Title: Semiconductor memory device
Inventor: SENOO KATSUNORI
IPC: H01L21/82
Filed: 1991-01-16
Abstract: PURPOSE:To surely detect errors and further to easily obtain the information on the presence or absence of a redundancy relief, etc., by preventing the fluctuation in signals even if redundancy circuits are used with the semiconductor memory device to be subjected to a parallel test (multibit test). CONSTITUTION:The redundancy cell sections RC1 to RC4 for relieving the whole column are disposed in each of units UA1, RA1 to be integrally activated at the time of the parallel test. The fluctuations in the timing of the signal input to the comparator circuit 11 which makes error decision at the time of the parallel test are eliminated by matching the unit of the redundancy relief with the unit of the parallel test. The presence or absence, etc., of the redundancy relief are known simply by viewing the addresses in the parallel test and the chip area is reduced by disposing the redundancy cell sections RC1 to RC4 within the unit RA1 respectively adjacent to the ordinary cell array sections MAn1 to MAn4.

Title: Detector for skew of recording medium
Inventor: MURAYAMA TOMIO
IPC: B65H7/08
Filed: 1981-02-05
Abstract: PURPOSE:To improve reliability of a recorder by a method wherein plural detectors are provided on the recording unit of the recorder so that an oblique transfer, that is a skew, is detected and corrected reliably through a time difference for the tip of the recording paper until it reaches to the detector. CONSTITUTION:When recording paper 10 is transferred askew the recording paper can not be detected by left and right photosensors 13 and 14 located in the vicinity of feeld rollers 11 and 12 simultaneously. If the recording paper 10 is skewed clockwise, the recording paper 10 is detected first by the photosensor 13, and the recording paper 10 is detected by the photosensor 14 followed by a delay corresponding to an extent of a skew. Then detecting signals of both the sensors 13 and 14 are applied to a timing controller 15 in this order, an output signal is supplied to a right feeder driver 17 from the controller 15 by a predetermined time corresponding to its signal difference, and then the skew of the recording paper is corrected also by supplying an output signal to a left feeder driver 16.

Title: Position detecting method for different kinds of metals on metallic material
Inventor: OTAKE HIROO
IPC: G01N27/12
Filed: 1985-01-29
Abstract: PURPOSE:To measure with a high accuracy a dislocation of an inlay material, and also to hold a position of the inlay material in a prescribed dimension accuracy by measuring an output variation of a sensor corresponding to the dislocation of different kinds of metallic materials. CONSTITUTION:A base material 1 advances in the direction as indicated with an arrow. An inlay material tape 2 advances along the base material 1, and goes into a clad roll 4 by being guided to a prescribed position by an inlay positioning tape guide 3. The clad inlay clad material passes through position detecting sensors 6, 6' which have been installed just behind the clad roll 4. When the position of the inlay material 2 conforms with a prescribed position, an output of the sensor is set to zero, and an output variation generated by a shift of the position of the inlay material 2 is recorded by a recording meter 8 through a controller 7. In this way, the position accuracy of the inlay material 2 can be held extending over the overall length.

Title: Data switching device
Inventor: ISOGAWA YOICHI
Filed: 1986-01-27
Abstract: PURPOSE:To efficiently operate a main processor by classifying all data passing line interfaces by data separation and integration processing devices according as the processing in the processor is required or not and integrating processed data and storing data which is not processed. CONSTITUTION:A data switching device is provided with plural line interfaces 1o-1m...no-nm to lead all of received data to separation and integration processing devices 1-(n). Each of plural data separation and integration processing devices 1-(n) separates data, which is processed by a network layer, out of received data and transfers this separated data to a memory device 200 through a memory bus 400 and stores a data packet main part in a data storage device 100. Data stored in the memory device 200 are processed and edited by a main processor 300. The main processor 300 selects an outgoing line in accordance with the contents of data and reads data from the memory 200 through the data separation and integration processing devices (n) and reads and transmits a corresponding packet from the storage device. Thus, the main processor is operated efficiently.

Title: Photodetector
Inventor: KITAGAWA MASATOSHI
IPC: H01L31/0248
Filed: 1983-02-01
Abstract: PURPOSE:To reduce a DC component in a signal output generated in a photo- detecting section, and to generate a large AC signal by coating sections except the photo-detecting section with an amorphous germanium semiconductor layer. CONSTITUTION:A P type amorphous silicon layer 22, an amorphous silicon layer 23 containing no impurity and an N type amorphous silicon layer 24 are formed on a substrate 21 consisting of stainless steel. Transparent electrodes 25, 26 are isolated and formed and used as photo-detecting sections, and amorphous germanium layers 27 are formed to sections except the electrodes 25, 26. Since beams do not reach to the amorphous silicon layer 23 in sections where the amorphous germanium layers 27 are formed and the otical conductivity of the layer 27 is smaller than amorphous silicon, optical outputs in sections except the photo-detecting sections are reduced, and a photo-detector, the performance of an output waveform therefrom is high, can be completed.

Title: Water barrier stratum
Inventor: NISHIYAMA KATSUE
IPC: E02B3/18
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To prevent the influence of ground subsidence or the like, and also prevent the occurrence of cracks in the water barrier stratum by an underground stratum or the influence of dry contraction by supporting a water barrier stratum by a ground stratum consisting of blending low penetration material being swelled by a supply of aggregate and moisture and curing material. SOLUTION: Since an underground stratum 21 is blended with aggregates using site generated earth, bentonite 6, and cement, and cement as being curing material of underground stratum 21 has a more blending rate than that of a water barrier stratum, a sufficient mechanical strength is given to support a water barrier stratum 22. Moreover, since a compression strength is intensive, it has a water barrier ability similar to the conventional one. Also, since the compression strength is intensive, even in the case where a base ground 1 is weak, there takes place no shift or the like on the water barrier stratum 22. Furthermore, it the ground 1 sinks, the water barrier stratum 22 is supported by the strengthened underground stratum 21, so that the water barrier stratum 22 and water barrier sheet 3 never break.  This can prevent the influence of ground subsidence or the like, or the influence of dry contraction.
