Title: Pressure regulating mechanism for fuel injection device
Inventor: IMAMORI TOSHIICHI
IPC: F02M59/44
Filed: 1995-04-25
Abstract: PURPOSE: To improve a fuel injection characteristic by rapidly lowering spill pressure while preventing cavitation erosion by suppressing the generation of bubbles caused by back flow generated due to the low state of the internal pressure of a pump in relation to the tendency of making the internal pressure of an injection pipe high for a measure to count exhaust gas.

Title: Charged-beam optical mirror tube
Inventor: NAKASUJI MAMORU
IPC: H01L21/027
Filed: 1981-06-30
Abstract: PURPOSE:To increase the beam resolving ability and extend the scanning visual- field of a charged-beam optical mirror tube by restricting the incidence angle of a beam upon a sample surface seen from the vertical direction to below a given value. CONSTITUTION:Instead of using a conventional aperture mask 3, an aperture mask 6 used for restricting a beam like the mask 3 is installed so that the mask 6 is apart from the focus point of an objective lens 1 toward the lens 1. Thus, the aperture mask 6 is located above the lens 1, apart from the lens 1 by a distance (a) (a<f), and the beam center located on the mask 6 is made to correspond to the center of the aperture of the mask 6 by means of beam- positioning deflectors 4 and 5. Owing to the avove constitution, when a beam os irradiated on the same point of a sample surface 2, the beam passes a point which is apart from the center of the lens 1 by a distance (r), whereas the beam passes a point which is apart from the center of the lens by a distance (rt) in the conventional mirror tube (r<rt). As a result, the spherical aberration can be reduced, and any decrease of the beam resolution can be prevented.

Title: Buffer circuit
Inventor: ARAMAKI TAKASHI
IPC: H03K19/00
Filed: 1988-04-25
Abstract: PURPOSE:To turn the level unfixed period of an output signal to almost zero by providing the title circuit with a gate circuit for negating an input signal when the input signal and a control signal are conditions and the control signal is a specific condition. CONSTITUTION:Gate circuits 20A-20D are connected between input terminals 2a-2d and buffer circuits 10A-10D. Even if an enable signal is turned to a negating state to be a high level when an input signal is in a low level, respective output signals of the gate circuits 20A-20D are quickly raised to the high level and then output signals obtained from output terminals 3a-3d are turned to a high level. Thereby, even when the inable signal is in the negating state, a level unfixed period does not exist.

Title: Method for increasing efficiency of copper steam laser
Inventor: SAITO HIROSHI
IPC: H01S3/097
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To increase the laser oscillation efficiency by pumping to a level which is above the upper energy level in laser and is connected to the upper laser level through a fluorescent transition, via a plurality of paths. SOLUTION: The resonance excitation energy level for nickel atoms is 43,090 cm-<1> . A difference in energy level between the resonance excitation energy level for nickel atoms and a level, which is 43,137 cm-<1> and is higher than the upper energy level in copper steam laser and is connected with the upper energy level in laser by fluorescent transition is 47 cm-<1> , which is sufficiently small compared to the kinetic energy based on the temperature of gas in a laser tube and therefore can be easily compensated at colliding. An energy transition phenomenon due to the collision of the second kind is caused, when the conditions expressed by a formula b/v≪h/w are satisfied, and as the difference in energy (Δw) becomes smaller, the transition effect increases exponentially.  In the formula, 'b' is collision coefficient, 'v' is the relative velocity of particles, 'h' is Planck's constant, Δw is the difference in energy between two energy levels related to the collision. Strong pumping via a plurality of paths increases an oscillation efficiency.

Filed: 1988-04-25
Abstract: PURPOSE:To make it possible to prevent the adhesion of sea-organisms to the structure of a sea water channel by applying a very narrow high voltage pulse several times repeatedly to the sea water passing through the entrance portion or the inner portion of the structure of the sea water channel. CONSTITUTION:Larvae of adhesive sea-organisms in the sea water flowing in from the sea water intake 1 are applied with a very narrow high voltage pulse several times repeatedly when passing through a device 5 for applying a very narrow high voltage pulse, and they are kept in paralysis continually or killed and eliminated. Therefore the adhesion and the growth of the larvae to and on the wall of the water intake 2 or the intake side tube channel 4 can be prevented. Under the application of the very narrow high voltage pulse of only one time, the larvae are once paralyzed but recover the activity with time, but by applying the said pulse several times repeatedly the larvae are kept in paralysis continually or killed.

IPC: G06F11/14
Filed: 1980-07-25
Abstract: PURPOSE:To identify whether an error is a fault of hardware or a fault of a retry mechanism by generating an error trap signal only when the error occured in the hardware. CONSTITUTION:When an error occurs in hardware, an ERR-ALU signal ''1'' is applied to an OR circuit 1 which outputs an OR circuit ''1''.

At this tiem, ''1'' is outputted from an OR circuit 4 and since an inverter is provided on the bar output side of an FF5, the bar output signal of the FF5 is ''0''. As a result, an AND circuit 6 outputs ''1'', and an FF7 outputs an RTEN signal ''1'' displaying retry feasibility.

Filed: 1991-05-08
Abstract: PURPOSE:To provide a high-sensitivity and durable information recording thin film capable of being rewritten many times, an information recording member using the thin film and its production. CONSTITUTION:Ruggednesses are provided on at least one surface of an information recording thin film with the physical properties such as phase transition and reversal of magnetization changed by the irradiation with a recording energy beam, and an inorg. protective layer is furnished on the rugged surface. Since the flow of the recording thin film is almost perfectly prevented with respect to a phase-transition optical disk, the frequency of rewriting is drastically increased. Besides, as the line of magnetic force in the recording thin film is not spread with respect to the magneto-optical or magnetic disk, the recording thin film composition even with small vertical magnetic anisotropy is magnetized perpendicularly to the film surface, and the tolerance for the composition is widened.
