Patent JP-H09321117-A (JP)
Title: Vacuum treating apparatus
Inventor: SORAOKA MINORU
IPC: H01L21/677
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To facilitate adding, changing and expanding of a vacuum treating chamber with reduced space by placing a first treating chamber at nearer position to an entrance/ejection chamber than a second treating chamber to suppress the lateral size increase in plan layout. SOLUTION: Two second large-outer diameter treating chambers 36A, 36C are parallel disposed at the far side of a load lock chamber 34 and longitudinally to a vacuum conveying chamber 37. Two first smaller-outer diameter treating chambers 36B, 36D are disposed approximately at both sides of the chamber 37 at the near side of the load lock chamber 34. This suppresses the lateral size increase in plan layout and length increase of a vacuum treating apparatus 300 away from the load lock chamber 34, thereby saving the entire space. This also minimizes the sample conveying length of a pneumatic conveying means, improves the throughput with adapting to large apertures of samples and suppresses the production cost rise.

IPC: B65H9/00
Filed: 1980-10-01
Abstract: PURPOSE: To easily receive a paper fed out from a copier by pressing the central portion of the paper with a pin outside a transport belt in the middle of transportation to turn it in a 90° arc by a carrying force of the belt, and releasing pressure of the pin to be transported again in the same direction by the belt.  
     CONSTITUTION: A paper A is transported in its longitudinal direction by a belt 8, and when the leading edge thereof is detected by a first detecting switch 21, a  switching transistor 23 is turned on to excite a solenoid 18. This causes a link 16 to  swivel anti-clockwise, so that a paper pressing pin 17 descends to press the central  portion of the paper A against a guide plate 1 and keep the paper A from advancing. On the other hand, since feeding force of the belt 8 and a feed roller 20 acts  upon the paper A, the paper A turns around the pin 17. A second detecting switch  22 is turned on when the paper A turns in a 90° arc and reaches a position A' to  demagnetize a solenoid 23 and raise the pin 17, so that the paper is transported in a  former direction again by a transport belt.

Title: High-sensitivity search signal detection radar system
Inventor: HIROZAWA HARUTAKA
IPC: G01S7/292
Filed: 1991-06-07
Abstract: PURPOSE:To improve the probability for capturing a reception signal by sweeping the reception band according to a saw-tooth wave of a frequency sweeping rate which is slightly different from the frequency sweeping rate of the reception signal. CONSTITUTION:A seep rate K2 of a saw-tool wave 21 and a chirp frequency sweeping rate K1 of an input signal IF are slightly shifted and matched, thus fully increasing a time width tdet: BW/(K1-K2) (BW is the bandwidth of BPF5) where the signal IF is detected. Since the BPF5 following the signal IF is a filter with a fixed center frequency, thus enabling the filter to be manufactured easily. Also, an equalizer 13 can be inserted owing to the fixed frequency, thus improving range side lobe which becomes a problem on pulse compression. An output signal Sv of a frequencyvariable voltage-controlled oscillator 10 can be frequency-converted as a local signal before and after the BPF5, thus enabling the inside of a broken line dtf to be equivalent to a dynamic tracking filter DTF of a basic radar system.
