Title: Voltage drop detection circuit
Inventor: KAMATA SEIJI
IPC: H02H3/24
Filed: 1982-05-11
Abstract: PURPOSE:To detect voltage to be inspected with limited number of MOS transistors by OR combination of both output signals from first and second complementary MOS type differential amplification circuits to make a detection signal. CONSTITUTION:Both differential amplification circuits are made up of pairs of complementary MOS transistors as indicated by 19-26. An OR circuit 27 receives output 12 of the differential amplification circuit 2 and the output 11 of the differential amplification circuit 1 and gives a detection signal of a power source voltage detection circuit at the output terminal 28. In operation, when the power source voltage drops, threshold voltage of a P-channel type transistor 16 is detected and the signal at the output terminal 11 of one different amplification circuit 1 changes from the level 'L' to the level 'H'. Threshold voltage of an N- channel type transistor 18 is detected and the signal of the output terminal 12 of the other amplification circuit 2 changes from the level 'L' to the level 'H'. The detection of the power source voltage drop is performed based on a higher absolute value between threshold values of the P-and N-channel type transistor.

Abstract: PURPOSE:To easily constitute the disk loading device corresponding to disks having respectively different diameters by providing two ridgelines opened like a V shape in the direction to a turn table on a main plane perpendicular to the rotational shaft of the turn table on the lower part of a disk guide plate. CONSTITUTION:Although the V-shaped two ridgelines are formed in the direction to the turn table 6 on the lower part of the disk guide plate 5, a 12cm-disk (12cm CD) 15 inserted from a disk inserting port 3 is driven in the horizontal direction without being influenced by the ridgelines and abutted upon a stopper 14 as shown by an alternate long the two short dashes line to regulate the depth of insertion and execute centering. In the case of inserting an 8cm CD 17, the CD is inserted in the horizontal direction up to the way of the insertion, but the CD 17 is driven upward because of the existence of the V-shaped ridgelines and abutted upon a stopper 16 as shown by an alternate long and two short dashes line, so that the regulation of insertion depth and centering can be executed. Since the stoppers 14, 16 can be fixed on different heights corresponding to CDs having different diameters, the disk loading device can be easily constituted.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To efficiently pack and embed refuse and to treat the more refuse by effectively utilizing the same not only on the ordinary ground out at a waste disposal plant which is already nearly full. SOLUTION: This refuse treatment method uses an excavated sand and soil compaction type auger constituted by providing the outer periphery of an auger rod 3 with an ironing section 5 having a curved pressing surface 4 overhanging outward from the rod 3 so as to spirally ascend in the rotating direction of excavation. The, sand, soil, etc., excavated by the auger are pressed outward and compacted to an extrusion hole wall 11 by the ironing section 5, by which a hole is drilled while the sand and soil are substantially not discharged above the ground. The refuse 16 (or the refuse and the sand and soil) is charged into the hole 15 from a hole part 15a while such excavated sand and soil compaction type auger is kept rotated reverse from the rotation at the time of excavating the hole in the state of inserting the auger into the hole 15.  While the refuse 16 (or the sand and soil) is dropped onto the hole bottom 15b, the refuse, etc., are compacted to the hole wall 11 by the ironing section 5. The excavated sand and soil compaction type auger is pulled while the remaining refuse, etc., successively accumulating on the hole bottom 15b are tamped and packed by the auger head 2 at the front end of the excavated sand and soil compaction type auger.

Abstract: PURPOSE:To prevent the movement of an original platen during the transportation of such a type of copying machine that the original platen is movable by providing a lock means to the copying machine frame. CONSTITUTION:The lock means 30A at the side of the copying machine frame 1 is equipped with a bracket 31, lock piece 32, leaf spring 33 which presses up the lock piece 32, and guides 34 and 35 fixed to a cabinet 24.

Title: Fuel injection system
Inventor: KIMATA KEI
IPC: F02D41/34
Filed: 1979-06-25
Abstract: PURPOSE: To improve responsiveness in fuel control by achieving conrrection of the standard air-fuel ratio of a fuel injection system only through of the pressure difference in a differential pressure regulator.  
     CONSTITUTION: On-off control of a solenoid valve 25, disposed on the upstream side of throttle valve 27, is accomplished on the ratio of time duration of "rich" signal and "lean" signal relating to air-fuel ratio, produced from sensor 30 which detects the operational condition of engine. If the time length when solenoid valve 25 is closed is increased, pressure PL in chamber C, acted to diaphragm 18 in differential pressure regulator 3, is lowered, which results in lowering of pressure PF in chamber a, so that air-fuel ratio can be corrected to a richer side. On the other hand, if the time length when valve 25 is closed is decreased, air-fuel ratio can be corrected to a leaner side. Therefore, the time required for correcting air-fuel ratio to suit the engine operation can be shortened as compared with that required in the conventional systems, so that responsivness of fuel control can be improved.

CONSTITUTION:A motor 18 is operated to move a top roller 6 upward to the position where it does not collide against squeeze rollers 1, 1. The belt 19 of a motor 15A located on the attaching and detaching end side is dismounted, after which a clamping device 17 is removed and a casing 13 is slided with respect to a base 16. The screw shaft 20B located on the counter attaching and detaching end side is pulled from a gear 23 and the base 16 is slided while held screwed with a feed nut 21b, thereby permitting the sliding of the casing 13.
