Title: Digital input interface circuit
Inventor: FURUHATA MAKOTO
IPC: H03K19/018
Filed: 1984-12-10
Abstract: PURPOSE:To input an external signal to a digital circuit at a high speed with simple circuit constitution by operating a bipolar transistor (TR) which converts the level of the external signal to the input threshold value of the digital circuit while its base is grounded. CONSTITUTION:A signal source Sg outputs a signal whose amplitude corresponds to the level of a current, i.e. current signal. Consequently, the PNP bipolar TRQp operates on common base basis to convert the input signal from the signal source Sg to the input threshold value (about 0-0.7V) of the IIL. The cutoff frequency falpha of the common base TR is much higher than the cutoff frequency fbeta of a common emitter TR and the considerably high cutoff frequency falpha is obtained even by the PNP bipolar TR. Consequently, the maximum frequency of a signal which can be inputted to the IIL is increased greatly as compared with the conventional frequency.

Abstract: PURPOSE:To achieve a longer life of use of a sensor by forming a sensor protection cover from a drawn porous resin film with a specified moisture permeability and thickness to protect the sensor properly under an atmospheric condition of a fine dust, mist, oil or the like. CONSTITUTION:A cover for protecting a sensor section is formed from a drawn porous resin film with a moisture permeability of 1,000-50,000g/m<2> per day and a thickness of upto 100mum. Especially the use of the drawn porous film made of porous polytetrafluoroethylene allows the blocking of permeation of fine dusts or others with a low surface energy and moreover, facilitates the permeation of steam. The sensor can be protected from a liquid having a surface active effect and an organic solvent by forming a thin film made of a perfluorosulfonic acid polymer or other hydrophilic resins. It also can be protected against acetic acid or other corrosive gases by adding CaCO3 or other carbonates and a substance such as activated charcoal to absorb and decompose the corrosive gases, thereby enabling an extended life of the sensor.

Abstract: PURPOSE:To equlize quantities of light at the center and periphery of a visual field, by providing a blocking plate for blocking a part of luminous flux to the center (on the optical axis) of the visual field increased in quantity of light from the periphery thereof. CONSTITUTION:A blocking plate 14 is arranged on the optical axis between lenses 11, 12. When luminous fluxes by the light at the center of a visual field and light having an angle theta to the optical axis at the periphery of the visual field are cobserved at the position between the lens 12 and an image pick-up tube 13, said luminous fluxes come to shapes shown by numerals 17a, 17b, 17c as go to the periphery of the visual field from the center thereof. These luminous fluxes form images at positions 18a, 18b, 18c on the surface of the image pick-up tube 13. the light intensity distribution on the surface of the image pick-up tube is reduced and uniformized by the effect of the blocking plate 14 so that the quantity of light at the center of the visual field becomes equal to the quantity theta of light (relative ratio) at the periphery thereof. This blocking plate 14 is constituted so that the diameter of the outer periphery of the outer circle 14a thereof is same to that of each of the lenses 11, 12 and arranged at the center of the optical axis by connecting a blocking inner circle 14b by a connection part 14c.

Title: Force detecting device
Inventor: TAKAHASHI JUNICHI
IPC: G01L1/16
Filed: 1992-09-29
Abstract: PURPOSE:To eliminate the action of a force except an interatomic force among atoms and to enhance the accuracy of measurement by attaching an electric detection means to a cantilever or a joist. CONSTITUTION:A cantilever 20 is deformed by an electrostatic force between an electrostatic charge on a surface of a specimen and a probe 21. The deformation quantity is detected by means of a piezo resistance 22 of an electric detection means provided at a foot part A to be taken outside via patterns 23 so that a force applied to the probe 21 is measured. The cantilever 20 is made of an insulator material and the probe 21 and the resister 22 are electrically insulated from each other so that a voltage of the probe 21 is not influenced by the change of a voltage of the resister 22. Therefore, the action of an electrostatic force except a force among atoms is not generated between the surface of the specimen and the probe 21, thereby improving the accuracy of measurement.

Title: Tetrafluoroethylene resin composition
Inventor: ITO KAORU
IPC: C08K3/04
Filed: 1987-10-16
Abstract: PURPOSE:To obtain a tetrafluoroethylene resin compsn. whose stretching characteristics are improved, by compounding a granular filler having a specified particle diameter with the tetrafluoroethylene resin. CONSTITUTION:A tetrafluoroethylene resin compsn. comprises a tetrafluoroeth ylene resin and a granular filler whose particles size is 25-45mum. This granular filler is used in such a way that the amt. of compounding in the compsn. is 3-40wt.%. When the amt. of compounding is less than this amt., the effect of adding the filler cannot be exhibited and, on the other band, when it is more than this, e.g., in case of a fibrous filler, the expected effect cannot be obtd. either due to the breakage of the fibrous fillers. As the fillers to be used, lubri cating agents such as graphite, molybdenum disulfide, or carbon fiber for friction and abrasion characteristics, and metal powders such as copper, aluminum or glass beads for high specific gravity, heat transfer and electrical conductivity can be cited. When the particle size of the granular filler is 45mu or larger, the particles function as the starting point of breakage at lower elongation and on the other hand, when it is 25mu or smaller, the secondary aggregation of the particles occurs, which gives rise to the starting point of breakage and also causes breakage at lower elongation.

IPC: F16F1/38
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce deformation of a cylindrical rubber elastic body in a circumferential direction end part of a slit, and improve durability by forming both end surfaces of a circumferential direction in the slit in nearly flat surfaces extending linearly in a diameter direction. SOLUTION: A load of a diameter direction and a load of a twisting direction are inputted between a stem member 12 and an outer cylindrical member 14, in a rubber bush 10. When extension deformation of a diameter direction is generated on a cylindrical rubber elastic body 16 in the vicinity of a circumferential direction end part of a slit 26, the circumferential direction end surface 34 of the slit 26 is formed in a nearly flat surface extending linearly in a diameter direction, and thereby, nearly uniform extension stress is distributed on nearly all surfaces of the circumferential direction end surface 26 of the slit 26. Accordingly, local concentration of the extension stress in the cylindrical rubber elastic body 16 is reduced or avoided.  It is thus possible to prevent generation of cracking and the like on the circumferential direction end surface 34 of the slit 26, and it is also possible to improve durability.

IPC: B22D11/06
Filed: 1984-12-11
Abstract: PURPOSE:To provide a titled device which can prevent the remaining of the solidified matter to be formed at the boundaries between stationary gates and drum surfaces and prevent the injury of drums by attaching corrugated or gear-shaped thin sheet rings to the end faces on the peripheries of the drums. CONSTITUTION:A molten metal 4 is accumulated between the rotating water- cooled drums 1, 1' and the stationary side dams 2, 2' and is passed between the drums 1 and 1', by which the thin sheet 3 is continuously cast. The scraper rings 7 consisting of the same material as the material of the drums 1, 1' are attached to both peripheral ends of the drums 1, 1' in this invention. The solidified matter formed at the boundaries between the drum 1, 1' surfaces and the gate 2, 2' surfaces is therefore bitten by the rugged parts of the tooth or wave shape formed on the peripheral surfaces of the rings 7 and is transferred downward in synchronization with the rings 7 rotating integrally with the drums 1, 1'. Such solidified matter is cast together with the solidified shells formed on the drum 1, 1' surfaces to an ingot 3. Since the ingot is cast without sticking of the solidified matter to the gates 2, 2', the characteristic of the ingot is good and the stable casting is made possible with less injury on the drums 1, 1'.
