Filed: 1988-10-24
Abstract: PURPOSE:To perform auxiliary exposure for a medium sheet with simple constitution by providing fuse type lamps opposite to the exposed surface of the medium sheet before colorless dye leaks out so that their filament parts have no lengthwise gap. CONSTITUTION:Many fuse type lamps 11 are arranged on the bottom surface of the auxiliary exposure device in three arrays in an X direction as the conveyance direction of the medium sheet. The length l of the filament parts 12 is shorter than the overall length L of the fuse type lamps 11.

IPC: G06F1/18
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To provide the hot-line inserted and extracted board which can reduce a rush current without increasing the oscillation and scale of the power source and making the device large-sized. SOLUTION: Power source feed patterns 2 to 4 are so divided that power source feed patterns feeding electricity to a package 1 respectively have nearly equal current consumption. A power source connector 5 is composed of power source pins 5a to 5c which are different in length. The power source feed patterns 2 to 4 and power source pins 5a to 5c are connected electrically while made to correspond to each other one to one. Consequently, the power source feed patterns 2 to 4 feed the electricity with time differences through the power source pins 5a to 5c, so the rush current is reducible.

Title: Fifo memory
Inventor: KUROKAWA HIDEFUMI
IPC: G06F5/06
Filed: 1987-10-22
Abstract: PURPOSE:To continue the cycle of a DMA and to attain the data transfer at a high speed by showing that an access permitting signal can access from an external part twice while a busy signal is active. CONSTITUTION:In an initial condition, an access permitting signal generating circuit 107 becomes active and 1 is outputted as an access permitting signal 109. Thereafter, a busy signal 108 is inputted from a DMAC, accompanying the writing of a DMA, effective data are written to a data latch 101 and simultaneously, the output of a flip flop 104 becomes 1. For an access permitting signal generating circuit 107, since the busy signal 108 is active, the output of a flip flop 105 is 0 and the access permitting signal 109 is kept active still. Thus, in the first bus cycle, since the access permitting signal 109 continues to keep 1, the DMAC does not deliver the bus in the next DMA cycle and continues the DMA, the high speed data transfer can be executed.

Title: Capacity control device for rotary compressor
Inventor: SUZUKI AKIRA
IPC: F04C29/04
Filed: 1984-12-21
Abstract: PURPOSE:To prevent the temperature rising of discharge air from a compressor at the starting of its unload operation by increasing the blow-off quantity of a blow-off valve mounted between a compressor and a check valve on its delivery side for a fixed time when the compressor has been shifted from the load operation to the unload one. CONSTITUTION:When a pressure switch 7 detects decrease in working air quantity, three-way solenoid valves 8, 9 are switched over to start the unload operation of the compressor. In this case, an unloader valve 15 interlocks with a blow-off valve 14, and discharge air existing between the compressor 3 and a check valve 5 is exhausted through a blow-off piping 12 in the atmosphere. At the same time, a blow-off solenoid valve 11 opens for several seconds to quickly reduce pressure in a discharge piping. Thus the abnormal temperature rising of the discharge air at the starting of the unload operation can be prevented.
