Title: Light reduction type smoke sensor
Inventor: HARANO SHIGETO
IPC: G01N21/27
Filed: 1980-07-15
Abstract: PURPOSE:To sense the constant light reduction with regard to the increase in smoke concentration at all times, by periodically rewriting transmission data in a mechanical latching memory when volatile memory of smoke is absent, compensating contamination and the like in optical system caused by the continuous use for long time. CONSTITUTION:Smoke transmission degree I and transmission degree I0 without smoke are digitally processed in an A/D converter 25, and given to the volatile memory 28 via a switch 26. The I0 data which is stored in the volatile memory 28 is always stored in the mechanical latching memory 27 as information. In this constitution, the data in the volatile memory disapears at the time of electric power failure. When the power is restored, coefficient of light reduction can be readily obtained, with the information in the mechanical latching memory 27 as I0. Thus the constant light reduction can be always sensed even after the power is restored.

Title: Feeding device for cut piece of header
Inventor: OZAWA SHINJI
IPC: B21K27/06
Filed: 1988-04-19
Abstract: PURPOSE:To extend the life of a die and to prevent a defect generation by pivotally fitting an opening and closing plate to a perforated stationary cutting die and the cutter holder of a movable cutter and providing a supporting body freely movably. CONSTITUTION:A wire rod 23 is passed through the hole of a cutting die 24 by a wire rod feeding device and stopped at the parallel face of a recessed cutter 16 in semiconductor shape. Simultaneously with cutting the wire rod 23 by advancing the cutter arm 14 linked to a header a cut piece 22 is interposed between the semicircular recessed cutter 16 and a supporting body 20 with the pressing of the spring 21 of the supporting body 20 whose opening and closing and adjusted by a stopper 25 in advance and stopped by transferring it to a forming die 26. When the cut piece 22 is started to be inserted to the forming die 26 by a 1st punch pin then, the opening and closing plate 18 connected to the header releases the supporting body 20 by its pressing. When the cutter arm 14 is retreated, it returns prior to the initial operation start. The supporting body 20 thus prevents the breakdown of the forming die 26 without hanging on the cut piece 22, etc., and can extend the life of the die.

Title: Continuous manufacture of sic
Inventor: SAWAMURA KENTAROU
IPC: C01B31/36
Filed: 1979-07-31
Abstract: PURPOSE: To enhance the thermal efficiency of a method of continuously manufacturing SiC by using carbon in excess in starting material and heating the starting material by directly supplying an electric current to widely disperse the current in the material.  
     CONSTITUTION: Starting material is prepared by mixing silica or silica-carbon moldings into carbon fine grains. For example, starting material 10 prepared by mixing silica sand and graphite powder in an SiO 2  to C ratio of 1:6 is fed into the vertical type furnace from hopper 6. An electric current is supplied to material 10 from upper and lower electrodes 2 to generae resistance heat, and the internal temp. of the furnace is controlled with graphite pipes 8 so that the temp. becomes about 1,700°C at the central part. Thus, SiC is formed and since material 10 contains C in excess, little silica is left. The average load of the electric current is about 310kW. The resulting SiC and unreacted material are continuously taken out of the furnace bottom. The reaction product contains about 53% SiC.

The width of the upper side pry 7a is made smaller than that of the lower side pry 7b. Cusion rubber 70, which is 40 deg.-75 deg. in JIS hardness and the thickness of which reduces toward the both ends, is arranged between the both ends of the both prys 7a and 7b in order to absorb or alleviate the strain occurring at the end of the pry. In addition, a middle belt layer 11 having the cord angle of 10 deg.-40 deg. is placed at the outside of the breaker 7 along the middle line of the rubber thickness, while side belt layers 12a each having the cord angle of 0 deg.-10 deg. are placed on the both sides of the middle belt layer 11, being neighbored on the upper side pry 7a. With this constitution, durability, road gripping performance, and running performance of the tire at the time of high speed running can be enhanced.

Title: Fuel injection valve
Inventor: ITO EIJI
IPC: F02M61/18
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of suppressing the uneven abrasion of a valve part formed of a valve member and a valve seat and constantly holding the lift quantity of the valve member. SOLUTION: Since a needle valve 20 is supported by a valve body 11 in such a manner as to be capable of reciprocating and rotating in a first slide part 22 and second slide part 25 axially isolated, a contact part 21 is hardly shifted radially in the reciprocating of the needle valve 20. Since a plurality of grooves 23 are formed on the circumferential wall of the first slide part 22 in the direction orthogonal to the axial center of the needle valve 20, the needle valve 20 is rotated by the fuel passing the grooves 23 in fuel injection to change the circumferential position of the contact part 21 in seating. Therefore, the uneven abrasion of the contact part 21 and the valve seat 11a can be prevented.  Further, since the needle valve 20 is engagingly locked by a spacer 12 in lifting, the lift quantity of the needle valve 20 is never changed even if the sliding part between a protruding part 26 and a spring seat 27 is worn by the rotation of the needle valve 20.

Filed: 1989-04-19
Abstract: PURPOSE:To enhance durability, to stabilize chargeability, and to obtain a sharp image free from fog by disintegrating a charge controller and the developing toner and specifying volume average particle diameters of them. CONSTITUTION:After the charge controller is synthesized, too large particles, such as agglomerates, are disintegrated by a disintegrator or cut off by air elutriation and the like. The volume average particle diameter A of the charge controller and the volume average particle diameter B of the toner are regulated so as to satisfy the following expressions: 5mum<=B<=20mum and A<=0.3XB. If A exceeds 0.3XB, the dispersion of the charge controller is deteriorated, causing segregation and it is preferred to regulate the content of >=12.7mum particles of the charge controller to <=1.0wt.%, and if >1.0wt.%, it causes also poor dispersion and segregation.
