Title: Reflective photosensor
Inventor: KASHIDA HAJIME
IPC: H01L31/12
Filed: 1986-01-31
Abstract: PURPOSE:To obtain a photosensor which is small in size, facilitates alignment at the time of mounting and, moreover, detects the direction of the rotation, the inclination and the direction of displacement of an object to be detected by a method wherein a photodetecting part is symmetrically divided into two parts and the output of each divided part is taken out independently. CONSTITUTION:A photodetector is composed of two phototransistors which are formed on a same chip 10 with a common collector 11. Photodetecting parts 12 and 12', e.g. base layers of the phototransistors, are formed into a same shape symmetrically. The respective characteristics of those phototransistors formed adjoiningly are almost identical with those phototransistors formed adjoiningly are almost identical with each other and variation between each other is very small, which is convenient to process the output signal. The respective outputs of the two phototransistors are almost identical with each other near a center line and, if the position of an object to be detected is shifted to any one of the directions, the output shows the operation as shown in the diagram. With this constitution, a direction of displacement and a direction of rotation can be detected and, if the object is inclined along the Y- direction, the amounts of light incident upon the two phototransistors are different from each other so that an inclination along the Y-direction can be also detected.

Title: Extraction of character data
Inventor: RICHIYAADO JIYOOJI KASEI
IPC: G06K9/34
Filed: 1990-02-01
Abstract: PURPOSE: To automatically extract data of characters which are written on a form by positioning a data mask, generated in a 1st array, in a 2nd array by using a calculated offset and extracting data corresponding to character pixels from the data mask in the 2nd array. CONSTITUTION: A master form description is generated from a blank master form and lines are recognized and discriminated by scanning paper for data to generate a data form description. The direction of the data mask to the master form is predetermined, so the data mask is converted into a data form image by using calculated values of a horizontal and a vertical offset and a gradient. External data are removed from the mask, which is expanded to acquire data; after lines are removed, data remaining on the mask are extracted and transferred to a new file. The data are processed by conventional OCR software to discriminate specific character values. Consequently, the character data entered into the form can automatically be extracted.

Title: Light emitting diode array
Inventor: MATSUSHITA TETSUYA
IPC: H01L33/12
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To avoid short circuit between electrodes disposed with a narrow gap therebetween by forming a recess between both electrodes having one and reverse conductivity types. SOLUTION: A recess 7 is provided between a first and second electrodes 5, 4 on a light emitting part. The recess 7 is formed from the same crystal as a reverse conductivity type semiconductor layer 3 simultaneously with the time when forming the light emitting part, and covered with a protective film at its surface. The planar distance between the electrodes 5, 4 can be held long, i.e., the distance obtained owing to the recess 7 may be represented by 2×(recess 7 depth) (1-cos θ)/sin θ (=an angle (<=90 deg.) between the slope and a flat part of the recess). Thus, it is possible to form a structure not raising the drive voltage VF value with avoiding short circuit between the electrodes 5, 4.

Title: Heat exchanger
Inventor: KIDO OSAO
IPC: F28F1/30
Filed: 1986-01-31
Abstract: PURPOSE:To provide a heat exchanger in which the heat transfer coefficient thereof between fins and an air stream is not lowered even in a heat exchanger long in the air stream direction and the heat exchange ability is large, by forming slitted and raised portions in parallel to the air stream direction into fin surfaces by bending a part of fins. CONSTITUTION:Heat exchange is carried out between an air stream B flowing through fins 5 and a heat medium flowing inside a flat pipe 1 via the fins 4 and the flat pipe 1. Upon this occasion, since the development of a temperature interface layer of the air stream B generated on the surface of fins 4 is interrupted by slitted and raised surfaces 5 and a long hole 6, and the slitted and raised surfaces 5 are formed vertically with the fins 4, the direction of development of the temperature interface layer generated on the slitted and raised surfaces becomes vertical with that of the temperature interface layer generated on the surface of fins 4. Therefore, the temperature interface layer is completely divided, and the temperature interface layer front edge effect of a maximum limit can be obtained. Further, since the slitted and raised surface 5 is formed in parallel to the direction of the air stream B, the reduction in the ventilation resistance can be realized.

Abstract: PROBLEM TO BE SOLVED: To obtain highly reliable three-dimensional-system acceleration sensor comprising a single element by performing the polarization processing, which can detect the acceleration components of X, Y and Z axes, in a ring-shaped piezoelectric element, and forming a corresponding divided acceleration- component detecting electrode. SOLUTION: When accleration is applied, inertial forces reverse to the acceleration act on component-detecting spindles 12a and 13a of respective axes for the two-dimensiona accelerations of the X and Y axes. Thus, shearing forces are applied to the X-axis and Y-axis component detecting parts constituted in a piezoelectric element 11. As a result, the potentials are generated at electrodes 12 and 13 of the X and Y axes. the magnitudes and the azimuths of the acceleration can be obtained by the vector synthesis of the potentials generated in the X axis and the Y axis. For the acceleration in the direction of the Z axis, the reverse inertial force acts on a metal base 10, which is supported by the central part, and the piezoelectric element 11 attached on the base 10 as the same way as in the two-dimensional component, and deflection stress is applied.  As a result, the potential is generated at an electrode 14.

IPC: H04N19/625
Filed: 1994-02-18
Abstract: PURPOSE:To reduce the frequency of FM writing at the time of encoding the moving picture by preparing the next RF in the present reference FM(RFM) area when the invalid blocks exist more than the valid blocks in one frame and preparing the next RF in the present encoding FM area when they exist less than the valid blocks. CONSTITUTION:Only a person at the center of the picture moves in a TV telephone and the other background part does not move so much. In short, when the moving part (the number of valid blocks) is fewer than the background part (invalid blocks), not the data of all picture blocks are stored in the encoding frame but only that of valid blocks are written when preparing the reference frame required to encode the next frame. When the number of invalid blocks is more than the number of valid blocks as the calculation result of counters 223 and 224 of an encoding control part 203, the next reference frame is prepared in the present reference FM area FM1 through an FM control circuit 202 by the instruction of a control part 23. When less, the next reference frame is prepared in the present encoding FM area FM2 and the frequency of writing in the memory is reduced.
