Title: Power supply
Inventor: OKAWA MASANAO
IPC: H05B41/24
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a power supply which is protected against breakdown by detecting the load current even upon short circuit of the output line to a load and in which a transformer having low breakdown strength can be used. SOLUTION: The inventive power supply comprises a DC power supply E, a DC converter circuit 1 for converting a DC voltage connected with the DC power supply E, and an inverter circuit 2 connected with the output of DC converter circuit 1 and supplies a rectangular wave voltage to a load Lp connected with the output end of the inverter circuit 2. A rectangular wave voltage having a potential lower than that at the negative end of DC power supply E is fed to the load Lp by connecting the negative end of DC power supply E with the positive end of DC output from DC converter circuit 1. The load current is detected by inserting a current detection means (resistors Rd1 , Rd2 ) into a path extending between the positive and negative ends of DC output from DC converter circuit 1.

Title: User interface device
Inventor: HOSOMI ITARU
IPC: G06F3/048
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To give the guidance to a user according to the relevant situation even when it's impossible to decide what to do next by giving the guidance to the user in response to the time when the measured time is equal to any one of times elapsed which are included in the guidance knowledge. SOLUTION: A time measurement part 16 measures the time elapsed after a user performed no input operation any more. When the part 16 detects the lapse of the time that is previously designated and notifies a dialog control part 12 of the detected time, an automatic guidance part 14 takes the guidance knowledge out of a guidance knowledge management part 15 in response to each time elapsed. Then the proper answer contents are selected among those guidance knowledge, and the guidance is given to the user via a text output part 19 and an impersonate answer part 20. Furthermore, an application information retrieval part 17 retrieves an application data base 18 in response to the request given from the part 12.

Abstract: PURPOSE:To enable separation of radioactive substances with small generating amount of radioactive waste and a comparatively small and simple device by using an adsorptive body of which G value regarding exchanging capacity is smaller than 1.8, for separation of th radioactive substances. CONSTITUTION:Structural change of adsorptive bodies by radiation received during the same operation time, is evaluated by change of exchange capacity related to adsorption capacity of the adsorptive body, and the change of the exchange capacity is defined as the G value of the exchange capacity, that is to say, the decreasing number of exchange radicals per absorbing radiation energy, 100eV.

Title: Forming roll for electric resistance welded tube manufacturing equipment
Inventor: NAKAMURA YOSHIHIRO
IPC: B21D5/12
Filed: 1987-10-23
Abstract: PURPOSE:To improve the forming quality of an extra thin electric resistance welded tube by arranging a fin and rollers of a forming roll around an axis so that they can rotate to each other. CONSTITUTION:An upper pass roll 21 is constituted by tightening pass rolls 23, 24 with bolts 30 and the fin is fitted in the center of a semi-circular recess 27 and rotatively around an axis 33. In this case, the fin 26 is supported by a bearing 25 and a suitable clearance for sliding is provided between the pass rolls 23, 24. When a strip stock 20 is formed, the rotation radius is different according to a contact position to the fin pass roll 21 but since the fin 26 can rotate to the rolls 23, 24, the turning force of the fin pass roll 21 acts only on the outer circumferential surface of the strip stock 20, but not on end surface part 32. Accordingly, the composite stress acting on the strip stock 20 is reduced, the end part 32 is prevented from buckling and the forming quality is improved.

Title: Optical system of grating lens
Inventor: NAKAI TAKEHIKO
IPC: G02B5/18
Filed: 1989-10-13
Abstract: PURPOSE:To hardly generate the fluctuation in wavelength by the mode hop arising from return light by disposing the grating lens in the state of inclining the rear surface with respect to a light source. CONSTITUTION:The grating lens 2 is disposed in the state of inclining the rear surface thereof with respect to the light source 1 so as to prevent the reincidence of the return light from the rear surface of the grating lens 2 to the light source 1. The beam emitted from the light source 1 is emitted as collimated beam of light in the grating part 3 of the grating lens 2. The grating lens 2 is changed in the thickness of the lens base plate in order to prevent the return light. Since the thickness varies in such a manner a ray OA and a ray OB vary in the optical path length, i.e. phase, but this phase difference is adjusted by changing the grating part 3 to such a shape as to correct the phase difference of this thickness component. The mode hop of the light source which generates the mode hop by the return light is suppressed in this way and the change in the focal length by the fluctuation in the wavelength exclusive of a change in temp. is suppressed.

Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To reduce a torque at the time of shift by accurately sensing shift by means of an engine controlling CPU in a hydraulic controlling automatic transmission. SOLUTION: Shift is not determined when a throttle opening TVO is varied to a decreasing side (S11). The shift is not determined neither, when fuel is cut against excessive rotation under high speed rotation (S12). Shift starting is determined when an engine speed N is decreased under other conditions than above (S13). Shift completion is determined when the rotation speed reaches a specified value or lower after starting shift (S14). Torque reduction control is performed based on the determination, from the starting to the completion of the shift, while retarding an angle of an ignition timing.

Abstract: PURPOSE:To obtain large-area images by oxidizing the coating film of a soluble conjugation type polymer to insolubilize the film, then subjecting the film to photoirradiation in the soln. of this polymer, thereby solubilizing the film. CONSTITUTION:The soluble conjugation type polymer is applied, on a base material to form the coating film and thereafter, the film is electrochemially or chemically oxidized (doped) to isolubilize the soluble conjugation type polymer.
