Title: High frequency signal converter
Inventor: YOKOBORI SEIICHI
IPC: H04N5/00
Filed: 1989-09-14
Abstract: PURPOSE:To prevent leaked harmonics from a through-path from being inputted to a frequency conversion circuit at a terminal equipment by constituting a directional buffer circuit with an active element. CONSTITUTION:An input terminal 32 connects to a distributer 34 and one distribution output section of the distributer 34 connects to a frequency conversion circuit 35 and the other distribution output section connects to a buffer circuit 36 forming a through-path. The buffer circuit 36 is a directional amplifier using an active element and a high frequency signal from the input side is sent to an output terminal without attenuation, but the signal is not almost leaked to the reverse direction. Then even when an output of a local oscillator of a VTR or an FM receiver is leaked to an antenna terminal and is going to the distributer 34, it is blocked by the buffer circuit 36.

Title: Method of surface hardening treatment for titanium material
Inventor: OGAWA ATSUSHI
IPC: C21D1/06
Filed: 1994-10-04
Abstract: PURPOSE: To easily form a thick surface hardened layer without causing surface roughness by subjecting a titanium material to heating treatment at a prescribed temp. in an atmosphere under specified gaseous CO2 partial pressure and thereafter subjecting the same to heating treatment at a high temp. in an inert gas. CONSTITUTION: A titanium material is heated to a prescribed heating temp., preferably, to >=700 deg.C in an atmosphere in which gaseous CO2 partial pressure is regulated to >=1/20 atmospheric pressure or in an atmosphere in which CO2 partial pressure is regulated to >=1/20 atmospheric pressure, and the balance is inert gas or gaseous N2 , or a gaseous mixture thereof. Thus, O and C are infiltrated into the titanium material to harden the surface. After that, the titanium material is furthermore subjected to heating treatment at the same heating temp. or above in an inert gas or in a vacuum. Thus, the infiltrated O and C are diffused to the inside to form a thick hardened layer small in surface roughness.  In the case of an (α+β) type or β type titanium alloy material, the hardness of the base material can be increased by executing age hardening treatment after the same two stage heating treatment.

Title: Ink jet recorder
Inventor: MORIYAMA JIRO
IPC: B41J2/175
Filed: 1985-10-29
Abstract: PURPOSE:To shorten a discharge cycle to perform recording at high speed by providing a means to prevent the back flow of ink to an ink supply side before and after a discharge pressure generating means. CONSTITUTION:A through hole 5A is provided in the center of a piezoelectric element 5 and is closed by a valve 4A on the nozzle 2 side. A valve 4B is also provided behind the piezoelectric element 5 in such a way as to shut off a flow channel. The valves 4A, 4B are so constituted as to allow ink to flow only to the right, thus contributing toward the planned formation of a pressure chamber 1A, 1B. If a drive signl is transmitted, the piezoelectric element 5 is deformed on the pressure chamber 1A side, causing the pressure of the pressure chamber 1A to mount with ink droplets 7 discharged from the orifice of the nozzle. At the same time, a negative pressure generates in the pressure chamber 1B, opening the valve 4B to allow the ink to flow into the pressure chamber 1B. If the piezoelectric element 5 is restored to its original position, the valve 4B closes and the valve 4A opens, thus preventing the back flow of ink from the pressure chamber 1B. At the same time, the ink flows into the pressure chamber 1A through the valve 4A, so that the restoration of a meniscus at the nozzle tip is expedited and the discharge cycle shortened for fast recording.
