Title: Manual paper feed control system
Inventor: TAKAI TAKAHARU
IPC: B41J11/42
Filed: 1978-08-23
Abstract: PURPOSE: To perform the adjustment for the paper position in an easy and quick way by varying the discontinuation between spacing signals from the longer to shorter time gradually after starting.  
     CONSTITUTION: The paper feed driving control signal given from operation panel switch circuit 1 is transmitted to paper feed driving circuit 3 to control the pulse motor through manual paper feed control circuit 2 to carry out the manual control. Timer setting circuit 4 sets the timing so that the discontinuation between the spacing signals produced via the counter and the timer may be varied from the longer to shorter interval after starting. As a result, the paper position can be adjusted in an easy and quick way.

Title: Magnetic tape recording and reproducing device
Inventor: KIME KENJIRO
IPC: G11B5/588
Filed: 1990-04-18
Abstract: PURPOSE:To use a single magnetic head for recording and reproducing and to attain the cost reduction by providing an optical sensor which detects the position of a movable magnetic head against a fixed magnetic head. CONSTITUTION:The positions for the recording/reproducing magnetic heads 57a and 57b are detected by an optical sensor 1, and the positional deviations of both heads 57a and 57b are corrected against a reference position based on the detected positions of both heads 57a and 57b. Thus a single magnetic head can be used for recording and reproducing, therefore the number of magnetic heads to be attached can be reduced. Then the accuracy is relaxed at adjustment and a positional deviation caused by a secular change can also be corrected.

IPC: G12B11/00
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To effectively guide the light of a substantially linear light emitting element into a photoconducting plate, without increasing the thickness of the plate. SOLUTION: V-shaped grooves 331 to 333, 341 to 343 are formed on the rear surface 3b of a photoconducting plate 3, and oblique surfaces 31, 32 are formed on the front surface of the plate 3.

Filed: 1983-06-10
Abstract: PURPOSE:To enable to operate a semiconductor device at a high speed by forming a channel of an MOSFET of single crystal, and respectively forming source and drain regions of a single crystal Si grain powder and polycrystalline Si. CONSTITUTION:After a polycrystalline Si thin film 2 is formed on an insulating substrate 1, parts 2' of a channel region 3 and source, drain are formed in single crystal. At this time, a single crystal Si grain powder is produced in the boundary between the regions 2' and 2. After a gate region 6 and a gate electrode 7 are then formed, source and drain diffused layers are formed, and a thin metal film 5 is accumulated on the surface of the source and drain diffused layers. Since the region 3 of the MOSFET having this structure is formed of single crystal Si, the mobility of conduction electrons or holes is high, and a high speed operation can be performed. Further, since the metal layer of the surface layer of the source and drain regions are formed of ohmic contact with Si, the resistances of the source and the drain exhibit stable low resistances.

Title: Positioning method for magnetic head
Inventor: OKADA MINORU
IPC: G11B21/08
Filed: 1978-08-28
Abstract: PURPOSE: To make a method tolerant of an overshoot even if seek time is short by using odd and even tracks and a saw-tooth wave as a position signal.  
     CONSTITUTION: The phase variation of a signal from position detector 6 is made identical at every four tracks and a saw-tooth wave of every two tracks can be formed by making a comparison between the phase of signal (a) from oscillator 9 and that of signal (b) from rectangular-wave converter 8. Now, when a head moves toward a traget track after the start of seek operation, position control starts from the halfway point between the target track and the track right before, but when the position control starts, either saw-tooth wave is used, as it is, as the position signal. Consequently, the linear part of the saw-tooth wave is equivalent to ± tracks in case of the position control, therefore, even if the seek time is shortened, it becomes tolerant of an overshoot.
