Title: Catalyst for aromatic halide isomerization and isomerizing method of aromatic halide
Inventor: NAKAJIMA MASANORI
IPC: C07B61/00
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To obtain a high activity catalyst for aromatic halide isomerization by making the half width in a specific value of interplanar spacing equal to or above a specific value in the X-ray diffraction pattern of the catalyst containing a zeolite having mordenite structure. SOLUTION: The catalyst for aromatic halide isomerization contains the zeolite having mordenite structure having the half width of 0.28 deg. in the interplanar spacing of d=0.346±0.005nm in the X-ray diffraction pattern of the zeolite. The zeolite is preferably acid type. And carrying silver or rhenium in the zeolite catalyst is effective to improve the isomerization activity of the aromatic halide. Further, introducing rhenium in the catalyst has the effect to suppress the deactivation of the catalyst due to coking. In such a case, it is also preferable to contain fluorine in the catalyst.

Filed: 1990-11-14
Abstract: PURPOSE:To set a modulation degree in the oscillation frequency of any channels to be fixed by providing additional circuits which correct the modulation degree to be fixed even if the oscillation frequency varies inside and outside VCO. CONSTITUTION:A variable capacitance diode for modulation CV2 which is different from that for oscillation frequency control is added to the inside part of a voltage control oscillator(VCO) 4 and a reverse bias voltage control circuit which impresses a voltage on the variable capacity diode for modulation CV2 controlled by a microcomputer 2 to the outside part of it.

Thus, the fixed modulation degree can be obtained in respective channels even in VCO 4 where the modulation sensitivity is unequal.

Filed: 1991-10-28
Abstract: PURPOSE:To eliminate the need of inputting a program in advance by detecting a sticker having a mark space stuck to an inner circumferential part of a disk in timing and performing reproducing after deleting music of a specified mark space number. CONSTITUTION:Reproducing unnecessitating music numbers marked in a mark space 7 in a prescribed position of the sticker 6 stuck to the inner circumferential part of the disk in a cartridge 2 are detected by a phototransistor 8. Subsequently, a data and a clock are separated via an amplifier 9 and a waveform shaper 10 by a data extracting circuit 11, and the clock is made to be an interruption input (a) to a CPU 3. Then, whenever reproducing is performed by the operator operating a key operation for selecting a track, whether or not the key input is coincident with a track number read out of the mark space 7 is discriminated, and only upon coincidence, the operation is shifted to a reproducing preparing operation. Consequently, it is not necessary to input a program in a compact disk player in advance, and reproducing music can simply be deleted.

Filed: 1989-11-29
Abstract: PURPOSE:To prevent wasteful gas outflow to improve breaking performance by eliminating a gap between a gas flow passage opening part and an exhaust guide with a spring provided on the exhaust guide, and electrically isolating the exhaust guide and a supporting base part. CONSTITUTION:Although an arc 4 is generated between a stator 3 and a needle 2 to heat a SF6 gas in a cylinder 5 in the initial stage of a breaking action, but the gas is not flowed out with an exhaust guide 19 closely sticked to an opening part 8 with a spring. The opening part 8 is extracted from the guide 19 at the point of time of the extraction of the stator 3 from an insulation nozzle, and a gas flow in both directions is concurrently produced to arc- extinguish the arc 4. Because the guide 19 is formed with an insulation material having an excellent heat resistance and slidableness, the damage does not to the contact part of the cylinder 5 and the guide 19. This prevents wasteful gas outflow at the time of heating and pressing to permit highly efficient breaking of large current.

Title: Radar system
Inventor: KITAZAWA HIRONORI
IPC: G01S7/32
Filed: 1994-12-12
Abstract: PURPOSE: To discriminate a bird group definitely from a target (vessel, rain cloud, land, etc.). CONSTITUTION: A Doppler frequency component DF having a predetermined bandwidth or above is extracted from Doppler frequency components DF extracted from a reflected signal VD through a Doppler filter 51 and it is regarded as a bird group. Since each bird flaps the wings, the Doppler frequency component DF has a predetermined bandwidth. On the other hand, the Dappler frequency component DF of a vessel is normally constant, and even if the vessel moves the Doppler frequency component DF is very low. Furthermore, the Doppler frequency component DF of wind cloud present in a relatively low sky and frequently mistaken for a bird group is constant or increases constantly. Since the Doppler frequency component DF related to a land depends upon the speed of a host vessel, it can be removed easily.  Consequently, a target including a Doppler frequency component DF having a predetermined bandwidth or above can be regarded as a bird group.
