Title: Suction device for engine
Inventor: ONISHI KOJI
IPC: F02B29/08
Filed: 1985-10-11
Abstract: PURPOSE:To aim at improvement in suction efficiency and stabilization in combustion, by installing a rotary on-off valve in a suction passage, synchronizing it with an engine speed, and making its on-off timing variable, while installing a suction turnover part at the upstream of the on-off valve, and also installing a swirl forming port in addition. CONSTITUTION:A rotary on-off valve 18 is installed in a converging part at the upstream of an independent suction passage of each cylinder 3, rotating it by a crankshaft 24 of an engine via a belt 26. An on-off timing adjuster 22 is installed in this driving system, whereby the suction passage is made so as to be opened by a control unit 31 at the specified timing after opening a suction valve 7 according to engine load and speed. At the time of opening, suction pulsation pressure is turned over at a part of an expansion chamber 16 at the upstream of the valve 18, thus charging efficiency is improved. A suction flow velocity at that time is speedy, making it into a high swirl by a swirl port form, and thereby combustion is stabilized. At the time of driving when neutralizing a function of the on-off valve 18, a valve 20 in a bypass passage 19 is opened.

Filed: 1982-12-27
Abstract: PURPOSE:To obtain a copied product easy to handle by starting and stopping a copying operation when a pulse count value corresponding to the distance of an original being moved is compared with the first and second prescribed values and it coincides with them. CONSTITUTION:When the signal Sm of the forward end of an original is sent from an original detector 10 to an original length counter 27, it begins to count successive pulses sent from the pulse generator 28 of an original conveying part in reply to the signal Sm, and sends its count value Vc to a comparison circuit 29. The generator 28 generates one pulse each time the original moves by 10mm.. The Vc value is compared with a copy start set value Vs and a copy end set value Ve sent from a copy start position counter 31 and a copy end position counter 32 in the comparison circuit 29. Vs and Ve are optionally set with an operation part 33. When Vc coincides with Vs and Ve, a copy start signal Si and a copy end signal Se are produced, respectively, and a copied product easy to handle is obtained.

Filed: 1992-08-26
Abstract: PURPOSE:To obtain a highly accurate tube without dimensional fluctuation by rolling after supplying a lubricant through a hollow mandrel and injecting the lubricant on the inner surface of a hollow tube stock before rolling. CONSTITUTION:This method is a method for rolling a seamless steel tube by using a mandrel mill 2 in which the hollow tube stock 1 is continuously rolled with grooved rolls and the mandrel 5.

IPC: H03K3/037
Filed: 1988-09-09
Abstract: PURPOSE:To prevent malfunction with simple constitution by having only to add a gate element so as to prevent racing due to a delayed clock from being caused in the case of connecting plural stages of flip-flops. CONSTITUTION:In the case of connecting plural stages of flip-flops, an AND gate 24 is used as a gate element. If a clock(CK) inputted to a master slave flip-flop 21 and a clock(CK2) inputted to a master slave flip-flop 22 of the next stage are deviated, even if the clock CK goes to an H level, if the clock CK2 remains at an L level, an output B of the AND gate 24 remains at L level, and since no clock signal is outputted to an inverter 11 and a transmission gate 13 till the clock CK2 goes to an H level, racing due to clock skew is not caused. Thus, malfunction is prevented with simple constitution.

Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To shorten a construction period by inserting a steel column through a bored hole in a column in a new building body, and fixing a leg part to a foundation slab of the new building body on an existing foundation slab or a foundation slab of an existing building body. SOLUTION: For example, in the case of constructing a foundation beam 6 on the side of a foundation beam 8 of an existing building skeleton, reinforcements of the foundation beam 6 to be connected are disposed in a steel column 2 after fixing the steel column 2, and concrete is placed. In this case, a bored hole in an existing slab 1 is closed with reinforcements and concrete, and the existing slab 1 is used as a slab for a new building skeleton. When an existing foundation beam 8 is unnecessary, it is demolished after construction of the foundation beam 6, or at the time of construction of it, and when it has no hindrance with the new building body, demolition is not required.  Work efficiency and safety for new construction are thus improved, temporary construction work is reduced or eliminated to reduce construction cost, and the period from demolition to new construction can be shortened.

IPC: G11B7/09
Filed: 1991-08-13
Abstract: PURPOSE:To check abnormal input of a track deflection amount by checking the gain of input/output system by comparing the input signal applied to displace an actuator with a driving signal of a displaced actuator. CONSTITUTION:The inputted check command is detected by a CPU 14. The CPU 14 outputs, with an intention of executing a check 1, a loop switch OFF signal in order to turn off a servo loop switch 16. The CPU 14, with regard to the digital signal outputted according to an azimuth amount, executes arithmetic processing to find whether detected value = K X input value or not with regard to a driving current applied to an actuator 6. When the CPU 14 confirms that there is no abnormality by check 1, then executes check 2. The CPU 14 executes an arithmetic processing to find whether input value = AX2x/X (diameter side) input value = AX2 (X-x) /X or not by moving a card type optical recording media. If the above stated results are not obtained, the CPU 14 decides that x is properly detected, and then notifies an operator of its normality.

Abstract: PROBLEM TO BE SOLVED: To allow the element to conduct an logical arithmetic operation regardless of a fewer number of transistors(TRs) through the configuration of the element such that an input signal controls excitation of each transistor(TR) and a comparison inverter compares an output voltage signal appearing based on a sum of drain currents of each TR with a threshold level and provides an output of comparison result. SOLUTION: An amplification factor β is set to MIS TRs 21, 22,...m corresponding to respective ωi so as to set a threshold level of a comparison inverter 30 at a value corresponding to '1' in a term sin(ΣωiXi-1) of a logical equation Y=sin(Σω-iXi-1), where ω=Wi/T (Wi is a weight of an i-th input and T is a threshold level). One terminal of each of the MIS TRs 21, 22,...m is pulled up to a power supply and the other terminal of each of them connects to ground via a TR 20. Then drain currents of the MIS TRs 21, 22,...m are summed and a voltage depending on the cross-reference between the sum current and an output of the TR 20 is given to the comparison inverter 30 which compares the voltage with a threshold level.

Abstract: PURPOSE:To minimize an overshoot in controlling a stop amount and to prevent a bound phenomenon by changing the width of a stabilization area depending on the difference among the value and the standard upper limit value and the standard lower limit value of a brightness and darkness signal corresponding to the brightness of an object. CONSTITUTION:When the image of the object is formed on an imaging element 3 via a lens system 1, an image signal is outputted and a brightness and darkness signal BS corresponding to the brightness of the object is extracted through an LPF 4. The signal BS is consecutively converted into brightness and darkness data BD at a certain time interval through an A/D converter 5 and supplied to a microcomputer 6. The microcomputer 6 re-sets an upper area set value E or a lower area set value F corresponding to the difference among a value A, a standard upper limit value C and a standard lower limit value B of the signal BD, and sets the stabilization area X1 or X2 expanded toward the upper side or lower side. When the value A is moved into the area X1 or X2, an iris motor 2b is once stopped, taking into account the overshoot afterward.
