Title: Regenerating method of used tire
Inventor: KURUTO EDORAA
IPC: B29K21/00
Filed: 1995-04-21
Abstract: PURPOSE: To regenerate a used tire economically by preventing the introduction of air between a tire and a treat to be added newly and strengthening adhesion by a method in which a rubber binder between a running tread and a tire is vulcanized and adhered to the tire. CONSTITUTION: A running tread 1 to be formed to regenerate a used, abraded tire is formed as a closed ring, forms a profile tread on the outside of it by a plurality of tread protrusions 11, and has channels which cross each other on its inside and formed in the shape of a web. In a tire 2 to be fitted to a wheel 4, a rubber binder layer 3 is mounted on the abraded, roughened surface of the tire 2, Since the layer 3 is spread and formed in the tire 2, air pockets are avoided. In the running tread 1, a through opening 14 connected to the channels 12 of the inside surface is formed.

Title: Magnetic recording tape
Inventor: USUKI KAZUYUKI
IPC: G11B5/64
Filed: 1995-04-21
Abstract: PURPOSE: To obtain a magnetic recording tape capable of inhibiting the corrosion of the magnetic film by forming a back coating layer of >=pH5.7 contg. a compd. having prescribed characteristics. CONSTITUTION: A magnetic film consisting essentially of ferromagnetic powder and a resin binder is formed on one side of a nonmagnetic substrate and a back coating layer is formed on the other side to obtain the objective magnetic recording tape. The back coating layer has >=pH5.7, contains 20-80wt.% carbon black basing on the amt. of nonmagnetic powder and further contains ester produced from carboxylic acid and alcohol as a compd. having an unsatd. bond and an F atom in each molecule. The magnetic recording tape is wound on a hub and housed in a resin vessel to produce a magnetic recording cassette. Since the specified F-contg. compd. is contained as a lubricant, even when a resin binder generating corrosive gas such as NO2 or HCl is used, the corrosion of the magnetic film is effectively inhibited at the time of storage in an environment at high temp. and humidity.

Abstract: PURPOSE: To secure the quick and accurate measurement for a large amount of samples by ensuring an automatic supply of the sample to each measuring device when various types of physical properties are measured for the cigarette or the cigarette filter.  
     CONSTITUTION: The measuring device consists of weight measuring instrument 3a, ventilation resistance measuring instrument 3b, diameter measuring instrument 3c, length measuring instrument 3d, hardness measuring instrument 3e and the sample feed mechanism. The samples supplied sequentially from hopper 8 are sent one by one to grooves 2aW2e by the up and down movement of feed tooth 6. Then each measurement is carried out simultaneously via instruments 3aW3e. After the measurement, the samples at instruments 3b and 3c are returned to grooves 2b and 2c, and then tooth 6 is actuated to move the samples into the next groove. The samples put newly into grooves 2b and 2c are pushed into instruments 3b and 3c, and thus all instruments are ready for start to repeat the measurement. In such way, a large amount of samples can be measured in a quick and automatical way.

Title: Photoelectronic device
Inventor: AIKI KUNIO
IPC: G02B6/42
Filed: 1986-05-26
Abstract: PURPOSE:To perform stable optical communication even if temperature variation takes place, by extending the optical fiber between a fiber guide and positioning and fixing body in a curved state. CONSTITUTION:The optical fiber 16 between a fiber guide 4 fitted to one end of a package main body 7 and the positioning and fixing body 17 of a sub- carrier 11 is extended in a gently curved state. Therefore, no repetitive stress is applied to the optical fiber and the solder fixing the optical fiber and no buckling takes place in the fiber and the solder is not fatigued, even if the two fixing sections fixing the optical fiber and the base sections supporting the fixing sections are made of a metal having a coefficient of thermal expansion which is far higher than that of the optical fiber and the distance between the two fixing points varies due to thermal contraction or thermal expansion, because the optical fiber between the two fixing points can cope with the change in distance by means of the curved section. Therefore, stable optical communication an be continued even if the temperature varies.

Zr. CONSTITUTION:A hollow barrier cylinder 13 is placed in a graphite crucible 11 and molten pure copper 19 in a melting furnace 18 is fed into the crucible 11. Granules 4 of a Cu-Zr mother alloy consisting of 1-89wt.% Zr and the balance Cu are put in the molten copper 19 in a feed chamber 14 between the crucible 11 and the cylinder 13.

Title: Distance detecting apparatus
Inventor: WAKAMATSU KAZUHIKO
IPC: G01B7/02
Filed: 1980-08-29
Abstract: PURPOSE:To maintain an output voltage constant over a wide temperature range by controlling the conductance of a variable conductance circuit with an amplified output of a minute DC voltage generated due to the temperature change of a detecting head. CONSTITUTION:A minute DC voltage resulting from the change in coil resistance caused by the temperature change in the coil of a detecting head 1 is generated between the terminals of the capacitor of a resistance change detecting circuit 2. This DC voltage is inverted and amplified by a DC voltage amplifier 3 and then, the amplified voltage is applied to the base of the transistor of a variable conductance circuit 4. Consequently, the base current of the transistor decreases and, apparently, the Q-value of a high-frequency circuit including the coil of the detecting head 1 decreases through a change similar to the negative temperature coefficient change. Consequently, the increase in the output voltage of the detecting head 1 is counterbalanced. Therefore, the output voltage of a detecting head can be maintained substantially constant over a wide temperature range, even if the detecting head is very small.

Abstract: PURPOSE:To secure validity by sending data from one disk device to a disk controller, and allowing the other disk device to input read data outputted by the former disk device and compares the input data with its read data. CONSTITUTION:An electronic disk device 3 inhibits a gate 38 from outputting a signal with an output control signal to inhibit even the output operation of a driver 27. Then data is read out of a memory circuit 35 and inputted to a readout buffer 33. Data which is sent from an electronic disk device 2 together with a strobe signal is loaded in a write buffer 32. A control part 31 outputs a data check strobe signal to a comparing circuit 34 unless both a write counter and a readout counter indicate '0', and data in the buffers 32 and 33 are unloaded. When the comparison result indicates mismatching, a circuit 34 outputs a comparison error signal to a control circuit 31 and informs that the electronic disk device 1 has an error with an error information signal in an interface signal group 101.
