Filed: 1990-05-16
Abstract: PURPOSE:To obtain the subject substance in high selectivity by dispersing zinc oxide and/or zinc hydroxide in a dissolved state in the reaction system and carrying out reaction in partially hydrogenating a monocylic aromatic hydrocarbon in the presence of an Ru catalyst and providing a cycloolefin. CONSTITUTION:At least one kind of zinc oxide and zinc hydroxide is dispersed in a dissolved state in the reaction system and a monocyclic aromatic hydrocarbon (e.g. benzene or ethylbenzene) is partially hydrogenated in the presence of an Ru catalyst (e.g. Ru black, chloride or sulfate) to provide a cycloolefin. The zinc oxide or zinc hydroxide is added in an amount within the range of 0.001 to the saturated maximum amount based on the solvent used expressed in terms of atomic ratio of the zinc to the Ru used. It is necessary to carry out the aforementioned reaction in the solvent and water, an alcohol, etc., capable of dissolving the zinc oxide or zinc hydroxide in a high concentration are preferred as the solvent. Corrosion of containers will not occur by the above- mentioned method.

Title: Image converting system
Inventor: KATO TETSUO
IPC: G09G5/36
Filed: 1989-05-19
Abstract: PURPOSE:To prevent the occurrence of aliasing on an image boundary by reading out and allotting the corresponding image element data of an output image memory means to the image element data positioned at the outer part of an input screen out of four mapping image data positioned around respective image elements on an output screen. CONSTITUTION:When the image data positioned outside the input screen is addressed and read out from a mapping memory 3, a switch S for outputting the image data is switched by a controller 6. And then, the data which corresponds to the address (the image data equivalent to a background) is selected from an output image memory 10 and an interpolating operation is performed. Then, the data of the image element which becomes the boundary part on the output screen is obtained by performing the interpolating operation in which the image data which becomes the background and the converted image data are mixed. Thus, the data positioned at the boundary part of the converted image displayed on the output screen can become smooth and the aliasing which occurs on this part can be effectively removed.

Title: Level conversion circuit
Inventor: YOKOMIZO KOICHI
IPC: H03K19/0175
Filed: 1990-05-15
Abstract: PURPOSE:To attain level conversion without delay of an input signal by turning on/off a 1st MOS transistor(TR) based on a 3rd signal to control the conduction of a 1st bipolar TR and controlling the conduction of a 2nd bipolar TR based on a 4th signal. CONSTITUTION:An amplifier section 60 amplifies 1st and 2nd signals S1, S2 to a prescribed voltage level and outputs 3rd and 4th signals S3, S4, then a 1st MOS TR 71 is turned on/off based on a 3rd signal $3. A 1st bipolar TR 72 acts like pulling down an output of an output section 70 by using an output of the 1st MOS TR 71. Moreover, a 2nd bipolar TR 73 acts like pulling up an output of the output section 70 based on a 4th signal. Thus, number of logic stages from the amplifier section 60 till the 1st and 2nd bipolar TRs 72, 73 in the output section is decreased. Thus, the increase in the propagation delay time is avoided.

Title: Microprogram controller
Inventor: OGAWA HIROSHI
IPC: G06F9/38
Filed: 1983-07-07
Abstract: PURPOSE:To minimize the deterioration of performance of a microprogram controller when the branching prediction fails by restarting the execution after a machine cycle from read-out of a memory by a start address at a failure mode of branching prediction stored in an address register. CONSTITUTION:The outputs of address registers 1 and 4 are supplied to a selector 7; while the outputs of an address register 2 and a branching address register 3 are supplied to a selector 6. The output of a selector 8 is connected to control memories 9 and 10, a+1 adder 5 for microinstruction address and the register 4. A selector 11 outputs the selected microinstruction to a microinstruction reading register 12, the register 3 and a control register 15. A signal line 102 is set at logic ''1'' only when the present microinstruction is shifted to the next microinstruction. A signal line 101 is set at logic ''1'' together with the line 102 at a failure mode of branching prediction. The register 14 functions as a means which discontinues the execution of microinstruction for a machine cycle when logic ''1'' is set.

Title: Light emitting diode
Inventor: MORI MITSUHIRO
IPC: H01L33/14
Filed: 1982-07-19
Abstract: PURPOSE:To improve electric current density and luminous brightness by limiting size of the p-n junction using an etching groove and by p<+> and n<+> junctions which are formed by semiconductive layers of high impurity atom concentration. CONSTITUTION:A p type layer 12, an n type layer 15 and an n<+> layer 22 are continuously grown respectively on a GaAlAs substrate 11. The p-n junction is separated by the concentrically circular etching groove which reaches the p type layer 12. Outside the etching groove, selective diffusion of zinc is introduced outside the p-n junction into the depth of the p type layer 12 to convert it to p<+> layer 13 which is connected to an external unit through a p type ohmic electrode 19. The internal mesa is converted to p<+> layer 17 to an extent of entire n<+> layer 22 and of depth of a part of the n type layer 15 by another zinc diffusion process. The flowing passage for electric current is restricted to the central region of the element by making use of reverse bias characteristics of the p<+>-n and P<+>-n<+> junctions in order to restrict luminous radiation region. As a result of this, an element of low thermal resistance can be obtained by the layer 17 which is electrically isolated but remains thermally conductive, in other words, driving by large electric current becomes possible.
