Title: Direction control system for low-speed traveling object
Inventor: KATAGAI TAKESHI
IPC: G01C21/04
Filed: 1989-01-11
Abstract: PURPOSE:To control the direction of a traveling object in real time even with a radio circuit that does not have so much high quality of transmission by correcting the change of a target azimuth caused by the advance of a traveling object at the side of the traveling object in a remote control system for traveling object which is carried out with transmission of the radio data. CONSTITUTION:At the side of a fixed station controller 1, an entire traveling area of a traveling object is divided into meshes and all target azimuths showing the traveling directions of a traveling object are calculated in the form of a table. A coordinate conversion part 4 converts the position information on the object 15 detected by a position detecting part 9 into the XY coordinates to produce the coordinate data. A control part 3 sends the correcting value of the target azimuth obtained when the object 15 shifts by a unit time to a traveling object controller 10 together with the target azimuth. Thus transmitting radio wave is demodulated by a radio MODEM 14 of the controller 10, and a control part 11 corrects the target azimuth for each unit time based on the correction value received together with the present target azimuth before input of the next target azimuth. Thus it is possible to control the object 15 in real time even with a radio circuit that does not have so much high quality of transmission.

Title: Bridge type converter circuit
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/5387
Filed: 1990-01-16
Abstract: PURPOSE:To obtain a small and highly efficient inverter circuit by employing an MCT(Mos Controlled Thyristor) in a DC positive side bridge and an IGBT (Insulated Gate Bipolor Transistor) in a DC negative side bridge in an inverter bridge. CONSTITUTION:MCTs 51, 53, 55 are connected to the positive side DC bus while IGBTs 42, 44, 46 are connected to the negative side DC bus of an inverter bridge 4. Consequently, the MCT and the IGBT require only one power supply respectively. Since the MCT has low loss characteristic, operation efficiency is improved. When load terminals are short-circuited, a current flows from a DC power supply through the MCT and the IGBT. The fault current is limited through the transistor function of the IGBT, and when an overcurrent is detected and the MCT and the IGBT are quickly turned OFF, the current can be interrupted at a value smaller than the maximum interruption current of the MCT.

Title: Image pickup tube target
Inventor: ISHIOKA YOSHIO
IPC: H01J29/45
Filed: 1987-01-14
Abstract: PURPOSE:To obtain the low afterimage and high resolution and improve sensitivity by applying the electric field multiplying charges in a semiconductor layer to a photoconductive target having a blocking type structure and operating it at the preset temperature or below. CONSTITUTION:The electric field is applied to a pickup tube target having a translucent substrate 1, a transparent conductive film 2, an amorphous Se photoconductive layer 4, and an electron injection blocking layer 5 as basic portions with a preset signal current. Under this condition, when the light is radiated from the glass substrate side, most of the incident light is absorbed mainly by the transparent electrode side of the amorphous Se layer to generate a pair of electrons and positive holes. Among them, electrons run to the transparent electrode side, and posive holes run to the electron injection blocking layer through the amorphous Se layer. Therefore, a charge multiplying action occurs when the positive holes run through the amorphous Se layer in the high electric field, if the amorphous is made thick enough to get the desired characteristic, electric charges are multiplied, and high sensitivity having a gain larger than 1 can be obtained, with the low-afterimage property of a blocking type target maintained. Furthermore, if the temperature of the target is made 40 deg.C or below, highlight burning is quickly eliminated, and a good image can be obtained.

Title: Television receiver
Inventor: ISHITANI SHIZUO
IPC: H04N5/44
Filed: 1979-01-13
Abstract: PURPOSE: To prevent the generation of a buzz and the mixture of noise disturbance by shifting a resonance point according to an input level by feeding a sound intermediate-frequency signal back to a sound trap by detecting its amplitude level.  
     CONSTITUTION: A sound intermediate-frequency signal after passing through sound intermediate-frequency detector 5 and sound intermediate-frequency tuning filter 6 is biased 6 and 7 through amplifier circuits 12∼14, and capacitor 15, peak-detected by detection circuits 18∼20, and then converted into a DC voltage, which is applied to varactor diode 11 by way of filter circuits 21∼23. Diode 11 decreases in its capacity C 3  when the applied backward voltage is large and increases in capacity C 3  when small. When a sound input with the resonance point of a sound trap at f 0 ' is small, a signal at point (a) is small, a DC component at point (c) is also small, and the backward voltage of diode 11 is low, increasing capacity C 3 . The resonance point is therefore shifted from f 0 ' to f 0 ", and consequently the attenuation value of a local signal is lessened to increase the sound signal, so that no disturbance of a buzz will be caused. Even in a weak electric field, the resonance point of the trap is shifted to the lower side.
