Title: Switching regulator circuit
Inventor: MINAMISHIMA MAMORU
IPC: H02M3/28
Filed: 1982-12-02
Abstract: PURPOSE:To allow the voltage level to coincide with the prescribed level by detecting the voltage level of positive and negative DC voltages due to variations in a load, and controlling the ON and OFF periods of a switching circuit on the basis of the difference between the level and the prescribed level. CONSTITUTION:A pulse width of the constant frequency pulse signal is set from a switching regulator control circuit 20 so as to become in their absolute values the prescribed equal level in the state that the levels of positive and negative DC voltages outputted from output terminals 8, 9 of a rectifying and smoothing circuit 21 are in no load. The control circuit 20 outputs the constant frequency signal having a pulse width to set the level of the DC voltage having larger level decrease in the absolute value as the set level from the output terminals 4, 5 in push and pull manner, thereby controlling switching transistors Q5, Q6. In this manner, it is controlled so that the absolute value voltage having smaller absolute value of the level always coincides with the prescribed voltage value.

Title: Electronic equipment
Inventor: NAKAMURA YOICHI
IPC: G06F11/00
Filed: 1986-09-09
Abstract: PURPOSE:To shorten the system recovery time after a power supply is suddenly cut off by holding the cut-off of the power supply in an off-line state despite occurrence of abnormality as long as a logical connection is secured with another equipment. CONSTITUTION:An on-line/off-line setting means 9 is kept away from an off-line state until the end of connection despite occurrence of abnormality as long the means 9 is connected logically to another equipment. A power supply control part 5 cuts off a power supply after an off-line state is set by the means 9. In other words, the off-line state is inhibited while the logical connection is secured with another equipment and an under-communication mode is shown. Then the off-line state is set after the end of communication and said logical connection. Thus it is possible to avoid an abnormal separation from another equipment in a communication mode and therefore to ensure the quick recovery of troubles for the entire system including software.

Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent character display tube capable of reducing areas not contributory to display and having a high degree of freedom of pattern design and high brightness efficiency. SOLUTION: A grid electrode 22 comprises a mesh-like grid electrode 22 which covers a phosphor layer 20 and whose peripheral edge part is fastened to a top part of a peripheral rib-like wall 44 provided on the peripheral side of, so as to project higher than, and so as to surround at every luminous unit, the phosphor layer 20. Electrons are controlled by the grid electrode 22 covering the phosphor layer 20, and therefore limitation on design and necessity to make a cut-off bias stronger as the area becomes larger, which take place when a rib-grid electrode is used, are not caused. Because a pad for use with grid for fixing a leg part of the grid electrode 22 is no longer needed, non-luminous areas can be reduced.  Further, because the phosphor layer 20 is separated from another one by the peripheral rib-like wall 44. leakage light emission caused by electrons having passed through the grid electrode 22 coming in a neighboring phosphor layer 20 cannot be produced.

Title: Long-sized object take-up device
Inventor: MATSUMOTO TOSHIYA
IPC: G03B21/11
Filed: 1990-08-14
Abstract: PURPOSE:To enable positive winding by disposing a face formed by the axial center of a take-up reel and a carrier face by a carrier roller in such a way as not to be vertical so as to restrain the end part of a long-sized object from being brought into contact with and caught by a reel protrusion. CONSTITUTION:A carrier roller shaft 12 and a take-up reel shaft 7 are disposed not in the parallel state but in the torsional relation by an angle alpha. A flexible joint is interposed between a motor shaft and the roller shaft because of their unparallel disposition. The width direction cross section of a film F started to be wound on a reel 3 from a carrier roller 1 is placed in the inclined state in relation to the reel 3 as the distance from a reel core 6 is enlarged, and the width C of the film F is narrowed as indicated by C' with the increase of the distance from the core 6. The film F is not therefore easily caught by the protrusion 3b of the reel 3 with the increase of its distance from the core 6. The film F can be therefore taken up by stable rotation and also is prevented from being damaged.
