Title: High-precision device for measuring distance
Inventor: FUJITA SHIYOUZOU
IPC: G01S13/36
Filed: 1982-03-01
Abstract: PURPOSE:To eliminating the influence of temperature fluctuation characteristics of a narrow-band filter and perform high-precision measurement, and to simplify device constitution, by calibrating the phase variation of the filter in a sufficiently short time. CONSTITUTION:A tone for distance measurement from a generation part 4 is inputted directly to a tone filter 5 through a switch 3 to take a measurement 6 of the phase difference between output tones of the generation part 4 and the filter 5. This measurement data is supplied to a storage part 8 through a switch 7. Through the continuance of this measuring operation, invariably new data is stored. Once this operation is started, actual distance data from a terminal 2 is supplied to the filter 5. Substraction 9 between data in the storage part 8 right before the operation and phase-shifted distance data is carried out and the phase data is coverted into real distance data at a section 10. Therefore, the phase variation of the filter 5 right before the operation is measured invariably and stored as a calibrated value.

Title: Thin-walled insulated wire
Inventor: HIRAI SHOICHIRO
IPC: C08L27/06
Filed: 1990-02-13
Abstract: PURPOSE:To obtain a thin-walled insulated wire of excellent abrasionproof property by providing on a conductor a thin layer of a composition that contains at least 1 part by weight of methacryl or styrene resin against 100 parts by weight of vinyl chloride resin. CONSTITUTION:Methacryl resin (polymethacryl acid methyl) and styrene resin are each singly blended with vinyl chloride resin or may be used together. The amount of the former resin is at least 1 part by weight against 100 parts by weight of the vinyl chloride resin. If the amount exceeds 60 parts by weight, the effect of enhancing productivity cannot be obtained. A monomer of more than 3 functional groups, e.g. a composition comprising 1 to 20 parts by weight of trimethylol propane trimethacrylate and the like mixed in 100 parts by weight of polyvinyl chloride resin is extruded on a conductor so that the conductor is covered therewith, and, after a thin layer is formed thereon, a layer of insulators consisting of bridged bodies is formed by application of radiation rays, so that the abrasionproof property of the conductor is further enhanced.

Title: Image forming device
Inventor: TAKAGI OSAMU
IPC: G03G15/05
Filed: 1992-02-19
Abstract: PURPOSE:To contrive stabilized output of image always by enabling imparting of vibration acceleration to only an aperture causing the toner flow not to be generated, by a method wherein an aperture electrode imparting the vibration acceleration only to the aperture causing the toner flow to be generated is provided. CONSTITUTION:When (-) direct current voltage which is applied to a control electrode 108 of an aperture which is desirous of generation of a toner flow is made into an electric signal by overlapping alternate voltage having frequency fr on the (-) direct current voltage, a piezoelectric element 14 coming into contact with the electrode 108 becomes elastic vertically and at the same time, an aperture forming part also on the inside of the electrode 108 is exited by its natural frequency. At this time, even if the charged toner particles are apt to stick to the vicinity of an aperature forming part 12 by force of a reflected image, since vibration acceleration by a vibration is generated on the aperture adhesion is impossible. On the one hand, when a fixed voltage is applied beforehand to a corresponding control electrode layer of the aperture, which does not cause the toner flow to be generated, the piezoelectric element does not become elastic and the vibration acceleration is not imparted bed to the aperture also. Therefore, the toner flow is modulated stably always by a signal source S and recorded on a substrate P.
