IPC: H02K33/18
Filed: 1984-08-30
Abstract: PURPOSE:To make a driving mechanism simple and to execute stable reciprocating shift by inserting a columnar member composed of a carriage in a cylindrical member, supplying pressured air to a clearance between both and preserving the columnar member with a gas bearing. CONSTITUTION:A columnar member 11, where magnets 6-6d for a magnetic circuit are laid underground, is fixed at a base 10, the exciting coil 5 is wound inside and a columnar member 12, to which a head 3 is loaded, is matched and installed. By the composition, when a compressor 13 is operated, pressured air enters a clearance between the cylindrical member 11 and the columnar member 12 and the columnar member 12 is preserved by an air bearing. In the condition, a control current flows at the exciting coil 5, and then, a carriage can be stably reciprocated and a driving mechanism can be made simple.

Title: High speed memory integrated circuit
Inventor: TAKAHASHI KAZUKIYO
IPC: G11C11/34
Filed: 1983-09-29
Abstract: PURPOSE:To attain stable read-write by providing a delay circuit, reset/set flip- flop circuit and a read/write control circuit, and using the pulse edge of an R/W control pulse, and generating a proper pulse suitable for the R/W control at the inside. CONSTITUTION:R/W control signals are inputted from a terminal 20; one is inputted to a reset terminal 22 of the reset/set flip-flop (RS-F/F) circuit 25 via a delay circuit 21, and the other is inputted to a set terminal 26 of the RS-F/F25 not through the delay circuit and they are outputted from terminals 23 and 24 as true logic signal and complementary logic signal. Since a voltage corresponding to an input threshold voltage VTH of the RS-F/F circuit 25 is applied at a point P at a set input terminal 26 of the RS-F/F circuit 25, the voltage waveform set by the RS-F/F circuit 25 rises at the point P and falls down at a point Q. Since the pulse width depends on a delay time (d) of the delay circuit 21, the width is selected optionally by adjusting the delay time.

Filed: 1989-07-14
Abstract: PURPOSE:To assure safe washing, transporting and storing without requiring special equipment by supplying the metal which has a high m.p. and is higher in sp. gr. than Na in a molten state to a separating tank housing the used core constituting elements and removing the Na, then solidifying the metal. CONSTITUTION:For example, the used fuel 2 generated in the reactor core 1 is inserted into a fuel transfer port 6 and is transferred through an out-pile relay layer 10 into the separating tank 12. The metal which has the high m.p., is larger in sp. gr. than Na, does not react with the Na and water and has an excellent thermal conductivity is melted and supplied into the tank 12 to allow the Na previously put therein to flow over the tank. After this Na is removed, the molten metal is naturally cooled and solidified to seal the internal fuel 2. The fuel 2 made into the ingot state is pulled up together with the pot 6 from the inside of the tank 12 and is transferred through a basement 14 and an air cell 13 into an underground storage house 17 where the fuel is stored. The similar method is also applicable to the used control rod and shielding bodies.

Title: Confocal microscope
Inventor: KUMAGAI SATORU
IPC: G02B21/00
Filed: 1994-07-12
Abstract: PURPOSE:To provide the confocal microscope which does not generate shading even if an objective optical system having an axial chromatic aberration and magnification chromatic aberration is used by providing a light shielding member with a pinhole of a size including the moving range of the light condensing point of the return light generated according to the movement of an optical path by a deflecting optical system. CONSTITUTION:Polarized light is condensed onto a sample 50 and the return light from the sample 50 is condensed at a position conjugate with the condensing point on the sample 50 and is further detected via the light shielding plate 62 with the pinhole. The size of the pinhole 62B of the light shielding plate 62 is set at a size inclusive of the moving range of the condensing point of the return light generated according to the movement of the optical path by the polarizing optical systems 31, 33. Then, the fluorescent spot on the light shielding plate 62 moves and the greater part is capable of passing the pinhole 62B even if the spot exists in the position furthest from the optical axis and, therefore, the light arriving at the photodetectors 63a, 63b does not decrease. The fluorescence emitted from the sample 50 is detected without being shut off by the light shielding plate 62 even if the fluorescence is from any position on the sample 50.

Abstract: PURPOSE:To improve the adhesive powder, density and vapor deposition speed of a film by projecting a laser beam again to an evaporating material at the time of projecting the laser beam to the target material to evaporate the target material and to form the film. CONSTITUTION:A laser beam 7b which is included in an incident laser beam 7 and is transmitted through a partial reflection mirror 9 is reflected by a total reflection mirror 10 to enter the inside of a chamber 1 in which a vacuum state is maintained. The target material 5 is irradiated with said beam. The target material 5 is directly evaporated by the irradiation and the evaporating material 6 is fed to a base material 3. On the other hand, the laser beam 7a reflected by the partial reflection mirror 9 passes the transparent window 8a of the chamber 1 and enters the inside of the chamber 1 where the evaporating material 6 is irradiated by said beam. Since the evaporating material 6 is pulverized at the time of the irradiation, the material absorbs the energy possessed by the laser beam 7a with high efficiency, by which the ionization degree, etc., of the evaporating material 6 are improved and the activity thereof is improved. The evaporating material 6 improved in the activity sticks onto the surface of the base material 3 to form the film 4.
