Title: Developer density controller
Inventor: SUZUKI AKIO
IPC: G03G15/08
Filed: 1981-02-18
Abstract: PURPOSE:To stabilize development effect and to hold it adequately for a long period by detecting the toner density of a developer and by exercising variable control over a level for detecting said toner density according to the density of a reference image formed on a photoreceptor. CONSTITUTION:The toner density of a developer 45 in a developing device 43 is detected by a magnetic permeability sensor 63, whose detection signal is inputted from a developer density detection part 67 to a CPU61. On the other hand, a control signal from the CPU61 causes a laser beam 17 from an A/O modulator 16 to illuminate a photosensitive drum 31, and the image density Dp of a developed reference image obtained by developing a reference latent image by the developer is detected by a reflection density detection part 143, whose detection signal is inputted to the CPU61. Then, the A/O modulator 16 is controlled to read background density Do on a photoreceptor surface 33 after the development, and on the basis of those density levels Dp and Do, a detection level for detecting the toner density is varied.

Title: Controller for induction motor
Inventor: AKIYAMA NAOMIKI
IPC: H02P27/08
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To protect a motor against burning even if an undue load is applied during a low speed operation while saving the operating energy by suppressing voltage ripples produced through PWM control of AC voltage being supplied to the motor upon elapsing a predetermined time under such a state as the speed detection value is lower than a specified level. SOLUTION: When a motor is operated under such a state as the line speed reference SPL is lower than a specified level and that state is sustained for a specified time or longer, a switch 21 outputs a voltage reference Vd2r selectively. The voltage reference Vd2r is set lower than a voltage reference Vd1r and the DC output voltage Vd from a converter is reduced to a level corresponding to the voltage reference Vd2r. Consequently, the DC supply voltage Vd to inverters 4, 4a is decreased and the modulation rate of PWM control is increased and thereby ripples of supply voltage to induction motors 5, 5a are suppressed. According to the arrangement, voltage loss in the induction motors 5, 5a can be reduced and the possibility of burning the induction motors 5, 5a can be reduced even if an undue load is applied during low speed operation.

Title: Hydrogen storage alloy secondary battery
Inventor: OYA KUNIYASU
IPC: H01M4/26
Filed: 1988-02-01
Abstract: PURPOSE:To increase high rate charge-discharge cycle life by adding cobalt particles whose mean particle size is 5-20mum and specific surface area is within a specified rage to a negative electrode. CONSTITUTION:Cobalt particles whose mean particle size is 5-20mum, and specific surface area is 1.0-2.0m<2>/g<-1> are added to a negative electrode 14. Since the cobalt particles added to the negative electrode 14 have large specific surface area and are covered with platinum or palladium, the catalytic action of cobalt particles is high and the oxygen absorbing capability of a negative electrode 14 in quick charging is high. High rate charge-discharge cycle life is increased.

IPC: B23Q17/09
Filed: 1983-02-12
Abstract: PURPOSE:To memorize in high approximate accuracy with a small capacity by a method wherein only the data of a peak point, the point of deflection and a point whereat the datum has exceeded the allowable value of change among the signals of the cutting load or the like, which are indicating the data changing at random in accordance with a time, are memoried. CONSTITUTION:The load data are sent to three sets of decision units 7, 8, 9 through a load data inputting unit 6. The decision unit 7 decides the peak point (d) indicating the load data, the decision unit 8 decides the points (a), (c), (d), (b) of deflection of a pattern indicating the load data and the decision unit 9 decides the point (b) whereat the pattern indicating the load data has exceeded the allowable value delta of change. A feature point decision unit 10 inputs the results of decisions of the decision units 7-9 and sends out a memory command to the memory unit 11 when either one of deciding conditions is satisfied. The memory unit 11 reads out from a load data inputting unit 6 by the memory command an memorizes it. Accordingly, a principal feature is memorized well even it is within the allowable value of change, therefore, the allowable value of change may be set at a large value and the predetermined memory may be effected with a small capacity.

IPC: F24F1/00
Filed: 1984-02-09
Abstract: PURPOSE:To restrict the width of diffusion of purified air by the effect of high- speed air stream blown out of a blow-off port face having small coefficient of ventilating resistance by arranging the blow-off port faces, having different coefficients of ventilating resistance, at a blow-off port. CONSTITUTION:The blow-off port 5 is constituted of a perforated plate face 10 and a slit face 11, whose ventilating resistance coefficient of air is smaller than the perforated plate face 10, and the slit face 11 is arranged at a side near a suction port 6. The air B, purified by a filter 3, is blown off into a room through the blow-off port 5. In this case, the ventilating resistance coefficient of air of the slit face 11 is smaller than the same coefficient of the perforated plate face 10, therefore high-speed and much amount of air is blown off through the slit face 11. A belt-like high-speed air stream D is generated between the suction face 6 and the perforated plate face 10, therefore, the low-speed purified air B, blown off through the perforated plate face 10, is not induced by the suction air A and, accordingly, the shortcircuit of the purified air B will never be caused.
