Title: Method and device for machine-work
Inventor: MAAKU JIYOSEFU RAPURANTE
IPC: B23K26/02
Filed: 1990-09-19
Abstract: PURPOSE: To machine micro holes and other shapes accurately by scanning a low power beam and a high power beam combinedly, separating the optical path partially and positioning the high power beam after positioning the low power beam on a workpiece. CONSTITUTION: The machining device 1 combines a low power positioning test beam 26 and a high power machining beam 11 colinearly with a dichroic mirror 30. Then, the colinear combined beam 36 scans along the first axis 62 with a polygonal mirror 35, while a workpiece 55 is moved along the second axis 63 orthogonally crossing the first axis 62. In the meantime, from the optical path of the colinear combined beam 37, the low power beam is split off at least partially by a dichroic mirror 45. Then, the high power beam is positioned, after the place is decided where the high power beam impinges upon the workpiece 55 by means of the low power beam. Further, the device is equipped with a computer 65 and a strip photoelectric detector 60 for the purpose of testing the machining accuracy.

Title: Image forming method
Inventor: YAMAUCHI YASUKI
IPC: G03G15/01
Filed: 1994-10-13
Abstract: PURPOSE: To reproduce the color of the same density with small quantity of toner by performing development by using toner which is set so that image density to the toner of unit weight may be higher in a more succeeding stage. CONSTITUTION: In an image forming process for second and succeeding colors, a toner image is superimposed and formed on the toner image already formed on an image forming body, so that the potential of a toner layer already formed exerts an influence at the time of developing. Namely, even when exposure is performed on the same condition, the image potential obtained in the succeeding stage is lower than that obtained in a preceding stage. Then, the development is performed by using the toner which is set so that the image density to the toner of unit weight may be higher in the more succeeding stage in a toner image forming stage repeated plural times, and the image density to the toner of unit weight is corrected to become higher in the more succeeding stage.  It is desirable to change the content of a color material included in the toner as a means for correcting the image density to the toner of unit weight.

Filed: 1988-09-30
Abstract: PURPOSE:To highly maintain the frequency stability by converting the oscillation frequency of one side oscillating circuit to the compensation voltage responding to the temperature and controlling the oscillation frequency of other side oscillating circuit by the compensation voltage. CONSTITUTION:A constant temperature bath 8 accommodates first and second oscillating circuits 1 and 7, a circuit 1 AT-cuts a crystal oscillator 2, and the temperature characteristic is made into a cubic curved line and the temperature slope from the minimum value is made into  Appm/ deg.C. On the other hand, the circuit 7 makes a crystal oscillator 11 into a Y cut which is made into the linear curved line by the temperature characteristic. A frequency voltage converting circuit 9 converts the oscillation frequency of the circuit 7 to the compensation voltage and controls the capacity value of a variable capacity diode 10. The temperature characteristic of the circuit 7, since the temperature slope is steep, responds to the temperature in the bath 8 more sensitively than the circuit 1. Consequently, the micro frequency change due to the temperature change in the bath 8 of the circuit 1 is compensated and the oscillation frequency can be maintained to the high stability.

Abstract: PROBLEM TO BE SOLVED: To permit a big hit random number value not to be recognized from the outside so as to prevent an illegality by controlling a prize-winning signal issued at the time when a game ball wins a prize by means of a random number counter system using the random number value with respect to a main control substrate for controlling and indicating a 'big hit' situation. SOLUTION: When the game ball wins the prize in a first kind start prize winning port 4 formed on a game board surface, the value of a 'random number A counter' is stored in a memory at the prize winning point of time (S14). The stored value of the 'random number A counter' is used for extracting 'bit hit random number deciding table' judging values having the judging value of a 'big hit'. The values of each corresponding 'big hit random number deciding table' are set in the value of the 'random number A counter' and the values of the 'big hit random number deciding table' corresponding to the value are extracted at the time of storing the value of the 'random number A counter' in the memory (S16 and S17). The extracted value is used as the judging for judging whether the 'big hit' is the one in this time game or not.

Abstract: PURPOSE:To enable effective utilization of an internal capacity of a receiving coil by supporting deflection of a subject carrier base of a bed for MRI with a pin to reduce the volume of the carrier base. CONSTITUTION:A magnet 1 is provided and a magnetostatic field space 2 is generated with the magnet 1. A subject 3 lies on a second top board 4, a receiving coil 5 is provided wrapping the second top board 4 and the subject 3 from below a carrier base and a truck 7 with the receiving coil 5 thereon is provided in a space 6 under the second top board 4.

The receiving coil 5 is placed on the truck 7 and can move to a measuring part of the subject 3. When the subject 3 and the carrier base are wrapped in the finite internal capacity of the receiving coil 5, the volume of the carrier base is reduced to expand the selection of the subject 3. But any reduction in the volume of the carrier base causes shortage of strength to let the carrier base deflect and to prevent this deflection, the carrier base is supported with the pin 8 thereby allowing compensation for the insufficiency of the strength.
