Title: Semiconductor intergrated circuit
Inventor: HONGOU TOYOHIKO
IPC: H01L27/04
Filed: 1982-09-06
Abstract: PURPOSE:To prevent the influence of power variation entailing the operation of a logical circuit, etc., upon an oscillation circuit, by separating a supply system for clamp voltages supplied from a constant voltage circuit to the oscillation circuit, logical circuit, etc., into the oscillation circuit and other circuits. CONSTITUTION:The constant voltage circuit 1 connected to a battery power source B such as a lithium battery supplies clamp voltages V1 and V2 to the oscillation circuit 2 and other circuits, i.e. dividing circuit 3, logical circuit 4, etc., separately through power source lines l1 and l2 formed individually. The clamp voltage V2 of the power source line l2, is not inputted to an input terminal of an operational amplifier 1a and only the clamp voltage V1 of the power source line l1 to the oscillation circuit 2 having relatively less voltage variation is inputted thereto. Therefore, even if the voltage V2 of the power source line l2 varies owing to a transient current during the operation of the logical circuit 4, the output voltage of the operation amplifier 4 never varies.

The printed surface of an original sheet consisting of base material 4, onto which images 5 such as formats and the like have been printed in advance with subliming dye ink or subliming dye-containing toner, is put on the plastic film 3 of said laminated sheet so as to contact the printed images with the film 3 in order to sublimation- transfer the subliming dye of the printed images and, after that, to peel off the original sheet to form subliming dye images 6. The resultant format images consisting of subliming dye formed as mentioned above cannot be erased with an eraser, owing to the strong penetrating force of dye molecules.

Abstract: PROBLEM TO BE SOLVED: To remove a stencil board by only pulling and seperating without damaging a cured coated material, by using a foamed plastics material having specific values in tensile strength and elongation as the main body of the stencil board for forming a concavo-convex pattern on the surface. SOLUTION: As a stencil board 1 used for obtaining a wall-joint pattern by spraying a coating material on the thick-paper-made stencil board 1 with the punched-out wall-joint pattern stuck on a wall or the like and then by separating the stencil board 1, a foamed plastics main body 2 with an adhesive layer 3 on the lower surface covered with a separation film 4 on the said layer 3 is employed. The main body 2 should have the tensile strength of 2,000 kPa and the elongation of not less than 250%. The back surface of the stencil board 1 may be coated with a sticking agent to be stuck to the coating surface. Such stencil board 1 is easily separated, because the width of the part existing perpendicular to a stretched direction becomes narrower due to higher elongation.

Filed: 1986-07-01
Abstract: PURPOSE:To detect the input of continuous data in a simple constitution by using a comparator, plural FF, plural gates, a pulse generator, a control signal generator, etc. CONSTITUTION:An AND gate 3b is controlled by a control signal 5a received from a control signal generator 5 via an OR gate 3a or by the output of a D type FF2a which is controlled by the clock given from a pulse generator 4 and has a synchronous action with the input data 11. An AND gate 3d is also controlled in the same way as the gate 3b. When signals 5a and 5b are equal to '1' and '0' respectively, the 2nd data is outputted from an output terminal 1b of a comparator 1 and therefore the output is delivered from a D type FF2b. Then the output is delivered from a D type FF2c and the 2nd and 3rd data are delivered via the FF2c when the 3rd data is delivered from an output terminal 1c. The data is outputted from the terminal 1c when signals 5a and 5b are equal to '0' and '1' respectively. When both signals 5a and 5b are equal to '0', the data are continuously outputted from output terminals 1a, 1b and 1c. Then the continuous inputs can be detected in a simple constitution that is free from a latch circuit, a counter, a timing circuit, etc.

Title: Welding material
Inventor: TAKEUCHI HIROKIMI
IPC: B23K35/30
Filed: 1982-09-08
Abstract: PURPOSE:To reduce defects by welding the painted steel plates without removing the paint coated film in the weld zone and to improve welding efficiency, by incorporating specific components in a welding material and incorporating one or both of 1 kind or >=2 kinds among Se, Te, Sb and S which are limited in weight ratios. CONSTITUTION:A welding material produced by incorporating 0.05wt% Ti in steel contg., by weight, 0.15% C, 1.0% Si and <=3.0% Mn and incorporating one or both of 0.005-0.1wt% in total of 1 or >=2 kinds selected from Se, Te, Sb and 0.04-0.1wt% S is used as a coated arc welding electrode, a welding wire for submerged arc welding or further a filler wire and a filler rod for gas shielded arc welding. The reason for limiting the chemical components lies in that if C is contained too much the corrosion resistance is poor. If Si is contained too much, the toughness is poor. A too much content of Mn results in the inferior shape of beads and poor corrosion resistance and machinability.

Abstract: PURPOSE:To selectively etch between an SiO2 layer and an Si3N4 layer and particularly to initially propose a highly selective etching of the Si02 layer on the Si3N4 layer. CONSTITUTION:An insulating film 4 between an SiO2 layer and an Si3N4 base film 3 formed on a silicon substrate 1 is etched by using S2F2/H2 mixture gas.

The deposited S and the (SN)n can be decomposed and removed at the time of ashing a resist mask 4. The SiO2 layer by an Si3N4 mask can be etched by the similar principle, and a mask selection ratio can be improved.
