Title: Apparatus for equalizing rotation of propeller of ship propelling unit
Inventor: IWAI TOMIO
IPC: F16F15/12
Filed: 1984-04-12
Abstract: PURPOSE:To equalize the rotation of a propeller by juxtaposing a first transmission portion having smaller torsional resistance and a second transmission portion having larger torsional resistance between a drive shaft on the engine side and a drive shaft on the propeller side. CONSTITUTION:While an engine is rotated low, output of the engine is transmitted to a propeller through a transmission member 23 connected integrally and rotatably with a drive shaft 18A on the engine side as well as with a drive shaft 18B on the propeller side. Any variation in the rotation of the engine is absorbed by elastic torsional deformation of the transmission member 23. Increased output torque of the engine causes the first transmission member 23 to be torsionally deformed greatly, so that a claw 26 of the second transmission member 24 is allowed to engage with a claw 27 of a connecting member 25. The output torque of the engine can be thereby transmitted to the propeller through the transmission member 24.

Title: Surface treatment of polymer molding
Inventor: SHINOHARA HARUKA
IPC: C08J7/12
Filed: 1981-05-12
Abstract: PURPOSE: To obtain a polymer molding having a surface excellent in water repellency, oil repellency and ice contact resistance, by subjecting the surface of a polymer molding to a fluorination treatment and subjecting the surface again to a postfluorination treatment thereby to fluorinate the chemically active groups produced subsidiarily with fluorine gas.  
     CONSTITUTION: The surface of a polymer molding is subjected to a prefluorination treatment. The chemically active groups (e.g., oxygen-containing functional groups) produced subsidiarily on the superficial layer are subjected to either (1) a postfluorination treatment with fluorine gas at a temperature of about 90W 200°C which is higher than the temperature of the prefluorination treatment, or (2) after hydrolysis, a postfluorination treatment with fluorine gas at a temperature of about 50W200°C which is higher than the prefluorination temperature. With respect to the purity of the fluorine gas, an oxygen content of below 1% is sufficient and, accordingly, commercially available fluorine gas can be used. The thickness of the fluorinated layer (protective layer) formed by the prefluorination treatment can be controlled by suitably selecting the reaction condition for the fluorine gas used.

Title: Production of ethane-based fluorine-containing hydrocarbon compound
Inventor: SEKIYA AKIRA
IPC: B01J27/128
Filed: 1991-03-12
Abstract: PURPOSE:To provide a method for selectively synthesizing a fluorine-containing hydrocarbon compound by carrying out stepwise fluorination of an ethane-based fluorine-containing hydrocarbon compound having terminals of methyl or trifluoromethyl groups. CONSTITUTION:Reactional conditions are suitably regulated by utilizing a phenomenon in which the reactivity of cobalt trifluoride (CoF3) that is a fluorinating agent is reduced with increasing number of fluorine atoms in a fluorine- containing hydrocarbon compound which is a raw material. Thereby, mono- and difluorinating reactions are selectively advanced. An ethane-based fluorine- containing hydrocarbon compound is most expected as a candidate for a nonpollution substitute for chlorofluorocarbons (CFC-11, CFC-12, CFC-113, CFC-114 or CFC-115 regulated due to destruction of ozonosphere) extensively used as polymeric foaming agents, refrigerants, detergents and propellants for spray.

Title: Data imprinting optical system
Inventor: KOIKE KAZUMI
IPC: G03B17/24
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a data imprinting optical system capable of sharply forming a data image such a character or a mark to be nearer to the center side of a curved exposure screen and distinctly forming it without making a camera thick in thickness. SOLUTION: A wedged prism 22 is arranged between a display unit 21 and an image-formation lens 23. The prism 22 positioned so that its top part 22c may face to the optical axis 16a side of a photographing lens 16 and its emitting surface 22b may be inclined toward the optical axis 23a side of the lens 23. An object position seen from the lens 23, that is, the inclination of the surface 22b is freely changed by adjusting the apex angle α of the prism 22, so that the focal position of the lens 23 is moved into a film surface without inclining the display unit 21. Therefore, assembly space in the front- and -rear direction of the display unit is saved in comparison with the conventional data imprinting optical system in which the focal position is moved by inclining the display unit. Since the lens 23 need not be inclined, a surface through which the luminous flux of the data image passes is not extremely deviated to the periphery part of the lens and the influence of the curvature of field of the lens 23 is restrained.

