reference signals from an oscillating circuit 1 are subjected to frequency division through a transmission gate 2 by a frequency dividing circuit 5 thereby to display the time in a display unit 8. When the secondary battery 12 bigins to be charged by the optical irradiation upon a solar cell 9 to increase the output signals of the circuit 12 to ''1'', the auxiliary circuit 4 takes its frequency division starting condition so that a transmission gate 3 becomes conductive. Since the oscillatory frequency of the circuit 1 is subjected to the frequency division by the circuit 4 and then by the circuit 5, the frequency increment due to the rise in the voltage of the secondary battery is counted by the auxiliary circuit 4 so that accurate time reference signals can be generated at the output of the circuit 5.
