Title: Antenna for receiving radio waves for broadcasting from satellite
Inventor: MISHIMA NOBORU
IPC: H01Q23/00
Filed: 1992-09-08
Abstract: PURPOSE:To miniaturize the antenna, to decrease the number of parts and to reduce cost by providing a horn-shaped radio wave catcher and fitting a converter to the base end part of the radio wave catcher. CONSTITUTION:A converter 20 is fitted to the base end part of a radio wave catcher 10. The center of the converter 20 is made coincident on the center of the radio wave catcher 10. A pedestal 30 supports the radio wave catcher 10 near the centroid position of this catcher and can control the elevation angle and azimuth angle of the radio wave catcher 10. The radio wave catcher 10 of this antenna is corn-shaped and shows high prescribed efficiency by setting the inclining angle to the center axis at a prescribed angle. Therefore, the diameter of the head of the radio wave catcher 10 can be reduced to a prescribed length. At such a time, the radio wave catcher 10 near the centroid is stably supported by the pedestal 30 although the length of the radio wave catcher 10 is turned to a prescribed length and made thicker than the thickness of a dish-shaped radio wave catcher.

Title: Method and apparatus for color separation
Inventor: MARUKU MAAI
IPC: G06T7/00
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide stable color reproduction by selecting coloring materials so that a color change in respective individual colors or series of colors can be preferentially reduced as much as possible concerning the change or fluctuation of the parameter. SOLUTION: The solution of Neugebauer equation for prescribed values X-Z looks as the cross section among three surfaces corresponding to these values, and a cmy process is presented. An axis turning to right corresponds to yellow (y), an axis turning to the left corresponds to magenta (m) and an axis turning upward corresponds to cyan (c). Corresponding to (n) ink processes, (n-3) coloring material values are sampled for 0%-100%, for example. The extracted ink process is decided out of (n) ink processes by setting the (n-3) coloring materials to sampling values. Three extracted ink processes are inverted and stable numbers are calculated corresponding to respective solutions in a coloring material domain. This procedure is repeated for all the sampling values of (n-3) coloring materials and the combination of coloring materials having the minimum stability is kept.

Title: Power failure detecting circuit
Inventor: YONEKURA MIKIO
IPC: G01R19/165
Filed: 1987-10-22
Abstract: PURPOSE:To improve resistance to noise by controlling a timer time constant according to the charging quantity of an input capacitor in a power unit. CONSTITUTION:When it is assumed that a power failure state is entered and an AC power source input Vac is broken, the voltage Vrec obtained by rectifying the input Vac on a full-wave basis is also broken. When the Vrec falls below the threshold value Vsca of a comparator, the output Vco of the comparator Comp 1 goes up to a high level to change the capacitor Ct of a timer circuit from a charged state to a dischargeable state, so that the voltage Vct of the capacitor Ct beings to rise. Further, when the output Vco goes up to the high level, an analog switch AN is opened to disconnect the capacitor Ct from the output of an amplifier (Amp) 1, a voltage K1.Vci proportional to the voltage across an input capacitor Ci is held, and K1.K2.Kic obtained by multiplying said voltage by the amplification factor K2 of the amplifier 2 is held and outputted from the amplifier Amp 2, so that this value is the charging time constant T0 of the capacitor Ct. Then when the voltage Vct of the capacitor Ct exceeds the threshold voltage Vscb of the comparator Comp 2, a power failure alarm signal is outputted.

In this case, a seal material 16 is drawn and peeled off from this side part so as to be drawn by a detaining shaft 13 and the wrapping shaft 15, and opening part 11a of a toner cartridge 10 is opened completely. In such a way, a toner in the toner cartridge is dropped surely into a prescribed position in a toner hopper 2.

Title: Method for molding module cover of air bag device
Inventor: ZUSHI TAKAYASU
IPC: B60R21/20
Filed: 1991-10-16
Abstract: PURPOSE:To demold a module cover without deforming the same in the molding of the module cover of an air bag device. CONSTITUTION:Upper and lower molds 16, 11 are clamped and a resin material is injected in the molds to mold a module cover 1.

Title: Method for adaptation decision of probe shape and method for measuring surface shape
Inventor: FUJII AKIKO
IPC: G01N37/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To decide a measurement area with good reliability by setting measured values of a rise angle, a fall angle of a standard sample which is too steep to be traced by a probe, as reference values of reliability failure, and comparing measured angle values of a measured sample with the reference values. SOLUTION: A standard sample 10 having a vertical rise, a vertical fall is scanned by a probe 13 of an atomic force microscope. A measurement locus 19 with a rise angle α, a fall angle βwhich cannot be measured because a measured shape at this time reflects a shape of the probe 13 is obtained. The angles α, β are stored as reference values. When a measued sample is scanned, a shape in which a part HI rises with an angle (X), a part LM rises with an angle α, a part JK falls with an angle βand a part NO falls with an angel (y) is obtained. The angles are compared with the reference values. Since the rise part LM is equal to the angle α and the fall part JK is equal to the angle β, the parts are judged to be not reliable. The other parts than the rise part LM and fall part JK are judged as an area measured with good reliability.

Title: Multi-path noise detector
Inventor: RYU TAKASHI
IPC: H04B17/00
Filed: 1987-10-23
Abstract: PURPOSE:To surely detect only multi-path noise by generating a rectangular wave signal with a proper time width when a peak of an input signal exceeds a reference value and counting and outputting the rectangular wave signal. CONSTITUTION:A high frequency component in an FM detection output fed to a terminal 5 is emphasized by an HPF 1 and an AGC amplifier 2 and fed to a pulse detector 3. The input to the detector 3 includes the multi-path noise and other noise, but since the white noise generated with a weak electric field strength is subject to gain control by the operation of the amplifier 2, the level does not reach the the reference value of the detector 3, then no output is caused. Pulse noise such as ignition noise of an automobile and the multi-path noise are detected by the detector 3 when the peak exceeds the reference value and the noise is converted into a rectangular wave signal with a proper time width. The rectangular wave signal is counted by a counter circuit 4, and when the count reaches a predetermined number within a prescribed time, a signal is outputted at a terminal 6.
