Inventor: FUKUDA SEIKICHI
IPC: G01F23/28
Filed: 1989-10-31
Abstract: PURPOSE:To surely detect an interface even when few specific gravity or impedance between upper and lower layers exists by receiving modulated light projected from the inside of a guide pipe on one side to that of a guide pipe on the other side, and detecting the interface by observing the output level of a light receiving means with a modulation light reception circuit. CONSTITUTION:A pair of guide pipes 22, 24 are provided with translucent property, and are arranged keeping a prescribed gap. Also, a modulation light driving circuit drives a light emitting means by outputting a modulation signal. The light receiving means receives the modulated light projected from the inside of the pipe 22 on one side to the pipe 24 on the other side via the pipes 22, 24 and an object to be inspected. The modulation light reception circuit detects the interface 8 with the interface detector 10 by observing the output level of the light receiving means. Therefore, since there is no influence on the transmittancy of the upper layer 4 and the lower layer 6 even when the specific gravity or the impedance of the upper layer 4 and the lower layer 6 is changed, the interface 8 can be surely detected. Similarly, when small difference in the specific gravity or impedance between the upper layer 4 and the lower layer 6 exists, the interface 8 can be detected.

Looseness of the pin joining part is eliminated since this wire 13 presses a connector 3 to the six rib 12 side. High rigidity can be easily obtained by forming a loosenessless structure by tensioning the wire 13 between the respective hexagonal pyramid apexes.

Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent any skew in a small-sized sheet from occurring as well as to make improvements in handleability in time of its attachment to an image former, and besides, letting it have universality in terms of usage. SOLUTION: A first sheet width regulating plate 29 and a second sheet width regulating plate 31 being situated in space between a paper feeding part 30 and a manual paper feed roller 23 both are installed in a tray body 28 in a state of being connected by a connecting member 32. Therefore, even in a state that a sheet is reached to the inner part of a manual feed port 25, a position of a side edge of the sheet is regulated by the second sheet width regulating plate 31 and thereby any skew is preventable from occurring. In addition, both these sheet width regulating plates 29 and 31 installed in this commonable tray body 28 are surely connected to each other without requiring the release of the connected state, and further, such a job as connecting these plates 29 and 31 each time when this automatic paper feeder is attached to an image former body is thus omissible. Moreover, since this automatic paper feeder is usable independently, not to use in setting-up with another paper feed tray in combination, universality is impartable to it.

In the reuse, the hot water stop valve 4 is released and the hot water of lower temperature inside the main hot water supplying pipe 2 is supplied to the hot water storing thermal-insulation tank 5 through the under part of it.  As the hot water inside the hot water storing thermal insulation tank 5 is thermally insulated and the temperature drop of it is lower, it is pushed upward from lower part and sent through the destination hot water supplying pipe 3 opening at the upper part of it to a combination taps 6. Thus the hot water of lower temperature inside the main hot water supplying pipe 2 is mixed with the hot water inside the hot water storing thermal insulation tank 5 gradually and sent out.
