Title: Photosensitive and heat sensitive recording material
Inventor: NAKAMURA TATSUO
IPC: B41M5/00
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To ensure superior sensitivity, shelf stability and development latitude by successively disposing a 1st layer containing a water-insoluble and alkaline water-soluble polymer and a 2nd layer having a polarity changing material which changes from a lipophilic material into a hydrophilic material under heat on a substrate. SOLUTION: A 1st layer containing a water-insoluble and alkaline water-soluble polymer and a 2nd layer having a polarity changing material which changes from a lipophilic material into a hydrophilic material under heat are successively disposed on a substrate. Since the polarity changing material is used in the surface layer which generates large heat, the penetrating property of a developing solution is enhanced, the difference in dissolution rate between exposed and unexposed parts is increased and high sensitivity is ensured. The developing solution penetrates from the surface layer to the interface of the substrate even after preservation because of its high penetrating property and develops even the water-insoluble and alkaline water-soluble polymer highly associated near the interface and shelf stability is improved.

Title: Image forming device
Inventor: MIWA SHINJI
IPC: G03G15/02
Filed: 1987-08-28
Abstract: PURPOSE:To measure the characteristic of each type of electrostatic charger by means of an image forming device itself by detecting an electric current flowing from an image carrier according to the action of an electrostatically charging means by means of a detecting means and obtaining an electrical potential on the surface of the image carrier in response to the electric current by means of a control means. CONSTITUTION:With a control part set in a measuring mode, electrical charges are projected on the surface of a photosensitive body drum 11 by moving the required electrostatic charger and a leaking electric current is detected which is caused by projecting the electrical charges to a destaticizing body. The electrical potential, etc., on the surface of the photosensitive body drum 11 corresponding to the leaking electric current are displayed on the display part 17c of an operation panel 17. Therefore, when the electrical potential, etc., on the surface of the photosensitive body drum 11 are measured, it becomes unnecessary to replace the photosensitive body drum with a jig or to connect a different type of ammeter. Thus, the image forming device itself can perform measuring and a measuring work can be simplified.

Abstract: PURPOSE:To always grasp who and where in case each personnel in a building brings an IC card incorporating a radio transmitting and receiving function by arranging dispersedly the radio transmitting and receiving function of a weak radio wave on each floor F by a local station. CONSTITUTION:A data collecting command is outputted from a CS 11, transmitted to an LS 12 by a radio, and the LS 12 transmits an ID calling request to an IC card 13 in its own area.

Abstract: PURPOSE:To stop the operation of a correcting means at that time point even if a storage means stores an erroneous value due to noise, so that an error of a tracking error signal does not become larger by operating the correcting means only when a sector mark signal and a total reflection area instructing signal are detected alternately. CONSTITUTION:This circuit is provided with a first signal inspecting means 1 for inspecting a fact that a total reflection area instructing signal 20 and a sector mark signal 13 are detected alternately as a pair, and a second signal inspecting means 2 for checking a fact that the total reflection area instructing signal 20 or the sector mark signal 13 or a signal for showing a pair of both the signals is inputted at least once after an output of the signal detecting means 1 becomes active. In this case, when an output 16 of a second signal inspecting means 2 goes to active after the output 15 of a first signal inspecting means 1 goes to active, an offset correction of a tracking error signal is executed. In such a way, an offset can be eliminated exactly from the tracking error signal.
