IPC: B29D30/20
Filed: 1987-04-14
Abstract: PURPOSE:To improve the efficiency and safety of exchanging operation by centering the main axis of a forming drum on the main axis of a forming machine in the state where a forming drum is kept on a forming drum keeping holder. CONSTITUTION:A forming drum 3a is transfered to a drum exchanging position C by a transferring carriage 7 and is kept in parallel with a forming drum 3b at the keeping position E for the second drum by the keeping holder 31 for the forming drum. A forming drum 3c is transferred to a drum fitting position B from the drum exchanging position C along the axis A of a main shaft, and the main shaft 2 of a forming machine 1 is inserted into the hollow shaft 4 of the forming drum 3c. While the forming drum 3c is rotated, it is registered, whereby the drum is integrally fitted to the forming machine 1. After the transferring carriage 7 and the forming drum keeping holder 31 having become empty are moved to the drum exchanging position C from the drum fitting position B, the empty forming drum keeping holder 31 is moved to the second drum keeping position E and is kept there, and then the transferring carriage 7 is placed on standby at a drum standby position F.

Title: X-ray tomography apparatus
Inventor: MORI KAZUO
IPC: A61B6/03
Filed: 1990-04-06
Abstract: PURPOSE:To shorten the time required for feeding a body to be examined at the time of collecting the data, to shorten the time for restricting the body and also, to shorten the collection time of plural slice faces by executing a spiral scan with the combination of the movement of an X-ray source and the movement of the body. CONSTITUTION:From an X-ray tube 3, fan beam-like X rays are generated, and an X-ray detector 4 detects the fan beam as one unit. Also, the fan beam can execute not only a 360 deg. rotation but also a ten times continuous or infinite times continuous rotation. Also, while a fan beam is rotating continuously and collecting the data, the body M is moved continuously by a bed driving controller 8. Accordingly to such a constitution, for instance, it becomes equivalent to a fact that the fan beam executes a translation motion in the body axis direction, while rotating against a still body M and the fan beam moves spirally around the body M and collects the data, and the collection time is shortened.

Title: Screw conveyer type automatic machining chip discharge device
Inventor: UMEDA MASASHI
IPC: B23Q11/00
Filed: 1989-04-12
Abstract: PURPOSE:To prevent impossibility of rotation due to invasion of machining chips between a screw and the bottom plate by fitting one of a screw and a bottom plate of an inclined surface bottom portion surrounding the lower side of the screw in such a manner as to displace up and down with respect to the other thereof, and fitting a screw bearing to the outside of a bed. CONSTITUTION:Usually, a screw 18 is rotated in a posture of contacting the upper surface of a bottom plate 14, so that machining chips are hard to enter therebetween. If a block-like machining chip such as a cut chip of a falling matter or a stem which is a cut material dropped due to failure of carry-out operation enters between the screw 18 and the bottom plate 14, the screw 18 connected to a driving shaft 24 through a universal coupling 22 is displaced upward together with a shaft 20. That is, when a cut chip enters, the screw 18 is floated through the universal coupling, and rotated in a floating state to continue the action of discharging the machining chips. Furthermore, as the bearing of the screw 18, that is, the bearing 26 of the driving shaft 24 is installed outside the bed, the bearing is kept free from the influence of machining chips discharged on the screw 18.

Title: Reproducing device of magnetic sheet
Inventor: TATEISHI KENJI
IPC: G11B5/02
Filed: 1980-07-07
Abstract: PURPOSE:To assuredly prevent the lowering of the reproduced signal, by giving the  compensation to the level of reproduction caused by the difference of the shift linear speed of a magnetic head or to the variation of the frequency characteristics. CONSTITUTION:When a turntable rotates, a head attaching table shifts in the radius direction. Accordingly the resistance value of a potentiometer changes. If a resistance 45 is defined as a potentiometer, the gain of an amplifying circuit can be varied by the resistance value of the potentiometer. When a potentiometer is inserted in parllel or in series to the resistance 44 or 45, not only the gain but the frequency characteristics can be controlled. Both the record/reproduction level and the high-range characteristics are lowered at the part of a head where the shift linear speed is low. In this connection, the change of resistanc value is set for the potentiometer in order to increase the degree of amplification to the high-range frequency.

Abstract: PURPOSE:To facilitate a process and to make positioning accurate relatively to an optical element by using a photosensitive thin film which increases in transmissivity when irradiated with an electron beam or ion beam. CONSTITUTION:A substrate 11 uses a glass plate which has ITO for charge-up prevention against an electron beam 15 or ion beam on the surface and the photosensitive thin film 12 use a mixture of a natural polysaccharide body such as pulran and a diazo compound. The substrate 11 is coated with the photosensitive material 12 and CMS electron beam resist 14 which has a lower sensitivity than the photosensitive material in that order. Then, an irradiation quantity distribution is given by the electron beam 15 so as to correspond to the phase shift function of a Fresnel lens whose periphery is rectangularly clipped and a development process is carried out to vary the film thickness of the resist 14, thereby forming a Fresnel lens array 13. Thus, a light shield film is simultaneously formed with lenses, so the process becomes extremely simple and the accuracy of the positioning between the lens array 13 and light shield film after completion is improved.

Abstract: PURPOSE:To stably display map data easy to see by setting an extended area obtained by extending a region including the position of a moving body to a prescribed range and omitting to read map data of adjacent maps for display processing into a memory at the time when the moving body exists in the extended area. CONSTITUTION:A drawing device 6 draws a map based on map data from a memory 5 and the direction and the position from a position detector 2. When the moving body exists at a point (a) of map data F, regions A, B, C, E, F, G, I, J, and K are displayed with the region F as the center. In this display state, an extended area F1 indicated by a dot line around the center region F is set. While the moving body exists in the extended area F1, map data is not read into the memory 5; and when the moving body goes out of the extended area F1, map data is read for switching. Then, a next extended area K1 is set. As the result, map data is made easy to see and is stably displayed.

Abstract: PURPOSE:To reduce cost by pressing either of two push button switches to indicate a turning direction and pressing both of said switches causing both right- and left-turn indication lamps to be turned on and off simultaneously to indicate a hazard when riding a bicycle. CONSTITUTION:When a passing switch 20 is pressed, head lights 16, 17 are electrified and turn on and off serving as passing lights.

When both of the push button switches 18, 19 are pressed, both of the right- and left-turn indication lamps 14, 15 are turned on and off, serving as a hazard indicator. And further, if either of the switches 18, 19 is pressed, a lighting on-off circuit 13 is disconnected from the passing switch 20, causing the head lights 16, 17 to fail to function as passing indicators, and the turning on and off of the turning direction indicating lamps 14, 15 takes preference. Thus, the system becomes simple, reducing the cost.
