IPC: H03B5/04
Filed: 1978-04-21
Abstract: PURPOSE:To compensate oscillation frequency drift by changing the base potential of transistors (Tr), which form an oscillator circuit, according to temperature change. CONSTITUTION:The output (the output form collector 18) of control circuit 2 where Tr13 having temperature detection and signal amplification functions is connected between power source VCC and the earth through a bias resistance is inputted to control input end 19 of oscillator circuit 1 which has tank circuit 10 and consists of differenatial type Tr6 and 7. In this case, though bias potential VC of the base of Tr13 is changeable due to temperature rise, voltage VBE across the base and the emitter is reduced to increase current IQ3 flowing to Tr13. Then, output voltage VB of collector 18, namely, the base potential of Tr6 and 7 is reduced, and base collector junction capacity CD is reducted. By this capacity reduction, the value  of other element parameters of Tr6 and 7 is increased accompanied with temperature rise to compensate the inclination for reducing the oscillation frequency of  circuit 1, so that the oscillation frequency can be held constant independently of temperature change.

Title: Magnetic bubble memory device
Inventor: NAKAGAWA YUSUKE
IPC: G11C19/08
Filed: 1986-03-06
Abstract: PURPOSE:To prevent a malfunction in the bubble retransfer stage of a magnetic bubble memory by disposing a minor loop with inclination >=3 deg. in the direction opposite to the rotating direction of a rotational driving magnetic field for bubble transfer. CONSTITUTION:The minor loop 24 is disposed with inclination >=3 deg. in the direction opposite to the rotating direction of the rotational driving magnetic field HD for bubble transfer relative to the vertical direction of a start-stop direction 28 shown by an arrow when the minor loop 24 to stop the bubble exists near a pattern gap. The bubble eventually stops in the position where the phase of the rotational driving magnetic field is advanced by several degree if the memory device is constituted in the above-mentioned manner. All the stop positions are, therefore, the position beyond the gap. The area of 'Permalloy(R)' is larger in the pattern after the gap than before the gap with the gap in-between with a 'Permalloy(R)' element in general. Since the bubble is more liable to be retracted with such element, the operation of the start-stop is stabilized and the malfunction generated by the jump out of the pattern in the bubble retransfer stage is prevented.

Title: Electrostatic microactuator
Inventor: ESASHI MASAKI
IPC: H01L49/00
Filed: 1992-03-04
Abstract: PURPOSE:To make it possible to take out the displacement and the deformation accurately with simple structure and easy operation by making the device so structured that the plurality of fine cylindrical elastic bodies, each having a cylindrical conductor with an insulator located on the most outer surface, are located adjacently to each other and are connected as requested. CONSTITUTION:When voltage is applied to an electrostatic microactuator, charge is generated in fine cylindrical elastic bodies 1 which are adjacent to each other in the X direction. At that time, the charges generated in the two adjacent elastic bodies are different. Therefore, tone two adjacent elastic bodies are attracted by an electostatic force and thereby the actuator has the deformation. This deformation is used as a motion of the actuator. Each of the fine cylindrical elastic bodies which constitute the actuator has a cylindrical conductor 3 which has an insulator 2 located on the most outer surface and an elastic body 4 formed of soft polymer or other material is placed inside the conductor 3. This part can be manufactured easily by using a fine processing device, etc., which is used for manufacturing a semiconductor. The deformation control can be done accurately by controlling the electrostatic force. Therefore, a small-size, fine and very accurate microactuator can be obtained with simple structure and easy operation.
