Filed: 1993-02-12
Abstract: PURPOSE:To accurately follow up the position of a reading sensor to the center of an information track by wobbling the information track provided between adjacent synchronizing signals recorded at an equal time interval perpendicularly in the track longitudinal direction with the frequency of integer multiple of the synchronizing signal. CONSTITUTION:The information 41 of video and audio, etc., are arranged alternately with the synchronizing signal 40 arranged at an equal time interval in the information track (a). The information track is wobbled perpendicularly in whose longitudinal direction by a wobbling signals (b), (d) at the time of recording the information. The signals are synchronized to the synchronizing signal 40, and are sine waves having the frequency of N times of the synchronizing signal. Then, (b) indicates the case of N=1 and (d) indicates the case of N=2. (c), (e) show the reference wave of the same frequency and the same phase as the wobbling signals shown in (b), (d) respectively, and the pursuit of the reading senser to the center of the track is performed by synchronous- rectifying a regenerative output by the reference wave.

Title: Input and output variable device of static power converter
Inventor: OGINO YOSHIO
IPC: H02M7/44
Filed: 1978-03-01
Abstract: PURPOSE: To make output control over wide ranges possible, by combining frequency control and duty control.  
     CONSTITUTION: A means 26 is mounted which detects error voltage between an input and output set means 13 and an input and output detecting means 7 and prohibits the action of an inverter for a fixed first period by the detecting output. And a second prohibiting means 31 is installed which synchronizes with the starting and stop signals of the inverter and fixes the output of a frequency variable means 3 at a fixed limiter value for a fixed second period. Such an arrangement frequency controls this variable device when the set of the frequency variable means 3 is not less than the limiter value in response to the set, and duty controls the device with frequency at the limiter value.

Title: Base-stone block for slope frame
Inventor: KUSATAKE SUGIAKI
IPC: E02D17/20
Filed: 1982-02-16
Abstract: PURPOSE:To prevent the blocking with soil, sand, and dust of water-flow conduits by a method in which a water conveyance port leading to the water-flow paths formed in the inside cavities of slope frames laid at the lowermost portion of a slope is provided piercingly in the back of cylindrical blocks. CONSTITUTION:The water conveyance port 13' of a slope frame base-stone block 13 in which the upper half portion at the lowermost portion of a slope is of a  water-permeable layer and also the lower and both side portions are of a water- impermeable layer is connected with an infiltration box 16 butted with the lower openings of the water-flow conduits 15 of slope frames 14 provided on the slope and base-stone blocks 13 are joined. By this, surface water coming from the water-flow paths 15 once flows into the infiltration box 16 and then is discharged from the water conveyance port 13' to the water-flow conduits 4 of the slope frame base-stone block 13. Thus, since both the water-flow conduits 4 and 15 are of a culvert type, there is no fear of blocking with soil, sand, dust, empty cans, etc.

Filed: 1983-02-15
Abstract: PURPOSE:To enable to attain the exfoliation of the unnecessary part of a film between fine patterns by peeling an unnecessary film off as well at the same time by a method wherein a liquid state resin of the pack system is coated on a substrate and, after the resin is cured, the cured resin is stripped off. CONSTITUTION:After bumping and patterning are completed and, after that, a wafer is dipped into acetone. A photoresist, which has become unnecessary, is made to elute and the unnecessary part 41 of an evaporated film 4 is made in a floating state. A resin (silicon resin, etc.) 8 of the pack system in a liquid state is coated on the whole surface of the wafer. The coating of resin is performed by a brush-on method or a spray coating method, etc. After then, said resin is made to cure by a natural drying in a state that the resin has been made to tightly adhere to the unnecessary part 41 of the whole surface-evaporated film 4. By stripping the cured resin 8 off, the unnecessary part 41 of the whole surface evaporated film adhering tightly to the resin is also peeled off. According to these procedures, there exist almost no adverse influences to exercise up on an LSI. Accordingly, the generation rate of defects in the LSI can be also reduced remarkably.

Title: Screw extruder for viscous material
Inventor: SARUMARU KAZUMASA
IPC: B29C48/76
Filed: 1987-02-03
Abstract: PURPOSE:To heighten the removing rate of moisture, preventing the occurrence of vent clogging phenomenon by sucking gas content from a vent hole by way of a vacuum pump, while arranging a small screw transporting device for pushing back viscous material in the vent hole. CONSTITUTION:A small screw transporting device 6 for pushing back viscous material is arranged in a vent hole 5 so that its tip almost conforms to the inner peripheral surface of a casing 2. Viscous material thrown into the casing 2 from a throwing port 4 is transported downstream by a screw 3, but since the pitch of the screw 3 becomes smaller in the kneading range in the downstream side, the viscous material is pressurized and its temperature is raised. In the position of the vent hole 5, however, the pitch of the screw 3 is enlarged, and it is sucked by a vacuum pump from the vent hole 5, whereby the pressure in the casing 2 is reduced, therefore the moisture in the viscous material is gasified by evaporation and is emitted out. The viscous material sucked in the vent hole 5 is pushed back into the casing 2 by the screw transporting device 6.

Title: Pcm-pwm converter
Inventor: WACHI SHIGEAKI
IPC: H03M1/82
Filed: 1983-02-21
Abstract: PURPOSE:To correct the conversion distortion when a PWM signal formed by the 2nd converting circuit is converted into an analog signal by means of an addition/subtraction counter by providing the 1st and 2nd converting circuits, the addition/subtraction counter and a PWM modulator. CONSTITUTION:A reproduced analog signal is converted into the PWM signal by the PWM modulator 18 and the conversion distortion is corrected by feeding back this output signal PWM. Suppose that the output signal PWM3 is converted into the PWM signal having 60% of duty by the distortion caused by a pulse having, e.g., 50% duty, an output signal PWM1 outputted from the 1st converting circuit 11, when it is converted into an anaog signal through an amplifier 15 and an LPF16. Since the addition/subtraction counter 13 leaves the count value of -10%, an output signal PWM2 having 40% of duty is outputted from a comparison circuit 14b provided to the 2nd converting circuit 14 in the next sampling period, resulting that the output is corrected so as to generate an analog signal corresponding to a pulse having 50% of duty.

IPC: G03G5/047
Filed: 1990-02-06
Abstract: PURPOSE:To reduce deterioration of potential in the light and to enhance repeated use characteristics by incorporating a combination of 2 kinds of electric charge transfer materials specified in the difference between the melting points of both transfer material. CONSTITUTION:The electrophotographic sensitive body is formed by laminating on a conductive substrate 1 a charge generating layer 2, and the charge transfer layer 3 formed by using a coating fluid obtained by dispersing the organic charge transfer materials into a binder resin. The layer 3 serves as an insulating layer in the dark and maintains the charge of the photosensitive body and at the time of receiving light, it exhibits a function of transferring charge injected from the charge generating layer 2. As the charge transfer material, the 2 kinds of materials different from each other in melting points are selected from a group of the derivatives of pyrazoline, hydrazone, triphenylmethane, oxadiazole, and the like, thus permitting the obtained laminate type electrophotographic sensitive body to prevent deterioration of potential in the light at the time of repeated uses and deterioration of image quality.
