Title: Picture binary coding method
Inventor: EJIRI KOUICHI
IPC: H04N1/403
Filed: 1983-07-28
Abstract: PURPOSE:To perform optimum binary coding processing with good reproducibility by giving directivity to white picture elements contacting the contour of a picture which is coded into a binary signal with a rather small threshold value, and expanding the picture elements while comparing them with a picture which is coded into a binary signal with a rather large threshold value. CONSTITUTION:Picture information after MTF correction is coded into binary signals by using rather small and large fixed threshold values to obtain processed picture A(i,j) and B(i,j). The processed picture A(i,j) based upon the rather small threshold value is filtered to obtain a pattern C(i,j) given a direction code. Then, all picture elements are so treated that white picture elements are expanded in direction indicated by respective direction codes of the pattern C(i,j) over a comparison with the picture B(i,j), and the binary picture A(i,j) having no direction code is outputted as a processed picture D(i,j) without being processed.

Title: Method for illuminating electronic parts
Inventor: IZUMIDA KEIZO
IPC: G06T1/00
Filed: 1991-06-11
Abstract: PURPOSE:To enable generation of noise image to be minimized for reducing recognition error and achieve a more reliable position/attitude recognition by lighting a light-emitting body at a position which is determined by a function and then illuminating a needed portion by controlling an illumination angle, an illumination position. and a light-emitting intensity of an illumination light. CONSTITUTION:An illumination light-emitting control portion 2 receives shape characteristic data such as a type, a dimension, the number of electrodes, and a direction of electrode of electronic parts 10 to be illuminated, and then performs processing with a previously set function. An LED is turned on or off and a light-emitting intensity of the entire LED to be lit is determined by a function of the control portion 2. The illumination position control portion 4 receives a shape characteristic data of parts from the control portion 3, a distance between the LED and electronic parts and a lighting irradiation angle are determined for each side of four sides by a preset function, and then only a needed portion of the parts 10 is lit. A recognition error is reduced without achieving lighting with a brightness exceeding a required level and by minimizing generation of an unneeded noise image.

Abstract: PURPOSE:To inexpensively form a plane scanning mechanism with a simple structure by adopting an auto-focusing device using a layer-built piezoelectric actuator. CONSTITUTION:The reflecting surface of a rotary polygonal mirror 5 is arranged in the focus position of a parabolic mirror 6. A long-sized mirror 7 which refracts the luminous flux reflected on the polygonal mirror 5 and the parabolic mirror 6 is provided above a feed table 8. The first beam expander 2, an auto-focusing device 3, and the second beam expander 4 are successively arranged between a laser light source 1 and the polygonal mirror 5.

The luminous flux emitted from the polygonal mirror 5 is made incident on the parabolic mirror 6. At this time, the focal surface is not on a plane but forms a spherical face having a radius (q). With respect to the focal surface having the radius (q), the height from a plane is displaced by a length (h), which is expressed with a formula, in a position A which is a length X distant from the center. The displacement (h) of the focal surface from the plane is corrected by the device 3 using a layer-built piezoelectric actuator 11.

Title: Optical displacement detector
Inventor: TOSHIKAGE HIDEKI
IPC: G11B7/135
Filed: 1984-07-05
Abstract: PURPOSE:To perform accurate detection with a photodetector which is not so accurately positioned, by detecting the displacement of an object to be detected by detecting the intensity itself of diffracted and directly transmitted light from a hologram by means of the photodetector. CONSTITUTION:When the incident angle of light 2 on a hologram is changed, only the intensity is changed and outgoing angle from the hologram is not changed in respect of diffracted light. But, in the case of direct transmitted light, not only their intensity but also outgoing angle are changed. When the outgoing angle of the direct transmitted light from the hologram is changed and the radius rA of the spot on a diaphragm 7 becomes larger than the radius rB of an opening 7a, the direct transmitted light passes through the opening only in the ratio of rB<2>/rA<2>. Therefore, if the size of the opening 7a is previously selected so that all the diffracted light can be passed and the rB<2>/rA<2> ratio can change abruptly, quadratic-functional outputs are obtained from a photodetecting section 8a, but monotone-functional outputs can be obtained from another photodetecting section 8b, even when the diaphragm 7 is positioned between a recording medium and photodetector 8.

Title: Solar battery module
Inventor: IKEGAMI SEIJI
IPC: H01L31/04
Filed: 1980-10-06
Abstract: PURPOSE:To utilize solar energy extremely effectively in industry, by stabilizing the photoelectric conversion efficiency over a long period of time using a light weight solar battery module. CONSTITUTION:An overall electric output of a photovoltaic element part 12 is led to the outside by use of a lead wire or a lead plate 15', and an elongaged resin film 19 is contracted with heating, and further it is sticked fast to the rear surface of a substrate, i.e., the photovoltaic element 12 to constitute a protection layer, thereby the so called contraction packaging is performed. The contraction packaging is a light weight and inexpensive casing as compared with a convertional construction. And vinylidene chloride and polypropylene among the resin films do not affect the conversion efficiency of a CdS/CdTe solar battery module on a 10cm square glass substrate, for example, even when said module is subjected to a field test during one month (the decrement is practically zero.). Further, even for a CdS/Cu2S solar module, the decrement of the same conversion efficiency is close to nearly zero.

Title: Radio equipment
Inventor: KASHIMA KENICHI
IPC: H04B1/04
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To extend the operating t.ime of the radio equipment by controlling transmission power when an output voltage of a battery reaches a prescribed voltage to reduce the current consumption. SOLUTION: When a battery voltage of a power supply is reduced less than a prescribed set voltage, a voltage control section 10 is operated to set a reference voltage lower than a usual reference voltage. A comparator 9 provides an output voltage lower than the usual voltage to a transmission buffer amplifier 5, which is adjusted to reduce power sent from an antenna 1. When the battery voltage of the power supply is lower than a prescribed setting voltage, an output voltage is automatically decreased and the current consumption is reduced attended therewith through the control. As a result, the voltage drop is reduced and the operating available time per one charging is extended thereby extending the operating time of the radio equipment.
