Title: Defect detecting method for liquid crystal display device
Inventor: TAKAHARA HIROSHI
IPC: G01R31/28
Filed: 1987-03-27
Abstract: PURPOSE:To detect a thin film transistor (TR) where a short-circuit defect occurs by applying a selective signal to a source signal line and a gate signal line and measuring the current of an adjacent source signal line. CONSTITUTION:A voltage applying means 3 applies a voltage to a source signal line S2, then the selective voltage VON to a gate signal line G3, and a nonselect signal VOFF to other gate lines. A current outputted to an adjacent source signal line S3 is measured by a voltage measuring means 4. Two positions of thin film TRs where it is considered that a short-circuit defect occurs, namely, TS22 and TM22 are limited according to whether or not the voltage is present. Then currents which flow to the source signal line 3 when the selective voltage VON is applied to said gate signal lines G2 and G3 and when the selective voltage VON is applied to the gate signal lines G3 and G4 are measured. A thin film TR TS22 where a defect occurs is detected according to the comparison result between those currents.

Title: Electronic cash register device
Inventor: ITOU NAOKI
IPC: G07G1/01
Filed: 1983-04-27
Abstract: PURPOSE:To reduce the load of a cashier and at the same time to improve the reliability of an electronic cash register device by providing a pilot lamp to show automatically whether or not the registration of sale is possible in response to the sale registration enable state. CONSTITUTION:A cashier sets a register main body 2 to a ''register'' mode with a control key 11 and therefore a display driving circuit 22 works automatically to turn on a pilot lamp 6. In case the power supply switch of the main body 2 is opened since the cashier must leave a register device or when the key 11 is switched to another mode other than ''register'' to perform ''adjustment'' after the ''register'' is through, the circuit 22 functions automatically to turn on a pause pilot lamp 4. Therefore it is not needed for the cashier to turn on/off the pilot lamp and to set/unset a ''pause'' plate. This reduces the load of the cashier.

IPC: F16F15/02
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To highly sensitively measure the acceleration without mounting an acceleration sensor by measuring a drive force of a stage, measuring a relative distance between the stage and a level block, and calculating a linear sum of a value obtained by second-order differentiating the measured length value by the time and the drive force. SOLUTION: A stage 12 of the mass (m) which can be moved in one direction and a length measuring sensor 13 which is fixed to a level block 11 and positioned in the distance x1 from the reference point (o) are mounted on the level block 11 or an object to be vibration controlled. An actuator 15 which is positioned between the level block 11 and the stage 12 generates a drive force (f). The equation of the motion of the stage 12 is found and sorted to reach X"1 =(f/m)+X"s . The acceleration X"1 of the level block 11 can be thus found by the equation as the sum of a value obtained by dividing the stage drive force (f) by the mass (m) of the stage 12 and a value X"s obtained by second-order differentiating the measured value Xs of the length measuring sensor 13 by the time.  When a linear motor is used as the actuator 15 in measuring the drive force (f), the measured value of the current of the motor is used. For example, a controller 18 executes this operation.

Title: Method for analyzing microelement
Inventor: NAKAJIMA YUKIKO
IPC: G01N21/31
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To analyze a trace of silicon in a solution including fluorine with high sensitivity, by adding boron as a modification agent when a sample is analyzed by a frameless atomic absorption spectrometer. SOLUTION: For instance, hydrofluoric acid is added to a trace of silicon of a cleaning chemical solution on a wafer surface, which is separated and condensed, thereby obtaining a sample solution including fluorine. When the silicon in the sample solution is to be analyzed by frameless atomic absorption spectrometry, preferably, an aqueous solution of boron is added to an atomization part and dried hard beforehand, and then boron is added to the sample before the sample is measured. The boron is used generally in a form of the aqueous solution and the amount of boron added to the atomization part is generally approximately 0.4 μg. An addition concentration to the sample is required to be 0.25 times or more a concentration of the fluorine in the sample. Although the effect may be insufficient if the boron is added too small, an excessive amount is not preferable.  According to the method, the silicon is prevented from volatilizing when a solvent evaporates in the presence of the fluorine, thus enabling analyses with high sensitivity.
