Title: Reassembling system using ip router router
Inventor: SEKINE AKIHIRO
IPC: H04L12/70
Filed: 1993-10-28
Abstract: PURPOSE:To reduce the load on a network by enabling an IP router to reassemble a datagram based on the maximum transfer unit when the datagram passe through the networks of different maximum transfer units. CONSTITUTION:The maximum transfer unit MTU set between IP routers 28 and 29 is set at 8KB which is different from a datagram 26 of 7KB when the datagram 26 is sent to a TCP 25 of a destination host Host 2' from a TCP 24 of a source host Host 1'. Under such conditions, the router 28 sends the datagram 26 to an IP 29 as the final datagram 33 of 7KB and without fragmenting the datagram 26. If the MTU is set at 3KB between IP routers 29 and 30, the datagram 26 is fragmented and reassembled and then sent to a router 30. In the same way, the datagram is reassembled by each router so that the number of datagram passing through the networks of different MTUs can be minimized and the network load can be reduced.

IPC: G05B19/4097
Filed: 1985-11-30
Abstract: PURPOSE:To shorten the NC data generation time by inputting coordinate values of one block through a tablet and other additional data through a menu table, etc. CONSTITUTION:An NC data generator is constructed of a processor 11a, a ROM 11b, a RAM 11c, a display device 12, the tablet 13, a keyboard 14, a disk controller 15 and a floppy 16. The tablet 13 is so constituted that the menu table 13c on which data items except for coordinate values are entered is placed on a tablet face 13a and data other than coordinate values can be inputted by instructing the prescribed data item on the table 13c. Thus positions on a drawing are inputted through a mouth 13d, and such discrimination is made whether additional data except for the position coordinate values is necessary or not. If so, the prescribed item on the menu table 13c is instructed, and data on the item is inputted. Accordingly NC data is generated from both inputs, and that procedure is repeated by one block, thereby generating aggregated NC data.

Abstract: PURPOSE:To increase the sharpness of a video by applying the horizontal scanning speed modulation of an optimum electron beam to two videos or more different in horizontal deflecting frequency, respectively. CONSTITUTION:The horizontal synchronizing signal of a video signal is inputted to a terminal 11, and a frequency discriminating circuit 12 integrates horizontal synchronizing signal SH inputted in 1 vertical synchronizing period and outputs control signals (b) and (c) based on the voltage signal equivalent to the number of input signals For a variable voltage power source 13, an output voltage is changed over by the control signal (c). For a differentiation circuit 2, a peaking frequency is changed over by the control signal (b).

Abstract: PURPOSE:To improve the control precision of a clock signal used as the horizontal synchronizing signal of an inputted MUSE signal, and to reduce jitter components. CONSTITUTION:The horizontal synchronizing signal in a high definition television signal band-compressed and A/D converted in an MUSE system is compared with the frequency-divided result of the clock signal generated from a voltage control oscillator 13 by a phase comparator circuit 9.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To form no carbonized layer in a cut surface by irradiating the CO2 laser beam for cutting the FRP of a work while oxygen is blown as the assist gas. SOLUTION: The CO2 laser beam L to be oscillated from a CO2 laser beam oscillator 1 is converged by a converging lens 3 in a focus head 2. An FRP 4 which is a work is irradiated with the laser beam L and the FRP 4 is cut thereby. Oxygen 5 is blown from an assist gas passage 6 provided on the focus head 2. Oxygen 5 completely burns the FRP 4 on the cut surface to prevent a carbonized layer from being formed on the cutting surface. The secondary machining to remove the carbonized layer is dispensed with. To obtain the excellent carbonization preventive effect, it is necessary to provide oxygen 5 of >=3kg/cm<2> in gas pressure. Formation of the carbonized layer can be prevented without using an expensive excimer laser beam oscillator.

Title: Slag cut ball
Inventor: TACHIKAWA AKIHIRO
IPC: F27D3/14
Filed: 1993-10-29
Abstract: PURPOSE:To improve a slag cut effect by prevention of failure at the time of use and an increase in bulk sp. gr. by limiting the content of the alumina cement of castable refractories for covering the outside surfaces of arbors. CONSTITUTION:The balls are constituted by limiting the content ratio of the alumina cement in the sheath refractories to 1 to 9wt.%. As a result, the water of crystallization contained in the refractories is made less than in the conventional refractories and the bulk sp. gr. of the balls is increased. Then, the balls are held in a sunk state without generating the crack and destruction by a rapid temp. change when the balls are charged into the furnace and, therefore, a slag cut rate is improved. The degradation in the hardening strength by a reduction in the content ratio of the alumina cement is sufficiently dealt with addition of 0.1 to 5wt.% superfine powder of silica and 0.01 to 1wt.% dispersant, such as phosphate, carboxylate or silicate of alkaline metals to the refractories.

Abstract: PROBLEM TO BE SOLVED: To facilitate the angular adjustment of an objective lens, while a positional relation is ideally maintained between an adjustment coil and a yoke part, by making rotatable a movable part holding the objective lens and the adjustment coil together with the yoke part. SOLUTION: A movable part holding an objective lens 16 and an adjustment coil 18, 19 are elastically retained with a damper holder 25, and also unified with a yoke 30 by screwing.
