Title: Magnetic video recording and reproducing device
Inventor: BABA KENJI
IPC: H04N9/87
Filed: 1980-07-11
Abstract: PURPOSE:To stabilize instantly the time axis of a reproduced color signal which is fluctuating in the time axis, by providing a magnetic video recording and reproducing device with a circuit which detects the discontinuation of time intervals of a horizontal synchronizing signal and by controlling the variable frequency oscillator of a color AFC circuit. CONSTITUTION:A luminance signal in a color video signal reproduced by a video head 11 is extracted as a horizontal synchronizing signal by using an FM modulator 12 and a synchronous separating circuit 13 and supplied to an AFC circuit. This circuit consists of an AFC detecting circuit 14, a variable frequency oscillator 15, a 1/4 frequency dividing circuit 16, and a 1/40 frequency dividing circuit 17 and controls the oscillation frequency of the oscillator 15 by using the output of a detecting circuit 19 for the discontinuation of the horizontal synchronizing signal connected to the circuit 13, thereby preventing the defective acquisition of synchronism of the AFC circuit. In the AFC circuit, on the other hand, a reproduced burst signal from a burst gate circuit 21 is supplied to an AFC detecting circuit 22 to be compared with the signal of a color reference oscillator 23 in terms of phase, and a voltage which corresponds to the phase difference is applied to the 2nd variable frequency oscillator 24 to be supplied to a frequency converter 20 while following up the phase of an oscillator 23.

Title: Apparatus for detecting flaw of coated film on metal material
Inventor: KIHIRA HIROSHI
IPC: G01N27/416
Filed: 1984-05-15
Abstract: PURPOSE:To detect the flaw of the coated film on a heavy corrosion-proof steel pipe, by a method wherein the opening part of a detector is closely contacted with ametal member having a coated film and an electrolyte is held in the detector and an electrolytic current is generated between the metal member and the electrode of the detector. CONSTITUTION:The opening part of a detector 3 is made of rubber and closely contacted with a steel sheet pile 8 while an electrolyte is held in the detector 3. An electrolytic electrode 2 is provided in the detector 3 and connected to a power source 6 by a lead wire 4. When there is a flaw in the paint film 7 of the steel sheet pipe 8, a current is flowed between the steel sheet pipe 8 and the electrolytic electrode 2 and detected by a current measuring instrument 5. However, when there is no flaw in the coated film 7, no current is flowed. Because the detector having the electrode held therein is closely contacted with the steel sheet pipe to detect the electrolytic current, the flaw of the coated film of a heavy corrosion-proof steel structures installed in harbors and lays can be easily detected.

Title: Controller for shuttle printer
Inventor: ISHII SHOZO
IPC: B41J2/515
Filed: 1987-04-17
Abstract: PURPOSE:To surely discriminate the moving direction of a hammer bank even when a sensor has an ageing change, or a mechanical encoder disc has a mounting error, by measuring the width of a slit signal, and determining the period of pulses to be measured from a measured result. CONSTITUTION:The values converted from the width of a slit into times are T1 and T2 (T2<T1<3XT2) as T1 and T2 slits. A counter 10 adds a clock pulse CLK from its load value each time a slit signal is generated and a carry signal is generated, and generates a carry signal each time a period value is counted. Accordingly, pulses to be measured, i.e., the carry signals of the counter 10 are generated twice at the time of the T1 slit, and the pulses are generated once at the time of T2 slit. Thus, an AND gate 18 generates a print start signal, i.e., a left end print start signal at the time of going passage at the falling timing of the T2 slit, and an AND gate 20 generates a print start signal, i.e., a right end print start signal at the returning passage at the falling timing of the T1 slit.

Title: Recovery of azeotropic agent in production of aminoalkyl (meth)acrylate
Inventor: KIMURA MASAHIRO
IPC: C07C213/06
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To efficiently recover an azeotropic agent by improving two layer- separating property of azeotropic mixture comprising methanol produced as a by-product in reaction and the azeotropic agent in production of an aminoalkyl (meth)acrylate. SOLUTION: In producing an aminoalkyl (meth)acrylate by transesterification of methyl (meth)acrylate with an aminoalkyl alcohol, an azeotropic mixture comprising methanol and an azeotropic agent is distilled away from a reactor 1 and the azeotropic mixture is cooled to separate methanol layer from an azeotropic agent layer in a separator 6. An amine compound is absorbed and removed from the methanol layer liquid in an ion absorber 7 and the azeotropic agent is recovered from the amine removing liquid and recycled. Since good two-layer separating property is obtained at a temperature near ordinary temperature by keeping an amine compound concentration in the separator 6 low, the method is advantageous in energy aspect. The ion absorber 7 may be provided in a pipe 51, a pipe 61 or a pipe 91.

Title: Seal device for drilling direction control part of drilling machine
Inventor: IKEDA AKIO
IPC: E21B7/08
Filed: 1995-03-28
Abstract: PURPOSE: To improve sealing property by providing a pressure equalizing mechanism between muddy water and lubricating oil on a shaft of the upper part of a universal joint, and flexibly connecting a seal box provided on a lower shaft to a housing. CONSTITUTION: When lubricating oil 44 enclosed in a cylindrical housing 6 is expanded by high temperature at a bottom hole so as to become higher pressure than muddy water 45, the lubricating oil flows from a communicating hole 43 into a bladder 41. Next, the bladder 41 is expanded outward, and the expansion is stopped when the pressure is equalized. Next, when the muddy water 45 becomes higher pressure than the lubricating oil 44, the lubricating oil 44 flows out of the bladder 41 through the hole 43, and the contraction of the bladder 41 is stopped when the pressure is equalized to that of the muddy water 45. Further, when a lower rotary shaft 2 is bent against the housing 6, a lower seal device 7 is rotated centering around the center of a spherical part A.  In this case, a projecting face member 24, the shaft 2, and a mechanical seal 25 are held in parallel with each other, and hence the function of the seal 25 is ensured, Hereby, leakage of lubricating oil and invasion of muddy water can be prevented.

Title: Conical beam linear array antenna for mobile satellite communication
Inventor: TAKAHASHI KOUZOU
IPC: H01Q19/28
Filed: 1981-06-23
Abstract: PURPOSE:To remove a driving means for an antenna by using a conical beam having a conical radiating pattern constituted by a power supply element and a  wave director. CONSTITUTION:One shaft is provided with a power supply element 1 constituted as a turn style antenna and a reflector 2 consisting of an electric conductor plane sufficiently larger than the wavelength. In addition, a wave director 3 is attached to the front of the power supply element 1. Consequently, the gain of about 8dB is obtained in the direction of 45 deg. from the shaft. The directional pattern is made conical shape and is nondirectional in a horizontal plane. When said antenna is mounted on a moving element, the wave angle of a satellite observed from the moving element is not suddenly changed so that a tracking means is unnecessary. Moreover, the relation between the wave angle and gain can be simply changed by changing the interval between elements.

IPC: H03K17/78
Filed: 1991-04-03
Abstract: PURPOSE:To obtain a sensor output with high accuracy even when the disturbing light changing with a high frequency is present. CONSTITUTION:A light emitting diode 11 is driven by a drive signal of a drive circuit 10. The drive signal has the pulse width not smaller than half the cycle of the periodically changing disturbing light. A photodetecting signal output from a photodiode 21 is latched by a latch circuit 24 and shifted by a shift register 25. Only when the photodetecting signal exceeds the level of a threshold value of a comparator 23 when all the latch pulses are output, an H level signal is generated from an AND circuit 26. Accordingly, an erroneous detection is prevented.
