Title: Fire detector
Inventor: YAMAMOTO SHINTARO
IPC: A62C31/00
Filed: 1990-02-23
Abstract: PURPOSE:To make it possible to detect the generation of a fire in a wide detection area by using an circular scanning optical system as a scanning optical system for scanning the visual field of an infrared ray detecting element and constituting the optical system so that the visual field of the detecting element is included on a scanning axis. CONSTITUTION:The fire detector has the infrared ray detecting element 2, the circular scanning optical system 1 for circularly scanning the visual field of the element 2 and a judging part 5 for judging a fire generation direction based on the scanning direction of the system 1. The system 1 is constructed so that a member for interrupting a visual field is not arranged under a mirror M1 for scanning the visual field. Since the system 1 is used for scanning the visual field of the element 2, frames due to fire generation can be detected in the wide detection area by the simple and inexpensive constitution.

Title: Molded transformer for outdoor use
Inventor: NAGATOMO SUMI
IPC: H01F27/02
Filed: 1994-03-15
Abstract: PURPOSE:To prevent peeling between a case and a mold resin and the genera tion of air bubbles in the mold resin to insure against the possibility of partial discharge which accelerates the deterioration of insulation. CONSTITUTION:A plurality of injection tubes 8, the top of which exceeds the height of the contents 20 of a mold transformer with its bottom reaching the bottom of a case 1, are installed near the wall inside the case 1. By injecting an epoxy resin 52 from the top of the injection tubes 8, the epoxy resin fills gaps in quartz sand, which has been charged beforehand, from the bottom up, so that air will not collect during the process and no air bubbles will remain. Also, by arranging a strip-shape, conductive elastic sheet 9 in contact with the inside of the case 1, temperature change during the operation of the mold transformer may expand or shrink the mold resin 5, but its dimensional change is absorbed by the elastic sheet 9. As a result, no gaps will occur between the elastic sheet 9 and the mold resin 5 and between the elastic sheet 9 and the case 1.

Title: Substrate potential generation circuit
Inventor: KATANOSAKA TADAO
IPC: G11C11/408
Filed: 1990-02-23
Abstract: PURPOSE:To supply a stable substrate current and to stabilize an operation by a method wherein a control circuit which makes a capacitance small when a substrate potential is shallow and which makes the capacitance large when it is deep is installed at a capacitance part of a ring oscillator. CONSTITUTION:When a substrate potential VSUB is sufficiently low, an n-MOS Q1K becomes conductive, the L-level appears at an nodal point N11, a nodal point N12 is set to the H-level and N-MOS's Q1F to Q1H are set to an ON state. As a result, the capacitance at the individual nodal points has values equal to the same of C11 and C15, C12 and C16 and C13 and C17 respectively; the current supply capacity of a substrate-potential generation circuit can be suppressed low. Then, when a power-supply potential VCC becomes high, an ISUB is increased, the VSUB becomes shallow and the n-MOS Q1K is turned off. As a result, the nodal point N11 is set to the H-level and the nodal point N12 is set to the L-level. Consequently, the capacitors C15 to C17 are cut off, and the oscillation frequency of a ring oscillator becomes high. As a result, the current supply of the substrate-potential generation circuit is increased. That is to say, it is settled down to the VSUB whose potential is deep as compared with a case where the oscillation frequency is low.

Title: Measuring method for characteristics of epitaxial semiconductor wafer
Inventor: MOURI MIKIO
IPC: H01L21/66
Filed: 1981-03-25
Abstract: PURPOSE:To improve the reliability by measuring a specific resistance at an epitaxial layer grown on an unformed part having no buried diffused layer formed on a substrate, thereby enabling stable measurements. CONSTITUTION:When a buried and diffused region 2 is formed in a substrate 1, the region 2 is not selectively formed only at one position in size corresponding to one device of an integrated circuit device forming portion and retained, an epitaxial layer 3 is formed on the substrate 1, and an epitaxial wafer 7' is formed. The specific resistance of the layer 3 of the wafer 7' is measured by contacting four probes a, b, c, d with the center on the surface of the layer 3' formed on the unformed part m. Thus, since no buried and diffused region 2 is presented under the four probes, the measurement can be always performed under the constant conditions, thereby enabling a measurement with less error.

Title: Apparatus for controlling vane type variable displacement pump
Inventor: IDETA YASUFUMI
IPC: F04C14/22
Filed: 1982-03-23
Abstract: PURPOSE:To omit a hydraulic cylinder, by employing such an arrangement that both of the confined sections on the suction side and on the discharge side are communicated with each other directly when the line pressure is lower than the set pressure of a regulator valve and a cam ring is moved to a most displaced position by a spring. CONSTITUTION:When the speed of rotation of a rotor 24 is low and the line pressure is lower than the set pressure of a regulator valve 31, oil passages 33 and 34 are communicated with each other by the regulator valve 31, so that the hydraulic pressure in a confined section 32 on the discharge side is introduced into a confined section 35 on the suction side. Resultantly, the hydraulic pressure in the section 32 and that in the section 35 become equal to each other, so that no force due to the hydraulic pressure is acted to a cam ring 21. Therefore, the cam ring 21 pushed to the most displaced position by the force of a spring 25 and the discharge volume is increased. By employing such an arrangement, it is enabled to omit a hydraulic cylinder that has been required for oscillating the cam ring 21 and to reduce the size of a control apparatus for a pump.

Abstract: PURPOSE: To form cellulose gel particles suitable as a filter medium used in, for example, gel filtration, by adding a coagulant, under agitation, to a dispersion containing dispersed drops of a cellulose solution and thereby coagulating the drops into gel.  
     CONSTITUTION: 1pt.wt. cellulose (e.g., regenerated cellulose) is mixed, under agitation, with about 15W50pts.wt. dimethyl solfoxide (DMSO) and about 0.8W 10pts.wt. paraformaldehyde at about 80W130°C. The resulting cellulose solution is dispersed in a dispersion medium (e.g., liquid unreactive with the cellulose solution and immiscible with DMSO, e.g., liquid paraffin). Then, a coagulant (e.g., ethyl acetate, dimethyl-dichlorosilane) is added, under agitation, to the above-produced dispersion to coagulate the drops of the cellulose solution. If necessary, the regeneration of the cellulose is brought to completion by use of hot water, about 50W95°C and then the coagulated particles are separated and washed to obtain cellulose gel particles.
