Patent JP-S5848538-A (JP)
Title: Pll oscillator
Inventor: KAWADA KAZUHIDE
IPC: H03L7/183
Filed: 1981-09-18
Abstract: PURPOSE:To lock a PLL to a frequency dividing ratio N to be set in a short time, by comparing the N with a reference frequency dividing ratio Nr, setting the Nr as a dummy to a variable frequency divider at N>=Nr, and setting the N to the variable frequency divider after the Nr is tentatively locked to the PLL. CONSTITUTION:A content N of a frequency dividing ratio storage device 11 and a content Nr of a reference frequency dividing ratio storage device 12 are compared at a comparator 14 and the result is inputted to one terminal of an AND gate 15. At N=Nr, the comparator 14 outputs a high level to the AND gate 15. In this case, a monostable multivibrator 16 is triggered with a set signal input 18, a high level is applied to another input of the AND gate 15, a selection signal of a selector 13 goes to a high level and the Nr is selected as a data of a variable frequency divider 19. After a prescribed time is elapsed, an output of the monostable multivibrator 16 goes to a low level and the selector 13 selects the N to the frequency divider 19. Thus, since the frequency of a PLL is locked to the N via the Nr, locking can be done in a short time without getting out of the lockable range.

Title: Solar beam direction sensor
Inventor: NAKAMURA TAKAHIRO
IPC: G01C1/00
Filed: 1993-05-14
Abstract: PURPOSE:To allow detection of the incident direction of solar beam over a wide range using an inexpensive and convenient constitution by interposing a shade wall between sensors and then comparing the outputs from both sensors. CONSTITUTION:When a shade wall 1 is interposed between optical sensors 2, 3, the shade wall 1 casts a shadow on the sensor 2 for a solar beam entering 4 in the direction closer to the sensor 3 than a plane in parallel with the shade wall 1 and thereby the sensor 2 produces an output lower than that from the sensor 3. On the contrary, when the solar beam enters 4 in the direction closer to the sensor 2, the sensor 3 produces an output lower than that from the sensor 2 and when the solar beam impinges on a plane in parallel with the shade wall 1, the sensors do not cast any shadow and produce substantially equal outputs. Consequently, the incident direction 4 of solar beam can be detected by comparing the outputs from the sensors 2, 3. This constitution realizes an inexpensive and convenient sensor having a wide range of incident direction.

Title: Method and device for transporting gas selectively
Inventor: TAMAOKI MASAYOSHI
IPC: F28D15/02
Filed: 1985-07-05
Abstract: PURPOSE:To transport gas selectively by a method wherein the gas, sucked selectively into a heat pipe by a selective permeating device for separating gas (membrane) in a heating area, is transported, diffused and pressurized by the stream of vapor of heat-pipe operating liquid while the gas is separated selectively again by the membrane in a cooling area. CONSTITUTION:Primary series gas in an introducing section permeates selectively through the membrane A and is sucked into the heat pipe. The stream of vapor, generated in the heating area, arrests the gas and moves to the cooling area while forming the mixed stream of both of gas and vapor. The vapor in the cooling area is condensed and liquefied, then, is circulated into the heating area by the capillarity or gravity possessed by the wick, only the gas is blown to the cooling area by the stream of vapor and is pressurized through a vapor- gas diffusing area while the primary series gas is changed to secondary series gas and is stagnated. The secondary series gas permeates selectively through the membrane C again and is discharged as tertiary series gas.Through these processes, the selective transporting effect of gas, in which the gas in the primary series is transporting effect of gas, in which the gas in the primary series is transported selectively to the tertiary series, is operated.
