Title: Rapid measurement of mass spectrum
Inventor: KOU FUKUZEN
IPC: G01N27/62
Filed: 1979-09-06
Abstract: PURPOSE:To improve the rapidness and accuracy of measurement by preventing an ion current with signals generated on skipping of sweep and needless ion current during skipping from being input to a small current amplifier. CONSTITUTION:A sweep signal from a sweep signal generator I is input to a sweep controlling circuit F to change an electric field or a magnetic field in a mass spectrograph analysis space. On the other hand, ion signals generated in flip-flop of the sweep signal generator I during a skip-period of sweeping are applied to an ion source controlling circuit E as ion current preventing signals. Thus, a needless ion current during skipping is prevented from being input to a small current amplifier D which would amplify the ion current.

Title: Inverted siphoning method for river or the like in vacuum waste collecting system
Inventor: SATO MASAYUKI
IPC: E03F5/22
Filed: 1994-04-28
Abstract: PURPOSE:To reduce a lift loss as well as to widen a collectable range by installing an inverted siphoning part in the point midway in a vacuum duct, detecting a water level in this inverted siphoning part, and when it becomes more than the set value, inducing the atmosphere from a vacuum valve installed at the upstream side of this inverted siphoning part and drawing in waste water in the inverted siphoning part to the downstream side by vacuum suction. CONSTITUTION:An inverted siphoning part 34 of height difference H is formed in the point midway in the route of a vacuum duct 14 ranging from a terminal house-inlet unit 18 to a catchment tank 12 of a vacuum pump field 10, and thereby a horizontal crossing duct 38 and a riser piping part 40 are interconnected to each other. When waste water is collected in this inverted siphoning part 34, another waste water in a level equal to the former is stored in a level detecting vessel 42. Therefore a level of collected water into the inverted siphoning part 34 is made detectable in this way. In addition, when a vacuum valve 46 is attached and therefore the water level comes to a state of h<H, it is selected to the atmospheric side, utilizing negative pressure in the vacuum duct 14, the atmosphere is inhaled, and thus the waste water in the inverted siphoning part 34 is discharged to the outside. With this constitution, the extent of lift loss in the inverted siphoning part is reduced and a collectable range of the waste water can be widened.

Abstract: PURPOSE: To obtain an input device where limitation of original is small and operation is simple, by storing the output level of a light receiving element array for every element and stopping the storage operation by the detection output of deviation which is obtained by correcting the output level for every element.  
     CONSTITUTION: Under a state where initial data dependent upon a standard white original, etc., is written in memory 17, the output level for each light receiving element is subjected to irregularity correction on a basis of data in memory 17. When a original to be read is transferred, corrected picture signals are obtained as the output of amplifier 14. Then, it is detected whether the deviation of picture signals is larger than a normal value or not in deviation detection circuit 21; and if it is smaller than the normal value, the part of the original is fetched into memory 17 as available correction data. If it is larger than the normal value, it is stopped to fetch the part of the original into memory 17 as unavailable correction data, and latest available correction data is used as correction data for this original.

Title: Discharge lamp lighting circuit
Inventor: FURUKAWA YOSHIYUKI
IPC: H05B41/24
Filed: 1988-05-13
Abstract: PURPOSE:To conduct a DC firm preheating by feeding a preheating current of a discharge lamp directly from a power source to the filament of the discharge lamp through a current control circuit and a reverse-current preventing element. CONSTITUTION:When a power switch 1 is turned on, a preheating current of a discharge lamp 11 is sent from a current control circuit 7 to a reverse-current preventing diode 10, the filament of the discharge lamp 11, and a short-circuit preventing diode 12, as a relay contact 501 is on the side of a. Then, by turning a lighting switch 2 on, a transistor 4 is operated to excite a relay 5, and the relay contact 501 is changed from the side of a to the side of b. Therefore, a lighting circuit 8 is operated to generate a high frequency voltage, lighting the discharge lamp 11. At this time, the reverse-current preventing diode 10 prevents the high frequency voltage from applying to the current control circuit 7 or the relay contact 501. The high frequency voltage is fed to the discharge lamp 11 without being short-circuited by the diode 12. Hence, a DC firm preheating can be achieved.

Title: Method for improving bar stripping capability in restrained mandrel mill
Inventor: ODA TATSUHARU
IPC: B21B17/02
Filed: 1988-05-11
Abstract: PURPOSE:To reduce a tension acting on a shell and to improve the stripping capability by evaluating stripping capability of a mandrel bar during rolling by a mandrel mill and controlling a tension between the mandrel mill and a sizer based on the evaluated stripping capability. CONSTITUTION:A tension after finish of rolling by a mandrel mill is estimated by measuring a tension before finish of the rolling. Therefore, an allowable limit of a tension acting on a shell 3 before finish of rolling by a mandrel mill is set and an unusual situation is decided when a tension exceeds the limit. Thus, the stripping capability of a mandrel bar 4 is improved by controlling rolling speeds of a mandrel mill 1 or a sizer 2 to bring a tension acting on the shell 3 not to exceed the allowable limit when an unusual situation is recognized during rolling by the mill 1.

Title: Magnetic erasing device
Inventor: AOKI AKIRA
IPC: H04N9/29
Filed: 1986-05-20
Abstract: PURPOSE:To perform the magnetic erasing without turning on and off a power source switch by conducting a magnetic erasing current through a magnetic erasing coil at every constant time within a vertical blanking time to erase the magnetism. CONSTITUTION:A vertical blanking voltage V3 is applied to the base of a transistor TR4 and a timer output voltage V4 is applied to an emitter, respectively. The transistor TR4, only when the two types of the voltages V3, V4 are applied, is turned on, at the same time, a transistor TR5 is also turned on, and the magnetic erasing current is conducted through the magnetic erasing coil 6 from a charging circuit 4. When the generating period T7 of the timer output voltage is the period obtained by adding the period twice the vertical blanking period T6 to a vertical scanning period T5 or longer than it, the magnetic erasing operation can be effectively completed. Thereby, the magnetic erasing can be executed without turning on and off the power source switch.
