Title: Transistor and its manufacture
Inventor: OONO NORIO
IPC: H01L21/331
Filed: 1978-06-14
Abstract: PURPOSE: To secure the uniform operation for the emitter-base junction within a limited area by providing the high-impurity density region to at least one of the comb-line base and emitter regions.  
     CONSTITUTION: P + -base region 3 is formed on N - -collector layer 2 formed on N + -Si substrate 1, and emitter region 4 is formed selectively in region 3 into the comb-line form. Then N +  high-density region of the same conducting type as the emitter is formed selectively at part of the emitter region 4. At the same time, regions i and j are formed. Thus, the current flowing to the emitter electrode from the emitter-base junction becomes large enouth at the tip of the comb-line region in comparison with the uniform emitter structure, and increasing greatly the active area of the transistor per comb's line. The same application can be given not only to region 4 but to region 3. As a result, the uniform operation is ensured within a limited area for the emitter-base junction.

IPC: H02P21/34
Filed: 1988-03-25
Abstract: PURPOSE:To enable speed change up to high speed rotation by employing a plurality of low resistance conductors in a plurality of rotor cores. CONSTITUTION:A plurality of conductors 5 arranged in rotor cores 2, 3 mounted on a rotor shaft with a random interval are connected in series thus forming a rotor 8. Respective conductors 5 are shortcircuited through resistive members (r) at a non-magnetic core section 9 between the rotor cores 2, 3. Stators 24, 25 are juxtaposed to a machine frame 14 on the outer circumferential section facing with the rotor cores 2, 3. Torque of motor is controlled by regulating the phase difference between the stator 25 and a fixed stator 24 through a voltage phase shifter 38. The conductors 5 have low resistance. By such arrangement, wide range speed change can be made for a load having constant torque characteristic.

Title: Surface acoustic wave filter
Inventor: MATSUI KUNIYUKI
IPC: H03H9/64
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To maintain a satisfactory filter characteristic even if pass band width is wide by setting the number of the gratings of grating reflectors in parallel arm resonators to be less than a specified number or avoiding the installation of the grating reflectors. SOLUTION: The filter having this form does not have the grating reflector in the parallel arm resonators. The pass characteristics of the series arm resonators 5 and the parallel arm resonators 6 in the filter do not change but ripples disappear in the parallel arm resonators 6. The ripples are removed and the pass characteristic of the filter in the form becomes the satisfactory one satisfying a requested spec. When the number of the gratings in the grating reflectors in the parallel arm resonators 6 is less than thirty, the sizes of the ripples reduce as the number of the gratings is reduced.

Abstract: PURPOSE:To retrieve the load received by the link device itself of the sprocket part on an outlet side, by providing an intermediate drive device, which pulls the link device of a stretched part and sends the same into a longitudinally shrinking section after stretching, to the outlet part of the stretched part. CONSTITUTION:A non-stretched flat film 1 is grasped at both side edge parts thereof by the grasping devices 5 provided to endless link devices 4 driven by inlet sprockets 2, 2' and outlet sprockets 3, 3' but, since the link devices of a stretched part A and a longitudinally shrinking section B after stretching are run in a shrunk state, excessive drive load is generated by wedge effect. By driving a chain 6 equipped with top rollers fitted to a link pitch by a drive sprocket 8, the link devices of the stretched part are driven. Therefore, only the drive load due to the wedge effect of the link device of the longitudinally shrinking section after stetching acts on the outlet sprockets 3, 3' and the drive load can be suppressed. The load to the link devices and the outlet drive devices can be retrieved small.
