Title: Cartridge for recording medium
Inventor: KOYAHARA SATORU
IPC: G11B7/24097
Filed: 1988-04-26
Abstract: PURPOSE:To easily manage the recording medium housed in the title cartridge against an environmental change by providing a recording means and detecting a change in outside environment which affects the recording medium housed in the cartridge. CONSTITUTION:This cartridge 2 for recording medium houses an optical disk 3 as the recording medium. A pressure sensitive history recording sheet 5 is produced in such a way that micro-capsules containing a pigment precursor are uniformly applied on the surface of a sheet-like body and a solid-state acid is further applied on the surface of the applied layer. Therefore, when pressure higher than a prescribed level is applied to a certain part of the sheet 5, the micro-capsules are destroyed and the pigment precursor is brought into contact with the solid-state acid and forms a color, resulting in a discolored zone 5A. Therefore, the magnitude of the force applied to this cartridge 2 can be discriminated when the discolored zone 5A is observed.

Filed: 1987-04-24
Abstract: PURPOSE:To obtain high-quality terephthalic acid for direct polymerization, by specifying spectral reflectivity of terephthalic acid crystal in a slurry containing terephthalic acid produced by liquid phase air oxidation of paraxylene when the slurry is successively subjected to additional oxidation. CONSTITUTION:para-Xylene is oxidized (1) in an amount of >=95% of the above- mentioned raw material to terephthalic acid in acetic acid solvent in the presence of a catalyst consisting of a heavy metal and bromine at 180-230 deg.C using molecular oxygen and as necessary subjected to low-temperature additional oxidation (2) at a temperature lower than the above-mentioned temperature to afford slurry containing terephthalic acid particle having >=0.92 reflectivity ratio expressed by the formula. Then the slurry is subjected to high-temperature additional oxidation (5) at 235-290 deg.C with molecular oxygen and then the resultant terephthalic acid is recovered (7) by crystallization (6, 6', 6''). Thus high-quality terephthalic acid providing excellent polymer whiteness when polyester is produced by directly reacting the recovered terephthalic acid with a glycol component is stably obtained in an industrial scale.

Filed: 1984-05-19
Abstract: PURPOSE:To eliminate the adverse influence of a handling apparatus to a measurement by electrically insulating a holder composed of a conductor from a housing of the apparatus, mounting it, and electrically connecting the holder with a measuring unit. CONSTITUTION:A portion 5 for holding a semiconductor device 1 is composed of a conductor, and an electrode rod 6 is implanted to a test head 3. The holder 5 is mounted through an insulator 7 at a housing 8 of a handling apparatus. Accordingly, when the device 1 is inserted into a contact 4, the holder 5 is contacted with the rod 6, and electrically connected so that the head 3 of the measuring unit becomes the same potential as the holder 5. Thus, a mechanism for holding the device 1 operates as the handling apparatus, but the holder 5 electrically operates as one portion of the measuring unit. Particularly, when the periphery of the device 1 is surrounded by a conductor, an electrically shielding effect is obtained to prevent a defect signal from the handling apparatus.

Abstract: PURPOSE:To simply block the advance of a shaft being rotated by inertia at the rear end of a tube by forming the hooking groove of a pinion shaft inserted with a centrifugal weight at a tube support bearing inner periphery position and a position apart from a tube rear end when the shaft is located at the retreat position. CONSTITUTION:The centrifugal weight hooking groove 24 of a pinion shaft 11 is formed at a position apart from the rear end of an inner tube 18 and the inner periphery position of the support bearing 19 of the tube 18 when the shaft 11 is located at the retreat position. The pinion 13 of the shaft 11 is advanced and engaged with a ring gear 17, when a switch is turned on, the shaft 11 is rotated, and an engine is started. The shaft 11 is not rotated during the advance, thus a centrifugal weight 251 in the hooking groove 24 is located at the storage position. When the shaft 11 is retreated after a start, the centrifugal weight 251 is released from the rear end face of the inner tube 18 and expanded in the radial direction by the inertial rotation, it is restricted by the inner diameter of the support bearing 19 of the tube 18, and the re-advance is blocked at the tube rear end face.

Title: Method for suppressing gaseous nox by hydrogen peroxide
Inventor: SHIMOMURA TADASHI
IPC: G01N27/42
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to automatically control the generation amount of gas corresponding to a current value by electrolyzing a nitric acid-containing liquid, such as a stainless steel pickling liquid containing hydrofluoric acid, at a specified potential and regulating the addition amount of the hydrogen peroxide to oxidize NOx to nitric acid in accordance with this electrolytic current value. SOLUTION: The nitric acid-containing liquid, for example, nitric acid-containing liquid 2 of a stainless steel pickling bath 1 consisting of mixed acids containing, for example, nitric acid and hydrofluoric acid is electrolyzed with a specified voltage via a three electrode type voltage controller 6 having a platinum electrode 4 and a reference electrode 5. The electrolytic current value having a proportional relation with the generation amount of the gaseous NOx of the nitric acid-containing liquid 2 is then detected. A supply pump drive control signal 8 is transmitted from the voltage controller 6 to a hydrogen peroxide supply pump 3 to add a prescribed amount of hydrogen peroxide to the pickling bath 1.  As a result, the NOx formed in the nitric acid-containing liquid 2 is oxidized as the nitric acid and the generation amount thereof is automatically maintained at a prescribed level and the excessive consumption of hydrogen peroxide can be prevented.

Title: Heat transfer pipe
Inventor: YUMIKURA TSUNEO
IPC: F28F13/12
Filed: 1978-08-21
Abstract: PURPOSE:To obtain this heat transfer pipe that can gain the best heat exchange efficiency all the time to the change of flow rate in the pipe, its manufacture is easy and is cheap, by loosely fitting a coil spring, which one end is fixed to a pipe guiding a heat transfer fluid, to the pipe guiding the fluid. CONSTITUTION:This heat transfer pipe is formed by a cylindrical pipe 1, a cylindrical coil spring 2 loosely fitted to the inside and a fixing piece 3, which is mounted to an inwall of the cylindrical pipe 1 and fixes one end of said coil spring 2. Thus, heat exchange efficiency is improved because fluids flowing in the cylindrical pipe 1 are turned into turbulent streams along a spiral shape of the cylindrical coil spring 2. The cylindrical coil spring 2 expands and contracts in response to the magnitude of the kinetic energy of the fluids, and the pitch settles down to one that the best heat exchange efficinecy is obtained to flow rate. Said coil spring may be disposed at the outside of the pipe, and may be formed in a cylindrical or a conical shape.

Filed: 1980-07-24
Abstract: PURPOSE:To sort normal and defective products accurately at all times by calculating the mean value of bodies to be metered successively, and by making automatic corrections so that a reference value stored in a sorting machine is equal to the mean value at all times. CONSTITUTION:The reference weight value of bodies to be metered is stored in a register previously and then compared by a comparator with a weight signal from a metering part to judge their propriety. In this case, the output of the comparator is utilized to correct the said reference value successively. For example, the upper- and lower-limit deviation values and reference value of a body 20 to be metered are set by a setter 13, and their results of arithmetic processing are compared by a comparator 12 with a metering part to determine the propriety. In this case, adequate signal intensity and a measured value are returned to registers 2 and 3 at the same time to find the mean values by an operator 4, and a new deviation value and reference value are sent to the comparator 12 via a register 6, etc., to correct the reference value automatically. This method makes accurate the propriety decision on a hydroscopic product, etc.
