IPC: B41J2/015
Filed: 1988-12-20
Abstract: PURPOSE:To make recording density high by a method wherein an ink of high viscosity is partially heated by a thermal head provided in a slit section thereby to lower the viscosity thereof to control jetting of said ink. CONSTITUTION:An acoustic energy generated from piezoelectric elements 16, 17 each in the form of a flat plate provided at the liquid surface is concentrated into a slit section 13 by a reflecting part 10 having a parabolic surface and provided in the liquid to jet out the ink.

Abstract: PROBLEM TO BE SOLVED: To reduce processing load upon a controller and a terminal and to simplify their configurations by making an allocation communication part reallocate transmission right to the terminal when transmission from one terminal does not finish at a point when a specified period of time elapses. SOLUTION: A control device 10 gives a terminal 11k the transmission right of a transmission line 12 on the basis of a transmission request from the terminal 11k for a specified period. That is, a time slot (an upstream communication area) on an upstream line on the transmission line 12 is allocated to the terminal 11k. The control device 10 judges whether or not transmission of data from the terminal 11k is completed at a point when this specified period of time has elapsed. When data transmission is not completed, the time slot on the transmission line 12 is reallocated to the terminal 11k for the specified period. Thus, the configuration of the control device 10 and the terminal 11k are simplified and processing loads upon the control device 10 and the terminal 11k can be reduced.

IPC: B65G59/02
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To precisely check the number of loading steps of cases in simple and inexpensive constitution using rising motion of a pallet. SOLUTION: An upper end position of cases 6 is detected by a detector 2 by raising a pallet 7 on which the cases 6 of the same height are accumulated in steps by a lifter 1.

Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To encode a moving image at a variable rate and in real time and to obtain the encoding data of high picture quality in a short time by deciding the quantization width by the function arithmetic processing and based on the average quantization width as well as the number of codes produced per unit time in an image. SOLUTION: This moving image encoding device decides the quantization width by a code number controller 106. A code counter 301 of the controller 106 counts the number of codes produced in every screen, and an average quantization width computing element 302 calculates the average quantization width in every screen. A unit time information calculator 303 calculates the number S1 of produced codes converted into each unit time of every screen and the average quantization width Q1 based on the number of codes produced in every screen and the average quantization width. A function setter A 304 sets a function f:S=f(Q), and a function setter B 305 sets a function g:S=g(Q) passing the points (S1, Q1).  The intersecting point is calculated between the functions f:s=f(Q) and g:S=g(Q), and a quantization width decider 306 outputs the value of Q of the intersecting point as the quantization width.

Under this correction, a temperature corresponding to a difference of (a detected temperature of a surrounding air temperature sensing means 22)-(an operation set temperature of the output device 3 when the surrounding air temperature or its corresponding temperature is 0 deg.C) is added to a reference temperature, so that an operation setting temperature of the output device 3 is set low in case that the surrounding air temperature or its corresponding temperature is low and in turn if the surrounding air temperature or its corresponding air temperature is high, the operation setting temperature is set high. In addition, since this operation setting temperature corresponds to the case in which the surrounding air temperature or its corresponding air temperature is 0 deg.C, so that a degree of increasing in atmospheric air temperature in the heat exchanger 1 can be accurately detected in response to a variation in the surrounding air temperature.

Abstract: PURPOSE:To surely prevent winding and faulty separation of transferring paper and to surely prevent faulty transfer, etc., by specifying a distance from the position of a follower roller in the vicinity of a photosensitive body to a nip part where the photosensitive body and a transferring belt are opposed. CONSTITUTION:An output voltage V0 is changed in accordance with the change of a current at a bias roller 10.
