Title: Fuel injection control device of diesel engine
Inventor: MATSUNO KIYOTAKA
IPC: F02B3/06
Filed: 1982-04-05
Abstract: PURPOSE:To prevnent abnormal rise of the chamber temp. generated by difference of the injection amounts due to secular change etc. by sensing the chamber temp. of the engine and by reducing the amount of fuel injection when this temperature is continued for a certain set period of time or frequence in occurrences. CONSTITUTION:At the time of driving, a control device 3 shall first calculate the fundamental amount of fuel injection from outputs of an electromagnetic pick- up sensor 20 and an acceleration sensor 9. Them it shall be judged whether the chamber temp. Tc given by a chamber temp. sensor 51 is above the limit valve (for ex., 910 deg.C), and if Tc<910 deg.C, a judgement of normal condition is issued to set the fundamental amount of fuel injection as the final amount. If Tc>910 deg.C, on the other hand, a chamber temp. over-counter is stepped forward, and when the number of steppings has attained a certain value, a judgement of abnormal chamber temp. condition is made. When this judgement was issued, the fundamental amount of fuel injection is reduced by a certain specific value to set this reduced value as the final amount.

Title: Stepping motor driving equipment
Inventor: IWABAYASHI KAZUYA
IPC: H02P8/12
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To reduce vibrations and noises, without decreasing the output torque, and improve both the output torque characteristic and vibration characteristic. SOLUTION: Current limit setting change signals IRCA and IRCB are outputted to drivers 2 and 3 from an excitation control circuit 6. When the signals IRCA and IRCB are in 'H' period, the drivers 2 and 3 change a current limit setting value which defines the upper limit of absolute value of currents flowing in stator coils 4 and 5 into a lower side current limit setting value. While a current value of the stator coil 5 increases up to the upper side current limit setting value, in a period from a time t1 to a time t2, a current value of the stator coil 4 decreases and is maintained to be a lower side current limit setting value. Comparatively weak hysteresis break of the stator coil 4 is applied to a rotor for a comparatively long term, so that the rotor rotates smoothly and the output torque is not drastically deteriorated.

Title: Stealth type ink composition and recording using the same
Inventor: MAEKAWA TSUTOMU
IPC: C09D11/38
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a stealth type ink composition which does not limit a recording medium, enables high speed recordings, is mild for environments, and can solve troubles, such as insufficient adhesivity to recording media, low recording rates, and insufficient safety, in the cases of liquid ink jet recordings. SOLUTION: This hot melt type ink composition is used by thermally liquidizing the ink composition which is solid at room temperature, and then imparting any jet energy to the liquidized ink composition, thus allowing ink drops to jet on a recording medium to form recording drops. Therein, the ink composition contains a luminous substance which does not exhibit remarkable absorption in the visible light region but emits visible light, when irradiated with UV light, and uses an ink vehicle which does substantially not have an absorption peak in the range of 300-400 nm. The ink composition preferably contains one or more compounds selected from monoamides, ester amides and bisamides in an amount of >=50 wt.% based on the ink composition, and has a melting point of >=70 deg.C.

Title: Gas-insulated cable
Inventor: INAOKA KAZUYOSHI
IPC: H01B9/06
Filed: 1978-05-15
Abstract: PURPOSE: To raise the current capacity of a gas-insulated cable, by winding a woven band net of large meah to a plurality of layers on a conductor, coating the net with a metal sheath and filling an insulating gas in the sheath.  
     CONSTITUTION: The large-mesh insulator band net made of filaments of glass fibers or thermoplastic resin such as polyethylene is spirally and continuously wound on the conductor 1 in the longitudinal direction thereof. The net is coated with the metal sheath 3. The insulating gas is filled in the sheath 3. An anticorrosive layer 4 is provided on the outside surface of the metal sheath. Since the insulating gas performs convection at a sufficient flowing speed through the insulator net 2, the heat resistance is low and the heat transfer from the conductor 1 is high. This enables the increase in the current capacity of the cable. The distance between the conductor 1 and the sheath 3 is kept constant. Because the insulator net is flexible enough to be easily wound on the conductor, the production cost of the cable is reduced.

Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment of a parallax correction amount in a manufacturing stage and to change the parallax correction amount even in a using stage by adjusting the interval between prism groups for deflecting a luminous flux in a direction nearer to an optical axis and to make the luminous flux nearly parallel with the optical axis. SOLUTION: The first prism element 12a of a parallax correcting means 12 has the function of deflecting the luminous flux in the direction nearer to the optical axis of a photographic lens and individually functions as a first prism group. A second prism element 12b has the function of deflecting the luminous flux in the direction away from the optical axis of the photographic lens. A third prism element 12c has the function of deflecting the luminous flux in the same direction as that of the first prism element 12a. Then, the second and third prism elements 12b and 12c function as a second prism group having the function of deflecting the luminous flux upward by both of the elements 12b and 12c. Thus, the first and second prism groups can vary the shifting quantity between incident and outgoing light beams by the change of the spacing between the first and second prism groups.
