Abstract: A spinal treatment method and device are provided. The treatment method includes a catheter introduction step of inserting a balloon catheter into a treatment site between nerves extending from a spine, while being bifurcated, and a lesion area that compresses the nerves; and a treatment step of dilating a balloon, on which anti-inflammatory agent is disposed, of the balloon catheter at the treatment site, and applying the anti-inflammatory agent to the treatment site.

Abstract: A vibration-proof stepping motor of the type having a stator of a built-up construction is disclosed, wherein the stator is composed of a single socket-like stator core member and a plurality of plug-like stator core members assembled with the socket-like stator core member in stacking relation, with stator coils disposed between adjacent pairs of the stator core members. An upper end of the plug-like stator core members which are stacked in the socket-like stator core member together with the stator coils projects from an upper end of the socket-like stator core member. A bobbin of each of the stator coils is resiliently deformable so that the stator is firmly retained by and between upper and lower housings in a compressed condition when the housings are joined together. With the stator thus retained, the stepping motor is free from vibration which would otherwise lead to generation of unpleasant operation noise.

Abstract: A built-up stepping motor includes upper and lower housings each having an internal space and joined together with a support plate disposed therebetween. The lower housing retains therein a stator and a rotor disposed in the stator, while the upper housing holds therein a reduction gear for reducing the output speed of the motor. The output end of a rotor shaft extends through the support plate and meshes with a first gear of the reduction gear. The upper and lower housings are assembled together by interlocking engagement between locking projections and mating holes. A shock-absorbing damper is disposed between two stator cores to protect them against chattering.

Abstract: A copying machine exposure adjustment device, including an operation panel that converts user operations into digital signals, a digital operation circuit that processes operational data from the operation panel and computes exposure data, a D/A converter that converts exposure data sequentially transmitted from the digital operation circuit into analog exposure data, a copy-lamp control circuit that adjusts the light volume of a copying lamp in response to the exposure data from the D/A converter, an image density circuit that detects light reflected from the original document, and a data correction circuit that corrects the exposure data from the D/A converter in response to the image density data from the image density detector circuit while the automatic exposure mode is in operation.

Abstract: A word processing system operates either in a normal display mode or in a layout display mode. In the normal display mode, characters are displayed on a display screen in a size suited for recognizing the contents. In the layout display mode, a full page layout is displayed through the use of symbols which are smaller than the characters in the normal display mode. In a preferred mode, 2.times.3 character positions are included in a block which corresponds to one character size of the normal display mode.
