Title: Doubly woven bag for civil engineering work
Inventor: NAKAMURA YUKICHI
IPC: E02D17/20
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent a laying area from being reduced when filling matter is filled into a doubly woven gag by forming the confounding thread of a connecting thread of the doubly woven bag to be laid down on a slope so that its cutting strength is a specified number of times or more the cutting strength of a core thread. SOLUTION: A connecting thread for connecting the surface and back cloths 2a and 2b of a doubly woven bag 1 to each other is formed in an air-mixed woven thread in which the cutting strength of a confounding thread 3b is ten times or more the cutting strength of a core thread. In this case, an air-mixed woven thread in which the length of a confounding thread is 1.2 to 3 times the length of the core thread is used. Also the doubly woven bag 1 is laid down at a prescribed place, and filling matter 4 such as concrete, mortar, and bentonite is filled into it. Then the core thread is cut off by a filling pressure, and the surface and back cloths 2a and 2b of the doubly woven bag 1 are connected through the confounding thread 3b. By this, the interval between the surface and back cloths 2a and 2b is expanded.  Because the filling matter 4 is filled in the expanded space, the laying area for the doubly woven bag 1 is not reduced. Thus a laying and filling on laying surfaces such as slope can be performed efficiently an accurately.

Title: Motor-driven remote-controlled mirror
Inventor: NAGAYAMA YOSHIRO
IPC: B60R1/06
Filed: 1990-10-26
Abstract: PURPOSE:To obtain such a motor-driven remote-controlled mirror as to enable switching operation between the normal travel state and the rear wheel confirming state without affecting the control accuracy of remote control and also to be restorable accurately at the time of being operated to be restored into the stored normal travel state from the rear wheel confirming state. CONSTITUTION:When a motor 10c is operated from the state of the support angle of a mirror body 4 being adjusted as desired so as to screw-feed an advancing/receding rod 5b in the elongated direction, a ball joint 2 is turned fully to act as a stopper, and resistance is applied to a transmission member. The engagement between a driving rectangular shaft 13a and a base gear 13b is thereby released, so that the driven side is stopped, and the driving side races. As a result, the mirror body 4 is tilted downward to obtain the rear wheel confirming state. When the motor 10c is then operated again to rotate the base gear 13b and the driving rectangular shaft 13a reversely, the advancing/receding rod 5b is contracted so as to tilt the mirror component 3 upward. When the advancing/receding rod 5b is fully contracted in relation to a nut member 12, the engagement between the base gear 13b and driving rectangular shaft 13a is released to complete restoration and to obtain the normal travel state.

Filed: 1991-11-01
Abstract: In order to heat a heating material (3) or a substrate to be coated in a vacuum chamber (1) or in a bell jar uniformly by means of gas discharge or low-voltage arc discharge, it is proposed that at least one locally variable and/or displaceable magnetic field is maintained in the vacuum chamber or in the bell jar at least during heating. Preferably, at least two partially overlapping magnetic fields are maintained and these are alternately driven more strongly or more weakly in order to modify the current density locally in the vacuum chamber or bell jar and consequently to bring about a more intense or less intense heating across the substrate or the heating material. <IMAGE>

Title: Current detector of ac servo driver
Inventor: YAMAMOTO SUMIO
IPC: H02M7/48
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To improve the control performance of a motor by generating a voltage that is proportional to a current value from an inverter that is subjected to current control based on a current command value and amplifying and ADD- converting a voltage value with a variable amplification rate according to the current command value. SOLUTION: A three-phase current generated by an inverter 1 is supplied to an AC servo motor 3 for drive control. The U phase current is detected by a current detector 2 and is inputted to an operational amplifier 4, and a detection voltage is amplified and is outputted to an A/D converter 5 and is processed as current detection data. When a current command value is large, a switch 6 is tuned on by the output of a comparator 7 for short-circuiting a feedback resistor R3, and the amplification rate of the operational amplifier 4 is reduced by R2/R1, thus detecting a large current. When a current command value is small, the switch 6 is turned off by the output of the comparator 7 and the feedback resistor R3 is inserted and then the amplification rate of the operational amplifier 4 increases by (R2+R3)/R1.  Therefore, by suppressing a current detection resolution, vibration can be suppressed when the motor stops.
