Title: Image forming device
Inventor: ODA MASATAKA
IPC: G03G21/00
Filed: 1986-11-05
Abstract: PURPOSE:To securely supply carriers to the surface of a photosensitive drum by providing a carrier supply mechanism which increases the sticking force of magnetic carriers to an electrostatic latent image carrier and supplies the carriers to the surface of the electrostatic latent image carrier. CONSTITUTION:The carrier supply mechanism 30 has a solenoid 31 fixed on the side part of a developing device, and when the solenoid 31 is in an 'off state', the magnetic pole N1 of a magnetic roller 12 faces the photosensitive drum 1 and the intensest part P of lines of magnetic force produced by the magnetic pole N1 faces a development area X. When the solenoid 31 is in an 'on state', on the other hand, the weakest part Q of the magnetic force faces the area. Consequently, the sticking force of the magnetic carriers held at the part opposite to the electrostatic latent image carrier is increased and the carriers are supplied t the surface of the electrostatic latent image carrier.

IPC: G06F12/02
Filed: 1990-10-01
Abstract: PURPOSE:To read out the data of continuous addresses at a high speed by providing a counter for showing an address of serial data, an address register for storing the head address of the serial data, and a comparator for comparing the head addresses of the serial data. CONSTITUTION:A processor 1 writes an address 11 of the head address of data in a register 3. In this case, a counter 2 outputs a display data address 12 for showing an address of display data 8 outputted from a serial port of an image memory 6 to a comparator 4 and the image memory 6. The comparator 4 always compares the display address 12 and a value of the register 3 for storing the head address of data to be read out. As a result of comparison by the comparator, in the case the counter 2 and the register 3 become the same address, a data write control signal 14 is outputted, and the display data 8 is written in an FIFO 5. Simultaneously, a comparing signal 9 is outputted to the processor 1 from the comparator 4, and the device 1 reads out data 10 from the FIFO 5.

Title: Formation of aluminum electrode foil for electrolytic capacitor
Inventor: MATSUDA YOSHITAKA
IPC: H01G9/04
Filed: 1988-10-20
Abstract: PURPOSE:To obtain a sufficient capacitance in a high-voltage region by a method wherein a specific amount of gallic acid is added to an electrolyte in order to chemically form an aluminum electrode foil. CONSTITUTION:Zero point two g or higher, more preferably 0.5g or higher, of gallic acid is added to 1l of an electrolyte having a property to generate a voltage-resistant oxide film by anodic oxidation; an anodic oxidation operation is executed. That is to say, the gallic acid dissolves aluminum hydroxide which is generated on the surface of an aluminum foil and which is not resistant to a voltage; accordingly, a chemically formed coating is made thin and a capacitance is increased. Thereby, it is possible to obtain an aluminum electrode foil whose capacitance is large even in a high-voltage region.

Filed: 1990-10-01
Abstract: PURPOSE:To ensure the thermal welding between a main separator and an auxiliary separator by separating the heating part of a tooth-shaped upper heater from the heating part of a lower heater by net shorter than 10mm. CONSTITUTION:When a separator is sandwiched between a tooth-shaped heating part and a flat surface or tooth-shaped heating part, the area pressure of the entire heating part can be increased. Namely, an interval (h) between a tooth- shaped upper heater 1 and heating parts 1a, 1b of a lower heater 2 is defined no less than 10mm, while the heating parts 1a, 1b are heated, and a main separator 3 and an auxiliary separator 4 are arranged in the middle. The upper and lower heaters 1, 2 are put closer with each other, so as to sandwich the main separator 3 and the auxiliary separator 4, which are thermally welded. When the main separator and the auxiliary separator are welded in this manner, since the area pressure of the entire heating surface is increased, the separator of large welding intensity can be obtained.
