Filed: 1990-10-31
Abstract: PURPOSE:To reduce the cost and to realize a noon-adjustment device by forming a chrominance carrier signal decode circuit and a chrominance carrier signal encode circuit with simple digital signal processing circuits. CONSTITUTION:A low frequency conversion carrier signal of a 1st television system separated by a Y/C separator circuit 2 is converted into a frequency of a 2nd television system by a frequency converter 4 and inputted to an A/D converter 5. The A/D converter 5 converts the signal into a digital signal by using a reference clock and a decode circuit 7 decodes the digital signal into two color difference signals, which are written in a digital memory 8. Then the line number is properly interpolated by using a read clock and the result is read while thinning a field number and given to an encode circuit 10, in which the signal is encoded and it is converted into an analog signal by a D/A converter 11. On the other hand, the luminance signal is processed similarly. Thus, the decode circuit and the encode circuit are constituted with simple digital signal processing circuits, the cost is reduced and the non-adjustment device is realized.

Title: Ink particle electrification control system
Inventor: ONO TAIICHI
IPC: B41J2/09
Filed: 1987-11-24
Abstract: PURPOSE:To obviate the necessity for a deflecting electrode so as to reduce the distance between a nozzle and a drum, thereby simplifying an electrode unit by forming two holes in a nozzle and providing an electrifying electrode for synchronizing ink particles injected through these two holes as well as electrifying the two ink particles so injected so as to allow them to be the same poles. CONSTITUTION:Two holes (orifices) are formed in a nozzle 10 at positions equally away from the center thereof in the same conditions. Ink particles pressurized by means of the nozzle 10 so as to be synchronized are deformed to be constricted by means of a piezo-vibrator and thereby become granular particles. A pulse voltage of about 500V is impressed to these granular particles from an electrification control circuit 20, and ink particles are thereby electrified with a negative electric charge by virtue of static induction. The ink particles are caused to undergo a phase control at their broken points by utilizing an electricity control circuit, and electric signals are caused to synchronize with ink particles, whereby every other particles are fed as a setting signal from an electrifying electrode 12. As a result of this, the two ink particles are caused to deflect by the action of interparticle repulsion so as to be set on an exclusive coated paper on a drum 16 after passing through a garter 14.

Title: Manufacture of semiconductor device
Inventor: OKA KENJI
IPC: H01L23/28
Filed: 1988-11-22
Abstract: PURPOSE:To perform powerful printing readily by incorporating a resin sealing step, a step for blowing fine powder having high hardness to at least part of the surface of the resin after the resin sealing step and a step for performing printing on the surface of the resin. CONSTITUTION:After resin sealing, fine powder having high hardness, e.g., fine alumina powder 3, is blown, and a surface is made coarse. As the fine alumina powder, roughness of #600-#1,200 is suitable. Thereafter, printing is performed on the surface. At this time, the surface is not cleaned with solvent and the like as a pre-treatment, but it is recommended to blow out the fine alumina powder with highly compressed air. This is because the new surface is not contaminated with the solvent. That is, the surface of resin is scraped by blowing the fine powder having the high hardness, and the new coarse surface is obtained. Thus the printing strength on the surface can be remarkably increased.

When a cutting of the packaging material by a cutter blade has been completed, the suction port is pulled by the cylinder, and the end surface of the web is removed. At this time, for the positioning of the cutter blade to the end surface of the web, a detection of the position is conducted by the presence of a reflected signal from the web by a sensor 6; by a combination of the signal output of the sensor 6, the output from AND circuit stops; the operation of a motor 9 is stopped; the position of the cutter blade is set automatically at a most appropriate position. Therefore, the adjusting time can be shortened without a worker.

Title: Outdoor unit for air conditioner
Inventor: KIDA TAKUMI
IPC: F24F5/00
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To suppress the collapse of a vortex in the rear edge part of the outer peripheral part of the vane of the impeller of a blower, prevent the increase of the pressure pulsation of all the vanes and suppress the increase of noise of the blower in the outdoor unit of an air conditioner provided with the blower in the side of an upper face panel by providing an inlet port on at least one side face panel of a box body. SOLUTION: A substantially cylindrical ring 14 having an inside diameter d2 larger than the minimum inside diameter d1 of an orifice 13 is attached to the discharge side 13b of the orifice 13. The difference s between the minimum inside diameter d1 of the orifice 13 and the inside diameter d2 of the ring is more increased in a side face panel 2b side provided with an inlet port 3 than in a side face panel 2b' side provided with no inlet port 3. Thus, a vortex U1 does not abruptly collapse just after the rear edge 12e of the negative pressure side 12b2 of the outer peripheral part 12b of a vane 12 and moves to the discharge side 13b of the orifice 13. Accordingly, pressure fluctuation just after the rear edge 12e of the outer peripheral part 12b of the vane 12 is prevented so that the increase of pressure pulsation of the whole vane 12 is suppressed.

Filed: 1985-12-27
Abstract: PURPOSE:To effectively compensate various aberrations by providing a distributed index negative lens which is a convex lens, but has negative power on the whole where negative power is required in terms of the power arrangement of a lens system. CONSTITUTION:This optical system consists of the 1st positive lens which has a large-curvature convex surface on an object side, the 2nd positive lens which has a large-curvature convex surface on the object side, and the 3rd negative lens which has a large-curvature concave surface on an image side. Further, the optical system has a front group which has positive refracting power and a rear group so that a large air gap is left between them. The rear group consists of the 5th negative lens and the 6th positive lens.In this case,the 5th negative lens is a convex lens, but has negative power on the whole because its medium has a refractive index distribution which increases in refractive index from the optical axis to the outer peripheral part at right angles to the optical axis. Thus, surface shapes and the distributed index lens are selected to reduce the spherical aberration, coma aberration, distortion, etc.
