Title: Sheet material feed device
Inventor: SAOTOME SUMITOSHI
IPC: B65H3/52
Filed: 1986-06-13
Abstract: PURPOSE:To make it possible to stably and surely feed sheet materials one by one, by forming a saw tooth-like irregularity section in the outer surface of a sheet-material separating pad attached to the top section of a sheet- separating mechanism. CONSTITUTION:A sheet-material separating mechanism 2 is pressed against a feed roller 1 under force by a spring. When the feed roller 1 rotates clockwise, the topmost sheet-material 7a is drawn in the feed direction to be fed into between the roller 1 and a pad 3a. At this time, the sheet material 7b right below the sheet material 7a is dragged by the latter and is therefore fed into between the roller 1 and the pad 3a. However, the leading end of the sheet material 7b abuts against an irregularity section 31 in the pad 3a so that it is inhibited from advancing. Thereafter, even though the rotation of the roller 1 is continued to feed out the sheet-material 7a, the advance of the overlappingly fed sheet material 7b is inhibited under hindrance of the irregularity section 31 and the resilient returning action thereof, and is therefore completely separated from the sheet-material 7a.

Title: Production of liquid crystal display element
Inventor: SHIBUYA MASAMICHI
IPC: G02F1/13
Filed: 1978-11-10
Abstract: PURPOSE: To make easy the formation of the sealing parts for liquid crystal by forming the sealing parts inner by the specified distance from the cutting positions for parting and forming these beyond the cutting positions at the liquid crystal sealing port side.  
     CONSTITUTION: Upper and lower electrode patterns not illustrated are formed on glass substrates 1 and orientation treatment for liquid crystal is applied, after which sealing material 3 is coated and formed. In this case, the sealing material 3 is coated and formed in such a way that only the liquid crystal sealing part 4a portions go beyond the cutting lines 9 for cutting and parting of the glass substrates 1. The other peripheral sides are coated and formed within 0.05W0.5mm inner than the cutting lines 9. Next, the substrates 1 are combined and are fined to set and bond the sealing material 3, thence te assembly is cut and parted from the cutting lines 9, whereby the individual liquid crystal cells are obtained. Thence, the parted liquid crystal cells are refired to fusion bond the frit on the cutting lines again. With this method the formation of the liquid crystal sealing parts 4a may be accomplished simultaneously with the coating of the sealing material 3 and therefore it is extremely easy.

Title: Multiplex communication device
Inventor: KIHARA YASUHIDE
IPC: H04L1/18
Filed: 1983-07-28
Abstract: PURPOSE:To send out new data and to improve transmission efficiency by resending only data of a terminal equipment which has no error checking function when an error in the transmission of multiplex data occurs. CONSTITUTION:When a multiplex signal M1 is received by a receiving station 2, circulation redundancy is checked on the basis of data a1-d1 and an error check code. The receiving station 2 checks the multiplex signal M1 from a transmission and reception part 15 by a checking part 16 and generates error signals E1 and E2 when an error is detected. The data a1-d1 received by the transmission and reception part 15 are distributed by a distribution part 17 to receiving registers 18-21, where they are set. A control part having received the error signal E1 generates a shift pulse S2. Consequently, the data a1 in the register 18 is shifted to a distribution register 23 and then sent out to a terminal equipment A' having an error checking function. A request-to-resend transmission part 27 having received the error signal E2 sends out a request-to-resend signal Q. A transmitting station 1 once receiving the signal Q resends the data b1-d1 and transmits a signal M2 containing new data a2.

Abstract: PROBLEM TO BE SOLVED: To make the output image density at the time of copying or the like have almost the same density in any cases by detecting whether read is to be performed from an automatic original feeding device or the read is to be performed from an original platen and performing luminance density conversion by using a different table in the plural kinds of luminance density conversion tables for determining the correspondence of a luminance value and a density value corresponding to the detected result. SOLUTION: The image sensor 301 of this reader divides the tip to the end of an original into many line lines and reads them and a luminance correction part 302 A/D-converts the output voltage and stores the luminance value for one white reference line in an internal memory. A luminance density conversion part 303 refers to the luminance density conversion table (RAM) 304 storing the correspondence relation of the luminance value and the density value and converts the obtained luminance value to the corresponding density value. In the case of performing the read from the automatic original feeding device of larger luminance compared to the original platen, the luminance density conversion table for which an output density value is larger to the luminance value is written from a ROM 305 to the RAM 304.
