Title: Modulation device
Inventor: IGAI KAZUNORI
IPC: H04L27/04
Filed: 1990-09-04
Abstract: PURPOSE:To map amplitude information to phase information, to give proof against phasing distortion and to reduce power consumption for transmission by adding a direct current component to the output of a filter generating a Hilbert transform pulse and setting an envelope fluctuation width to be a minimum. CONSTITUTION:An adder 14 adds the direct current component to the output of the filter 12. Thus, envelope amplitude becomes zero, envelope fluctuation is reduced and power for transmission is also reduced. Ternary amplitude information in the direction of a quadrature axis is mapped by phase information and amplitude information can be extracted from phase information even if a modulated wave is received by using a limitter amplifier in a receiver. Thus, proof effect against phasing distortion is given. A transmission band becomes equal to data transmission speed.

Abstract: PURPOSE:To attain excellent pickup without being affected by flair even in any of the color mode and the infrared-ray mode by removing an infrared-ray block filter. CONSTITUTION:In the case of picking up with the color mode by a conventional visual light, a turning position on an optical path of a filter disk 3 is selected to a position where a filter 4a, 4b or 4c having an infrared-ray block function is fitted.

Title: Automatic measuring method for moisture content of grain
Inventor: YAMAMOTO SOICHI
IPC: F26B25/22
Filed: 1986-10-03
Abstract: PURPOSE:To obtain an optimum number of measurements by calculating a moisture content measuring period in accordance with a difference between the initial moisture content and target moisture content of a grains, and measuring the moisture content of the grains at the calculated moisture content measuring period. CONSTITUTION:The initial (i=1) moisture content G1 of the grains is stored in a microcomputer and the measuring period T2 of the 2nd time is calculated from the difference (G1-Ga) from the target moisture content Ga by T2=K1(G1- Ga) (K1: constant). The moisture content measuring period of the 3rd time is obtd. by the rate of weight loss on drying (m) to be calculated by the difference between the moisture content G2 of the 2nd time and the initial moisture content G1 and the measuring time interval thereof. More specifically, the rate of weight loss on drying mi for determining the moisture content measuring period of the i-th time (i>=2) is determined by mi=[Gi-G(i-1)]/period. In other words, the drying time is shorter as the rate of weight loss on drying mi is larger, and the moisture content measuring period Ti is shorter as the rate of weight loss on drying mi is larger.

When no pullup is required, the gate level is kept to completely turn off the MOS TR Q11. Thus, the power consumption is reduced, the response is improved and the increase in the occupied area is prevented.
