Title: Liquid jet recording
Inventor: SEKIYA TAKURO
IPC: B41J2/05
Filed: 1988-03-16
Abstract: PURPOSE:To allow gradation recording to be performed and printing speed to be set at the same level as when gradation recording is not performed in a normal operation mode by entering an independent energy-level signal in at least two independent areas and permitting a single bubble to generate by a combination of said signals and its size to change. CONSTITUTION:A heat-generating element section is, for instance, divided in two elements 19a, 19b, and these are allowed to drive independently by means of their respective control electrodes. Signals E1, E2 are so timed as to enter the two heat-generating elements 19a, 19b almost simultaneously to generate a single bubble. It is possible to generate bubbles of different sizes by combining the values of E1 and E2. Accordingly, the size of ink droplets to be discharged changes and the diameter of pixels can be changed to enable gradation recording. Both heat-generating elements are caused to drive concurrently, so that bubble production time can be shortened and discharge response speed be increased. At the same time, the gradation recording can be achieved at almost the same speed as the non-gradation recording.

Abstract: PURPOSE:To enable to sufficiently increase the ratio of film thicknesses of a gate oxide film and an interlayer oxide film in a double layer polycrystalline Si device by enabling to control the film thickness of the gate oxide film and that of the interlayer oxide film respectively in an independent manner. CONSTITUTION:A field oxide film 2 and a first gate oxide film 3 are formed on a P type Si substrate 1, and a polycrystalline Si film 4 is formed thereon. Thereafter, the film 4 is doped with phosphorus. Then, the film 4 is etched after patterning a photo resist 10.

After removing the resist 10, the interlayer oxide film 5 is formed by oxidizing the film 4. In this case, the film thickness of the thermal oxide film 3' on the layer 9 is constant, which layer 9 then disappears. After removing the film 3', the second gate oxide film 6 is formed on the exposed surface of the substrate 1 by thermal oxidation. A second polycrystalline Si film 7 is formed on the films 6, 5 and 2, which Si film is then doped with phosphorus. Thereby, the ratio of the film thicknesses of the films 6 and 5 can be sufficiently increased.

Abstract: PURPOSE:To obtain optimal lap printings by varying the bias amount of lapping letters according to sizes set by size-designating signals. CONSTITUTION:The sizes and biassing directions of lapping letters to be printed according to signals for designating size and lap printings are set up. When a letter signal is sent out, corresponding pattern data are taken in by the first controller from a pattern memory, and a paper feeder, a carriage driver, and a printer driver are controlled according to the set sizes. A recording paper and a printer are relatively moved and given letters of set sizes are printed on the recording paper. The second controller, then, controls the paper feeder and the carriage driver in such a way that the starting position of printing for the next letters after the completion of the letters is biased with a biassing amount set according to the set size. Since the first controller again controls each device for printing the same letters from the starting position of printing the next letters, the lapping letters to be formed have optimal biassing amounts based on the sizes.

Filed: 1988-03-18
Abstract: PURPOSE:To enable sure handling even at the time of a small carrying-load quantity in series conveyors by selecting one conveyor on the upper course side as a carrying-load detecting belt conveyor and detecting the existence of a carrying load, and carrying out the starting/stoppage of the conveyors from the upper course side in order at a defined timing in accordance with the existence. CONSTITUTION:With belt conveyors 1, 2 being previously operated, as a raw material is fed onto the belt conveyor 1 from an unloader 6 and loaded on the belt conveyor 2, a belt wear 10 outputs an output value proportional to a conveying quantity to a judging device 11. Thus, as the carrying load is detected, a control device 12 starts a third and following conveyors in order prior to the arrival of the carrying load at each conveyor to make the conveyors in a conveying condition. On the contrary, when the carrying load runs out, the belt conveyors are stopped from the third belt conveyor in order each being delayed by the time at which the carrying load becomes zero based on the signal of the judging device 11. By this structure, the starting/stoppage can be carried out surely and efficiently even when a carrying-load quantity is small.
