Title: Image transmission device
Inventor: MATSUI YOSHIHIKO
IPC: H04N19/423
Filed: 1988-05-30
Abstract: PURPOSE:To remarkably increase a transmission speed without spoiling the contents of an image by varying the transmission image data quantity in accordance with a frequency component of an image signal at the time of transmission. CONSTITUTION:An image signal which has been inputted to a transmitting part is converted to a digital signal by a sampling frequency 4fsc (14.32MHz), and stored in a video memory 3 through a switch 9. The image signal which has been stored in the video memory 3 detects a frequency component at every horizontal scanning line, and data is thinned out by a Nyquist frequency corresponding to a frequency band on its scanning line. Therefore, the transmission image data quantity can be compressed remarkably. In such a way, the transmission speed can be increased to several times of a conventional one.

Title: Camera system provided with camera-shake correcting function
Inventor: YAMAGUCHI MOTOYUKI
IPC: G03B7/16
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent a failure in picking up an image caused by a camera-shake and the blur of a main object, in the case that a camera-shake limit shutter speed becomes low to such a degree that the blur of the main object occurs. SOLUTION: In this camera system, a camera-shake amount is detected by using an angular velocity sensor, etc., for a camera-shake detector 252, the camera-shake limit shutter speed TVHh is calculated on the basis of the detected camera-shake amount and a main object blur limit shutter speed TVHs is calculated with the blurring amount of main object 2 detected by an image surface sensor 180, etc., to calculate an optimum stop value AVS and a shutter speed TVS by using either one of the camera-shake limit shutter speed TVHh or the main object blur limit shutter speed TVHs which is faster, as a blur limit shutter speed TVH. A diaphragm driving device 211 and a shutter unit 130 are driven by using those values. Further, a correcting lens driving device 251 is driven to correct the camera-shake.

Title: Piston for enclosed compressor
Inventor: SUGAWARA MAMORU
IPC: B21K1/18
Filed: 1980-09-19
Abstract: PURPOSE: To stabilize the function of piston and, at the same time, to prevent loss in volume due to deformation of the piston body, by thiciening the thickness of the wall at the top of piston than that of circumferential wall, when bottomed cylindrical pistons to be used for enclosed compressors are manufactured.  
     CONSTITUTION: A discoidal blank material 13 made of steel is put in a piston forming chamber 12 of a metallic mold 9 composed of die 11 set on the heat resisting plate 10, after the material 13 is treated by annealing and lubricating. Then, a pressure punch 14 b  is advanveced under pressure. When the punch 14 b  is advanced, plastic deformation is generated in the material 13, and the material 13 is expanded through the clearance between the pressure punch 14 b , and the piston forming chamber 12. When the pressing is completed, a cylindrical piston body 4 having a circumferential wall of t 2  thickness and a top wall of t 1  thickness which is 1.5W3times as large as t 2 , is formed in one body by cold forging. Since the thickness of the top wall is thick, the piston body 4 will not be deformed during the course of operation and a stable operation can be expected. Moreover, no loss in volume based on the increase of volume required for compression occurs.

Title: Collimator used for radiation surgical treatment
Inventor: MOSHIE EINNGARU
IPC: G21K1/02
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To to irradiate the boundary of a target by delineating and forming a radiation-impermeable and at least partially hollow radiation route. SOLUTION: An approximately radiation-impermeable beam shielding device 22 is arranged within an alignment device 20. The beam shielding device 22 is formable to an arbitrary shape, such as conical shape, and delineates the hollow beam expanded to the outer side by the hollow radiation route in a collimator 14. The beam shielding device 22 may also be constituted by disposing an external shielding body 30 having a hole 36 extending outward in a position 32 opposite to a large-sized irradiation source 34. An alignment device 40 forming the radiation beam route converging in a non-hole is preferably arranged in the hole 36. The beam shielding device 42 is arranged therein. The beam converges near the outlet of the collimator 14 and turns hollow. The beam turns non-hollow as the beam parts from the collimator outlet.  The beam spreads to the distance apart from the focus, thereby turning hollow. As a result, the radiation dose in the central part of the contour is made as low as negligible.

Title: Track address pattern for magnetic disk device
Inventor: SUGITA JUNKICHI
IPC: G11B5/596
Filed: 1990-05-21
Abstract: PURPOSE:To record a track address at a high code rate by grouping the gray codes of plural bits corresponding to the track address for every two bits, converting the code to the code of three bits corresponding to the value of the group and recording the code to a magnetic disk. CONSTITUTION:First of all, the binary numbers of 12-bit is converted to gray codes A11, A10,...,A1, and A0 (source codes) of 12-bit. Afterwards, the gray codes of 12-bit are divided for every two bits, and the respective codes of two bits are converted to the channel data of three bits by 2/3 conversion. Therefore, encoder addresses B17, B16,...,B1 and B0 of 18-bits are generated as a whole and recorded to the area corresponding to an address pattern 5 in the magnetic disk. Thus, the code rate as a ratio between the number of bits in the source data and the number of bits in the channel data becomes 2:2, namely, becomes 0.67 and the code rate is improved.

Filed: 1987-05-27
Abstract: PURPOSE:To improve the speed and accuracy of plate inspection by forming charts for registration to the four sides of each of two plates, forming many parallel lines vertically and horizontally to the charts and matching the centers thereof. CONSTITUTION:The plate inspection is executed prior to printing by disposing the two plates 10, 11 on a table, photographing the respective plates 10, 11 and displaying the images thereof in superposition on a monitor television. The charts 14 to be used for registering the relative positions of the plates 10, 11 to a camera such as television camera to be used at this time have the many vertical and horizontal parallel lines, allow the matching of the centers thereof and are formed on the four sides of the respective plates. These charts are, therefore usable at the time of subjecting the in-process products to which pin holes cannot be formed to the plate inspection or at the time of inspecting the two plates such as, for example, positive film and blue print, which vary slightly in size by elongation and contraction. The mis-registration in X-Y directions and twist direction is thereby detected and is corrected with good accuracy.
