Patent JP-H0253303-A (JP)
Title: Microwave oscillator
Inventor: MEGATA TSUYOSHI
IPC: H03B5/18
Filed: 1988-08-18
Abstract: PURPOSE:To attain miniaturization even when the oscillated frequency is low by providing an oscillator oscillating a signal with a frequency being a multiple of N of a required frequency and a 1/N frequency divider. CONSTITUTION:A termination open line 250 connects a drain terminal 220 of a FET 210 to ground equivalently in the vicinity of a frequency band twice the required frequency to cause a negative resistance to a gate terminal 230. Since the microstrip line 260 is coupled with a dielectric resonator 270, it acts like a band reflection circuit reflecting a signal with a frequency being twice the required frequency and the reflection is caused repetitively with a gate terminal 230 having the negative resistance and the oscillation is started at a frequency being twice the required frequency. The oscillated output signal from the microwave oscillation circuit 200 enters a 1/2 frequency divider 380 via the microstrip line 290 from a source terminal 240. The oscillated output signal with a frequency being twice the required frequency is frequency-divided by the 1/2 frequency divider 380, the result is a signal having the required frequency and extracted from an output terminal 390. Thus, the microwave oscillator is miniaturized.

Title: X-ray exposure method
Inventor: HONJO ICHIRO
IPC: G03F7/20
Filed: 1985-09-18
Abstract: PURPOSE:To enable the exposure of high resolution and high contrast with high throughput and its use for the formation of a minute pattern such as an IC by removing a component which has a value of the outgoing angle less than a definite one against the electron orbital plane of synchrotron radiation light. CONSTITUTION:When the kinetic energy of an electron of the light source 1 of synchrotron radiation (SOR) is, e.g., 600MeV, SOR light 2 of, e.g., less than 3mm (phi=0.3mrad) and more than 13mm is stopped by a slit 3 provided perpendicularly to an electron orbital plane at the position of, e.g., L=10m corresponding to each exposure condition vertically from the electron orbital plane. At the rear of the slit 3, exposure is carried out by simultaneously moving a mask 5 and an exposed substrate 6 vertically. In this way, the reduction of resolution due to the divergence of an photoelectron and the reduction of contrast due to the absorption factor of the mask and the wave length characteristics of resist sensitivity can be removed. Further, a short wave length component is harmful against the copying of a pattern and the temperature rise of an equipment, etc. so only the optimum wave length for SOR exposure is irradiated with sufficient power.

CONSTITUTION:A voice generated from a speaker A is inputted to a microphone 1A, and the voice and a delayed reverberation sound are detoured into a microphone 1B. In the same way, the voice generated from a speaker B also is detoured into the microphone 1A. For this reason, for example, an echo canceler 4B receives the output signal of an AD converter 3B generated from the speaker B, generates a pseudo detouring signal with the aid of an adaptive filter 40, and subtracts the pseudo detouring signal from the output signal of an A/D converter 3A with the aid of a subtracter 41. The voice signals of the speakers A and B, whose detouring signals are erased, are added by an adding circuit 5, converted into the analog signals by an D/A converter 6, and the voice high articulation can be outputted.

Abstract: PURPOSE:To simplify ex post facto dealing by judging whether or not paper sheets are received in a specified bin on the basis of the outputs of bin inlet and full-bin sensors to stop a conveyer means when the paper sheets are wrongly received in a bin other than the specified one. CONSTITUTION:This apparatus supplies the signal corresponding to bin No. CKBNO for detecting full-bin and empty bin conditions to a decorder 119 to drive a driver 118 and cause the corresponding full-bin detecting LED 43 to radiate. Next, it sends the output to the corresponding decorder 117 with a time delay and energizes a switch 116 to take out the output of the corresponding full-bin detecting photocell 41A and judge the wrong reception according to whether or not bin NO.s coincide with each other. When defective reception is judged, a control circuit 100 drives a driver 130 and turns off a clutch 131 in a vertical transfer section to stop the reception. Thus, the paper sheet which is about to be received in a wrong bin is placed at a bin inlet portion so that an operator can dicern between proper and wrong bins to simplify an ex post facto dealing.
