Title: Acceleration detection element
Inventor: NEGORO YASUHIRO
IPC: G01P15/18
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To provide an acceleration detection element capable of detecting the acceleration in two or more directions. SOLUTION: A base end side of a beam 4 is fixed to a supporting part 6 on a base plate 3. A weight 5 is provided on a surface of the base plate 3 on the tip side of the beam 4 which is expanded in the horizontal direction along a base plate surface through a clearance. The position of the center G of gravity of the weight 5 is away from the center axis of the beam 4 in the perpendicular direction so that the inertial moment is applied when the acceleration in the longitudinal direction (X-direction) is exerted. The tip surface of the weight 5 is the surface of a movable electrode 7, and a fixed electrode 8 is formed at the position opposite to the movable electrode 7 through the clearance.  When the acceleration in the X-direction or the Y-direction is exerted, the beam 4 is deflected vertically according to the quantity of the acceleration, and the weight 5 is tilted while it is displaced in the vertical direction, and the electrostatic capacity between the movable electrode 7 and the fixed electrode 8 is increased/decreased. The quantity of the acceleration is detected based on the change.

Title: Control method for motion of robot
Inventor: YABUKI AKIHIKO
IPC: G05B19/4063
Filed: 1986-10-23
Abstract: PURPOSE:To reduce the computation time required for restoring to a path, by generating a path restoring speed command vector from a present position to a scheduled path in a perpendicular direction, and controlling a motion. CONSTITUTION:A path restoring speed vector Vk is generated in stead of generating a targeted speed command vector in a direction of restoration to the path. In other words, the targeted speed command vector in the direction of restoration to the path can be divided into a speed vector in a direction of the path, that is, the targeted speed command vector Vdi, and a speed vector perpendicular to that, that is, the path restoring speed vector Vk. Therefore, by setting the speed vector Vdi constant invariably, and generating the speed vector Vk corresponding to the present position Pn, aberration from the path RP generated by an obstacle circuit can be corrected, and since the direction of the speed vector Vdi is constant in spite of position, it is not necessary to calculate a unit direction vector corresponding to the position, therefore, no complicated square-root calculation is required, and the computation time can be reduced.

Title: Substrate voltage generating device for dram
Inventor: TAGUCHI HIROYUKI
IPC: H01L27/108
Filed: 1992-09-22
Abstract: PURPOSE:To reduce power consumption required for refreshing operation and to facilitate holding data with a battery by applying a substrate voltage different from that of normal operation to a DRAM at the time of a battery backup mode. CONSTITUTION:When a DRAM substrate DR selects a normal mode M1, a substrate bias generating circuit 14 applies a first substrate bias VBB1 on the substrate DR. When the substrate DR selects a battery backup mode M2, a substrate bias VBB2 different from the first substrate bias VBB1 is applied on the substrate DR. In such a constitution, a leakage current from the source area of a memory cell in the DRAM to the substrate DR is reduced, a refreshing rate is further reduced and a low power consumption is realized. Consequently, the substrate voltage generating device of the DRAM easy in the holding of data with a battery is obtained.

Abstract: PURPOSE:To improve the accuracy of the near-point measurement of the eye to be examined and to shorten the time for the measurement. CONSTITUTION:A photoencoder 10 combined with a slit plate 11 is mounted as a means which movably supports a supporting plate 2 mounted with a fixed viewing mark 1 and detects the position of the fixed viewing mark 1.

The ophthalmorefractive power value in the near-point position of the eye E to be examined and the converted value of the refractive power of the viewing mark position are compared in the arithmetic control circuit 26. The near-point measurement is made by repeating the operations to part the fixed viewing mark 1 from the eye E to be examined and bring the mark again near to the eye when the decrease of a change in the ophthalmorefractive power value with a change in the converted value of the refractive power of the viewing mark position in the near-point position of the eve E to be examined attains a prescribed quantity.

Title: Dry developing device
Inventor: OGIYAMA HIROMI
IPC: G03G15/08
Filed: 1986-10-24
Abstract: PURPOSE:To remove remaining electric charges on a sleeve to completely recover a toner by applying a voltage having AC components between a rotatably provided electrode and the developing sleeve. CONSTITUTION:While a layer thickness control member 13, passes, the toner on a developing sleeve 12 has the layer thickness controlled and is triboelectrified by agitation at the time of movement to electrostatically stick to the developing sleeve 12. The toner on the developing sleeve 12 facing an electrostatic latent image on a photosensitive drum 10 is attracted to this latent image part because the potential of the latent image is higher. Meanwhile, the developing sleeve 12 after development of the latent image to a visible image bears the toner, which does not contribute to this development on the surface and faces an electrode 14 in this state. Since the voltage having AC components and a DC voltage are applied to the electrode 14, the toner remaining on the developing sleeve 12 is attracted to the electrode 14 by the component having the polarity opposite to the polarity of the toner out of the DC voltage and AC components. The remaining electric charge on the developing sleeve 12 is removed by the component having the same polarity as the toner out of AC components, and the toner stuck to the electrode 14 is scraped by the blade of a supply member 15.

Title: Amplifier circuit
Inventor: FUKUSHIMA AKIHIRO
IPC: H03G11/00
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier circuit which can prevent transient oscillation and latch-up of a power amplifier, etc., even the power amplifier is overdriven by a voltage amplifier. SOLUTION: The limiters L1 and L2 limit the output voltage of a voltage amplifier A which receives the power voltage ±Vcc1 and amplifies the input voltage. Then a power amplifier B which receives the power voltage ±Vcc2 (Vcc2>Vcc1) and is driven by the output voltage of the amplifier A is driven by the output voltage of a voltage amplifier 1 via both limiters L1 and L2 . When the amplifier B is overdriven by the output voltage of the amplifier A, the amplifier B is driven by the voltage that is limited by the limiters L1 and L2. Thus, it's possible to prevent transient oscillation and latch-up of the amplifier B.
