Title: Paper feed mechanism used in electrophotographic printer
Inventor: NONAKA MANABU
IPC: B41J13/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To reliably prevent damage of a sheet of recording paper caused by its buckle and accurately position a sheet of recording paper at its resist position by a resist roller pair in an electrophotographic printer. SOLUTION: In order to regulate the pressure force FR applied on a sheet of recording paper P by a roller-pressure regulator means 22, with the pressure force FR being minimized, the recording paper P is fed by a feed roller pair 21 holding it therebetween and is fixed at a downstream position with respect to the feed roller pair 21 and then the feed force FP of the recording paper P is measured. In that state, although a pressure roller 21b idles with respect to the recording paper P, a gradual increase in the pressure force FR by the roller-pressure regulator means 22 correspondingly increases the measured value of the feed force FP.  When the measured value of the feed force FP reaches an arbitrary desired value in a range between 200gf to 300gf, the magnitude of the pressure force FR by the roller-pressure regulator means 22 is held constant to obtain an appropriate pressure force FR.

Title: Water supply system
Inventor: YAMAGUCHI HIROSHI
IPC: F04D15/00
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To stop a pump in a water shortage condition and to eliminate stoppage of the pump even when discharged water is released to atmosphere with a low-cost structure. SOLUTION: In this water supply system, water in a tank 3 is fed by an electric pump 2 to a discharge water valve 16. As the inside of a link 13 gets to a specified pressure, a pressure switch 18 is opened, and a pressure regulation valve 12 is actuated for relief. This excessive water pressure is detected by a pressure switch 19, and the pump 2 is stopped by a controller 9. As pressure in the line 13 falls, the pump 2 is operated by a detection signal. At this time, the pressure switches 18, 19 detect pressure of more than zero when flow exists because of existence of orifices 17, 21.  In a water shortage condition, therefore, both pressure switches 18, 19 detect pressure of zero, and the pump 2 is stopped by the controller 9, but when the line 13 is released to atmosphere by opening a lot of the discharge water valves 16, the switch 18 detects its flow pressure, thereby the pump 2 is not stopped.

Title: Pressure sensor
Inventor: WAKAMIYA MASAYUKI
IPC: G01L9/16
Filed: 1986-10-20
Abstract: PURPOSE:To eliminate sharp change in the sensor output in a low pressure area as caused by a deflection, by applying a pressure to an amorphous alloy across the thickness thereof to induce a compression stress without deflection of the alloy across the thickness. CONSTITUTION:As an oil pressure is applied to a hydraulic pressure introduction port 9, a pressure works on an amorphous magnetic alloy 2 through a non- magnetic lid section 4 to apply a compression stress to the entire surface of the amorphous magnetic alloy, yet the amorphous alloy itself maintains the most of the shape thereof without local deflection. The resulting internal stress reduces the magnetic permeability of the amorphous magnetic alloy by a stress magnetic effect. The changes in the permeability are detected with a coil 8 in the form of inductance to measure the oil pressure.
