Title: Press head structure for solder press
Inventor: TANIKADO MITSUO
IPC: H05K3/34
Filed: 1989-10-18
Abstract: PURPOSE:To reduce stress resultant from external stress which is applied to a printed board to locate a flat surface of solder during press work by installing a heat generation source to a press head to generate heat which is lower than a melting temperature of solder to be pressed. CONSTITUTION:A heater 5 and a temperature sensor 7 are installed to a press head 2. Pads formed on a printed board 4 are coated with presolder. After the press head 2 of a solder press device 1 is positioned, a heater 5 installed to the press head 2 is arranged to heat by manipulating a temperature controller 8 so as to obtain a temperature lower than the melting temperature of solder under control. A surface treatment is carried out by placing the press head 2 into contact with the pads intended for a specified time, which softens the solder. This construction makes it possible to reduce external stress required to press and relieve destructive stress exerted to the printed board and hence improve reliability.

Inventor: TADA TATSUO
IPC: H01R13/64
Filed: 1994-11-02
Abstract: PURPOSE: To provide at low cost a structure for determining whether or not the connected state of connectors is good.

Abstract: PURPOSE:To make smaller the locus of a switching transistor(TR) and to make it difficult to destroy by composing a driving signal to drive a switching power source so as to be supplied to the switching power source after the passage of a prescribed time. CONSTITUTION:When an output voltage is set at V1, driving signal generating circuits 3 and 4 provide functions which output the driving signals when their reset terminal values are at >=V1/2, and do not output the driving signals when the values are lower than V1/2. When the voltage V1 is outputted from a power source 5, since the reset terminal of the driving signal generating circuit 3 inputs a resistance R1 and the integration voltage of a capacitor C1 of the integrating circuit of the capacitor C1, the voltage of the reset terminal is at >=V1/2 after the time determined by the resistance R1 and the time constant of the capacitor C1, and the driving signal is outputted. Thus, the locus of a switching TR TR1 is made smaller, and it is made difficult to destroy.

Filed: 1984-12-21
Abstract: PURPOSE:To continue steering control of a submarine boat even if a course, depth or attitude angle sensor are at fault, by calculating the present course, depth and attitude angle of the submarine boat by solving an equation motion. CONSTITUTION:A motion equation calculating part 3 solves and equation of motion by a prescribed algorithm from a signal for indicating a longitudinal steering angle Br, a front steering angle Bef and a rear steering angle Bea outputted from a steering angle control part 2, and a speed signal (v) outputted from a speed detecting part 7, calculates the present course, depth and attitude angle of a submarine boat, and outputs them as signals phi', h' and theta', respectively. For instance, when the course sensor is at fault, an output phi' of the motion equation calculating part 3 is outputted instead of an output phi of a sensor part 6. Accordingly, the steering angle control part 2 can continue control of a helm driving part 8 by executing control operation so that the output phi' of the motion equation calculating part 3, and outputs (h), theta of the sensor part 6 attain a target value indicated from a target setting part 1, respectively. Even in case the depth sensor or the attitude angle sensor, etc. are at fault, the steering control is continued by using the output of the motion equation calculating 3 in the same way.

Title: Processing device of signal output from sensor provided with differential response characteristic
Inventor: YUUMIYURIAN GUREGOWAARU
IPC: G01R19/00
Filed: 1991-09-21
Abstract: PURPOSE: To obtain a sensibility almost equal to the sensibility of an active sense by integrating a signal from a frequency higher than a prescribed frequency, amplifying and integrating the signal between the frequencies. CONSTITUTION: A standard passive sensor (differential sensor) 10 is connected to the load 12 of a value Rc through the cable 11 of an impedance Rc . The received signal is processed by a device 22 provided with an integration means 20 and a correction means 21. An integration means 20 is especially constituted of a reduction-type cell R2 C2 . In such a case, it often occurs that a time constant τ2 equal to R2 C2 is considerably smaller than a conventional time constant τ1 , and therefore an expression f2 = 1/(2πR2 C2 )}>>f1 is realized. The sensibility of the device becomes larger by f2 /f1 times, a low cut off frequency becomes from f1 to2 and the signal generated from the differential sensor 10 is not integrated by the frequency f1 as the result of integration from the frequency f2 larger than the frequency f1 .  Thus, the correction means 21 connected to the integration means 20 makes a specified response and the loss of the response with the low frequency is compensated.

Abstract: PURPOSE: To prevent the reverse transfer of foreign matter from a cleaning roller to an oil applying roller so as to prevent the deterioration of image quality by making a cleaning member to be touchable and detachable to and from the cleaning roller. CONSTITUTION: A cleaning member 7 is arranged so as to be free in moving back and forth against the peripheral surface of a cleaning roller 6, and the cleaning member 7 comes into contact with the cleaning roller 6 with a predetermined timing. When the feeler 202 of a toner detection sensor 200 is located at a solid line position, an operation piece 202C shields a photointerrupter 201 so as to be off and a control portion detects no foreign matter adhesion. When the diameter direction position of the peripheral surface of the cleaning roller 6 displaces in an outside diameter direction caused by the increase of a foreign matter thickness, the feeler 202 moves to a dotted line position and the operation piece 202C detaches from the photointerrupter 201 so as to be off.  Thereby, the control part judges that the increase of the foreign matter such as a toner and the like exceeds a permissible amount, and makes a cleaning solenoid turned on, and the cleaning member 7 presses the cleaning roller 6 to remove the stuck foreign matter.
