Title: Method of forming fluorescent film
Inventor: SHIYOUDA MUTSUO
IPC: H01J9/227
Filed: 1978-08-18
Abstract: PURPOSE: To obtain pattern of narrow stripe width with high resolution by coating photosensitive fluorescent suspension added with organic dye having absorptivity in near ultraviolet rays on a fluorescent face, exposing it via a photomask to develop it, and then removing organic material therefrom.  
     CONSTITUTION: Fluorescent material is diffused in aqueous solution containing polyvinyl alcohol (PVA) or the like and bichromate. Then, suspension added with organic dye having absorptivity in near ultraviolet rays is coated on a fluorescent face. The fluorescent face thus coated is exposed via a photomask of predetermined pattern, and developed to then remove organic material contained in the film. For example, fluorescent material is diffused in mixture aqueous solution of PVA and (NH 4 ) 2 Cr 2 O 7 , and suspension added with aqueous blue dye such as triphenyl meth?ane or the like is coated on an aluminum deposited face of a face panel 1 by an ordinal flow coating process to form a fluorescent face as above. Thus, it can absorb light of high wavelength band of the sensitivity of sensitizer is absorbed by dye at exposing time to reduce the diffusion to thereby obtain pattern of narrow stripe width D with high resolution.

Title: Logical circuit
Inventor: ENOMOTO HIROSHI
IPC: H03K19/088
Filed: 1981-06-29
Abstract: PURPOSE:To decrease the power applying time for current flowing to an output transistor (TR) at switching, through the provision of a control circuit between  an on/off control input of an output TR and an output of a phase split TR. CONSTITUTION:A diode D2 as a control circuit element is connected from an on/off control section 3 of an output section TR2 consisting of transistors (TRs)  TRT5 and T6 to one output of a phase splitter TRT1. When a signal from an  input section 1 turns on the TRT1, the TRT5 turns off via the diode 2 and the  TRT6 directly turns on. The time when the TRT5 is turned from on-state to off- state can be decreased through the insertion of the diode D2. Thus, the time  when both the TRTs 5 and 6 are turned on is reduced and the power application time can also be reduced. The similar effect can be obtained by using a  capacitor as a control circuit in place of the diode.

Title: Method for coarsening optical fiber
Inventor: TAKEDA JUICHI
IPC: F21V8/00
Filed: 1988-04-26
Abstract: PURPOSE:To uniformly emit light by press-traveling an optical fiber thread or an optical fiber sheet-like material between a pair of a roller and a roller with fine projections on its surface. CONSTITUTION:The title method for coarsening optical fiber is to give fine projections to rollers 2 and 4, to pressurize and travel optical fiber between a pair of rollers 2 and 3 and a pair of rollers 4 and 5, thereby to give cracks and to leak light propagating in the optical fiber from the cracks. The number and size of cracks given to the optical fiber surface depend on the type of projections on the roller surface. If a sand paper no. 40, a coarse one, is used, the number of cracks on the surface is less and large cracks are given. Coarseness is compared in terms of light emitting brightness. If the roller with projections given by a sand paper no. 1000 coarsens optical fiber to form a light leaking part, longer material can emit light uniformly.

Title: Magnetic head
Inventor: KIKUCHI NORIO
IPC: G11B5/147
Filed: 1983-06-09
Abstract: PURPOSE:To raise a recording and reproducing efficiency, and to reduce a bias current and its adjusting range by forming at least one layer of resin layers of a magnetic core formed by laminating a magnetic thin plate and a resin layer, from a resin whose softening point temperature is high, and forming others from a resin whose softening point temperature is low. CONSTITUTION:In a core support assembly half body 5', each thin plate 2 which has removed a core thin plate 2' is laminated through a resin layer 3 whose softening point temperature is low, but the thin plate 2' is stuck to the core thin plate 2 of the inside through a thick resin layer 6 consisting of a resin whose softening point temperature is high. According to said constitution, since a thickness of the resin layer 6 is large, the core thin plate 2' is insulated completely from the adjacent core thin plate 2. Accordingly, in case a magnetic flux flows as indicated with a narrow M to a core half body 1' at the time of recording and reproducing, an eddy current will flow as indicated with an arrow C', but it is cut off by the resin layer 6. Therefore, an apparent magnetic permeability of a magnetic core does not drop, and a recording and reproducing efficiency o a magnetic head does not drop either.
