Inventor: KANEKO SHINJI
IPC: H04N7/01
Filed: 1983-07-30
Abstract: PURPOSE:To prevent the flicker of a reproduced picture by suppressing the increase in luminance generated at a video signal portion obtained through the image pickup of a video camera having a different field frequency for the reproduced picture by means of a system converting synchronizing signal. CONSTITUTION:In image picking up the reproducing picture of the HDVS system by the video camera 3 of the PAL system and in conducting the system convertion for the video signal, the signal reproducing device 1 of the HDVS system is synchronized by the system converting synchronizing signal having a frequency being 1/5 of the field frequency of the video signal obtained from the camera 3 so as to synchronize the signal to the synchronizing signal of the HDVS system. Thus, the luminance of the determined field of the video signal of the PAL system is increased and the signal level of the video signal converted into the PAL system is made constant by applying AM modulation only to said field based on said synchronizing signal in an AM modulation circuit 5 so as to prevent the flicker of the reproduced picture.

At this time, an outer wall of the connection wall surface 19 is set down to a hitting surface of the stem 17, and the stem 17 is formed in conformity with a form of this hitting surface. According to this method, when selection of a gas flow takes place, capacity at the valve rear stream side is sufficiently filled up with a gap between the stem 17 and the connection wall surface 19 whereby the clearance can be brought to zero in substance. Therefore, gas before valve selection is preventable from mixing in that after being selected.

Filed: 1988-06-09
Abstract: PURPOSE:To improve high-temp. strength and hygroscopic resistance by incorporating specific ratios of Si3N4, MgO and Al2O3 into BN and specifying the size of the crystallites of the BN. CONSTITUTION:This sintered body of boron nitride consists, by weight %, of 2-10% Si3N4, 1-3% MgO, 1-3% Al2O3 and, the balance BN and the size (LC) of the crystallites of the BN is 150-400Angstrom .

The Si3N4 of this sintered body has the effect of suppressing the growth of the BN crystals. Said effect is not exhibited if the ratio of the addition thereof is below 2%. The content of the BN decreases and the characteristics of the BN are lost if the ratio exceeds 10%. Since the Si3N4 has a poor self-sintering property, the MgO and the Al2O3 play the role of assisting the sintering of the Si3N4 as well.

Title: Ferroelectric liquid crystal electrooptical element and driving method thereof
Inventor: NAKAMURA TOYOICHI
IPC: G09G3/36
Filed: 1990-05-30
Abstract: PURPOSE:To obtain a simple medium contrast display with a simple matrix type at a good production yield by using a ferroelectric liquid crystal which has just one stable state and determining the orientation bearing of the liquid crystal in this stable state as a uniaxial orientation direction. CONSTITUTION:This liquid crystal electrooptical element is constituted to hold the liquid crystal 8 in place between two sheets of substrates 5 formed with electrodes 6 and oriented films 7 and to be further provided with polarizing plates 10 on the substrate surfaces. Since the single stable orientation state is used in this case, the intermediate state is maintained by using a proper AC voltage after an inversion voltage. A liquid crystal material having large dielectric constant anisotropy is required to maintain the intermediate state by overcoming the orienting force tending to return the above state to the single orientation state by the AC voltage. Multidivision is possible in this way and the medium contrast display is obtd.

Title: Tap change-over transformer when loading
Inventor: ONO MASARU
IPC: H01F29/04
Filed: 1977-11-24
Abstract: PURPOSE: To ensure the little applied voltage of a shunt reactor and the low magnetic flux density of a core, by dividing an exciting winding into two portions, and by connecting the shunt reactor to the earthing side.  
     CONSTITUTION: In a tap change-over transformer when loading for operating two tap changers 6A, 6B in parallel, a winding is divided into two portions of exciting windings 11A, 11B, and a shunt reactor 10 is connected to the earthing side. Thus, circulating current is limited by the leakage impedance of the exciting windings even if a core of the shunt reactor 10 is saturated and the impedance of the shunt reactor becomes zero. This means that circulating current is within the operation limit of tap change-over even if the core is saturated, thus eliminating the need for the control of the magnetic flux density of the core at low values. And the ground insulation of the windings can be lowered because a terminal of the shunt reactor is directly earthed, and layer insulation can also be reduced because other phase shunt reactor windings can also be earthed.
