Title: Reversible thermal recording material
Inventor: KAWAGUCHI MAKOTO
IPC: B41M5/36
Filed: 1990-11-26
Abstract: PURPOSE:To form and erase an image uniformly even if foreign particle, dust, and the like adhere to the surface of a reversible thermal recording material by providing a protective layer or intermediate layer mainly composed of a resin having rubber elasticity. CONSTITUTION:A layer mainly composed of a resin having rubber elastisity is provided on a heat-sensitive layer as a protective layer or between a heat- sensitive layer and a protective layer as an intermediate layer. As the resin having rubber elasticity, butadiene rubber, urethane rubber, polysulfide rubber, butyl rubber, and the like are exemplified. The thickness of the protective layer is the order of 0.1-10mum. By using a resin having an elongation of 100% or more as the resin having rubber elasticity, the resin having rubber elasticity is shrunk to improve an adhesion of a reversible thermal recording material to a thermal head or the like when an image is formed/erased by the heat of the thermal head even if foreign particle, dust, and others adhere to the surface of the reversible thermal recording material. In this manner, the heat is uniformly transmitted to the reversible thermal recording material to ensure a uniform image forming and erasure.

Title: Fixing unit
Inventor: FUJIMOTO RYOICHI
IPC: G03G15/20
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the permanent deformation of a pressure roll by the rotation of roll by rotating/driving one roll with respect to another roll when a specified time lapses without rotating two rolls. CONSTITUTION:An elapsed time counting part 2 starts to count the time elapsed t0 from the completion of printing/copying when a signal from a fixing unit class detecting part 1 is active. When the printing/copying are executed after the counting is started and before a set time t1 is over or a time-up signal is detected from a comparing/deciding part 3, the time elapsed t0 is reset. When the relation between the time elapsed t0 counted by the elapsed time counting part 2 and the set time t1 is (t0>=t1), the time-up signal is outputted from the comparing/deciding part 3. A fixing unit driving control part 4 usually receives a normal time driving signal to rotate/drive the roll. Moreover, when the control part 4 receives the time-up signal as well, the control part 4 rotates/drives the roll to prevent the permanent deformation of the pressure roll.

Filed: 1987-12-21
Abstract: PURPOSE:To obtain the title magnetic sensor which eliminates the need for exciting winding by supplying a pulse or AC current in the length-wise direction of a conductive magnetic body and detecting an external magnetic field by detection winding provided around the magnetic body. CONSTITUTION:A monolithic wire or rod-shaped magnetic body 10 which has no magnetic strain is formed of a Co magnetic material. The pulse current or AC current is supplied from a power source 11 in the lengthwise direction of the magnetic body 10. The magnetic body 10 is wound with the detection winding 12. An internal magnetic field Hi is produced in the circumferential direction of the magnetic body 10 with the pulse current or AC current and an external magnetic field Ho is detected by the detection winding 12 as an electric signal with the Hi. A voltage Eo is developed at the output terminal 13 of the detection winding 12 with the voltage pulse Ei of the power source 11. The crest value H of the Eo when the pulse current rises and falls is larger and larger as the intensity of the external magnetic field Ho is larger and larger and the direction of the Ho is closer and closer to the direction of the magnetic body 10 on condition that the intensity of the external magnetic field Ho is smaller than a prescribed value. This constitution eliminates the need for exciting winding for the magnetic sensor and has high sensitivity.

Title: Manufacture of ceramic molded body
Inventor: NAKAI HIDEO
IPC: B29C39/02
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To obtain a faultless ceramic molded body by a method wherein a slurry is poured in a cavity having a predetermined shape and heated so as to bring the sum of the cure shrinkage of a thermosetting resin and the thermal expansion of the slurry near to a specified value. SOLUTION: A sample of a slurry is put in a rubber container and then immersed in an ethylene glycol so as to measure the buoyance at time with an electron balance in order to calculate the specific gravity of the slurry. Heating is carried out so as to bring the sum of the cure shrinkage of a thermosetting resin and the thermal expansion of the gelled slurry near to zero. Thus, the cure shrinkage of the thermosetting resin and the thermal expansion of the slurry are canceled each other, resulting in relaxing the internal stress in a ceramic molded body and obtaining a faultless ceramic molded body.
