Title: Electrophotographic recording device
Inventor: KOIKE HISASHI
IPC: G03G15/08
Filed: 1989-06-05
Abstract: PURPOSE:To release an abutting position of a photosensitive body drum and a developing unit facilitating maintenance operation and at the same time to improve safety by interrupting a light path of a writing in laser beam by separating the developing unit from a developing position when a lid body of a paper feeding device etc. is in a released condition. CONSTITUTION:The cut sheet feeding device 6 is provided in an upper part of a housing body 1 by parallel linking mechanisms 7a and 7b, and is movable to two positions of a paper feeding position and an evading position. When the cut sheet feeding device 6 is made to be in the evading position from the paper feeding position, an L shaped part formed in periphery of a supporting point on the main body side of the parallel link 7b is brought into contact to a cam 72, is rotated in a clock wise direction around the supporting point 71 of the developing unit 30, and the abutting of the photosensitive body drum 24 and a developing sleeve 35 is released. Therefore, processing of paper jamming becomes facilitated and in the evading position, since the beam path 70 of the beam writing in unit 40 is interrupted, the beam can be prevented from leaking outside and safety can be improved.

Title: Laminated film chip capacitor
Inventor: WATANABE HISAYOSHI
IPC: H01G4/30
Filed: 1987-06-08
Abstract: PURPOSE:To obtain a small-sized and highly heat-resistant laminated film chip capacitor by a method wherein sheets containing a thermoset material are pasted on tow faces as cut faces of a capacitor device and the sheets are heated and hardened as external covers. CONSTITUTION:Evaporated electrodes 2, 3 are installed on both faces of a dielectric film 1; coated dielectrics 4, 5 are formed on them; then, a film A whose both faces are evaporated and coated is formed. Metalikon layers 6, 7 are formed on several sheets of laminated films A. Thermoset sheets of nonwoven cloths whose thickness is finished to be 0.2 mm, which are composed of polyester fibers and which are impregnated in advance with an epoxy resin are pasted on two faces as cut faces; after that, the sheets are heated and hardened; external covers 8, 9 are thus formed. Then, the nonwoven fabric functions in such a way that they are not moved due to the surface tension and a change in a viscosity of the epoxy resin and that they keep a thickness of the external covers constant. By this setup, a small-sized and highly heat- resistant laminated film chip capacitor is obtained.

Title: Production of stamper for lining
Inventor: HIRATA ICHIRO
IPC: C25D1/00
Filed: 1994-06-24
Abstract: PURPOSE:To rapidly and easily execute a lining operation by previously masking the part to be subjected to inside and outside diameter working in an electroforming stage at the time of successively coating a pattern-formed glass master disk with a conductive film and sputtered film. CONSTITUTION:The glass master disk 1 with patterns exposed and developed is coated with the conductive film 2 and is bolted via a holder 3A to an electroforming jig 3. The glass master disk is then coated with the sputtered film (electroforming film) 4, by which a stamper 11 for lining is formed. At this time, the part of the axial center 5A part of a mushroom-shaped inside- diameter mask 5 is previously inserted into a through hole 1A preformed in the central part of the master disk 1 and, therefore, the stamper 11 (conductive film 2 and the sputtered film 4) to be produced is only the conductive film 2 in the part masked with the inside-diameter mask and the outside-diameter mask (the inside-diameter part of the holder 3A). Easy inside diameter working and outside diameter working with scissors, etc., are thus possible. As a result, the stamper 11 is worked in the short period of time without damaging the stamper 11.

On the basis of the run count value read by the head 7, the contents of a tape run counter 4 are corrected automatically. Therefore, the accurate position of the tape is indicated on the run counter all the time and a data recording and reproducing device is controlled excellently.

Title: State signal transmission system for line switching loop network
Inventor: HAYAMA HIROYUKI
IPC: H04L12/40
Filed: 1987-06-10
Abstract: PURPOSE:To transmit a state signal of a general interface bus speedily by writing information on the change of the state signal in a corresponding bit of a transmission frame when detecting the change. CONSTITUTION:When general interface buses (GP-IBa, GP-IBb, and GP-IBc) are all in a state wherein an ATN (attention) signal is 'High' and an ATN bit in a sent frame 31 is '1', a node station 12a detects the change of the ATN signal of the GP-IBa to 'Low' if the signal changes, and writes 0 in the ATN bit in the sent frame 31. Other node stations 12b and 12c, on the other hand, detect the change of the ATN bit from '1' to '0' and send ATN signals 'Low' to the GP-IBb and GP-IBc. Consequently, the change of the state signal among GP-IBs divided by the line switching loop network is transmitted to other GP-IBs while the sent frame makes a round of the loop transmission line.

Filed: 1978-11-22
Abstract: PURPOSE: To prevent the decrease in the resistance between bars due to the cutting of the contour of a rotor, by providing perforated holes which extend in the axial direction between the enclosed slots of the rotor and the peripheral surface of a rotor core.  
     CONSTITUTION: A plurality of slots 2 are provided at a prescribed spacing so that the slots extend in the axial direction of a rotor core 1. Perforated holes 6 are provided between the slots 2 and the peripheral surface 4 of the core 1 so that the perforated holes extend in the axial direction of the core 1 and are located in positions corresponding to those of the slots. A conductor 3 such as aluminium is provided in each slot 2 by die-casting. The core is treated with heat. A gap 8 is formed between the conductor 3 and the slot 2 by the heat treatment so that the resistance between bars increases. When the peripheral surface of the core 1 is cut after the heat treatment, the stress due to the cutting resistance is absorbed by the perforated holes 6 and recesses are caused on the peripheral surface 4 but the slots 2 are not deformed. Therefore, the gap 8 due to the heat treatment can be maintained.

Title: Digital recording and reproducing device
Inventor: NISHIMURA KEIZO
IPC: G11B20/18
Filed: 1988-06-13
Abstract: PURPOSE:To easily and surely attain the propriety check of a recording medium and a recording and reproducing function with small size and light weight by providing a reproducing means reproducing a specific code block of a digital signal, a quality evaluation means evaluating the quality of the specific code block and a display means displaying the evaluation result. CONSTITUTION:A digital video signal reproduced from the final track on a magnetic tape 3 by a magnetic head 2 is subjected to code information at a reproducing circuit 4 and fed to a quality evaluation means 5. The quality evaluation means 5 has a code error detection circuit which compares the discriminating value of the occurrence state of code error with a preset prescribed value. If there is dirt on the magnetic head 2 or choking exists thereupon, since the S/N of a reproducing signal is deteriorated, a code error detection circuit of the quality evaluation means 5 detects much code error than the setting value and supplies the result to a display means 6. Thus, the recording and reproducing head for an information signal is used to check the recording and reproducing function and the small sized, light weight device is realized with low power consumption.
