Title: Driving type frame construction method for underground external wall
Inventor: SUGIYAMA AKIRA
IPC: E04B1/64
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To increase the adhesion on an external wall built using a PC panel as a driving mold form and providing an impermeable layer between concrete and the external wall. SOLUTION: A round separator 41 arranged inside a PC panel 20 used as a mold form is connected to a plate separator 43 through a pin 42 so as to form a separator 40. Also a platy engaging part 44 is formed at the center part of the main body of the plate separator 43 so as to prevent the PC panel 20 from moving toward the inside before concrete is deposited and also prevent a cured concrete 10a, impermeable layer 30, and PC panel 20 from separating from each other after concrete is cured for maintaining the integration of them. When underground water leaks through the cured concrete 10a, the underground water is collected to an unwoven cloth 32 and flows downward along the vertical groove 31 of the impermeable layer 30. Thus water leakage to the indoor side is prevented.

Title: Apparatus for providing surgical skin clip by drilling
Inventor: KAARU BURAUN
IPC: A61B17/10
Filed: 1983-02-08
Abstract: A stapler, particularly for suturing skin wounds or incisions, is disclosed which comprises a channel in which a driver is advanced by a slide in the direction of an anvil surface. A staple magazine which extends substantially parallel with the driver includes a curved section which opens into the channel to deliver staples into the channel for engagement by the driver. During forward displacement of the driver, a projection on the driver presses a leaf spring to which the anvil surface is connected. The anvil surface at the forward end of the leaf spring is thereby brought into its operating position and is automatically moved back into its retracted position upon release of the spring after the driver is retracted. The curved section in the staple magazine enables the stapler to have a slim profile which does not obscure the working area during a stapling operation. After completion of a stapling operation, the anvil surface is automatically retracted from a closed, implanted staple.

Title: Active sonar device
Inventor: ISHII YASUYOSHI
IPC: G01S7/536
Filed: 1989-01-30
Abstract: PURPOSE:To considerably reduce the number of detecting circuits by including the higher harmonic component of a low frequency signal, which is lower than a low frequency signal as the detection object, in the detection object. CONSTITUTION:When a fundamental wave component f3 does not exist but both or either of higher harmonic components 3f1 and 2f2 exists, they are extracted by a narrow-band filter to obtain a detection voltage in a prescribed level in the output of a detector in a detecting circuit which takes the fundamental wave component f3 as the object. Consequently, when the reference level of an amplitude comparator is set to a value lower than the level of the detection voltage for the fundamental wave component f3, existence of both or either of higher harmonic components 3f1 and 2f2 is detected. That is, only one detecting circuit to detect the fundamental wave component of the frequency f2 is required in this device though three detecting circuits to detect fundamental wave components having frequencies f1, f2, and f3 respectively are provided in a conventional device.

Title: Steam transport equipment
Inventor: IKEDA KUNIAKI
IPC: F22B37/47
Filed: 1988-01-29
Abstract: PURPOSE:To prevent air from penetrating into a steam generating drum and enable a stable operation, by opening a passage ON-OFF valve when the steam pressure in the steam generating drum reaches or exceeds the atmospheric pressure after heating of the drum is started. CONSTITUTION:With an operation-starting switch turned ON, a fuel supply ON-OFF valve 12 is opened, a burner 2 is ignited to heat water contained in a steam generating drum 1, and steam is generated with the result of a rise in the steam pressure in the drum 1. When the pressure in the drum 1 detected by a sensor 2 reaches or exceeds the atmospheric pressure, a passage ON-OFF valve 9 is opened through a controlling part 22, and the steam is supplied through a transport pipe 3 to the side of a terminal radiator 5. Therefore, air is prevented from flowing back from the terminal unit side into the drum 1. When the amount of water in the drum 1 is reduced to or below a predetermined level during the operation, the steam penetrates into a feed water pipe 16, and when a temperature not lower than a predetermined temperature is detected by a temperature sensor 18, an equalizing ON-OFF value 14 is opened through the controlling part 22. This causes the steam to be introduced into a feed water tank 15 through a branch pipe 13, and the gas pressure in the tank 15 is brought to the same level as in the drum 1, whereby the water in the tank 15 is supplied into the drum 1.

Abstract: PURPOSE:To improve high temperature durability and a sealing property by using a thermal-plastic material for a resin cover, placing an electric heater between the end edges of the resin cover to heat and melt them, and heat-fusing them while leaving the electric heater as it is. CONSTITUTION:The outer surface of a pipe P is surrounded by a resin cover 1 in a sealing form, and end edges 1a and 1b of the resin cover 1 are overlapped each other. At the same time, an electric heater 2 is placed along the whole area between the end edges 1a and 1b, and pressure plates 3a and 3b at the inner side and the outer side are set to act on the end edges 1a and 1b separately. Then, a current is fed to the electric heater 2 to heat and melt the end edges 1a and 1b, the inner pressure plate 3b is contacted to the pipe P, an external force is applied to the outer pressure plate 3a, and the end edges 1a and 1b are pressed to each other. The current to the electric heater 2 is cut off under such a condition, and the heated and melted end edges 1a and 1b are cooled and hardened in the condition of leaving the electric heater 2 as it is, so as to fuse thermally. After that, both pressure plates 3a and 3b are removed, and the lead wire of the electric heater 2 is cut off to complete the process.

Abstract: PURPOSE:To reduce the space required for loading/unloading a cartridge by constituting an image forming device so as to load/unload the process cartridge on the front side of the device main body. CONSTITUTION:The guide rail 1a for guiding the process cartridge B is disposed in the cartridge loading part of a second cabinet A2. As for the operation for taking the process cartridge out, the second cabinet A2 is pulled out from the opening part of a first cabinet A1 provided on the front side of the device main body A at first. As a result, the first cabinet A1 is gone from the outside of the opening 12 of the second cabinet A2, therefore the cover 11 is projected outside from the opening 12 by the energizing force of the spring, the transfer roller 6 is separated from the photoreceptor drum 2 and the pressurized state between the both is released. Then, the process cartridge B is pulled out from the second cabinet A2 by holding a handle 13b. Consequently, in either case of using the image forming device in a state of being placed vertically or horizontally, the loading/unloading of the process cartridge B can be performed on the front side of the device main body A.
