Filed: 1996-08-17
Abstract: PROBLEM TO BE SOLVED: To possibly reduce protrusion quantity of a plug into a room by providing the prongs of a plug inside of a recess formed on a back face of an inner wall of the house. SOLUTION: A wall face 10 of the house is double-constituted internally and externally by an outer wall 11 and an inner wall 12. The inner wall 12 is provided with an opening, a recess 15 forming a space therein is formed, and an electric receptacle 20 is provided in that recess. The receptacle 20 is connected with a home electric distribution wire at one end, and electrode metal fitting 19 having the prongs for an insertion plug 16 is provide at the other end.

Filed: 1986-10-01
Abstract: PURPOSE:To accurately measure the distance up to an object, by providing a reference voltage setting means for setting a reference voltage level to magnitude exceeding a noise level during a time when a transmission part transmits an ultrasonic wave. CONSTITUTION:Control data is outputted to an ultrasonic wave generating circuit 7 from CPU3 through an I/O interface 6 and the ultrasonic wave generated from the circuit 7 is transmitted to an object 21 according to said control data through an amplifier 10 and a transmitter 1. The reflected wave from the object 21 is inputted to a comparator 9 through a receiver 2, an amplifier 12 and a detection circuit 11. At the time of measurement of a distance, CPU3 outputs reference voltage to the comparator 9 through the interface 6 and a D/A converter 8. The reference voltage is compared with a received signal by the comparator 9 and, when the received signal exceeds the reference voltage, detection data is outputted. The reference voltage level in the comparing part of a receiving part can be made large at the time of the transmission of the ultrasonic wave. Therefore, the noise signal generated by the transmission of the ultrasonic wave does not exceed the reference voltage and a distance can be accurately measured.

IPC: H03M1/08
Filed: 1991-08-22
Abstract: PURPOSE:To reduce the generation of irregular noises due to a DC drift in the output of an A/D converter by extracting a DC component in the output signal of the A/D converter so as to feed back negatively the extracted component to an input, thereby activating a DC servo. CONSTITUTION:This converter is constituted of a D/A converter 36, an integrater 38 and a resistor R2 form a feedback circuit 40 for eliminating a DC drift. That is, the D/A converter 36 converts the output of the A/D converter 14 into an analog signal, the integrater 38 employs an operational amplifier 42 to output a signal resulting from integrating the analog output signal of the A/D converter 14 (the polarity is inverted). The integration signal is fed back negatively to the input of an input buffer amplifier 12 via the resistor R2. Thus, when a DC drift is present in the input buffer amplifier 12 and a comparator, etc., in the A/D converter 14, the DC drift component appears in the output of the integration circuit 38 and it is fed back negatively to the input side. Thus, a DC servo is applied to eliminate the DC drift in the output of the A/D converter 14.

Abstract: PROBLEM TO BE SOLVED: To effectively use a recovered powder coating material by applying charges in the opposite polarity to the charges of a powder coating material which is recovered in a coating process of a powder coating material to use the recovered powder material as a regenerated powder coating material. SOLUTION: In a powder coating process by electrostatic method such as corona method, particles of the powder coating material not deposited on the surface to be coated are collected. The powder coating material consists of a resin for the production of a coating material such as a thermosetting resin e.g. a polyester/urethane hardening resin or a thermoplastic resin e.g. a polyester, and a hardening agent, pigments, additives, and the like. Equivalent or larger charges in the opposite polarity to the charged particles of the recovered powder coating material are added to the particles. When excess charges in the opposite polarity are added, a coating material with charges in the opposite polarity to the charges of the coating layer already formed is applied so that the electrostatic repulsive limit is increased and the film can be formed to a thick film in a dry state.  Thus, the amt. of industrial waste can be decreased, and the cost for the treatment of waste coating material can be decreased.
