Title: Optical recording medium
Inventor: OGAWA YOSHIHIRO
IPC: G11B7/24073
Filed: 1989-02-01
Abstract: PURPOSE:To additionally stabilize a servo signal and to decrease the error rate at the time of information recording and reproducing by forming the sectional shape of the projecting parts of preformats to a triangular or trapezoidal shape when the preformat surface of a substrate is faced upward. CONSTITUTION:The sectional shape of the projecting parts 4 for tracking is formed to the triangular shape or the trapezoidal shape with which the length of top base b is <=1/10 the spat diameter of irradiation light so that the quantity of reflected light from the projecting parts 4 is sufficiently small compared with that of the recess parts 3. In this case, recording layers are hardly formed in the vertex (top bottom b) parts of the projecting parts or even if the recording layers are formed, the quantity of the reflected light from the projecting parts 4 is hardly detected as the length of (b) is smaller than the spot diameter of the irradiation light. The recording layers are formed along hypotenuses 7 of the projecting parts but the reflected light therein receives the diffraction effect of the hypotenuses, by which the quantity of the reflected light detected by the optical head is sufficiently decreased. As a result, the contrast ratio of the track crossing signal is improved. The identification and detection of the projecting parts which are the track regions are facilitated in this way and the off-tracking of a laser beam for recording and reproducing is decreased.

Abstract: PURPOSE:To prevent deterioration of the magnetic characteristics by the method wherein an iron core made of amorphous magnetic alloy thin film is provided with the electrodes on its surface which make the electric current flowing in said iron core uniform thereby applying the voltage between the electrodes to conduct the current to the whole iron core and annealing is performed by the heat generation of the iron core itself. CONSTITUTION:The iron core 1 consists of amorphous magnetic alloy thin film and is provided with the laterally elongated electrode plates 6 consisting of metallic material which are present on the peripheral surface and inner circumferential surface of the iron core respectively with face to each other. This iron core carrying the electrode plates 6 is inserted into a treatment oven 2 which is filled with gas such as nitrogen or argon and the voltage is applied between the electrodes 6 from a power source circuit 4 to flow predetermined current to the whole core 1 uniformly. Consequently, the temperature of the iron core 1 itself becomes the temperature sufficient for annealing by Joule heat. The circuit 4 flows the current to a heater in the treatment oven 2 thereby preventing decrease of annealing temperature of the iron core 1. Then the whole iron core 1 is heated till its temperature reaches the range of annealing temperature thereby it can be annealed whereas deterioration of the magnetic characteristics of the alloy thin film is prevented.

Title: Paper feeding of printer
Inventor: FUKUOKA HIROAKI
IPC: B41J11/42
Filed: 1981-02-23
Abstract: PURPOSE:To ensure the normal printing pitch at the start of printing by starting the printing when a pulse motor reaches the position of starting the reverse rotation thereof in the normal rotation following a reversal. CONSTITUTION:At the start of printing, the printing is started when a pulse motor 1 reaches the position of starting the reverse rotation in the normal rotation after making a slight reversal. When the motor shifts from the reverse to normal rotation, the pitch varies with the shifting in the tension from the position of the side B> the side A to the side A> the side B. As the printing is not yet started, this makes no difference. At the position of starting the reverse rotation, where the printing is actually started, a paper is fed under the tension of the side A> the side B thereby ensuring the normal printing pitch.

Filed: 1979-03-06
Abstract: PURPOSE:To improve the reliability of an IC by increasing the depth of the junction of an input protective element larger than that of a diffused layer, thereby preventing the breakdown withstand voltage thereof from lowering. CONSTITUTION:A diffused layer 14 of an input protective element has a deeper junction depth than the diffused layers of source and drain 16, 16' of an internal element. The channel stopper 17 making contact with the diffused layer 14 of the input protective element is deeper than the channel stopper 19 making contact with the diffused layers 16, 16'. Thus, the internal element prevents a short channel effect to enhance its performance. Accordingly, shallower diffused layer may be formed. Since the input protective element employs deeper diffused layer, it can improve the reliability of the IC against the input breakdown.
