IPC: G03F1/30
Filed: 1991-10-21
Abstract: PURPOSE:To easily verify the design data on the phase shift mask for semiconductor integrated circuit transfer at low cost in a short time without actually manufacturing any mask. CONSTITUTION:A desired pattern is processed by a bit map expanding circuit 1 and stored in a memory circuit 2. The light shield pattern and shifter pattern of the phase shift mask are processed by bit map expanding circuits 3 and 4 respectively and stored in memory circuits 5 and 6. Both image signals are put together by a memory circuit 7 and processed by a mask optical image forming circuit 8 into an optical image, which is stored in a memory circuit 9. A comparative arithmetic circuit 10 verifies images of both the memory circuits 2 and 9.

Title: Logic simulator equipped with test coverage display function
Inventor: NAKANISHI KENTARO
IPC: G01R31/28
Filed: 1990-10-09
Abstract: PURPOSE:To obtain a logic simulator that indicates time of executing direct current characteristic test or the like immediately after the execution of a logic simulation by using a separate calculation formula or the like to define a signal condition for a particular element when outputting changing time of signal of each element. CONSTITUTION:First, a logic circuit drawing 31 as element connecting information by design language is converted into logic simulator input data of table format. Further, for the execution of simulation, an input signal, simulation control, and test condition are inputted in a logic simulator. Here, since it is needed to know time of executing output voltage L level test for output pin d, test condition such as d=0 is input. The logic simulator uses algorithm such as table driven method to trace each signal change and outputs a result while referring to test condition at all times. With this, the development time taken for a LSI test program can be shortened.

Title: Projection type display device
Inventor: MITSUTAKE HIDEAKI
IPC: G03B21/00
Filed: 1991-10-21
Abstract: PURPOSE:To enable increasing of the brightness at both the center and periphery of a screen by illuminating the peripheral part of a body to be illuminated with the luminous fluxes from two high-brightness light emitting regions. CONSTITUTION:The reverse tracing light from the axial point on the screen is nearly converged to the focus of a reflector 2 by the shape on the exit side of the reflector 2 and a condenser 2'. Then, the illuminating luminous flux having the highest brightness is obtd. on the axial point by disposing the 1st high-brightness region alpha of a light source into the focus of the reflector 2. On the other hand, the partial luminous flux l221 falling to a part of the reverse tracing light from the off-axial point is refracted by a curved surface 2'-b and is converged to the high-brightness region alpha of the light source and the partial luminous flux l221 is made into the illuminating luminous flux of the high brightness. On the other hand, the partial luminous flux l221 does not pass the curved surface 2'-b of the condenser 2' and, therefore, the convergence to the other high-brightness region alpha' of the light source is maintained. The high-brightness region of the illuminating luminous flux of the reverse tracing light from the off-axial point is increased in this way and the illuminance of the image plane is increased.

Abstract: PROBLEM TO BE SOLVED: To provide the image data conversion method and the image data converter where it is suppressed that a modulation frequency at a medium density gets too high and a gradation number of an output image and stability are prevented from being decreased while keeping compatibility among a counter moire performance, high resolution and high gradation. SOLUTION: A binarization processing error is calculated at a position of a picture element processed already in a 1st step S111 and recorded, and the received picture element value is corrected by the error in a 2nd step S112. Then a threshold level processing is applied to the input picture element value corrected in a 3rd step S113 and a modulation period in the vicinity of a position of a noted picture element of the obtained binary digital image data is estimated in a 4th step S114. Furthermore, in a final step S115, in the case that the modulation period of the binary digital image data is estimated to be short, an output at the position of the noted picture element is decided the same as the processed picture element in the vicinity regardless of the result of threshold level processing.

Abstract: PURPOSE:To effectively rewrite the set-up information by providing a means which rewrite sequentially the set-up information stored in an EEPROM after the set-up information stored in a RAM is rewritten. CONSTITUTION:A CPU 1 serves as an arithmetic processing means which sets a function in an ON state of a power supply in accordance with the set-up information. An EEPROM 2 serves as a storage means which can hold the store information even in an OFF state of the power supply. A RAM 3 serves as a storage means which reads the set-up information out of the EEPROM 2 and stores it. Then a ROM 4 serves as a storage means which stores the firmware. The set-up information stored in the EEPROM 2 is sequentially rewritten by the CPU 1 after the set-up information stored in the RAM 3 is rewritten. In such a constitution, the set-up information stored in the store means like the EEPROM 2, etc., can be rewritten with no input required for a write command, etc. Then the rewriting efficiency is improved for the set-up information.

Title: Cr oscillation circuit
Inventor: KATO TAKAYUKI
IPC: H03K3/354
Filed: 1993-11-01
Abstract: PURPOSE:To prevent a voltage higher than a power supply voltage or lower than a ground potential from being generated at the input part of an inverter circuit on a first stage by dividing the potential change at the input part of the inverter circuit on the first stage with two capacitors. CONSTITUTION:When the potential at the output part (point (c)) of an inverter circuit 13 on the final stage is assumed as H, first and second capacitors 15 and 16 are charged through a resistor 14. The potential at the input part (point (a)) of an inverter circuit 11 on the first stage is increased with the charge of the capacitors 15 and 16 and exceeds a threshold voltage VTH of the first inverter circuit 11. The potential at the output part (point (b)) of an inverter circuit 12 on the second stage is turned to H but divided by the capacitors 15 and 16 and the potential at the point (a) becomes an expression I. In this case, when the potential at the point (b) becomes H, the potential at the point (c) becomes L, and the charges stored at the capacitors 15 and 16 are discharged through the resistor 14. With this discharge, the potential at the point (a) is dropped and lowered rather than the threshold voltage VTH of the inverter circuit 11. Then, the potential at the point (b) is turned to L but divided by the capacitors 15 and 16 and the potential at the point (a) becomes an expression II. When the potential at the point (b) becomes 'L', the potential at the point (c) becomes 'H'.

Title: Air bag
Inventor: INABA KAZUO
IPC: B60R21/16
Filed: 1993-11-02
Abstract: PURPOSE:To unfold an air bag quickly and flatly. CONSTITUTION:Both peripheral parts between an upper ground fabric 15 being opposed to an occupant and a lower ground fabric at the side of a steering wheel body are sealed up with each other, forming a bagy air bag 11. A gas inlet port 18, where an inflator spraying gas is inserted in, is formed almost in the central part of the lower ground fabric. Both these upper and lower ground fabrics are sewed up together at respective sewing part 24 in several spots. Each sewing part 24 is made up into an almost V-shaped form extendedly installed with a sewing body part 26 toward the outer circumferential side from a base part 25 installed at the inner circumferential side of the air bag 11. In this connection, an opening angle theta of this sewing body part 26 should be set to about 20 degrees. When gas is sprayed out of the inflator, the air bag 11 is flatly unfolded, and then thread of the sewing part is successively cut off from the base part 25 into being inflated to the occupant side. Therefore, such a fear that the sewing part is cut at a stretch is thus preventable from occurring.
