Title: Display device
Inventor: NAGUMO FUMIO
IPC: G01R33/02
Filed: 1981-09-09
Abstract: PURPOSE:To execute display of a zebra pattern by a simple constitution, by displaying a level of a digital signal when a prescribed host bit has coincided with a specific code, in a device which has digitized a video signal. CONSTITUTION:Prescribed host 5 bits in a luminance signal Y among, for instance, 8 bits which is supplied to a terminal 1 are supplied to a code detecting circuit 11, and whether they coincide with a prescribed code or not is decided. In case of coincidence, its bits y3, y4 are converted to codes y3', y4' of bits decided in advance, of a digital signal, by a code converting circuit 12. Subsequently, among 8 bits of the luminance signal Y, a signal of y3', y4' are substituted for the bits y3, y4, and are outputted from a terminal 8. Accordingly, even in case of a device which is digitized a video signal, display of a zebra pattern can be executed.

Title: Method for recovering rhodium
Inventor: INOUE KATSUTOSHI
IPC: C22B11/00
Filed: 1990-05-31
Abstract: PURPOSE:To recover expensive rhodium by bringing a rhodium-contg. soln. into contact with chitosan made insoluble in acid and selectively adsorbing rhodium. CONSTITUTION:A rhodium-contg. soln. such as sulfuric acid and phosphoric acid is acidified with hydrochloric acid, in which a chlorine gas is blown to convert rhodium into a chloride complex. This soln. is brought into contact with chitosan made insoluble in acid by using a cross linking agent such as epichlorohydrin to selectively adsorb rhodium into chitosan. At this time, the concn. of hydrochloric acid in the rhodium-contg. soln. is regulated to 0.3 to 3.5 normality. Next, the chitosan adsorbed rhodium is subjected to heating treatment at >=400 deg.C and is incinerated, by which rhodium is recovered as a partially oxidized metal.

Title: Numerical controller
Inventor: KITANI NOBUYUKI
IPC: G05D3/12
Filed: 1990-05-31
Abstract: PURPOSE:To make it possible to use the numerical controller even for a machine in which a ball screw has odd pitches by setting up the ratio of a detected multiplier as a fraction. CONSTITUTION: When the weight of a distribution pulse from a processor 11 is set up to 1mum e.g. without using a command multiplier and the ball screw 34 has odd pitches, the detecting multiplier 21 applies the weight of 1mum to a feedback pulse. Namely, the multiplier 21 is expressed by a fraction. A reference counter 19 for counting up distribution pulses in each revolution of the ball screw 34 can be also optionally set up in accordance with the pitches of the screw 34. Since the multiplier 21 is specified by the fraction, a machine tool having a ball screw with odd pitches can also be controlled.

Title: Multistage magnetic fluid sealing device for vacuum space
Inventor: MATSUNAGA SHIGEKI
IPC: F16J15/43
Filed: 1991-05-20
Abstract: PURPOSE:To prevent a splash of magnetic fluid from scattering in a vacuum space without fail. CONSTITUTION:The right side is a vacuum space in this case. A magnetic fluid sealing device body 3a being opposed to this vacuum space holds a permanent magnet 7 between a pair of pole pieces 8a and 9a. An inner diameter of the pole piece 8a at the vacuum space side is smaller than that of another pole piece 9a. A space 19b at the opposite side to the vacuum space in holding the magnetic fluid sealing device body 3a between is leading to a vacuum pump 2. When air in a space 19a lying between these paired pole pieces 8a and 9a is expanded, a magnetic fluid 10 at an inner circumferential edge of the pole piece 9a is bursting, thereby preventing a pressure rise in this space 19a from occurring.

Title: Computation of optical spectrum
Inventor: IWASAKI TAKASHI
IPC: G01J3/28
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for computing optical spectrum that can obtain an optical spectrum of an arbitrarily determined wavelength bandwidth even in a spectroscope, wherein the width of an emitting slit cannot be arbitrarily changed. SOLUTION: In a wavelength bandwidth memory part 40, the characteristics of the bandwidth of the passing wavelength with respect to the measured wavelength of a spectroscope 5' are stored. A CPU 34 obtains the wavelength bandwidth for each measuring point based on the stored wavelength bandwidth. Then, from the measured value of the optical intensity at each measuring point, the measured values before and after with the measured value as the center are added over the range of the intended wavelength bandwidth. Furthermore, the value is corrected based on the ratio between the wavelength bandwidth at each measuring point and the wavelength interval at each measuring point. Thus, the optical intensity value at each measuring point is computed.

Abstract: PROBLEM TO BE SOLVED: To prevent malfunction caused by opening and closing of a door while the nip detecting sensitivity is kept high by keeping a threshold when the door of a car is in the open state without learning the threshold in automatically updating a threshold of nip detection by a learning system. SOLUTION: A microcomputer 20 stores a threshold for nip detection by each operation position of a window, and compares the threshold corresponding to the operating position of the window at that time with an actual value or the like of a motor current with a designated sampling period to instantaneously reverse a motor forcibly regardless of the operating condition of the operation switch, thereby opening the window when the actual value exceeds the threshold. When the door is closed by the operation of a door switch 33, the threshold of nip detection is learned and designated weighting amount is added to the actual value of the motor current at that time. The addition result is stored as an updated new threshold of the window position at that time.

IPC: G03F7/30
Filed: 1991-06-14
Abstract: PURPOSE:To treat a waste liquid while preventing the stagnation of development scum around a discharge pipe and admitting the development scum smoothly into the discharge pipe. CONSTITUTION:An oscillator 178 is mounted on an overflow pipe 70 and the frequency to be oscillated by the signal from an oscillator 19 is 10 to 300Hz. The amplitude near the aperture of the overflow pipe 70 when the overflow pipe 70 is vibrated by a vibrator 178 is 0.5 to 1mm amplitude and the development scum 18A is prevented from stagnating near the top end of the overflow pipe 70. A projecting part 182 projected radially from the peripheral surface of the overflow pipe 70 is supported by an eccentric cam 184. The overflow pipe 70 is moved (2mm) vertically for 0.5 second when the eccentric cam 184 rotates. The difference between the top end of the overflow pipe 70 and the liquid level increases when the projecting part 182 exists at the lowermost end. The velocity of flow of the developing water falling into the overflow pipe 70 is thus increased.

Title: Method and apparatus for radio identification and tracking
Inventor: ROBAATO ESU REISU
IPC: G06K7/00
Filed: 1991-06-14
Abstract: PURPOSE: To provide a method and a device for identifying items and tracking them, by adding a radio transceiver tag on the item and sending a signal between the tag and one or more interrogator sub-systems. CONSTITUTION: A tag is usually set under a low power stand-by mode unless a signal is sent by an interrogator. The interrogator carries the signal to all the tags within the receiving range, and the tag responds to it after a false random lag. When the interrogator identifies the tag, it returns the fact to the tag and the tag returns to the stand-by mode. The tag which is not identified by the interrogator sends the identifying signal again, and the process continues until all the tags within the range of the interrogator are identified.
