Title: Capacitor type spot welding machine
Inventor: NEO SHIGERU
IPC: B23K11/26
Filed: 1990-06-27
Abstract: PURPOSE:To prevent the reverse voltage from being impressed on a capacitor by providing a switching element having self-extinction of arc of a transistor, etc., in parallel with a switching element having nonself-arc-extinguishing characteristics for discharge. CONSTITUTION:When the voltage on both ends of the capacitor 4 attains almost zero, since the switching element having the self-extinction of arc is turned on for a short period of time, the switching element having nonself-arc- extinguishing characteristics for discharge is made to less than a holding current and turned off. At this time, exciting energy of a transformer 6 for welding flows through a path of a resetting means and continues for a short period of time till the exciting energy is extinguished. Accordingly, the exciting energy of the transformer 6 for welding is extinguished quietly and a magnetic core can be reset and the switching element is turned off, hence the reverse voltage is not impressed at all on the capacitor 4.

Title: Differential amplifier
Inventor: KUSAKABE HIROMI
IPC: H03F3/45
Filed: 1982-09-29
Abstract: PURPOSE:To obtain driving current to be applied to the succeeding amplifier sufficiently by inserting resistors between the bases of two transistors (TR) and between the base and collectors of these TRs respectively. CONSTITUTION:A resistor R3 is inserted between an intermediate point connecting the base of a TR Q3 with a resistor R1 and an intermediate point connecting the base of a TR Q4 and a resistor R2. In a differential amplifier having said constitution, a difference is generated between respective operating current of the TRs Q3, Q4 because of voltage drop due to current id flowing into the resistor R3. The generation of the difference acts as negative feedback so that the current id is reduced. Therefore, respective operating current I5, -I6 of TRs Q5, Q6 are made to flow as shown in the figure and differential current (output current) Id is made to flow as shown by the dotted line. Consequently, sufficient output current can be obtained at the input of a large signal without deteriorating a linear property also at the input of a small signal.

Filed: 1989-06-30
Abstract: PURPOSE:To simplify recognize the parts where the trimming and masking processes are carried out by deciding the head property and the continuity of a marker line related to the plane of an original based on the mutual relationship between the 1-dimensional marker lines of each scanning line and detecting an area enclosed by a 2-dimensional marker line. CONSTITUTION:The read data on an original image is binarized with two different threshold values by a binarizing process means 1 and stored in a memory 2. Then a 1st detection means which is embodied by a process program stored previously in a memory of a central control part 10 detects the start and end points of a marker line for each line out of the data stored in the memory 2. Thus a 1-dimensional marker line related to each scanning line is detected. Then a 2nd detection means decides the head property and the continuity of the marker line related to the plane of an original based on the mutual relationship between the 1-dimensional marker lines. Then an area enclosed by a 2-dimensional marker line is detected. As a result, the parts where the trimming and masking processes are carried out can be easily detected out of the original image just by enclosing these parts with the marker lines of neutral tints.
