Title: Shake correcting device and camera
Inventor: KONISHI KAZUKI
IPC: G03B5/00
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To enable a correcting means to set the initial position suitable for respective cases when a large number of strokes are required/unrequired for correcting shake by making a driving method at the time of setting the correcting means in the initial position different in respective cases based on photometric output. SOLUTION: An MPU 1 reads the output of the photometry sensor 3. A correcting leans 6 is moved to the end part on one side by driving motors 9 and 11. When the movement is completed, the motors 9 and 11 are reversely driven at fixed speeds by specific amounts, to stop the correcting lens 6 at the initial stage position as the nearly center of a moving range. In such a case, when the photometric output is higher than a prescribed value (luminance for photographing is comparatively high and an exposure time is short), the correcting lens 6 is driven to the initial stage position in a comparatively short time (high speed), to be quickly set in the initial stage position. On the other hand, when comparatively low luminance is obtained, the correcting lens 6 is driven to the initial stage position in a comparatively long time (low speed), to be accurately set in the initial stage position.

Title: Method for controlling cutting out quantity of auxiliary raw material
Inventor: TSUURA ISAO
IPC: C21C5/28
Filed: 1990-06-01
Abstract: PURPOSE:To exactly control the cutting out quantity of auxiliary raw materials even if the estimated flow quantity varies by correcting the estimated flow quantity to be subtracted from a set value in accordance with the average value of the deviation between the actual value and set value of the control of the cutting out quantity of the auxiliary raw materials. CONSTITUTION:The auxiliary raw materials are cut out at a specified speed by a feeder to a weighing machine and a stop command is outputted to the feeder at the point of the time when the weighing value of the weighing machine coincides with a prescribed value. The value after the estimated flow quantity estimated to flow into the weighing machine after the outputting of the stop command to the above-mentioned feeder is subtracted from the set value for weighing is used as the above-mentioned set value at this time. The cutting out quantity of the auxiliary raw materials is so controlled so to be kept constant. The above-mentioned estimated flow quantity is corrected by the average value of the deviation between the above-mentioned actual weighing value and the set value when the above- mentioned deviation is above a certain threshold and the deviation arises several times in the same direction or the absolute value exceeds the absolute value of the previous time. The exact cutting out of the auxiliary raw materials is possible in this way even if the flow quantity fluctuates in accordance with various factors.

Title: Control of multiplexed current type inverter
Inventor: KOSAKA KENJI
IPC: H02M7/497
Filed: 1987-06-08
Abstract: PURPOSE:To reduce noise and torque ripple, by deviating the triangular wave carrier signal of a multiplexed current type inverter properly between unit inverters. CONSTITUTION:Current is duplicated by employing two unit inverters 1A, 1B, respective output terminals are connected directly and the current is supplied to a load or an AC motor 2. The half cycle of the output current of the unit inverters 1A, 1B is chopped so as to obtain a pulse type current so that the high frequency current of a low degree is reduced while the unit inverter 1B is operated with the delay of an electric angle 30 deg. with respect to the unit inverter 1A. When the chopping phase of the current is determined, the phase of a carrier signal, between employing triangular wave carrier signal and a saw-teeth type wave control signal, is deviated by 2pi/N between the unit inverters. According to this method, the composite output current is prevented from including the high frequency current of a high degree near a current chopping frequency, whereby noise, torque ripple and the like may be reduced.
