Title: Wiper device with reversible rotation
Inventor: KANOMOTO NORIYUKI
IPC: H02P1/22
Filed: 1989-09-15
Abstract: PURPOSE:To allow the total wiping angle as the sum of slip angle and wipe command angle to approach a constant value by measuring the time in which a wiper blade passes the wipe command angle, and emitting a drive signal so that the slip angle enlarges with longer time. CONSTITUTION:A location sensing means 3b senses a wiper blade passing a specified wipe command angle, and this time of passage is measured by a microcomputer 2a. The current fed to a wiper motor 3a is controlled by a driver circuit 2b so that slip angles V21, V22 enlarge as this time of passage is longer. That is, the time for the blade passing through the wipe command angle becomes longer when the surface of windshield is dry or when dirt, etc., is attached thereto. At this time, signal is given to the drive circuit 2b from the computer 2a so that the slip angles V21, V22 will enlarge. Thus the wiping angle as the sum of command angle and slip angle approaches the constant condition.

Title: Permanent magnet motor for electric vehicle
Inventor: MIZUNO TAKAYUKI
IPC: B60L11/18
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent the adverse influence of the generation of a remarkable brake torque or large current to an inverter or battery side even when the inverter is turned off by so setting the induced voltage at the maximum speed induced in the winding by a permanent magnet as to become substantially equal to the open voltage of the battery. SOLUTION: If the inverter of a permanent magnet motor is turned off due to a certain cause, the motor serves as a generator and an excess current flows according to the amplitude of the induced voltage via the circulating diode of the inverter. The current Ia flowing at the time of turning off the inverter is decided by the motor induced voltage E0 , the battery open circuit voltage V0 , battery internal resistance R1 and motor winding resistance Ra. Accordingly, the adverse influence of the generation of remarkably large brake torque and large current to the inverter or battery side can be prevented.

IPC: B01D12/00
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To obtain excellent dewatering and drying property and to efficiently extract, separate and collect a low mol.wt. siloxane by removing water from the objective material by using a dewatering agent containing a low mol.wt. siloxane and a hydrophilic solvent and then extracting and collecting the low mol.wt. siloxane with water from the dewatering agent. SOLUTION: The dewatering agent consists of a low mol.wt. siloxane and a hydrophilic solvent such as alcohols, glycols and water-soluble alcohols as derivs. of these with addition of a surfactant such as polyoxyalkylene alkylethersulfonate and a stabilizer such as glycidol. In this dewatering agent, water added in an excess amt. of saturation solubility is separated. The separated water extracts the hydrophilic solvent in the dewatering agent and breaks the balanced state of solubilities between the hydrophilic solvent and the low mol.wt. siloxane to separate the hydrophilic solvent from the low mol.wt. siloxane. Further, by adding water to a certain amt., the water content in the low mol.wt. siloxane in the upper layer moves to the hydrophilic solvent in the lower layer. Thus, the low mol.wt. siloxane of high purity can be easily separated and collected.

Title: Switch input circuit
Inventor: HAYASHIBARA TOSHIO
IPC: H03K17/00
Filed: 1991-09-20
Abstract: PURPOSE:To suppress increase in heat and cost by supplying a current through a capacitor to a switch. CONSTITUTION:A current flows when switches S1, S2 are closed to only resistors R1, R2 because a transistor(TR) T1 is always turned off and then the current is less. Thus, improper contact is caused due to the oxidation of a contact. Then the current is supplied by turning periodically the TR T1 ON. With the TR T1 turned on, a current flows momentarily to the switches S1, S2 through capacitors C1, C2 through the TR T1 from a high voltage power supply VB to secure sure contactness of the contact. With the TR T1 turned off, a charging voltage across the capacitors C1, C2 is discharged by a resistor R8 and a capacitor C3 and a voltage of a line E2 reaches 0. In this case, the capacitors C1, C2, C3 act like filters against noise induced on a line connecting to the switches S1, S2.
