Title: Television lens system
Inventor: KAWAMURA HIROYUKI
IPC: H04N5/225
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the operability of a television camera by a cameraman by providing a balance weight member moved forward/backward in parallel with an image pickup optical axis of the television lens system and moving the balance weight member so as to cancel the movement of gravity center of the television lens system due to movement of at least a focus lens or a zoom lens thereby preventing movement of the gravity center. SOLUTION: A balance weight 40 is arranged in parallel with an image pickup optical axis 30 of a television lens system 12 in forward/backward directions freely. A motor 42 is arranged to move the balance weight 40. The motor 42 is driven by a CPU so that the balance weight 40 is moved to cancel movement position of the gravity center. For example, when a focus lens 32 is moved forward and the gravity center of the television lens system 12 moves forward, the balance weight 40 is moved backward to cancel the movement of the gravity center.

Title: Atmospheric power device
Inventor: YUASA IWAO
IPC: F03G7/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To catch the permanently infinite atmospheric pressure or outside pressure with a piston to take out and utilize the atmospheric pressure or the outside pressure by moving a piston installed on one end of a cup shaped vessel or a sealed vessel, generating negative pressure in the vessel, accumulating power, and delivering the power when the piston is returned by a difference between outside pressure and inside pressure. SOLUTION: When a lever 9 is moved, a brake belt 8 is released, a handle 6 fixed to a driving shaft 5 is turned, and a piston 1 is pulled, the piston 1 is moved outward while tightly fitting and sliding in the container 2, and negative pressure is generated inside. When the lever 9 is returned, a rotary barrel 7 is fastened by the brake belt 8, the operation of the fixed driving shaft 5 is stopped, stop is held. Pressure is rapidly reduced as an exponential function wherever a volume is increased since the relation between pressure and the volume in the container 2 is a constant relation. As a result, when the lever 9 is moved and the brake belt 8 is released, the piston is automatically moved and the driving shaft 5 is rotated, by a difference between outer pressure and inner pressure in the piston 1.

Filed: 1988-12-02
Abstract: PURPOSE:To prevent malfunction due to noise included in a PWM signal by providing a latch circuit and a reversible counter and applying latch and clear of each count in an input timing of a timing signal generated independently of the PWM signal. CONSTITUTION:Counters 21, 22 are cleared at a time tE1, make down-count due to production of underflow and convert into up-count at the leading of a pulse width modulation signal(PWM signal). When the PWM signal descends due to noise on the way of up-count, down-count is applied when the PWM signal is at a low level, an error due to noise is caused but no malfunction is caused. When a noise period is finished, up-count is restarted, the counters 21, 22 are subject to down-count at the trailing of the PWM signal and the count is latched in the timing of the trailing edge of the next RC pulse. The timing signal of the same period is generated independently of the PWM signal and the timing of the latch, clear or preset of the count content is controlled by the timing signal to prevent to production of malfunction due to noise included in the PWM signal.

Title: Shearing method of plate material and shearing device
Inventor: YAMADA HIROSHI
IPC: B23D19/04
Filed: 1993-12-03
Abstract: PURPOSE:To prevent deformation of a belt plate when a plate material is sheared into the belt plate by providing an energizing roller which energizes the plate material in the direction in which the original side of the plate material floats up from the top face of a shearing blade. CONSTITUTION:When a plate material W is fed between a pair of shearing blades A, B, the plate material W is energized by a roller in the direction in which an original side of the plate material W floats up from a top face of the shearing blade B so that the plate material W is not caught between the shearing blades A, B easily. Consequently, shearing is done without receiving unreasonable force, and deformation such as curling and cross bow does not occur in a belt plate W after shearing. Of course, if the plate material W is energized on an in side in the direction in which it floats up from the top face of the shearing blade B and it is energized on an out side in the direction in which it comes into contact with the top face of the shearing blade B, it is possible to reduce a possibility of being caught and prevent deformation further than in a case where either of them is done.

Abstract: PURPOSE:To attain signal exchange at high speed and broad band by providing a counter circuit, an exchange information storage circuit, a comparator circuit, a transmission information holding circuit and a shift register so as to constitute the titled switch without using any memory element. CONSTITUTION:The counter circuit 100 counts a pulse synchronously with an incoming channel of an incoming highway 2 and outputs an incoming channel number.

Title: System and method for processing image data
Inventor: JIENGUUNAN SHIAU
IPC: H04N1/403
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a process for removing a pattern shift artifact in a printed image by perturbing relation between a threshold and an image signal value. SOLUTION: The proposed process uses a programmable multilevel gray signal modifying circuit for modifying a multilevel gray signal only by a prescribed value in accordance with its gray level. The modified multilevel gray signal is binarized to a binary pixel signal in accordance with a relation between the modified multilevel gray signal and a threshold. The process generates an error corresponding to the relation and diffuses the error to adjacent pixels. The multilevel gray signal is modified by any random noise multiplied by a gray level dependent coefficient or a prescribed value from a checker board-like or vertical line-like pattern. The value from the pattern depends upon the pixel position of the image data or the gray level.

Title: Automatic vending device
Inventor: ASO FUKUO
IPC: G07F17/00
Filed: 1988-12-02
Abstract: PURPOSE:To reduce the number of times of feeding recorded media by detecting the stock value of the recorded media in which prescribed information is written in each information, and when the stock value of the media is less than the prescribed value, recording information indicating the drop of the stock less than the prescribed value in a prescribed recording medium. CONSTITUTION:When the regulated stock value of A cassettes 31 to B cassettes 34 are respectively regulated to 2 e.g., a stock value detecting means 41 transmits the reduction of the stock value down to one in any one of the cassettes 31 to 34 to a recording control means 42. The means 42 commands a master tape 40 to record music information to be recorded in the cassette reduced less than the regulated stock value. The master tape 40 is allowed to send the music information to a writing means 43 and the means 43 is allowed to record the music information in a raw cassette 21 sent from a storage case 20. Since the cassettes whose stock value is reduced can be formed in an automatic vending device 10, the number of times of feeding recorded cassette can be reduced.
