Title: Optical fiber couplre
Inventor: YAMAUCHI RYOZO
IPC: G02B6/28
Filed: 1995-02-13
Abstract: PURPOSE: To easily produce an optical fiber coupler useful for a bidirectional multiple communication system and to broadly control wavelength characteristics by fusion stretching two pieces of optical fibers having equal parameters and one piece of optical fiber having the parameter different therefrom, thereby constituting an optical fiber coupler. CONSTITUTION: The single mode optical fibers are used for all of three pieces of the optical fibers 1 to 3 constituting the optical fiber coupler 10. The materials having the same parameter are used for two pieces among three pieces and the material having the parameter different therefrom is used for the other one piece. If the fiber diameters of three pieces of the optical fibers 1 to 3 are equal, three pieces of the optical fibers 1 to 3 are paralleled on the same plane and are fusion stretched, by which the optical fiber coupler is formed. If the fiber diameters vary, the optical fibers are fusion stretched by adjusting the central axes thereof onto the same plane. The arrangement of three pieces of the optical fibers 1 to 3 in the fusion stretched part 10a is properly changeable by the coupling characteristics, etc., to be required.

Title: Fluorescent tube
Inventor: FUKUSHIMA YOSHIO
IPC: H01J31/15
Filed: 1986-02-06
Abstract: PURPOSE:To uniformize brightness distribution of a phosphor in a simplified composition, by using a filament only for heating and making conductive layers insulated by the filament serve as function of a cathode. CONSTITUTION:Insulating layers 21 are applied on an outer surface part of a filament 7, with conductive layers 22 piled outside the insulating layers 21. When heating potential is applied to the filament 7, heat is generated from the filament 7 to emit thermions from a thermion radioactive material 8. On the other hand, because resistance of the conductive layers 22 is extremely low, cathode acceleration potential applied to the said conductive layers 22 is kept nearly constant in the longitudinal direction, not generating potential gradient. Thus, when potential distribution of the cathode applied to the conductive layer 22 is nearly uniformized in the longitudinal direction, acceleration of the thermions becomes nearly uniform in the longitudinal direction, with the thermions of nearly the same energy colliding against each phosphor 3. Therefore, each phosphor 3 emits light having the nearly same brightness, uniformizing a brightness distribution in the longitudinal direction of the phosphor.

Title: Fuel injecting apparatus for engine
Inventor: TADOKORO ASAO
IPC: F02D41/10
Filed: 1983-02-15
Abstract: PURPOSE:To improve responsiveness of fuel control, by correcting fuel supply by controlling one of a first and a second fuel injection valves located on the downstream side of the other. CONSTITUTION:A first upstream-side fuel injection valve 5 and a second downstream-side fuel injection valve 6 are provided in an intake passage. The first fuel injection valve 5 injects fuel at the time of low-load operation of an engine while the second fuel injection valve 6 injects fuel at the time of high-load operation of the engine. An operational range judging circuit 17 judges whether the throttle-valve opening is greater than a value predetermined according to the engine speed or not. In case of YES, a signal for changing the mode of fuel injection is produced on the output side of a comparison circuit 19. Thus, it is enabled to improve responsiveness of fuel control.

Title: Recording/reproducing device
Inventor: MARUYAMA FUMIYASU
IPC: G11B15/02
Filed: 1989-02-02
Abstract: PURPOSE:To easily secure the synchronization between a video tape recorder VTR and a digital audio tape recorder DAT by controlling the driving speed of a 2nd magnetic tape of the DAT based on the output of a time code comparator so as to secure the zero difference. CONSTITUTION:The same time codes are written into the linear tracks of a VTR 1 and a DAT 2 respectively. Thus it is possible to decide the synchronizing state between the VTR 1 and the DAT 2 with comparison of time codes carried out regardless of the difference between frame cycles of the oblique scan tracks. Then a magnetic tape 8 of the VTR 1 is driven at a constant speed, and the drive of a magnetic tape 26 of the DAT 2 is controlled based on the output of a time code comparator 3. Thus the coincidence is secured between both time codes of the VTR 1 and the DAT 2. As a result, the VTR 1 and the DAT 2 are substantially synchronous with each other as long as the coincidence is secured between both time codes. In such a way, the synchronization is easily obtained between the VTR 1 and the DAT 2.

Abstract: PURPOSE:To enhance sensitivity and to reduce residual potential even after durability test by using a specified polycyclic quinone type pigment for an electrostatic charge generating layer and a specified ketazine deriv. for a charge transfer layer. CONSTITUTION:The charge generating layer formed together with the charge transfer layer on the conductive substrate of a laminated type electrophotographic sensitive body contains a polycyclic quinone type pigment represented by formula I and. The charge transfer layer contains a ketazine deriv. represented by formula II in which each of R1-R4 is optionally substd. alkyl, aralkyl, or aryl or a residue for forming a cyclic amino group together with an adjacent N, and optionally same or different. It is desirable to form the charge generating layer in a thin film, such as <=10mum thickness in order to contain the charge generating material as much as possible and effectively transfer generated charge carriers to the charge transfer layer, thus to obtain sufficient light absorbance. When the charge transfer material is added to the charge generating layer, it is proper to add the ketazine deriv. in a weight of <=10 times, preferably, 0.01-1 time the weight of the charge generating material for the purpose of ensuring high sensitivity, low residual potential, and stability against repeated uses.

Abstract: PURPOSE:To determine the invaded heat of a long or shape-complicated transfer pipe with good accuracy, by converting an extremely low temp. liquified cooling medium from a supply source to a gas-liquid separated two-phase stream and providing a dewer for supplying said two-phase stream to the transfer pipe. CONSTITUTION:Liquid nitrogen (LN2) supplied to a feed-out dewer 51 from a tank 10 is converted to a gas-liquid separated two-phase stream which is, in turn, supplied to a transfer pipe 22a through a temporarily constructed pipe 20b. Next, LN2 supplied to the pipe 22a through the pipe 20b absorbs invaded heat which flowed through the pipe 22a and, thereafter, only gaseous nitrogen (GN2) is supplied to a branched pipe 22b and GN2 flowed through the pipe 22b is discharged to the open air through a temporarily constructed pipe 20c, a dewer 55 and a heater 12a. At this time, total invaded heat can be calculated from enthalpy of LN2 calculated from pressure measured by a pressure gauge 31, enthalpy calculated from the temp. measured by a thermometer 32b and the flow amount measured by a flow meter 33a and invaded heat measured beforehand is subtracted from the total invaded heat to calculate the invaded heat of the pipes 22a, 22b. Therefore, the invaded heat of a long or shape-complicated transfer pipe can be determined with good accuracy.
