Title: Manufacture of cathode filament coil for x-ray tube
Inventor: AKITA KOJI
IPC: H01J9/02
Filed: 1994-01-18
Abstract: PURPOSE:To increase the quantity of thermodelectron emission without causing cracks on a coil by keeping a proper angle between the axial direction of a core wire and the axial direction of coiling and coiling an elemental wire densely on the core wire. CONSTITUTION:The pitch 11a of a filament coil 11 in the axial direction is narrowed and a wire to be coiled is coiled densely to narrow the gap 11b between turns of the wire, and the axial direction 12 of a core wire and the axial direction of coiling are set to be at a proper angle theta. The coil 11 is thus prepared by coiling an elemental wire 42 on the core wire 41 while tilting in the axial direction 12, and the coil extended length per one pitch becomes long and the curvature becomes wide, so that no unnatural force affects the coil elemental wire 42. As a result, coil (cracking does not occur and effective thermoelectron emission surface area can be widened by making the pitch of the coiling dense and the quantity of thermoelectron emission wire 42 on the core wire 42 into is prepred by coiling the elemental wire 42 on the core wire 42 into a cylindrical shape and the coil's curvature is not altered, the size precision is heightened and the resulting coil can be used as a coil for a cathode of an X-ray tube with narrow focus and small tube current.

Title: Inverter
Inventor: DEGUCHI TAKASHI
IPC: H02P6/08
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency by controlling the conduction angle variably such that a three-phase inverter sets the conduction waveform of a DC three- phase brushless motor within a specified angle per phase thereby preventing the ON loss and switching loss due to forward voltage drop. SOLUTION: Voltage of an AC power supply 1 is converted into a DC voltage and then passed through an inverter 3 to produce a pseudo AC voltage which is applied to a DC three-phase brushless motor 4. The inverter 3 controls the conduction angle variably such that the conduction waveform per phase will be within 120 deg. in a conduction phase where magnets buried in the rotor of DC three-phase brushless motor perfectly face the field winding of stator at 0 deg. when the waveform is symmetric from -600 deg. to +60 deg. around 0 deg. and from +120 deg. to +240 deg. around +180 deg.. According to the arrangement, motor efficiency can be enhanced by decreasing the number of switching times of inverter 3 without varying the voltage amplitude.

Title: Misfire detecting device for gasoline engine
Inventor: MIYATA SHIGERU
IPC: G01M15/04
Filed: 1993-01-12
Abstract: PURPOSE:To perform reliable detection of the misfire of a gasoline engine even in instantaneous brake during the occurrence of a misfire, in detection of a voltage change between the electrodes of an ignition plug. CONSTITUTION:The passage of the peak value of a sensor 50 to detect a voltage between the electrodes of an ignition plug after spark discharge of the ignition plug is detected by a peak value passage detecting part 21. By releasing reset of a peak hold circuit 35 after a lapse of a given time starting from the detection, the output of the sensor 50 is held, a peak value held by a peak hold circuit 31 is compared with a voltage value held by the peak hold circuit 35. In a case of instantaneous brake during the occurrence of a misfire, since a voltage after the passage of a peak value is remarkably reduced compared with that during ignition, instantaneous brake during the occurrence of a misfire is detectable. Further, since, during the occurrence of a normal misfire, a voltage is slowly reduced, decision is practicable by means of a comparing circuit 38 based on the voltage of the peak hold circuit 35.

Abstract: PROBLEM TO BE SOLVED: To make the scale of a delay discriminator small and also to make a trace characteristic satisfactory.

On the other hand, a spread spectrum signal is inputted to a quasi-synchronous detection circuit 12 and applied quasi-synchronous detection, and an LPF 13 extracts a modulation band and inputs it to a delay discriminator 14. The discriminator 14 converts into a pattern that is the level only when a pattern converter 14b performs level change of the PN sequence, a multiplier 14a multiplies it by an inputted receiving signal, an ADC 14c samples the multiplication result through a clock that is delayed by 1/2 chip by a 1/2 delay circuit 14d, and an integrator 14e integrates and makes a delay discrimination output of a received signal.  A loop filter 15 converts it into a control signal and makes the PN sequence coincide with the time phase of a received signal by controlling an oscillation frequency of a clock oscillator 16.
