Abstract: PROBLEM TO BE SOLVED: To effectively prevent drowsiness, not to lower a cushioning property and to facilitate part exchange, etc., by arranging a vibration means on an outer periphery part of a head rest by installing it on the head rest to be installed on a seat upper part of a vehicle anal vibrating this vibration means. SOLUTION: A head rest 1 to be fixed on an upper end of a driver's seat of an automobile free to connect and disconnect to and from it is furnished with a head rest part 6 and a vibration means 9 on an upper surface of an installation plate part 7a extending from a rear end surface of a support plate 7. A direct current motor 11, a pair of left and right unbalance weights 17, etc., are fixed on the vobration means 9 free to connect and disconnect to and from it. Thereafter, when a driver feels a little drowsy, he drives the direct current motor 11 by pressing a START switch, and both of the unbalance weights 17 are rotated and vibration is generated. Consequently, as the whole of the head rest 1 is vibrated, drowsiness of the driver is shaken off.  Additionally, as the direct current motor 11 is out of the head rest 1, a cushioning property is not lowered and it is possible to carry out part exchange, etc., quickly.

Title: Nitrogen absorption preventing method of molten steel
Inventor: NISHIMURA MITSUHIKO
IPC: C21C7/00
Filed: 1981-04-28
Abstract: PURPOSE:To stably obtain molten steel of an extremely low nitrogen level, by shifting the molten steel to a vessel containing dry ice, in a pure oxygen converter method. CONSTITUTION:Immediately before steel is tapped from a converter, dry ice which has been cracked roughly is thrown into a ladle, and if possible, steel is tapped after the upper part of the ladle has been covered with a steel foil, etc. In consideration of the time of throwing-in and size of the lump, the dry ice is thrown in so that it exists in the ladle until the steel is being tapped. As a result, nitrogen absorption is suppressed stably to about <=5ppm, but in case when dry ice has existed after the injection ends, its nitrogen absorption is lowered remarkably. Also, size of a lump of dry ice exerts influence on variance of the quantity of nitrogen absorption. For instance, in case when the time required for tapping steel after dry ice has been thrown in is 2min, size of the lump of about >=24mm. is desirable, and in case when the steel tapping time is 3min, size of the lump of about >=60mm. is desirable. In this case, a sufficient effect is obtained by about 0.2-0.6kg dry ice/t - molten steel.

IPC: H01J1/28
Filed: 1986-03-24
Abstract: PURPOSE:To stabilize the emission current property for a long period of time and realize a long service life, by specifying the porosity and the thickness of the covering layer of a porous W base. CONSTITUTION:A porous W base 11 is made by compressing and forming W powder of particle diameter 3-10mum into bar forms and sintered in a reducing atmosphere. The porosity of the base 11 is made at 20-40%. After it is combined with a cathode sleeve, a brazing material layer, a heater, fillers, and the like, and impregnated with an electron emission substance, the W base 11 is covered with Ir, for example, by a spattering. Then, at the final process, it is heat-treated in a high temperature vacuum to form the base metal of a W alloy layer, that is, Ir-W alloy layer 16 with the thickness of 3,000-30,000Angstrom . By increasing said porosity (p), the barium feeding amount to the surface of the cathode per unit time is made larger, and by increasing the thickness of the covering layer, the increasing speed of the W density over the surface of the cathode can be controlled. Therefore, an increase of the W density over the cathode, and a decrease of the barium feeding rate over the cathode are restricted, and the service life property can be improved.

Title: Lateral discharge continuous oscillation gas laser tube
Inventor: KASAMATSU MITSUO
IPC: H01S3/097
Filed: 1981-04-30
Abstract: PURPOSE:To suppress the generation of an arc as well as to improve the uniformity of discharge by a method wherein the cathode electrode for the subject gas laser tube is composed of a good condutive flat plate and an annular or helical heat-resisting material that was fixed on the rear-edge side of gas flow on the flat plate. CONSTITUTION:The cathode electrode is formed by fixing a helical Mo 13 on the rear edge of a copper plate 12, and the generation of a turbulent flow is reduced by forming the forward edge of the copper plate 12 into a streamline shape. As the surface of the Mo 13 works as a cathode, the discharge is uniformalized, and the generation of an arc can be suppressed. Water is passed through a hole 14 to cool the copper plate 12, and the surface of the copper plate 12 is covered by the heat-resistive insulating material such as ceramic and the like. According to this constitution, as a helical or annular Mo is used, the resistance against the flow of gas is reduced, obtaining the same results as in the case where an equivalently heavier wire is used for discharge, and a discharge is performed uniformly, thereby enabling to minimize the laser beam as well as to develope high output power.

Title: Liquid crystal display device
Inventor: TAKAHASHI KOJI
IPC: G02F1/133
Filed: 1989-03-20
Abstract: PURPOSE:To obtain high image quality without shadowing by providing an erasion period in every frame period and driving each display electrode with a voltage waveform having a high frequency component or a certain frequency component in accordance with the frequency component of a driving voltage waveform at the time of ordinary scanning in the period. CONSTITUTION:The erasion period is provided in every frame period and each display electrode is driven with the voltage waveform having the high frequency component in accordance with the frequency component of the driving voltage waveform at the time of ordinary scanning or a certain high frequency component in the period. For example, in former case, the high frequency component is not injected in the erasion period TB because the voltage waveform in the scanning period TS at a point A includes the high frequency component but the high frequency component is injected in the period TB because the voltage waveform in the period TS at a point B does not include the high frequency component. By thus driving each signal electrode, low frequency shadowing is prevented and also high frequency shadowing is not caused. Thus, a liquid crystal display device where image quality is high and the shadowing does not occur is obtained.
