Title: Focal plane shutter of blade type
Inventor: MASUDA KAZUFUMI
IPC: G03B9/36
Filed: 1978-07-04
Abstract: PURPOSE: To surely prevent light leakage simply through application of simple additional fabrication by bending one of plural plades at one or more places and letting the blades make close contact with each other.  
     CONSTITUTION: Bends 1-7a thru 1-10a are formed to each of the other four blades 1-7 thru 1-10 except the blade 6 to be pivotally fitted to the position in close contact with an arm 32, out of 5 shutter blades. The bending angles of these bends vary with the thicknesses of the blanks of the blades and other conditions and the shapes of the respective bends are not always parallel to the straight line F. Application of bends to each of the other blades except the blade 6 in this way enables the gaps of the overlap portions of the respective blades to be eliminated and enables light leakage to be surely removed.

Title: Production of metallic lithium powder
Inventor: MATAKE SHIGERU
IPC: B22F9/30
Filed: 1982-05-17
Abstract: PURPOSE:To enable the simple production of metallic Li powder having optional grain sizes at a proper time by heating Li3N powder in an inert gaseous atmosphere or under reduced pressure and decomposing the same thermally while preventing melt sticking. CONSTITUTION:Li3N powder 1 is dropped from the upper part of a quartz tube 2 and the falling Li3N powder is decomposed thermally by a heater consisting of an iodine electric lamp 4 for heating and is immediately cooled to deposit metallic Li powder 5 on a well part. An inert gas 6 is flowed from the lower part to the upper part of the tube 2 in this case to control the speed of dropping. The Li3N powder 1 to be used is controlled to have the grain sizes similar to the grain sizes of desired metallic Li powder. On the other hand, the Li3N powder is spread thinly and is placed on a tray to prevent the melt sticking thereof in the stage of thermal decomposition under reduced pressure.

IPC: G02B6/24
Filed: 1980-06-17
Abstract: PURPOSE:To automatically perform initial position setting work of optical fibers by constituting a pair of mutually opposing holders of the turnable slip bases of which the top surfaces are formed into an arc shape and turnable rollers for pressurizing which press the optical fibers onto said top surfaces. CONSTITUTION:Exposed optical fibers are set respectively in slip holders 3, 4, and at this time, these are beforehand so located that the distances between the leading ends of both exposed parts and a butt bar 65 are smaller than the extents of movements of slip bases 12, 12a. In the state that the exposed parts oppose to each other, the optical fibers are pressed onto the slip bases 12, 12a by pressure rollers 13, 13a, after which a butt bar solenoid 66 is energized. By this, the bar 65 is forced upward. Thence, when rotary solenoids 30, 31 are energized, the slip bases 12, 12a turn and approach each other, and the end parts of the optical fiber exposed parts hold the top end part of the butt bar therebetween. Thereafter, the solenoid 66 is deenergized, and the bar 65 is pulled down, whereby the initial position is set.

Title: Polyquinone derivative, method for synthesizing the same and method for using the same
Inventor: YAMAMOTO RYUICHI
IPC: C08G61/12
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a polyquinone derivative having a polycyclic quinone being a conductive polymer containing a quinone skeleton as the polymer chain, a method for producing the same and an electrochromic element material and an n-type device material utilizing the same. SOLUTION: A polyquinone derivative having a substituent bonded through an element of group 15 or 16 has a molecular weight of 1,000 or above and shows the function of conductivity, electrochromism or the like. In virtue of the polycyclic structure of the substituent and the quinone, this derivative easily forms carrier species without oxidation and reduction and easily develops conductivity. It is estimated that the formation of the carrier species is ascribable to various resonance structures. An example of the potent process for producing the polyquinone derivative consists of incorporating divalent groups derived from halogens from the corresponding quinone dihalogenide compound in the chain of the polymer by using the reactivity of the halogens.

Abstract: PURPOSE: To obtain correct welding conditions with ease by so constituting the welder that wire feed speeds and welder output voltages are increased or decreased according to the components of shielding gas.  
     CONSTITUTION: A wire feed motor M is driven at the speed corresponding to the voltage being the sum of the output voltage e 1  of a welding voltage detector 1 and the output voltage e 2  of an auxiliary circuit 2. Hence, a dial scale which indicates  the components of the shielding gases used is attached in correspondence to the set  position of the variable resistor 20 of an auxiliary circuit 2. If the variable resistor  R20 is set to meet the componets of the shielding gas to be used, the wire feed  speed, i.e., welding current, of always a correct condition range may be obatained.  To set with the dial scale of the variable resistor R20 in the case of using, e. g.,  CO 2  and Ar, only required is to set the position where the output e 2  of the auxiliary  circuit 2 becomes minimum at CO 2  100% and the position where e 2  becomes  maximum at Ar 100%.

Title: Driving mechanism of tape recorder
Inventor: SUGIHARA MASANORI
IPC: G11B15/44
Filed: 1980-06-20
Abstract: PURPOSE:To reduce a load on a motor at the beginning of a reversed rotation by applying excessive tensile force to a tape by reversing the rocker arm of a fast- forward and rewinding driving mechanism at a slight interval of time when the  rocker arm is switched from one reel turntable to the other. CONSTITUTION:A projection washer 27a presses a projection 21c with its flank. Consequently, this projection washer 27a does not meet the projection 21c in reversing unless it turns by nearly 360 degrees, so this time lag results in that a tape is extended normally and never damaged. To extend the time lag, washers 27b and 27c are stacked together; the washer 27b turns once to press the washer 27c with its projection 27b', and then two washers turn once in one body to bring a washer 27c  into contact with the projection 21c.
