Title: Pulse-width modulator
Inventor: ISHII SATORU
IPC: H03K7/08
Filed: 1978-12-28
Abstract: PURPOSE: To increase a modulation rate by nearly equalizing at any time the non- conduction time when upper and lower pulse amplifiers are both OFF.  
     CONSTITUTION: When triangular wave a' whose duty cycle is set to any value than 50% is applied to one-side input terminals of upper and lower comparators 5 and 5', it is compared with positive potential (b) by comparator 5 to output a positive output pulse of waveform (d) and compared with negative potential (c) by comparator 5' to output a negative output pulse of waveform (e). Both outputs are applied to pulse amplifiers 6 and 6', so that a pulse waveform outputted from mixer 7 lastly will have non-conduction periods T 1  and T 2  nearly equal each other as shown by (f). As a result, the non-conduction time when an acoustic signal is applied to the signal input can be shortened to its minimum, so that its modulation rate can be increased.

IPC: C02F1/62
Filed: 1994-07-13
Abstract: PURPOSE:To make it possible to calculate easily the amount of SS generated by the neutralization of raw water by calculating the amount of an insoluble material generated by chemical reaction between alkali and drained water based on the amount of consumed alkali, in a device for generating the insoluble material by adding alkali to drained water containing metal ion. CONSTITUTION:A raw water tank 1, a preliminary neutralization tank 2, a neutralization tank 3, a flocculation tank 4, a sedimentation tank 5 and a reaction tank 6 are installed, and an insoluble material is generated by adding alkali to drained water containing a metal ion, and this insoluble material is separated as sludge from treated water. In addition, the alkali is added to a part of the separated sludge, and a mixed product thus obtained is added to the drained water to obtain a high sludge concentrate which can be highly dehydrated. In this case, the concentration of SS is calculated by a control device 10 using an SS coefficient based on a required amount of alkali for adjusting the pH value of raw water to a specified level. In addition, a return rate is calculated based on the concentration of SS, the concentration of returned sludge, the flow of returned sludge and the flow of raw water, and the discharge amount of a sludge return pump P4 is controlled so that the return rate shows a specified value.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic force engine and a large-sized generation plant, in which one-directional magnetic force difference having repulsion, attraction of permanent magnets and magnetic bodies is used as basic torque, short magnetic force is compensated by returning lattice magnetic body mechanism and further attraction, and the permanent magnets are replaced with superconducting magnets depending upon the roles assumed. SOLUTION: Efficiency is attained by utilizing repulsion and attraction of permanent magnets 1a, 1b, 1c together. Appropriate magnetic bodies 1a, 1b, 1c are attached for providing effective angles such as appropriate approaching angle θ and retreating angle β. Approaching resistance is reduced due to attraction by utilizing the difference in diameter (R1-R2) of rotors 11, 10. Lattice magnetic bodies are opened and closed on an approximated repulsion conversion curved surface for collecting repeated magnetic force. Short magnetic force is further extended by attraction of a lift cam.

By the same way, a plurality of test samples are prepared. These samples are turned in a turning type agitator such as a ball mill at a suitably determined constant turning speed. Thus a developing agent is mixed and agitated. The total amount of the developing agent is taken out of the test samples after the agitation, and the charged quantity at every turning is measured with a blow-off charge measuring device. Thus the charging characteristic of the toner can be determined. In this way, the friction and charging characteristics in the toner and the carrier can be accurately measured simply, and the characteristics having high reliability can be determined.

Abstract: PROBLEM TO BE SOLVED: To provide excellent battery inner pressure characteristics while maintaining a state of high initial activity by treating a hydrogen storage alloy electrode by a solution containing a complex ion having its unpaired electrodes in a higher energy level than an orbit comprising a hybrid orbit forming the complex ion. SOLUTION: A hydrogen storage alloy used for an electrode is treated in a solution containing a complex ion having its unpaired electrode in a higher energy level than an orbit comprising a hybrid orbit forming the complex ion. A typical example of the complex ion includes [Co(NH3 )6 ]<2+> . Through this treatment, metal oxidation such as nickel segregated on an alloy surface is restrained by reduction action due to no-pair element, and a metal layer can be formed on the alloy surface. As a result, hydrogen storage reactivity on the alloy surface is improved, and an initial battery inner pressure or the like is reduced. For a complex ion, it is preferable that a ligand whose capacity of dividing a d-orbit stronger than H2 O is coordinated. In addition, it is preferable that a center ion has seven d-electrons, and Co, Rh, or Ir is preferred.

Abstract: PURPOSE: To prevent a danger by controlling so that the clutch is not coupled directly at the higher prescribed engine speed at the idling time.  
     CONSTITUTION: A current proportional to the rotating speed flows through a coil 7 with an H signal from an accelerator detector 44, and when it is accelerated to cause the rotating speed to become N 1 , a transistor 49 is conducted with the H signal from a clutch direct coupling circuit 46, it is also maintained when the rotating speed is lowered, and when the rotating speed is lowered to the N 2  in the engine brake state, it is released. When the transmission becomes neutral, an L signal is applied to the AND gate 52 when the switch 40 is ON, and the gate 52 produces an L signal irrespective of the operation of the accelerator switch 39. Accordingly, the AND gate 53 becomes L regardless of the output of a wave shaper 54, and the clutch direct coupling circuit 46 does not  produce the H signal for the direct coupling.
