Patent JP-H01233812-A (JP)
Title: Multi-stage amplifier for microwave
Inventor: SHIGAKI MASAFUMI
IPC: H03F3/60
Filed: 1988-03-14
Abstract: PURPOSE:To reduce number of elements of an oscillation prevention circuit by supplying a bias voltage to an input terminal of a transistor(TR) and providing a function of preventing oscillation to a short-stub applying matching and inserting the oscillation preventing resistor to the opposite side of the short- circuit face. CONSTITUTION:A function of preventing oscillation is provided to a short-stub 2 giving a bias voltage to the input terminal of the TR 1 and applying matching and the oscillation preventing resistor 3 is inserted to the opposite side of the short-circuit face. Since almost no current flows to the short-stub 2 supplying the bias voltage and applying matching, even when the oscillation preventing resistor 3 is inserted to the opposite side of the short-circuit face, no voltage drop exists and even when the constant is varied more or less to use the short- stub 2 with the oscillation preventing resistor 3 inserted thereto as the oscillation prevention, bias supply and matching, the characteristic is not affected by matching with a small change of the constant of other elements. Thus, the number of short-stubs and capacitors of the oscillation preventing circuit is reduced.

Title: Display control circuit
Inventor: IWATA ATSUSHI
IPC: G06F11/32
Filed: 1990-03-12
Abstract: PURPOSE:To display the performance of an arithmetic processor so as to recognize it in time series by detecting and holding the peak value of the arithmetic performance for the microtime sampled in time series and outputting the peak value as the data suited to the display in terms of time. CONSTITUTION:A register 21 is cleared in the timing of a sampling pulse, and the counted value of the register 21 is set to a register 22. Then a register 23 sends the counted value subjected to the addition or the subtraction of '1' in the timing of a display switching pulse to a display device. A comparison means decide four conditions, that is, the value of the register 21 is larger than that of the register 22(A), the value of the register 22 is equal to that of the register 23 (B), the value of the register 22 is larger than that of the register 23 (C), and the value of the register 22 is smaller than that of the register 23 respectively. Then the contents of the register 21 are set to the register 22 in the condition A or B. Then '1' is added to the contents of the register 23 in the condition C, and '1' is subtracted from the contents of the register 23 in the condition D. Thus, it is possible to visually recognize the performance of an arithmetic processor in time series.

Title: Knocking detecting apparatus for internal combustion engine
Inventor: WATANABE SATORU
IPC: G01H17/00
Filed: 1991-03-25
Abstract: PURPOSE:To prevent the deterioration of knocking detecting accuracy at the time of high speed operation of an engine. CONSTITUTION:When an engine-rotating speed N becomes faster, a sampling period  t is set at the shorter value (S2). In a frequency analyzing section (e.g. ATDC of 10 deg.-60 deg.) (a), the intensity of the specified frequency component which is extracted from the detected signal of a knock sensor is sampled for every sampling period  t (S3). Even if the engine rotating speed N becomes fast, the sampling intensity data whose number is approximately equal to that in low-speed rotation are sampled by the sampling of these intensity data. The occurrence of the knocking is detected based on a plurality of intensity data which are sampled in this analyzing section.

Title: Gyrotron device
Inventor: ITO YASUYUKI
IPC: H01J25/00
Filed: 1988-03-16
Abstract: PURPOSE:To expand oscillatable frequencies by operating a power source feeding the power to an electron gun so that the ratio between the voltage across a cathode and a control electrode and the voltage across the control electrode and an anode is changed when the power source is started. CONSTITUTION:A power source device is constituted of a DC power source 9, resistors 10 and 10' to divide the output voltage, a capacitor 12 connected in parallel, and a power source 11 to heat a cathode 5. Both ends of the resistor 10 are connected to an anode 7 and a control electrode 6, both ends of the resistor 10' are connected to the control electrode 6 and the cathode 5. In this case, the ratio between the voltage across the cathode of an electron gun used for an optical gyrotron and the cathode 5 and the voltage across the control voltage and the anode is increased timewise to the preset ratio, thus the spiral pitch coefficient of an electron beam rotated in the magnetic field alpha=nuV/nuP (nuV is the velocity of electrons in the vertical direction to lines of magnetic force and nuP is the velocity of electrons in the parallel direction with lines of magnetic force) is changed. Oscillatable frequencies can be thereby expanded.

Title: Photometry device
IPC: G03B7/099
Filed: 1992-03-17
Abstract: PURPOSE:To give precise exposure to the whole of the image frame of a film without exceeding the latitude range of the film when an object having large illuminance difference is photographed. CONSTITUTION:Illuminance for every division is measured by receiving light in each light receiving part 1 which is dividing a photometry part 6. By an arithmetic part 2, the illuminance of every division is changed to a shutter speed value and a diaphragm value and sent to a comparison part 3. By the comprison part 3, a part having the maximum illuminance is calculated and the liquid crystal part thereof is driven. The calculation is executed again through the light receiving part 1, the arithmetic part 2 and the comparison part 3 and an identical action is repeatedly executed until it becomes within the latitude range of the film. Thus, when the photographing is executed at a rear light time, a clear photograph can be taken even by a beginner without failure.
