Title: Zoom lens system
Inventor: TOKUMARU SHIYOU
IPC: G02B15/177
Filed: 1981-06-30
Abstract: PURPOSE:To compensate the performance of lenses over the whole focal distance by constituting a zoom lens system by the 1st-4th lens groups having negative, positive, and positive composite refractive powers respectively which are succesively aligned from the object side and positively contributing the air spaces between said lens groups to the compensation of aberrations. CONSTITUTION:A titled lens system is constituted by the 1st lens group L1 having negative composite refractive power, the 2nd lens group L2 with positive composite refractive power, the 3rd lens group L3 with negative composite refractive power, and the 4th lens L4 with positive composite refractive powers which are aligned succesively from the object side. When the forcal distances of the whole system are changed by changing the air spaces between the 1st- 4th lens groups, the air space between the 1st and 2nd lens groups and that between the 3rd and 4th lens groups in the short focus side are reduced in the long focus side and the air space between the 2nd and 3rd lens groups in the short focus side is increased in the long focus side. When f1-f4 are defined as the focal distances of the 1st-4th lens roups, conditions f2<¦f1¦, ¦f3¦<f4 and (2) f2<¦f3¦are satisfied. Consequently, a lens system with about 76 deg. image angle, a about 3 times zoom ratio and efficient aberration is obtained.

Title: Addition and subtraction system of floating point data
Inventor: UEDA KOUICHI
IPC: G06F7/76
Filed: 1983-06-09
Abstract: PURPOSE:To reduce the addition/subtraction time of the floating point data by checking the presence or absence of an invalid digit in parallel to the execution of addition/subtraction and therefore the shift amount for normalization is fixed at a time point when the result of addition/subtraction is obtained. CONSTITUTION:When mantissa parts of two floating point data are given to registers OP1 and OP2, an adder 5 performs an algebraical addition of the mantissa parts. At the same time, a carry signal is produced to a specific bit position by a carry look-ahead logic mechanism CLAH4. Then valid patterns (00-0, 11- 1, 11-10) are detected for upper digits from an optional bit by a valid digit detection logic mechanism DET3. Then the carry signal obtained by the CLAH4 and the valid pattern information obtained from the DET3 are fed to a shift amount production logic mechanism. Thus a shift amount which shifts the valid digit is obtained in accordance with a logical equation. Then the arithmetic result obtained from the adder 5 is shifted in response to the obtained shift amount. Thus the addition/subtraction is carried out for the floating point data.

Title: Method for reducing malodor of 2-cyanoacrylate
Inventor: HARUTAKE MASAMITSU
IPC: C09J4/04
Filed: 1990-04-19
Abstract: PURPOSE:To reduce the malodor of an instant adhesive comprising an odoriferous 2-cyanoacrylate by incorporating diethyl carbonate into a 2-cyanoacrylate. CONSTITUTION:Diethyl carbonate is incorporated into a 2-cyanoacrylate, especially an odoriferous 2-cyanoacrylate. A suitable amount of diethyl carbonate to be incorporated is 1-100 pts.wt., preferably 3-60 pts.wt., based on 100 pts.wt. 2-cyanoacrylate compound. If it is too little, the effect of reducing the malodor will be insufficient; if extremely large, the rapid curability of the 2-cyanoacrylate will be deteriorated. As the 2-cyanoacrylate, lower alkyl 2-cyanoacrylates having significant malodor, such as methyl 2-cyanoacrylate, ethyl 2-cyanoacrylate, propyl 2-cyanoacrylate, and butyl 2-cyanoacrylate, are particularly important as objects to which this method for reducing the malodor is applied.

Title: Head shift device in magnetic tape device
Inventor: ITOU MASAO
IPC: G11B5/54
Filed: 1981-07-06
Abstract: PURPOSE:To release an operation between an operating member executing a head shift operation and a cam on the way of the head shift operation, by providing a member locking a control member when the operating member is at pressing position of a head, and energizing the operating member to the operating direction at the lock. CONSTITUTION:A cam 5 is turned by loading a cassette, an intermittent gear 3 unified with the cam 5 in one body is turned and intermeshed with a gear 2 rotated by a motor to shift left a switching member 7. When a roller 10 overrides a maximum point of the cam 5, the intermesh between the gears 3 and 3 is detached and a control member 22 is pushed downward until an operating member 16 reaches the lower limit (pressing position of the head) and locked with a lock member 32. Since a fulcrum 23 of the control member 22 keeps a slight gap from the upper end from a groove hole 21 in this locking state, the tensile force of a spring 27 is effectively exerted on the member 16 and the member 16 can surely be held at the lower end position, that is, the pressing position of the head.
