Title: Electrophotographic printer
Inventor: NISHIKAWA TOMOYUKI
IPC: B65H23/188
Filed: 1990-04-13
Abstract: PURPOSE:To prevent the looseness of a consecutive sheet between a photosensitive body and a heat roll fixing device and to prevent skew caused by this looseness by setting the carrying speed of a consecutive recording sheet with the fixing device higher than the rotational peripheral speed of the photosensitive drum at a prescribed rate. CONSTITUTION:The photosensitive drum 1 and the heat roller 81 of the fixing device 8 are composed so as to be rotated and driven by the same driving source, and their rotations are completely synchronized with each other. At this time, the peripheral speeds of the photosensitive drum 1 and the heat roller 81 are set so that the peripheral speed of the photosensitive drum 1 with respect to the peripheral speed of the heat roller 81 is slightly delayed. Thus, the consecutive sheet 9 between the photosensitive drum 1 and the fixing device 8 has tension by the difference between both carrying speeds, so that the looseness of the consecutive sheet 9 is prevented and the occurrence of the skew is inhibited.

Title: Sewage purifying apparatus
Inventor: MIYAZAKI TOSHIHIRO
IPC: C02F3/06
Filed: 1978-08-11
Abstract: PURPOSE: To easily maintain a purifying apparatus with a flow rate regulator handling purified sewage by setting the regulator in a settling chamber and by continuously feeding a fixed vol. of sewage, into a disinfection chamber, subjected to sedimentation separation of solid matter, aeration and settling.  
     CONSTITUTION: Solid matter in inflow sewage 5 is settled in sedimentation separation chamber 3. The intermediate water is fed into aeration chamber 2 through opening 11 and purified. The purified water enters settling chamber 3 and is fed into disinfection chamber 4 with flow rate regulator 3. Since sewage 5 is stored or reduced in chambers 1, 2, 3, the vol. of sewage 5 differs from the vol. of water drained, and the water levels in the chambers change. However, regulator 6 constantly feeds the purified sewage in chamber 3 into chamber 4, and the vol. of water drained is also made constant, so the purification function of the apparatus is maintained at a high level.

Abstract: PURPOSE:To enable to form a wiring having a sufficiently smaller capacity by a method wherein the titled device is made into a structure, wherein the wiring comes into contact with insulators formed on the substrate in an electrically insulated state in addition to parts, whereto the wiring is electrically connected. CONSTITUTION:N<-> type diffusion layers 12 and oxide films 13 for element isolation are formed on a P type silicon substrate 11 having a (100) plane and a resistivity of 10OMEGA.cm, and furthermore, in the structure with a wiring 14 formed therein, the wiring 14 comes into contact electrically with the N<-> type diffusion layers 12, and at the same time, is coming into contact with the oxide film 13 by a pedestal in an electrically insulated state. By forming such the pedestal, the strength of the wiring 14 can be sufficiently held. That is, this way is aimed at reinforcing the strength by erecting the pedestal in the middle of the oxide films 13, because the wiring 14 is not sufficient in view of strength in a condition that the wiring 14 is coming into contact with only the N<+> type diffusion layers 12. Accordingly, a wiring having a capacity far smaller than the conventional one can be formed.

IPC: E21D9/06
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To secure water stop performance by using a segment having a segment outer peripheral side shape formed in parallel to the taper part as a segment used in the taper part. SOLUTION: For example, in a circular arc-shaped segment, the width directional outer peripheral side is formed in a taper shape in both side surfaces 11z, 11z to prevent a step difference between rings in the segment outside surface. Or a width directional cross section is formed as a parallelogram to prevent a step difference between the segment inside/outside surfaces. Therefore, since the segment outside surface is formed in a taper shape, a tail seal plate 13a of a tail seal 13 is set by following the segment outer periphery. Since clearance between the segment outer periphery and bedrock is almost constant, the tail seal 13 can be arranged without requiring to lengthen and increase bristles of a seal brush 13b. Therefore, water stop performance can be easily improved.
