Title: Method and apparatus for generating
Inventor: IAN AREKISANDAA SHIYANKUSU
IPC: G02F1/13
Filed: 1989-10-06
Abstract: PURPOSE: To improve contrast with noise caused by light from a light source by constituting a means for modulating light so that it can act between a 1st mode in which it is translucent and a 2nd mode in which it is transparent. CONSTITUTION: The light modulating means 10 has a demarcated surface and acts between the 1st mode in which it is translucent and the 2nd mode in which it is transparent, and its action is performed in synchronism with the change of light intensity. In such a case, the means 10 in the 1st mode forms a translucent screen where a video is reflected to be directly observed by an observer 17 on the same side as the projector 3 of the means 10. In the 2nd mode, the means 10 is transparent, so that there hardly exists the light diffusively reflected to the observer 17 from a plane P1 . The influence of peripheral light made incident on the demarcated surface of the means 10 is reduced and the contrast is improved.

Title: Production of square steel pipe
Inventor: KAJI EIKICHI
IPC: B21C37/15
Filed: 1984-12-10
Abstract: PURPOSE:To produce efficiently and continuously a square steel pipe by subjecting successively a steel strip having a prescribed width to top side corner and bottom side corner bending by means of longitudinal die plates synchronized with the feed speed during bend pressing and subjecting the same to welding, bead removing, leveling and standard size cutting after square forming with rolls. CONSTITUTION:The steel strip 1 which is un-coiled 2 is leveled by a leveler 4 and is welded at the front and rear ends by a welder 5. The strip is then cut to the prescribed width by an edge preparing machine 9 and is fed into a top side corner bending press 11 by constant speed feed rolls 10. The top side of the steel strip is successively bent to about 80 deg. in the press 11 by the longitudinal upper die 20 and lower die 30 moving synchronously at the feed speed of the strip 1 by cylinders 34, 39 during pressing. The steel strip enters a bottom side corner bending press 13 after top side corner forming 12 and is bent about 80 deg. at the bottom side 2 bend part by the longitudinal upper die 48 and lower die 49 operating similarly. The strip is thereafter subjected to roll 90 deg. forming 14, butt welding 15, 16, bead removing 18, shaping 19, leveling 20 and standard size cutting 21, by which the steel strip is made into the prescribed square steel pipe P. The efficient and continuous production of the square steel pipe P to the good shape is thus made possible.

Title: Thinned seamless can
Inventor: GOTO HIROAKI
IPC: B21D51/18
Filed: 1994-10-25
Abstract: PURPOSE: To increase the anticorrosition property and external appearance, by providing an ultraviolet ray setting coating layer mixed with titanium oxide with a specified thickness on the external face film layer at the side wall of a metallic material and setting the total amount of titanium oxide per unit area of the side wall of external face at least in a specified value. CONSTITUTION: In a thinned seamless can 1, the metallic base material 11 is coated with a thermoplastic film at both inside and outside and an ultraviolet ray setting coating layer 16 mixed with titanium oxide having 3-20 micron millimeter in thickness is applied on the external face side film layer of the side wall 3. And the total amount of titanium oxide per unit area of the external face side wall is at least 0.5mg/cm<2> . When the thickness of ultraviolet ray setting coating layer 16 mixed with titanium oxide is finer than 3μm, a sufficient whiteness degree cant not be obtained and also the hiding power is not enough. On the other hand, when the thickness is larger than 20μm, the coating layer can not follow at the neck-in process and hence, the coating layer is broken.  Since the coating layer has been hardened by ultraviolet ray, it is lustrous and excellent in score-resistance and hence, the external appearance characteristics are increased.

Title: Semiconductor device
Inventor: MURO HIDEO
IPC: H01L29/73
Filed: 1984-12-12
Abstract: PURPOSE:To prevent the thermal breakdown of power transistor elements by a method wherein npn transistors and MOS transistors are formed on the same substrate, and the base of the former is thermally coupled with the channel of the latter. CONSTITUTION:A plurality of npn transistor parts 21 and depletion type MOS transistor parts 22 are connected. When voltage is impressed on a base terminal 17b, the current of the MOS transistor part 22 is supplied to the base of the npn transistor part 21, resulting in an ON-state. The base terminal 17b is driven on constant current, and the MOS transistor part 22 is operated in such a region that a parasitic pnp transistor does not set in action. When local high- temperature parts generate by the flow of large current to any of the transistor parts 21 in current concentration, the heat is transmitted to a channel region 20 through the base layer 13, and the temperature of that place rises. Because of the decrease in mu on the increase in temperature, the drain current reduces, and the base current of the transistor part 22 reduces; accordingly, a feedback that reduces the collector current sets in action.

Abstract: PURPOSE:To obtain a lighting head suitable for a flame monitor apparatus by providing optical fiber receiving parts allowed to be formed and positioned at different angles and the optical fiber communication part communicated with said receiving parts to the leading end part of a main body. CONSTITUTION:In the lighting head of a flame monitor apparatus using an optical fiber, grooves 10a, 10b, 10c for receiving the leading end parts of optical fibers are formed at different mount angles.
