Title: Optical fiber submarine cable
Inventor: NAKAI TAIICHIROU
IPC: G02B6/44
Filed: 1979-01-26
Abstract: PURPOSE: To decrease the pressure increase in the fiber core portion owing to exertion of water pressure and ease repair work by packing high-viscosity material of good wettability in the spacing between optical fiber cords and pressure-resistant structural material for protecting the same.  
     CONSTITUTION: Optical fibers 1 are mechanically reinforced by coverings 2, 2a and a covering 3 is put on the aggregate of the optical fiber cores. High-viscosity material 4 of good wettability and cavity parts 5 are disposed between the covering 3 and pressure-resistant structure 6 by leaving suitable spacings. Under sea water pressure, large pressure is exerted to the submarine cable and this generates internal pressure but the disposition of said high-viscosity material 4 and cavity parts 5 supresses the internal pressure as far as possible and therefore the effect of the sea water pressure upon the optical fiber is made virtually none. In addition, even if the cable is damaged, the entry of sea water into the cable remains locally and therefore the repair may be done simply by replacing the damaged portion.

Title: Method and instrument for measuring temperature
Inventor: NISHIMI YUKIO
IPC: G01J5/60
Filed: 1986-01-16
Abstract: PURPOSE:To stabilize temperature of an object to be measured in a wide range and moreover, to measure the temperature using an inexpensive photodetecting element by calculating a linear difference between output electrical signal levels of two photodetectors by a specific formula. CONSTITUTION:Emitted rays emitted from the object 11 to be measured are made incident on the photodetecting elements 3-1 and 3-2 respectively via filters 2-1 and 2-2. The output rays V1 and V2 are given to a linear arithmetic circuit 6 and a ratio R of the arithmetic outputs N and D is calculated by a ratio arithmetic circuit 4 and sent out to an output terminal 5. Then, the linear difference N (wherein K1 and K2 are constants except zero respectively) between the output electrical signal levels V1 and V2 of the two photodetectors are substantially calculated like an equation in diagram. The temperature of the object to be measured is calculated from the dimensional relation between a value of the difference N and a value corresponding to the reference temperature where the difference N is made zero. In this way, the setting of the reference temperature can be changed freely in the wide range without changing the filters and the photodetecting element. Accordingly, the accurate temperature can be measured in the wide range.

Thus, the toner splashing and the toner spillage are made nearly nil and the clear image is always formed.

IPC: G09G1/00
Filed: 1993-01-21
Abstract: PURPOSE:To provide a flat type cathode ray tube which can reduce man-hour for adjusting and the number of parts and can perform cut off adjusting without deterioration of resolution. CONSTITUTION:Fixed voltage is applied to a cathode electrode K and a second grid electrode G2 of a flat type cathode ray tube 1 by a high voltage generating circuit. A video signal is supplied to a first grid electrode G1 of the first cathode ray tube 1 from emitter junction differential amplifiers 70, 71. Cut off adjusting of the first cathode ray tube is performed by adjusting DC voltage applied to the first grid electrode G1 by a variable resistor 92. Since the cut off adjusting can be performed by only varying DC voltage applied to the electrode 1, man-hour for adjusting can be reduced. Since fixed voltage can be supplied to the electrode K from a voltage source of low impedance, and a capacitor and the like are not required to connect in order to reduce impedance between the electrode K and ground, the number of parts can be reduced. Further, since fixed voltage EG2 is applied to the electrode G2, deterioration of resolution caused by the cut off adjusting can be prevented.
