Title: Stop position controller for recorder
Inventor: TANABE TAKAYUKI
IPC: G03G15/04
Filed: 1988-05-25
Abstract: PURPOSE:To precisely bring an optical system to a prescribed stop position by detecting a previous stop distance in scanning operation, comparing the distance with the reference value of the stop position and correcting a brake start position according to the difference. CONSTITUTION:According to magnification, a reference stop position and the brake start position vary. When the optical system goes out, an arithmetic processor 45 detects a distance up to the reference position with the aid of a reference position detecting means 155, compares it with the distance of the reference stop position stored in a position storing means 715, and corrects the brake start position according to the difference. Namely, the difference between a counted value at the time of scanning, which is predetermined at the time of interruption arising when a resist sensor is turned off, and a value counted from the reference position to the brake start position is corrected, and a value counted at the end of scanning is added to the corrected value through the interruption of a reversed signal. When a value counted by an encoder reaches the added value, a brake start control signal is outputted. Thus, the optical system can be correctly stopped at a prescribed location.

Title: Circuit-board inspecting method
Inventor: FUJISAWA MASAYUKI
IPC: G01R31/28
Filed: 1988-05-27
Abstract: PURPOSE:To make it possible to detect the presence or absence of bridges and the like without increasing the entire test steps, by automatically forming test steps between specified pins when the pattern impedance of a circuit board is less than a specified comparison value, and performing measurement. CONSTITUTION:A comparison-value (k) setting means 17 sets the minimum impedance value (k) for comparison. A measuring means 18 for parts between one and all other pins deletes the test steps between one pin and all other pins in this pattern when the measured pattern impedance of a manufactured board is less than (k). A pin-measurement forming means 19 automatically forms test steps between specified pins in place of the deleted steps. A unit operating means 20 changes a scanner in correspondence with the newly formed test steps between the specified pins and adds a measuring signal to the pattern. At the same time, a response current is inputted into an amplifier. The measured data are compared with the data of a good board. When the value of the comparison is out of the allowable difference range, the presence of a solder bridge is judged. When the value is within the range, it is judged that the board is normal. Thus, the accurate board inspection can be performed.

That is, lastly, a capacitor C is electrically discharged at Do=H state and after this state, it is waited for 0.1 second, the electrical discharging is checked by a state in which Do changes from L to H and then a time in which the capacitor C changes from O to H is read as a timer setting time Tx. A micro-com puter may calculate Tx/To in reference to a reference time To and a timer setting time Tx and further calculate the combustion step in reference to a result of this calculation. With such an arrangement, it is possible to set an optional electrical energization.
