Abstract: PURPOSE:To ensure highly efficient implantation of ions into a small cell area by a method wherein a floating gate electrode is built in an ion-implanted layer of the second conductivity type, a selective gate electrode is formed in a second gate insulating film, and a drain region and source region of the second conductivity type are formed on the surface of semiconductor to sandwich the floating gate electrode and selective gate electrode. CONSTITUTION:An n type impurity is implanted by the ion implantation method into the surface of a p type substrate for the formation of an n type inversion region 2. A floating gate electrode 4 is built in the n type inversion region 2 through the intermediary of a first gate insulating film 3. With the floating gate electrode 4 acting as a portion of the master, a p type impurity is implanted by the ion implantation method into a portion of the n type inversion region 2, for the formation of a p type region 5. Next, a second gate insulating film 7 is formed on the p type region 5. An insulating film 6 is next formed on the top and sides of the floating gate electrode 4. A process follows wherein a selective gate electrode 8 is formed with an end thereof in contact with the insulating film 6 situated on the floating gate electrode 4. A drain region 9 and source region 10 are formed by implanting an n type impurity so that they may sandwich the floating gate electrode 4 and selective gate electrode 8.

IPC: G03F1/32
Filed: 1995-04-21
Abstract: PURPOSE: To surely shield the peripheral part of an effective region of a halftone phase shift mask from light by a simple method without using a complicated light-shielding band which is conventionally used. CONSTITUTION: A translucent phase shift film 2a of a desired pattern and a light-shielding film 11b of almost the same pattern are formed on a transparent substrate 1 by etching. Substrate 1 consists of the effective region 8 of an area (a×b) where the desired pattern is formed and the peripheral part 9 surrounding the effective region. The light-shielding film 11b is deposited on both of the phase shift film 2a in the peripheral part 9 and the phase shift film 2a in the effective region 8. However, the edge of the phase shift film 2a is formed to project in the horizontal direction by length Z from the edge of the light- shielding film 11b. With this projected part, the phase of exposure light is inverted between the light-shielding part and the light-transmitting part which interpose the projected part between them so that these parts can be clearly separated from each other.

Abstract: PURPOSE: To distinguish the degradability by adding pulse to a counter and then to a stepped wave generator, and applying this stepped wave to a C-MOS integrated circuit and stopping the pulse when an abnormal electric current has exceeded beyond a prearranged value.  
     CONSTITUTION: The pulse is added to the counter 2 from a pulse generator 1 and then is input to the step pulse generator 9. The step pulse from the generator 9 is applied to the C-MOS integrated circuit 12 and its abnormal electric current is converted to voltage by means of resistor 13. This voltage is compared with reference voltage 14 with the assistance of a comparator 15. When voltage of the resistor 13 has exceeded the reference voltage 14, it is held on a voltage-holding circuit 16 and power supply voltage for the C-MOS integrated circuit is reduced to nothing by means of a switching part 17. At the same time, the pulse generator 1 is stopped. The quality of the C-MOS integrated circuit is determined, depending on the details of the counter 2.

Title: Image input optical system
Inventor: NAGATA SHINICHI
IPC: H04N1/04
Filed: 1995-05-19
Abstract: PURPOSE: To obtain the image input optical system with excellent color reproducibility. CONSTITUTION: Light from a white light source section 61 is emitted to a slit 62. The light passing through the slit 62 is projected onto a color original 3 via a cylindrical lens 63 and a prism 64. An image forming optical system 81 forms an image of the color original 3 onto an image sensor 82 with nonmagnification. The slit 62 and each of line light receiving elements LB, LG, LR are conjugated independently in each color. Thus, only a spectral light corresponding to each color individually reaches each line light receiving element provided on the image sensor 82. Thus, even when the spectral characteristics of the image sensor 82 itself is insufficient, the image of the color only is received accurately by each color and then the color reproducibility of the image is enhanced.

Title: Television camera
Inventor: TOMIZUKA HIDEKI
IPC: H04N5/243
Filed: 1994-06-03
Abstract: PURPOSE:To obtain a natural video signal without shock due to gain switching even in the on-air state by changing continuously a gain of a video signal in a prescribed time constant. CONSTITUTION:When a gain is changed, a discrete gain control signal 2a corresponding to,e.g. 0dB, +9dB, +18dB respectively is fed to a gain control signal arithmetic processing circuit 3. The arithmetic circuit 3 generates a gain control signal 3a changing continuously up to a supplied gain control value from a current gain control value based on the supplied discrete gain control values by the software processing and outputs the gain control signal 3a to a gain variable circuit 1. Thus, since the gain of the gain variable circuit 1 is changed continuously at a prescribed time constant at gain switching, a natural video signal without shock at gain switching is obtained. Then a video input 1a is amplified by the gain of the gain variable circuit 1 changed continuously and outputted as an output signal 1b.

Title: Controlling method for suction and exhaust valve lift in tappet valve controller of internal combustion engine
Inventor: MATSUMOTO YASUO
IPC: F01L13/00
Filed: 1986-05-29
Abstract: PURPOSE:To decrease the beat sound in the shift of cam by controlling the rotation speed of a multi stage cam for varying the inclination of a lever when being shifted from the cam face of a small lifting quantity side to that of a large lifting quantity side in a tappet valve device for supporting the back face of a rocker arm float ingly moved by the lever having a cam face. CONSTITUTION:The back face of the rocker arm 13 abutted at its end to a cam 11 and at the other end to a valve 12 and floatingly moved is supported by the lever 15 abutting at its end to a multi stage control cam 20 and at the other end to the back face of the rocker arm. The rotation of the control cam 20 varies the inclination of the lever 15 for changing the timing to open and close a suction and exhaust valve 12 due to the change of the fulcrum of the rocker arm. The rotation speed of the cam must be controlled so as to become slow in the former half and rapid in the latter half when the control cam 20 is shifted from the cam face on the small lifting quantity side to that on the large lifting quantity side. Since the rotation speed in the former half is slow, the rotation quantity of the lift control cam when releaved from the reaction force after completion of valve lifting can be regulated in smaller quantity.
