Title: Image forming device
Inventor: TSUCHIYA TAKAHIRO
IPC: G03G21/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To correctly detect a developer-empty state regardlessly of the developer capacity of each strong part and to reduce the number of components, by detecting the amount of developer that each developer carrying means has carried, and outputting a developer-empty-state signal when the total of the amounts that the developer has been carried reaches a value equal to or higher than a preset value. SOLUTION: The carrying screw 431Y, etc., are rotated by driving and rotating a carrying-screw gear 432Y, etc., so that the developers in the corresponding developer-storing means are added to corresponding developing units. The numbers of rotations of the carrying screw 431Y, etc., which coincide the exhaustion of the developers in the corresponding developer-storing means are set in advance, and the rotations of the carrying screws 431Y, etc., which are actually operated are counted. This prevents variations between machines and makes it possible to detect accurately amounts of remaining developers. The particular count-numbers of the carrying screws 431Y, etc., which are set for corresponding colors can be determined based on amounts of developers carried each time the carrying screws 432Y, etc., each make one rotation and amounts of developers stored in corresponding cartridges.

Abstract: PURPOSE:To easily set up an inclination at player's feet, by a structure wherein a pedestal, on which a player swings a golf club, is supported by a plurality of lifting means, each of which is independently controlled, and after a starting order is issued, the pedestal is being continuously altered at different inclinations until a stopping order is issued. CONSTITUTION:When a player being in training steps on a pedestal 1 and issues a starting order by operating a foot switch 6, it is determined in a control circuit whether the pedestal 1 is in a horizontal state or not. If the pedestal 1 is not in the horizontal state, lifting devices 2 composed of a plurality of telescopic legs 2a, e.g. 3 legs, each are driven by driving means 2b, and the length of each of the legs 2a is altered and thus the pedestal 1 is set up in the horizontal state. After that, each of the legs 2a is extended or retracted according to programmed control under which a program is previously set so that the devices can form different inclinations, and the inclination of the pedestal 1 is continuously altered. The player issues a stopping order by operating the foot switch 6 when the pedestal 1 inclines at a desired state of the player during this movement. At that time, the lifting means is composed so as to stop at that position and to fix the inclination of the pedestal 1 in that state.

Abstract: PURPOSE:To control a speed change of a motor to an S shape in an arbitrary range by so arbitrarily setting an acceleration and a time at polygonal lines that an acceleration during a period reaching a designated speed from a present speed becomes an S-shaped speed change approximated by a polygonal line. CONSTITUTION:A present speed set by a speed setter 1 is started to be changed with a speed change starting speed as S0, an acceleration value Ac1 of a head number stored in a ROM 4 is read and speed-changed by a CPU 3. A changed speed DELTAV1 of this zone is stored in a predetermined area of a RAM 5, and a real speed of a motor 8 is monitored with S1=(S0+DELTAV1) as next changing acceleration point. When the motor 8 is accelerated and the fact that an output of a speed detector 9 reaches a speed S1 is detected by a speed deviation detector 6, an acceleration Ac2 of next number is read from the ROM 4, and the acceleration is altered. Thus, the acceleration is so sequentially controlled as to become an S-shaped speed change approximated by a polygonal line, and the speed of the motor 8 is controlled.

Title: Withstand voltage tester
Inventor: SUZUKI MAKOTO
IPC: G01R31/12
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To easily discriminate a partial discharge phenomenon generated at an abnormal part by applying adequate voltage to a tested object. SOLUTION: Voltage is applied to a tested object through a single-phase variable transformer, a boost transformer, a charge-discharge current limiting circuit and a discharge detecting part. In the case of a coil of the tested object is damaged and brought into contact with a core, upon detecting the flow of a relatively large current to the discharge detecting part without generating partial discharge, voltage applied to the tested object is cut off. In the case of the coil of the tested object being in contact with the core without being damaged, partial discharge is generated at a contact part, and a micro partial discharge current flows to the discharge detecting part. This current and a signal of a noise detecting part are amplified by a differential amplifying part, and a partial discharge signal is extracted.  Since the charge-discharge cycle of partial discharge is within a fixed range, abnormality of the tested object can be discriminated by measuring the partial discharge signal through a band- pass filter.
