Title: Semiconductor device and its manufacture
Inventor: MIYAMOTO SHOICHI
IPC: H01L27/11
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To ensure a large channel region in a small occupied area and to obtain a large current by a method, wherein a plurality of branches are formed in a channel and a gate and branch channels are formed in such a way that they are surrounded by branch gates, so as to cross three-dimensionally. SOLUTION: A bottom-part branch gate 8a is formed on the surface of an insulating film 2, and a plurality of branch gates 8b to 8e which are branched from the bottom-part branch gate 8a are arranged on the upper layer of the bottom-part branch gate 8a. Thereby, the branch gates 8a to 8e form through- holes between themselves. Branch channels 6a to 6d are united on sides, on the other side, through the through-holes from sides, on the one side, of the branch gates 8a to 8e. In addition, a gate oxide film 7 is formed between the branch gates 8a to 8e and the branch channels 6a to 6d, and the channels 6 are connected to a source/drain region on the both sides of the through-holes in the gates 8.  By making it this structure, a semiconductor device can obtain a channel region of about four times or higher in the same occupied area, as compared with that of a single gate-type semiconductor device.

Title: Television screen printer
Inventor: HIRASHIMA MASAYOSHI
IPC: G06F3/153
Filed: 1979-12-12
Abstract: PURPOSE:To perform screen print of excellent picture quality with gradations by digitizing a picture on a TV screen, by varying the width of a print pulse in proportion to the signal and by forming coloring density corresponding to the width. CONSTITUTION:Since a picture on the TV screen obtained by detecting circuit 3 is a motion picture, one field is extracted by analog field memory 4 and stored. In this case, input switch 6 is changed over from A to C and the output of memory 4 is inputted to interface circuit 7. Circuit 7 is provided with two comparison levels and while black-level and white-level voltages are generated, A/D conversion is performed to generate a print pulse of pulse width that corresponds to an analog signal. This pulse is supplied to the hand of printer 13. When this head is a thermal head, the color changing width of heat-sensitive paper varies with power feed time, i.e. the pulse width of a driving signal, so that the density will vary apparently. Through the A/D conversion of circuit 7, pulses that correspond to halftone gray as well as black and white can be obtained, so that the quality of a print screen will be improved.

Filed: 1982-09-17
Abstract: PURPOSE:To effectively suppress the propagation of microbes without the formation of corrosion, etc. in piping, in a piping system for circulatorily reusing water used for cooling arrangements, by moving up and down the pH value of water within a specified range at every arbitrary period of time. CONSTITUTION:By raising a pH value from the condition that the number of living microbes in 1ml circulating water represents a value 5 above 9, as shown in 7, the number of living microbes is rapidly reduced as shown in A'', B'' after the lapse of a predetermined time, to exhibit the effect of pasteurization. However, when another predetermined time B'', C'' has passed, microbes resistance to a high pH are propagated so that the number of living microves begings to increase gradually and then exponentially as shown in D'', E''. By lowering the pH value of water below 4 as shown in 8 at an optional value 11 to act as the point of controlling the number of living microbes, the number of living microbes is rapidly reduced again. Thus, by periodically alternately changing the pH value of water, the stable effect of pasteurization can be obtained over a long time.

Abstract: PURPOSE:To correct positional deviation caused by mechanism distortion and to make cross mark projection positions coincident for right and left pointers by calculating the feeding quantity of an arm module required for moving a mark from data to a position to be projected and moving the pointers to the desired positions. CONSTITUTION:The data, which are measured and stored in a muPU 10, are concerning B and D points. On a projecting surface in the B point of 20mm, the cross mark position is 19mm and on a projecting surface in the D point of 40mm, the cross mark position is 43mm. When the pointers are moved from an A point to a C point, moving quantity (a) is calculated at first by the position information of an origin and B point stored before and behind the position, which is the purpose of the move, and next, moving quantity (b) is calculated by the position information of the B and D points. For moving quantity (p) of an arm module 7L required for moving the pointers from the A point to the C point, the condition of (p)=(a)+(b)=18.64 is established. Then, when the number of pulsed to be sent to a left side pointer moving motor 5L for moving the arm module 7L by 1mm is defined as alpha, it is enough to send the 18.64alpha of the pulses. Thus, the cross mark is projected on a reagent enough exactly for a practical use.
