Title: Semiconductor memory
Inventor: IRIKITA SHIGEYOSHI
IPC: G11C11/411
Filed: 1987-10-30
Abstract: PURPOSE:To realize a large capacity and high speed by using a field effect transistor as a load for a bipolar transistor which forms a memory cell, and varying load impedance in selection and non-selection. CONSTITUTION:The bases and the collectors of the bipolar transistors (Tr)Q1 and Q2 are connected by crisscrossing, and they are connected to a holding current line WB1, and also, emitters on the other sides are connected to digit lines D1 and D2. To the collectors of the Trs Q1 and Q2, the drains of the FETs Q3 and Q4 are connected, and also, the sources are connected commonly to a power source G1. It is possible to set impedance at 5kOMEGA at the time of selecting a large voltage VGS between the gate and source, and to increase it to 20kOMEGA at the time of selecting a small voltage in the non-selection. Also, since a device is held by a small holding current IH in the non-selection and low impedance is generated in a load in the selection, no saturation occurs even by permitting a large readout current ID to flow compared with a case in the non-selection. By permitting the large readout current at the time of selection to flow, it is possible to realize to make a memory large in capacity.

Abstract: PURPOSE:To perform exactly, quickly and easily a measurement by an enlarged image, irrespective of an attached position of an object to be measured, by inclining and correcting a figure of an enlarged image of a monitor device to a reference figure. CONSTITUTION:An illumination optical system 14 executes a light irradiation to an object to be measured 12 which has been placed on an object placing base 10. An enlargement optical system 16 enlarges a part to be measured of the object 12. A moving mechanism 18 moves relatively the base 10 and the optical system 16 in order to enlarge a prescribed object part. A monitor device 22 is coupled to the optical system 16 through, for instance, a TV 20, and reflects an enlarged image of the object part. As a result, a size and a shape, etc. of the object are derived by bringing the enlarged image to, for instance, an edge detection processing. Also, an angle difference of an attached angle of the object 12 against the base 10, and a reference relative angle of both of them is derived by evaluating the enlarged image by the optical system 16, and operating an angle difference discriminating means 24. An angle difference signal of an output of this means 24 is supplied to an angle correcting means 26. An operator executes an inclination correction so that a figure of the enlarged image always becomes similar to a reference figure.

Title: Detector for gap of folded box joint
Inventor: TAKENAKA HIROYUKI
IPC: G01B11/14
Filed: 1984-12-26
Abstract: PURPOSE:To detect abnormal joint of a corrugated board box immediately after folding or jointing operation in a box manufacturing machine, by arranging detecting blocks along a running path of a folding corrugated board box on which both ends thereof are jointed and measuring a gap of the jointed portion. CONSTITUTION:When a folded corrugated board box 1 passes a detecting block 7, a gap G of the jointed portion runs on a slit 8 of the block 7. At this moment, a beam of light from the source 12 is irradiated from an irradiating groove 9 through a light-irradiating optical fiber 11 and the beam located outside the joint gap is reflected as shown by the arrow P to be received by a light- receiving optical fiber 13, however, that on the joint gap does not receive the reflected beam as shown by the arrow Q and consequently, the beam remains unreceived by the light-receiving optical fiber 13. Consequently, such reflected beam, out of the light-receiving optical fibers 13, coming from outside of the joint gap becomes 'bright' and that coming from the gap becomes 'dark' and consequently, this bright and dark distinction is identified by the light- receiving element 15 and when a value of the gap dimension G exceeds the allowable limit, then a signal is issued informing the abnormality of the quality.

Title: Pressure-sensitive copying paper
Inventor: MATOBA MOTOSUKE
IPC: B41M5/155
Filed: 1988-10-31
Abstract: PURPOSE:To obtain a high density developed color image without lowering adhesive strength even when the amount of the proper binder of an electron acceptive coupler layer is reduced by containing synthetic hectorite clay being a white powder and easily solated or gelled by water in the electron acceptive coupler layer. CONSTITUTION:Synthetic hectorite clay is contained in a layer containing an electron acceptive coupler and has the same structural formula as a natural hectorite clay and is composed of a white powder and dissolved in water up to about 10% and Laponite B, RD, XLG form a gel while Laponite S, RDS, XLS form a sol. When synthetic hectorite clay is contained in the coupler layer, the amount of a binder necessary for obtaining the same adhesive force may be set to about 60% that of the binder containing no hectorite. The electric bondability due to synthetic hectorite clay is developed between the coupler and the binder by the structural charge specificity possessed by the primary plate-shaped particles peculiar to the synthetic hectorite clay and, as a result, the amount of the binder can be reduced by the quantity corresponding to the bonding force possessed by the hectorite clay.
