Title: Method of coupling pipe
Inventor: HAINTSU UNEBUITSUSE
IPC: F16L13/16
Filed: 1991-04-12
Abstract: PURPOSE: To tightly connect pipes while maintaining the predetermined pushing posture by loosening the operation for closing a clamp for fastening a press pipe joint after this force exceeds a limit value previously set freely to be adjusted. CONSTITUTION: A regulated pushing posture is controlled independently of human being so that the operation for closing a clamp for pressing a press pipe joint 1 is loosened after the force 7 applied in a direction of forcible deformation exceeds a preset limit value Ks. The force 7 applied to a pipe 5 is deforming the pipe 5 more in the axial direction, but a stopper 4 hinders this deformation. As a result, the force 7 rises with a steep incline concerned with a numerical value as it is expressed as a force transition line 10 in outline, and when the force 7 achieves the preset limit value Ks, lock of the operation for closing a clamp of a press tool is released so as to fasten the clamp.

Title: Buckle for vehicle safety belt system
Inventor: FURANTSU UIAA
IPC: A44B11/25
Filed: 1993-05-11
Abstract: PURPOSE: To provide a buckle for a vehicle safety belt system having a lock mechanism controlled by inertia, and which can be readily integrated with an existing buckle, providing a high safety limit and dispensing with a playing stroke of a release button. CONSTITUTION: This buckle for a safety belt device provided with a preliminary tension device engages with the preliminary tension device and is prevented by a lock claw 42 from opening contrary to an intention at the beginning and ending of a preliminary tension stroke. At the beginning of the preliminary tension stroke, an inertial field 56 moves the lock claw 42 to a lock position by a mass inertial effect and prevents a release button 30 from moving in the preliminary tension direction R relative to a base. Since the center of gravity C explores a predetermined relative position with respect to the position 44 of the device of the lock claw 42, the lock claw 42 stays at the lock position at the end of the preliminary tension stroke and comes off the inertial field 56.

Title: Controller of motor
Inventor: ISHIKAWA YOSHIO
IPC: H02P29/00
Filed: 1984-05-31
Abstract: PURPOSE:To prevent a motor current from overflowing by slightly smoothing the rise of a current command near saturation. CONSTITUTION:An operational amplifier 11 adds a speed command voltage Vref and a feedback voltage Vfb, and outputs a current command VIref. The command Vrref output from the amplifier 11 is input through a differentiator 22 having a parallel circuit of a resistor and a capacitor to an operational amplifier 21. The amplifier 21 turns ON a diode 24 connected with an output terminal when the command VIref increases from the voltage VIc of a setter 13, applies a limit signal Vce to the amplifier 11 to suppress the command VIref. Thus, the current flowed to the motor can be controlled without overflowing.

Title: Electric cleaner
Inventor: NOGUCHI YOSHIHIRO
IPC: A47L9/28
Filed: 1990-04-25
Abstract: PURPOSE:To suppress operating noise, stop a blower at the time of reaching a temperature killing ticks, and kill the ticks by connecting a hose to the exhaust hole of a cleaner body, circulating the air to heat the air by the blower, and operating the blower in the state lower than the maximum output. CONSTITUTION:When a hand pipe 4 is installed to the exhaust hole 12E of a second case, an electric changeover switch 9 makes contact with the side (b) to send a current between a thermostat 10 and a blower motor 9, and the air is circulated to raise the air temperature to the temperature killing ticks of 50 deg.C. When it reaches the killing temperature, the thermostat 10 is released, and the blower motor 8 is stopped, while the inner temperature of cases 11, 12 keeps the killing temperature for a time sufficient to kill the ticks, perfectly killing the ticks. As the high output blower motor 8 is operated at low output by the function of the changeover switch 9 and a fixed resistance R2, the operation noise is lowered, and the operation instability and, forcedly, risk due to the temperature rise rate difference between the circulating air temperature and a motor coil at the time of high output operation are eliminated, and safety is improved.

Title: Deflection amplifier
Inventor: TAKAHAGI SHUNICHI
IPC: G09G1/04
Filed: 1988-05-02
Abstract: PURPOSE:To perform numerous deflections continuously or an abrupt deflection by causing boosting coils to accumulate energy. CONSTITUTION:The 1st boosting coil 1 for generating a high voltage to be applied across the 1st drive circuit from a DC power source 18, the 2nd boosting coil 2 for generating a high voltage to be applied across the 2nd drive circuit, and a current control circuit 4 which makes the sum of the 1st deflecting current I+ and 2nd deflecting current I- almost constant are provided. Since the two boosting coils 1 and 2 are used in such way, charging and discharging of energy alternately occur in the boosting coils 1 and 2 even when abrupt changes in deflecting signals take place numerous times. Thus an abrupt deflection can be performed even when the deflection signals abruptly change.

Abstract: PURPOSE:To decrease roughness on a metal surface by a method wherein the crystal grain diameter is made smaller and uniform through the provision of a thin oxide or nitride film within a two-layer metal thin film formed on a substrate. CONSTITUTION:A ground pattern 3 is built by subjecting to patterning for example a silicon oxide film formed on an insulating layer 2 covering a semiconductor substrate 1. A part of the ground pattern 3 serves as a positioning pattern 3a. An aluminum thin film 4 is attached thereto by sputtering evaporation. The aluminum thin film 4 consists of two layers 6, 7 of the like thickness and an extremely thin aluminum oxide film 5 is sandwiched between the two layers 6, 7. In this structure, the aluminum oxide film 5 splits crystals constituting the aluminum thin film 4 into two thicknesses. Consequently, the diameter of crystals 6a, 7a in the aluminum layers 6, 7 can be decreased. With the grains being smaller and uniform in the aluminum thin film 4, the roughness on its surface may be reduced.
