Abstract: PURPOSE:To reduce spurious radiation and to improve disturbing wave excluding capability by applying band limit and automatic gain control to an input signal and providing an input circuit amplifying in push-pull the output before the 1st mixer circuit. CONSTITUTION:An input signal from terminals 12, 13 is selected by a changeover switch section 11 in a TV signal receiver of broad band such as a CATV and fed to an input circuit section 14. The circuit 14 uses an LPF to band-limit the input signal, applies automatic gain control, the output is amplified by a push-pull amplifier to suppress the secondary intermodulation distortion and fed to a mixer 17 through a BPF. The mixer 17 uses a signal from a fixed frequency-division circuit 16 and the 1st local oscillator 15 constituting a PLL to convert the input signal to a frequency higher than the input frequency and the result is fed to the 1st intermediate frequency circuit section 18. The circuit 18 applies band limit to the signal from the mixer 17, amplifies it and transmits the result to a mixer 20, where the signal from the 2nd local oscillator 19 applies frequency conversion to the signal from the circuit section 18, transmits it to the 2nd intermediate frequency circuit section 21, and the circuit 21 applies band limit and outputs the signal with amplification.

Abstract: PURPOSE:To obtain different scanning speeds at the same speed by providing plural  plane polyhedral mirrors each of which has plane reflecting faces and plural concave  polyhedral mirrors each of which has the different number of faces from that of the  plane polyhedral mirror, and equalizing the curvature of the concave face with each normal angle of revolution of both the plane and concave faces. CONSTITUTION:A plane polyhedral mirrorIwith n faces and a concave polyhedral  mirror II with m faces are provided. When a straight line (a-b) is demoted as the  plane polyhedral mirrorIand a curve (a-d-c) is regarded as the concave polyhedral  mirror II in the drawing showing a part of these polyhedral mirrors, a straight line  (O-Q1) with an angle theta' from a straight line (O-a) is the normal of the plane polyhedral  mirrorIwhen a double rotation polyhedral mirror rotates by an angle theta' and similarly  a straight line (O-Q2) with an angle theta'Xm/n from the straight ine (O-a) is the normal  of the plane polyhedral mirrorIwhen the double rotation polyhedral mirror rotates by  theta'Xm/n. Therefore, theta'Xm/n is the normal angle of rotation of the plane polyhedral  mirrorIat that time. Since the normal angle of operation of the plane polyhedral mirrorIis equal to that of the concave polyhedral mirror II, the concave polyhedral mirror II has the scanning speed m/n times larger than that of the plane polyhedral mirrorI.

Title: Oil lubrication type air compressor
Inventor: HOTARI ISAO
IPC: F04B39/02
Filed: 1991-06-26
Abstract: PURPOSE:To prevent oil from being deteriorated by enlarging the capacity of enclosed oil and also lessening the quantity of condensed water produced in an oil reservoir. CONSTITUTION:This is an oil lubrication type compressor which is characterized by the provision of an oil separator in an air tank 46. When the oil separator is disposed in the air tank, the capacity of an oil reservoir can be made small and the capacity of enclosed oil can be enlarged.
