Title: Inter-frame coding/decoding system using leakage forecast
Inventor: OKUBO SAKAE
IPC: H04N19/65
Filed: 1992-11-19
Abstract: PURPOSE:To obtain an image of high quality without reducing the number of invalid blocks in a still area by setting up a valid/invalid block judging threshold to a large value in an inter-frame coding/decoding system using leakage prediction. CONSTITUTION:An image signal is supplied to a difference circuit 2 and an output from a leakage predicting circuit 11 is subtracted from the image signal. A valid/ invalid block judging circuit 3 calculates the average of inter-frame difference absolute values from the output of the circuit 2, judges validity/invalidity by comparing the calculated average with a prescribed threshold, and when the absolute value is valid, outputs the difference value to a coding/quantizing circuit 4. The circuit 4 executes prescribed coding and outputs a coded result to an entropy coding circuit 5 and an inverted quantizing/decoding circuit 8. The circuit 5 allocates a veriable length code and transmits the allocated result to the receiving side. On the receiving side, an entropy decoding part 52 decodes the data and supplies the decoded result to an inverted quantizing/decoding circuit 53. The output of the circuit is added to the output of a leakage predicting circuit 56, the added result is supplied to a display image preparing circuit 57, which sends an image not affected by a flicker or the like.

Title: Noise and vibration reducing device for planetary gear speed increasing and reducing gear
Inventor: ISHIKAWA JUN
IPC: F16H1/32
Filed: 1989-12-01
Abstract: PURPOSE:To prevent wide variation of appearance and to reduce the generation of noise and vibration through simple structure by forming a hole, with which a space is partially formed, in an internal tooth gear and filling the hole with a member formed of a material absorbing noise and vibration. CONSTITUTION:A partial hole 17 is formed in an internal tooth gear 8 and in a portion except an insertion hole 18 for a bolt 16. The hole 17 includes a hole formed in a grooveform state. Noise and vibration generated from a gearing part are damped in the space of the hole 17 and a level at which the noise and vibration is transmitted to the outside is reduced. By filling the hole 17 with a member 19 absorbing vibration and noise, a noise and vibration reducing effect is further improved. Not only a resilient substance, e.g. rubber, but also other metallic noise insulating vibration insulating member may be used as the material of the member 19. The internal tooth gear 8 forms internal and external multiplex structure, and by varying the respective materials, transmission of noise and vibration to the outside can be prevented.

Title: Taper-like optical transmission body and its production
Inventor: KONDO SABURO
IPC: G02B6/06
Filed: 1986-12-29
Abstract: PURPOSE:To obtain a high uniformity ratio by convergently arraying plastic optical fibers kept at a thick state, drawing out the convergently arrayed fiber flux under the fiber flux state, cooling and solidifying the drawn fiber flux, and cutting out a taper part. CONSTITUTION:Plural plastic optical fiber strands each of which consists of a core 13 and a clad 14 are inserted into a plastic pipe so as to make their long axis directions coincide with each other to form a rod, the rod is drawn out while being heated at a temperature higher than the thermal deformation temperatures of respective materials, and after cooling and solidifying the drawn rod, a taper part 10 is cut out. Since the strands are arrayed in the thick state, the array can be regularly, accurately and efficiently executed. Since the regular array is drawn out like a taper under the filling state in a plastic pipe and formed like thin fibers, the obtained fiber flux forms a taper-like transmission body having a similar shape while keeping the regular array as it is. Consequently, the taper-like optical transmission body reduced at its bleeding, having high resolution and free from image distortion can be obtained.

Title: Lens shape measuring device for spectacle frame
Inventor: ETO YASUTO
IPC: G01B21/20
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To smoothly mount and demount spectacles and to prevent erroneous deformation or the damage of a rim by a method wherein a pair of holding rods are provided to protrude from a holding surface and move integrally with a slider and support a rim from upper and below, and at least one of the holding rods is constituted in a manner to input and output from the holding surface. SOLUTION: Since the inclination guide plate part of a frame guide member is inclined in a direction in which an upper end is opened, when a spectacle frame is disposed between inclination guide plate parts and pressed down from above, a distance between moving frames 37 and 37 is increased, and a lens frame is moved to a position above holding claws 43 and 43 and locked at the holding claws 43 and 43. When, with this state, an operation lever 27 is rotated from an opening position to a closing position, the rotation is transmitted to a cylinder shaft 33 through a rotary shaft 25, gears 26 and 24, and an operation shaft 23.  By winding a part of a spring 35 around the cylinder shaft 33, a claw mounting plate 42 is rotated upward around one side part 42a through a wire 36 connected to the spring 35, a distance between the holding claws 43 and 44 is decreased, and the lens frame is held between the holding claws 43 and 44.

Title: Delay warrant type packet discard system and method
Inventor: HIRANO SATOYUKI
IPC: H04L47/20
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a delay warrant type packet discard system and method that can accept packets at maximum even with different requirements of packet length, fluctuation in transmission rate and delay in the packets. SOLUTION: A data management section 2 counts the number Di of transfer processing end packets at each measurement period, calculates an estimated number of resident available packets in a transmission buffer on the basis of the count, the measurement period and an upper limit of a transfer processing delay time, and transmits the result of calculation to a reception propriety discrimination section 3. The reception propriety discrimination section 3 compares a number of a constant or an estimated value outputted from the data management section 2 which is higher with number of resident i-packets in the node, discards arrived packets when the count is higher and accepts the arrived packets when the count is smaller and makes a request to a transfer processing execution section 1 for transfer processing.
