Title: Optical element and scanning optical device using the same
Inventor: KATO MANABU
IPC: G02B13/00
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To excellently correct the movement of an image plane due to internal distortion generated at the time of plastic molding of an optical element by shortening a focal distance calculated from the curvature of lens surface of the optical element, the reffractive index of a material and the thickness in the direction of optical axis than the measured focal distance. SOLUTION: A focal distance in the sub-scanning direction calculated from the curvature of a lens surface of a fθ lens 6, the refractive index of a material and the thickness in the direction of optical axis is made to be shorter than the measured focal distance. Since the lens height of the fθ lens 6 is formed as 9.6mm to the central thickness of 11mm for shortening the molding tact time, the gradient of refractive index is generated inside the fθlens 6 in the sub-scanning cross section. By increasing the curvature of a lens surface R2 on the side of a photosensitive drum surface 8 of the fθ lens 6, the movement of the image plane due to the gradient of refractive index is canceled.  Namely, the refractive power of a lens surface R2 on the side of a photosensitive drum surface 8 of the fθ lens 6 is made to increase and a Gauss image plane 82 is made to locate on the side of an optical deflector 5 than on the side of the photosensitive drum surface 8.

IPC: G11B21/10
Filed: 1990-05-19
Abstract: PURPOSE:To accurately control the oscillation of a swing arm by taking out an elastic member from an open hole for attaching/detaching the elastic member after constructing the entire device and recording the servo-information of the magnetic disk even in a track area beyond the oscillation limit of the swing arm. CONSTITUTION:A swing arm 8 is oscillated from the outside through an open hole for recording the servo-information in a servo-information recording operation device, and the servo-information is recorded in a magnetic disk 6 in the state of moving a magnetic head 14 to a prescribed position. Further, the servo- information is recorded even in the track area (both inside and outside truck areas) of the magnetic disk 6 exceeding the limit of oscillation of the swing arm 8 only by the width L. Like this, the servo-information to the magnetic disk 6 is recorded in the track area exceeding the limit of oscillation of the swing arm 8. Thus, even when the swing arm 8 oscillates by exceeding the limit of oscillation because of such as the malfunction of a voice coil motor 15 or the like, the oscillation of the swing arm 8 is surely controlled.

Title: Burner for liquified petroleum gas
Inventor: OKANO TERUO
IPC: F23D11/38
Filed: 1992-04-23
Abstract: PURPOSE:To avoid a dangerous condition of explosive combustion by a method wherein a shielding valve is separately arranged within a vacancy of a nozzle from a needle valve. CONSTITUTION:Fuel fluid supplied to a burner 1 flows into a vacant part 3 of a nozzle 2. The fluid is injected from a fluid atomization hole 5 of the nozzle 2 into a flame forming part 10 and ignited and burned. When the burner 1 is extinguished or fire is lost in case of emergency state, a control signal from a controller is transmitted to a shielding valve 7 of electromagnetic system, and the shielding valve 7 immediately seats on an inner surface of an end surface wall 4 of the nozzle 2 to shield a flow of the fuel liquid into a liquid atomization hole 5. Due to this fact, fuel is not leaked into the furnace which is being kept at its surplus heated state. In this way, since the flowing-out of the remained fuel liquid into the furnace can be rapidly and positively prevented, the dangerous state of the explosive combustion can be completely avoided.

Title: Phase inversion type variable attenuator
Inventor: TAKAYAMA SHOJI
IPC: H01P1/22
Filed: 1980-09-18
Abstract: PURPOSE:To control the attenuation of a microwave input, by forming a variable attenuator through the connection of a PIN diode between both output terminals of the 1st and 2nd 3dB directional coupler and ground and inserting it between the 3rd and 4th directional couplers. CONSTITUTION:A signal incident to the terminal 1 is equally divided into two signals having a phase difference of 90 deg. with each other, at a 3dB directional coupler 3, and they reach a coupler 4 via a variable attenuator 78 and a synthesized signal appears at a terminal 2. If the bias to a terminal 23 is zero, diodes 9, 10 are turned off and the attenuation is zero. In this case, when a bias current applied to a terminal 24 is increased from 0 gradually, a signal appeared on a terminal 16 is gradually decreased into opposite phase, and the phase of the terminal 2 is inphase to the input to a terminal 15, and an output is obtained, where the two signals are summed. When a current to a bais terminal 24 is zero and the current to a terminal 23 is charged, an output with entirely opposite phase can be obtained. Thus, the attenuation of input microwave signal can be varied with electric control, the output phase can be inverted and electric performance which is excellent can be obtained with small size.
