Abstract: PURPOSE:To shorten the time required for repicking-up of a satellite by means of a mobile station in a moving-body satellite communication. CONSTITUTION:When radio waves from a satellite cannot be received due to the shadow of a building or the like, an antenna control device 3 for an antenna 1 for satellite communication use which is mounted on a moving body such as a vehicle or the like and which is provided with the tracking function of the satellite detects the azimuth of the moving body by means an angular- velocity sensor 4, directs the antenna 1 to the direction of the satellite and, at the same time, detects the velocity of the moving body by means of a velocity sensor 5. Then, the maximum continuation time, of a tracking operation, which has been detected by means of the angular-velocity sensor 4 is controlled by means of the velocity of the moving body. When the velocity of the moving body is comparatively slow, the maximum continuation time is made long. When a state that the radio waves cannot be received is continued for many hours even at a short distance such as a stop due to a traffic signal or the like, a tracking operation by means of the angular-velocity sensor 4 is continued.

Filed: 1983-03-08
Abstract: PURPOSE:To absorb irregularities in characteristic of a heatsensitive oscillator by making the oscillation frequency of the heatsensitive oscillator coincide with a reference signal frequency for measurement at a specified temperature with a frequency conversion circuit using a rate multiplier. CONSTITUTION:Output from a crystal oscillator 1 via a division circuit 2 with a rate multiplier 2c of a frequency conversion circuit 12 in a temperature compensation circuit 6' is processed according to a set value of a rate memory 12a. Then, an output frequency signal of a heatsensitive oscillator 7 from the multiplier 12c is counted so that the output of the oscillator 7 will coincide with the reference signal for determining temperature information at a specified temperature corresponding to the crest of a temperature-frequency curve of the oscillator 1. Thus, irregularities in characteristic of the oscillator 7 are absorbed in substance to reduce the number of external adjustors thereby enabling the compensation for the temperature of an electronic timepiece at a high accuracy with a small construction.

Abstract: PURPOSE: To easily hang a skirt or the like on a hanger even as a jacket is hung thereon by cutting about the center of the trousers hanging arm of the hanger for hanging clothes to provide a clearance. CONSTITUTION: About the center of the arm 1 of a trousers hanger is cut to provide a clearance 2, and a pair of trousers or a skirt is hung through it. When the trousers are hung over a long period, the hung trousers can be prevented from being wrinkled if the clearance 2 can be closed. Thus, a laterally slidable cylindrical cover may be mounted on the clearance part 2 so that it can be moved after the trousers are hung to close the clearance 2. After a jacket is hung on the hanger, the trousers or skirt can be easily hung without removing the jacket. In case of the skirt, particularly, the skirt can be easily hung by use of a hanging cord 3, and is also hard to wrinkle.

Title: Halftone dot generating device
Inventor: MATSUSHITA HIROYUKI
IPC: G06T5/00
Filed: 1989-02-16
Abstract: PURPOSE:To optionally change the angles of halftone dots and to prevent the moire produced in printing by using a 2-dimensional threshold value store ROM and a single row threshold store RAM to successively shift the threshold data blocks and converting the halftone picture data on the input into the binary picture data. CONSTITUTION:A 1st means 12 produces the address signals corresponding to the main and secondary scan positions, and a 2nd means reads out the threshold value data stored previously in a 2-dimensional threshold value store ROM 14. A 3rd means stores the threshold value data obtained from a 2nd line into a single row threshold value store RAM 13. Then a 4th means 15 converts the halftone picture data on the input into the binary picture data via the outputs selected out of the 2nd and 3rd means. Thus the angles of halftone dots can be changed via a signal process for the threshold data which converts the halftone picture data into the binary picture data on the halftone dots. Then the moire produced in printing can be avoided.

Filed: 1990-02-20
Abstract: PURPOSE: To improve system performance by providing a means execution data consistency procedure to the data based on the comparing result and state information of a comparing means to reduce the traffic of a shared path. CONSTITUTION: A reference value register 6 stores a reference value in connection with the access count of a cache tag and a comparator 7 compares the access count of a cache tag specified by address information with the reference value of the reference value register 6 to supply the comparing result for a cache control part 3. In this case, with respect to data to which only one processor P frequently access, even though originally shared data, its copy is made to remain only in the cache C of the frequently accessing processor P and its copy within the other caches are invalidated. As the result of the, there is no copy in the other caches C after invalidating so that processing can be executed only within one's own cache C, thereby improving the performance of the bus of the cache to maximum.
