Title: Conveying and driving controller for liquid developing device
Inventor: YAMANASHI MOTOAKI
IPC: G03G15/10
Filed: 1989-04-11
Abstract: PURPOSE:To obtain a driving controller for controlling the changing ratio of a motor torque and slowing down the conveying velocity variation of a subject to be driven and also capable of rapidly conveying by disposing an electric current value detecting means and a means for controlling the changing ratio of the electric current value. CONSTITUTION:The controller is provided with a resistor 102 and a differential amplifier 103 functioning as the electric current value detecting means, a differential unit 101 and an integrator 104 functioning as the changing ratio control means. In the detecting means, the torque outputted by a conveying motor 2 is detected by the electric current value to the motor 2. In the control means, the prescribed value of the electric current is changed and outputted on the basis of the detected value so as not to be rapidly changed. Thus, since the electric current value corresponds to the torque, the changing ratio of the torque by the motor 2 is controlled and the conveying velocity variation of the liquid developing device (toner tanks 21y, 21m and 21c) slows down. Then, the allowable maximum electric current can flow in the motor without necessitating the restriction on the magnitude of the torque itself and the prescribed quantity can be rapidly conveyed.

IPC: B23H7/02
Filed: 1988-04-14
Abstract: PURPOSE:To prevent a lower arm from being exerted the force from a seal mechanism to avoid the deformation of the lower arm for improving the accuracy of positioning by providing a driving force transmitting means for moving a seal plate in the moving direction of the lower arm. CONSTITUTION:A bellows 5 seals the through hole opening 11-1 of a seal plate 11 so as to prevent machining liquid from leaking, and the seal plate 11 seals the side face of a machining bath 1 or the opening section 1-2 of the rear face to avoid the leaking of machining liquid. When the moving direction of the lower arm 6 inserted into the through hole opening 11-1 is detected by the detecting means 15 and 16 fixed to the seal plate 11, the motor 7 fixed to the outer wall of the machining bath 1 is rotated in the normal or reverse direction according to the detected signal. The torque of the motor is transmitted to the seal plate 11 through a drive force transmitting means 10 to move the seal plate in the same direction as that of the lower arm 6. This prevents the side face of the lower arm 6 from abutting the edge of the through hole opening 11-1 of the seal plate 11 and avoids the exertion of the force from the seal plate 11 to the side face of the lower arm 6.

Title: Liquid cosmetics vessel having brush
Inventor: OGAWA HIDEKAZU
IPC: A45D34/04
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To supply liquid cosmetics to a brush even if a residual quantity of the cosmetics decreases by installing a long bar weight extending in a main body by loosely inserting a through hole of a plug into a brush holder internally inserted so as to be vertically movable. SOLUTION: When a top and the bottom of a vessel main body 1 are reversed, liquid cosmetics K flow by following a movement of a bar weight 5, and is sucked in from a clearance between a through hole 41 of a plug 4 and a peripheral surface of the bar weight 5, and is flowed and filled in a cylindrical passage A. When the main body 1 is inversely returned after use, since mass of the bar weight 5 is large, a brush holder 3 is moved up to a closing position where the lower end comes into contact with the plug 4. Surplus viscous cosmetics in the cylindrical passage A also smoothly returns in a vessel from a clearance between the through hole 41 and the bar weight 5 by slipping-out operation of the bar weight 5 from the plug 4.  Since the bar weight 5 extends long toward the bottom in the radial directional center in the vessel main body 1, when a residual quantity of the liquid cosmetics K in the main body 1 decreases, the liquid cosmetics K are guided along an outside surface of the bar weight 5, and can be smoothly flowed in the cylindrical passage A from the through hole 41 of the plug 4.

Abstract: PURPOSE:To raise pressure within an additional tank in a short time so as to reduce loads applied to an automatic pressure regulator by selecting either first or second pipeline using a control means which is operated in response to a signal from means for detecting pressure within the additional tank, the pipelines supplying air directly from air supply means or via the automatic pressure regulator to the additional tank. CONSTITUTION:To levitate a frame 1, a sequence circuit 7 receives a start signal for turning on a levitation starting button and then a contact-equipped pressure gauge 5 detects the pressure of an additional tank 2 and when the pressure of the additional tank 2 is low a solenoid valve 6a is opened so that air is supplied directly from an air supply means 8 to the additional tank 2. When the pressure is high the solenoid valve 6a is closed and a solenoid valve 6b is opened at the same time and air is supplied from an automatic pressure regulator 7 to the additional tank 2. At that point the frame 1 is levitated, and if the height of the frame 1 is sufficient the solenoid valve 6b is closed to stop air supply. To lower the frame 1, a lowering starting button is turned on and the solenoid valve 6c is either opened or closed according to whether the pressure of the additional tank 2 is high or low.

Title: Semiconductor pressure sensor
Inventor: KOSAKA HIDENORI
IPC: G01P15/12
Filed: 1989-04-14
Abstract: PURPOSE:To accurately measure a pressure without an influence of the change of temperature by arranging a heater in the vicinity of each pressure-sensitive element constituting a bridge circuit and detecting the ambient temperature of the pressure-sensitive element and controlling the current flowing to the heater to keep the temperature of the pressure-sensitive element constant. CONSTITUTION:When the ambient temperature falls, the resistance value of a temperature detecting diode 2 rises and a comparator input voltage gets lower than a reference voltage, and therefore, a signal in the high level is outputted from a comparator 3 and heaters H1 to H4 are operated to uniformly heat piezo elements P1 to P4. Thus, erroneous measurement of the pressure due to the variance of temperature characteristics of piezo resistance elements P1 to P4 is prevented. Meanwhile, when the ambient temperature rises, the resistance value of the temperature detecting diode 2 falls and the comparator input voltage gets higher than the reference voltage, and therefore, the output signal from the comparator 3 goes to the low level, and heaters H1 to H4 are not operated.

Title: Motor revolution control device
Inventor: OOTSUKA TOORU
IPC: H02P7/00
Filed: 1979-07-24
Abstract: PURPOSE:To increase the braking force applied to a motor by switching a polarity of a voltage applied to a magnetism sensitive element for determining the revolution direction of the motor when the output of a servo error detecting operational amplifier reaches a predetermined level. CONSTITUTION:When the revolution n2 of a motor 18 per unit time is less than a predetermined value, transistors 9, 10 are conducted to flow a bias current through a magnetism sensitive element 15 in a direction A. At this time the transistor 17 is controlled by the output of the operational amplifier 6. When the revolution n2 is raised over a predetermined value, the transistors 9, 10 are shut off, and the transistor 13 is conducted to flow a bias current in a direction B through the element 15 to reversely drive the motor 18. Since the transistor 19 so operates as to again raise the base potential of the transistor 17, the drive current supplied from the power supply terminal V2 operates to brake the motor 18.
