IPC: H02H6/00
Filed: 1987-06-15
Abstract: PURPOSE:To enable an overload to be operated for a long time for working the capacity of a transformer always to the maximum degree even in a system where a load is frequently fluctuated, by correcting the temperature setting value of a temperature discriminating equation according to the fluctuation of the load. CONSTITUTION:From the scale of the input current of a protective relay, it is detected that a transformer is put in an overload state, and by convergence arithmetic operation system for example, estimated arithmetic is performed on a time from the overload till the winding maximum point temperature of the transformer comes to a threshold value. On this arithmetic operation, a temperature setting value after correction which is computed every time a load is fluctuated is to be used, and the time for coming to the value finally is computed, and after that, a time with a subtracted fixed excess time is found, and an overload operation within the time is allowed, and after the lapse of the time, by the generation of alarm and the interruption of the load, the load is protected.

Title: Manufacture of curl resistance heat sensitive stencil printing base paper
Inventor: SANO TADAO
IPC: B41N1/24
Filed: 1989-06-15
Abstract: PURPOSE:To prevent curling of a film by controlling moisture of a porous sheet and temperature of the film, and controlling tensions of the sheet and the film. CONSTITUTION:If a film side is curled laterally in a step of laminating a heat sensitive stencil printing thermoplastic resin film, moisture is absorbed to the sheet to elongate it. On the other hand, the film is cooled, and both are laminated in a shrinked state. The obtained base paper is shrinked as the paper for forming it is dried, but the film is elongated in the process of returning to an ambient temperature. Accordingly, both are balanced to prevent it from curling. Even if the sheet side is curled laterally, the curl is prevented by the similar operating mechanism. The elongation and shrinkage of both for forming the base paper can be balanced by controlling the tensions of the sheet and the film even against the vertical curl, and curling is prevented.

Title: Semiconductor integrated circuit device
Inventor: MOROOKA KIICHI
IPC: H01L27/04
Filed: 1990-06-07
Abstract: PURPOSE:To stably bias a substrate to a desired negative potential without consuming wasteful power by setting at least one of H and L levels to a third potential shifted from a second potential obtained from a first potential obtained from a first power source or a second potential obtained from a second power source by a predetermined potential by voltage signal output means. CONSTITUTION:A switching signal phi2 is oscillated at H and L levels between a potential Vd and a set level VSS in a switching circuit 2 based on an oscillation signal phi1 of an oscillation circuit 1. Thus, a signal phi3 of the other electrode side of a capacitor 3 is oscillated, but its upper limit is clamped to the threshold voltage Vt of a transistor 4. On the other hand, since its lower limit is not limited, it is lowered to (Vt - Vd) by the capacity coupling of the capacitor 3. As the signal phi3 is varied, a substrate voltage VS is fixed substantially to the vicinity of (2Vt - Vd). Thus, a voltage conversion circuit 21 is provided between a power source VCC and a switching circuit 2', and the H level of the circuit 2' is level-shifted from the VCC to the stable Vd, thereby altering the voltage VS.

Title: Film thickness measuring device
Inventor: OOGUCHI TETSUYA
IPC: G01B15/02
Filed: 1982-08-31
Abstract: PURPOSE:To measure easily the thickness of metallic foil by radiating beta rays to the front side of a laminate plate having metallic foil laminated on both surfaces while bringing metallic foil of the same material with the metallic foil into contact with the rear-surface metallic foil, and then measuring the dosage of beta rays scattered backward by a Geiger-tube. CONSTITUTION:When beta rays are incident to a metallic body, the beta rays are scattered in the metallic body and travel backward in the direction opposite to the incidence direction. When the metallic body consists of two layers and the upper layer is very thin, the intensity I of the scattered-back rays is as shown by an equation (where Is1 and Is2 are saturation values from the scattered rays from the thin upper layer and thick lower layer, d1 is the thickness of the upper layer, and mu2 is the coefficient of absorption of the material of the lower layer). When the thickness of the metallic foil of the laminate plate 4 is measured, the lower-side metallic foil 3b is brought into contact with the metallic foil 5 of the same material which has a >=100mum and is saturated with the scattered rays and the top surface of the upper-side metallic foil 3a to be measured is irradiated with the beta rays. Then, the scattered rays are incident to the Geiger-tube 7 of a radiation Geiger counter and the dosage of the beta rays is measured. The thickness d1 is calculated on the basis of the dosage from the expression.

Title: Information recording medium
Inventor: UMEDA TOSHIKAZU
IPC: G11B7/24
Filed: 1982-08-31
Abstract: PURPOSE:To facilitate easy production of an information recording medium with a long tracking enable section and a small change of reflected light quantity due to the change in size of a pre-group, by having at least a sloping surface in the cross section of the pre-group and furthermore forming preferably said section into a curved line. CONSTITUTION:A pre-group 20 having a regular and continuous curved line for its section is provided on a single side of a transparent resin substrate 9. It is preferably to have a Gauss type and approximate shape for the pre-group 20, and a sine type or a sloping surface. The tracking enable section A can be increased up to a length equal to a track space although the position of the group 20 or a recorded part 12 is shifted owing to a curved line section to produce a shift to the spot position as shown by double dot chain lines since the spot position still covers the group 20. Then a range to obtain a tracking error signal can be increased by the depth of the group 20. This ensures correct reproduction and tracking. The reduction of the reflected light quantity in a tracking error state is small than a rectangular group. The molding defects generated in a press process are reduced, and it is easy to obtain a surface form corresponding to the intensity distribution of laser light.

Abstract: PURPOSE:To improve close contactness by providing resist and a film which is inferior in close contactness on a substrate, immersing them into an organic solvent and then drying them with fleon vapor. CONSTITUTION:A PSG film is formed on a substrate and it is then immersed into isopropylalcohol liquid. The substrate is housed within a carrier 9 in a stainless steel case 1, the fleon gas is circulated therein, thereby the substrate is dried. This processing replaces the water absorbed at the PSG surface with the isopropyl group, unused solution is replaced with the fleon vapor and remaining fleon is exhausted from the case and is separated by vaporization. Thereby, affinity with resist which is an organic substance becomes strong, improving close contactness. Such substantial improvement in close contactness is held for a long period while the organic group at the surface is not separated, providing much contribution to improvement in quality at the succeeding semiconductor production processes.
