Abstract: PROBLEM TO BE SOLVED: To increase the output turning to a DC power source without changing an internal transformer of a DC/DC converter by rectifying a pulse voltage generated in a primary side coil, and outputting the voltage as a DC voltage power source. SOLUTION: In a DC/DC converter requiring a plurality of outputs, a transformer constituted of a primary coil 11 and a secondary coil 12 is installed. The collector of an NPN type transistor Tr1 is connected with the primary coil L1 in which a DC voltage is inputted. Diodes D1, D2 are connected with contacts (b), (c) of the secondary coil L2, and a contact (a) is grounded. In such a DC/DC converter, the output signal of an output terminal 4 is fed back to a control circuit 2. As a result, the timing of turning on and off of the transistor Tr1 is controlled, corresponding to the output signal. When the transistor operates, VIN is applied directly to the primary side coil L1, so that energy is stored in the primary side coil, and this is supplied as a voltage.

Title: Manufacture of cathode-ray tube
Inventor: KOBAYASHI SHIGERU
IPC: H01J9/44
Filed: 1984-11-05
Abstract: PURPOSE:To obtain a cathode-ray tube with excellent high quality by raising a heater voltage than the rated value in the initial stages of raster aging process. CONSTITUTION:After applying a voltage Ef1 which is 1.1 to 1.2 times the rated voltage to the heater 9a-9c, the rated voltage or a voltage Ef2 which is lower than such rated voltage is applied during about 1/3 from the beginning of total period of the raster eging process 104. The first application of a voltage Ef1 which is higher than the rated voltage is necessary to recover the electron radiation capability deteriorated because impurity gas generated in the spot knoking process 103 adheres to the cathodes 10a-10c. The successive application of rated voltage or a voltage Ef2 which is lower than rated voltage is carried out to prevent that the electron radiation capability of cathode is remarkably deteriorated if the oxidation gas and halogen gas enter the inside of color picture tube and to enhance the capability of detecting impurity gas entering the inside of picture tube because the cathode, when it is low in temperature, is easily influenced by the effect of impurity gas. Thereby, a cathode-ray tube having excellent high quality by receiving electron radiation capability can be obtained.

Title: Automatic measuring apparatus for acoustic space
Inventor: NOGUCHI TETSUHIRO
IPC: G01H17/00
Filed: 1991-09-11
Abstract: PURPOSE:To make it possible to measure accurate sound at the optimum volume in any case by gradually increasing the level of a measuring reference signal from the minimum value until the strength of the measured signal agrees with the reference value stored beforehand. CONSTITUTION:The volume of sound from a reference sound source (PNG) 6 can be changed with a volume means (VOL) by the control of a digital signal processing means (DPS). The level of a measuring reference signal 2 is gradually increased from the minimum preset value through the volume means (VOL). The measuring reference signal 2 is inputted into an object to be measured 1. An analog measured signal 3 obtained from the object 1 undergoes A/D conversion 4. The result is compared with the reference value of the strength of a measured signal, which is stored in the DPS5. When the signal agrees with the reference value, the VOL7 is fixed. The measurement of the sound of the object 1 is started by using the measured reference signal 2 at that time. Thus, the difference in measured volume caused by the difference in gain of amplifier for regenerating the reference sound source and the difference in distance between a microphones and a speaker is eliminated, S/N can be made approximately constant and the stable measuring accuracy is obtained.

Title: Signal processing method for determining base sequence of nucleic acid
Inventor: HASHIUE MASAKAZU
IPC: G01N33/50
Filed: 1985-10-19
Abstract: PURPOSE:To obtain the base sequence of nucleic acid with high accuracy, by calculating a migration speed on the basis of the temp. of a support medium in a separation/development process and correcting the strain of a migration distance due to a smiling phenomenon on the basis of the migration speed. CONSTITUTION:Constant interrelation is present between the temp. T of a support medium and the migration speed (v) of a specimen as shown by a drawing. The temp. of the gel support medium is measured by a microthermistor or an infrared thermometer. From the calibration curve of the drawing, the migration speed v(x') corresponding to each inputted measured temp. T(x') is immediately led out. Next, the position of a band is determined with respect to each band and the migration speed (v) at said position is determined. Subsequently, the position of the band is corrected on the basis of said migration speed. That is, a migration speed d(x') is calculated from the position of each band and the arithmetic operation of Formula is performed to convert said calculated distance d(x') to distance D(x') which will be considered to be inherently migrated if no smiling phenomenon is generated.

Title: Measuring apparatus for mixing ratio of fuel for internal combustion engine
Inventor: YAMADA YOSHIRO
IPC: G01N21/43
Filed: 1988-09-19
Abstract: PURPOSE:To optimize the mixing ratio of a mixed fuel, by a method wherein the part of a light-transmitting body dipped in the mixed fuel is shaped in a curve. CONSTITUTION:The part of a light-transmitting body 1 used for measuring a refractive index, i.e. an optical waveguide, which is dipped in a mixed fuel 2 is made to be an optical waveguide shaped in a curve having a curvature. By the method wherein the part of the optical waveguide dipped in the fuel is shaped in the curve having the curvature, a light transmitted straight from a light-emitting element 12 to a light- sensing element 13 is eliminated. A light incident on the curved part of the optical waveguide at every incident angle is reflected repeatedly in a plurality of times at the same reflection angle on the interface between the waveguide and the fuel, and as the result, all the lights not meeting the condition of total reflection leak outside the optical waveguide and are not sensed. By these two effects, the quantity of transmitted light taken out as a light-sensing signal is made to be dependent on the refractive index of the fuel at 100% substantially, and therefore the sensitivity of a sensor, i.e. S/N, is increased. Based on the output signal of the element 13 being dependent on the refractive index of this fuel 2, the mixing ratio of the fuel 2 is measured.

IPC: H04B7/26
Filed: 1990-09-04
Abstract: PURPOSE:To identify a mobile station without increasing the operation by a driver by discriminating a type automatically when a radio signal to identify the type sent respectively from a stationary station is received and sending a specific code or a pseudo code generated at application of power to the stationary station. CONSTITUTION:A mobile station compares a type of a received stationary station with a type of a stationary station stored in a storage means 164 to identify the stationary station and when they are coincident, the mobile station sends automatically a specific code assigned in advance to its own station. When the mobile station enters a communication area of the stationary station able to use a pseudo code like a traffic flow grasping system, a stationary station identification means 174 identifies the type and sends a pseudo code generated at application of power of a mounted radio equipment automatically for the reply. As a result, the system such as traffic flow grasping system detects only information of the mobile station and effective information is given to the system only without matching the identification with the other connected system.
