Title: Outdoor bushing
Inventor: AKIYAMA TOSHIO
IPC: H01F27/04
Filed: 1986-12-11
Abstract: PURPOSE:To obtain a bushing which does not cause the tracking even during the use in an area where many particles are floating in the air by a method wherein a dust shield is installed at the outer circumference near a part where an air-insulating tube for the bushing is grounded. CONSTITUTION:A dust shield 4 is installed at the outer circumference near a part where an air-insulating tube 1 for a bushing a grounded. For example, the dust shield 4 which is composed of an insulating material such as a synthetic resin material and whose horizontal cross section is circular is fixed to the outer circumference at the part where the air-insulating tube 1 is grounded near a metal support 2. An appropriate number of weep holes 7 are made at the bottom face of the dust shield 4. In addition, at the dust shield 4, a taller part 5 is formed at the windward side while a smaller part 6 is formed on the leeward; the dust shield is fixed to the metal support 2 in such a way that the taller part 5 faces the direction where a contamination source such as an iron mill or the like is situated or where the percentage to line on the windward side is high throughout a year. By this method, it is possible to effectively shut out electric-conductive substances in the air which come flying by wind currents and to prevent the substances from adhering to the surface of the air-insulating tube. As a result, it is possible to prevent the tracking form occuring.

Title: Method for growing single crystal
Inventor: KOUDA HIKARI
IPC: C30B29/22
Filed: 1993-11-25
Abstract: PURPOSE:To grow a high-quality single crystal of beta-barium borate (beta-BaB2O4 hereinafter abbreviated to BBO) according to a pulling up method. CONSTITUTION:This method for growing a single crystal is to grow the single crystal so as to provide the (113) face as a crystal habit and thereby enable a growth interface to change into a downward convex shape in growing the BaB2O4 single crystal 4 from a melt 2 having the composition of the BBO according to a pulling up method. For that reason, the production of a micro- angle grain boundary can be suppressed to grow the high-quality single crystal 4.

Title: Magnetic recording and reproducing device
Inventor: UEDA MIKIYA
IPC: G11B15/61
Filed: 1989-11-14
Abstract: PURPOSE:To prevent the gnawing of a magnetic tape even when a guard panel is closed after unloading is completed by making a revolving speed of a rotary drum under the unloading state smaller than a revolving speed of the rotary drum under the loading completion state. CONSTITUTION:With regard to the magnetic recording and reproducing device for performing the recording and reproducing by rotating the rotary drum 4, the revolving speed of the rotary drum 4 under the unloading state is made smaller than the revolving speed of the rotary drum 4 under the loading completion state. Consequently, since the revolving speed of the rotary drum 4 at the time of completing the unloading is diminished, air pressure to be generated from the rotary drum 4 is also diminished, thus diminishing influence upon the magnetic tape 7. By this method, the taken-up magnetic tape 7 is not waved, and even when the guard panel 6 is closed, the magnetic tape 7 is not gnawed.

Title: Composite local area network
Inventor: HATANO SATOSHI
IPC: H04L69/40
Filed: 1988-11-25
Abstract: PURPOSE:To simply and effectively prevent the isolation of a branch line network mainly due to a fault of a connection node by adopting the constitution of at least a couple of branch line networks among plural branch line networks such that the network couple uses a communication node including a transmission line changeover switch in common. CONSTITUTION:A communication node 7 is provided, which is used in common by branch line networks. An optical signal sent from a precedingly located node via a transmission medium 3c-41 to the node 7 passes through an optical switch circuit 10 and is sent to a medium 3c-43. On the other hand, the optical signal sent from the precedingly located node via a medium 3d-11 passes through the circuit 10 and is sent to a medium 3d-13 and each node makes independent communication. If a connection node 4c is faulty, network management information is sent to a control section 9 from a master node 1c via a node 8c, the circuit 10 is changed over and an optical signal in the medium 3c-41 is sent to a medium 3d-13. Thus, the connection node 4d is utilized and the signal is connected to a trunk line network to prevent the branch line networks from being isolated.

IPC: H01L21/66
Filed: 1990-10-31
Abstract: PURPOSE:To measure life time in an arbitrary semiconductor element pattern by converging a laser beam according to the semiconductor element pattern and then exciting only carriers. CONSTITUTION:A semiconductor substrate 6 is irradiated with microwave through a circulator 2 and carrier exciting laser is pulsated through an oscillator 5 and converged through a controller 15 to be impinged on the substrate 6 with a laser spot diameter corresponding with the magnification power of a variable magnification power lens 13. Carriers are excited at a part on the substrate 6 irradiated with the laser beam and when the laser output is zero, number of carrier reduces through recombination of carriers thus reducing the intensity of reflected microwave fed from a detector 8. Output from the detector 8 and reference pulse wave from an oscillator 5 are fed to a PSD(Phase Sensitivity Detector) 16 where only such component as having same frequency as the pulse wave is amplified and employed by a computor 10 for the measurement of life time.

IPC: H04N5/445
Filed: 1985-12-24
Abstract: PURPOSE:To prevent disorder in a picture when a television signal fades away from occurring by providing a retriggerable one-shot circuit to output a pulse of a pulse-width longer than the period of a vertical synchronizing signal and a flip-flop circuit to generate a signal to specify the internal picture mode against a gate circuit. CONSTITUTION:The external vertical synchronizing signal EV is repeatedly outputted from a separator circuit 42 with a period of 16.6mS, and the signal EV repeatedly triggers the one-shot circuit 44. The Q-output of the one-shot circuit 44 is inputted to the clock terminal of the flip-flop circuit 46. When a video signal form a terminal 10 is faded away, the signal EV from the circuit 42 fades, the one-shot circuit 46 is no longer cleared, and Q-output and Q'-output comes to L/H respectively, after a lapse of time of 3X16.6mS. This phenomenon functions as a data fetching command signal against the one-shot circuit 46, hence the said circuit fetches an H-level data, and its Q-output comes to H. Accordingly, the output MCS' of an OR gate 48 is made H, and the superimposing mode turns to the internal picture mode.
