Title: Thin-film dry etching apparatus
Inventor: TSUJII KANJI
IPC: H01L21/302
Filed: 1987-04-20
Abstract: PURPOSE:To measure the thickness of a natural oxide film accurately at an Angstrom level and to judge whether the natural oxide film is present, by bringing a conductive probe very close to the vicinity of a substrate to be treated, and monitoring a tunnel current, which flows between the substrate and the probe when a voltage is applied across the substrate and the probe. CONSTITUTION:A step for removing a natural oxide film on the surface of a substrate is conducted. After the surface treatment step has been conducted, the substrate 3 is conveyed into a measuring chamber 2 for measuring a tunnel current. At this time, the supply of etching gas from an introducing port 4 is stopped, a partitioning wall 8 is opened and the substrate 3 to be treated is conveyed into the measuring chamber 2. In the measuring chamber 2, the distance between the substrate 3' and a metal probe 9 is brought close by about 1 nm by the working of an voltage actuator. A bias voltage in the range of 1 mV-several V is applied across the probe 9 and the substrate 3' to be treated, and the tunnel current, which flows between both parts, is measured. The tunnel current is largely fluctuated even if the natural oxide film (insulating film) is in an Angstrom order depending on whether the film is present or not.

Title: Radio receiver
Inventor: KEGI KAZUHIKO
IPC: H04B1/16
Filed: 1990-04-12
Abstract: PURPOSE:To prevent the occurrence of a silent waiting time by providing first and second receivers and operating the BSM(best station memory) function by a non-selected receiver at the time of operating this function and switching and controlling the demodulation after the end of the operation. CONSTITUTION:Even when the execution command of the BSM function, the preset recall, etc., is issued during the regeneration of a demodulated audio signal in a first receiver TUN1, the BSM function, or the preset recall is executed by the second receiver TUN2. After the second receiver TUN2 is set to the reception state, a control signal CTL is sent to an electronic volume 33 by a central operation circuit 36, and the electronic volume 33 fades out the output of reproduced sounds from the first receiver TUN1 and fades in the output of reproduced sounds from the second receiver TUN2. Thus, the silent waiting time is eliminated.

Title: Switch input circuit
Inventor: KATSUMI CHIAKI
IPC: H03K17/62
Filed: 1980-07-10
Abstract: PURPOSE:To simplify circuit constitution by constituting a circuit so that only one signal terminal is used to set two switches. CONSTITUTION:For example, on states of switches 1-1 and 1-2 correspond to 0s, and off states to 1s. When inputs are both 1s, a potential VIN at a terminal 4-3 is a half as high as a power voltage Vcc. Therefore, transistor TRs 6-1, 8-1, 9, 6-2, and 8-2 turn on and outputs OA and OB are 0s. When the inputs are a 0 and, the TRs 6-1, 8-1 and 9 turn off, and the TRs 6-2 and 8-2 turn on, so that the outputs OA and OB are a 1 and a 0, respectively. When the inputs are the 1 and a 0,  the TRs 6-1, 8-1 and 9 turn on, and the TRs 6-2 and 8-2 turn off, and outputs OA  and OB are the 1 and 0. Further, when the both are the 0s, VIN= Vcc/2, and the  outputs OA and OB are both the 0s as well as when the inputs are both the 1s.  Thus, only one signal terminal is used for two switch set states, so the number of terminals is decreased, thereby simplifying the circuit constitution.
