Title: Source coupling type field effect transistor amplifying circuit
Inventor: IGUCHI KAZUO
IPC: H03F3/45
Filed: 1982-09-24
Abstract: PURPOSE:To improve the waveform of output voltage by connecting a non-linear element to an active load FET in parallel. CONSTITUTION:The saturation current of active load FETs TR3, TR4 is set up to a half of the saturation current of a constant-voltage regulated power supply FET TR5. In an area of which output voltage V01' is low, the voltage applied to both ends of a Zener diode D1 is high. At that time, the greater part of current is made flow into the Zener diode D1. The TR3 is a saturated area and has high load resistance to the FET TR1. In an area of which V01' is high, current is interrupted from flowing into the Zener fiode D1. Since the FET TR3 is operated in a non-saturated area, its load resistance is reduced. If gain is increased at a low input signal and an output is limited at the time of a high input signal, the output waveform is prevented from the generation of a stage.

IPC: H01L29/06
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a method for assembling a fine structure on a substrate at a low cost by putting formed blocks carrier in slurry in recessed sections formed on the substrate in a self-aligning way. SOLUTION: Slurry is formed by mixing formed gallium arsenide blocks 19 separated from silicon in an inert solution and the slurry is carried to the upper surface 53 of a silicon substrate 50. Recessed sections 55 having geometric outlines complementary to the blocks 19 are formed on the surface of the substrate 50 by etching and the slurry is circulated on the surface 53 of the substrate 50 at such a speed that the blocks 19 can get in the sections 55 and unpositioned blocks can flow continuously until a prescribed number of sections 55 is filled up with blocks 19. Since the sections 55 have trapezoidal shapes and oriented in a specific direction, the blocks 19 can tightly get in the sections 55 in a self-matching way while the blocks 19 are carried. Therefore, numerous blocks, namely, a fine structure can be formed on the substrate 50.

Title: Ink jet printer
Inventor: TACHIKAWA HARUNORI
IPC: B41J2/205
Filed: 1980-11-27
Abstract: PURPOSE:To improve the quality of recording picture elements by arranging plural nozzles each of which forms picture elements of which diameter is less than a half of the interval between scanning lines and by selectively varying the number of jetting nozzle to be operated according to the coarseness or fineness of a picture to be transmitted or received. CONSTITUTION:Two heads are installed to a carriage and a source of recording signal is connected to both heads through a change-over switch. When an original for transmission, (A), is scanned, picture signals, (B), are generated and  when these signals are recorded by a conventional head which prints picture  elements of which diameter equals the interval between scanning lines, recorded  picture elements are forced to overflow as shown in (C). In the case of this invention, the printer uses 2 nozzles which record picture elements of which diameter is about a 1/2 of the interval between scanning lines, therefore the boundary  between a white part and a black part can be clearly defined. Even if a picture is recorded at a line density of 2 times finer than that of (D), the resolution of the image is not degraded as shown in (E).

Title: Formation of projection for resistance welding
Inventor: WATANABE MASATO
IPC: B23K26/20
Filed: 1980-12-01
Abstract: PURPOSE:To form a projection of arbitrary shapes by melting the prescribed position of the surface of a welding material by means of laser light then cooling the same thereby projecting said part by the effect of surface tension. CONSTITUTION:Laser beams 5 are irradiated to the prescribed position of the surface of a welding material 4 to melt the surface of the material 4. Thence, when the irradiation of the beam 5 is stopped, the molten part diffuses its heat to the upheated part of the material 4, and is thereby quickly cooled. During this cooling, the molten part builds up at the central part by the effect of surface tension, thereby forming a projection 6. The need for press dies for forming projections is eliminated by this method. There is no generation of high internal stress, and the high weld strength after welding is expected.
