Title: Method for attaching spacer for multiple conductors
Inventor: IWAKI TSUNEMASA
IPC: H02G1/02
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for attaching a spacer for multiple conductors which requires no correction by a worker on board a pendent cage after the attachment. SOLUTION: When intending to attach a spacer onto multiple electric wires 10 stringed with a space to a vertical direction, the computed value of the catenary angle θ0 of the electric wires at attaching positions of each spacer is obtained based on a slackness calculating formula. When the spacer is attached onto the electric wires with a pendent cage 7, the actual catenary angle θ of the electric wires at attaching positions of the spacer is measured. Then, the spacer is attached onto each electric wire by shifting the attaching position P13 on the bottom wire 13a by a corrected amount R (to an attaching position Pb) obtained by a calculating formula R = Dtan (θ-θ0 (where D is the space from the top to bottom wires) against the right angle attaching position to the top wire 11a.

Title: Backup power source circuit
Inventor: MUKAI SHINJI
IPC: H02J9/06
Filed: 1988-04-08
Abstract: PURPOSE:To supply constant and sufficient driving force to a load when a source compensation capacitor is discharging, by connecting a semiconductor element which is blocked in reverse bias when the capacitor is charged while conducted in forward bias when the capacitor is discharged in parallel with a resistor which is conducted when the capacitor is discharged. CONSTITUTION:Since a transistor(Tr)6 is normally blocked with reverse bias, driving power is fed from a power source 1 through a terminal 2 to a microcomputer and a capacitor(C)3 is charged through a charge resistor 4. When power supply from the power source 1 is interrupted, forward bias is applied onto the Tr6 through the discharge voltage of C3 to conductor Tr6, and power is discharged from C3 through Tr6 to the source input terminal 2 of the microcomputer thus backing up the microcomputer. Since the voltage of C3 is simply subjected to forward voltage drop of Tr6, sufficient driving force can be applied onto the microcomputer.

CONSTITUTION:When holding a mask 10 as well as a mask stage 11 which can be moved up and down and a wafer 9 and performing exposure transfer with a wafer stage 16 which can be moved in XY direction, the wafer stage 16 is moved while the mask stage 11 in a stop state and relative positioning between the mask 10 and the wafer 9 is performed.
