Abstract: PURPOSE: To make visual field searching of a sample, measuring and storing of the structure of a sample image easy by arranging a means for continuously displaying the sample image during moving on a sample image display device, a driving control means of a sample stage, and a memory function. CONSTITUTION: Visual field searching of a sample 5 is conducted in such way that a sample stage 12 is moved with a sample stage driving control part 3, the moving state of the sample 5 is picked up as an image with a TV camera set in a main body 1, and displayed on a screen of a monitor 10. The state of visual field searching of the sample 5 is easily confirmed. During searching of the sample 5, move of the sample image is immediately stopped if necessary to measure the structure of the sample image. When the measured data is automatically recorded and stored with an image measuring device 14 serving as a memory function, since move of the sample image is automatically resumed within the range previously set, visual field searching of the sample, and measuring and storing of the structure of the sample image are easily conducted.

Title: Self-holding type solenoid and method for controlling the same
Inventor: KUMAZUKI KAZUHIRO
IPC: B41J9/24
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress an operation sound in terms of a self-holding type solenoid used in an image forming apparatus and the like. SOLUTION: Electric resistance values of an attracting coil 10 and a restoring coil 11 are set such that the relationship between an attracting force and a restoring force generated in the circumference of each of the coils is set to be (attracting force) > (restoring force). A current with a voltage of 24 V is allowed to flow in the attracting coil 10 and a current is allowed to flow in the restoring coil 11 at the same time, then a magnetic force is eliminated by the energizing of the restoring coil 11 so that the force for attracting a movable iron core is gradually reduced, thereby achieving a self-holding type solenoid having a small operation sound. The energizing time period applied to the restoring coil 11 is preferably 20 ms which is one third of the energizing time period, i.e., 60 ms applied to the attracting coil 10.

Title: Desorbing method for uranium and strontium
Inventor: FUKUNAGA TOSHIHIRO
IPC: C22B26/20
Filed: 1978-08-24
Abstract: PURPOSE:To allow U and Sr to be desorbed separately and efficiently at a great rate by contacting an adsorbent with U and Sr adsorbed to an aq. hydrochloric acid soln. of a specified pH to allow the Sr to be desorbed and by contacting the Sr-free adsorbent to an aq. carbonate soln. to allow the U to be desorbed. CONSTITUTION:An adsorbent with U and Sr adsorbed is contacted to an aq. hydrochloric acid soln. of pH 1-5 to allow the Sr to be desorbed. Next the Sr-free adsorbent is contacted to a 0.4-2mols/l circulating aq. soln. of a carbonate such as (NH4)2CO3, Na2CO3 or NaHCO3 to allow the U to be desorbed. Since deposits of Ca and Mg carbonates are removed in desorption of the Sr, the U desorption rate is increased to reduce the desorption time. After the U desorption the adsorbent has recovered adsorption power, and the adsorption-desorption cycle can be repeated smoothly.

Abstract: PURPOSE:To detect abnormal states in plural detection areas at a time by distributing and reflecting an electromagnetic or ultrasonic wave which is transmitted by a transmission part to respective reflection parts installed in the plural detection areas by a rotary reflecting body, and receiving it by a reception part. CONSTITUTION:A detecting device consists of the transmission part 1 which transmits an electromagnetic wave omega, plural reflection parts 2 which are installed in the plural detection areas and reflect the electromagnetic wave omega, the reception part 3 which receives the electromagnetic wave reflected by the reflection parts 2, the rotary reflecting body 4 which distributes and reflects the incident signal from the transmission part 1 to the reflection parts 2, and a detecting means 5 which compares the reception level of the electromagnetic wave omega reflected by the reflection parts 2 in the plural detection areas with a set level value to detect abnormality. Then, if abnormality occurs in one of plural detection areas and the electromagnetic wave omega changes in reflection direction at the reflection part 2, the light incident on the reception part 3 changes. Consequently, the electromagnetic wave omega at the reception part varies in reception level and the detecting means 5 detects the abnormality in the detection area.

Abstract: PURPOSE:To extract a stable change image and to eliminate an erroneous report and the missing of a report by providing a means which decides whether or not the mean value of the brightness level of a current image stored in a current image storage means and a deviation value calculated by a deviation value calculating means are within proper ranges. CONSTITUTION:The means value of the brightness level of current image data stored successively in the current image storage means 3 is calculated by a mean value calculating means 10 and the mean value decision means 11 decides whether or not illuminance is deficient. When this mean value is smaller than a value set by a parameter setting means 13, it is decided that the illuminance is deficient enough to cause malfunction. In this state, decision processing following a change image extracting means 7 is made ineffective to preclude the malfunction due to the deficiency in illuminance.

Filed: 1978-08-25
Abstract: PURPOSE: To dispense with a frequency compensation circuit and improve the rising property of a speed servo mechanism, by changing the locked position of the speed servo mechanism depending on a phase deviation signal.  
     CONSTITUTION: The phase differnce between a phase reference pulse on a terminal 102 and a pulse PGC on a terminal 100, namely, the pulse period of a flip- flop 108 is measured first by a counter 120. Then, the counter 120 generates an output MSD while intermediate clock pulses during  the period of a signal FF 21 are counted. A buffer counter 126 for a phase loop generates a signal MFD which is phase difference information, thereby changing an initial value for the count of a counter 78 for detecting the velocity of a speed loop. A flip-flop 70 for generating a frequency modulation output produces a pulse of width corresponding to the magnitude of phase and velocity terms.
