Title: Ultrasonic light modulator
Inventor: OOTA YOSHINORI
IPC: G02F1/11
Filed: 1979-07-24
Abstract: PURPOSE: To make speed high and efficiency high by arranging plural elastic materials of different velocities of sound between an acoustooptic modulating medium and a piezoelectric crystal plate symmetrically at the center thereby constituting an ultrasonic modulator.  
     CONSTITUTION: Ni5 and In6 are evaporated to 3μm thickness on one surface of an acoustooptic modulating medium 1 such as glass and dielecric and are so disposed that the respective centers thereof become symmetrically at an equal spacing. The metal films 5, 6 give a phase difference of π/2 to sound waves. A piezoelectric crystal plate 2 is provided thereon and electrodes 3, 4 are dividedly provided on said crystal plate 2 so that the direction of the elecrtic field applied on each converting element becomes opposite at every two as shown by arrows 7. If high frequency voltage is applied to the electrodes 3, 4, the parallel wave surfaces differing in phase by π/2 are produced in the adjacent sections 9, 10 of the modulating medium, whereby artificial wave surfaces 11, 12 are formed. This increases the incident angle θ of light 13 satisfying Bragg's conditions. Because of this, the speed of modulation may be increased and the speed and perfromance may be made high.

Title: Logic circuit
Inventor: OOBA OSAMU
IPC: H01L29/47
Filed: 1979-07-24
Abstract: PURPOSE:To ensure a high integration as well as a high-speed operation, by forming the inverter gate constituting a TTL logic circuit into such circuit constitution that can be stored into one land. CONSTITUTION:The collectors of transistors TRQ1, Q2 of inverter INV1 plus the cathode of diode Q3 all feature the N-type structure and thus can share N-type region 4. Thus one gate can be formed with one line and one isolation. Accordingly, the aluminum wiring is required only to both the input and the output, load resistance R1 and the like, and thus the connecting wirings of TRQ1, Q2, and others can be eliminated to reduce extremely the contact region. As a result, the occupied area per gate can be greatly reduced, which is very effective to realize a high integration of the LSI or the like. Furthermore, the logic amplitude is small along with Schottky barrier diode Q3 for speed-up purpose connected between the emitter and the collector of current switching TRQ2. Thus a high-speed operation is secured.

Title: Bar-code input auxiliary device
Inventor: HORIUCHI TERUO
IPC: G06K7/10
Filed: 1982-06-01
Abstract: PURPOSE:To reduce the electric power consumption of an apparatus containing a reader, by providing a light source of a light source sensor on the side of a bar-code to be read. CONSTITUTION:A bar-code table 1 is formed by sticking that which prints a bar-code and a character or a character-string corresponding to this bar-code on a glass plate or a transparent acryl plate which transmits light. Light of a lamp 2 of a light source is reflected by a reflector 3, and light is transmitted from the reverse side of the bar-code of the bar-code table 1. When a power source switch 4 is turned on, the lamp connected to a DC power source 5 is lighted, and the bar-code becomes a readable state. In case of reading the bar- code, the light source is not required on the side of a reader, light which transmits the bar-code table 1 instead of a reflected ray is photodetected by a photodetecting part of an optical sensor, and information can be inputted by the digital processing. Therefore, the burden of electric power of a bar-code reader can be reduced.

Title: Monopulse angle measuring radar device
Inventor: MORITA YOSHIKI
IPC: G01S13/44
Filed: 1990-04-09
Abstract: PURPOSE:To measure the angle of a target with high accuracy even if a reception system varies in level by calculating the angle of the target from the measured values of a different signal and a sum signal which are obtained from the same target and the current beam direction angle. CONSTITUTION:The measured values of the difference signal   and sum signal SIGMAobtained as to the same target and the current beam direction angle theta of a radar are stored in a storage circuit 5 and an angle calculating circuit 6 calculates the angle of the target from the measured values. Namely, the angle thetagammaof the target is found from (DELTA/SIGMA)1.theta2-(DELTA/SIGMA)2.theta2(DELTA/SIGMA)2(DELTA/SIGMA)1, where (DELTA/SIGMA)1 is a 1st measured value, theta1 the current direction angle, (DELTA/SIGMA)2 a 2nd measured value, and theta2 the current direction angle. When only one measured value is obtained for the same target, the angle is measured by using the monopulse sensitivity measured value of the target when plural measured values had been obtained before to improve the accuracy of the measured angle.

IPC: H02M3/155
Filed: 1981-06-18
Abstract: PURPOSE:To stabilize the circuit operation which depends on the load current, by changing the duty cycle of the pulse signal which controls the operation of the load current controlling element in accordance with the variation of the supply voltage. CONSTITUTION:A load current IL supplied from a power source 11 to a load 12 is supplied to the collector of a grounded-emitter transistor (TR) 14 installed in a load controlling circuit 21. In the circuit 21, a voltage detecting circuit 22 which detects the variation of the voltage of the power source 11, an oscillating circuit 23 which sets the duty cycle DTC of the pulse signal in accordance with the output signal of the circuit 22 and supplies a pulse phi2 of the duty cycle DTC set in the base of the TR 14, and a DTC controlling circuit 24 are installed. When the voltage of the power source 11 is detected by the circuit 21  and the voltage becomes low level, the electric current IL can be enlarged by  enlarging the DTC of the pulse phi2 and also enlarging the DTC of the switching  of the TR 14. When the voltage of the power source 11 becomes higher by electric charging, the electric current IL can be reduced by reducing the DTC of the pulse.

Title: Radio equipment
Inventor: KATOU KAZUMORI
IPC: H04B1/50
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To provide radio equipment where the number of the synthesis stages of a synthesizer is reduced and the synthesis loss of a transmission part is reduced by not using the synthesizer or using it at least in one stage with the transmission signal of plural carriers as a signal synthesized by a two wave synthesizer. SOLUTION: Two wave synthesizer 13-1 or 13-2 synthesizes the transmission frequency of four carriers at every two carriers and they are outputted through common units 25-1 and 25-2. Thus, the number of two wave synthesis times is one for the two carriers and therefore an insertion loss is reduced to about half. Namely, the loss can be set to 4.5 dB on the four carriers compared to the conventional loss of 9 dB. The insertion loss of a transmission filter contained in the common unit 25-1 or 25-2 can be realized to about 2 dB. Thus, the insertion loss against the four carriers can be reduced to about 6.5 dB (4.5 dB+2 dB=6.5 dB).

Title: Catheter having ultrasonic balloon for pressure assistance, and its manufacture
Inventor: KUSLEIKA RICHARD S
IPC: A61M25/10
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To expand a stent by a low pressure by a method wherein after expanding a balloon to a pressure which is close to the pressure required for the expansion of the stent but not more than the pressure, an ultrasonic wave is applied to the stent, and the stent is expanded. SOLUTION: An ultrasonic wire 13 is arranged between the outside of a balloon 15 and a stent, and a catheter 10 is constituted. A pressure is fed from a pressure source 19, and the balloon 15 is expanded to a pressure which is close to the pressure required for the expansion of the stent 18 but not more than the pressure. Then, by operating a converter 11 and a horn 12, an ultrasonic wave is applied to the stent 18, and the stent 18 is expanded. By this operation, the pressure from the pressure source 19 generates a bias stress in the stent 18, and the ultrasonic wave vibrates the stent 18, and periodically generates a distortion in the peripheral direction. This vibration energy deforms the stent 18 exceeding the yield point of a constituent metal. Thus, the stent 18 can be expanded by a low pressure.