Title: Liquid level detector
Inventor: YAMANE YASUKUNI
IPC: G01F23/292
Filed: 1980-05-28
Abstract: PURPOSE:To constitute optically transparent plates in a simple shape by disposing the optically transparent plates at a constant angle in such a manner that when liquid is in contact with the 1st interface, the light from a light emitting element causes total reflection on the 2nd interface. CONSTITUTION:The liquid to be detected can enter freely the region C enclosed by transparent plates 4 and 6. The point where the light from a light emitting element 7 arrives at the 2nd interface when the liquid enters the region C and contacts with the 1st inteface A is defined as point Q', and the point where the light arrives at the 2nd interface when the liquid is not in contact with the 1st interface A is defined as point Q. The angle alpha of the plates 4 and 6 is so set that the incident angle to the interface at the point Q' attains more than the critical angle. In this case, the greater part of the light arriving at the point Q arrives at a photodetector 8, but the light arriving at the point Q' totally reflects, hence this results in that the light from the element 7 does not arrive at the photodetector 8.

Abstract: PROBLEM TO BE SOLVED: To unnecessitate such complicated work as to manually change print paper which is kept in a printer of a video output device every time by selecting a desired output means among plural output means through an operation of an operating part. SOLUTION: A printer to be used is selected between printers 171 and 172. The operation state of the printer 171, for instance, whether it normally performs a print operation or whether print paper is kept, etc., is checked. Next, the printer 172 is also, similarly checked. When both printers 171 and 172 normally operate in reference to the check result, a printer selection image is shown on a CRT 11 and the selection processing of a printer is performed. On the other hand, when only one printer normally operates, the printer that normally operates is forcedly selected. Thus, because plural printers are provided, for example, when plural types of print paper are used, they should previously be kept in plural printers respectively.

Title: Manufacture of elastic thread winding-up cheese or cone
Inventor: SAKAI TORU
IPC: B65H55/04
Filed: 1988-03-25
Abstract: PURPOSE:To get rid of slack at the time of rewinding by pushing a conical roller having an angle of 10-80 deg. against the shaft of a free roller to both ear portions of a cheese right before or after the end of winding, and making the corner angles of the thread of both ear portions decrease and at the same time giving roundness. CONSTITUTION:A cheese or cone is manufactured as an elastic thread 2 is wound up around a circular bobbin 1. Just before or right after the end of its winding, a conical roller 5 having an angle of 10-80 deg. against the shaft of a free roller 4 is pushed to both ear portions of the cheese or cone. As a result, the corner angles of the thread of both ear portions on the surface of the outer perimeter are decreased, and at the same time, roundness is given to both end portions. Accordingly, the thread 2 at both end portions is shaped into the shape of the thread being gathered up and tightened up toward a center portion, and slack at the time of rewinding diminishes, resulting in the decrease of thread breakages or the like.

Abstract: PURPOSE:To set the incident surface of a reflecting light so as to hold an incident angle with a good efficiency by providing a flexible optical fiber array as the wave guide path of the reflecting light to form an image with an image sensor. CONSTITUTION:An illuminating light L radiated by an illumination light source 1 linearly illuminates in the direction perpendicular to a paper surface at a reading position P point on an original surface 2. The illuminating light L executes the irregular reflection on the original surface 2, and at this time, the intensity of a light reflected at the same angle as the incident angle of the illuminating light L to a normal line erected on the original surface 2 is higher than a light to reflect in the upper direction vertically on the original surface 2 from the P point. By providing a flexible optical fiber 6 so as to face with this in the direction of the reflecting light of the same angle as the incident angle of the illuminating light, a reflecting light La is guided efficiently to an optical fiber array 6.

Abstract: PURPOSE:To cope with the change of characteristics of an R/W head by putting a correction circuit consisting of passive individual parts between the R/W head and a hybrid IC constituting a reproduction circuit without changing the number of lead terminals of the hybrid IC. CONSTITUTION:The reproduction analog given from an R/W head 1 passes through a correction circuit 2 and is supplied to an amplifier circuit via an input circuit 3. The amplified reproduction signal passes through a filter circuit 6 for reduction of noises and is differentiated by a differentiation circuit 7. This differentiated signal is converted into a digital signal by a comparator 8. An error pulse of the digital signal is eliminated by a time domain filter 9. Thus a digital reproduction signal is obtained. A reproduction circuit 11 reaching the filter 9 from the circuit 3 is converted into a hybrid IC. The frequency characteristics of the head 1 and circuits 2 and 3 can be changed within a certain range by varying correction resistances r1 and r2 of the circuit 2. Thus the circuit 11 can be shared by various types of R/W heads.
