Title: Fixing device and both-face image forming device
Inventor: TANIGAWA KOICHI
IPC: G03G15/20
Filed: 1991-03-01
Abstract: PURPOSE:To prevent generation of winkles on a supporting material even if a bias having the same polarity as that of toner is applied to a fixing rotary body and a both-face image is formed by increasing a circumference from the central part of a pressuring rotary toward an end part side. CONSTITUTION:A pressuring roller 32 is constituted with a core metal 32A and an elastic body 32 composed of a silicone rubber, and has hardness lower than that of a fixing roller 31. In the roller 32, the outer diameter of an end part D2 is larger than that of a central part D1. Therefore, even if the surface images of flat black and a half-tone are printed by using a thin paper, the winkles do not generate. On the other hand, the roller 32 is elastic roller having low hardness, and elastically deformed on nip part, so that it is desirable that the reversed crown quality of the roller 32 is more than that of the roller 31.

Title: Press work turning-over device
Inventor: OOMORI OSAMU
IPC: B21D43/14
Filed: 1979-03-29
Abstract: PURPOSE:To obviate changing the position of the work before and after its turning- over, make the turning-over, one operation and reduce the time required for the turning-over,by providing the means of adsorbing and holding the work and turning it over at the center of the work perpendicular to the feed direction. CONSTITUTION:When the work 1 is received in a work receiving member 7, a sucker 21 touches the plane of the work 1 and holds the work 1. A rotating actuator 9 for receiving member actuates and a work receiving member 7 rotates, moving from the receiving position to the non-receiving position. Next, when an air cylinder for driving turning-over actuates, a turning-over shaft 15 rotates 180 deg., causing the work 1 to turn over. Thence, the rotating actuator 9 for receiving member resets and the work receiving member 7 returns to the receiving position. It receives the work 1 when the sucker 21 releases suction. In this state, the suction arm of the pressed work take-out feeder sucks the work 1 and carries to the press of the next process.

Title: Image communication equipment
Inventor: YAMASHINA MASAKI
IPC: H04N1/41
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in the transmission efficiency while keeping a prescribed image quality by controlling a frequency band for an object of re-transmission control in response to the transmission quality so as to permit an error in coded information at a high frequency band where an image error is unremarkable depending on the visual characteristic in the case of application of coding transmission to an original image. SOLUTION: A frequency conversion coding section 1-2 converts still image information into DCT coded data in the unit of conversion image blocks, quantizes a conversion coefficient and provides an output. A re-transmission control object frequency decision section 1-5 decides a conversion frequency area being an object for re-transmission control in compliance with rules to send a head part of a transmission image in error free. After the transmission of the image head, a band dependent Huffman coding section 1-3 applies Huffman coding to data while dividing frequencies into low and high frequencies based on the frequency decision obtained from the decision section 1-5. A transmission frame generating section 1-4 applies payload to the Huffman codes at high frequencies and a transmission control section 1-6 sends data with ARQ for low frequencies and without ARQ for high frequencies.

Filed: 1979-03-26
Abstract: PURPOSE:To make possible good printing by adding the emphasis charging process for charging the same charge particles as those in developing process between the developing process and transfer process. CONSTITUTION:I-VII show the entire process of dry type electrophotography. In the process I, negative charges 3 are given onto a photosensitive agent 1 by corona discharge. In the process II, light 4 is radiated to make a latent image. In the process III, the toner 5 having negative charge is deposited on the portions of the photosensitive agent which have lost the negative charge, whereby developing is done. The process VII is an emphasis charging process and deposit negative charge partices 7 further on the visible image. This increases the negative charges of the toner 5, increases the amount of the toner 5 sucked by the positive charges 6 in the transfer process IV, and improves the transfer effect. Even in the printing process such as the one which applies positive charges, the similar effect may be obtained by giving the positive charges in the emphasis charging process VII.
