Title: Method of measuring working clearance length of powder contamination type discharge working machine
Inventor: KITAGAWA KOJI
IPC: B23H1/02
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To measure the working clearance length independently of the specific gravity of the powder and change of the specific gravity of the working liquid by computing the working clearance length on the basis of the relation between the discharge possible range obtained on the basis of the axis position at the time of starting discharge and the axis position when the discharge is stabilized and the previously measured discharge possible range and the working clearance length. SOLUTION: A clearance control 9 section is a controller for driving a position control motor 12 on the basis of the mean voltage 13 constantly holds the discharge pulse density and the working clearance length. The clearance control section 9 monitors the electrode position so as to always output the signal for showing the axis position to a gap computing section 10. The gap computing section 10 computes a difference between the axis position at the time of starting the discharge just after jumping and the axis position when the discharge is stabilized so as to measure the discharge possible range, and obtains the working clearance length 14 of a clearance with a reference of a data memory section 11 for storing the relation between the discharge possible range previously obtained by experiments and the working clearance length 14.

Title: Frame sending count preventive mechanism
Inventor: DANIERU MAIKERU PAGANO
IPC: G03B17/36
Filed: 1990-05-09
Abstract: PURPOSE: To prevent a film frame feeding count pawl from erroneously engaging with a take-up perforation in the leader part of a film strip by providing a specific film detecting member. CONSTITUTION: When the front end part 37 of the film strip F is moved over the end part flange 137 of a film detecting lever 135, the film-end part moves the lever 135 from a preparation position to a detecting position by the actuation of a cam. Consequently, a holding stud 147 for the detecting lever 135 is moved, and a spring 145 pivotally rotates the frame feeding count pawl 125 from a retreat position to the preparation position. When the frame feeding count pawl 125 is moved to the preparation position, the take-up perforation T of the leader part L has already been fed from the engaging range of the end part tooth 127 of the pawl, to complete passing. Thus, the end part tooth 127 of the pawl is prevented from erroneously engaging with the leader part L, in one of the take-up perforation T of the leader part L.

Filed: 1987-05-15
Abstract: PURPOSE:To automatically calculate the coordinate value on a curve by changing the value of the variable for the curve of a numerical formula using a variable and calculating repetitively said variable value. CONSTITUTION:A curve defining system for numerical control comprises a data input device 101, a data analyzing part 102, a variable analyzing part 103, a calculating part 104, a control part 105, and a data output device 106. The data are supplied from the device 101 and the part 102 checks the presence or absence of a control command. Then a control command if confirmed is transferred to the part 105. If not control command is confirmed, it is checked whether a variable is included in the data or not. If so, the detected variable is given to the part 103 and the presence or absence of a data sentence is checked. The part 105 decides a conditional formula of the control instruction and acquires a pointer for the necessary data to inform it to the device 101. If it is decided that a data sentence utilized the value of said variable, the data is read out of an internal memory in response to the variable number and replaced with a variable. This variable is returned to the part 102. Thus the NC data is produced.
