Title: Synthesis of substituted chlorobenzene
Inventor: KATAYAMA TATSUO
IPC: C07C25/18
Filed: 1991-06-03
Abstract: PURPOSE:To produce a substituted chlorobenzene in a high yield and in a high selectivity by reacting o-, m- or p-dichlorobenzene with a Grignard reagent in the presence of a palladium phosphine complex catalyst. CONSTITUTION:When dichlorobenzene of formula 2 is reacted with a Grignard reagent of formula 3 (R is alkyl or phenyl which may be substituted with an alkyl or alkoxy group; X' is halogen), a substituted chlorobenzene of formula 1 (e.g. p-chlorotoluene is obtained in the presence of a catalyst comprising a palladium phosphine complex of formula 4 [X is halogen; L is Ar2P-A-PAr2 (A is 2-5C alkylene, ferrocenyl; Ar is phenyl)] or a mixture of the compound of formula 4 with a didentate phosphine ligand [e.g. 1,3-bis(diphenylphosphine) propane]. The method permits to produce the compound of formula I from the inexpensive dichlorobenzene as a raw material and is therefore profitable.

Title: Method for calibrating array antenna
Inventor: MIURA TATSU
IPC: H01Q3/26
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain a coefficient that offsets the ununiformity of amplitude and phase which exists, except a prescribed excitation distribution of an antenna by performing a prescribed digital signal processing operation of a receiving signal output of each system, a receiving signal or plural receiving outputs which are acquired at the time of spatial discrete Fourier transform or an equivalent transform. SOLUTION: Ek (k=1 to 4) is a coefficient, which represents ununiformity of amplitude and phase of each system with a complex number. After a signal of each system from an antenna element 1 has been A/D converted, it is multiplied by a prescribed excitation amplitude coefficient ak (k=1 to 4) that performs appropriate side lobe control, etc. Next, the amplitude and phase for calibrating an array antenna are converted into a base band signal by a digital local oscillator 3, which can be controlled in each different system in a quasi-synchronous detector circuit 4.  A quasi-synchronous detection output signal, a high-frequency signal or an intermediate frequency signal is inputted to a maximum ratio synthesizing circuit 5, in order to detect a calibration coefficient that offsets the ek, based on a base band signal of each system, multiplied by a corresponding weight coefficient and then outputted.

Title: Crew protecting device for vehicle
Inventor: YAMADA TAKU
IPC: B60R21/01
Filed: 1980-11-07
Abstract: PURPOSE:To prevent false operation by operating an alarm and stopping the supply of power to an operating circuit which operates the crew protecting device when any abnormality of a preceding-stage circuit generating an operation signal for protecting the crew is found at the time of detection of collision. CONSTITUTION:When the collision of vehicles occurs, a coil 332 in a collision sensor 101 generates a voltage nearly proportional to the speed of the collision, and when the voltage exceeds the Zener voltage of the Zener diode 113 in the operating circuit 102, a currnt flows to the gate 118 of SCR 114 and turns it on. Accordingly, the current flows to a filament 115 to ignite an explosive not shown in the figure and thereby the protecting device such as an air-bag is operated. When there occurs the disconnection of the coil 332 in the device, the electric potential of a signal 119 and SCR120 in a diagnosing circuit 103 is turned on, whereby a fuse 116 is melted. Thus, by the voltage generated at both ends thereof, an alarming lamp 104 is lighted to inform the occurrence of abnormality, while, simultaneously, the operation of the operating circuit 102 is stopped.

Title: Non-linear optical directional coupler
Inventor: KOMATSU YOSHIRO
IPC: G02F1/37
Filed: 1988-06-24
Abstract: PURPOSE:To improve switching characteristic by forming an area consisting of semiconductor material having a wide band gap so that the width of the area is narrower than the space between two optical wave guides along the optical wave guides. CONSTITUTION:An AlGaAs buffer layer 101 and an AlGaAs clad layer 102 are grown on a GaAs substrate 100. In the wave guide layer between the two optical wave guides 110a and 110b on an incident side formed just under the edge of an Au strip 301 for impressing stress, an AlGaAs barrier part 109 having the band gap wider than that of GaAs, whose width is much narrower than the space between the optical wave guides, is formed along a light propagation direction in the almost middle of the optical wave guides 110a and 110b. Therefore, free carrier generated in one optical wave guide 110a does not diffuse to the other optical wave guide 110b. Thus, the mismatching quantity of phase larger than in the case that the AlGaAs barrier part 109 is not formed can be obtained and the switching characteristic can be improved.

Abstract: PURPOSE:To reduce a residual image and a baking, by scanning an effective scanning section of a target plane with an electron beam at a horizontal blanking period in a television camera using a photo conductive image pickup tube so as to increase the number of scanning in a prescribed time. CONSTITUTION:A sawtooth wave voltage having a vertical period is applied to a terminal 26 and a horizontal pulse where the level is at a high level at an effective scanning period Ha and at a low level at a horizontal blanking period Hr is applied to a terminal 27. Two inputs are added at an adder 29 to form a vertical stepped sawtooth wave voltage in the horizontal blanking period. This waveform is amplified at a positive amplifier 32 and an inverse amplifier 33, and led to a pair of vertical deflection electrodes of an electrostatic deflection image pickup tube from terminals 37, 38. A pulse height V4 at the horizontal blanking period is changed by changing the addition balance of the two signals at the adder 29 and the position on the target plane scanning the electron beam is changed between the horizontal blanking periods. That is, the scanning electron beam is returned to the next horizontal scanning start position during the horizontal blanking period while scanning the target plane finished with the reading scanning already.

This is processed and the command value of the sensor torch angle phi is emitted. A servo motor 10 is driven until the deviation between this and the detection value from an angle detector 11 becomes 0. This causes a gear 8 to rotate and the sensor 15 mounted to this to be turned so as to position always right above the weld line.

Title: Scanning method for image formed on color filter array film
Inventor: SHARMAN RICHARD ARTHUR
IPC: H04N1/04
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain an improved scanning system for photographic material by restricting the density range of an image forming layer so that respective colors in a color filter array may occupy individual parts, and dividing the dynamic range of a scanner. SOLUTION: The color filter array film is illuminated with light corresponding to the color of the color filter array. The density range of the emulsion layer of the CFA film is restricted so that it may occupy only a small part in the dynamic range of a monochrome scanner. The excessive dynamic range is used to distinguish the different colors of the color filter array. Especially, the density range of the scanner is divided to separate bands one by one concerning the recording of each color by the selection of the color or the filter action of scanner illumination. The scanner for the CFA film is selected to have the appropriate dynamic range, and the different colors of the color filter array are distinguished by the appropriate dynamic range.
