IPC: H04W74/08
Filed: 1988-10-27
Abstract: PURPOSE:To prevent communication efficiency and power efficiency from being lowered by making a communication system including the communication terminal of a data system into a radio system when a time in which voice information is transmitted like a telephone set, etc., forms part of entire communication time. CONSTITUTION:A various kinds of radio communication terminals 2 such as the telephone set, FAX, and a data terminal, etc., are provided for a base station 1, and when a nonaudio state is generated in communication by the telephone set, the transmission of an instantaneous packet is stopped, and when a null slot is generated, the communication by an uninstantaneous packet such as the FAX, the data terminal, etc., is performed by using the null slot, thereby, superior communication efficiency can be obtained, and also, the transmission of the instantaneous packet is stopped when the nonaudio state is generated in the communication of the telephone set, which improves the power efficiency that is a problem when the communication system is made into the radio system. Furthermore, since the communication is performed by adding a dummy packet at the time of starting the communication of the telephone set, sound quality can be guaranteed.

IPC: F16F1/10
Filed: 1987-10-29
Abstract: PURPOSE:To reduce friction between plates and make no disorder of torque by forming the spring in the caption to have a radius of curvature to be gradually increased from the inner periphery, at least, to the middle of lap winding in the primary winding work, in order that the corresponding peripheral surface portions do not come into close contact with each other in the winding condition of the secondary winding. CONSTITUTION:A control apparatus 30 is controlled on the basis of the detected signal from a detecting member 28 in order that a die 20 moves in the direction of an arrow (O) wherein the space (G) increases gradually in accordance with the feed length of a material 13. As a result, a spiral spring 15 having a radius of curvature which increases gradually as it goes from the inner periphery to the outer periphery following the movement of the die 20 can be worked. A heat treatment after the primary winding work and secondary winding work are the same as those of a conventional method, thus, an S-shaped spiral spring 15 can be obtained. In this spiral spring 15, since its related peripheral portions do not come into close contact with each other, the friction between plates is small, so that the S-shaped spiral spring 15 with no torque disorder can be obtained.

Title: Reproduction system of video signal
Inventor: UEDA MAMORU
IPC: H04N5/783
Filed: 1984-12-24
Abstract: PURPOSE:To decrease both the maximum deviation of a rotary magnetic head for reproduction and the overlap amount of a tape winding angle around a tape guide drum, by shifting a magnetic head in the direction approximately orthogonal to a sloping track and scanning plural sloping tracks in the order opposite to a recording mode for reproduction of recording signals. CONSTITUTION:In a figure 1 the areas enclosed by the broken lines show the sloping tracks where the digital signals are recorded. The figures A-D show four tracks which forms a sheet of field to be reproduced in the order of A-D. Here a DT head is moved for scanning in the order of 1-4 and four tracks are reproduced, that is, the tracks D, C, B and A are reproduced in the loci 1, 2, 3 and 4 respectively. Thus the video signals equivalent to a field are obtained. In this case, the maximum deflection width HDT of the DT head is set as shown in a figure 2 for each reproduction speed (including still and forward reproductions) as well as reverse reproduction) VT. In other words, the width HDH is reduced to the same speed VT in comparison with conventional values in case the reverse reproduction speed VT is less than 0.

Filed: 1990-10-12
Abstract: PURPOSE:To suppress the generation of hot carriers in the end part of a drain by a method wherein a wiring-shaped first conductive film, a wiring shaped second conductive film and third conductive films left on both sides of this second conductive film are arranged in such a way that the width of the first conductive film coincides almost with the sum of the width of the second conduc tive film and the widths of the third conductive films. CONSTITUTION:The arrangement of a wiring-shaped polysilicon first conductive film 120A, a wiring-shaped polysilicon second conductive film 150A and polysilicon third conductive films 158A and 158B left on both sides of the film 150A is specified in such a way that the width of the film 120A coincides almost with the sum of the width of the film 150A and the widths of the films 158A and 158B. In this MOS transistor, an n-type semiconductor region 200D at the end part of a drain overlaps sufficiently with the polysilicon pattern 120A for gate electrode use. Accordingly, an electric field applied to the end part of the drain is small compared to that applied to a MOS element formed by a normal method. Thereby, the generation of hot carriers in the end part of the drain is suppressed and an element having a superior reliability is obtained.

Title: Ferromagnetic metal powder coated with alkylphenol and manufacture thereof
Inventor: OSHIMA KAZUFUMI
IPC: C09D161/08
Filed: 1984-12-27
Abstract: PURPOSE:To obtain the ferromagnetic metal powder applied to audio-appliances and VTRs which consists of iron mainly and has the exceedingly improved characteristics by using Fe including at least B coated with alkylphenol as a main component. CONSTITUTION:The ferromagnetic metal powder fine particles mainly consisting iron for this use are manufactured by coating a surface part of the fine particle of needle iron axyhydroxide with zinc borate as a shape retentive component and subjecting the particles to cleaning, drying, and milling followed by calcination and gas-phase catalytic reduction. The reduce iron powder fine particles preferably include B as the shape retentive component at least within a range of 0.1-5 atomic weight percent age to Fe. If the percentage is under the above range, the performance of forming a non-eliminable coating layer of alkylphenol group is low and the effect that the characteristic of deterioration with aging of the ferromagnetic metal powder fine particles is improved is diminished. If the percentage is over the range, the formation of the non-eliminable coating layer of alkylphenol group progresses too intensively so that the dispersion property during a step of conversion into coating compositions is lowered though affinity for a binder resin is improved.

Title: Semiconductor light sensitive element
Inventor: TSUJI MASAYOSHI
IPC: H01L31/10
Filed: 1994-11-08
Abstract: PURPOSE: To obtain a PIN-PD with a large light receiving diameter, high quantum efficiency and wide band by including two or more p-n junctions in the structure of a semiconductor light sensitive element, and using GaAs sensitive to light of specific bands to from the element's light absorption layer. CONSTITUTION: A n<+> -type GaAs buffer layer 2, a n<-> -type GaAs light absorption layer 3, a n<-> -type AlGaAs piling-up preventive layer 6, an n-type AlGaInP window layer 3, a p<+> -type light receiving region 7 and a SiNx film are formed on a p-type GaAs substrate 4, and the p-side electrode 10 of the substrate 10 is also formed. The GaAs light absorption layer 3 is so formed that it will be sensitive to 0.6μmband light. Since the widely gapped n-type AlGaInP window layer 5 is placed on the surface side, therefore, 0.6μm light will be absorbed not into the n-type AlGaInP window layer 5 but only into the GaAs light absorption layer 3. Thus photo carriers do not absorb light in the neutral region, which improves external quantum efficiency.
