Title: Elastic surface wave resonator
Inventor: YAMAMOTO TAIJI
IPC: H03H9/25
Filed: 1982-12-23
Abstract: PURPOSE:To obtain an elastic surface wave resonator with small size and low cost without adhering especially an absorbing band by forming a drawing-out electrode pad of an interdigitating electrode to both ends in the propagating direction of an elastic surface wave on a piezoelectric substrate. CONSTITUTION:Each electrode finger of the interdigitating electrode 12 is connected alternately to conductors 21, 22 and the leads 21, 22 pass respectively through both sides of the elastic surface wave propagating path and are connected to the drawing-out electrode pads 25, 26 formed at both ends of the elastic surface wave propagating path on the piezoelectric substrate 11. Electrodes 13, 14 are grating electrodes arranged at an equal interval on the elastic surface wave propagating path. Thus, it is not necessary to widen the width of the piezoelectric substrate 11 to form the electrode pads 25, 26, and since an unnecessary elastic surface wave is absorbed by the electrode pads 25, 26 and lead wires connected thereto, no special absorbing band is required. Thus, miniaturization and low cost are realized.

Abstract: PURPOSE:To continuously perform multistage gaseous phase reactions in a series of systems, by constituting a reaction apparatus by arranging a plurality of reaction chambers having respectively different energy applying means along the flow passage on the downstream side of a nozzle injecting a raw material. CONSTITUTION:When the ratio of the pressure in a raw material chamber 7 and that in a reaction chamber 2a is set to a critical pressure ratio or less, the outlet flow velocity of a contracting and expanding nozzle 1 becomes supersonic velocity and raw material can be injected at supersonic velocity. When the raw material is injected in a definite direction as the proper expanded stream of supersonic velocity mentioned above, the raw material straightly advances while holds the jet stream cross-section immediately after injection to be formed into a beam stream. By this method, the raw material is injected in reaction chambers 2a, 2b and a collection chamber 6 while diffusion is suppressed to the min. in a spatially independent state generating no interference with the wall surfaces of said chambers.

Filed: 1983-11-30
Abstract: PURPOSE:To obtain a synchronizing dynamic counter by providing a function which is capable of the increment, decrement and reset by means of the increment signal and the decrement signal of external input in addition to the counter reset signal. CONSTITUTION:An external input clock INC is applied in an increment mode while a clock DEC (not shown in the diamgram) is kept at a high level. A clock BORROWi is kept at a low level. A counter receives the control by clocks UCP, UCE, CP, CE and CARRYi produced by an external clock INC. Therefore transistors Q50 and 51 are turned off with a Q55 turned on. This binary counter circuit is equal to a conventional one. While in a decrement mode the clock DEC is applied while the clock INC is kept at a high level. Therefore clocks UCP and UCE are kept at high and low respectively. A binary counter consisting of transistors Q42-65 receives the control of clocks CP, CE, DCi and BORROWi. Thus this binary counter is equal to a conventional binary counter circuit.

Title: Existing/standby switching system for power amplifier
Inventor: DOI YOSHIAKI
IPC: H03F3/68
Filed: 1987-09-08
Abstract: PURPOSE:To eliminate the need for a power source only for a switch, a logic circuit for sequence control, and standby route terminating dummy load of the switch by switching and using the power source of a standby power amplifier for the switch in common. CONSTITUTION:If trouble occurs in an existing power amplifier 3, an alarm signal is sent to a transmission system control board 9. The logic circuit in the transmission system control board 9 operates a switch 10 by a power source 10 in accordance with this signal to switch the transmission route to the standby system. That is, the output of a standby power amplifier 5 is connected to an antenna 11. When a response signal of switching completion is sent from the switch 10, the transmission system control board 9 receives this signal and controls a switch 8 to connect the power source 6 to the standby power amplifier 5. Thus, the sequence control is unnecessary, and the logic circuit is simplified, and standby route terminating large-capacity terminator dummy load of the switch is unnecessary.
