Title: Controller pwm converter
Inventor: SAKAI KEIJIRO
IPC: H02M7/219
Filed: 1995-02-01
Abstract: PURPOSE: To prevent the excess current at the time of starting a PWM converter by so controlling a converter input voltage vector as to reduce the difference voltage vector between the voltage vector of an AC power source and the input voltage vector of the converter when a diode rectifying mode is switched to a PWM control mode. CONSTITUTION: An AC power source is tuned ON in the state that a PWM signal is suppressed, and a smoothing capacitor is initially charged up to a diode rectifying diode. Thereafter, the output of the integrator 18b of a PI compensator 15a is always set to negative or a negative limit value by integrator output initializing means 23 until a converter start command 22 is output. Since the initial value of the integrator 18b is smaller than the output of a proportional gain 20b even if the effective power current command Iq* is positive, a q-axis voltage correct amount ΔVq becomes negative. Then, at the time of starting the converter, the converter input voltage is increased with the diode rectifying voltage of low DC voltage.  As a result, the difference voltage between the power source voltage and the converter input voltage becomes low, and an excess power source current does not flow.

IPC: H01L21/68
Filed: 1988-01-26
Abstract: PURPOSE:To enable a pattern to be registered with high precision independently of the thickness of a wafer, by arranging photomasks having marks thereon over a silicon wafer having at least two etching holes therethrough while the faces of the photomasks having the marks are opposed to each other, for registering the pattern. CONSTITUTION:Etching holes 8, 8 are formed in a wafer 7 while marks 11, 11 and 13, 13 are formed in photomasks 10 and 12, respectively, and, the etching holed 8, 8 are put in correspondence with the marks 11, 11 and 13, 13. It is determined which is larger in configurations the mark 11 or the etching hole 8, accoding to whether a pattern of the photomask 10 is black or transparent. The photomask 10 can be registered by means of a reflection-type microscope while it is irradiated with visible light from above. The same can be said for the marks 13, 13. Since the marks 11, 11 and surface apertures 9a, 9a are close to each other with a very small gap therebetween, they can be observed approximately in the same plate. In this manner, the pattern can be registered with high precision.

Title: Antenna system
Inventor: TSUNEKAWA KOICHI
IPC: H01Q1/24
Filed: 1994-02-09
Abstract: PURPOSE:To easily obtain high gain and broad band characteristic and to eliminate the effect of an installed object by employing a coaxial impedance converter to form a slot antenna. CONSTITUTION:In order to match the impedance of a feeder 24 with the antenna impedance when a 1/2 wavelength antenna element 21 fed from its lower end, the antenna system is provided with a coaxial impedance converter 22, the characteristic impedance of the feeder 24 is selected to be the geometric means of sets of the impedance and a 1/4 wavelength is selected for the length of the converter 22. Thus, the impedance of the converter 22 is matched with the impedance of the antenna element 21 by converting the impedance with the converter 22. On the other hand, a capacitor 29 is provided in resonance with the inductive component depending on the length of a slit 26 at an operating wavelength and an outer conductor 25 acts like the impedance converter with respect to the element 21, and the slit 26 acts like a slot antenna 27 and the space is shared in common. Since the converter 22 is broad in band and is not a matching circuit using a lumped constant, then the loss is small. Moreover, since a coaxial structure has a stub effect, the effect of other installed objects is less.

Title: Rotary type vaporization burner
Inventor: MATSUDA TAKAHIRO
IPC: F23D11/08
Filed: 1983-01-31
Abstract: PURPOSE:To prevent white smoke or offensive odor from occurring when a flame is put out, by providing means for spraying a liquid fuel dwelling in a premixing chamber over to a burning plate upper surface by blowing pressure. CONSTITUTION:When a vaporization cylinder 5 is heated by the heat of combustion, the liquid fuel that is dispersed along the inner surface is vaporized, and flows together with air into a gas collecting cylinder 7. While the vaporized gas and the air are mixed they flow from the gas collecting cylinder 7 into the premixing chamber 3, and spout from flame ports 2, and the mixture is ignited by a liquid drop burning flame to burn. However, since the gas collecting cylinder 7, an air blowing pipe 8, the premixing chamber 3, etc. are not heated well by liquid drop burning when it is in the cold season, the vaporized gas is liquefied again when it comes in contact with them, so that an oil sump is formed in the bottom of the premixing chamber 3. The dwelt liquid fuel is sucked through holes 12 by sucking action of Venturi sections 13 of spouting pipes 11 into spouting pipes 11, sprayed over the burning plate 1 and is burnt.

Title: Knee compressing/expanding circuit
Inventor: MATSUMURA TORU
IPC: H03M1/18
Filed: 1993-02-02
Abstract: PURPOSE:To comparatively easily mount the circuit on a one-chip digital signal processor and to contribute for miniaturizing a camera. CONSTITUTION:Preprocessing is performed to a signal from a solid-state image pickup device 1 by correlative duplex sampling 2 and after compression is performed by an analog knee circuit 3, analog/digital (A/D) conversion is performed by an A/D converter 4. Afterwards, broken line expansion is performed by a broken line expanding circuit 5, and corrected data stored in a look-up table 6 are added to broken line expanded data by an adder 7. A microcomputer 8 is used for controlling a knee level and an expansion level. Thus, since the data stored in the look-up table 6 are defied as difference between the inverse function of a knee compressing characteristic and a broken line expanding characteristic, capacity can be suppressed to input 7 bits and output 6 bits despite of conventionally requiring the capacity more than input 9 bits and output 10 bits.
