Title: Cleaning device
Inventor: TAKAGI ATSUSHI
IPC: G03G21/10
Filed: 1983-12-24
Abstract: PURPOSE:To attain a good cleaning capacity by providing a cleaning member, which can be taken into and out from an aperture part of a scraper member, to remove foreign matters such as flocculation of a developer, paper powder, etc. clogged a part near the scraper. CONSTITUTION:A magnetic developer remaining on a free end part 17a of a scraper member 17 passes an aperture 17c and is gathered by a magnet roll 12. Since the aperture 17c of the scraper member 17 is clogged with foreign matters such as the developer, flocculation, paper powder, etc. by the long-time use, the aperture 17c is cleaned by a cleaning brush 18. When a photosensitive drum 1 is rotated, power is supplied to a solenoid 19, and the cleaning brush 18 is moved to a position distant from the aperture 17c not to hinder the flow of the developer passing the aperture 17c. When the drum 1 is stopped, power supply to the solenoid 19 is cut off, and the front end part of the brush 18 is moved forward by the action of a spring incorporated in the solenoid and is inserted into the aperture 17c and is stopped.

Title: Semiconductor integrated circuit for fdd
Inventor: YAMAMOTO MINEHISA
IPC: G11B19/02
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To greatly reduce the recovery time of the transition from an erasing to a reading by putting the data reproducing device in its operable condition after the erasing current is turned off and then, putting the data output device in its operable condition. SOLUTION: When a transition is made from an erasing to a reading operation, a controller 4 turns off a control signal XEG and then turns off a control signal XDEG after a prescribed time T1 is passed. Them, the signal XDEG is turned off after a prescribed time T2 is passed and a control signal Pre. Cont, which was turned off during the erasing, is turned on. Then, a control signal RDEN is turned on after a prescribed time T3 is passed. Note that a data reproducing circuit 1, which was in its inoperable condition during an erasing, is made operable after an erasing current Ier is turned off and the time T2 is passed. Therefore, if the time T2 is properly set, the recovery time from an erasing to a reading is reduced to within 100μs, for example.

Title: Conductor roll and electroplating device
Inventor: YOSHIMURA SATORU
IPC: C25D7/06
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent deposits on the surface of a conductor roll of an electroplating device for a steel strip from adversely affecting a steel sheet by providing the surface of this roll with many grooves. SOLUTION: The surface of the conductor roll 1 is provided with the vertical grooves 2. The width of the vertical grooves 2 is set at 2.0 to 3.0mm wide slightly larger than the max. diameter of about 1.0mm of the grinding powder and sludge generated from a roll polisher. As a result, even if the sludge and grinding powder intrude between the conductor roll 1 and the steel sheet, the grinding powder and sludge enter the inside of the vertical grooves 2 and are expelled in a progressing direction and are thus prevented from meshing between the conductor roll 1 and the steel sheet and, therefore, the generation of pushing flaws at the steel sheet does not arise. The surface is easily cleaned and the sludge in the grooves 2 is expelled by using a brush-like polisher 5 rotating in the groove direction in common and, therefore, such use is preferable.  Horizontal grooves may be formed in place of the vertical grooves 2.

Title: Start id recording method for rotary head type digital audio tape recorder
Inventor: EJIMA MAKOTO
IPC: G11B20/10
Filed: 1989-09-25
Abstract: PURPOSE:To surely detect the head of a music at the time of high-speed search using a start ID, and to execute fade-in reproduction by recording the start ID at the same time that fade-in recording is started whether a sound signal exists or not. CONSTITUTION:A recognition circuit 32 decides whether a fade-in key 31 was inputted or not. When it is decided that the key 31 was inputted, a recording level is let down to the lowest level by a digital volume 33, and the start of the recording is instructed. Simultaneously with this, a microcomputer 36 instructs the recording of the start ID through a start ID recording instruction circuit 34. Next, the recording level is raised gradually, and the recording is shifted from the fade-in recording to the usual recording. Thus, the start ID is always recorded at the time of the start of the recording whether the sound signal exists or not.

Title: Input circuit
Inventor: MATSUMURA TAKASHI
IPC: H03K19/018
Filed: 1985-11-07
Abstract: PURPOSE:To obtain an input circuit which receives the reduced effect of the disturbance compared with a conventional input circuit and secures high accuracy despite the high residual potential of an input terminal, by providing the two stages of diode-connected transistors at an input part together with another transistor which forms a mirror circuit. CONSTITUTION:When an input terminal 1 conducts with the minimum potential, the current I1 of a constant current source 7 is branched to the terminal 1, a resistance 6 and input transistors (TR)9 and 10 respectively. Here a switching TR5 is kept OFF while the emitter current flowing through the TR10 has a level larger than the load current (current I2 of a constant current source 8) of an input inverting TR4. Then the TR5 is turned ON when the emitter current flowing through the TR10 is smaller than the load current of the TR4. Thus it is possible to decide a conductive or non-conductive state of the terminal 1. Furthermore the effect due to the variance of the current amplification factor of the TR4 can be reduced owing to a mirror circuit constitution of an input part.

Abstract: PROBLEM TO BE SOLVED: To cut an optical fiber exclusive of the specified optical fiber project ing amt. necessary for end face polishing in a connector ferrule state by using a spring for adjusting the depth of cut of a cutting blade for the optical fiber behind this cutting blade. SOLUTION: A collar contact part 5a to be pressed to a ferrule collar part and plural guides 5b paralleled to introduce the outer periphery of the ferrule in a longitudinal direction are formed at a sliding plate 5. The cutting blade 2 may be abutted perpendicularly against the fiber in its axial direction by this collar contact part 5a and the paralleled plural guides 5b. The specified projecting amt. necessary for end face polishing is determined by the relation between the ferrule part size from the ferrule collar part to the ferrule end face and the size from the collar contact part 5a of the sliding plate 5 to the cutting blade 2 and, therefore, this amt. is previously so set and built as to attain the optimum fiber projecting amt. The sliding plate 5 has a mechanism to make the plate slidable in a horizontal direction with respect to the cutting blade 2.
