Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a broadcast system where a reception reproduction terminal can reproduce data of a high data rate periodically even under a communication infrastructure at a low transmission data rate. SOLUTION: A transmitter transmits program data Dp for real time reproduction and CM data Dcm1 for a post period while dividing a pre-period Tp equivalent to a total data rate of 6.4 kbps into a period equivalent to 4.8 kbps and a period equivalent to 1.6 kbps in each unit period TU. A reception reproduction terminal reproduces, e.g. program data Dp based on characters in real time for the pre-period Tp and stores C data Dcm1 for the post period into a data memory. The data stored in the data memory are read for the post period Tf and a moving picture or the like relating to data of a high data rate is reproduced on the basis of the data and CM command data Dcm2 transmitted at a total data rate of 6.4 kbps.

Abstract: PURPOSE:To provide an inexpensive sheet feeding mechanism by providing a feeding member moving against an energizing force in contact with a cam face when a carriage is moved out of a printing range, and transmitting means for transmitting the rotation of a sprocket wheel to be engaged with the member to a platen. CONSTITUTION:When a sheet feeding is not conducted, such as in a normal printing state, a carriage 15 is disposed in a printing range, a cam face 21a does not come into contact with a feeding member A, and the driving force of a space motor 20 is not transmitted to a platen 10. However, when the sheet is fed, such as in a line feeding, the motor 20 is driven to move the carriage 16 out of the printing range, the cam face 21a is contacted with the member A, the carriage 16 is further moved to move the member A, thereby rotating a sprocket wheel 29. The rotation of the wheel 29 is transmitted by transmitting means B to rotate the platen 10, thereby feeding a sheet 34.

IPC: G06T1/00
Filed: 1989-02-28
Abstract: PURPOSE:To stably detect a number plate area by calculating a density distributed quantity to a verification area set based on a relative position relation with a series of vehicle number candidate areas in a series of the vehicle number candidate areas, and verifying a series of the detected vehicle number candidate areas. CONSTITUTION:A candidate area verifying means 9 is provided which calculates the density distributed quantity in the verification area set based on the relative position relation with a series of the vehicle number candidate areas to a series of the vehicle number candidates detected by a candidate area detecting means 8, and verifies a series of the vehicle number candidate area detected by the candidate are detecting means 8 based on the value of the calculated density distributed quantity. Further for a series of the vehicle number candidate areas including a rough picture in a binary picture, a series of the vehicle number candidate area is verified by the density distributed quantity in the verification area set based on the relative position relation with a series of the vehicle number candidate areas. Thus even when the number of the digits of a series of the vehicle number is small, the number plate area can be stably detected from the binary picture including the rough picture.

Title: Manufacture of shadow mask
Inventor: KUSANO TOSHIZO
IPC: H01J9/14
Filed: 1988-02-29
Abstract: PURPOSE:To improve yield by welding the peripheral part of a mask and the side wall part of a frame with the bottom of the frame so supported as to prevent the lowering thereof. CONSTITUTION:When a frame 2 is placed on top of a contact pin 15 and a restriction pin 4 is engaged with the insertion hole of a support spring 3 for fitting the frame 2, the load thereof works on a slider 14 via the contact pin 15, thereby causing the downward motion of the slider 14. When an air cylinder 27 is operated at this position and a rod 28 is thereby pushed forward, a support block 22 advances along a rail 20 due to the effect of a compression coil spring 21, and the sloped surfaces 16 and 23 of the slider 14 and the support block 22 come in compression contact with each other via urethane rubber 24, thereby locking the downward shift of the slider 14. In this condition, a mask 1 is coupled to the upper side of the frame 2 and welding is applied thereto. According to the aforesaid construction, yield is improved without straining the frame 2 and the mask 1 during a welding process.

Title: Superconductive bistable device
Inventor: RUDORUFU JIYAGII
IPC: H01L39/14
Filed: 1980-04-14
Abstract: A switching and storage device is described in which a superconductor is arranged in regard to a magnetic or magnetizable element so that the magnetic field of the element surrounds the superconductor. The inner inductivity of the superconductor is subject to strong variation if at least one lateral dimension of the superconductor is comparable with or smaller than the penetration depth of the field into the superconducting material. If the superconductor is bifurcated, an electric current of sufficient magnitude fed externally distributes to flow essentially in one branch while the other branch essentially remains currentless. External control by a magnetic field can switch the current into the other branch, i.e., the device is bistable. The switching process inherently is fast and of low power consumption.

Title: Rolled wire rod superior in acid pickling property, and its manufacturing method
Inventor: SHIMOTSUSA MASAKI
IPC: C22C38/06
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a wire rod superior in acid pickling property by increasing a ratio of FeO being occupied in whole of the Fe base oxide at higher than a specific value in a scale at a wire rod transverse section. SOLUTION: It is preferable that a ratio of FeO being occupied in a Fe base oxide is set at 70% or higher in the scale at a rolled wire rod transverse section. In the scale, a Fe base oxide such as Fe3O4 and Fe2O3 or the like other than FeO are included. In this case, while FeO is comparatively soluble to an acid, many of the Fe base oxide other than FeO are unsoluble to the acid. Therefore, if ratio of the FeO included in the Fe base oxide is increased, acid pickling property is improved. Also, in order to control a scale composition like this, a temperature range of 600-400 deg.C during a cooling process of the hot rolling is required to be cooled at an average cooling rate of 0.5 deg.C/sec or more. Further, in order to obtain far superior acid pickling property, scale thickness at the wire rod transverse section is made to be 10 μm or less.
