Filed: 1984-12-19
Abstract: PURPOSE:To eliminate a disturbing signal at a lower area of a VTR according to a cubic distortion by providing a filter to equalize a band width of an upper wave area of a signal supplied to a magnetic head with a band width of a lower wave area. CONSTITUTION:A filter 15 attenuates signals <=1.6MHz and >=8.4MHz.

A band width of the upper wave area is 3.4MHz between 5MHz and 8.4MHz. Because this filter 15 equalizes almost the upper and lower band width of the FM luminance signal YFM which is supplied to the recording head, a cubic distortion when occurred in the area between and FM carrier of 5MHz and the upper wave area (5-8.4MHz) produces a signal of 1.6-5MHz at the lower wave area and does not produce a signal at the lower part of 0-1.6MHz.

Filed: 1990-10-09
Abstract: PURPOSE:To achieve an accurate judgment by utilizing correlation between a light-inputting means and a member for judgment and constituting so that a signal for judging a member to be measured is generated at a light-output means. CONSTITUTION:Rays 9a and 9d out of rays 9a - 9d from a light source 7 pass through a polarization plate of a member for judgment 8 and at the same time pass through 1/2 phase plates 2a and 2b, thus enabling a straight polarization to be converted to a straight polarization which crosses it at right angle. Therefore, the rays 9a and 9d are displayed as being bright at judgment signal display parts 5a and 5d through the polarization plate of the member 8, the phase plates 2a and 2b, and a polarization plate 3. Also, the rays 9b and 9c pass through a deflection plate of the member 8 but are shut off by the polarization plate 3 of a light input means 4. Therefore, they are displayed as being dark at the judgement signal display parts 5b and 5c, where the bright and dark displays at the display parts 5a - 5d are utilized as H and L of digital signal. The H and L signals determine whether a member to be judged 1 is true or not.

Title: Joint structure for propulsion pipe made of synthetic resin
Inventor: UJIHARA KIWAMU
IPC: F16L15/04
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To improve workability and a water cut-off property. SOLUTION: A taper surface 26 is formed on an inner surface of an end part of a socket 14 and a rubber ring 30 is compressed between the surface 26 and a base end part of a spigot 16. When the spigot 16 is joined to the socket 14, the ring 30 is not compressed just until the spigot 16 has been screwed in or just until a stopper surface 24 abuts on the base end part of the spigot 16. This reduces joining resistance and prevents the ring 30 from twisting. Because a space for storing the ring 30 is secured by the surface 26, a rubber ring of a common size can be used in the event of a small-bore and thin-walled pipe.
