Title: Signal generator for inspecting accuracy of horizontal axis of oscilloscope
Inventor: TAKAHASHI HISAO
IPC: G01R35/00
Filed: 1994-07-20
Abstract: PURPOSE:To immediately inspect whether horizontal axis accuracy is within an allowable error by displaying an output signal having a central edge at one edge of a rectangular wave, and righthand and lefthand edges showing an allowable error range of the horizontal axis accuracy. CONSTITUTION:A variable divider 12 and a sawtooth-wave generator 16 output a dividing reference signal A and a sawtooth-wave signal B. A D/A convertor 18 outputs d.c. voltage C in response to data from MPU 14. A voltage comparator 20 rises when signal B > voltage C, and outputs a comparison signal D which falls when signal B<voltage C. A phase comparator 22 outputs an accordance signal E at the time when rises of the signals A, D are matched to each other. MPU 14 regulates voltage C and accumulates a value corresponding to output voltage Ca at the time of output of the signal E. The voltage corresponding to a horizontal axis error allowable range is found, upper limit and lower limit voltages Cb, Cc are found out, and the voltage C is changed into the voltages Ca, Cc, Cc. Comparison signals Da, Db, Dc for level- changing at an intersection of these and the sawtooth wave are produced, and an allowable error range is displayed on the screen of an oscilloscope as central. righthand and lefthand edges.

Title: Temperature-detecting circuit
Inventor: TERADA YUKIHIRO
IPC: G01K7/01
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce a count of parts and cut costs by connecting a series body of a plurality of resistance elements in parallel to a temperature-detecting element and connecting both ends of the middle resistance element to input terminals of a comparator. SOLUTION: A series body of, e.g. three resistors 14-16 are connected in parallel to a diode 12 between a connecting point 13 of a current source 11 and a temperature detection diode 12 and the ground. Both ends of the middle resistor 15 are connected to a non-inverting input terminal 18a and an inverting input terminal 18b of a comparator 18. In this constitution, a voltage drop by the resistor 15 provides an offset to inputs of the comparator 18.  Along with a temperature rise, potentials of connecting points 20, 21 decrease in accordance with a potential decrease at the connecting point 13, and a voltage at both ends of the resistor 15 at a temperature Ta where the comparator 18 changes its state, namely, a potential difference between voltage-temperature conversion characteristics (b) and (c) is input as a potential difference changing in accordance with the temperature to the comparator 18. Accordingly, a temperature characteristic reference power source is eliminated, thus decreasing a count of parts.

Title: Fuel injector
Inventor: YAMADA HIROATSU
IPC: F02M51/06
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injector easily performing an assembling work. SOLUTION: A stopper 40 is formed into an annular-shape and has a projecting part 41 projecting to the outside in the diameter direction. A positioning groove 3a extends in parallel to the mounting direction of an injector 10. By inserting the projecting part 41 in the positioning groove 3a, the projecting part 41 is restrained by the positioning groove 3a in both the revolving directions of the injector 10. Therefore, the mounting work of the injector 10 and the connecting work of a fuel piping 50 become easy because the revolution of the injector 10 is regulated when the works are performed. The injection characteristic of the injector 10 can be held because torsional force when the fuel piping 50 is connected does not work on magnetic circuit constitution members and injection quantity metering members.

IPC: F21S2/00
Filed: 1994-08-11
Abstract: PURPOSE:To easily enhance the illuminance of line lighting without changing the directivity of incident light by converging light generated from each point light source to integrate it with an optical fiber and making it to be incident upon a transparent rod from the end surface thereof. CONSTITUTION:Light generated from a plurality of point light sources is converged by a concave mirror 3, integrated with an optical fiber 10 and made to be incident upon a transparent rod 1 formed of a transparent optical material having refraction factor larger than that of air from the end surface of one end side. Further, the incident light 5 is exposed to a total reflection lattice 6 inside the rod 1 for total reflection and emitted as line lighting from the side surface of the opposite side of the lattice 6 to produce lighting 8 on an object material 7. The lattice 6 is formed with plane accuracy so that the exposed light is not diffused and cut off at a total reflection angle. The directivity of the incident light onto the rod 1 is kept and at the same time the illuminance of the lighting 8 by the number of the light sources 2 is obtained. Since the end surface of the other end side of the rod 1 is made into a mirror surface 11, the incident light 5 is made so as not to run away from the end surface.

Filed: 1985-08-30
Abstract: PURPOSE:To adjust the smooth invalid electric power simply and to eliminate the necessity of the maintenance almost by turning and positioning relatively the winding type rotor and the stator of the shifting device. CONSTITUTION:Switches S1-Sn and S1'-Sn' are all opened, so that a delay invalid electric power adjusting device 6 can obtain the maximum delay invalid electric powe, the rotational angle of a winding rotor 1 of a phase shifter M is adjusted to 180 deg. by a worm 5 to a stator 2. Next, switches S1' and S1 are inputted. At such a time, since the invalid electric power obtained by a capaci tor C1 and the delay invalid electric power obtained by the device 6 are equal, the total invalid electric power comes to be zero. Next, so that the invalid electric power obtained by the device 6 can come to be small, a rotational angle theta of the rotor 1 is decreased, the rotational angle theta is brought to 0 deg. and the switch S1' is opened. In the same way hereinafter, capacitors C2-Cn are proceeded and the invalid electric power is obtained. Thus, the total capacity of the phase shifter M and a transformer T can be decreased to 1/n of the capacitor K.

Title: Fet mixing circuit
Inventor: HARUKI HIROSHI
IPC: H03D9/06
Filed: 1981-11-26
Abstract: PURPOSE:To realize stable operation, by preventing oscillation due to stray capacitance, through the provision of a DC bias to a gate electrode via a matching circuit. CONSTITUTION:An input signal is given to a gate electrode G1 via a matching circuit 10 from a terminal. A local oscillation signal is given to a gate electrode G2 via a matching circuit 11. Matching circuits 10, 11 are both of DC passing type. A DC bias voltage is supplied to the gate electrodes G1, G2 via the matching circuits 10, 11. Since the impedance viewed the gate electrodes from the input of the matching circuits 10, 11 is 50 ohms equal to that of a transmission line, the reactance of choke coils 12, 13 separating a DC bias voltage source and a high frequency signal can be made small. Since the reactance is small, terminals 2, 3 can be regarded as ground with respect to IF frequency, stable can be realized without signals from other routes.
