IPC: A61B3/06
Filed: 1990-04-24
Abstract: PURPOSE:To detect the degree of fatigue, especially, mental fatigue with high sensitivity by detecting a process in which a person to be examined selects a target by his own information processing function, from various angles by a focusing reaction of an eye. CONSTITUTION:Two pieces of measuring infrared ray light sources 9, 9' are placed at a suitable interval from the retina 1 of a person to be examined, and two beams A, B emitted from each of them irradiate an eye of the person to be examined, while reducing them small by a condenser lens 8 and a slit 7 having a circular opening part. Subsequently, an irregularly reflected light of two beams from the retina 1 is allowed to form an image by a photodiode 5 through a half mirror 3 and a photodetecting system objective lens 4, and converted to an electric signal by the photodiode 5. Next, by controlling the optical system, the reflected light A, B of two beams are set so as to be superposed on the photodiode 5. In such a state, when the person to be examined gazes at a target, focusing is executed by deformation of the crystal-line lens of the eye and an interval of two beams on the retina 1 is varied. Accordingly, by an output of the photodiode 5, the focusing reaction quantity of the eye can be detected.

Filed: 1979-08-28
Abstract: PURPOSE: To obtain high S/N, high defect output, good quality images and stable mechanical accuracy, in defect inspection of industrial products, by using a directional high cut space filter.  
     CONSTITUTION: A laser beam 2 is irradiated to the object 5 to be examined via a collimator 5, and the diffracted light 6 goes through a Fourier transform lens 7 and a space filter 8 to have the spectra corresponding to defect patterns transmitted therethrough and is then supplied via a reverse Fourier transform lens 10 to a photodetector 11, by which the detection of the defect parts is accomplished. Here, a directional high cut filter 20 is added to the filter 8. The filter 20 masks the θ direction where higher-order diffracted light regions are not recorded down to the lower-order diffracted light regions where spectra are recorded, opens to a high pass tendency and is formed into a shape corresponding to the directional component ratios of optical Fourier transform spectrum intensity distributions of roughly two- dimensional grating fringes. Thereby, the higher-order diffracted light centering at the θ direction is mostly cut.

Title: Gold plated electronic parts and production thereof
Inventor: NAGASHIMA TERUKICHI
IPC: C25D7/00
Filed: 1978-09-05
Abstract: PURPOSE:To produce captioned electronic parts of high quality even with thin gold- plated layer, by applying alloy-plating on the metal surface as the base coat for gold- plating, while adding replenishing solution containing specified Ni/Co ratio into alloy-plating solution containing Ni and Co. CONSTITUTION:When alloy-plating is applied to the metal surface by using alloy- plating solution containing Ni and Co, since Co deposits faster than Ni, a replenishing solution having a smaller Ni/Co ratio than the Ni/Co ratio in the plating solution is being added in the cource of alloy-plating. As a result, alloy-plating with stable quality may be obtained. It is preferable to keep the thickness of this alloy-plating layer within 0.1-10mu, and the Co content in the alloy within 2-60wt%. In this method, even if the thickness of gold-plating, which is usually 2-4mu, is made as thin as 1-2mu, the same performance may be obtained.

Abstract: PURPOSE:To make a type concn. uniform by a method wherein switching of a drive pulse amplitude is carried out against a continuously driven heat generating resistor as well as a drive pulse amplitude of the heat generating resistor adjacent to the heat generating resistor directly after the driving is also switched-over. CONSTITUTION:To regiters A, B, C, a dot-data to be typewritten, one preceding data and two preceding data are latched respectively. Now, when mono-multivibrators (A), (B) are triggered by dot timing, output of an OR-gate 10 comes to one level only for a time TC=TA+TB. Therefore, the dot data in a register (A) 1 is supplied to groups of an input gate 2 through groups of an AND-gate 7 only for a time TC. In this case, if output bit of a register (C) 12 corresponding to the input gate 2 is one and/or either one of output bits in both sides adjacent to output bit corresponding to a register (B) 4 is one, the output of a corresponded NOR-gate 11 comes to zero only for a time TA and the corresponding transistor 16 is driven only for a time TB.

Title: Laser welding method
Inventor: ISHIKAWA KEN
IPC: B23K26/20
Filed: 1978-09-06
Abstract: PURPOSE:To make sure welding and improve work efficiency in welding the lapped part of two metal plates of which at least one is coated with a material of lower boiling point than that of the base metal by detecting arrival of molten depth at the contact part of the two plates. CONSTITUTION:Metal plates 2, 3 coated with resin 2a, 3a etc. lower in boiling point than the base metal are placed on the stand 1 with the weld zone lapped. The laser beam L with energy density to melt and perforate the plates 2, 3 is output from the laser generator 4 by operating the control circuit 9. This is converged with the lens 5 and applied to the resin 3a to burn up the resin and then melt the plate 3. When the molten depth arrives at the contact part with the plate 2 and the resin evaporates rapidly in the molten pit by heat, the molten material in the pit scatters and hits against the pressue sensitive element 6. By this, the element 6 gives a signal to activate the timer circuit 8 and the laser generator 4 works for a specified time. When the welding is made satisfactorily, the circuit 8 gives a signal to the circuit 9 to stop the action of the generator.

Filed: 1981-07-15
Abstract: PURPOSE:To obtain a solidstate image pickup element which has sensitivity to infrared rays, by providing a signal charge storage area and a photoelectric conversion area where signal charges are generated by Schottky coupling. CONSTITUTION:Between an n type diffused layer 11 wherein signal charges are stored, and an n<+> layer 3 as an overflow drain, an overflow control gate part 12 made of an n<-> layer is provided. Further, a transfer control gate part 13 is provided so as to send stored signal charges to the n<-> layer 2 of a vertical transfer CCD. Then, a etching treatment is carried out in such a way that the entire surface of the n layer 11 is exposed as much as possible, constituting a Schottky barrier between, for example, Au and n<-> Si. Then, incident light energizes electrons in an Au electrode, and they enter the n layer side beyond the Schottky barrier to be stored as signal charges. Thus, sensitivity to light having higher energy than the threshold level of the barrier is obtained to convert infrared rays photoelectrically.

Title: Protective device for integrated circuit
Inventor: RI EIHOU
IPC: H01L29/78
Filed: 1995-05-08
Abstract: PURPOSE: To prevent damages caused by discharging of high-voltage static electricity by forming a protective circuit, with a P<+> -diffused resistor and an N-type well region diode and an N-type well region and a P-type substrate in series. CONSTITUTION: When an input signal is a positive high-electric potential, a diode D1 is energized for diode D2 to be reverse-biased for non-conduction. However, if the positive high voltage is higher than a reverse breakdown voltage of the diode D2, the diode D2 breaks down to form a discharge circuit, resulting in a large amount of current in the discharge circuit for protection. On the other hand, when the input signal is at a negative high-electric potential, the diode D2 is forward-biased for non-conduction. However, when a negative high- electric potential is higher than the reverse breakdown voltage of the diode D1, a discharge circuit is formed, for the flow of a large amount of current, thereby achieving protective operation. Hence, high voltage is prevented from being applied directly to the gate oxide film of an internal circuit.
