Title: Pulse width temperature change compensating system
Inventor: MOTOI HIDESUKE
IPC: H03M5/18
Filed: 1984-09-06
Abstract: PURPOSE:To eliminate temperature changes in unipolar pulse by applying a voltage to a clock generating section used in applying bipolar/unipolar (B/U) conversion via a resistive element having a resistance change to compensate the change in the pulse width of the unipolar pulse in a predetermined temperature range. CONSTITUTION:A voltage +Vcc fed to a clock extraction circuit 5 is fed via a variable resistor 8.

Title: Combined getter material and method for evacuation hermetic space
Inventor: AONO FUMIAKI
IPC: B22F1/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to rapidly, easily and surely execute evacuation in spite of a hermetic space used in various kinds of temp. regions and in spite of the narrow and long hermetic space. SOLUTION: The combined getter material 2 consists of a first getter material which has a hydrogen dissociation pressure characteristic and is capable of absorbing hydrogen and a second getter material which covers this first getter material, has the hydrogen dissociation pressure characteristic higher than that of the first getter material and is capable of absorbing the hydrogen. The application of a poisoning resistant surface treatment on the combined getter material 2 is possible as well.  At the time of substituting the hermetic space with gaseous hydrogen, the combined getter material 2 prevents the absorption of the hydrogen and the second getter material on the outer side absorbs the hydrogen accompanying the subsequent temp. rise and temp. fall, by which the evacuation of the hermetic space is made possible as the hydrogen is absorbed by the first getter material on the inner side after the occurrence of cracks and destruction.

Title: Carrier roller
Inventor: YAMAMOTO KENJI
IPC: B65H5/06
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a carrier roller that can prevent the generation of a recessed part to paper on the assumption that it is made of plastic. SOLUTION: A carrier roller 13 is composed of an outer peripheral part 13a, a shaft part 13b, a mass removing part 13c and a connection part 13d, and the connection part 13d coincides with a die split face. A recessed part 13e is therefore formed in the die split face corresponding position of the outer peripheral part 13a, so that a burr generated at this part is held into a lower position than a flat part 13g of the outer peripheral part 13a so as not to come in contact with paper. Since both ends of the outer peripheral part 13a are tapered parts 13f, even though the carrier roller 13 is formed into drum shape due to molding shrinkage difference, no edge is generated to both end parts. With both ends of the outer peripheral part 13 formed into curved parts, paper can be conveyed, normally even though partial contact is generated to the carrier roller 13.

Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To cope with the high-speed operation of an image forming device by controlling the rotation of each developer carrying member so that the rotation is started immediately before the developer carrying member reaches the development position, to shorten the time loss. SOLUTION: An image forming device is provided with a drive control means to control the rotation of development rollers 10, 10R, 10B so that the rotation is started immediately before the respective development rollers reach the development position when a development unit 1 is rotated and the development rollers 10, 10R, 10B of development devices 3, 3R, 3B are positioned at the development position. Before the development roller 10, for example, is positioned to the development position, the developer 9 stored in a development chamber 4 of the development device 3 is stirred by the rotation of the development roller 10, and the toner and the carrier are charged.  Thus, even when the development action is started immediately after the development roller 10 is positioned to the development position, a visible image free from any background fouling can be formed on a photoreceptor drum 11.
