Title: Link chain conveyor device
Inventor: OGURA HIROYUKI
IPC: H01J9/227
Filed: 1987-04-01
Abstract: PURPOSE:To prevent the deflection of a chain by transmitting each dead weight of a carrier head and a work to an angle changing roller which is attached onto an angle changing rail by a connecting means and press-attaching the chain onto a sprocket by the reaction force of the angle changing rail, in the captioned device of a panel coating machine for color cathode ray tube. CONSTITUTION:A link chain 1 is traveled by moving rollers 2-4 in sliding with rails 5 and 6. The lower rollers 3 and 4 are transferred onto a sprocket in a sprocket part. A carrier head 8 turns around a supporting shaft 9 and changes angle according to the position of an angle changing roller 15 which shifts along the guide surface of an angle changing rail 10. Each dead weight of a work 7 and the carrier head 8 is transmitted to the angle changing roller 15 through the links 11-13 and an roller supporting plate 14, and the chain 1 is press-attached in the direction of center for the sprocket by the reaction force applied from the rail 10. Therefore, the deflection of the chain can be prevented.

Title: Wavelength conversion element
Inventor: OE KUNISHIGE
IPC: H01S3/11
Filed: 1987-03-31
Abstract: PURPOSE:To extend the range of waves convertible in length by a method wherein a saturable absorption region part and a variable wavelength laser part optically connected therewith are provided and integrated in close on the same substrate. CONSTITUTION:An incident light Pin containing waves absorbed into an active layer 2 is projected onto a saturable absorption region 12, when a light output from the saturable absorption region 12 increases gradually at low rate before a certain time td and then increases rapidly at high rate after td. The td varies dependently on the incident light intensity and the sum I of injection currents I1 and I2 supplied to a variable wavelength laser part 13 is so set as to be 0.94-0.998 times as much as a threshold current Ith of the laser part 13, where the laser part 13 becomes minus in temperature on account of carriers produced by absorption of the incident Pin and therefore a single mode oscillation based on the ratio of the injection currents I1 to I2 starts to oscillate. The oscillating waves can be varied in length within the range of wavelength where the active layer possesses gains by changing the ratio of the injection currents I1 to I2.

Abstract: PURPOSE: To offer a low-alloyed steel, useful as an oil well, pipe line or the like, provided with excellent sweet corrosion resistance, i.e. resistance to corrosion in a wet CO 2  gas atmosphere, by controlling contents of C, Si, Mn, P and S, and adding a specified amount of Cr.  
     CONSTITUTION: The low-alloyed steel consists of up to 0.2% C, up to 1.0% Si, 0.1W2.0% Mn, up to 0.03% P, up to 0.03% S, 0.5W5% Cr and the balance being substantially Fe. The steel may contain 1% or less of one or more of Cu, Ni, Mo and Al, if necessary. In this composition, local corrosion is prevented and an inhibiting effect to sweet corrosion is obtained by the addition of the specified Cr amount. Each element of Cu, Ni, Mo and Al, which is supplementally added at the controlled amount, suppresses pitting corrosion and makes a corroded surface smooth by its conjunct effect with Cr in the coexistence of Cr.

Filed: 1979-06-19
Abstract: PURPOSE: To obtain a three-dimensional structure having many communicating air holes by forming the structure through random attachment of ring ceramics to each other in the captioned structure used for a hot air device and the like.  
     CONSTITUTION: A ring formed body 1 of ceramics is formed by extrusion of temporarily-burnt ceramic material, and after the formed body 1 is wetted with the ceramics slurry having the same composition with the formed body, many of them are thrown in a receptacle for burning at random, dried and burnt therein, thus a united ceramic structure 3 being obtained.

IPC: H02K19/10
Filed: 1991-04-10
Abstract: PURPOSE:To obtain a large torque and reduce the size of a motor by a method wherein teeth provided on the stator and teeth provided on the rotor are geared with each other to generate a torque. CONSTITUTION:Salient poles 14 are provided on the inner circumference of a cylindrical stator 10. Teeth 10a are provided on the inner circumference of each salient pole 14 with a required pitch. Rotor teeth 12a are provided on the outer circumference of a rotor 12 made of flexible magnetic material with the same required pitch so as to be geared with the teeth 10a. A pair of the facing salient poles 14 are used as one unit. At least one pair of the salient poles 14 are excited simultaneously and the excitation of the respective pairs of the salient poles is transferred along the direction of rotation. Along with the transfer of the excitation, the respective teeth of the rotor and stator having the identical pitch change their gearing positions while they are geared with each other. As the attracting forces of the excited poles which operate along the radial direction of the motor can be converted into the rotating force of the rotor, a large torque can be generated.

Abstract: PURPOSE:To reduce a rotational moment acting on a cage by a method wherein radii of curvature of ball grooves in both outer and inner joint members are continuously and gradually decreased from their opening side or deep side toward the deep side or opening side.

Title: Structure of ejector mechanism for metal mold
Inventor: SAITOU SADAYOSHI
IPC: B29C45/40
Filed: 1985-04-12
Abstract: PURPOSE:To prevent generation of galling of an ejector pin and the peripheral surface of a pin hole by a method wherein a gas extracting groove, communicating with atmosphere, is provided on either one of the ejector pin or a holding section thereof. CONSTITUTION:The beginning end of the gas extracting groove 7 is provided at a position slightly apart from the tip end of the ejector pin 2 to prevent the inflow of molding material from a cavity 3 into the gas extracting groove 7. Upon molding, gas, extruded out of the cavity 3, concentrates into the gas extracting groove 7, easy to flow for the gas. The gas extracting groove 7 occupies a space wider than the space of a clearance 5, therefore, the gas, flowed into the groove 7, is released into atmosphere without adhering the peripheral surfaces of the ejector pin 2 and the holding section 4a thereof. Accordingly, the width of clearance 5 between the ejector pin 2 and the pin hole 4 may be kept and generation of galling between the pin 2 and the pin hole 4 may be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce the running cost of a garbage disposal device by discriminating a midnight electric power time zone without using a timepiece circuit and the like. SOLUTION: An optical sensor is disposed at a position where illuminance of an environment corresponding to sunset and sunrise can be detected.

The microcomputer 53 finds a third time centering the first and second times, discriminates a midnight electric power time zone up to a fourth time after a prescribed time from the third time, and a power source switch 56 is made an ON state in the midnight electric power time zone.  A heater 41 constituting an exothermic body heating an stirring tank charging garbage and the like is made a heating state only in the midnight electric power time zone. The stirring tank can be heated even during a time when the heater 41 is made a non-heating state by constituting the exothermal body of an accumulating heater.
