Title: Transmission
Inventor: HASHIMOTO SUMIO
IPC: F16H3/10
Filed: 1986-06-28
Abstract: PURPOSE:To enable transmission of an output during reversing, by a method wherein a solar gear with a one-way clutch and an integral rotary arm are mounted on an input shaft, an arm with a one-way clutch and a transmission gear are mounted on the support shaft of a planetary gear and the support shaft of an arm with a one-way clutch, and a driven gear geared with the transmission gear is mounted on an input shaft. CONSTITUTION:When a motor 1 reversed, an arm 10 is also integrally rotated along with rotation in a direction B of an input shaft 2. Since a solar gear 6 is not rotated by means of a clutch 9, a support shaft 12 and a transmission gear 16 are revolved along with revolution in a direction B of an arm 10. Since the support shaft 12 is rotated in reverse direction to a direction C based on the arm 10 but the solar gear 6 is not rotated, the planetary gear 14 is rotated in a direction D as it is revolved in a direction B. The transmission gear 16 is rotated as it is revolved, and a driven gear 17 geared with the gear 16 is rotated in a direction B. since the diameter of the transmission gear 16 is differed from that of the planetary gear 14, the gear 16 moves the gear 17 to a point (d). Since a rotation speed ratio of an input shaft to an output shaft is set to 1/10, the speed of the output shaft is reduced to 1/10 of that of the input shaft.

Abstract: PURPOSE:To make the power consumption of the whole element constant by stacking a Peltier element and a heating resistance body on a substrate and constituting a thin film cooling element, and computing the power consumption of the Peltier element which varies with humidity and controlling electric power supplied to the heating resistance body. CONSTITUTION:The Peltier element 2 and heating resistance body 50 are stacked on the substrate and the heating resistance body 50 is so controlled that the sum of the power consumption of the Peltier element 2 and the power consumption of the heat resistance body 50 is always constant.

Further, when a thermocouple is used to detect the water drop temperature of the cooling part for the Peltier element 2 and obtain an output corresponding to the temperature difference between the substrate temperature and water drop temperature, the water drop temperature is accurately obtained from the room temperature. Further, when a resistance bulb is stacked on the substrate, the temperature rise value to the room temperature of the substrate is constant, so the room temperature is accurately found to obtain the absolute humidity from the water drop temperature and the relative humidity from the water drop temperature and room temperature.

Abstract: PURPOSE: To attain a high speed reading operation following a writing operation by starting pre-charging with a pulse produced from a write enable signal before pre-charging with a pulse produced from an address fluctuation detector. CONSTITUTION: When a writing operation is changed to a reading operation, N channel MOS transistors 16 and 17 are turned ON by a pulse ϕWE produced by a write enable signal and a bit line BL and the inverse BL are charged to specified levels. Then, the bit line BL and the inverse BL are completely pre-charged in transistors 11 to 13 which respond to a pulse inversion EQ produced from an address fluctuation detector (ATD). Transistors 14 and 15 are always turned ON by high resistance and a current for compensating for the leaked amount from the bit line during a long cycle is supplied. Thus, by performing pre-charging in two stages, a high speed for a reading operation following a writing operation is attained.
