Title: Torque adjusting mechanism for electric tool
Inventor: UEDA TAKASHI
IPC: B25B23/157
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To realize the secure drill mode while eliminating a cause of accumulated tolerance and deformation of each part by providing a holding plate, which is formed with a space for passing a ball to be energized to a claw side at a part thereof corresponding to a through hole of a gear case, freely to be rotated in relation to the gear case. SOLUTION: When a clutch is not operated, a cap 20 is rotated at constant or more so that a claw part 24 projected from a turning member 11 is brought into slide contact with a claw part 25 arranged in the cap 20. The turning member 11 is rotated while resisting the energizing force of a spring 23, and positional relation of each through hole drilled in a gear case 15 and in the turning member 11 is set so that axes thereof are displaced from each other. Even if a large load is applied to an output shaft 21, since a ball 14 to be engaged with a claw part 13 arranged in an internal gear 12 abuts on an end surface of the gear case 15 and the ball 14 can not moved in the axial direction, the internal gear 12 is fixed independently of a spring 16 and a clutch plate 19 so that the clutch can not be operated. Namely, drill mode can be set.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a motor driving circuit which is suitable for low consumption of power in an equipment such as a headphone stereo which is provided with a sensorless motor. SOLUTION: In a sensorless motor driving circuit which rotates a rotor by switching currents in armature windings 6, 7, 8, induced voltages Eu, Ev, Ew which are generated in the armature windings 6, 7, 8 due to rotation of a sensorless motor are compared with a reference voltage 19 by comparators 16, 17, 18. By letting transistors 20, 21, 22 conduct according to the output signals Su, Sv, Sw of the comparators 16, 17, 18, current is prevented from being supplied to a current amplifier circuit 4 from a voltage/current converting circuit 3 during a period when the armature windings 6, 7, 8 do not conduct. By this method, unnecessary current in the armature windings 6, 7, 8 is eliminated and acoustic noise and spike noise are suppressed and low consumption of power is accomplished.

Title: Control method and image forming device
Inventor: SUZUKI TAKEHIKO
IPC: G03G15/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To quickly settle a current to a target current value even against sudden load fluctuation by making a voltage range variable according to a detected current value. SOLUTION: When a constant-current control starts and a voltage is applied to a body 200 to be impressed on, the current value flowing through it is detected by a current detecting means 220, and converted into an analog signal to be inputted to a CPU 230. The current detecting means 220 for detecting the current made to flow therethrough is connected with a constant-voltage power source 210 for impressing a voltage, and the constant-current is achieved by controlling the constant-voltage power source 210 via the CPU 230 so that the current becomes a specified value. And, the control is carried out by preparing plural voltage variation steps beforehand here and changing over the voltage variation steps according to a differential current value of the present current value detected by the target current value and the current detecting means 220.  When the present current value deviates from the target current value, the current is corrected by a wider voltage variation step, and when the current is near the target current value, it is corrected by a small voltage variation range.

Title: Target tracking apparatus
Inventor: TAMAI KAZUKI
IPC: G01S13/66
Filed: 1990-02-22
Abstract: PURPOSE:To accurately detect a plurality of targets by making an averaging cell blank on the basis of an estimate position and an estimate error when the estimate position of the target corresponds to the averaging cell of a constant false alarm rate (CFAR). CONSTITUTION:A target tracking apparatus 6 calculates the estimate position and estimate error to the target A2 high in a level among two targets A1, A2. When the estimate position data corresponds to the averaging cells 211 (or 212, and so forth) of a CFAR circuit 20, five cells of the cells 211 are changed over to a blank state on the basis of the estimate position and the estimate error. By this constitution, since no output is taken out of five cells 5, the threshold level L1 to the other target A1 becomes low and the target A1 can be certainly detected without being affected by the target A2. At this time, since the detection probability of the target lowers generally when the number M of the cells 211 is smaller than a predetermined number, the outputs of the cells 211 are controlled so as to be supplied to an adder 151 by the number of the cells brought to the blank state in order to secure the number M and the lowering of detection probability is prevented.

Title: Data processor
Inventor: SATO KENYA
IPC: G06F15/16
Filed: 1990-02-22
Abstract: PURPOSE:To enable a processor set at the reception side to return from a runaway state when a FIFO type memory has a malfunction by providing a 1st processor, a type detection means, a FIFO type memory, and a 2nd processor. CONSTITUTION:A 1st processor 11 sends the address signals different for each type of the transfer information to an address bus AD and the transfer informa tion to a data bus 14 respectively. A type detection means 15 produces a signal showing the type of the transfer information from an address signal and outputs this produced signal. The transfer information and the signal showing the type of the transfer information correspond to each other and are stored in a FIFO type memory 13 and then applied to a 2nd processor 12. Therefore, the processor 12 can also recognize the type of the received information. Thus, it is possible to return the processor 12 to a normal working state from a runaway state even though the memory 13 has a malfunction as long as the data processing operation of the processor 12 is discontinued and the received information is skipped before reception of the next command.

Similarly, a test of branch addresses and a mechanism test of an address conversion table can be conducted.
