Title: Paper feeding roller
Inventor: NAKAMURA HITOSHI
IPC: B65H29/20
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce a diameter of a paper feeding roller, to improve precision, to reduce cost and to improve durability by forming the paper feeding roller on a base on a cylinder by covering it with a thin film of an elastic material and making a static friction coefficient and a dynamic friction coefficient against a copy sheet at the time when the copy sheet is not yet passed through the paper feeding roller in a specific range. SOLUTION: A paper feeding roller is formed by covering a cylindrical base 52a with a thin film made of an elastic material 52b. In this case, when frictional force of the paper feeding roller is low, carrier force to make a recording sheet bite into between the paper feeding roller and a pinch roller cannot be provided, and paper feeding failure is caused. Consequently, it is desirable that a static friction coefficient and a dynamic friction coefficient of the paper feeding roller are respectively more than 0.5.  Additionally, at the time when the static friction coefficient and the dynamic friction coefficient of the paper feeding roller are more than 1.0, sufficient carrier force can be provided, but as paper powder transferred to the paper feeding roller during carriage is not peeled off from a film surface, frictional force of the paper feeding roller is extremely lowered and paper feeding failure is caused. Consequently, it is desirable that the static friction coefficient and the dynamic friction coefficient of the paper feeding roller are less than 1.0.

Title: Detecting device of magnetism
Inventor: KISHIGAMI TOMOHISA
IPC: G01R33/06
Filed: 1988-09-23
Abstract: PURPOSE:To enable the amplification of magnetism so that a weak magnetism can be detected even by means of a Hall element, by a method wherein a magnetism converging body, which is a tubular pyramid formed of a superconducting material, is provided with a slit on the lateral side. CONSTITUTION:A pair of magnetism converging bodies 1 and 3 formed of a superconducting material are shaped in tubes of which the respective opening areas of ends 13 and 19 on one side are larger than those of ends 15 and 17 on the other side, and the ends 13 and 17 are made to communicate with the ends 15 and 17 by slits 5 and 7 respectively. A Hall element 9, which is a magnetic field detecting means, detects magnetism converged by the converging body 1. According to this constitution, a magnetic flux B entering from one end 13 of the converging body 1 is converged at the other end 15, since the converging body 1 is formed of the superconducting material and since the opening area of the end 13 is larger than that of the other end 15. As the result, the magnetic flux density at the end 15 is higher than that at the end 13. The magnetism is amplified accordingly, and even a weak terrestrial magnetism, for instance, turns to have a strength of magnetism large enough to be detected at the element 9.

Title: Automatic packaging apparatus
Inventor: FUJII NORIYASU
IPC: B65B51/10
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To save electricity required in such a step for changing kinds of articles to be packaged during a stand-by time by providing a control means that interrupts heating of an electric heater when a stand-by exceeds a specified period of time during a period of stand-by time at a delivery part whereto packaged articles are delivered from a packaging part. SOLUTION: In a control means 71 that controls entire operation of a tray packaging apparatus, a heater control program for a delivery part 13 that delivers packaged articles is included. So long as trays are supplied successively on the above-mentioned program within a time before start of electricity-saving, a packaging mode is executed. In the case where no tray is supplied for packaging, the temperature of an electric heater at the delivery part 13 is controlled under an electricity-saving mode, based on the temperature detected by a temperature sensor 33 at the delivery part, on passing over the time for starting electricity-saving after elapse of stand-by time.  Therefore, when stand-by between a preceding packaging motion and a succeeding packaging motion passes over the time for starting electricity-saving, the electric heater is not heated excessively during the stand-by after start of electricity-saving, and saving of electricity can be achieved.

Title: Copy protection system
Inventor: NAKAYAMA SABURO
IPC: G06F21/12
Filed: 1987-09-24
Abstract: PURPOSE:To attain the complete protection of copies by securing such a constitution where a specific number of an information processor stored in a ROM of this processor into a program and the program is carried out only by the information processor that has the coincidence between said specific number and a registered one. CONSTITUTION:The product number of an information processor is previously stored in a product number storing part 4 of a ROM 3 as a specific number of the processor. At the same time, the specific number, i.e., the product number of the information processor is registered at the program supplier side for a program supplied for storage into the processor. When the program supplied to a main memory 1 is loaded, a CPU 2 reads the product number out of the part 4 and collates this number with the product number registered into the program loaded to the memory 1. Then the program processing is continued when the coincidence is obtained between both product numbers. While the execution of the program is rejected when no coincidence is obtained between both product numbers. As a result, the execution is impossible for a program if copied illegally through the processors except the registered one.

Filed: 1986-10-08
Abstract: PURPOSE:To inhibit the backflow of intake air to prevent impact sound from being generated, by closing a bypass valve disposed in a passage bypassing a check valve in a high speed and high load operating range. CONSTITUTION:When a supercharger 5 is driven after an engine 3 is started, intake-air fed into an engine 3 through a supercharger bypass passage 9 since a supercharger bypass valve 10 and a bypass valve 8 are opened during low load operation. When the rotational speed of the engine 3 is increased to allow the operation of the engine to enter into a supercharging range, the supercharging bypass passage 9 is closed so that intake-air which has been supercharged by the supercharger 5 is fed into an engine 3. In a high speed and high load operation range in which the rotational speed of the engine 3 is further increased, the check-valve bypass passage 7 is closed.
