Title: Free-standing floating device
Inventor: NISHIMURA KENJI
IPC: G01S13/75
Filed: 1993-12-21
Abstract: PURPOSE:To maintain the stable free-standing attitude for a long period while a radio apparatus is invariably exposed on the water surface by forming a flotation section with a sliding expansion case made of a double structure of an outer tube and an inner tube. CONSTITUTION:When an emergency situation such as a sea disaster occurs, a valve 23b is opened, gas is spouted from a gas cylinder 23a, force is applied in the direction to expand a case 20, and the case 20 is slidingly expanded in the vertical direction. An outer tube 20a and an inner tube 20b of a double structure are slid in opposite directions respectively until projection sections 200a, 200b are coupled, and the internal capacity is expanded to about two times. The internal capacity of the case 20 is expanded, light gas such as hydrogen gas is filled, thus the specific gravity is decreased, and it is floated when it is put into water. The position of a weight 22 is lowered, the center of gravity is lowered, and it is stabilized at the time of floating. It can be floated on the water surface for a long period in the stable free-standing attitude that a radio apparatus 21 is invariably exposed on the water surface.

IPC: G01J1/02
Filed: 1989-12-14
Abstract: PURPOSE:To stabilize the cooling temperature of an infrared detecting element and prevent an image from varying in brightness owing to output variation by bringing the temperature detection part of a cooler into contact with a cooling block interposed between a discharge nozzle and the internal wall of an internal tube corresponding to the part where the infrared detecting element is provided. CONSTITUTION:A vacuum heat-insulated container in dewer structure consists of an internal cylinder 2 and an external cylinder 4. The infrared detecting element 8 is provided on the vacuum space side of the internal cylinder opposite a light transmission window 6 provided to the external cylinder 4. The Joule-Tomson type cooler 12 detects the temperature in the internal cylinder 2 and controls the opening and closing of the discharge nozzle 10 for gas so that the detected temperature becomes constant. Then the cooling block 16 which has superior heat conductivity is interposed between the nozzle 10 and the internal wall of the internal cylinder 2 corresponding to the part where the infrared detecting element 8 is provided and the temperature detection part 14 of the cooler 12 is brought into contact with the block 16. The heat conductivity of the block 16 is superior to the heat conductivity of air and there is only the internal cylinder 2 interposed between the block 16 and element 8, so the cooling temperature of the element 8 can be held constant.

Subsequently, the resulting hardened body is carbonized by baking in an inert atmosphere, preferably at >= about 1000 deg.C, by which glassy carbon in which porosity is regulated to 0.02-0.20% and no crystallite is detected by means of X-ray diffraction is prepared. Then, at least the part, to be brought into contact with a steel sheet, of a hearth roller is constituted of the above glassy carbon. By this method, the hearth roller having low porosity and superior picking-up resistance can be obtained.

Filed: 1992-11-06
Abstract: PURPOSE:To easily and economically recover a salt hardening and cooling liquid by successively washing the hardened work stuck with a salt liquid in plural washing tanks and concentrating the resulted high-concn. salt-contg. washing liquid. CONSTITUTION:The work is heated to about 750 to 1000 deg.C in a specific atmosphere in a carburization furnace A and the work subjected to the heating carburization treatment is immersed into the salt liquid of about 160 to 250 deg.C in a salt hardening and cooling cell B, where the work is cooled and hardened. The work subjected to the hardening treatment is successively sent to washing tanks 1, 2, 3 where the salt liquid sticking thereto is successively washed away. A specified volume of the salt liquid is ladled into a storage tank D when the washing liquid of the first washing tank 1 attains the prescribed salt liquid concn. after the repetitive conductions of such operations. The corresponding volume of the respective washing liquids in the second and third washing tanks 2, 3 are then ladled back in backward and forward directions of the washing tanks 1, 2. The salt liquid of the specified concn. stored in the storage tank D is transferred at a proper time into a heating and evaporating chamber E, where the salt liquid is concentrated by heating at a suitable temp. The salt liquid is returned to the salt hardening cell B and is reutilized.

Title: Cleaner in image forming device
Inventor: MIHASHI TOSHIHIKO
IPC: G03G21/00
Filed: 1992-12-02
Abstract: PURPOSE:To prevent increase of the pressure of a cleaning blade at both ends during copying by making the holder part of a blade holder excepting a blade sticking surface stronger in structure than a blade sticking part. CONSTITUTION:The blade holder 8 for holding the cleaning blade 7 is bent so that an L-shaped cross-section is formed. A reinforcing member 12 bent so that an L-shaped cross-section is formed is fixed to the upper surface of the bent part of the blade holder 8 excepting the surface to which the blade is stuck by the use of an adhesive. Thus, the amount of distortion made in the blade at both ends during copying decreases comparing with that in a conventional one, so that it becomes almost eaqual to the amount of distortion made in the blade in its central part. That is, since the blade holder 8 of a blade holding mechanism is reinforced, increase of the pressure of the blade at both ends during the copying can be prevented, and filming which occurs on an image carrier during the copying can be prevented.

Title: Lens barrel for zoom lens of camera
Inventor: TANAKA HITOSHI
IPC: G02B7/105
Filed: 1987-12-21
Abstract: PURPOSE:To control the interval between lens groups with high accuracy by constituting the title lens barrel so that a second driving means is operated by a motion of a first lens group supporting frame, a second lens group supporting frame is driven and zooming is executed. CONSTITUTION:An interval between the first and second lens groups 1, 2 is determined by a cam groove 11 which has been formed in a cam cylindrical body 10 operated by advance and retreat of the first lens group supporting frame 3. Thus a second lens group 2 moves forward by a distance which has added a moving extent of the second lens group supporting frame 4 to a moving extent of the first lens group supporting frame 3. Accordingly, the second lens group supporting frame 4 is operated by a motion of the first lens group supporting frame 3, and an interval between a first lens group 1 and the second lens group 2 is determined, therefore, an interval error of the first and second lens groups becomes very small. In such a way, even in case of a zoom lens whose zoom ratio is large, satisfactory focus accuracy is always obtained stably.

Title: Camera
Inventor: DOBASHI HIDEKI
IPC: G03B7/14
Filed: 1993-12-22
Abstract: PURPOSE:To prevent focus displacement and the decrease in consecutive photographing speed at the time of consecutive photographing by changing a diaphragm value in the case of deciding that the moving position of a subject is out of the depth of focus at a previous lens moving position. CONSTITUTION:The depth of focus or a defocusing amount is calculated by a depth-of-focus calculation means 6. In the case of second and succeeding photographing, whether or not the photographing distance of this time is included in the depth of focus(within the defocusing amount regarded as focusing) calculated previous time is decided. When it is out of the depth of focus, the depth of focus or the defocusing amount is calculated again by the means 6 based on the diaphragm value of an AE value which should be shifted, and stored in a photographing information storing means 3, then the diaphragm value is shifted to be within the depth of focus. Thus, the speed of focusing operation is made high, and photographing in focus is realized without decreasing the consecutive photographing speed at the time of consecutive photographing.
