Title: Scanner for facsimile
Inventor: AZAMI SHINTAROU
IPC: H04N1/387
Filed: 1981-03-25
Abstract: PURPOSE:To grasp the correlation between a transmitted picture or writing and a scanning range easily by making the operator observe the correlation between the outside frame of the scanning range of a scanning surface and the position of the focused image of the transmitted picture or writing through an optical instrument or a television monitor. CONSTITUTION:The surface of a picture to be transmitted is irradiated by an illumination lamp 2 and its image is formed on a scanning surface 4 through a lens 3. A photoelectric conversion element 5 converts the image of the transmitted picture into an electric signal while moving within a scanning range. Although the scanning range has already been fixed, the position of the formed  image is variable. When a mirror 6 is located in the position 6' in a light passage, light from the surface of the picture to be transmitted is reflected by the  mirror 6' and its image is formed on a supervisory window through a mirror 7  and lens 8. Thus, the operation can confirm the relative positions of the manuscript 1 and the scanning range by observing the monitoring window 9.

Title: Communication synchronizing method, tdma communication equipment, and tdma communication system
Inventor: NISHIKAWA MASAYUKI
IPC: H04B7/212
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To make a closed loop type transmission synchronizing method applicable even to a 1:m wired TDMA(time division multiple access) communication system. SOLUTION: In establishing communication synchronization, a subordinate station 22-2n to be synchronized sends a deviation measuring signal at the timing based on a prescribed point of signals received from a base station 21. The station 21 echoes back received signals in an acquisition window set by the station 21 itself without recognizing the receiving timing of the deviation measuring signal. The subordinate station 22-2n to be synchronized adjusts the sending timing of the next deviation measuring signal based on the presence/ absence or existing position of the deviation measuring signal in the echoed-back signals. The communication synchronization is established by repeating the above signal delivery and reception.

Abstract: PURPOSE:To make it possible to form a semiconductor device having the equivalent characteristics as those of a semiconductor device using single crystal silicon on an insulating substrate without dispersion, by forming a crystal region of a polycrystalline silicon at a specified position on the insulating substrate, and forming the semiconductor device such as a thin film transistor in the crystal region. CONSTITUTION:A silicon thin film 1-2 is deposited on a transparent insulating substrate 1-1. An island shaped metal thin film 1-3 is formed on the silicon thin film 1-2. A plasma oxide film 1-4 is grown on the surface of the silicon thin film that is not covered with the island shaped metal thin film 1-3. Then, the island shaped metal thin film 1-3 is etched away. Island shaped window is provided in the plasma oxide film 1-4. Island shaped silicon surfaces 1-5 are exposed. Then, an amorphous silicon thin film 1-6 is deposited, and crystal is grown. The crystal growing starts at the contact planes between the island shaped silicon surfaces 1-5 and the amorphous silicon thin film 1-6. The crystal grains collide one another at the intermediate point between the island shaped silicon surfaces. Thus a grain boundary 1-7 is formed. When the distance l between the island shaped silicon surfaces 1-5 is made to be 100mum or less, a region between the island shaped silicon surface 1-5 and the crystal boundary 1-7 becomes a complete crystal region 1-8.

Title: Method for extracting object
Inventor: TAKAHASHI HIROKO
IPC: G06T9/20
Filed: 1989-02-27
Abstract: PURPOSE:To stably extract an object even when a shadow exists by sorting areas based upon the multiplication of a constant by an intensity ratio to be the physical information of an edge from already recorded image information. CONSTITUTION:A characteristic value determining part 1-2 determines the characteristic value of an image recording system by using relation between intensity obtained by formulating an image recording system used by an image input part 1-1 and a density value and the density of an image obtained by the image input part 1-1. An intensity ratio evaluating processing part 1-3 finds out the intensity ratio evaluating value of each edge of an image by using the characteristic value of the image obtained by the processing part 1-2 and sorts the edges in each intensity ratio evaluation from the obtained evaluation value and the distribution. An object detecting/segmenting part 1-4 segments only the edge having the fixed intensity ratio evaluation value based upon the sorting of the intensity ratio evaluation values of the edges obtained by the processing part 1-3. Consequently, even when the shadows of the object are overlapped to each other, the object can be stably extracted from the density information of the image.

Title: Vehicular product with protector
Inventor: SAKATA KOICHI
IPC: F16J15/10
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To facilitate provisional fixing work, to reduce a number of parts to be fixed provisionally, and to reduce an amount of adhesive. SOLUTION: An adhering recess 160 of a finisher body 1 is brought into close contact with an adhering leg 210 so that the finisher body 1 and the protector 2 are provisionally secured to each other. Accordingly, provisional fixing operation is facilitated as compared with a prior operation which uses a double- faced adhering tape. The adhering recess 160 and the adhering leg 210 are thus closely fixed temporarily so that an adhesive 30 may spread out therebetween by capillarity. No double-faced tape is needed, therefore, and a number of parts to be fixed provisionally is reduced. The adhesive 30 spreads out between the adhering recess 160 and the adhering leg 210 by capillary action to secure the finisher body 1 and the protector 2, resulting in a reduction in amount of the required adhesive.
