Title: Ink jet recording method
Inventor: ASAI AKIRA
IPC: B41J2/14
Filed: 1988-06-20
Abstract: PURPOSE:To make a discharged ink droplet very small and thereby to enable the attainment of high-density recording by minute picture elements, by making ink discharged by using a pressure obtained when a bubble contracts after it expands to the maximum volume, and then expands again. CONSTITUTION:When an electric pulse signal is inputted, an electrothermal transducing body 1 is heated and thereby a bubble 3 is generated in an ink liquid 2 and expands to the maximum volume. On the occasion, however, the discharge of the ink liquid 2 does not occur by the reason that fluidics impedance is large. Subsequently the bubble 3 is cooled down by the temperature of the surrounding ink liquid 2 and contracts rapidly, and a meniscus in a discharge port 5 retrogresses with this contraction. As the bubble 3 contracts rapidly, condensation of gas in the bubble lags behind. Consequently the pressure of the gas in the bubble turns high sharply, the bubble 3 expands again while generating a shock wave, and a projection is formed in the meniscus in the discharge port 5. The projection turns to be a very small ink droplet 6 and flies, and it sticks on a recording medium and becomes a picture element forming a character or an image.

Filed: 1981-09-22
Abstract: PURPOSE:To prevent slack of tape with a simple construction, by releasing the block of rotation of a reel with a brake member provided in a cassette via a positioning ball, when loading the cassette in the playing state. CONSTITUTION:In response to positioning holes 29, 30 inserting positioning balls 26, 27 of a cassette, brake members 31, 32 blocking the free rotation of a pair of reels 7, 8 are provided in the cassette. In loading the cassette to the playing state with the brake members 31, 32, the members are activeted via the said balls 26, 27 to release the blocking of rotation of the reels 7, 8. For example, the members 31, 32 are provided as shown in Figure for a long time video recording/reproduction VTR tape cassette. In loading the cassete on a cassette stand 28, the head of the balls 26, 27 pushes up other ends 24, 25 of the brake members 31, 32 and detaches ends 22, 23 from gears 20, 21 to release the latch of the reels 7 and 8.

Title: Semiconductor device
Inventor: KONDO TOSHIHIKO
IPC: H01L21/8246
Filed: 1990-06-08
Abstract: PURPOSE:To aim at achieving higher integration, higher speed operation, and shortening of delivery time by the means of constitution of an opening formed on the prescribed part of the second region (the 2nd conductive type) of a polycrystalline silicon layer and the second conductive layer with AL main component, which is formed over the opening. CONSTITUTION:With a contact opening as a base of one unit cell, electrical sensing contributes to the decision of whether opening of a contact is necessary or not, or contributes to the confirmation of whether a wiring layer 108 and a conductive layer 103 make continuity or not. As a result, a cell becomes an exclusive read memory by judging the data. Even if the conductor layer 104 and the wiring layer 108 are simply connected with each other at an opening 107, short-circuit occurs between cells in the cell part which is formed in matrix condition. To avoid this, a polycrystalline silicon layer is installed beneath of the opening, and P-N junction is made by forming N-type impurity layer 104 and P-type impurity layer 105. In this way, short circuit is avoided due to this operation of rectification. Therefore, a semiconductor can make performance due to electrical continuity of the conductive layer 13 and the wiring layer 108, and higher speed can be obtained due to its lower resistance than that of ON resistance of a transistor.

Abstract: PROBLEM TO BE SOLVED: To produce a coated Al-Zn alloy plated steel sheet free from the generation of edge creep in the cut part by applying hot dip plating of an Al-Zn alloy of specified quality to a steel sheet, thereafter executing uniformizing treatment and applying coating to the surface. SOLUTION: A steel sheet is immersed in a hot dip plating bath of an Al-Zn alloy contg. 20 to 75% Al, and the surface of the steel sheet is plated with the Al-Zn alloy. Next, it is charged into a annealing furnace and is subjected to uniformizing treatment of executing cooling after heating to form the plated layer into the one in which β phases (the phases in which Al enters into solid solution in Zn) are finely dispersed into the matrix of α phases (the phases in which Zn enters into solid solution in Al). Successively, the plated steel sheet is subjected to deqreasing, pickling, chromating treatment and phosphating treatment to form a chemically converted layer, and after that it is coated by a roll coating method. As for the coating, it is coated with a primer coating material, is baked and is thereafter coated with a finish coating material.  This coated Al-Zn base alloy plated steel sheet is excellent in edge creep resistance in the cut part.

Filed: 1983-08-19
Abstract: PURPOSE:To obtain a recording picture with high resolution by splitting the luminous flux from an object image into two by a half mirror, arraging a solid- state image pickup element to each image forming position of each luminous flux divided into two, shifting a scanning pitch in the sub-scanning direction at each solid-state image pickup element by a half pitch and combining alternately the outputs of the solid-state image pickup element in a prescribed order so as to record the picture. CONSTITUTION:When picture signals S1, S2 are picture signals representing the object images shifted by a half of the interval of two adjacent scanning lines, the recording synthesis picture signal is synthesized by using the picture signals S1, S2 at each alternate scanning line as the (n+1')-th line scanning line information of the pucture signal S1 at first, then the (n+1'')-th scanning line information of the picture signal S2, the 1st scanning line information of the picture signal S1 again and then the 1''-th scanning line information of the picture signal S2,-. Since the frequency of the synthesized picture signal S obtained from the result is a frequency twice that of the picture signals S1 and S2, the resolution of the screen is doubled.

Filed: 1978-12-05
Abstract: PURPOSE: To make possible visual monitoring by detecting the exposure condition with a beam irradiated on a photosensitive plate on the same condition as imposed thereon in place of a semiconductor wafer when a impurity element is injected into the semiconductor wafer by electrostatically accelerating thereof through ionization.  
     CONSTITUTION: A specified amount of ion is injected into a wafer by irradiating an ion beam through a vertical and horizontal deflection plates. In this process, prior to the injection, a beam is irradiated to a photosensitive plate 4 on the same con- dition as imposed on the wafer supported by a wafer holder 5 in the case of cassette type or by a platen 6 in the case of wayflow type. The photosensitive plate 4 adopts an X-ray film and a photographic printing paper. After a scanning on the entire surface thereof, the plate is developed to detect the exposure condition. Depending on the beam irradiation time, the scanning is coarse when it is short while dense while it is long. Therefore, observation of the scanning will permit easy discrimination of treatment conditions including the amount of irradiation.

Abstract: PURPOSE:To simultaneously detect the position deviation of a probe at the time of characteristics test using the probe, reduce the cost of IC test, and improve reliability, by forming a metal film pattern insulated from an electrode pad around the electrode pad, and connecting the metal film patterns in each chip resin by using a common wiring. CONSTITUTION:Around an electrode pad 2 on a semiconductor wafer 1, a metal film pattern 5 insulated from the electrode pad 2 is formed. All of the metal film patterns 5 in a chip region are connected by using a common wiring 5a for each chip region. For example, the above pattern is constituted by an Al film whose one side is 100mum, and connected with an inner circuit. Around the electrode pad 2, an Al film pattern 5 of 20mum width is formed, and connected with an electrode pad for grounding by a common wiring 5a for each chip. When the tip part 4 of the probe for testing comes into contact with the Al film pattern 5 positioned at the end-portion of the electrode pad 2 as the result of position deviation as shown in figure, the probe also turns to a grounded state, so that the position deviation can be immediately detected.
