Abstract: PURPOSE:To obtain a stable picture quality in either monochromic mode or multicolor mode by providing an image forming condition setting means which sets image forming conditions different in the monochromic mode and the multicolor mode to first and second latent image forming means and/or first and second developing means. CONSTITUTION:When a mode switching means 32 is set to either of the monochromic mode, an electrifier 12 uniformly electrifies a latent image carrier 10 in response to latent image formation and according to instructions from the image forming condition setting means 34.

Title: Sliding contact material
Inventor: TAKIGUCHI FUJIMATSU
IPC: H01B1/02
Filed: 1983-06-08
Abstract: PURPOSE:To improve the wear resistance of a conventional sliding contact material consisting of Pd and Ru by adding specified amounts of Sb and one or more among Si, Bi, Ge and Ga to the contact material. CONSTITUTION:An alloy material having a composition consisting of, by weight, 87-93% Pd and 7-13% Ru has been widely used up to now as a sliding contact material, especially as a material for a brush contact. A brush contact of the alloy material shows, however, inferior wear resistance during sliding along a commutator and causes the generation of noise. In order to improve the wear resistance, 1-10% Sb and 0.5-3% one or more among Si, Bi, Ge and Ga are added to the alloy material without changing the ratio in the composition. 0.01- 0.5% Fe group metal may be further added.

Title: Road surface state detecting device
Inventor: KUNO TETSUYA
IPC: G01B21/00
Filed: 1995-04-26
Abstract: PURPOSE: To detect the surface state of a road by collecting a traveling sound due to friction between the tires of an automobile and the surface of a road, dividing the sound signal of the collected sound in each frequency band by a sound processing means and then comparing the processed result with a stored road surface state map. CONSTITUTION: A sound collecting means 1 collects a traveling sound due to friction between the tires of an automobile and the surface of a road and converts its sound signal into an electric signal. A sound processing means 3 separates the sound signal in each different frequency band. When it is defined that output signals from respective BPFs 6 to 8 are S1 to S3 and their output signal values are s1 to s3 , the means 3 outputs the values s1 to s3 of the signals S1 to S3 to a comparing/judging means 4. A road surface state storing means 5 stores sound information on a three-dimensional (3D) coordinates consisting of the values s1 to s3 in each different road surface state as a distinguishable table. The means 3 compares which road surface in the 3D coordinates stored in the means 5 corresponds to each of the values s1 to s3 obtained from the means 3.  When the signals of the values s1 to s3 correspond to a certain road surface state, e.g. a wet road surface state, stored in the means 5, the means 4 judges that the road surface is wet.

Title: Slack corrector for cassette tape
Inventor: TAZAWA TOSHIO
IPC: G11B15/675
Filed: 1979-08-13
Abstract: PURPOSE: To automatically correct the slack of cassette tape, by winding the slack of tape through giving the low-voltage driving command toward rewinding direction to the motor for a given time, with the reel turntable in brake condition.  
     CONSTITUTION: When the cassette is loaded and the cassette loading detection switch SW is ON, the monostable multivibrator OSM is triggered, and the emitter voltage of transistor Q2 is more lowered than usual output voltage. The other output of the OSM switches on the transistor Q3. Since the fast traverse input terminal F is at low, the rewinding motor M performs low-speed rewinding. The brake force of the rewinding reel turntable is weak for the clockwise direction and strong for the counterclockwise direction. Then, the brake of the fast traversing reel turntable has inverse characteristics. Since the reel turntable of cassette tape is in braking state,  the turntable winds with weak torque while the presence of slack to the tape and  stopped without slack. Accordingly, the slack of tape can automatically be corrected.
