Title: Semiconductor memory device
Inventor: KUBONO SHIYOUJI
IPC: G11C17/18
Filed: 1987-03-16
Abstract: PURPOSE:To accelerate and stabilize a readout operation, by providing two pairs of bias circuits and a differential amplifier circuit constituted of MOSFETs and supply reference currents or readout currents to a dummy circuit and a common data line, respectively. CONSTITUTION:A vertical ROM sense amplifier SA is constituted of first bias circuit consisting of MOSFETs Q6-Q8 and second bias circuit consisting of MOSFETs Q9-Q11 which supply the readout currents or the reference currents to a common data CD and a dummy data line Dd, and the differential amplifier circuit consisting of MOSFETs Q1-Q4 which receives the output signals of those circuits. Also, a selecting and a storing MOSFETs ETQm for dummy coupled with the line Dd are formed adjacently to a selecting and a storing MOSFETs ETQm in column selection circuit respectively. In such a way, the readout operation of a vertical ROM can be accelerated and stabilized though comparatively large capacitive load is coupled with the common line CD.

Title: Inspecting method for wiring pattern of printed wiring board
Inventor: SATO HIROYASU
IPC: G01N21/88
Filed: 1990-03-09
Abstract: PURPOSE:To inspect the printed wiring board at a fast processing speed with high reliability by irradiating the printed wiring board with fluorescent light which has long wavelength enough to attenuate reflected light from a writing pattern on the reverse surface of the wiring board almost completely in the insulating base material of the wiring board so that the reflected light does not reach a photodetection part. CONSTITUTION:An internal layer plate 9 which has wiring patterns 8 formed on both surfaces of the translucent insulating base material 7 is placed on an XY table 10 which is movable in an X and a Y direction. Then the white fluorescent light from a fluorescent light generation part 11 which is arranged above is passed through a filter 12 to obtain light 13 close to red light, which moves and irradiates the entire top surface of the internal layer plate 9 continuously. Its reflected light 14 is detected by the photodetection part 16, whose output electric signal is processed by an image processing unit 17 to recognize and evaluate an image. Consequently only the reflected light from the wiring pattern on the top surface can be extracted purely, so the need for the reflected light removing process for the reverse surface pattern is eliminated. Further, virtual information is reduced.
Patent JP-S63225825-A (JP)
Title: Inclusion relation inspection system
Inventor: WADA MITSUNORI
IPC: G06F12/00
Filed: 1987-03-16
Abstract: PURPOSE:To speed up a processing by first comparing the index values of index records with each other at the time of inspection and comparing records which generate the index value with each other only at the time of coincidence between index values. CONSTITUTION:Before inclusion relations are inspected, a converting means 2 converts respective attribute values of records of a file to be inspected to binary values and outputs them to an OR operating means 3. The OR operating means 3 operates OR among binary values corresponding to all attribute values of one record bit by bit to obtain the index value. An index record generating means 4 pairs the index value from the OR operating means 3 and a pointer to generate the index record. In the case of execution of inspection of inclusion relation between two files, index records are compared with one another, and records which generate the index value are compared with each other only when index values coincide with each other. Thus, the size of the file of index records is smaller than the original file, and the inspection time is shortened since the number of records to be directly compared is sufficiently small.

CONSTITUTION:An opening part 4a having about 180 deg. opening as a light transmitting part is formed on the 1st rotating plate 4 and an opening part 5a as a similar light transmitting part is formed also in the 2nd rotating plate 5. When current is made to flow into a driving coil 16, a housing 12 is moved in the right and left direction in accordance with the direction and size of the current as shown in the figure. Since a pin 13 is moved in a cam groove 11, the housing 12 interrupted at its rotation by a shaft 7 and a D cut part and a boss, i.e. the 2nd rotating plate, are relatively rotated. Since the shaft 7 and the 1st rotating plate 4 are fixed by the boss 8, the 1st rotating plate 4 and the 2nd rotating plate 5 are relatively rotated and a practical, i.e. a slit width, opening part formed by both the opening parts 4a, 5a is changed so that the shutter time is changed.

Title: Gas/liquid contact device
Inventor: FUJII MASUMI
IPC: B01D53/34
Filed: 1993-03-19
Abstract: PURPOSE:To increase a contact efficiency between gas and liquid significantly by selecting between the shapes of a horizontal cross-section of a packing such as (A) a circle, (B) an arc or the continuous bond of arcs, and (c) a straight line which does not cross the other or a straight lien which does not come in contact with the other. CONSTITUTION:The gas/liquid contact device has a gas/liquid contact surface formed by a vertically arranged packing 2. So many gas/liquid contact surfaces are arranged in such a manner that the surface is positioned in parallel with the flow of a gas in the gas/liquid contact device. A liquid supplied from the top of the packing 2 is allowed to flow down along the gas/liquid contact surface and the gas is supplied from the bottom so that the gas is allowed to come in contact with the liquid. The horizontal cross-section of the packing 2 is of a shape selected among (A) a circle, (B) an arc or the continuous bond of the arcs, and (c) a straight line which does not cross the other or a straight line which does not come in contact with the other. Consequently, the liquid flowing down on the gas/liquid contact surface spreads extensively over the contact surface instead of running down in the form of a thread. Therefore, a flow-down retention time is long and resultantly, the gas/liquid contact efficiency is significantly increased.
