Inventor: TOKI AKIRA
IPC: G08B17/12
Filed: 1991-12-24
Abstract: PURPOSE:To increase an adjustable range of the sensitivity of a sensor while reducing time required for adjustment. CONSTITUTION:A variable timber 7 is so arranged that it starts operation with the first discharge of an ultraviolet detection tube 1 to output a reset signal to a variable counter 8 when a fixed time is reached. A variable counter 8 is so arranged that the frequency of the discharging is counted and a signal is sent to a switching circuit 6 when a fixed frequency of the counting is completed to activate a sensor. Here, the fixed time is varied according to modes of 'capacity of detecting ultraviolet rays with the ultraviolet detection tube 1' and 'variations in voltage loaded on the ultraviolet detection tube 1' of individual sensors to adjust the sensitivity as sensors. In short, the sensors with a lower capacity of detecting ultraviolet rays and those with a lower voltage loaded on the ultraviolet detection tube 1 is adjusted to extend the time. By the contrary, the sensors with a higher capacity or with a higher voltage applied are adjusted to shorten the time.

Abstract: PURPOSE:To perform accurate direction correction control by calculating the quantity of a position shift between the center of a magnetism generation device and a 1st magnetic head from angle formed of a traveling direction, a 2nd magnetic head and the center of the magnetism generation device. CONSTITUTION:When a perpendicular 21 on the same plane with the traveling direction P of the Y-axial magnetic head 22 moves to a position passing the center Q of the permanent magnet 1 while a self-traveling carriage 30 mounted with the Y-axial magnetic head 22 and XY-axial head 12 at an interval L travels in the traveling direction P, the quantity of the position shift between the center Q of the permanent magnet 1 and the Y axis 22 is calculated from M=Ltantheta, where theta is the angle formed of the traveling direction P, the XY- axial magnetic head 12, and the center of the permanent magnet 1. The angle thetais found from the intensity ratio of magnetic fields in a Y-axial direction and an X-axial direction, so even when the intensity of the permanent magnet 1 varies with time, the ratio does not vary. The position shift quantity M is therefore calculated with accuracy.

Abstract: PROBLEM TO BE SOLVED: To carry out flash photographing at a moment on the opportunity of photographing by raising voltage, carrying out charging, and charging a driving voltage at the time of starting photographing, and emitting flash light. SOLUTION: A primary voltage raising part 20 raises d.c. voltage supplied to an electric power supplying part 10 to high voltage. An energy charging part 30 is charged with the high voltage sent out of the primary voltage raising part 20. A photographing control apparatus sends out a voltage raising signal to a secondary voltage raising part 40 to supply voltage necessary to flash light emission. The secondary voltage raising part 40 secondarily raises voltage with which the charging part 30 is charged and sends out the resultant voltage. A charging capacitor C6 of a high voltage charging part 70 is charged with the sent out high voltage. High electromotive force is induced in a trigger part 50 by a trigger signal sent out of the photographing control apparatus and applied to a xenon discharge tube XE of the light emitting part 60.  Consequently, high voltage with which the charging capacitor C6 is charged is discharged and the xenon discharge tube XE emits flash light.
