IPC: H02K9/22
Filed: 1978-12-06
Abstract: PURPOSE: To prevent the generation of vapor blocking and to improve the cooling effect by sealing a cooling liquid in the hollow rotary shaft and by providing a wick with multiple holes to the inner wall of the rotary shaft.  
     CONSTITUTION: The rotary shaft is made up in the form of a hollow double-pipe structure of both the hollow metal pipe 2 and the outer pipe 16, a cooling liquid 5 to transfer heat produced in the rotor core 9 to the radiating fin 10 is sealed in the shaft. The wick with multiple holes 17 is attached to the inner wall of the shaft on which the core 9 is mounted. In this way, the wick is not floated since bubbles 4 produced on the inner wall of the metal pipe 2 come out through the holes 17, the production of vapor blocking can be prevented, the cooling effect can be improved since the area of wick with a bad heat transfer ability is made less.

Abstract: PURPOSE:To increase the luminance of a charge-metastasis-type plasma display panel by forming on areas of the upper surface of a back base plate for a panel other than those on which second transition electrodes are formed, a pattern of thin metallic films which do not touch the transition electrodes. CONSTITUTION:A transition electrode group consisting of parallel thin metallic films coated with dielectric films is formed on the lower surface of a front base plate for a panel. Transition electrodes 4B and 4D consisting of parallel thin metallic films coated with dielectric films 5 are formed on the upper surface of a back base plate 3 for the panel. The electrode groups are placed with a gas space allowed between them in such a manner as to cause each electrode of the electrode group of the front base plate to correspond to a space formed between two adjacent electrodes of the electrode group of the back base plate, thereby forming a discharge space. A charge-injection electrode is installed at one end of the transition electrode group and a charge-erasing electrode is installed at the other end of the transition electrode group. On the other areas of the upper surface of the base plate 3 on which the electrodes 4B and 4D are not formed, thin metallic film patterns 4E which are not connected to the electrodes 4B and 4D and are not covered with any dielectric films 5 are formed.

IPC: G01S11/14
Filed: 1988-06-20
Abstract: PURPOSE:To obtain synchronization simply and accurately by sending a synchronizing signals to a pinger by using a transmitting coil and a receiving coil, resetting a first clock in the pinger, and synchronizing the first and second clocks. CONSTITUTION:A switch 24 for commanding synchronizing signal generation in a main body 10 of an apparatus is made to be an ON state. Then an electromagnetic power generator 25 generates a synchronizing pulse based on the output of a clock 17, and a magnetic field is generated around a transmitting coil 12 through a cable 26. The magnetic field passes through a water-pressure resisting container 50, and electromotive force is generated across a receiving coil 32 in the inside. The electromotive force which is generated in the receiving coil 32 is amplified to a constant level in an amplifier 36. When the lever exceeds a preset level, the regenerated synchronizing pulse is outputted from a level detector 37. The synchronizing signal resets a clock 39 through an AND gate 38. Since both clocks 17 and 39 are set at the same time in this way, the synchronization operation is finished when only the transmitting coil 12 is lifted over the water.
