Title: Mask rom device
Inventor: OOGISHI TSUTOMU
IPC: G11C11/00
Filed: 1981-08-05
Abstract: PURPOSE:To make an ROM system complete in a short time with low cost, by adding an EPROM only storing a different content, when a part of a content of a mask ROM is different and the most parts of the contents are the same. CONSTITUTION:Most parts 12 except a part 13 of a mask ROM 11 are written with information common to each user. Each address of an EPROM 14 having the same storage capacity as the part 13 is the same as that of the part 13. The most parts 12 of the mask ROM 11 are read out in response to the address information from an address buffer 15 and outputted to a data bus line 18 via an opened gate circuit 17. On the other hand, address information corresponding to the part 13 is obtained from the address buffer 15, then an address discriminating circuit 16 outputs a discrimination signal, closes the gate circuit 17, inhibits the readout from the mask ROM 11 and the content of the EPROM 14 accessed according to the address information in this case is read out to the data bus line 18.

Title: Offset gate type mos field effect transistor
Inventor: NAMIKI MASAYUKI
IPC: H01L21/822
Filed: 1979-09-26
Abstract: PURPOSE:To obtain a channel current having an abrupt rise for a prescribed voltage between a source and a drain in an MOS field effect transistor by forming a low impurity region between the source and the drain and forming a gate electrode through an insulating film. CONSTITUTION:A gate electrode 6 is formed on a part of an SiO2 film 5 on a low impurity region 1a. Since a part of the electrode 6 is not superimposed with the region 1a, when a voltage is applied between the drain 3 and source 4, a current Ic will not immediately flow therebetween, but when a voltage of certain amount is applied thereto, a channel 2 is created at a part of the region 1a. However, the part 1b of the region 1a is not depleted, and no current will flow. When the voltage is raised to VSW, the entire region is depleted, and a current Ic is resultantly abruptly flowed. The portion DELTAL becoming no channel is expressed in size by the product of the threshold voltage VSW and the expanding width omega of the depletion layer in the layer 1a, and the DELTAL and the VSW are determined by the density of the substrate.

Title: Length measuring method using electron beam
Inventor: SHIMADA HIROSHI
IPC: G01B15/00
Filed: 1989-05-17
Abstract: PURPOSE:To make it possible to perform automatic positioning in a short time by displaying the image of a sample including a pattern whose length is measured, and performing correlation processing for the specified region to be noted in the image and the image after the movement of a stage. CONSTITUTION:A position on which an electron beam EB is projected is changed through a computer 6, a scanning circuit 5 and a deflector 4. The beam EB is converged by convergent lenses 1 and 2 on a sample 3 whose length is measured on which patterns are formed. Reflected electrons which are generated from the sample 3 are detected by a reflected electron detector 7. The signal is amplified in an amplifier 8 and converted into the digital signal in an A/D converter 9. Thereafter, the signal is supplied into a frame memory 10 through the computer 6. Then, the image signal stored in the memory 10 is read out and supplied into a cathode ray tube 11. Thus the image of the reflected electrons from the sample is displayed.

Title: Quantitizing circuit
Inventor: NARA KIYOYOSHI
IPC: G06K9/38
Filed: 1979-09-26
Abstract: PURPOSE: To obtain different quantitizing information and easily discriminate a character, by changing the threshold which is used in case a photoelectric conversion signal obtained by scanning a character is quantitized, whenever 1 frame of character is scanned.  
     CONSTITUTION: The surface array 2 consisting of photoelectric conversion elements of mxn pieces in the photoelectric conversion part 1 is driven for scanning in order in the line direction and also in the row direction, and a photoelectric conversion signal is sent from the out-put register 4 in order by a line each to the comparator  12 for quantitization under the control of the shift register 3. The shift register 3  sends a frame end pulse to the J-K flip flop 8 whenever scanning of 1 frame consisting of mxn bit is finished. The J-K flip flop 8 changes the threshold supplied to the  comparator 12 to large and small in order whenever scanning of 1 frame is finished.  As a result of the foregoing, both the somewhat thick pattern and the somewhat thin pattern are obtained, and proper discrimination can be performed by selecting one pattern depending on the pattern status.

Title: Handle lock
Inventor: MINEMURA TOSHIO
IPC: E05B13/08
Filed: 1993-05-26
Abstract: PURPOSE:To prevent a gate bar from locking in an oblique state by arrangedly providing gate bar members being protruded or evacuated through the rotation of a cam symmetrically on both sides, and protruding the gate bars about symmetrically in two directions. CONSTITUTION:A handle 13 and an inner case bolt 12 are unitedly rotated to actuate a lock mechanism by a bolt 12d for opening a door 20. In the case of locking the door 20, when a key is drawn out of a lock 15, and the handle 13 is returned to a fixed position and then pushed into the handle receiving section 11d of a handle case 11, gate bar members 17 move back along a slotted hole 12c, and protrude outward at an engaging notch 12b to engage both the engaging notch 12b of the inner case bolt 12 and the recess 18 of the handle case 11 for completing a locking process. In the case where the gate bar members 17 are arranged provided so as to be symmetrical at 180 degrees centering around an axial center, and the handle case 11 is locked, the handle case 11 is not locked in an oblique state or does not rattle. A fixing metal fitting guards the front and back of a machine screw 26 by a fixed piece 14a in the longitudinal direction of the cylindrical body of the handle 13 to heighten safety against the destruction of the lock carried out by drilling on a front side.

Filed: 1986-05-29
Abstract: PURPOSE:To eliminate the useless consumption of traction oil by turning a trunnion together with power rollers as the speed change ratio varies and lubricating the content part by the traction oil. CONSTITUTION:Traction oil is supplied to the contact part between a power roller 24 and input and output discs 21 and 22 from a lubrication hole 28b formed at the upper edge part of a trunnion 28.

Title: Color liquid crystal display element
Inventor: SAITO TAKESHI
IPC: G02F1/1335
Filed: 1990-05-16
Abstract: PURPOSE:To obtain the color liquid crystal display element having uniform display quality by forming the transparent picture element electrodes formed in correspondence to color filters slightly smaller than the size of color filters. CONSTITUTION:A liquid crystal material is sealed between transparent glass substrates 1 and 7, by which a liquid crystal layer 10 is formed. The respective picture element electrodes 8 are formed to the width A slightly smaller than the width C of the respective color filters. Even if, therefore, the misregistration between the color filters 2 and the transparent picture element electrodes 8 arises after the production of the color liquid crystal display element, the area of the parts where both overlap hardly changes and is held constant as the transparent picture element electrodes 8 are narrower in width than the color filters 2. The characteristics, such as transmittance of light and the brightness of the screen, are consequently prevented from fluctuating among products. The liquid crystal display element having the uniform display quality is thus obtd.
