IPC: H02P7/29
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce the through current of a diode for eliminating radio noise and/or the power consumption of an FET by providing a drive control means for driving a pair of the FETs for performing PWM drive at a different timing for each FET. SOLUTION: Each of a gate G11 of an FET Q11 and a gate G12 of an FET Q12 is independently connected to a drive control means 2. Then, a G2 used as the common connection point of the gates of FETs Q21 and Q22 is connected to the drive control means 2. The drive control means 2 is provided, where the means 2 drives a set of the FETs Q11 and Q12 for performing PWM driver at different timing for each FET, thus limiting the FET for performing the PWM drive for allowing through current to flow to diodes D21 and D22 to one FET Q11, and allowing the other FET Q12 to reduce the through current by the PWM drive after the recovery time of the diodes D21 and D22.

Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To reduce the building cost of impervious walls, to shorten the work period thereof and to decrease the space for installation. SOLUTION: Prescribed trenches 21 are formed by using a stabilizing liquid 22, such as mud water, on the circumference of a storage space 3 for storing contaminated materials. Water impermeable cage bodies 23 which do not allow the permeation of solidifying materials are then disposed in these trenches 21 and pipes 11 for monitoring are built in the cage bodies 23. Drain materials 13, such as crushed stones, are charged into the cage bodies 23 on the outer side of the pipes 11. The solidifying materials, such as concrete, are then packed and substituted between the cage bodies 23 and the trenches 21, by which double walls 9, 10 are formed.

IPC: G01C3/06
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To accurately process a pair of position signals with a simple configuration. SOLUTION: A pair of position signals I1 and I2 outputted from a PSD 4 are mixed in time series by a switch circuit 191 and are converted from an electrical signal into a voltage signal by an I/V circuit 7. The voltage signal is amplified by an amplifier 8 and is synchronized and detected by a synchronization detection circuit 9. The output of the synchronization detection circuit 9 is alternately outputted to a pair of LPFs 111 and 112 for each constant period by a switch circuit 192 . Namely, the mixed position signal is separated by the switch circuit 192 . The output of the LPFs 111 and 112 is processed by an operation part 12, and an analog signal corresponding to the distance or the displacement of an object A is outputted.  Since there are only one system of the I/V circuit 7, the amplifier 8, and the synchronization detection circuit 9, a pair of position signals can be accurately processed with a simple configuration.

IPC: G03G15/08
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To discriminate, at a low cost without many special components but with a smaller number of components, whether components of an image forming unit is new or not, when the unit is attached to an image forming device main body. SOLUTION: At the start and end of a reset operation, which is performed when the cover of the image forming device main body is closed for example, the image forming device causes a current to flow between a developing roller 21 and a conductive member, such as a conductive thin-layer blade 23 or a conductive Mylar, which elastically contacts it. In the case the newly-attached image-forming unit is a fresh one, toner 45 sticks to the periphery of the developing roller 21 due to the reset operation and the value of resistance becomes high and, therefor, based on a difference between the value of the current flowing at the start of the reset operation and that at the end of it, the device judges whether the attached image-forming unit is a fresh one or not.

Title: Swaying swash plate type compressor
Inventor: OOTA MASAKI
IPC: F04B27/14
Filed: 1985-10-02
Abstract: PURPOSE:To make it possible to maintain the intake pressure constant, by absorbing the compression reaction into a spring resisting a negative moment imposed on a swash plate, when the variation of the intake pressure to a crankcase pressure of a set value converts the inclination of the swaying swash plate. CONSTITUTION:A crankcase 17 is formed to keep its pressure at a constant value by furnishing a supply route 37 switchable linking a discharge chamber 7 and the crankcase 17, and a linking route 27 to connect the crankcase 17 and an intake chamber 6. And is furnished a spring 41 having a performance to resist and set off a force of the compression reaction acting in the direction to reduce the inclination of a swaying swash plate 21 according to the inclination. When a variation of the intake chamber 6 pressure converts the inclination of the swaying oblique plate 21 against the crankcase 12 pressure kept at a set pressure, the compression reaction is absorbed to the spring 41 which resists a negative moment imposed on the oblique plate 21, and this absorved pressure is made possible to keep about at a constant value. Therefore, a rise of the blowing temperature of an evaporator can be prevented, and an unpleasant feeling for a driver can be perfectly avoided.

Title: Treatment of waste
Inventor: KANEKO YUKIO
IPC: B09B3/00
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To enable waste to be treated by a simple method which dispenses with the addition of a reaction additive through melting the waste containing heavy metals and causing a centrifugal force to act upon the waste in a molten state. SOLUTION: A waste is supplied into a rotary crucible 2 through a supply aperture in such a state that the rotation of the rotary crucible 2 is suspended. Further, the waste loaded in the rotary crucible 2 is caused to melt by a Joule heat by applying an AC current from an AC power supply 5 to an energizing coil 4. After the waste is molten to some extant, the whole rotary crucible 2 is caused to rotate through a rotating shaft 6 by a motor 8, and heavy metals whose specific gravity is high gradually move to the peripheral face 2b side from the center part of the rotary crucible 2 by a centrifugal force. In addition, the centrifugal force to be applied to the waste becomes high by increasing the number of rotation of the rotating shaft 6 with the melting of the waste.  Consequently, the melt of the heavy metals whose specific gravity is high finding its way out of a gap between the bottom face 3a of a lid 3 and the upper face 2c of the rotary crucible 2 overflows from the rotary crucible 2 to be separated from the waste.

Abstract: PURPOSE:To prevent the missing of data and to eliminate the delay of processing time by deciding an overload in respective subsystems, and executing the distributed processings of input data at time of said decision in accordance with a data selecting table provided in the respective subsystems. CONSTITUTION:When not in a overloading state, the input data passes through the overload deciding parts H1-Hn of the respective subsystems SS1-SSn. If an overload state is generated, the overload deciding parts H1-Hn decide the state, and the selecting/omitting of the input data is determined by using the data selection tables D1-Dn. Output data from the overload deciding parts H1-Hn or from the data selection tables D1-Dn are processed in processing parts P1-Pn. In such a case, since the data selection tables D1-Dn is so set beforehand that the entire data to be the object of the processing can be made up with the whole selected data, the processing is distributed throughout the entire multiplexing system.
