Title: Synchronizing signal detection circuit
Inventor: IKEGAMI KIYOSHI
IPC: H04J7/00
Filed: 1988-03-16
Abstract: PURPOSE:To reduce hardware and cost and to improve the stability of an action by constituting a title circuit in such a way that serial/parallel-converting input digital modulation signals into data of two sequences and a synchronizing signal detection pulse is outputted when the data is compared with a reference digital pattern and when the number of non-coincident bits is less than a threshold. CONSTITUTION:An input digital modulation signal A among two kinds of the digital modulation signals whose transmission rate is in the relation of two to one is serial/parallel converted by the clock signal fck having the same frequency as the transmission rate of the digital modulation signal whose transmission rate is higher. Thus, subsequent delay detection means 2 and 3 and a synchronous signal detection system can execute the signal processing not by the transmission rate of the input digital modulation signal but by using the fck/2 of the clock signal having the same frequency as the transmission rate of the digital modulation signal having the lower transmission rate. Thus, it is unnecessary to switch a clock reproducing system by the transmission rate of the input digital modulation signal, hardware and cost are reduced, and the stability of the action is improved.

Title: Faraday rotator integrated with polarizer
Inventor: SATO YASUSHI
IPC: G02B5/30
Filed: 1990-03-12
Abstract: PURPOSE:To eliminate the need for using a polarized beam splitter or the like and to obtain an extremely compact and inexpensive Faraday rotator by integral ly forming a diffraction grating at least on one end face of the Faraday rotator.

There by, the extremely compact and inexpensive Faraday rotor integrally with the polarizer canb e obtained without using an expensive PBS.

Title: Image pickup system
Inventor: TAKAYAMA SHIGEHIKO
IPC: H04N5/228
Filed: 1985-03-27
Abstract: PURPOSE:To suppress the occurrence of a false picture due to the return beam of an photo electric-type pickup tube and to improve remarkably picture quality by reducing the quantity of scan electron beams when a sensitivity upgrading switch is turned on at the time of photographing a low-illuminance subject. CONSTITUTION:A control voltage is given from a DC power source 13 so that the quantity of scan electron beams can be set as large as a few times a reference signal current. When the sensitivity upgrading switch 15 is turned on at the time of photographing the low-illuminance subject, a negative voltage is added to the DC power source 13 to decrease the control voltage, and the quantity of scan electron beams is reduced. The negative voltage is set to a value capable of controlling the quantity of scan electron beams so that a level difference in terms of contrast between the false picture due to the return beam and its peripheral picture can be eliminated. In this case the quantity of scan electron beams is set to a negative value controlling said quantity to 0.1muA. Thus the false picture due to the return beam of the pickup tube can be eliminated, and the picture quality can be substantially improved.

Filed: 1983-04-06
Abstract: PURPOSE:To improve the rate of correct reading by allowing an input pattern not to be collated with an unnecessary pattern at recognition based on the number of times where the input patterns are recognized correctly and in error respectively. CONSTITUTION:The number of times Y where the input pattern corresponding to each character pattern registered in a dictionary 4 are recognized correctly and the number of times N where the input patterns are recognized in error, are obtained in a managing table 8. When a device is used over a certain period, the character patterns of Y=0 among the character patterns registered in the dictionary 4 are regarded as not useful to the recognition. Further, the character patterns of Y<N are inadequate because of much erroneous recognition and these patterns are to be deleted from the dictionary 4. Especially, the character patterns of Y<N must be deleted from the dictionary 4 in order to improve the rate of correct reading by decreasing erroneous recognition.

Abstract: PROBLEM TO BE SOLVED: To efficiently cool a hydraulic fluid even by use of a cooling device with a small capacity by providing an accumulator for accumulating pressure oil exceeding the capacity of the cooling device on an inlet oil path of the cooling device. SOLUTION: A cooling device 14 for cooling a hydraulic fluid is disposed in a return oil path extending from a control valve 12 to an oil tank 11, and the capacity of the cooling device 14 is set smaller than the maximum discharge flow of a hydraulic cylinder S. An accumulator 17 for accumulating pressure oil is provided in an oil path extending from the control valve 12 to the cooling device 14, whereby when the discharge flow from the hydraulic cylinder S exceeds the capacity of the cooling device 14, the surplus can be accumulated in the accumulator 17. Therefore, the hydraulic fluid is discharged to pass through the cooling device 14 after the discharge flow of the hydraulic cylinder S is decreased, so that it can be efficiently cooled.  Thus, it will be sufficient to provide the cooling device 14 with a small capacity, which contributes to lowering of noise and compactness of the device.

Title: Method for detecting drop of stuck material in rh degassing vessel
Inventor: TOMITA YUSHI
IPC: C21C7/00
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To detect the dropping of stuck material such as metal or slag while catching CO concn. variation in exhaust gas by charging an aluminum for deoxidation into molten steel and detecting CO concn. contained in the exhaust gas after passing a prescribed time with a CO sensor, in the case of treating the aluminum-killed steel having carbon content of a specific value or higher in a degassing vessel. SOLUTION: The aluminum-killed steel having >=0.01 wt.% carbon content is treated in an RH degassing vessel. Desirably, this detecting method of the stuck material is the one, with which an alarm is sounded considering that the stuck material is dropped in the case of raising the variation of the CO concn. to >=3%/20 sec or in the case the passing time after charging the aluminum is the uniform mixing time or more of the RH degassing vessel. The aluminum is added into the molten steel, and successively, it is detected whether or not 1 min or more after charging the aluminum is passed as the time when CO is stabilized during deoxidizing the molten steel with the aluminum. Successively, in the case of passing 1 min or more, CO concn. is measured at each 10 sec and in the case of raising CO cocn. after 20 sec from the some point of time to >=3%, the alarm sounds so that it is recognized that the stuck material is dropped.
