Title: Soft touching water-sealed unit
Inventor: NITSUTA MISAO
IPC: E02B7/54
Filed: 1979-02-03
Abstract: PURPOSE: To improve the water sealing by closely pressing a rubber film against the sliding side opposite thereto by a difference between the external and internal water levels with a hydrostatic pressure introduced into a rubber film chamber composing the sealing section in a water-sealed unit of the water gate.  
     CONSTITUTION: A rubber film 11 is spread properly tensioned between two brackets 10 and 10 provided in a loop on the circumference of the base 8 made up of a cylindrical ring to form a rubber film chamber 12 surrounded by the rubber film 11. A hydrostatic pressure introducing hole 13 communicating to the rubber film chamber 12 is provided on the upper bracket 10. The base 8 is securely fitted into an inner cylinder 14 of a cylinder gate through an 0 ring 15 and the water- sealed unit is mounted between the inner and outer cylinders of the cylinder gate. In this manner, the hydrostatic pressure P 1  outside the cylinder gate is applied to the rubber film chamber 12 through the hydrostatic pressure introducing hole 13 thereby ensuring an even water sealing compression with the outer cylinder 22 of the water sealed unit.

Abstract: PURPOSE:To make it possible to feed paper by manually rotating a platen without damaging a printing head, by controlling a printing head so as to move the same in a direction away from the platen by a signal detecting that the voltage of a power source reached predetermined voltage or less. CONSTITUTION:When a paper source is cut off during usual printing operation, that is, while a printing head 3 presses paper 4 to a platen 1, the cutting-off of the power source is detected on the basis of the voltage group of a DC power source by a voltage variation detection circuit 7 and the detection signal thereof is sent to a head moving control circuit 6. The head moving control circuit 6 drives a stepping motor 5 on the basis of said detection signal before the DC power source is perfectly cut off to move the printing head 3 to a home position.

Title: Method of judging propriety of use for voltage non- linear resistor
Inventor: ISHIZUKA MASARU
IPC: G01R19/165
Filed: 1981-01-28
Abstract: PURPOSE:To permit to simply judge propriety of use for a voltage non-linear resistor by a method wherein AC voltage applied to the voltage non-linear resistor is gradually increased so as to determine the voltage when a current passing through the voltage non-lenear resistor exceeds a predetermined value. CONSTITUTION:With an operating current I of a current detector 12 being preset, voltage is gradually increased using a voltage regulator 8, so that a current passing through a voltage non-linear resistor 10 is increased and the current detector 12 starts to operate. The circuit voltage at this time is read out by an AC voltmeter 9. Now assuming that the read-out voltage is V2, a difference v2 between V2 and voltage V3 of a limit value represents surplus voltage, which is checked at the time of maintenance and inspection. A period of time from the voltage V2 to the limit voltage V3 varies depending on service life characteristics of each voltage non-linear resistor 10 and a degree of stress applied. When the result shows that the resistor 10 has reached the limit of its service life, it will be replaced on new one

Abstract: PROBLEM TO BE SOLVED: To prevent wrong photographing of a white board in which character information is unclear due to the regular reflection of an illumination light. SOLUTION: The photographed image of a character information written on a white board and fetched by a CCD 20 is inputted in a histogram production part 323c via an A/D converter 321.

A regular reflection detection part 323g decides whether any one of small image includes an image of illumination light reflected regularly on the white board, based on the shape of every histogram. If the regular reflection light is detected in a small image, a warning is produced via a buzzer, an LED display, etc.  The regular reflected light, included in the photographed image is detected for every small image, and the regular reflection warning is produced according to this detection result Thus, it is possible to prevent erroneous photographing of an image having ambiguous character information, due to the regular reflection light.
