Title: Processing circuit for signals which are generated in electromagnetic rotation sensor using variable magnetic resistance
Inventor: CHIESARIO CHIANCHI
IPC: H03K5/1536
Filed: 1989-11-24
Abstract: PURPOSE: To improve reliability by providing a stopping means for immediately disabling a logic circuit after a first comparing means transmits a related signal indicating the zero cross of a sensor signal to the logic circuit. CONSTITUTION: This circuit is provided with a stopping means E for immediately disabling a logic circuit D after a first comparing means A transmits a related signal V1 to the logic circuit D. A time range in which the logic circuit D is opened by the operated result of the stopping circuit E ends at a point of time (t)0 , and therefore, it substantially precedes a point of time (t)1 when the operation pulling of the circuit E ends. Then, disturbance by any pulse with amplitude larger than a threshold level S1 fetched in the 'open' state of the logic circuit D can be avoided. Thus, when another zero cross signal is generated between the points of time (t)0 and (t)1 , an error can be identified, and reliability can be improved.

Abstract: PURPOSE:To prevent an inclination of right and left side of the shelf member and enable the shelf to be moved with a low force by a method wherein a driving ear, a rotating gear, a sliding groove for slidably holding a sliding member and holding it and a rack engaged with a spur gear formed in a right and left deep direction in a refrigerator adjacent to the sliding groove are arranged. CONSTITUTION:A frame 2 is formed such that a spur gear 5, a driving gear 8 and a rotating gear 9 are covered from above and below from within the refrigerator. When a shelf 1 is moved up or down, at first a dial 6 is rotated to cause a dial shaft 7 and the driving gear 8 to be rotated. Thus, the rotating gear 9 engaged with the driving gear 8 is rotated and then a gear shaft 4 and both side spur gear 5 are rotated. At this time, the spur gears 5 are moved while being engaged with the rack 14b through the gear shaft 4. Since the right and left spur gears 5 are fixed to the gear shaft 4 and rotated in the same direction, it is moved up and down at the right and left sides of the frame 2, i.e., the shelf 1 and no displacement of the right and left heights is produced. Under a state in which the shelf 1 is stopped, the driving gear 8 and the rotating gear 9 may form a stopping mechanism and even if foods are placed on the shelf 1, the shelf, may not be lowered.

Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To limit electron rays that contribute to image formation so as to enhance resolution by aligning at predetermined intervals the high- and low- electron-transmissivity parts of a conductive material layer on an output screen. SOLUTION: A phosphor layer 2 is provided over a glass plate 3 as an output screen 25, and a conductive material layer 11 is provided thereover. Generally, aluminum is used as the conductive material.

The recesses 11b are formed with film thicknesses small enough so that thier electron transmissivity is high. Thus emissions from the phosphor can be restricted only to those electrons which transmit through the high-electron-transmissivity thin-film recesses 11b at small angles.
