IPC: H04B7/005
Filed: 1979-09-14
Abstract: PURPOSE:To make it possible to avoid a dead point due to multipath by setting a local oscillation frequency to (f1+f2)/2 (f1 and f2 are carrier frequencies) and by providing an intermediate frequency amplifier that has its intermediate frequency set to (f1-f2)/2. CONSTITUTION:In receiver B, received signals from receiving antennas 21 and 22 are inputted to high frequency amplifying circuit 4, but circuit 4 includes filters F1 and F2 that have their peaks of passing bands at carrier frequencies f1 and f2 and the received signals of frequencies f1 and f2 are amplified and applied to mixing circuit 6 at the following stage. Next, since local oscillating circuit 5 is so set that it will oscillate at frequency (f1+f2)/2, intermediate frequencies obtained by circuit 6, when the received signals of f1 and f2 are inputted, are considered to be (f1-f2)/2 and -[(f1-f2)/2] by calculation and in any case, an intermediate frequency output of (f1-f2)/2 is supposed to be obtained by circuit 6. Thus, the reception output that corresponds to frequency f1 or f2 is to be obtained, so that the communication can be prevented from being disabled due to a dead point.

Abstract: PURPOSE:To maintain the load applied on a driving motor approx. constant by varying the braking force of a donor feeding roll or the torque to a donor winding roll according to the changes in the diameter thereof being detected. CONSTITUTION:As soon as the delivery of a recording paper 7 starts with a start button pressed ON, the load adjustment of a driving motor 8 is started. A variable resistor 26 detects change in the diameter of a feed roll 2 which is inputted into a load signal generator 32 after an analog-digital conversion. From an address corresponding to the inputs, load signals are read out corresponding to the load to be corrected and inputted into an electromagnetic brake driving circuit 34 after a digital-analog conversion to set a current value for an electromagnetic brake 27 so that the load of the driving motor 8 can be maintained  at a fixed value. Otherwise, the load can be controlled with a clutch on the side  of a winding roll 6. This permits the correction of changes in the load only  depending on changes in the diameter of an arbitrary roll thereby simplifying the equipment and reducing the size thereof.

Title: Semiconductor device
Inventor: RIYOUNO KENICHIROU
IPC: H01L21/331
Filed: 1981-07-29
Abstract: PURPOSE:To improve the surge-resistant strength of a normal planar type PN junction without damaging the degree of integration by forming one part of a current path between the opposite two electrode windows of the junction into a low-concentration impurity layer forming the junction. CONSTITUTION:A V-shaped groove is shaped from the surface of the low-concentration epitaxial layer 2 forming the PN junction in a region held by electrodes 6, 7, and coated with an SiO2 film 4d. An interface 8 between the SiO2 film 4d and an Si crystal shapes the effective distance of 1.5-2 times as long as the case when there is no V-shaped groove. Accordingly, the surge resistant strength is improved without increasing an occupied area. When surge having polarity reverse-biasing the PN junction is applied transiently, the V-shaped groove or the semicolumnar insulating layer of SiO2 may be formed to the low concentration layer because the greater part is applied to the low-concentration layer side. According to this constitution, the surge resistant strength can be improved without increasing the occupied area.

Title: Reverse conducting thyristor
Inventor: HAGINO HIROYASU
IPC: H01L29/861
Filed: 1977-10-03
Abstract: PURPOSE:To improve break-over characteristics of a SCR part by forming the reverse conducting SCR, by constituting a reverse parallel diode especially inside it. CONSTITUTION:The p-type layer 17 occupies one part of one main surface and the 2nd n-type layer 18 occupies the remaining part and is exposed to the main surface. On the other surface, n-type layer 20 occupies partially the opposite part to layer 17 and on the remaining part, the 3rd p-type layer 19 is exposed. On the other hand, the SCR region in the pnpn structure covers the reverse conducting diode in the (pn) structure of layers 19 and 18. In this constitution, a current flowing into the negative resistance region of the SCR part is small and, equivalently, a break- over current becomes small, so that the power consumption of the circuit employing this element can be reduced. In addition, an element uniform in VBO is recommended for a gas ignition device, etc.

Title: Multi intake passage type 4-cycle engine
Inventor: SUGIYAMA KEIICHI
IPC: F02P5/145
Filed: 1982-07-09
Abstract: PURPOSE:To prevent drop of the torque during high load operation by allowing the suction passage leading to the combustion chamber to diverge in two intake passages and by opening a throttle valve in one of these passages when the engine operates with high load as well as advancing the ignition timing. CONSTITUTION:When No.1 throttle valve 11 is opened to a large extent to shift into high load operation, the amount of rotation of an air flow meter 12 will increase, and selector valves 20, 35 are switched over by a computer 16. Thereby No.2 intake passage 6 is opened to increase the area of passage, and a passage 34 leading to the main angle advance device 27 is put in communication with a neg. pressure accumulating chamber 22 through a passage 37. Accordingly a high pressure is applied to the main chamber 33 of the main angle advance device 27, and an actuating element 28 is drawn in the direction of Arrow A to work the distributor 25 onto the ignition timing advancing side. Thus temporary torque drop likely when the intake passage is opened and closed during high load operation can be prevented to ensure that always a high torque is maintained.

Abstract: PURPOSE:To improve an unwinding property by properly selecting the combination of the winding direction and the winding type of the parchment paper of a paper tube bobbin and the unwinding direction of yarn at the time of winding up the synthetic fiber yarn onto the paper tube bobbin. CONSTITUTION:A paper tube bobbin for winding up undrawn yarn into a package is formed with a three-layer structure consisting of a paper tube body, a sheet of wrapping paper on its surface, and a sheet of parchment paper 1 which is spirally wound further on the outside surface, and the winding direction of the parchment paper 1 is divided into a Z direction and an S direction. As for the winding type of the parchment paper 1, there are an upper-paper type in which the unwinding side on the opposite side to a yarn cutting groove 2 and a punch-winding forming part 3 becomes an upper paper side 4 and a lower paper type in which the unwinding side becomes a lower paper side 5. In this case, when winding-up is carried out by selecting the winding direction (Z), the winding type of upper-paper type, and a counterclockwise unwinding direction, or by selecting the winding direction (S), the upper-paper type, and a clockwise unwinding direction, yarn property unevenness, single yarn breakage, fluff, yarn breakage, etc., caused by variation in the tensile force of unwinding are not produced at the time of unwinding yarn. Hence, the machining speed can be increased, improving productivity.

Abstract: PURPOSE: To provide the titled system for use in the internal combustion engine, which is capable of warning troubles in its lubricating oil correctly and automatically under any operational conditions of the engine.  
     CONSTITUTION: A voltage signal proportional to the engine speed, obtained a speed sensor 1, is afforded to a reference value setting circuit 3, which produces a hydraulic reference signal VL corresponding to the engine speed. On the other hand, a voltage signal proportional to the hydraulic pressure, obtained by a hydraulic-pressure  sensor 2, is affored to an amplifying circuit 4, which produces a voltage signal VP. These two signals are supplied to a comparison circuit 6 for making comparison between them. Here, if the hydraulic output signal VP is lower than the reference voltage VL, a comparison signal of a predetermined voltage is produced. However, if the result of comparison is contrary, voltage of the comparison signal is rendered zero. In response to the comparison signal produced by the comparison circuit 6, current is supplied from a power source 9 to a warning means 8 by a driving circuit 7 for giving an alarm against the drop of hydraulic pressure.
