Title: Control device for driving system
Inventor: TOJO NAOTO
IPC: B25J13/00
Filed: 1988-12-14
Abstract: PURPOSE:To improve the adaptability of a driving system by providing the control device with a feedback mechanism, a gain setting means and a gain correcting means. CONSTITUTION:An error arithmetic part 28 compares data from an objective joint angle generator 10 with a practical joint angle and a feedback gain setting part 29 multiplies the output of the operation part 28 by a factor K2 to drive a motor 32 through a D/A converter 30 and a servo amplifier 31. The motor 32 rotates a joint and its rotational frequency is counted by an encoder 33 and held in a counter 34. The held rotational frequency is applied to the error operation part 28. An F/V converter 35 receives the output of the encoder 33 and feeds back the output to the servo amplifier 31. A gain correcting means 36 compares the count value of the counter 34 with the output of the generator 10 and corrects the factor K2 so as to reduce a shear from practical operation. A feedback gain setting part 37 multiplies a signal from an objective joint angle speed generator 16 by a feedback factor K1 and applies the multiplied value to the D/A converter 30. Since feedback gain can be changed to an always proper value by repeating said operation, the control of the driving system always matched with a purpose can be attained and the device can flexibly correspond to a change in operation characteristics.

Title: Implantable cardioverter defibrillator
Inventor: JIEIMUSU DEII KOOJII ZA SAADO
IPC: A61N1/362
Filed: 1993-11-24
Abstract: PURPOSE: To reduce time necessary to receive a high energy shock, when a first stepped treatment does not terminate tachycardiac arrhythmia b immediately conducting a second stepped treatment without any necessity of waiting for charging a capacitor of high voltage output. CONSTITUTION: When an output capacitor expects a third stepped treatment, the capacitor is charged again immediately after impressing a cardioversion pulse 84 [i.e., staring from a time point (tq)]. Accordingly, the result of the second stepped treatment as shown by a test result block 86 is examined when a time lag (tp) is completed during the charging of the output capacitor. In this way, confirmation of the second stepped treatment proceeds simultaneously together with the charging of the capacitor. As a result, immediately after the output capacitor is charged, the third stepped treatment (i.e., impression of a high energy pulse 88) can generate at the time point (t10).

Filed: 1987-12-17
Abstract: PURPOSE:To attain binarization processing with high picture quality by using a background cut level close to a background level, slicing a picture signal in preceding over a blur correction processing, and eliminating noise at the background level. CONSTITUTION:An image sensor 20 consists of a CCD line sensor or a CCD area sensor, is driven by a pulse supplied from a pulse circuit and outputs a time serial picture signal (a). The picture signal (a) is given to a background noise cut circuit 22, where the noise included in the background area is eliminated.

Title: Thermal fixing controller for electrophotogrraphic process and thermal fixing control method
Inventor: HIKICHI HIROBUMI
IPC: G03G15/20
Filed: 1991-12-02
Abstract: PURPOSE:To improve a fixing rate at the time of start up by control so that the temperature of a heating source for a thermal fixing unit reaches an initial fixing possible temperature higher than a normal fixing possible temperature at which fixing to a recording form can be attained, when the heating source for the thermal fixing unit is started up. CONSTITUTION:When it is judged that it is just after the heating source for the thermal fixing unit 10 has a start-up instruction, a temperature control part 50 controls the temperature of the heating source for the thermal fixing unit 10, on a target of the initial fixing possible temperature higher than the fixing possible temperature, and gives recording permission to a recording part 30 when a period dependent recording permission part 40 judges that the temperature reaches the initial fixing possible temperature. At this time, the initial fixing possible temperature is set higher than the normal fixing possible temperature, to make temperature gradient large to rapidly transmit heat to the whole of a heating roller, because the heat is not transmitted to the whole of the heating roller being the traveling system of the recording form when the heating source for the thermal fixing unit 10 is started up. Thus, a thermal fixing rate is increased, and toner is prevented from being peeled after the toner is fixed, as well.
