Title: Measuring method for thickness of coated film
Inventor: TABUSE KENJI
IPC: G01B15/02
Filed: 1980-04-26
Abstract: PURPOSE: To continuously measure the thickness of coated film by a nondestructive inspection independently of the existence of a plating or the kind of paint by a method wherein a specified substance is uniformly dispersed into a paint, and the concentration of said substance in the coating film is measured by using radioactive rays.  
     CONSTITUTION: One or more substances are selected from minerals such as titanium oxide (TiO 2 ), barium sulfate (BaSO 4 ), calcium carbonate (CaCO 3 ) or the like, which are specified substances having no adverse effect on the color tone and performance of a coating film, and one of the given compounding amounts thereof, which are individually designed with respect to the kinds and color tones of various paints, is added to a paint and uniformly dispersed thereinto before being applied. The concentration of said minerals included in the coated film is measured by using radioactive rays and converted into a coating film thickness by using a calibration curve prepared previously to obtain the thickness of the coated film. Thereby, the thickness of the film can be continuously measured in a nondestructive manner independently of the kind of blank plate, the existence of a plating, the thickness thereof or the kind of paint.

Filed: 1991-03-20
Abstract: PURPOSE:To normally operate a semiconductor storage device as an input protection circuit even when negative voltage is applied to the input circuit of the device by connecting the gate of a N channel type transistor to the circuit board of the device. CONSTITUTION:A semiconductor storage device 1 consists of an input circuit part 2, a storage circuit part 3 and an input protection circuit part 4. The input protection circuit 4 incorporates a resistor 8 in addition to the N channel type transistor 5, and a circuit board 9 comprises a P channel type well. Because of such construction of the input protection circuit 4, the negative voltage in the range of -2.0V to 3.0V is always applied to the gate of the N channel type transistor. Accordingly, even when a signal voltage of about -2.0V is applied to the input circuit of the storage device, the potential difference will not take place between a gate G and a source S of the N channel type transistor of the input protection circuit and thus, the input protection circuit can operate normally.

Filed: 1985-03-19
Abstract: PURPOSE:To brake by a small-sized power-saving circuit with high reliability by shortcircuiting a motor coil by a diode and a transistor when a power supply is interrupted. CONSTITUTION:While power is supplied from a power source 1, a transistor 11 is turned ON, and a transistor 13 is turned OFF. When a power supply is interrupted from the power source 1, the transistor 11 is turned OFF to open the base of the transistor 13. A shortcircuiting current is flowed to the transistor 13 through diode 4 and 8 by the induced voltage of a motor coil 3. At this time, since the base of the transistor 13 is opened, a base current is supplied through a resistor 12, and the transistor 13 is turned ON. Even if the induced voltage is generated in a reverse direction, a shortcircuiting current is flowed through diodes 4-6 and 7-9.

Title: Varying method for jump instruction
Inventor: TAKAGI TAMOTSU
IPC: G06F9/45
Filed: 1982-04-05
Abstract: PURPOSE:To shorten program length effectively and to utilize a memory efficiently, by representing a possible jump instruction among jump instructions in a source program by a short jump instruction having short words length. CONSTITUTION:When a computer alters a jump instruction, one page and the ending address of a pre-read are set respectively and one line of statements is read out of a source file to allow an address counter to go up by the number of bytes corresponding to the read contents. The jump destinated operands of jump instructions are stored corresponding to the instructions. Further, when there are labels, they are stored successively and a decision on whether a jump destination operand using a label as its jump destination is stored or not is made to store the address of a corresponding jump instruction according to the decision result. For every corresponding jump instruction, the address counter goes down by the difference between a long and a short jump instruction and the jump instruction is altered into the short jump instruction by referring to the ending address of one address when the address counter reaches the pre-read ending address.
