Title: Vhf television antenna
Inventor: SHIROSAKA TOSHIAKI
IPC: H01Q19/30
Filed: 1990-03-28
Abstract: PURPOSE:To improve the front-to-back ratio of the antenna at a VHF low channel and to realize a VHF television antenna at a low cost with a light weight by arranging a low-channel composite director adjacently to VHF high channel directions onto an arm. CONSTITUTION:The antenna is provided with plural VHF high channel directors 6 arranged on an arm 4 at a prescribed interval and with a VHF low channel director 22 between the VHF high channel directors arranged side by side on the arm. The VHF low channel director 22 consists of two composite directors with an inductor provided therein and arranged side by side closely. That is, since the VHF low channel director 22 is arranged on the arm, a vertical arm or the like to support the VHF low channel director 22 is not required, and the front-to-back ratio of the antenna at the VHF low channel is improved by selecting the inductance of the composite directors to be nearly 370nH and the interval between the composite directors to be nearly 50mm. Thus, the VHF television antenna is realized at a low cost with a light weight.

Title: Driving device
Inventor: TOTANI HIROSHI
IPC: H04N1/032
Filed: 1985-04-19
Abstract: PURPOSE:To improve the driving performance of a driving device to the load with small power consumption and a small packing area, by forming a signal processing circuit including a shift register, etc. on a semiconductor substrate with use of a CMOS that can work with low power consumption. CONSTITUTION:A shift transistor is formed on a semiconductor substrate with a CMOS together with an output circuit containing a bipolar transistor TR. Furthermore, input signal supply terminals are collected on a single side face of a semiconductor chip. While output terminals, power supply terminals for output circuits, GND terminals, etc. are provided successively on other three side faces of the chip respectively. Thus shift registers FF1-FF64, AND gates A1-A64 and a selection circuit 100 are used to form a control circuit together with the CMOS. Therefore, the power consumption can be reduced with this control circuit. An output circuit consists of buffer amplifiers B1-B64 and TR Q1-Q64 together with a bipolar TR. Thus the driving performance of a driving device is improved although the output circuit occupies a small area against the semiconductor chip.

Title: Direct-acting servo valve
Inventor: ICHIYANAGI TAKESHI
IPC: F15B13/044
Filed: 1979-07-02
Abstract: PURPOSE: To improve responsibility and damping characteristics of servo valve, by reducing frictional force acted between spool and sleeve to a great extent and thereby ensuring smooth movement of the spool in the sleeve.  
     CONSTITUTION: In the arrangement of direct-acting servo valve of this invention, a homogeneous resilient material 6 like rubber having internal damping effect is interposed between bobbin 7 and support metal 10. The resilient material 6 is connected at its left end to bobbin 7 and at its right end to support metal 10. With such an arrangement, if current is passed in coil 8, there is exerted a proportional force for driving spool 1. However, since resilient material 6 has a great internal damping effect, peak of the resonance is low and stable, so that spring constant of resilient material 6 is not required to be so large. Further, since characteristics of resilient material 6 is uniform, any deflective force is not developed when a force is acted thereto, which results in reduction of frictional force acted between spool 1 and sleeve 4. Thus, it is enabled to obtain a servo valve excellent in its responsibility and controllability.

Abstract: PURPOSE:To reduce the fuel basic unit of a furnace and stabilize the productivity and quality of  steel strips to be heated by obtaining the temperature and residual staying time of steel strips in preheating, heating, and soaking zones of a heating furnace and then correcting properly the  temperature of each zone according to the obtained data. CONSTITUTION:In a multizone type continuous heating furnace consisting of a preheating zone,  a heating zone, and a soaking zone, steel strips of different shapes and sizes are heated to respective target temperatures. The temperatures of steel strips in each zone are obtained from the  temperatures of the three zones, the characteristics of the furnace, and the thermal characteristics  and heat hysteresis of steel strips to be heated. Furthermore, the residual staying times of steel  strips in each zone are obtained from the positions of steel strips, the positions of steel strips going ahead in the extracting direction, and the extracting pitch of steel strips. Then, the corrections DELTATli for the temperatures of each zone for each steel strip are obtained to determine the corrections DELTATl for the temperatures of each zone. In this case, using the corrections DELTATli for  the temperatures of each zone for each steel strip and also the weight coefficient Wli determined according to the magnitudes of DELTATli and DELTATl, the corrections DELTATl for the temperatures of  each zone are determined by the equation [I], where n is the number of steel strips to be heated  in the zone l.

Abstract: PURPOSE:To easily generate various voltages by rectifying an AC power source to DC power smoothed into output voltage detecting its level and DC/DC converting the level, when it is in a high value, decreased to the predetermined voltage driving an inverter. CONSTITUTION:An AC power source 3 is rectified by a rectifier 4 obtaining a pulsating current smoothed by a smoother 5 and input to a DC/DC converter 6. The converter 6 is controlled in its DC output voltage by turning a transistor TrT on and off, driving an inverter 2 to output VVVF rotating a motor 1. A voltage detecting means 12 detects the DC output voltage of the converter 6, and an addition means 14 contains a phototransistor PT of the detecting means 12 added by an adder 21 with an output of a transmitting circuit 13 input to a level discriminating means 16. The detecting means 12 detects a level, when it is higher than the predetermined level, the output of the transmitting circuit 13 is decreased, and on-time of the transistor TrT is reduced by controlling a driving output 18 of the discriminating means 16. Thus, a single set of device generates various voltages required.

Abstract: PURPOSE:To reduce the size of a pulse transformer and to speed up its operation and to use it for PWM sufficiently by operating the pulse transformer only during the on/off switching of a power MOS.FET. CONSTITUTION:When the pulse transformer generates a pulse voltage +Vd1 (V) with width ta (us) at its secondary side is response to the off-to-on transition of a PWM signal at time t1, a transistor (TR) 4 which is biased positively through a resistance 5 turns on to ground the gate of a MOS.FET 2 and then a diode 6 turns on; and the gate-source voltage VGS1 rises as an equivalent gate input capacitor Cin1 is charged, and when the voltage exceeds a gate-source threshold voltage Vth1, the power MOS.FET 1 turns on. When the equivalent gate input capacity Cin1 is charged sufficiently and the gate-source voltage VGS1 reaches VD1 diodes 6 and 9 turn off and the power MOS.FET 1 holds itself on continuously. Consequently, the PWM driving of the power MOS.FET is performed by using the pulse transformer and the duty cycle of pulses of PWM which can be driven is widened.
