IPC: G06F17/50
Filed: 1989-01-23
Abstract: PURPOSE:To eliminate necessity to execute the manual edition of a rule application order file by automatically determining a rule application order so that a speed, the number of gates and the number of wirings can be made optimum. CONSTITUTION:A rule priority order determination part 12 determines the priority order of the rule in a conversion rule base 11 and stores the order to a rule application order file 13. When the order is designated with the speed as a reference, a circuit, for which a delay time is minimum, after the conversion or the rule having the block is selected out of the circuit, which is logically equivalent, after the conversion or the rule having the block. It is same for a case to designate the order with the number of the gates and the number of the wirings as the reference. A conversion processing part 14 applies the rule in the conversion rule base 11 to a pre-conversion circuit 15, which goes to be a conversion object, according to the order in the rule application order file 13 and outputs a post-conversion circuit 16. Thus, it is not necessary to manually correct the rule application order file.

Title: Stereoscopic electrophotographic method
Inventor: SAKAI TOSHIO
IPC: G03G15/22
Filed: 1980-02-08
Abstract: PURPOSE:To enable stereoscopic characteristic to be copied as well by so arranging the method that the photoreceptor is continuously exposed alternately by A-color light and B-color light with a microspace as a unit, making the polarities of the photoreceptor surface potentials in the exposed parts of the A-color light and the B-color light mutually opposite and visualizing these parts with the toners of two colors. CONSTITUTION:The photoconductive layers 1A, 1B of a photoreceptor 1 are charged in mutually opposite directions. More specifically, these are subjected to  primary charging of positive polarity under uniform irradiation of the B-color light,  then to the secondary charging of negative polarity in the dark, slightly less than the primary charging. In this state, electric double layers are formed double with opposite directions of dipole moment via the photoconductive layers 1A, 1B, so that the surface potential of the photoreceptor 1 of this time is made 0. If the A-color light and the B-color light are irradiated to the photoreceptor 1 of this time, the photoconductive layer 1A is made conductive in the part irradiated with the A- color light and the photoreceptor surface potential assumes negative polarity. In the part irradiated with the B-color light, the photoconductive layer 1B is made conductive and the photoreceptor surface assumes positive polarity.

Abstract: PURPOSE:To reduce a leakage current, to lengthen the holding time and to increase a noise margion by a method wherein a P-type channel-stop region is formed directly under a buried insulator region and an electrically insulated and isolated n-type diffused region is formed. CONSTITUTION:A partially buried insulator region 9 is formed with a thickness of about 350 nm at a depth of about 0.2 mu from the surface of silicon, e.g., by implanting ions of oxygen. After that, ions of boron are implanted, e.g., at an energy of 150-200 keV and at a dose amount of about 2 X 10<13>/cm<2> in such a way that the projected range is approximately equal to the base of the buried insulator region 9. After a heat treatment, the concentration of a p<+> channel-stop region 11 amounts to about 1 X 10<17> cm<-3>. It is desirable that this concentration is about 5 X 10<16>-5X10<17>/cm<3>. If the concentration is too high, breakdown strength in the reverse direction in relation to an n<+> diffused region is lowered. If the concentration is too low, the threshold value VTF of a parasitic MOS transistor is lowered and a leakage current becomes big.

Abstract: PROBLEM TO BE SOLVED: To prevent a top plate from rapid descending to prevent a desk from damages and a user from injury, by equipping a rotation resistant means to damp the rotation of the top plate in a foldable desk with the top plate pivotally attached to a support column and rotatable between a horizontal use condition and a folded storage condition. SOLUTION: When the top plate of this foldable desk is to be rotated from the vertical folded storage position to the horizontal use position, a damper main body 7 forming an oil room 10 to store a wing part 11 is rotated, centering on a rotation shaft 4 as shown by the arrow mark. At this time, since oil moves through an oil passage 10a from a part of the oil room to the other in a condition that a check valve 12 is closed, the rotation centering on the rotation shaft 4 is damped and performed under imparting rotation resistance to the top plate 1.  On the other hand, when the top plate is rotated from the horizontal use condition to the vertical folded storage condition, the damper main body 7 rotates to the wing part 11, but, since the check valve 12 is opened and then the major portion of oil moves by passing through the valve, no rotation resistance is given to quickly rotate the top plate.
