Title: Insulating mat for curved surface
Inventor: KURAUSU ROOTO
IPC: F16L59/02
Filed: 1989-02-20
Abstract: PURPOSE: To guarantee the deflecting property of an insulating mat while its compression force is increased by interposing a brace strip having a high compression strength in the direction perpendicular to a carrier web between strips made of mineral fiber material. CONSTITUTION: A insulating mat 1 is formed from a carrier web 2 in the form of aluminum meshing film and an insulating layer 3, and the insulating layer 3 is composed of strips 4 made of mineral fiber and a brace strip 7 interposed between the strips 4 perpendicularly to the carrier web 2 and made of asbestos fibers 8 having a high compression strength. Thereby a softness to comply with the requisite deflection of the mat 1 can be secured while the compression force of the mat 1 is increased substantially.

IPC: G03G15/05
Filed: 1979-03-31
Abstract: PURPOSE:To prevent the degradation in image quality with a simple constitution by changing the air state of the spacing between the pin electrodes for forming dot images and a dielectric recording drum thereby making the discharging easy and sure. CONSTITUTION:When the exhaust air of high temperature and high humidity by a fan 14 from a fixing device 9 is injected from a nozzle 12, the air state of the spacing between the pin electrodes 3... for image forming and a dielectric recording drum becomes high in temperature and humidity and becomes easy to cause discharge. Hence, the spot images by discharge are evenly and well formed on the dielectric recording drum without requiring intricate mechanisms such as evening of the thickness of the dielectric layer of the dielectric recording drum, evening of plural electrodes 3... and evening of the air spacing, and the degradation in image quality is prevented by the simple constitution.

Title: Optical type defect inspection equipment
Inventor: UTSU YOSHINORI
IPC: G01B11/30
Filed: 1985-02-27
Abstract: PURPOSE:To achieve a higher detection accuracy of defects, by converting the light from a scanning position of an object to be inspected into an electrical signal with a uniform sensitivity. CONSTITUTION:A photo electric multiplier tube 67 is provided at one end of a photoconductive rod 55 and the light propagated therethrough 55 is converted into an electrical signal to be amplified 68 and led outside. A reflecting mirror 69 is provided at the other end thereof as opposed thereto to reflect light reaching the mirror 69 to the element 67. In such an arrangement, light entering a case 51 through a slit 52, light at light receiving points by light beam scanning over an object to be inspected is diffused with a diffusion plate 54 to be incident into the photoconductive rod 55 at angles, showing a tendency that the incident light at the position close to the element 67 is higher in the sensitivity. So, the position of the diffusion plate 54 is adjusted with the photoconductive rod 55 to increase the interval between the diffusion plate 54 and the photoconductive rod 55 at a part close to the element 67. In this manner, a higher defect detection accuracy can be achieved by adjusting the light at any incident position along the length of a slit 52 to be the same in the sensitivity.

Filed: 1995-02-27
Abstract: PURPOSE: To evaluate the activity of catalyst by observing the alumina particles for carrying the catalyst directly through an electronic microscope with magnification of 200000 or above. CONSTITUTION: While heating an insulating porous body coated with no conductor on the surface thereof at 400-800 deg.C, preferably at 500-700 deg.C, in order to prevent the charge-up thereof, the surface of the porous body is observed by means of an in-lens FE-SEM (Scanning Electron Microscope) with magnification of 200000 or above under acceleration voltage of 15-20kV. Even if the surface of the porous body is not coated previously with a conductor, charge-up phenomenon does not take place during observation under acceleration voltage in the range of 15-20kV. When alumina for carrying catalyst is evaluated, for example, the size, shape and aggregation of alumina primary particles or the distribution of pores can be observed directly and nondestructively with magnification of 200000 or above. The inventive method is useful for evaluating the activity of catalyst.

IPC: G11B25/04
Filed: 1990-02-20
Abstract: PURPOSE:To precisely read the data of a magnetic disk by decreasing gradually the plate thickness of each arm to constitute an arm group from a bottom toward a top. CONSTITUTION:The arm group is constituted by decreasing gradually the plate thickness of each arm 1 to constitute it from the bottom toward the top, and flexible printed wire boards (FPC) 2 jointed to each arm 1 are formed altogether into the same plate thickness. Therefore, by setting properly the plate thickness (t) of the arm 3, thermal deformation quantity to correct ¦DELTALA-DELTALS¦ can be given to the fitting part of a magnetic head 1 of the arm 3 at optional height L from a reference plane of a base stand 4. Accordingly, the larger the plate thickness of the arm 3 is, the larger linear expansion is, and a bimetal effect with the FPC 2 is canceled, and the curvature of the arm 3 becomes small, and the higher the arm 3 is positioned, the larger its curvature is, and the larger correction can be done. Thus, the data of the magnetic disk can be read precisely.

Abstract: PROBLEM TO BE SOLVED: To provide a clothes drier which enables good drying operation without infinitely continuing temperature control. SOLUTION: A thermostat switches off during a drying operation by temperature control, and then, if the thermostat remains off for ten seconds, a thermostat-off counter for counting the number of times that the thermostat switches off from on is incremented to '1' (a step S25). After that, a state of the thermostat is repeatedly checked until the thermostat-off counter becomes '2', or it is determined in a step S11 that the drying operation by temperature control is completed. When the switching of thermostat from on to off is re- detected, and after that, the thermostat is off for ten seconds, the thermostat-off counter is incremented to '2', and the drying operation by temperature control is completed.

Title: Electrochemical detector
Inventor: SHIMIZU MASATO
IPC: G01N27/28
Filed: 1986-02-25
Abstract: PURPOSE:To enable the prevention of the generation of bubbles in a measuring chamber while keeping a sample in a liquid to be measured from diffusion, by sandwitching a pressurizing section having a through hole with a small inner diameter between an electrode section and a reference section so as to cause a pressure loss of the liquid being measured at the pressurizing section. CONSTITUTION:A pressurizing section 11 is provided between an indication pole 2a and an opposed pole 2b and a reference pole 4. When introduced from an introduction pipe 9a, a liquid to be measured is led into the pressurizing section 11 via the indication pole 2a the opposed pole 2b and then, discharged through a lead-out pipe 9b via a liquid junction 12. With the inner diameter of the pressurizing section 11 noticeably noticeably smaller than that of the indication electrode 2a and the opposed electrode 2b, a piping resistance is generated, which pressurizes the liquid being measured through the indication electrode 2a and the opposed electrode 2b making it hard to generate bubbles in the liquid being measured. Moreover, as the inner diameter of the liquid junction 12 is larger than that of the pressurizing section 11, there will be a less pressure of the liquid being measured passing through the liquid junction 12. The liquid being measured will not reverse to an internal liquid 13 through the liquid junction 12 to obtain assuring a stable reference potential. This can prevent the generation of bubbles in the measuring chamber thereby in noway disturbing a plug flow of the liquid being measured.
