Title: Fixed heat capacity valve
Inventor: SAKAI SHIGEO
IPC: F16K31/68
Filed: 1982-04-22
Abstract: PURPOSE:To allow a fixed quantity of fluid to flow out irrespective of the fluid pressure, and to adjust the flow quantity in proportion to the fluid temperature. CONSTITUTION:A fluid flowing in through a fluid inlet port 2 flows into an intermediate chamber 32 as the primary pressure fluid from a circular chamber 30 through an end chamber 33 and passage 34 to affect a movable bulkhead 8. Since the fluid in the end chamber 33 flows into an outlet side chamber 31 through the inside of a valve port 6 and the periphery of a heat sensitive expansion element 24, the pressure of the outlet side chamber 31 affects the movable bulkhead 8. Therefore, even if the pressure of the circular chamber 30 and outlet side chamber 31 is changed, the pressure difference between the front and rear of a flow quantity adjusting valve 21 is constant, thereby a fixed quantity of fluid flows out. In addition, when the temperature of the fluid around the heat sensitive expansion element 24 is elevated, the opening area of the adjusting valve body 21 is expanded.

Title: Side-unnecessary image erasing device of electrophotographic copying machine
Inventor: TAKATOU AKIHIRO
IPC: G03G15/04
Filed: 1984-04-03
Abstract: PURPOSE:To obtain the proper quantity of image erasure in any feed mode and to prevent the formation of black stripes at an end part by recognizing previously the proper quantity of image erasure in every feed mode and changing the quantities of image erasure according to a change in mode. CONSTITUTION:When a copy is taken by using a form of, for example, B4 size, an image outside an image area is all erased preferably. When the specified side of a drive controller 23 is B4, constant currents are supplied to light emitting diodes L1, L2, L60, and L61. At this time, when the feed mode of an original is a manual mode, the operation signal from an automatic original feeding mechanism 24 is turned off and a feed mode switching adjusting device 25 performs current control in manual feed mode to control the current flowing to a constant current source 22. When an original is sent by the automatic original feeding mechanism 24, the operation signal from the mechanism 24 is inputted to the feed mode switching adjusting device 25 to perform the current control in automatic feed mode, and its operating current is controlled so that the arrival range of irradiation light from the light emitting diodes L1, L2, L60, and L61 is expanded as compared with that in manual feed mode.

Title: Method and apparatus for detection of ripple on molten metal bath face
Inventor: EGUCHI NOBUYUKI
IPC: G01N21/47
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an adhesion irregularity inside a plating bath can be detected by a method wherein a liquid-metal bath face is irradiated with a spotlike laser beam, the detection time interval of reflected light on the bath face at an angle agreeing with a light-receiving angle is found and the height and the angle of ripples on the bath face are measured. SOLUTION: When a copper plate 3 is pulled up to the vertical direction from a plating bath 1 for a liquid metal to be measured, ripples 2' are generated on a bath face 2. In this situation, a laser light source 4 by which the bath face 2 is irradiated with a spotlike laser beam is installed in the vertical direction of the bath face 2, and a detector 5 which detects reflected light is installed in one place inside a face which is at right angles to the copper plate 3 and the bath face 2. Consequently, out of laser reflected light 12 whose angle is changed due to the periodic change of the bath face 2, only reflected light whose angle of reflection agrees with a set angle θ at the detector 3 is detected by the detector 5.  Then, the cycle of the ripples 2' is decided not by a value between adjacent detection signals but by a value between detection signals which appear so as to be delayed by a certain time, and the height of the ripples 2' is computed on the basis of the decided cycle. On the basis of the found height and the decided cycle of the ripples 2', an adhesion irregularity inside the plating bath can be detected.

Filed: 1985-04-01
Abstract: PURPOSE:To prevent an overvoltage and an overcurrent from occurring when a current collector passes a section by detecting the current collecting state of the collector, and gradually reducing a control current flow rate in response to the variation in the detected value. CONSTITUTION:A comparator 16 outputs a signal when the variation Ecf of a filter capacitor voltage Ecf comes to a reference value or higher. A main motor current reducing circuit 2 outputs a pulse to gradually reduce a main motor current IM to the gate of a chopper. When a time T4 is elapsed,a timer 21 is operated to open a gate circuit. When time T4+T5 is elapsed after the comparator 16 outputs a signal, a timer 22 is operated to restart a chopper. Thus, it can prevent an overvoltage and an overcurrent from occurring when a current collector passes a section.
