Title: Camera-type image scanner
Inventor: OGURI MASARU
IPC: H04N5/225
Filed: 1992-11-02
Abstract: PURPOSE:To improve precision or operability at the time of reading a picture by lighting on/off a light source device by means of interlocking it to a mirror operation. CONSTITUTION:For switching between an incident image and an optical path from a photographing lens 16 at the time of photographing, a mirror driving arm 6 rotates clockwise. When rotation proceeds, the arm 6 is brought into contact with a mirror driving pin 5 and clockwise driving force is transmitted to a mirror part. At the same time, a lever rod 9 pushed upward by an ellipse cam 8 rotates clockwise by the traction of a coil spring 12 with a rotary shaft 11 as a center. Thus, a projection 10 provided to the rod 9 is departed from the operation button 23 of an area marker power source switch 22 and an area marker light source 24 turns into an extinguishing state. Then, a mirror 1 is brought into contact with a focusing glass receiver 13, an optical path switching operation is completed and photographing becomes possible. At that time, a lighting window for an area marker provided to the focusing glass receiver 13 is blocked. Then, a scanner stops in a state where it blocks the lighting window at the time of photographing even if an optical finder is mounted.

Title: Pressing method of metallic product and progressive working method
Inventor: NAKAJIMA KAZUO
IPC: B30B13/00
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a shear drop, a broken surface, a burr or the like by pressurizing a metallic material with a pressurizing tool having the outside shape larger than the inside shape of a die, forcing a part of the metallic material into a die to form a thin wall part in the outer periphery of a forcing part and blanking the forcing part with a punch. SOLUTION: A plate shaped metallic material 1 is set on a die 2. The metallic material 1 is forced into the die 2 up to a half way in the wall thickness direction with a pressurizing tool 3 having the outside shape larger than the inside shape of the die 2 to form a forcing part 4, and also a thin wall part 5 is formed in its outer periphery. A blanking punch 6 having the outside shape smaller than the inner shape of the die 2 is lowered from the upper side of the forcing part 4 which is forced into the die 2 up to a half way to blank the forcing part 4. In such a case, since the forcing part 4 is separated from its peripheral thin wall part 5, it is surely blanked even with a weak pressure, and a shear drop, a broken surface, a burr or the like is hardly generated in the outer peripheral surface (separating surface) 12 of the blanked product 11.

Title: Optical parts for forming annular light beam with axis
Inventor: IDESAWA MASANORI
IPC: G02B27/09
Filed: 1985-12-27
Abstract: PURPOSE:To form an annular light beam with an axis easily at low cost by using a lens in the shape of a frustum of circuit cone and making a light beam incident in parallel to the axis of this lens. CONSTITUTION:When the light beam B11 which is thicker than the small- diameter end surface LE 2 of the lens CL in the shape of the frustum o circular cone is made incident from the large-diameter end surface LE 1 so that its axis is aligned with the axis ax of the lens CL, light exiting from the small- diameter end surface LE 2 travels straight as it is to form a light beam Boc corresponding to the axis. Light of the part projecting to the outside of the small-diameter end surface LE 2 is emitted from the part of the conic surface and refracted to generate conic light sheets Bo1 and Bo2. Thus, the annular light beam with the axis is easily generated, so this component is utilized effectively for industrial measurement and as the light source of a sensor for a robot.

Title: Method of controlling frequency of air conditioner
Inventor: YUNAI KAZUHIDE
IPC: F24F11/02
Filed: 1985-12-26
Abstract: PURPOSE:To operate a compressor at a maximum frequency from the starting time and to quickly draw the room temperature near to a set temperature by storing an input current before a certain predetermined time, calculating from the present current value a current value a certain predetermined time ahead and reducing the compressor operating frequency when the calculated current value exceeds the controlled value of the input current. CONSTITUTION:A register 9 detects an input current from a current detector at every predetermined time interval (t). A memory part 10 consists of a plurality (n) of pieces, and stores values read by the register 9, substituting them gradually for new curreent values. At the time t0, current values I-1-I-n are stored in the memory part 10. However, since at a time t1 after a time t2, the register 9 reads in a succeeding new current value, the memory part 10 discards the oldest data I-n, and newly stores I0, and thus current values from I0-I-n+1 are stored. Thus, even when the operational frequency is set at the maximum frequency from the initial time of starting, the operation is carried out at te maximum ability without the operation stop due to interruption.

Abstract: PURPOSE:To attain the high speed and sure seeking operation in the manner of making the resistance torque smaller at the time of seeking operation and also reducing the error in the inclination of a rocking shaft, by forming both tip parts of the rocking shaft to the conical state and providing plural poles on these parts while abutting thereon. CONSTITUTION:A suspension arm 20 carrying a magnetic head 3 on the one end is supported by the rocking shaft 21 so as to be freely rotatably rocked. Then, the constitution is made in such a manner that both tip parts of the rocking shaft 21 are formed to the conical state parts 21a and that both thrust and radial loads are placed by means of providing the plural poles 24 on the inclined surfaces of these parts while abutting thereon. By this arrangement, the deviation in the inclination from an ideal rotary shaft does not occur and the magnetic head is accurately positioned to a desired recording track on the magnetic disk, since the rocking shaft 21 is supported by bearings at the both ends. Also, the resistances at the bearing parts are sufficiently reduced, then the miniaturization of a voice coil motor and the reduction of an average access time by the increase of seek speed are attained.

Title: Sealed hood for molten metal furnace
Inventor: TATSUTA SATOSHI
IPC: C21C5/40
Filed: 1988-11-24
Abstract: PURPOSE:To seal the insides of a furnace body and a hood and prevent a gas pressure from applying the levitating force of the hood to the outside of the title hood, by a method wherein a skirt is formed of an upper flange, a lower flange and a flexible sleeve, interposed between the upper and lower flanges, while the upper and lower flanges are connected by limiting a receded range therebetween. CONSTITUTION:When a converter A is returned to an operating (smelting) position after finishing the pouring of molten steel or molten pig iron, a cylinder 26 is extended to engage with an upper flange 21 and descend the whole body of a skirt 2, however, the push-down force of the cylinder 26 compresses a sleeve body 23 and the force is delivered to a lower flange 22 after the lower flange 22 is abutted against a furnace port flange 53 or a seal packing 54. The sleeve body 23 is flexible and compressible, therefore, the position and the angle of the lower flange 22 can be changed comparatively freely whereby the lower flange 22 may be contacted closely to the furnace port flange 53. A gas pressure in a space A1 in the converter A is increased during smelting, however, a hood B will never be levitated by the pressure increase so that the hood is receded from the lower flange 22 while exceeding a given range and damages the sleeve body 23 since the upper flange 21 is connected to the lower flange 22 through a tie rod 25.
