Title: Positioning control system of magnetic head
Inventor: KONNO KAZUTOSHI
IPC: G11B5/596
Filed: 1984-09-21
Abstract: PURPOSE:To eliminate decrease of recordable data signals by record of servo signals by detecting positioning error of a magnetic head once every rotation of a magnetic disk and making closed loop servo. CONSTITUTION:One index pulse 21 is generated in every rotation of a magnetic disk, and a servo signal consisting of burst signals A, B is recorded alternately deviating by 1/2 track pitch from data recording tracks n, n+1-. When a magnetic head 11 that reproduces track n+1 deviated upward, regenerative amplitude of the signal A decreases, and regenerative amplitude of the signal B increases. On the other hand, reproducing output is inputted from the magnetic heard 11 to a positional deviation detecting circuit 13. Direction and amount of positional deviation of the head 11 is detected by finding difference of amplitude of burst signals A, B, and fed back to a step motor 7 through a comparator 17, an amplifier 18 and a driving circuit 19. It is enough to record the servo signal at one place in every recording track at specified part in circumferential direction of the magnetic disk.

Filed: 1994-08-22
Abstract: PURPOSE: To provide an apparatus for detecting a shortage of a refrigerant in a refrigerating cycle, capable of accurately detecting the shortage of the refrigerant without being influenced by an external air temperature. CONSTITUTION: When a refrigerant flow exceeding a predetermined flow rate advances along a refrigerant pipe as a refrigerant compressor starts its operation, a slide valve 21 fitted slidable in a guide 20 is subjected to the refrigerant flow to be thereby moved from an initial position to a displacement position, and, in the case where the refrigerant flow does not reach the predetermined flow rate, the slide valve 21 is stopped at the initial position by repulsion that works between a first permanent magnet 22 held by the slide valve 21 and a second permanent magnet 23 held by the guide 20. However, when the slide valve 21 is located at the initial position, clearances (a), (b) are set so that a small amount of the refrigerant can pass therethrough.  Accordingly, an apparatus for detecting the shortage of a refrigerant is constructed so that the refrigerant flows while the slide valve 21 is being kept in the state that it is stopped at the initial position in the case where the flow rate of the refrigerant circulating in a refrigerating cycle at the time of a shortage of gas is less than a predetermined flow rate.

Title: Liquid crystal display element
Inventor: KAWAOMO YOSHIAKI
IPC: G02F1/1339
Filed: 1986-08-26
Abstract: PURPOSE:To prevent the malfunction due to static electricity by allowing the first and second transparent electrodes to face each other in a seal part and setting the resistance value between electrodes due to a seal material to a value smaller than that due to a liquid crystal. CONSTITUTION:Since a segment electrode 21 does not face a common electrode 12 in a display part, it is necessary that a common electrode 11 and the segment electrode 21 face each other in the seal part, but it is unnecessary that the common electrode 12 and the segment electrode 21 face each other there. Segment electrodes 22-29 other than this segment electrode 21 face common electrodes 11 and 12, and it is necessary that they face each other in the seal part. In this seal part, the resistance value between electrodes due to the seal material is made lower than that due to the liquid crystal. Thus, the electric charge is discharged more through the seal than the liquid crystal when the electric charge due to static electricity is accumulated, and erroneous display is quickly erased.
