Title: Recorder
Inventor: AMAYA MIKIO
IPC: G03G15/00
Filed: 1980-05-16
Abstract: PURPOSE:To attach toner particles in response to the strength of charges induced inside a recording body by an electrode by using a latent image forming film consisting of a dielectric having a high insulating property and the toner particles with high resistance, which have charges previously. CONSTITUTION:This invention relates to a device which uses a multistylus electrode and records an intermediate picture corresponding to applied voltage on plain paper. When a recording body 4 consisting of a dielectric having a high insulating property is contacted with a recording electrode 1 and negative voltage 5 is applied to an electrode needle 2 in response to picture signals, internal charges are induced to the recording body, and negative charges appear on the surface. Here, when a magnet 7 is fixed into a rotating sleeve 6 and toners 9 charged to positive charges are approached by means of carriers 8, the toners attach on the recording body by electrostatic force. When voids are regarded as extremely narrow, the quantity of charges Q stored in the recording body is CdV+Q0Cd/Ct, and adhering toners increase in proportion to voltage V applied to the recording electrode.

Title: Endless film for thermal transfer recording
Inventor: NOSE ISAMU
IPC: B41M5/392
Filed: 1984-04-03
Abstract: PURPOSE:To reduce the load in the switching work in an operator and to enble the security of good recording quality, by reinforcing and coating an endless film. CONSTITUTION:Heat-sensitive ink 9 supplied onto an endless film formed of polyimide having heat resistance forms an ink layer 11 and naturally cooled and solidified. When the solidified ink layer 11 reaches a heating means 13, a heat generation element selectively heats the ink layer 11 and the locally melted heat-sensitive ink 9 is transferred to recording paper 9 and the operation is repeated to record a charactor or a figure. In this case, an ink layer 5 comprising ink same kind as the ink 9 is preliminarily formed to the same film surface as one to which an ink layer is formed at the time of recording. It is unnecessary to make the thickness of said ink layer 15 same to that at the time of recording and said thickness may be several 10mum or less. Because an endless film is reinforced and coated by preliminarily forming the ink layer as mentioned above, there is almost no deformation of a film nor generation of static electricity and there is no surface contamination even if the film is directly touched with a hand and the load of an operator in the replacement of the film is reduced to a large extent.

Abstract: PURPOSE:To enable realization of a switching operation in a magnetic field in one direction by setting a resistance value of each magnetoresistance element so that the bridge of a magnetic detection circuit is not balanced and an offset voltage is outputted in a state wherein a magnetic field to be detected is absent.

By making a film in the part of a magnetoresistance element have a structure of lamination of a thin film 42 of a ferromagnetic substance, a Ti film 43 and an amorphous film 44 of CoZrMo, besides, an operation having no hysteresist characteristic is realized and the precision in detection is improved.

Next, for the purpose of controlling the roll speed of the stand 5, above stated thickness deviation signal is sent to the time processing chircuit 12, and the time required by the rolled material to travel from the stand 1 to the stand 5 is estimated from the outputs of the tachometer generators 17, 18, and then, the time constant is corrected correspondingly to the time lag. By this correction signal, the control unit 16 is controlled to obtain the final aim thickness.

Title: Abnormality detecting circuit for magnetic head
Inventor: YOSHINAGA MAKI
IPC: G11B5/455
Filed: 1986-03-26
Abstract: PURPOSE:To execute the highly accurate detection of shorting regardless of the position of a shorting place in a magnetic head by removing a high frequency component with a low pass filter even when an inductance component exists more or less at the time of shorting the head and a head terminal voltage causes ringing. CONSTITUTION:By load resistances R1 and R2 and capacitors C1 and C2 in a differential amplifier AMP, a filter having a time constant in proportion to a product is constituted. Consequently, when resistance values R1 and R2 and capacity values C1 and C2 are determined so that the time constant of the load resistances R1 (R2) and the capacitors C1 (C2) can enter between a period TD of a writing data signal and an average period Tp (TD and Tp are different by one digit or above) of the ringing of head terminal voltage e1 and e2 at the time of shorting, a high frequency component (ringing) is removed from the head terminal voltages e1 and e2. For such a reason, even when the shorting of a head occurs at places Y and Z and an inductance component remains, the abnormality of the head can be detected at the approximately same margin as the shorting at a code X.
