Title: Engine preheat device
Inventor: SHIRATA TERUHIRO
IPC: F02P19/02
Filed: 1989-09-29
Abstract: PURPOSE:To perform the feed of quantities of currents by providing a connection control means which connects a capacitor charged by a power source and the power source in series to a heat generating body during output of a rapid preheat command. CONSTITUTION:A battery 1 is connected to a heat generating body 11, e.g., a glow plug, on which a voltage is applied. The battery 1 charges a capacitor 3 through a first relay 2. Control of connection of the relay 2 brings a capacitor 3 into a state to be connected in series to the battery 1. By means of a current discharged from the capacitor 3 during rapid preheat, a current fed to the heat generating body 11 from the battery 1 is increased, and a preheat time is shortened. This constitution performs high-efficient rapid preheat through effective utilization of the characteristics of a self temperature control type glow plug.

Title: Switch controller
Inventor: TANAKA TOSHIO
IPC: H02H7/26
Filed: 1990-09-25
Abstract: PURPOSE:To separate a fault without tripping an electric power substation CB when the fault of a ditribution line is generated by applying AC voltage from a power transformer to a switch as exciting voltage while the application of AC voltage is prevented and the switch is turned OFF when a relay is not operated when the current level of a current sensor is kept within a specified range. CONSTITUTION:A current sensor 5 is connected to a distribution line 2. A level decision circuit 6, a switch 1 and a main switch circuit 7 are further installed. When a fault is generated in a distribution line (the load side) 3 and a current level input from the current sensor 5 is kept within the level decision range iBC of a level decision circuit 6, the switch 1 is opened and controlled before an electric power substation CB is tripped, and the distribution line (the load side) 3, in which the fault is generated, is separated from the distribution line (the power supply side) 2. Accordingly, the switch is opened before the electric power substation CB is tripped when currents capable of being opened by the switch are generated, thus isolating fault without service-interrupting the whole distribution system, in which the fault is generated.

Filed: 1990-09-25
Abstract: PURPOSE:To detect the displacement of a cantilever by a minute force acting on a probe top stable to the external environment with a satisfactory sensitivity by using a Fabry-Perot etalon provided integrally with a probe support member. CONSTITUTION:A laser beam emitted from a semiconductor LD light source 12 is deflected upward by a grating 8 and entered into a Fabry-perot etalon formed of half mirrors 6a, 6b to generate a concentric interference fringe. When a probe 1 is scanned in this state, the interatomic force acting between a sample and the probe is changed according to the surface unevenness of the sample 16, whereby the mirror distance (d) of the Fabry-perot etalon is changed to change the transmitted light intensity of the Fabry-perot etalon, and this is detected by a photodiode 10. The current driver 22 of the semiconductor LD light source 12 is controlled to make the light intensity constant. An arithmetic circuit 19 connected to the current driver 11 receives the information of the injected current to the semiconductor LD light source 12 from the current driver 11 to know the shift quantity of oscillating wavelength of the semiconductor LD light source 12, and calculates the displacement quantity of the probe 1.

Title: Recorder
Inventor: MORIYAMA JIRO
IPC: B41J2/115
Filed: 1985-11-15
Abstract: PURPOSE:To enable characters or images to be clearly printed on a variety of media ranging from a thin medium to a thick medium such as a postal card, by varying an ink ejection starting point according to the thickness of a recording medium used, in an ink jet printer. CONSTITUTION:A recording medium 30 is fed forward in the direction of an arrow A, and when it is passed between a platen 1 and a pinch roller 34, a leaf spring 35 is bent, whereby the size of a strain gauge is varied, resulting in a change in its resistance R1. An output from a bridge circuit 40 arising from the change in the resistance R1 of the strain gauge 36 is inputted to an amplifier 41, and an output from the amplifier 41 is inputted to a CPU through an A/D converter 43. Each of points D, E, F is a desired impact point for an ink droplet, and the distance DP between a point D and the point E is equal to the interval P of encode slits 15. With a timing according to an output from the A/D converter 43 in a thickness-detecting circuit, an ink-ejecting command is sent from the CPU to a printer head driving circuit. Accordingly, an error in the impact point of the ink droplet due to reciprocal motions of a carriage can be reduced, regardless of the thickness of the recording medium.

