Title: Floating separation method for sludge
Inventor: MUTOO EIICHI
IPC: B03D1/02
Filed: 1980-02-19
Abstract: PURPOSE: To perform floating separation of sludge effectively and continuously without requiring any large driving power by bubbling the air dissolved in the sludge by making use of the evacuation generated by siphon effect thereby floating and separating the solids in the sludge.  
     CONSTITUTION: When valves 12, 14 are closed and a vacuum pump 10 is operated, an evacuation separating tank 3 is evacuated and sludge is sucked through a supply pipe 2 from a sludge supply tank 1. The air dissolved in the sludge is bubbled from the sludge sucked into the tank 3 in an evacuated state, and the particles in the sludge are absorbed by the these bubbles and while they are being floated and separated, the sludge is filled in the tank 3. When the sludge reaches to the valve 12 in the position below the level of the sludge supply tank 1 and the valve 12 is opened, siphone effect is produced by the weight of the sludge and the water level difference, and the sludge is supplied and discharged by siphon effect by making use of virtually no external force. Because of the evacuated state in the tank 3, the sludge is successively floated and separated, and the concentrated sludge is forcefully discharged by the cooperation of the siphon effect and the driving of a delivery device 11.

Title: Gate control system
Inventor: IWAMOTO KENGO
IPC: H02M1/08
Filed: 1978-02-24
Abstract: PURPOSE:To reduce the equivalent disturbing current dependent upon a high frequency current by performing simultaneously the phase control of control rectifiers so that the ignition time of one control rectifier may be delayed by the period corresponding to the commutation overlap angle of the other control rectifier. CONSTITUTION:Control rectifier 31' is controlled at the phase control angle, which advances always more than the phase control angle of control rectifier 32 by overlap angle components, by subjecting control rectiffier 31' to reverse conversion control. That is, the control by which outputs of DC voltage detectors 91 and 92 are always equal to each other and the phase control angle of control rectifier 32 is delayed more than the phase control angle of control rectifier 31' by overlap angle components results in the reverse conversion control of control rectifier 31'. As a result, the control phase angle between unit DC loads can be inevitably controlled with an angle corresponding to the overlap angle, and the gate control system having a small equivalent distubing current can be realized.

Title: Image forming device
Inventor: SUDA MASAJI
IPC: G03G15/04
Filed: 1983-02-10
Abstract: PURPOSE:To make a beautiful copy of a thick original such as a book by performing manual switching so that an image formation area is reduced for a small original, and stopping the formation of a latent image corresponding to an ejected nonimage formation area. CONSTITUTION:For example, when a book 12 is placed on platen glass 11 and its scanning-directional width L' is smaller than the width P of a standard image formation area in the scanning direction, a solid black part is prevented from being formed at an end part of a copied form. When the magnet M on a lamp unit 16 comes right under a sensor S, the lamp unit 16 and moving mirrors 17 and 19 stop moving as shown by an arrow (a) and never make a scan on the original up to the width P. Further, a photosensitive drum 22 is exposed on blank basis by a blank exposure source 27 on the completion of the original scan, so the copied transfer material has no solid black part.

Title: Apparatus for driving electric motor vehicle
Inventor: SHIBAMOTO MASAHIKO
IPC: H02P25/06
Filed: 1979-02-23
Abstract: PURPOSE: To utilize the wheel driving force of an electric motor vehicle at as much adhesion limit as possible by controlling the frequency of an AC power supply for energizing an induction motor and a linear motor for driving the vehicle in response to the automotive body speed.  
     CONSTITUTION: An induction motor 10 for rotating wheels 3 through a reduction gear 2 is controlled, for example, by a pulse duration modulation type variable voltage and variable frequency (VVVF) inverter 11. A vehicle speed sensor 7 generates a frequency equal to the frequency of the inverter when the motor 10 is rotated at synchronous speed. A linear motor 5 is connected in parallel with the motor 10 to produce driving force in the same direction as the drive wheels 3. The output signal f 1  from the sensor 7 and a slip frequency f 3   from a slip frequency pattern circuit 12 are applied to a frequency adding or subtracting circuit 13, which thereupon adds the inputs when motoring the vehicle and substracts when regenerating the vehicle. Accordingly, the output of the inverter 11 applied to the motors 10 and 5 controls the slip frequency constant at both motoring and regenerating times.

