Title: Manufacturing method for semiconductor device
Inventor: ITOU MORITOMO
IPC: H01L29/417
Filed: 1979-05-25
Abstract: PURPOSE:To lessen the bad influence given to a gate electrode due to the concentration of an electric field generated in a drain region and also to give an improvement in the withstand voltage of an element by having a heat oxidation after giving an etching in such a way that the size of a gate oxidation film will be smaller than that width of an electrode. CONSTITUTION:An Si oxidation film 12, a polycrystalline film 13 and a photo resist film 15 are formed successively on a P-type Si substrate 11. A polycrystalline silicon gate electrode 16 is formed using the formed photo resist film 15 as a mask, and then after a gate oxidation film 17 is formed, impurity regions 18' 19' are formed by an ion injection, and then the photo resist film 15 is removed. When an Si oxidation film is formed by heating a substrte, the injected impurities are activated, and a source region and a drain region 19 are formed. At this time, a heat oxidation film 20 pushes up the end section of a polycrystalline silicon gate electrode 16 and the said regions are formed with a limited part having a heavier thickness.

Title: Rotating quantity detector of selsyn motor
Inventor: TANABE YASUHIRO
IPC: G08C19/38
Filed: 1978-05-29
Abstract: PURPOSE: To detect rotating quantity with a simple constitution by driving relays by the alternating voltages produced in the secondary windings of a selsyn motor and counting the outputs of the relays with a counting means.  
     CONSTITUTION: Relays X 1 , X 2  are driven by the alternating voltages produced in the secondary windings S 1 , S 2 , S 3  of a selsyn motor and the outputs of the relays X 1 , X 2  are counted with a counting means, whereby rotating quantity may be detected. The secondary windings S 1 , S 2 , S 3  are of 3 phases and therefore if relays are connected between the mutually different 2 pairs of lines, these two relays are driven at different points and therefore the rotating direction may be detected as well by monitoring these output points. In addition, if the two relays are driven by different voltages, the rotating direction may be accurately detected even if rotating speeds fluctuate.

Title: Scanning system converting device from sequential image scanning to skipped scanning
Inventor: ICHIHARA HITOSHI
IPC: H04N7/01
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To enable scanning system conversion in simple circuit configuration by using a frequency in the specified relation between the number of read clocks and the number of write clocks. SOLUTION: Memories A and B respectively have write terminals, read clock terminals, address counter reset terminals, OE terminals and input/output terminals and signals are applied from a timing circuit 102 to the respective terminals and converted. The timing circuit 102 works a horizontal synchronizing signal 4 of VGA(video graphics array) while using a counter with which a logical output is inverted for 530 outputs, applies a switching signal 3 to a switching means 2 and selects data to be applied to the memories. When connecting a terminal (b) of the switching means 2 to a connector, a video signal is delayed just for one horizontal scanning period by a 1H delay circuit 1 and applied to the memories A and B. In such simple configuration, the scanning system conversion from the video signal of VGA to the video signal of NTSC can be performed in simple circuit configuration.
