摘要： A shadow mask has a main mask and an auxiliary mask overlapped on the main mask. Electron beam passage apertures formed in the main mask and the auxiliary mask are arranged at given pitches in the direction of a major axis. Each electron beam passage aperture of the auxiliary mask is a communicating hole, which is formed of a smaller hole in that surface of the auxiliary mask which is in contact with the main mask and a larger hole opening in the opposite surface of the auxiliary mask. The smaller and larger holes of each electron beam passage aperture of the auxiliary mask have their respective central axes extending coaxially with each other and substantially at right angles to the surface of the auxiliary mask in the direction of the major axis.

摘要： A semiconductor laser device includes a p-InP cladding layer, an active region, a first n-InP cladding layer, a second n-InP cladding layer, and an n-InGaAsP cladding layer with a thickness between 0.05 μm and 0.3 μm, sandwiched by the first and second n-laP cladding layers and laminated at a position closer to the active region than a position at which optical intensity of a near-field pattern of laser light emitted from the active region becomes substantially zero. The semiconductor laser device exhibits a small reduction in the optical output even when a large current flows, and has a high slope efficiency without changing the near-field pattern a great deal.

摘要： A collective erasure type nonvolatile semiconductor memory device which allows use of redundant structure to word lines is provided. A row address buffer having address converting function simultaneously selects a plurality of physically adjacent word lines from a memory array in programming before erasure. Programming before erasure is effected on the memory cells on the simultaneously selected word lines. Even when physically adjacent word lines are short-circuited between each other, programming high voltage can be transmitted to the defective word lines, as these word lines are selected simultaneously. Therefore, the memory cells on the defective word lines can be programmed before erasure, so that over erasure at the time of collective erasing operation can be prevented. Thus, redundant structure for replacing defecting word lines by spare word lines can be utilized.

摘要： A foldable electronic print board copies or records, on recording paper, various patterns of information, including letters, numerals, images, etc., which have been handwritten on a writing sheet. The foldable electronic print board has a pair of hinged cases housing the writing sheet, and a printer for printing the handwritten information on the recording paper. The printer is detachably mounted on the cases across the axis about which the print board is foldable, to keep the print board unfolded. Since the printer itself is used to hold the print board unfolded, no dedicated holder or holders are required to be fixed to the cases. The printer is located at the geometric center of the print board for thereby making the print board stable in use.

摘要： In a semiconductor integrated circuit such as a semiconductor memory device capable of operating in a special mode in addition to a standard operation mode, a high voltage detection circuit 10 detects a high voltage applied to one of control signal input terminals CS and outputs a detection signal HV to a special mode circuit 14. The special mode circuit 14 outputs a switch signal CO to a switching circuit 11 in response to the detection signal HV. The switching circuit 11 connects an input/output buffer 7 to a latch circuit 12 in response to the switch signal CO. A special mode code MC is applied to input/output terminals DT and transmitted to the latch circuit 12 through the switching circuit 11. A special mode decoder 13 decodes the special mode code MC which has been latched by the latch circuit 12 and outputs a signal for specifying the special mode to a control circuit 8. Operation in the special mode specified by the control circuit 8 is executed. By detecting a confirmation signal CS applied to one of the control signal input terminals CS during the execution of the special mode, the special mode code MC which has been already latched by the latch circuit 12 can be outputted from the input/output terminals DT.

摘要： A semiconductor memory device of erasable programmable rear only memory type is disclosed the memory device has a pair of memory cell arrays between which a differential amplifier is provided. Each of the memory cell arrays has a current-to-voltage converter circuit associated therewith. When a memory cell in either one of the pair of memory cell array is selected, a bit line being coupled to the selected memory cell is charged by one current-voltage conversion circuit, while at the same time at least one bit line in the other memory cell array where no memory cell has been selected is charged by the associated current-voltage converter circuit at arrayed different from the bit line coupled to the selected memory cell. A differential amplifier senses and amplifies a potential difference between the charged bit lines to provide a high speed read-out of the memory device.