IPC: B21D5/01
Filed: 1979-02-23
Abstract: PURPOSE: To enable the undeformed band length after forming to be formed effectively short with less forming force by so forming the material to be formed that the material to be formed and a lower die do not contact except the end part of the material to be formed and the contact part of the lower mold from the start of forming until completion.  
     CONSTITUTION: In the foregoing one point contact forming, the dies of the construction in which not only the material to be formed 8 makes contact with a lower die 6 with its end part 9 at all times during forming but also the end part 9 may be closely contacted to an upper die 5 even at the extreme limit of C-forming (undeformed band 14 length lF=O) is required. To this end, the offset amount F of the curvature centers OU, OL of the upper and lower dies are so selected that the angles ψ, θ of the case when it is assumed that the material 8 made close contact with the die 5 become ψ-θ>0. At the same time there is a need for arranging the dies in such a manner that the material 8 and die 6 do not contact at the parts other than the end part 9 and contact point 10 from the start of forming until completion. Because of this, the upper and lower die curvature radii RU, RL, offset amount F, die 6 length, etc. are correctly selected. Here, RL≥RU is easier to execute but RL< RU is equally well.

Title: Detection circuit for detecting duty cycle of signal
Inventor: HAYAKAWA MITSURU
IPC: H03K3/017
Filed: 1987-01-30
Abstract: PURPOSE:To deal with the variation of a time constant, by forming a retriggerable monomultivibrator wherein the time constant is set corresponding to a limit value from a trigger circuit, a lamp voltage generating circuit and a voltage comparator of which the reference voltage is subjected to feedback control. CONSTITUTION:The input signal having an average cycle tau0 through a limiter LIMIT is supplied to a retriggerable monomultivibrator RTMM1a having a time constant slightly shorter than the one-cycle length of a lower limit and a positive polarity detection pulse is outputted during a period of reference voltage Vs or less trigger circuit TRC1, a lamp voltage generating circuit REG1 and a voltage comparator COMP1. Since this voltage Vs is the one wherein the output of the comparator COMP1 is subjected to feedback control through an integration circuit INTC and a variable amplifier A to which set voltage is supplied, a detection pulse having the cycle tau0 and a predetermined ratio is outputted from the comparator COMP1 when input is a duty cycle of a lower limit length or more even when the time constant is changed by the characteristic irregularity of a constitutional element or temp. The detection of a duty cycle of an upper limit length or less is similarly performed.

Title: Exhaust silencing system in internal-combustion engine
Inventor: MORIBE HIDEO
IPC: F01N3/04
Filed: 1983-02-09
Abstract: PURPOSE:To effectively de-heat exhaust gas, reduce its pressure, and effectively silence the high temperature and high pressure exhaust gas by inserting one end of a heat pipe into a muffler, etc., and arranging the other end thereof in a heat exchanging medium. CONSTITUTION:Exhaust gas at high temperature and high pressure exhausted from an engine reaches an exhaust pipe 3, flows into a de-heating chamber 51 of a heat exchanger 5, and heats one end of a heat pipe 52 arranged in the de- heating chamber 51 via a fin 521. Accordingly, water encapsuled within the heat pipe 52 changes to vapor, which then moves in the heat pipe 52 toward the other end of the heat pipe with a high speed. And, the vapor reaching the other end of the heat pipe 52 is cooled by means of a pipe wall contiguous to the atmosphere, condensed, and again changes to water, while emits evaporation latent heat via the fin 521. The water again returns to one end of the heat pipe 52, and repeats the above process. Hereby, exhaust gas is effectively de-heated, and its pressure is deduced, allowing silencing of the exhaust gas to be effectively performed.
