IPC: G06F12/00
Filed: 1986-03-13
Abstract: PURPOSE:To quickly perform processing by accessing an image memory for a number of times fewer than conventional to transfer data in an area of the image memory to another area or superpose data. CONSTITUTION:When data in an area A of an image memory 2 is transferred to an area B, a function signal inputted to a timing generating circuit 5 is read and cleared. Then, the output of an AND gate 9 becomes 0. In this state, the area A of the image memory 2 is accessed by an address A0-A24. Data in the area A is read out and is written on a save memory 10, and data 0 is written on the area A of the memory 2. The function signal is set to normal write, and a signal WE inputted to the memory 2 is set to the write-enable state. Data in the area A stored in the memory 10 is inputted to a terminal DOUT. At this time, the area B of the memory 2 is addressed by the address A0-A24 to write data of the area A on the area B.

Abstract: PURPOSE:To put pages effectively in order by feeding sheet originals again after copying operation by selectively switching a mode in which the sheet originals are discharged automatically after image forming operation and a mode in which an original conveying belt is put in successive feeding operation without operating an optical system. CONSTITUTION:A sheet original is placed on a tray 1 and then inserted between a pickup roller 3 and a paper feed roller 4. Then, a detection sensor 11 senses the original and a driving roller 13 rotates, starting the coneyance of the original a certain time later. A detection sensor 12 detects the front edge of the original, which is sent in between an entire-surface belt 15 and platen glass 47; and a detection sensor 11 detects the rear edge of the original and when the original is discharged, the roller 3 moves up. Then when the detection sensor 12 detects the front edge of the paper, the belt 15 stops and the original stops at a prescibed position of a platen 47. Then, copying operation starts and the original is discharged onto a tray 23 through discharging rollers 20 and 21 by a copying end signal. A necessary mode is selected with a mode changeover switch.

Abstract: PURPOSE:To smooth and ensure the feeding of a bar solder by providing the guide guiding a bar solder from a storage part to a solder tank and by arranging the storage tank by inclining in the same direction as the guide. CONSTITUTION:The bar solder storage part 1 storaging a bar solder 1 by its piling is provided by inclining in the same direction as that of a guide 6 and the chain 3 feeding out the bar solder 2 is arranged by inclining in the same direction as well.

Title: Manufacturing method for paste type lead positive electrode plate
Inventor: KOBAYASHI YOSHIHIRO
IPC: H01M4/62
Filed: 1983-03-30
Abstract: PURPOSE:To improve the sudden discharge characteristics of a paste type positive electrode at low temperatures by adjusting lead paste while containing a specified range of aluminosilicate soda for a lead powder compound and applying it to the support body of the positive electrode. CONSTITUTION:Aluminosilicate soda is mixed in a lead powder compound at a rate of 0.2-4wt% and is kneaded by adding water and the lead paste is adjusted by continuing kneading while adding dilute acid. In addition, a grid body made of a lead alloy is filled with it and a paste type positive electrode plate is formed by aging and drying. Thus, since aluminosilicate soda is porous and has an excellent property in the adsorption of positive electrode ions, it effectively actuates the move of a dilute ion and a lead ion at the charge and discharge of the negative electrode. As a result, the sudden discharge characteristics of the lead acid storage battery using this positive electrode can sharply be improved at low temperatures.

Abstract: PROBLEM TO BE SOLVED: To eliminate watering irregularity and to provide the effect of extending the flying distance of watering by bend-standing suspend-supporting rods and wide wings around a base plate constituting deflector and forming chamfers at the upper tips of all the wings so as to eliminate the dead area of watering generated by its own wings. SOLUTION: When a fire is generated, the heat sensitive panel of a heat sensitive means is fused to melt a fusible piece and tension between the reciliency of a spring and the heat sensitive means is eased to release a locking means to fall the heat sensitive means with the locking means at a moment by spring pressure. At this time, a valve body 9 is pulled out from a nozzle 13 and the deflector 7 also drops to suspend-hold all the wings 2 by remaining exposed. Fire extinguishing water discharged from the nozzle 13 intensely collides with the valve body 9 at first and starts to be sprashed on all sides but it is prevented by the wings 2 and the suspend-supporting rods 4 to raise internal pressure to intensely water from the gaps of the wings 2 and the suspend-supporting rods 4 so as to reach remote places and to water from the chamfers 3 provided at the upper tip parts of the wings 2 to remarkably reduce the dead zone.
