Title: Illuminator
Inventor: TATSUOKA MASAMICHI
IPC: G03G15/04
Filed: 1982-02-01
Abstract: PURPOSE:To absorb heat rays and to prevent materials of members from overheating by arranging an optical filter which absorbs infrared rays close to visible light well between a lamp and an original surface, and correcting drum sensitivity. CONSTITUTION:A main reflecting mirror 2 having an elliptic surface is arranged around the lamp 1 and reflected light from the main reflecting mirror 2 illuminates a slit part 5 on the original surface 4 through a subordinate reflecting mirror 3. Luminous flux emitted from the lamp 1, while reflected by the main reflecting mirror 2 to converge, travels to the subordinate reflecting mirror 3 and is further reflected by the subordinate reflecting mirror 3 to form an image in front of the original surface 4, thereby illuminating the slit part 5 of the original surface 4 in the form of divergent luminous flux. The optical filter 6 which absorbs infrared rays and makes color correction is arranged between the main reflecting mirror 2 and subordinate reflecting mirror 3 slantingly to the optical axis connecting both reflecting mirrors together.

Title: Method and device using data bus as storage element
Inventor: NICHOLAS S FIDOSIA
IPC: G06F3/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To eliminate possibility that the error of transfer data occurs, to reduce the number of storage elements required for the synchronism of transfer between the inner logic of a data block and a bus and to reduce power consumption in a digital system. SOLUTION: For transferring data between the first data block 46 and the second data block 48, the first data block drives the respective conductors of the data bus 50 to a prescribed logic value and it becomes a high impedance mode. When the bus is in the high impedance mode, the memory storage element 52 related to the respective conductors of the data bus 50 holds the corresponding conductor to the logic level which is previously driven. While the bus conductor is held by the memory storage element, the first data block 46 becomes the high impedance mode and data is read from the data bus 50 by the second data block 48.

Title: Control system for lifetime of carrying pin in electronic component automatic mounting machine
Inventor: ITO TAKASHI
IPC: H05K13/04
Filed: 1988-01-26
Abstract: PURPOSE:To facilitate the maintenance of an automatic drive mounting machine while improving operating efficiency, and to enhance the productivity of a mounting board by detecting the posture of an electronic component being carried and previously determining a defective carrying pin. CONSTITUTION:A main control section 11 outputs an electronic-part intake command T2 to a part intake control section 12 on the basis of a carrying-pin number NP by a start command ST from a console panel 22 while outputting the posture check command T1 of an electronic component E to detection decision section 14. The detection decision section 14 checks coincidence with the assignment of a numerical control program of a posture detecting signal SF from an attitude detector 7, and outputs the result J of the decision and the carrying-pin number N to lifetime decision section 25. When a carrying pin at the position of the intake of the component is collated and decided to be a defective one, the component intake-operation stop command T2 is output to the part intake control section 12. Accordingly, the probability of the stopping of an automatic mounting machine is lowered, and the exchange period of the defective carrying pin can be determined easily by an operator, etc., thus improving the productivity of the mounting of the electronic parts.

Title: Electrostatic discharge protecting device having hetero-junction structure
Inventor: SAI SOUKUN
IPC: H01L21/822
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To achieve higher speed turning on of a parasitic bipolar transistor by providing a material layer with a potential lower than that of the silicon substrate in the silicon substrate between the source and the drain. SOLUTION: A material layer 50 with a potential lower than that of the silicon substrate 10 is formed in the silicon substrate 10 between the source 20 and the drain 30. This material layer 50 serves to collect holes from among electrons and holes generated by a strong electric field in the drain region produced by an electrostatic discharge pulse. Further, the material layer 50 is formed of a hetero-junction structure. Therefore, the material layer 50 has an energy gap smaller than that of the silicon forming the substrate 10 so that it can form a quantum well with a potential lower than that of the substrate 10 and it can rapidly drive a parasitic bipolar transistor because the electrons and holes of germanium have a large mobility. Thus, higher speed turning ON of the parasitic bipolar transistor can be achieved and a overcurrent can be prevented from flowing into the chip.

Filed: 1988-01-28
Abstract: PURPOSE:To enable highly accurate measurement with a simple construction, by arranging two targets with a specified radiation intensity in an infrared rays region, the one at a far distance and the other at a close distance separately. CONSTITUTION:Two targets with a specified radiation intensity are arranged in an infrared rays area, the one, heat plates 21 at a far distance and the other, heat plates 22 at a close distance separately and the apparent size of the heat plates 21 and 22 is set the same as viewed from an infrared rays video device 23 to obtain video signals S1 and S2 and S10 and S20. In operation, the heat plates 21 and 22 with the temperatures T1 and T2 and T10 and T20 arranged at two points, far and close, are observed with the device 23 to determine video signal intensities per unit temperature of the heat plates by a first specified formula from video signal intensities S1 and S2 obtained when a scan line crosses over a pair of heat plates 21 and signal intensities S10 and S20 obtained when the same scan line scans a pair of heat plates 22.

Title: Impurity doping
Inventor: HONMA YOSHIKAZU
IPC: H01L21/316
Filed: 1989-01-27
Abstract: PURPOSE:To enable doping an oxide thin film with an impurity with a simple process and at a low temperature by forming a thin film of a doping element on the surface of an unoxidized base material substrate and applying oxygen ion beams to or performing plasma oxidation of said substrate for utilizing an ion beam induction-diffusion phenomenon. CONSTITUTION:A thin film of a doping element is formed on a base material substrate by deposition, sputtering, or other methods. Oxygen ions (e.g. O2<+>, O<+>, and O<->) are applied to the base material substrate on which the thin film of a doping element is formed. In application of the oxygen ions, the thin film of a doping element formed on the surface of the substrate is removed by sputtering, however, a part of the doping element diffuses into an oxide film with the progress of oxidation of the substrate. This diffusion is caused by ion beam induction, therefore, a high diffusion speed can be obtained without heating the substrate to a high temperature and the doping element diffuses in the whole thickness of the oxide film. Thereby an oxide thin film can be formed simultaneously with doping with an impurity and the doping with an impurity can be performed with a simple process and at a low temperature.
