Title: Transmission/reception equipment
Inventor: YAMAURA TOMOYA
IPC: H04J13/00
Filed: 1991-09-13
Abstract: PURPOSE:To always make a proper value of the transmission power of a mobile station even at the time of first transmission. CONSTITUTION:The spectrum spread signal (a synthesized signal of respective channels) from a down converter 7 is supplied to a level detecting circuit 12 through a distributor 11 to detect the reception signal level. A control circuit 13 compares the reception signal level with the transmission power of a base station to estimate the loss due to a transmission line. The gain of an output amplifier 5 is adjusted by the control circuit 13 to control the transmission power so that the reception signal level is proper in the base station. This control of the transmission power is repeatedly executed. Since the transmission power is always controlled to the proper value, the mobile station communicates with the proper transmission power from the first transmission. Thus, the base station receives a signal with the proper signal level from the first and surely communicates. Since the mobile station always transmits a signal with the proper power, the power consumption is reduced, and a mounted battery is miniaturized and its life is extended.

Filed: 1988-09-21
Abstract: PURPOSE:To provide both heat shock resistance and adhesiveness to a surface to be coated of a zircon-containing refractory by causing the title material to comprise zircon in an amount in a specified weight percent range and chromite in an amount in a specified weight percent range. CONSTITUTION:The title material comprises 20 to 90wt.% of zircon and 10 to 80wt.% of chromite.

Title: Conversion of character font
Inventor: NOGUCHI YOSHIHIRO
IPC: G09G3/32
Filed: 1987-09-21
Abstract: PURPOSE: To automatically convert a regulated character font into a character font to be used for a road information display device by dividing an enlarged character font into J×K segments and determining the binary function value of each segment based upon a prescribed threshold. CONSTITUTION: When the number of ON dots out of dots in a prepared block exceeds a fixed rate, the block is turned on, and when the number of ON dots is less than the fixed rate, the block is turned off, so that the number of blocks becomes J×K blocks. Thereby when dots are substituted for a block, the block can be converted into a character font consisting of J×K dots. Since the conversion is not influenced by the size relation between J and M and between K and N and can be also executed even when a J/M rate and a K/N rate are respectively optional values, a new character font can be prepared by converting a regulated character font into a clot matrix having different number of segments.
