Title: Polishing method
Inventor: NAGASE NOBORU
IPC: B24B51/00
Filed: 1986-04-09
Abstract: PURPOSE:To aim at improvement in polishing efficiency, by having a polishing route, moving a grindstone along a work surface, stored in a memory device, and reciprocating this stone repeatedly as much as the preset time or frequency along the stored route. CONSTITUTION:When a moving direction detecting signal is outputted, it is inputted into a central process unit 101 whereby a driving signal is outputted to a moving motor, and a wheel head is moved as far as the specified distance in the specified direction by operation of the motor. Simultaneously with this movement, an equal signal is outputted to a random access memory from the central processing unit, only positional data are stored as grinding route data irrespective of a copying speed. Next, a machining mode is selected by a mode selector switch 71 of a control plate 57, and total time for a machining process is designated by a time designating part 84. Under this state, if a start switch 86 is pressed, the polishing route data are read to the CPU from the RAM, whereby the moving motor is driven and the grindstone is reciprocated along the polishing route as long as the specified time, thus a work is ground.

IPC: B41J2/01
Filed: 1986-04-09
Abstract: PURPOSE:To reduce the number of parts for a recovery device, minimize space and reduce cost by allowing a cleaning blade to protrude when a motor for actuating the sequential operation of an ink suction means rotates in one direction and the cleaning blade to stop at a retreating position when the motor is reversed. CONSTITUTION:When a line feed motor 1 rotates, a gear with a dowel 21 turns and the dowel is fitted to the rear end 25 of a cleaning blade 24, which is, in turn, enabled to protrude in the direction of a carriage 2. A claw 28 pushes down the claw 30 of a holding lever 29 which, in turn, retains the cleaning blade 24 at a protruded position. The carriage 2 is moved in the direction of a platen 6 and a blade 32 attached to the tip of the cleaning blade 24 is caused to wipe off the ink discharge outlet surface of a recording head 1A-1D. While the claw 30 is positioned between a pair of resetting claws 33, 35, the motor 18 is reversed to return the gear 21 with a dowel to an initial condition.

Title: Vibrating mirror device
Inventor: SAITO HIDEMI
IPC: G02B26/10
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate the vibration transmission of a main body device such as a camera and to prevent blurring from occurring by providing a vibration shock absorbing means which absorbs a vibration shock generated by vibration. CONSTITUTION:When the nut 37 of an adjusting rod 36 is tightened up, an adjusting screw 39 is drawn, spring supporting arms 31L and 31R rotate inward, and body-side energizing springs 32L and 32R are increased in tensile force associatively. As for an angular vibration system like this, it is considered that as the spring force is increased, the spring constant (k) of the intrinsic vibration frequency (intrinsic circular vibration frequency) omega=k<1/2>/J of the angular vibration system by a spiral spring is increased in inverse proportion to the length of the spiral spring, so that its intrinsic vibration frequency is increased. When the nut 37 is loosened, on the other hand, the energizing springs 32L and 32R are decreased in tensile force and the intrinsic vibration frequency is decreased as well as when the length of the spiral spring is increased. Thus, vibration shock absorbing means 31 - 39 which absorb the vibration shock force generated by the vibration of a reflecting mirror 60 are provided to obtain the vibrating mirror device which does not transmit vibration to the main body device such as a camera.

Title: Circulating pump controlling circuit for heating apparatus
Inventor: WATANABE KIICHI
IPC: F24H9/20
Filed: 1980-06-18
Abstract: PURPOSE:To prevent reduction of heating rate and shorten the time necessary for heating liquid by installing two thermometers at the upper and the lower layer parts of a tank without setting a fixed temperature and driving a circulating pump when the temperature in the upper layer is higher than that of the lower layer. CONSTITUTION:When the voltage V1 of the detector S1 arranged in the upper liquid layer in a tank 1, namely the temperature of the upper layer liquid is higher, and the voltage V2 of the detector S2 arranged in the lower liquid layer in the tank, namely the liquid temperature in the lowr layer liquid is lower, thoe voltages are entered into a comparator CR, and H signal is transmitted from the comparator CR. Then, a transistor TR is turned ON, and a relay R is operated, and a circulating pump P is driven to recover the warm liquid heated by a heat exchanger 4 into the tank. Thus, even if the temperature is below a fixed temperature, when the liquid temperature in the upper part is higher than the liquid temperature in the lower layer part, the circulating pump P is driven and the warm liquid is recovered in the tank 1, so the temperature of the liquid can be raised in a short time with high efficiency.

Title: In-line type electron gun
Inventor: YAMANE HISAKAZU
IPC: H01J29/50
Filed: 1986-04-08
Abstract: PURPOSE:To prevent to generate a convergence drift, as well as correct a deflecting aberration, by forming vertical electrode pieces of both side quadrupole electrodes in different shapes, and forming the central quadrupole electrode symmetrical while composing the both side quadrupole electrodes asymmetrical. CONSTITUTION:While four sheets of electrode pieces of the central quadrupole electrode 2 are formed axis-symmetrical to the vertical and horizontal axes Y2 and X, both side quadrupole electrodes 1 and 3 are made asymmetrical to the axes Y1 and Y3 although symmetrical to the horizontal axis X. Since the form of the central quadrupole electrode 2 and that of the both side electrodes 1 and 3 are different, the actions of the quadrupole lens to the central electron beams 5G and to the both side electron beams 5B and 5R are also different, resulting in a different action in the axis X direction to the both side electron beams 5B and 5R. Therefore, a convergence drift generated in case that an axis-symmetrically formed quadrupole electrode is used is set off, and the drift can be eliminated.

Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To provide the manufacture of a synthetic resin lining pipe, capable of more reliably preventing air from staying between a metal pipe and a synthetic resin pipe as compared with a conventional method. SOLUTION: A heat-expandable synthetic resin pipe P is inserted into a metal pipe M with a bonding agent B between them, and the diameter of the synthetic resin pipe P is expanded with the aid of a heater 2 to bring it into close contact with an inner face of the metal pipe M. In this case, by applying vibration (through vibrating plate 3) to the body to be heated under heating by means of the heater 2, the frictional resistance between the metal pipe M and the synthetic resin pipe P is reduced, and the inhibiting factor of shaft shrinkage is eliminated to make the creation of diametral expansion reliable.
