Title: Valve device
Inventor: OTOME TOSHIOMI
IPC: F16K1/34
Filed: 1980-01-29
Abstract: PURPOSE: To protect a valve from damages and noises due to vibration of the same, by making the fluid flow through the valve stable by forming an edge at a part of the valve body where the boundary layer formed over the surface of the valve body is unstable and separation of the boundary layer tends to occur, located downstereams of the position where the valve body is held in contact with its valve seat.  
     CONSTITUTION: An edge 8 and a recess 9 are formed at the lower end part of a valve body 3. When fluid flows along the surface of the valve body 3 at the time when the valve is opened slightly, a boundary layer of the fluid is formed over the surface of the valve body 3. Here, the edge 8 serves to cause separation of fluid flow positively before unstable separation is not caused due to development of the boundary layer. With such an arrangement, it is enabled to stabilize the fluid flow and to remove fluctuating forces acted to the valve body 3.

IPC: B41J2/44
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To record an image while eliminating deterioration in image quality by correcting the effect of heat generated among a plurality at light emitting parts. SOLUTION: The optical scanner 26 of an image recorder comprises a laser array 30 having a plurality of LD light emitting parts. A laser drive signal for the LD light emitting part is subjected to output timing control by a signal correction circuit 58. Consequently, driving timing at the LD light emitting part is controlled. More specifically, driving timing at the LD light emitting part is delayed by a specified time based on the weighted data of peripheral pixels with reference to an interesting pixel when a pixel adjacent to the interesting pixel is a black pixel.

Abstract: PURPOSE:To make an electro-optical body tube smaller in size as well as to facilitate adjustment of an electron beam by locating part of or whole alignment coils for electron beam projectors closer to the cathode than to the anode of the electron gun. CONSTITUTION:Electrons emitted from the electron gun 1 which consists of the quad electrode 1a, Wehnelt cylinder 1b, and anode 1c made of lanthanumhexaboride are converged by a condenser 3 through the alignment coils for condenser 2.

Title: Pipeline equipped with noise reducing means
Inventor: HASEGAWA KENGO
IPC: F17D1/00
Filed: 1980-01-30
Abstract: PURPOSE: To remove noises from a pipeline, by connecting a flexible pipe joint and a silencer in series to the pipeline, and thereby absorbing vibration of pipes and pulsation of fluid carried through the pipeline.  
     CONSTITUTION: A flexible pipe joint 7 has a diameter substantially equal to the diameter of a pipeline 2 and functions to absorb vibration transmitted via a pipe from the side of a pump 1, so that the vibration is not transmitted to the downstream side of the flexible pipe joint 7. When a series circuit of such a flexible pipe joint 7 and a silencer 8 is added to the pipeline 2 which has caused harmonic vibration, transmission of vibration through the pipe is interrupted by the flexible pipe joint 7 and vibration transmitted by the fluid carried through the pipe is absorbed by the silencer 8. Therefore, noises are not produced from the pipeline.

Title: Transmitter-receiver
Inventor: SHIROSUGI TAKATOSHI
IPC: H04L1/04
Filed: 1987-01-20
Abstract: PURPOSE:To attain stable reception and demodulation without being affected by fading or the like by applying frequency conversion to a signal through the use of a carrier, sending the resulting signal as a transmission signal comprising upper/lower side bands, allowing the receiver side to recover the carrier and to apply the frequency conversion and demodulation to the upper/lower side bands respectively. CONSTITUTION:A data signal a(t) is multiplied with a signal of angular frequency omega0 from an oscillator 4 by a multiplier 2, a PSK signal STX, is fed to a multiplier 3, from which a signal S comprising the upper side band wave SUP and the lower side band wave SLOW is obtained. At the receiver side, the upper side band SUP is separated from the received signal S at a BPF8A and the lower side band SLOW is separated at a BPF8B. The upper side band SUP is fed to a multiplier 9A and multiplied with the signal of angular frequency omegaC outputted from a voltage controlled oscillator 17A. The similar processing is applied to the lower side band SLOW. Thus, even if either reception state of the upper side band wave SUP and the lower side band wave SLOW is deteriorated, the original data signal a(t) is obtained at an output terminal 22 by the other band wave.
