Title: Electrophotographic copying machine
Inventor: ITO KEIZO
IPC: G03G15/01
Filed: 1992-02-17
Abstract: PURPOSE:To improve 5 fixability at a color copying time without lowering the CPM value of white-and-black copying by providing a control means which sets the paper supply interval of the color copying time longer than that of the white-and-black copying time as for an electrophotographic copying machine by which the white-and-black copying and the color copying can be executed. CONSTITUTION:The copying machine is provided with a desk part 38 under a copying machine main body 1 being as a device to which a paper is supplied, a sorter 19 on the paper ejection side of the main body 1 and an automatic document feeding device 3 above the main body 1. At the multi-copying time that the plural numbers of sheets are successively copied, the paper is supplied one after another at the paper supply interval T which is previously set to the ROM 40a of the control part 40 based on relation between the CPM value. The interval T is previously set so as to become different at the white-and-black copying time and at the color copying time. That means, the paper supply interval T1 of the white-and-black copying time and the paper supply interval T2 of the color copying time are set so as to attain T1<T2. Then, the paper supply interval is automatically switched at the setting time of a color copying mode.

Title: Magnetic recording medium
Inventor: MIYAZAKI TAKAHIRO
IPC: G11B5/735
Filed: 1994-02-28
Abstract: PURPOSE:To improve traveling durability and preservable characteristic and to deal with a trend toward the shorter wavelength of recording wavelengths by adding a bis-benzene to a magnetic layer. CONSTITUTION:The bis(aminopropyl dimethyl silyl)benzene is added to the magnetic layer of a magnetic recording medium constituted by forming the magnetic layer mainly composed of ferromagnetic powder and a binder on a nonmagnetic material. The amt. of the benzene to be added is specified to 0.5 to 6 pts. wt. per 100 pts.wt. ferromagnetic powder. More preferably, at least part of the binder constituting the magnetic layer is formed of a vinyl chloride copolymer contg. 0.1 to 1.0mmol/g epoxy. As a result, the strength of the magnetic layer is enhanced and the traveling durability is improved. The release property of the magnetic layer from the base film surface is improved and adhesion of tacky adhesive matter on the surface of the magnetic layer during preservation of the recording medium in around state is prevented. The preservable characteristic is thus enhanced. A similar effect is obtainable with this method even if the method is applied to a back coat layer by changing the amt. of the bis-benzene to be added and the epoxy content of the binder.

Title: Data holding device
Inventor: INOMATA MOTOI
IPC: H02J9/06
Filed: 1982-02-26
Abstract: PURPOSE:To prevent the holding time of a nonvolatile memory from being shortened and to hold data securely by transferring the data to the nonvolatile memory and holding the data continuously by using a backup power source once a power failure occurs. CONSTITUTION:If a power source V is turned off at some point of time, the potential Vp at a point P obtained by dividing the power source V through resistances 7 and 8 also drops abruptly to zero. A Zener diode 6a, on the other hand, is supplied with a power source VDD which drops in level gradually, so the output signal E of a comparator 11 goes to ''L'' simultaneously with the power failure of the power source V. The output signal E of the power source interrupt detection circuit 5 goes to ''L'' to turn on a transistor 15 and the power source which drops in level gradually is outputted as a power source VCC through the diode 16 to secure the power source for a central processing unit 19, nonvolatile memory 28, etc., for a prescribed time after the power source V is turned off.
