Title: Dc-dc converter
Inventor: OOTA MORIO
IPC: H02H7/12
Filed: 1978-09-04
Abstract: PURPOSE: To enable opening or closing of the output of a ringing choke type converter in logic level by a simple control circuit configuration.  
     CONSTITUTION: When open or close signal is applied to switches S 1 , S 2 , gates 11, 12 are opened and main switching transistor 3 is conducted to start a DC-DC converter. Control voltage is operated to lower the potential at the point P via a resistor 16 at that time. When this potential becomes lower than threshold level, the gate 11 is closed to thereby quickly charge a capacitor 18 to thus maintain the operation of the converter. When malfunction occurs at the output, the control voltage is lowered to thereby raise the voltage at the point P. Thus, the gate 11 is opened to start discharging of the capacitor 18. When this state continues, the potential at the point Q becomes lower than the threshold level. Thus, the gate 11 is closed to conduct a control transistor 7 through a resistor 22 to thereby stop the operation of the converter.

Title: Package system
Inventor: TAKEKOSHI HIROSHI
IPC: G06F3/00
Filed: 1988-05-06
Abstract: PURPOSE:To avoid the superposition of noise onto a bus line when a hot line of a package is connected and disconnected by securing the switch control of a 3-state bus driver receiver set on a separate package between the high and low impedance states. CONSTITUTION:A main package 3 has a fault and must be replaced with the different one and other main packages 3'-3<n> can not be interrupted since the data are transferred among these packages. In such a case, a control signal is sent to a 3-state bus driver receiver 6 set on a separate package 4 set opposite to the faulty package 3 from a bus control console 8. Thus the receiver 6 is set at a high impedance. Thus a signal line of the package 3 can be electrically separated from a bus line 2. As a result, the hot line of the faulty package 3 can be connected and disconnected with no superposition of noise onto the line 2.
