Inventor: MINEO SUMITAKA
IPC: B63C3/02
Filed: 1993-12-27
Abstract: PURPOSE:To launch a ship easily and without any concern about the overturn thereof by supplying a fluid like the air into each bag body of many bag type jacks under pressure for keeping a ship afloat from a launching way.

Title: Optical recorder
Inventor: INUI TETSUYA
IPC: G11B7/135
Filed: 1988-12-27
Abstract: PURPOSE:To make the area of a light spot small and to improve recording density by making the intensity of a laser beam which reaches the outer peripheral side of an objective lens intenser than that of a laser beam which reaches the inner peripheral side of the objective lens relatively. CONSTITUTION:The laser beam 2 emitted from a semiconductor laser 1 is turned into the collimated beams of light by a condenser lens 3, transmitted through a beam splitter 4 and a filter 5 and made incident on the objective lens 6. Since the filter 5 has such characteristic that the absorption factor of light gets larger as you go from the outer peripheral part to the center part, the intensity of the laser beam 2 which passes the filter 5 in the outer peripheral part is relatively larger than that in the center part. Thus, the size of the light spot 9 condensed on a recording medium 8 by the lens 6 can be made small. Therefore, high density recording is performed without using an objective lens whose numerical aperture NA is large.

Title: Filter for casting
Inventor: HIROMOTO SHUJI
IPC: B22D18/04
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce a production cost by using a porous material composed of heat resistant metal or alloy having higher m.p. than molten metal and sintered while entwining metallic fine wires having a prescribed range of wire diameter as a filter for casting to prevent the flow-out of fiber material and molten metal from a gas exhaust hole for reducing the pressure. SOLUTION: The fiber F is filled up in a mold 1 and a switch valve 2 is closed and the air in the mold 1 is evacuated and the pressure is reduced. Then, the switch valve 2 is opened and the molten metal M is poured into the mold 1 and hardened. Therein, the filter 5 is served so that the air in a metallic mold is passed through but the fiber F and the molten metal M is not passed through. However, even if the filter is brought into contact with the molten metal, the filter has heat resistance without melting and oxidizing and further, the filter can easily be separated after solidifying the molten metal. Concretely, this filter is composed of the porous material sintered by entwining the metallic fine wires composed of the heat resistant metal or alloy having the higher m.p. than the molten metal and 20-100μm wire diameter.

Title: Contact electrifier, image forming device and process cartridge
Inventor: OTSUKA KEIZO
IPC: G03G15/02
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To reduce an amount of abrasion of the surface of a body to be electrified and to prolong the life of the surface of the body to be electrified, by allowing a DC electric field to be applied to an electrifying process means so as to overlap an AC electric field to electrify an image area when an image is formed, and allowing only a DC electric field to be applied to the electrifying process means to electrify an image non-formation area. SOLUTION: As long as image formation is carried out under the application of a bias, -700 V can be obtained as the surface potential of a photoreceptor 8 up to, for example, 50000 sheets of A-4 size in a lateral position, and satisfactory images can be provided. However, at th point of time when the number of sheets exceeds 50000, the surface potential decreases. It decreases up to approximately -600 V at the point of time that the 50000-th sheet is used, so that a fog image in which toner is stuck to the white background of an image occurs.  To counteract this, as an application bias, only a DC constant voltage of -1500 V is applied to an area between the sheets, that is, an image non-formation area where an image to be formed is not followed by another, and a DC constant voltage of -750 V, an AC constant current of 1900 μ A, and a frequency of 1800 Hz are applied to an image formation area. This eliminates the occurrence of a fog image caused at a point of time that the 50000-th sheet is used.

Title: Photographing device
Inventor: OGURA SHIGEO
IPC: G03B15/05
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of a main emitting light quantity by controlling the main emitting light quantity, based on a pre-emitted light quantity. SOLUTION: A system controller 5 for controlling the whole of an electronic camera controls strobe photographing by a stroboscope 6 and a light control sensor 7, to calculate a light control level. At the time of executing the strobe photographing, the pre-emission of light is performed before the emission of the light for photographing. Light control for the emitted light quantity at the time of pre-emitting the light is adjusted in a state where a fixed light control level is set and the emitted light quantity of the stroboscope for photographing is controlled with photometric data on the luminance of an object and the light control level, at the time of pre-emitting the light.  Further, the light control level used for adjusting the light control of the emitted light quantity for photographing is calculated with the photometric data and the light control level, so that the light control of the emitting light quantity for photographing is adjusted in the state where the calculated light control level is set. Since the main emitting light quantity is made proper according to the pre-emission of the light, proper strobe photographing can be executed without the influence of the position and reflectance of the object.

Title: Method and device for determining disturbance and/or occupancy frequency channel of mobile communication system
Inventor: KAINDL ROLF
IPC: H04B7/26
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To inexpensively and easily test a mobile telephone at the specified point by detecting a measurement report parameter with each channel(CH) to be measured at a suitable RF level, comparing it with a threshold value and recognizing the searched CH as a disturbance and/or occupancy CH when there is a remarkable difference. SOLUTION: After the mobile telephone is registered to a testing device at the high RF level of CHn=1 of a bottom frequency, the RF level is lowered and an RXQUAL parameter(RQP) is read out inside the CH. When the difference of RQP > expected value is large, a correspondent CH number and a correspondent RQP are stored, this method is switched to CHn+1 and when there is no difference, switching to the next CHn+1 is performed at the high RF level. Corresponding to whether the final CH is reached or not, the stored RQP and CH number are displayed while being related and the process after the registration is repeated. Thus, it is not necessary to provide an expensive spectrum analyzer and the disturbance and/or occupancy frequency CH at the specified geographical point can be determined.
