Title: Braking force controller of vehicle
Inventor: YONEYAMA MASATOSHI
IPC: B60T8/24
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent braking force of a braking force control wheel from becoming excessively high so as to improve turning action of a vehicle by providing such a means as limiting a drop amount of a standard wheel speed when the braking force is judged to be controlled by an ABS control means with regard to the standard wheel. SOLUTION: A controller 10 has its braking force controlled so that a wheel speed of a turning outside front wheel may become a target wheel speed when turning action of a vehicle is in its unstable state like a spin. In this case, it is judge whether a turning inside front wheel is under ABS control or not and if it is not under ABS control without any possibility of quick drop of the wheel speed, a computed wheel speed is set to a standard wheel speed as it is.  On the other hand, when the turning inside front wheel is under ABS control and possibility of quick drop of the wheel speed can be expended, a drop quantity of the standard wheel speed is limited by correction of the standard wheel speed so that such control as allowing sudden reduction of the target wheel speed of a computed turning outside front wheel and sudden increase in the braking force of the turning outside front wheel can be prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device and a method therefor capable of enhancing the image quality and prolonging the life of an image carrier by sticking a low frictional agent to a toner supplied to the image carrier. SOLUTION: In the image forming device 10, an electrostatic latent image is formed in such a manner that a photoreceptor 11 uniformly electrified by an electrifying part 12 is irradiated with electrostatic latent image forming light by an optical writing part 13 and the toner of a developer 25 in a developing unit 24 is stuck to the photoreceptor 11 on which the electrostatic latent image is formed, in a developing part 14. The low frictional agent is externally added to the developer 25, in such a manner that the low frictional agent is mixed/kneaded/dispersed, porous grains obtained in such a manner that the low frictional agent is buried in a hole are mixed with the developer 25, when the developer 25 is of a two-component developer, carriers covered with the low frictional agent are mixed or the like.  Thus, the low frictional agent is stuck to the toner by an adequate amount, the coefficient of friction of the surface of the photoreceptor 11 is set <=0.4, especially, within the range of 0.1-0.3. Therefore, the wearing of the surface of the photoreceptor 11 is reduced to prolong its life and the image quality can be enhanced.

Title: Superconductive magnet protection device
Inventor: NOMURA HARUHIKO
IPC: H02H7/00
Filed: 1981-12-08
Abstract: PURPOSE:To prevent the generation of abnormal high voltage, when normal conductive transfer generates, and convert the accumulated energy into the other form of energy as rapid as possible, by using a rotary machine as the load for emitting the accumulated energy. CONSTITUTION:Since the rotary machine 7 performs the mutual conversion between electrical energy and mechanical energy and is all constituted of a rotor and a stator in the structure, the rotor has the moment of inertia in a considerable scale. This moment of inertia can store the rotational energy in the form of kinetic energy. When the voltage over the fixed level is detected in a superconductive magnet 3 by a voltage detector 6, and a switch 2 opens, electromotive force is generated in a reverse direction. But, even when this electromotive force is impressed on the rotary machine 7 via a diode 4, the rotor stands still at that point, and therefore the impedance of the rotary machine 7 is only a winding resistance resulting in the approximate short-circuit between A and B.

Title: Aluminum alloy for joining of ceramics
Inventor: FUKUZAWA YASUSHI
IPC: B23K20/00
Filed: 1988-08-08
Abstract: PURPOSE:To permit the direct joining of the title alloy to ceramics in high joining strength by specifying the content of Mn and Si in an Al alloy. CONSTITUTION:The compsn. of an Al alloy of joining of ceramics is composed of, by weight, 0.5 to 3% Mn, 0.5 to 5% Si and the balance Al with inevitable impurities. By the Al ally, at the time of joining of ceramics, Si diffuses on the ceramic side in an interface and solid-phase diffusion joining is executed. Furthermore, the strength of the Al alloy itself is increased by the coexistence of Mn and Si to obtain high joint strength. In this way, ceramics can firmly be joined in high joining strength without preliminarily forming a metallizing layer of Cu, Ag, etc., on the ceramic surface and without using harmful flux.

Title: Oscillation circuit
Inventor: MIYAHARA YASUHIRO
IPC: H03K3/02
Filed: 1991-08-07
Abstract: PURPOSE:To reduce current consumption and to decrease number of circuit components of an oscillation circuit including a charge discharge circuit. CONSTITUTION:With an output signal 101 set to an H level, a PMOS transistor(TR) 1 is turned off and an NMOS TR 4 is turned on. A current flows to the NMOS TR 3 being a component of a current mirror circuit and an NMOS TR 2 is going to supply the same quantity of current. Thus, the charge in a capacitor 8 is discharged through the NMOS TR 2 and an input voltage of a Schmitt circuit 7 is decreased. When the input voltage is lower than an L level input voltage of the Schmitt circuit 7, the output signal 101 goes to an L level, the PMOS TR 1 is turned on, the NMOS TR 4 is turned off and no current flows to the NMOS TRs 3,2. Thus, the current flowing to the resistor 5 flows to the capacitor 8, the input voltage of the Schmitt circuit 7 is increased and when it exceeds an H level, the output signal 101 goes to an H level.

Abstract: PURPOSE:To restore to a control condition before a power source interruption at the time of a power source restoration by storing a tally from a device to be controlled in a nonvolatile memory and inhibiting the tally of the nonvolatile memory to a power source detecting signal at the time of the power source interruption. CONSTITUTION:A nonvolatile memory 3 stores tally data from a device 4 to be controlled each time data contents change and holds storing contents even at the time of the power source interruption. The tally from a device 5 to be controlled to be supplied to the nonvolatile memory 3 executes an inhibition at an inhibiting circuit 5 when the power source of the device to be controlled is interrupted by the power source detecting signal from a power source detecting circuit 6. Thus, tally information just before the power source interruption is stored in the nonvolatile memory 3 when the power source is interrupted, and when the power source is restored, the storing contents of the nonvolatile memory 3 are read, re-supplied to the device 4 through a reading mixing circuit 2, and the condition before the power source interruption is restored.
