Title: Cleaning device
Inventor: MISAIJI TAKASHI
IPC: G03G21/10
Filed: 1982-03-11
Abstract: PURPOSE:To display excellent sweeping performance even if foreign materials is entered into between an electrostatic latent image carrier and a supporting plate in a cleaning device having a blade by using an elastic member for a surface layer which contacts the electrostatic latent image carrier. CONSTITUTION:A belt 20 as the filmlike electrostatic latent image carrier runs as shown by an arrow and the blade 13 is in press contact with the belt 20. The supporting plate is made of a rigid body like metal and the elastic member 22 like polyurethane rubber is adhered to the surface of the supporting plate 21. For example, foreign materials 23 and 23a are intruded between the belt 20 and elastic member 22 and when the edge 13a of the blade 13 passes over the foreign material 23, the foreign material 23 is embedded in the elastic the belt 20. Therefore, the edge 13a scrapes out toner completely without spacing the surface of the belt 20. Consequently, even if foreign materials intrude between the latent image carrier and supporting plate, excellent sweeping performance is obtained.

Title: Facsimile receiver
Inventor: SUZUKI MASAMI
IPC: H04N1/23
Filed: 1981-03-16
Abstract: PURPOSE:To prevent control signals and noises from being recorded by checking whether a received signal is a picture signal or not, in every line and applying only the signal recognized as a picture one to a recording head. CONSTITUTION:Signals demodulated by a demodulator 1 are written in memory devices 2, 3 interchangeably in every n lines. A picture signal carrier detector 5 detects whether signals inputted to the demodulator 1 include picture signal carrier or not and the discriminated results of signals written in the memory 2 and that in the memory 3 are stored in registers 6 and 7, respectively. These picture signals and discriminated results are read out interchangeably from the memory 2 through the register 6 and the memory 3 through the register 7 and stored in a shift register 11 through multiplexers 8, 9 and an AND gate 10. When every n bits are stored, these picture signals are outputted from the register 11 and applied to a recording head. Thus, no useless signals such as control signals and noises are recorded.

Abstract: PROBLEM TO BE SOLVED: To correctly align a spiral steel tube by forming a projecting bar of the prescribed width to be brought into contact with the steel tube on a circumferential surface of a turning roll for detecting the tube circumferential length to realize the stepped structure. SOLUTION: A turning roll is provided below an aligning and marking device for steel tube pile sheet, and comprises a turning roll for drive and a turning roll 1b for detecting the tube circumferential length, and a rotation measuring instrument 1c is connected to the turning roll 1b. A projecting bar 1d to be brought into contact with the steel tube is formed on a circumferential surface of the turning roll 1b for detecting the tube circumferential length to form the turning roll 1b for detecting the tube circumferential length. When the width of the projecting bar 1d is below 10mm, the bearing pressure of the projecting bar becomes too high, and the projecting bar is squeezed, and the width is set to be 10-50mm because the width of 50mm is the maximum limit to secure the accuary of the allowable bend ±2.5mm.  In manufacturing the steel tube pile sheet, the steel tube can be correctly aligned in the direction of 180 deg. before a joint is welded to the steel tube.
