Title: Air spindle unit
Inventor: MAKINO TAKUYA
IPC: B24B41/04
Filed: 1992-04-10
Abstract: PURPOSE:To obtain an air spindle unit wherein its bearing stiffness is high in comparison with its volume and a high-speed rotation, high stiffness and high load capacity can be achieved at the same time, by receiving the outer peripheral side of the rotor yoke of a motor with a radial static pressure gas bearing. CONSTITUTION:Compressed air is fed into between a porous material 44 and the outer peripheral surface of a rotor yoke 42. Thereby, the rotor yoke 42 and an air spindle 26 are supported in a non-contact way by a radial static pressure gas bearing. Therefore, the whole length of the spindle 26 can be contracted, and the natural frequency of the shaft of an air spindle unit can be made high. Also, since the diameter of the shaft is changed midway, the area of a thrust bearing can be made large, and the area of the radial bearing is made large too, and moreover, by making the diameter thereof small, losses are suppressed. Therefore, the stiffness of the present air spindle unit is made high, comparing with any spindle unit having the same capacity as the present one. From these reasons, the high-speed rotation, high stiffness and high load capacity of the spindle unit can be achieved at the same time.

Abstract: PURPOSE:To exclude smoothly excessive carriers from a highly implanted region and to make possible a high-speed switching action by a method wherein a base region and an emitter region are made to selfalign and the emitter and base high-concentration regions are completely isolated from each other. CONSTITUTION:A wafer, in which an n-type epitaxial layer 103 is formed on a P-type Si substrate 101 through an n<+> buried layer 102, is used to form an emitter sidewall insulating film 115.

Boron is diffused in the substrate from the films 113 for external bases by the heat treatment at this time and the heat treatment at the time of formation of the film 115, and P<+> external base regions 116 are formed. After that, a nitride film 107 is removed to form an internal base layer 118, a poly Si film 119 is deposited and etched, an oxide film 106 is removed using the film 119 as a mask to deposit a poly Si film 120 and an emitter layer 121 is formed. Accordingly, the layers 116, 115 and 121 are formed by self-alignment and the layers 121 and 116 are isolated from each other.

Filed: 1985-06-04
Abstract: PURPOSE:To apply optimum control to the direction of the combined directivity in a short time by providing a directivity characteristic control means directing the combined directivity in a direction to control a reception signal adjusting device so as to obtain the best reception state based on the storage value of a storage means when the deterioration of the reception state is detected.

Title: Electronic wristwatch
Inventor: MATSUMURA EIICHI
IPC: H02P8/02
Filed: 1987-05-15
Abstract: PURPOSE:To detect the rotation of a stepping motor through a simple and low-priced detection circuit by discriminating the rotation of a rotor through detecting the back electromotive force of a coil. CONSTITUTION:Because no signal is generated in an exciting coil L when a rotor revolves, an electric current decided by a voltage VGS between a resistor R1 and the gate source of a transistor N1 flows also through a transistor N2. Therefore, when there is no signal in said coil L, the input of an inverter I is a high-level one, and its output a low-level one. When the rotor does not revolve and a voltage generated by the back electromotive force of said coil L is applied to the gate of said transistor N2 via a switch S2, the electric current of said transistor N2 increases and takes in all the electric current flowing through a transistor P2 and the output of said inverter I becomes a high-level one. Said high-level output of the inverter I allows detection of no rotation of the rotor of a stepping motor.
