Title: Controlling circuit for reflection type optical detector
Inventor: MIYAGAWA TOSHIO
IPC: G01S17/04
Filed: 1982-06-02
Abstract: PURPOSE:To detect a reflected light irrespective of a change in the strength of a stray light falling on a light receiving element and the wavelength thereof, by lighting a light-emitting element with a pulse, and by discriminating by a pulse amplifier a signal converted into an electric signal by the light receiving element. CONSTITUTION:A pulse light 8 emitted from a light-emitting element 2 is not reflected because of the absence of a sample and thus does not fall on a light receiving element 3. Therefore, only a stray light 9 from the outside falls thereon. The stray light 9 received by the element 3 is inputted as an electric signal to a pulse amplifier 6. However, this electric signal contains no pulse component, and thus no pulse signal is delivered from the pulse amplifier 6. Accordingly, a pulse discriminator 7 does not operate, and thus a control circuit 10 can deliver a signal of the absence of the sample notwithstanding the incidence of the stray light 9.

Filed: 1994-04-08
Abstract: PURPOSE:To detect knocking per cylinder with a simple structure and high accuracy by detecting ion current generated in the cylinder, differentiating the detected value so as to calculate a judging parameter, and judging generation of knocking when the maximum value during the prescribed period of the judging parameter exceeds a prescribed value. CONSTITUTION:When air-fuel mixture is ignited by means of an ignition plug 2 in compliance with a command from an ECU6, the air-fuel mixture is ionized sufficiently if combustion is in normal condition, so that large ion current flows from a power supply circuit 10 between the center electrode 2a and earth electrode 2b of the ignition plug 2, and a voltage between both ends of a resistance 9 which is detected by the voltage sensor 11 of an ion current sensor 3 is enlarged. Thereby, the iron current is detected, its detected signal is supplied to the ECU6, and its detected current value is differentiated at least once, so that a judging parameter is calculated, and generation of knocking is judged when a peak value during the prescribed period of the judging parameter exceeds a prescribed value.

Title: Manufacture of semiconductor device
Inventor: MAEDA TOORU
IPC: H01L21/306
Filed: 1984-05-14
Abstract: PURPOSE:To reduce unevenness and magnitude of conversion difference when etching an opening to be formed through an insulating film, and to simplify the design as well as to make the pattern fine by causing partial impurity-concentration difference in the insulating film made of silicon oxide on a semiconductor substrate. CONSTITUTION:After a pattern of photo resist 14 is formed on the insulating film 13 made of silicon oxide, etc. which is formed over the semiconductor substrate 11 made of silicon, etc., the insulating film 13a requiring etching is ion- implanted to introduce impurities using this photo resist pattern, so that the etching rate of the insulating film 13a can become faster in comparison with the case where impurities are not introduced. In this way, the etching time can be made short and the conversion difference owing to over-etching can be decreased. Moreover, since the etching rate of the insulating film 13a depends on the kind and concentration of the impurities, controlling of the conversion difference is made possible thereby.
