Title: Magnetic recording medium
Inventor: KAI YOSHIAKI
IPC: G11B5/725
Filed: 1989-10-17
Abstract: PURPOSE:To improve durable reliability by forming lubricant layers consisting of a partially fluorinated alkyl system via protective layers consisting of a carbon system on ferromagnetic metallic thin films. CONSTITUTION:The lubricant layers consisting of the partially fluorinated alkyl system are formed via the protective layers consisting of the carbon system on the ferromagnetic metallic thin films. For example, the ferromagnetic metallic thin films 2, 2 are provided on both surfaces of a nonmagnetic base 1 and further, the lubricating layers 4, 4 are provided via the protective layers 3, 3 consisting of the carbon system on both surfaces of the ferromagnetic metallic thin films 2, 2. The good durable reliability is obtd. in this way without degrading the performance, such as CSS durability and head attraction, even if the surface flatness is fairly improved by decreasing the projection height of the surface for the purpose of improving the recording density.

Title: Method and device that control electric current profile in srm
Inventor: GEERII EDOWAADO HOOSUTO
IPC: H02P27/08
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce noise of SRM by outputting a PWM signal to at least one of two switches in response to an input from a PWM signal generator or a microprocessor thereby controlling the current to winding. SOLUTION: A circuit 10 comprises a PWM signal generator 16 for providing an operation signal to one or both of switches S1, S2 and both the PWM signal generator 16 or a microprocessor generates a PWM signal of 'soft' chopping signal or 'hard' chopping signal. When the current profile is controlled at the energizing part of each phase so that the noise of a motor is reduced, the current level is increased at first to a peak level higher than a normal level and then it is lowered to the normal level when the phase is deenergized. Since the inclination of current profile becomes gentler when the phase is deenergized as compared with other case, noise of SRM can be lowered.

Title: Voice recording device
Inventor: SAKAKIBARA MANABU
IPC: G11B20/02
Filed: 1988-10-27
Abstract: PURPOSE:To specify the various kinds of input modes with the aid of few input means, to suppress an operation part to be large size and to simplify an operation procedure by providing plural recording modes and executing the selection of the respective recording modes with the aid of using a track number input means. CONSTITUTION:A control code is added to an inputted voice signal by an addi tion circuit 14 and an FM voice signal corresponding to the code is recorded on a disk 28. The selection of the post-recording mode is executed by inputting a corresponding video track number with the aid of ten keys 34 and depressing a start key 36, next. Thus, the inputted voice signal is recorded as a voice corresponding to a video and the track number which are previously recorded. The selection of the A mode is executed by inputting a number except 1-50, for example zero, as the track number and depressing the key 36, next. The selection of the pre-recording mode is executed by depressing the key 36 without inputting the track number. Since the video is recorded after the voice in this mode, an unrecorded track is secured for the video when the voice is recorded and the track number thereof is included in a control signal as the video track number.

Abstract: PURPOSE:To obtain a low cost device having high heat radiating characteristics corresponding to high temperature heating, by bonding a semiconductor chip to the recessed inner bottom of a bed part, and exposing the recessed bottom part to the surface of molding resin, without using a heat sink. CONSTITUTION:A bed-part forming place in a thin metal plate is contracted in a recess state. The place is shaped so as to form a bed part 2. Blanking is performed so as to form bed-part supporting pieces 3, leads 4, linking parts 6 and the like. Thus a leadframe having a specified shape is formed. At this time, the shape of a part of the bed part is formed in a recessed shape so that the peripheral part of the opening of the recessed part becomes a flat flare shape. Thereafter, a doughnut shaped insulating material 9 such as polyimide is attached to the flare part by a bonding agent. Then, a semiconductor chip 1 is mounted on the inner bottom of the recessed part of the bed part by soldering or other methods. Thin wires made of gold and the like are bonded. Thereafter, the bottom surface of the bed part is exposed to the outer surface of the molding resin. Thus the semiconductor device is completed.

Title: Thin film transistor
Inventor: KOBAYASHI KEIZO
IPC: H01L29/78
Filed: 1992-10-08
Abstract: PURPOSE:To suppress the back channel leakage current affected by the positive charge in a passivation film in the thin film transistor using an amorphous silicon. CONSTITUTION:The thin film transistor ia an inverse stagger type TFT wherein a P type doped amorphous silicon layer 19 is provided on the interface between a passivation film 18 and an island layer 13. At this time, the carrier electron density is low in the P type amorphous silicon layer 19. Thus, the electron density induced by the positive charge on the interface between the passivation film 18 and the P type amorphous silicon layer 19 is also lowered not to lower the resistance so much in this part. Accordingly, the leakage current flowing in such a part can be suppressed.

Title: Twistless plastic tape and its manufacture
Inventor: ABE MITSUHIKO
IPC: B29C48/305
Filed: 1990-10-08
Abstract: PURPOSE:To constitute the title method so that even if the title plastic tape is wound round a winding drum, it is not twisted at the time of pulling out of the same, by making the title tape into a form where a sectional form of a widthwise direction or the central part are made respectively into an arc or a thin thickness. CONSTITUTION:Since molten plastic is introduced into a hole 3a, whose section becomes an arc or the central part is narrowed, of a die 3, a plastic tape where it is formed so that a sectional form of a widthwise direction or the central part are made respectively into the arc or a thin thickness is manufactured. In other words, since a heating roll 7 rotating along a moving direction of a plastic tape 6 is contacted to one side of the moving tape in the title method, with this construction, the surface of the plastic tape 6 with which the heating roll 7 is contacted is warped by thermal shrinkage and the plastic tape whose sectional form in the widthwise direction is in the arc is manufactured. A part pulled out becomes straight even at the time when the same is pulled out from a state where it is wound up in this plastic tape.
