Title: Image forming device of contact charging method
Inventor: MIZUSAWA MASAKO
IPC: G03G15/02
Filed: 1990-10-22
Abstract: PURPOSE:To prevent generation of charging nonuniformity due to attachment of toner on a charging roller and certainly carry out continuous rolling by forming a part to make contact with a non-image forming territory on the surface of a charging roller of a material having a larger coefficient of friction than that of a part to make contact with an image forming territory. CONSTITUTION:There is a core metal 11 of a conductive member forming shaft parts 11a on both sides, a non-adhesive film of a small coefficient of riction made of carbon dispersed lumifreon 12 is formed in a territory A corresponding to an image forming territory on the surface of a sensitizing body belt 1 on its outer periphery 11b, and a film of a large coefficient of friction made of urethane rubber 13 is formed in a territory B corresponding to an imaged formed territory. Consequently, even if contact pressure of a charging roller 5 and the sensitizing body belt 1 is comparatively small, the charging roller 5 certainly rolls continuously by a rotation of the sensitizing body belt 1. Additionally, as a part of the charging roller 5 making contact with the image forming territory is covered with the non-adhesive film, toner is attached to this part and it is possible to prevent generation of charging nonuniformity.

Title: Card reader
Inventor: TAKENOUCHI HITOSHI
IPC: G11B21/20
Filed: 1985-12-16
Abstract: PURPOSE:To allow the same card reader to process magnetic cards with different thicknesses by constructing a link mechanism transmitting the displacement of a detection roller to a pad roller. CONSTITUTION:When the magnetic card reaches the detection roller 41, said roller 41 descends or is displaced due to the card thickness. The link mechanism 42 consisting of two sway levers 44 and 46 displace the pad roller 4 by the card thickness as found to be approximately the same as the displacement quantity of the detection roller, whereby a clearance suitable to the card is formed between a magnetic head 3 and the roller 4. Thus the cards with different thicknesses can be stably pressed against the magnetic head, and magnetic information can be surely read and written.

Title: Lubricating oil additive and rolling process
Inventor: TAKAHAMA YOSHIHISA
IPC: B21B27/10
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To improve plate-out resistance by preventing generation of heat scratch of a metal to be rolled, by rolling the metal using the lubricant oil added with a specified 1,3,5-triazine-2,4-dithiol derivative thereto. SOLUTION: A 1,3,5-triazine-2,4-dithiol derivative represented by the formula (wherein R is a lipophilic functional group in which the functional group R is any one of an alkyl group, an alkenyl group, a phenyl group, a phenylalkyl group, an alkylphenyl group and a cycloalkyl group) is added to a lubricant oil used in rolling a metal. The 1,3,5-triazine-2,4-dithiol derivative has stronger adherence to a metal rather than a base oil component of the lubricant oil, and an SH group adheres to a roll and a material to be rolled in its orientated form. On that account, a thin film having thickness of several nm is formed on the surface of the roll and the material to be rolled, and plate-out resistance is improved due to an action of the film. Since the SH group is also a hydrophilic functional group, there is an emulsification effect in the case of making it an emulsion.

Abstract: PROBLEM TO BE SOLVED: To facilitate the retrieval processing or information management of missed issue and to improve the convenience in magazine management by generating missed issue data showing the missed issue or volume when it is judged that the arbitrary issue or volume is not accepted to the ordered magazine, and registering these data while relating them to order data. SOLUTION: A discrimination condition setting part 201 sets discrimination conditions for discriminating whether the arbitrary issue or volume is accepted to the ordered magazine or not. Based on the discrimination conditions set by the discrimination condition setting part 201, an acceptance discriminating part 202 discriminates whether the arbitrary issue is accepted to the ordered magazine or not. When the acceptance discriminating part 202 discriminates that the arbitrary issue is not accepted to the ordered magazine, a magazine volume number data generating/registering part 203 generates magazine volume number data containing the missed number information showing the relevant edition is missed, and registers the generated magazine issue (or volume) data in a magazine managing DB 104 while relating them with the order data.

Further, a comparing circuit 19 shapes the waveform by comparison with a reference voltage to obtain the vertical synchronizing signal separation output in an output terminal 21.

Filed: 1989-10-31
Abstract: PURPOSE:To reduce leakage current by performing time difference PWM control of power conduction interval for two inductive loads for the interval where they are excited simultaneously. CONSTITUTION:A PWM circuit 311 for first phase compares a first basic wave with a level signal corresponding to a current difference signal I1 and produces a PWM signal P1 which is then outputted as a power conduction signal G1. A PWM circuit 312 for second phase compares a second basic wave VR with a level signal corresponding to a current difference signal  I2 and outputs a PWM signal P2 which is then outputted as a power conduction signal G2. Consequently, transistors 181, 191, 182, 192 are turned ON and voltages V1, V2 are applied, respectively, on first and second phase motor coils 161, 162. But, since the power conduction signals G1, G2 are formed of the first basic wave Vs and the inversion thereof, i.e., the second basic wave VR, a time difference is provided between the voltages V1, V2 thus bringing them into unmatched state.
