Title: Method and system for forming image
Inventor: ANDO TOMIO
IPC: B41J2/36
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for forming an image of higher quality by leading out the decreasing storage quantity of heat radiated from a thermal head heating part during interruption of printing operation thereby controlling heat storage of a thermal head according to an extremely simple correction equation derived from an unsteady thermal conduction equation because it is difficult to form a good image through a heat storage control where radiation of stored heat is estimated roughly. SOLUTION: In the image forming system performing thermal transfer recording using a pigment or a dye as a coloring matter while correcting an image data depending on the heat storage quantity of a thermal head at the time of recording, quantity of heat being stored in each heating dot is determined when application of the image data to each heating dot is interrupted according to an equation θ=exp(bτ) (θ; heat radiation rate and θ=1 when application of the image data is interrupted, τ; time when application of the imaqe data is interrupted, b; coefficient). Subsequently, the quantity of heat radiation is predicted and the image data is corrected.

Title: Coin processor
Inventor: MATSUDA EIJI
IPC: G07D9/00
Filed: 1987-10-26
Abstract: PURPOSE: To prevent malfunction caused it when a defective setting of a maximum storage number in coin pipes is in existence for carrying depositted coins into a safe by avoiding the carrying of the depositted coins to the safe. CONSTITUTION: A counter 10 sums depositted coins to coin pipes and subtracts paid-out coins from the coin pipes to calculate number of stored coins. In order to manage carrying excess coins to a safe, when a manager of an automatic vending machine sets an optional maximum storage number to a coin number setting device 10 and operates a switch 40, a controller discriminates whether or not the maximum storage number is number of coins received at maximum by one sales transaction by means of a safe carrying management discrimination device 51, and when the maximum storage number is the maximum receptible coin number or over, the controller is set to a safe share management mode.  The controller in the safe share management mode allows a safe introduction discrimination device 54 to activate a share device so that coins depositted more than the maximum storage number are led to the safe. Thus, a defect due to non-returned coins is avoided.

IPC: B29C33/44
Filed: 1992-10-09
Abstract: PURPOSE:To prevent scattering, a cracking of a molded form by allowing an ejector pin to protrude by controlling a pressure or a speed until releasing of the form is started, and then conducting it at a high speed while the form is dropped at a position, and allowing it to protrude with a small vibration after it reaches the dropped position. CONSTITUTION:When an operation of an ejector is started, a time T1 and a protruding pressure P0 are set, a protruding pressure control is preferentially conducted during the time T1 to prevent scattering, a cracking of a molded form. When an ejector pin reaches a releasing position, the form is released, a load is reduced, and a protruding speed is raised. Accordingly, an upper limit value V1 of the protruding speed is set. Then, a speed control until the pin is arrived at a molded form dropped position is preferentially conducted during a time T2, and the pin is allowed to protrude at a set speed V2. Then, a return of the pin at the dropped position is started, and the protrusion and the return are repeated. The protruding times T4, T5 and the returning times T3, T4 are desirably set to 0.05sec or less.

Title: Apparatus for opening closed flap of bag
Inventor: MIZUNO KENICHI
IPC: B65B43/38
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To reliably open a closed flap of a bag by setting a rotation center of a flap holding part aligned with a rotation center of the closed flap. SOLUTION: A cam follower support 46 is pushed/pulled via a joint 53 and a flexible member 52 by advancing/retreating operation of a piston rod 54 of an operation cylinder 48, and a cam follower 45 moves along a cam groove 49. As a result, a suction disk 41 rotates via a suction disk rod 51. Since the center of a rotation orbit of the suction disk 47 becomes a rotation center 50 of a flap 10A, since a center O1 of the cam groove 49 guiding a rotation of the cam follower 45 is set to be aligned with the rotation center 50 of the flap 10A. Thus when the suction disk 47 rotates with the flap 10A of an envelope 10 sucked, it functions, to the flap 10A, only opening force F perpendicular to a surface of the flap 10A. As a result, the flap 10A can be securely opened to approximately 90 deg. without the suction disk 47 disengaged from the flap 10A.

Title: Food container with heating function
Inventor: HAYASHIDA YOICHI
IPC: C08L101/16
Filed: 1993-10-29
Abstract: PURPOSE:To maintain the safety of users so as to ensure them against burn by forming a self burning type ignition agent from a binder consisting of a water-soluble cellulose derivative. CONSTITUTION:An ignition line 6 is obtained by immersing a linear object such as carbon fiber in a water-soluble binder solution of ignition agent consisting of oxidizing and reducing agents and drying it. The ignition line 6 is so constructed as to ignite by a spark generating device 9 and hinder the exothermic reaction of an exothermic agent 4, unless it burns up to this agent. A water-soluble cellulose derivative is necessary as a binder for forming a self burning type ignition agent. By way of example, this cellulose derivative may be methyl cellulose and hydroxypropylmethyl cellulose. Under the moisture which can normally occur, the exothermic agent is normally ignited to generate heat and, in a case where an excessive amount of water intrudes into an exothermic body storing chamber 2, the exothermic reaction is hindered by decomposition of the composition of the ignition agent or loss of its shape.