Title: Coil terminal pin and manufacturing method thereof
Inventor: AOTA HIRONOBU
IPC: H01F27/29
Filed: 1992-09-25
Abstract: PURPOSE:To increase the holding strength of a coil bobbin and a terminal pin for avoiding the falling off and discontinuity of the terminal pin. CONSTITUTION:The recessions 5 are formed in a terminal pin 1 for force-fitting the terminal pin 1 into a coil bobbin. Next, when the resin of the coil bobbin fused by the soldering heat runs into the recessions 5 of the terminal pin 1 and then the soldering heat cools down, the resin is to be set as is so that the holding strength of the terminal pin 1 may be notably increased. Besides, when the coil is wound up, the coil end is caught by the recessions 5 of the terminal pin 1 so that the slippage of the coil end may be avoided by the tension, etc., during the winding step. Accordingly, during another press-fitting step of the terminal pin 1 in the later step, the slack in the coil end can be removed exactly by the amount of press-fitting thereby enabling the failure due to discontinuity to be prevented from occurring.

Title: Receiver for spread spectrum communication
Inventor: KATO TOSHIHARU
IPC: H04B1/707
Filed: 1993-09-20
Abstract: PURPOSE:To reduce power consumption and to make the size small by employing a quadrature demodulation circuit for a circuit demodulating linearly a quadratic demodulation signal obtained by applying inverse spread demodulation to a received spread spectrum signal. CONSTITUTION:A convolution output with quadratic demodulation by a SAW (surface acoustic wave) convolver is inputted to a 90 deg. phase shifter 51. The phase shifter 51 divides a convolution output into two. Then the two different signals outputted from the phase shifter 51 are respectively inputted to two input terminals of a mixer 52. The mixer 52 mixes the two input signals and a mixing output is outputted via an LPF 53. Thus, linear demodulation (quadrature detection) of the convolution output is executed. Since the linear demodulation circuit uses the 90 deg. phase shifter 51 whose insertion loss is smaller than that of a SAW delay line, it is not required to use an amplifier for high frequency amplification in the demodulation circuit and the power consumption is reduced and the shape is made small.

Title: Exhaust gas sensor
Inventor: MORISHITA SHINYA
IPC: G01N27/12
Filed: 1989-09-30
Abstract: PURPOSE:To broaden the range of usable temperature by providing a gas sensitive layer part comprising a metallic oxide indicating gas sensitivity and a metallic oxide at least a part of which undergoes the formation of solid solution and which has the valence larger than that of the above described metallic oxide. CONSTITUTION:A part of a metal oxide whose valence is larger than a metal oxide indicating gas sensitivity undergoes the formation of solid solution. Then, the metal elements of the metallic oxide having the larger valence readily substitutes for the elements in the crystal structure of the metallic oxide indicating the gas sensitivity and readily undergoes the formation of the solid solution. The metal elements having the larger valence act as electron doners for the metallic oxide indicating the gas sensitivity in a gas sensitive layer. Thus, the variation in resistance value in lean and rich atmospheres can be sufficiently secured, and the temperature changing rate of the resistance value in both atmospheres can be decreased. Therefore, the air-fuel ratio can be detected over a broad temperature range without using a heater, a switching circuit for a reference resistor and the like.

Abstract: PURPOSE:To eliminate a wrinkle of paper or a printing fault caused by a slack of paper and to reduce a wear of feed rollers to obtain a longer feed roller life by a method wherein the rotating speed of the feed rollers is varied with the change of the rotating speed of fixing rollers. CONSTITUTION:Fixing rollers 5 adjust their rotating speed in accordance with the angle of a buffer arm 10 so as to keep paper 9 fed from a tractor part 3 tensed at a constant tension. Feed rollers 6 disposed below the fixing rollers 5 deliver the paper from the fixing rollers to a stacker part 8 without a slack while constantly rotating at a speed higher than that of the paper. A rotation control mechanism for the paper feed rollers 6 starts rotating the paper feed rollers simultaneously with the start of printing, e.g. at a speed of 200% of a printing speed. After approximately 1 second elapses, the paper feed rollers are decelerated to 105% of the printing speed. These rollers are stopped simultaneously with the stop of the printing.
