Title: Heat exchanger tube for steam generator and its manufacture
Inventor: FUJIWARA TETSUO
IPC: F28F1/00
Filed: 1988-09-09
Abstract: PURPOSE:To miniaturize the size of a steam generator, by laying out an inner tube and outer tube made of iron-based alloy steel so that their cross sections may become a concentric circle, and allowing a porous member having excellent heat conductivity and porosity exceeding a specified % to exist between said inner pipe and outer pipe. CONSTITUTION:A double tube type heat transfer tube 102 has a porous member 111, which is provided with excellent heat conductivity, existing between an inner tube 103 and an outer tube 104, and their porosity is specified to 3% or more. The inner tube 103 and the outer tube 104 comprise high chrome steel, for example. The leakage caused by a crack produced on the surfaces of the inner tube 103 or the outer tube 104 is spread through the pores within the porous member 111, which is excellent in heat conductivity, and is transmitted promptly in the axial direction of the tube, which makes it possible to detect the generation of damage earlier than the conventional mechanism. Therefore, this construction can satisfy both damage detection performance and heat transfer performance, which are under antinomic relation each other in the prior art embodiment. If the porosity fails to exceed 3%, gas permeability will be insufficient and difficult to detect the generation of leakage.

Title: Developing device
Inventor: SHIMIZU TAMOTSU
IPC: G03G15/08
Filed: 1987-09-08
Abstract: PURPOSE:To form a superior image without varying the conveyance amount of a developer even if the main pole of an internal magnet shifts in position by providing a nap height control plate which is displaced in correspondence to the angular displacement of the main pole of a magnet roller facing the surface of an image formation body. CONSTITUTION:One end of the nap height control plate 4 is fixed to the shaft 14 of the magnet roller by a coupling member 11a and the other end is supported rotatably by a developing sleeve shaft 13 through a bearing 12 and rotates by the same angle as the adjustment rotational angle of the magnet roller 3 while having a constant control gap P with a developing sleeve 2. Therefore, the main pole N1 and nap height control plate 4a are only set previously and then when the main pole is moved to a position N2 by varying the main pole angle by delta, the nap height control plate rotates similarly by delta to move a position 4b, but the position relation between the nap height control plate and main pole does not change. Consequently, even if the main pole angle of the magnet roller varies, the constant conveyance amount of the developer is obtained.

Title: Waveguide type acoustooptical spectrum analyzer
Inventor: NISHIMOTO YUTAKA
IPC: G02F2/00
Filed: 1985-10-11
Abstract: PURPOSE:To improve a dynamic range by removing undeflected light from the plane optical waveguide of a waveguide type acoustooptical (AO) spectrum analyzer. CONSTITUTION:Collimated light 15 is deflected with a surface acoustic wave 19 generated by an electrode 18 for surface acoustic wave generation to generate deflected light 16 while undeflected light 17 also remains. The deflected light 16 and undeflected light 17 are propagated at an angle twice as large as the Bragg's angle determined by the wavelength of the light, the oscillation frequency and propagation speed of the surface acoustic wave 19, and the refractive index of the plane optical waveguide 11, so the deflected light 16 and undeflected light 17 are separated in the waveguide 11. Only the undeflected light 17 is removed from the waveguide 11 by a reflecting material or absorbing material 21 and only the deflected light 16 is converged by a plane lens 14 to reach a signal photodetection end surface 22, so that the light is detected by an array type detector 20. Therefore, scattering loss generated at the lens 14 owing to the undeflected light 17 and propagation loss generated from the lens 14 to the detection end surface 22 are eliminated, so a noise signal detected by the detector 22 is reduced greatly, so that the dynamic range is improved.

Abstract: PURPOSE:To improve the amplifying speed of a sense amplifier which performs rewrites and to speed up a data transfer operation by using a capacitive coupling for data transfer with a simple circuit constitution and approximately suppressing the potential difference between a pair of bit lines after a transfer to an initial potential difference. CONSTITUTION:When a signal DT1 becomes high by the data held in a masking register 6-1, a dummy cell plate equalizer 8-1 becomes non-conductive, a transfer gate 4-1 becomes conductive, the data held in a serial data register 5-1 appear on a dummy cell plate pair CP1 and the potential of the pair CP1 changes from a VCP potential to high and low. Thus, the potential difference of a pair of bit lines BL1 changes by the capacitive coupling of cell capacitors of dummy cells 7-1 and 7-2. Thereafter, a sense amplifier driving signal SADR drives a sense amplifier 3-1, the signals on the pair BL1 are amplified and the contents of a memory cell 1-1 are updated.

Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To facilitate the manufacture by eliminating the need of forming a driving means on the wiring boad by using an electrostatic driving means and to obtain high fineness without being restricted by the line width of wiring. SOLUTION: The electrostatic driving means is used as the driving means of the device. Namely, a corona charger is used for an electrostatic charging process to raise the potential of the top surface of a photosensitive body. An arbitrary area on the electrostatically charged photosensitive body is exposed by an exposing unit. When a liquid crystal panel is brought into contact with the photosensitive body where a latent image is formed, an electric field is produced in the liquid crystal panel. At this time, a conductor layer is provided on the back side of the liquid crystal panel and applied with a voltage having the same polarity with the electrostatic charging of the photosensitive body. Then when electric charges of the photosensitive body are transferred while a bias is applied, an electromagnetic field is produced in the panel.  The produced electric field is different between an area where the photosensitive body is charged electrostatically and an area where the photosensitive body is not charged. An electrostatic discharging means removes electric charges left on the photosensitive body and liquid crystal panel.
