Title: Semiconductor memory
Inventor: SUMIYA TSUTOMU
IPC: G11C29/12
Filed: 1982-12-29
Abstract: PURPOSE:To prevent the multiple reading and multiple writing of an address by supplying a control signal to the gates of the 2nd and the 3rd transistors (TR) during a test, and turning on the 2nd TR and turning off the 3rd TR. CONSTITUTION:A dynamic decoder circuit is provided newly with MOS TRs T1 and T2, whose gates are controlled by a scan-mode control signal SM. Namely, the signal SM is held at a low level in the scan mode to turn on the TRT1, and a point (a) is held at a high level; and the TRT2 is turned off to disconnect N channel MOS TRs M0-Mn from the point (a). Therefore, the decoder circut is never selected in the scan mode irrespective of the variation of the contents of an address register, and even when a clock phi goes down to the low level after switching from the scan mode to normal mode, the point (a) is held at the high level for all decoders, so that the multiple writing is never carried out.

Title: Manufacture of semiconductor device
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/8242
Filed: 1986-10-01
Abstract: PURPOSE:To eliminate the need for a complicate process in which a first gate oxide film is held between polycrystalline Si layers, and to prevent the generation of the difference of thermal expansion coefficients by growing the polycrystalline Si layer, to which an impurity is doped, to a layer being in contact with the oxide film in a trench in thickness of the irreducible minimum of a demand and using the polycrystalline Si layer as a capacitor electrode. CONSTITUTION:A trench 2 is formed to a substrate 1. The inside of the trench and the surface of the substrate are thermally oxidized to shape a first gate oxide film 3. DOPOS is grown in 2000Angstrom  as a first polycrystalline Si layer 4. A second polycrystalline Si layer 6 to which an impurity is not doped is grown in 7000Angstrom -1mum. The second polycrystalline Si layer 6 is etched back through RIE to expose the first polycrystalline Si layer 4 as a capacitor electrode. The oxide film need not be held between polycrystalline Si layers in two layers as seen in conventional manufacture, thus simplifying a process. The inside of the trench is buried only with polycrystalline Si, thus generating no trouble resulting from the difference of thermal expansion coefficients between the oxide film and the polycrystalline Si layer. The oxide film need not be patterned in order to take the contact of the capacitor electrode.

Title: Color image formation
Inventor: FUKUTOME TSUKASA
IPC: G03G15/01
Filed: 1982-12-27
Abstract: PURPOSE:To convert a soft copy to a hard copy with high efficiency by forming a color image by utilizing a difference of photosensitivity of an exposure part and a non-exposure part by an image forming projection of an optical signal. CONSTITUTION:Filter particles P consist of a mixed compound of three kinds of particles, are colored in three primary colors, for instance, red, green and blue, and make a colored light transmit. A filter particle layer formed on a photosensitive body 1 generates an optical signal of three primary colors when a picture signal is impressed to a color CRT 6, it is brought to image forming projection by an operation of an OPF 7 being an unmagnification image forming means, and a write exposure is executed. In this case, in a part irradiated by a red light, as for the filter particles colored in red, the adhering force to the photosensitive body 1 is weakened. The filter particles whose adhering force to the photosensitive body 1 is weakened are removed from on the photosensitive body by a developing device 8. When the filter particles which remain behind on the photosensitive body 1 are transferred onto a recording sheet S by a transfer device 9, complementary colors of blue and green of the remaining particles are developed, a red color is reproduced, and a desired color image is obtained.

Filed: 1990-09-05
Abstract: PURPOSE:To greatly reduce the amount of data required for delay analysis by extracting only a critical path from a circuit data and executing delay analysis between flip-flops connected through the extracted critical path. CONSTITUTION:First of all, the circuit data of a printed circuit board 12 loading LSI 10-1 and 10-2 is read so as to retrieve all paths 200-1, 300-1, 400-2 and 500-2 from flip-flops 14-1 and 14-2 built in the respective LSI 10-1 and 10-2 on the circuit data to input/output terminals 16-1 and 16-2 of these LSI 10-1 and 10-2. Next, the paths 300-1 and 500-2 having the both equal path terminals and the maximum signal delay are specified. Among the paths 200-1, 300-1, 400-2 and 500-2, only the critical paths 300-1 and 500-2 are extracted and this irreducible minimum data is used for following processings. Thus, the size of a region can be sharply reduced when modeling the circuit or checking the FF.

Abstract: PURPOSE:To switch view positions for a display image according to a low and a high speed by rotating part or the whole of a main reflecting member, combining it with the other reflecting member, and moving up the visual field of the display image from a display device. CONSTITUTION:The reflecting surface 6a of a reflector 6 can be switched between the position where the reflecting surface is in level with a fixed part 6a1 and the position where the surface is rotated around a shaft 6b by a specific angle. A CPU 11 turns off a solenoid 14 in low-speed operation through a vehicle speed sensor 12, but attracts a conductive piece 6c provided to one end of the excitation of the solenoid 14 in high-speed operation to rotate a movable part 6a2 counterclockwise around the shaft part 6b. Consequently, even if the low- speed operation is changed into the high-speed operation, the display image on the display device can be confirmed by the optical path formed of the movable part 6a2 of the reflector 6 rotated by the specific angle, a 1st reflecting member 8, and a 2nd reflecting member 9 while the line of sight in a driving state is maintained.
