Title: Disk motor control circuit
Inventor: HOSHI TERUO
IPC: G11B19/247
Filed: 1986-06-20
Abstract: PURPOSE:To prevent abnormal rotation of a disk motor by providing an EFM presence detecting circuit detecting the presence of an EFM signal, a gate circuit, an intermittent acceleration circuit and a counter. CONSTITUTION:If the EFM signal is lost due to any fault, a detection signal representing loss of EFM signal is generated from an EFM signal presence detection circuit 15 and controls a gate circuit 10 to interrupt a signal from a phase servo and a rough servo and a disk motor is coasted slowly in a decelerated speed. When the detection signal representing loss of EFM signal is generated, intermittent acceleration circuits 12, 17 to drive the motor forward at a prescribed interval thereby driving the disk motor which may be at halt. While a rough servo generating an acceleration signal is selected, if the decelerated signal is generated still after a prescribed time based on a counter 32, it is judged that a faulty state in which the disk motor is not decelerated is present, to inhibit the deceleration signal.

Abstract: PURPOSE: To greatly reduce the frequency of the occurrence of and the length of the waiting time by measuring the surface potential of an electrostatic latent image carrier at a fixed time-interval, and executing AIDC(automatic density control) only when the amount of change from the previous measurement value exceeds a specific value. CONSTITUTION: A potential sensor 44 for measuring the potential of the surface of a photoreceptive drum 41 and an AIDC sensor 210 for detecting the density of a reference toner image formed on the drum 41 at the time of the AIDC are disposed around the drum 41. The surface potential of the photoreceptive drum 41 after electrification and its damped potential after exposure are measured by the potential sensor 44, to be stored in a printer control part. Subsequently the surface potential and damped potential measured by the potential sensor 44 are compared with previously measured values stored in the printer control part. Only when the amount of change from the previous measurement value exceeds the specific value, the AIDC is executed, and when unnecessary, not executed. Thus, the time required for the processing can be shortened.

Title: Controller of composite driving system of vehicle
Inventor: HATTORI NOBORU
IPC: B60K17/04
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To secure the accessory function and prevent the responsiveness at re-acceleration from decreasing in a fuel supply stop state at deceleration. SOLUTION: In a controller of vehicle composite driving system in which an internal combustion engine 1 is connected to a rotational electric machine 8 and an accessory 2 and motive power of the internal combustion engine 1 is transmitted to drive systems 5, 6, 7 via a clutch 3, when a fuel supply to the internal combustion engine 1 is stopped and an engine speed difference is generated in an input/output shaft of the clutch 3, the internal combustion engine 1 is driven by the rotational electric motor 8. Accordingly, even in the case of decelerating to a low speed in a furl supply stop state, the internal combustion engine 1 does not stopped, and the accessory function is secured because the accessory 2 is connected to the internal combustion engine 1.  Further, time necessary for cranking is not required because of rotation of the internal combustion engine 1, and once the fuel supply is restarted, the internal combustion engine 1 is driven immediately, whereby delay of the driving force at re-acceleration is avoided.

IPC: G03D3/08
Filed: 1993-06-17
Abstract: PURPOSE:To make it possible to insert photosensitive materials at specified intervals regardless of a change in transporting speed. CONSTITUTION:An LED is put out to announce that the insertion of the film is infeasible (step 154) when an insertion sensor detects the front end of the film (step 152). The number of the pulses outputted from an encoder connected to a driving shaft of a motor is counted and is successively subtracted from the prescribed value set according to the insertion intervals (length along the transporting path) of the film along the transporting path when the insertion sensor detects the rear end of the film (steps 158, 160). As a result, the step shifts to the steps 164, 166 to announce that the timing to permit the insertion of the fresh film is attained when the counter attains '0' as a result of the subtraction described above (step 162). The films are successively inserted at the specified transportation intervals regardless of the transporting speeds of the films by measuring the actual transporting quantity of the films in such a manner.

Title: Control method of disk drive device
Inventor: OTSUKA MASAFUMI
IPC: H02P23/03
Filed: 1991-05-22
Abstract: PURPOSE:To prevent a disk mounted on a tray from generating damage when the tray is sent out from the device body inside or is pulled in the device body inside. CONSTITUTION:When a front loading motor 4 to move the tray is driven, a gradually increasing voltage is generated with a integrating circuit 24 and the voltage is applied to the front loading motor 4 and at a movement start time of the tray, the rotation number of the front loading motor 4 is made small and the acceleration of the tray is made so as not to be more than a friction force between the disk and the tray. The applied voltage of the float loading disk motor 4 is made larger as the time passes and the applied voltage is finally made to a constant voltage. Thus at a movement start time of the tray, the disk does not move in the recess inside of the tray and the damage due to the friction does not generate on the disk.

IPC: G11B15/02
Filed: 1978-11-27
Abstract: PURPOSE: To improve reliability of detection operation by stopping a tape recorder automatically and electrically by detecting of rotation directions of two reel turntables and then by detecting those rotation directions differing.  
     CONSTITUTION: Left reel 2 and right reel 5 both turn counterclockwise in playback mode and clockwise in rewind mode. In operation, left reel 2 generates clockwise torque and right reel 5 also generates counterclockwise torque. Therefore, the completion of taking up a tape can be discriminated by detecting left and right reels 2 and 5 turning in opposite directions. Here, outputs of rotation-direction detecting circuits 10 and 12 of reel turntables 9 and 11 with left and right reels 2 and 3 loaded are inputted to comparing decision circuit 13 and when both outputs are found different, delay circuit 14 is supplied with its output. When the output of comparing decision circuit 13 is generated continuously for a certain time, delay circuit 14 generates its output to stop the tape recorder electrically through control circuit 15. In this way, the reliability of detection operation can be improved.

Title: Electric discharge machine
Inventor: KAWADA KOICHI
IPC: B23H7/32
Filed: 1985-07-04
Abstract: PURPOSE:To machine a work highly accurately with low thermal deformation while to protect the electrode from breakdown by providing a sensor for detecting the distance between the electrode and a work to control the feeding controller in said feeding controller for supporting the machining electrode. CONSTITUTION:The distance between the electrode 3 and a conductive film B is detected through a sensor 5 while servo mechanism 4 is driven through distance detecting circuit 7 to lower the electrode 3 and the sensor 5. Since the electrode 3 and the conductive film B are not charged, lowering of electrode 3 will cause electric discharge machining onto said film B and when machining has proceeded to remove the objective film B, the distance between the electrode 3 and the film B is detected through the sensor 5 to drive the servo mechanism 4 through distance detecting circuit 7 thus to lift the electrode 3 and the sensor 5. Consequently, thermal deformation will never occur even for a work as thin as 1mum to enable highly accurate pattern machining and trimming while to protect the electrode from breakdown.

Filed: 1991-05-23
Abstract: PURPOSE:To obtain a detergent which shows excellent detergency in cleaning a flux used for soldering electronic parts by mixing a specified fluorinated cyclic ether with a compound selected from specified groups of compounds. CONSTITUTION:97-50wt.% fluorinated cyclic ether of the formula is mixed with 3-50wt.% of at least one compound selected from alcohols, ketones, esters, and hydrogen chloride to give a flux cleaning agent. This flux cleaning agent shows performance comparable to that of 1,1,2-trichloro-1,2,2-trifluoroethane (F-113) detergent and also has little possibility of causing ozonosphere destruction. Therefore when the use of F-113 detergent is prohibited, it can be suitably utilized for cleaning a flux used in soldering electronic parts.
