Filed: 1984-01-10
Abstract: PURPOSE:To decrease the shift of indication at UHF band by using a variable resistance element with an intermediate tap and a switching element to adjust a voltage thereby interlocking the band display of low band VL and high band VH of the VHF band. CONSTITUTION:A tuning voltage at the reception of the VL, VH and UHF is switched by a band switch 1 and a variable resistor element 2 and applied to terminals LB, HB and UB. At the VL, transistors (TRs) TR1, TR2 are turned off, a voltage at an intermediate tap point C is decided by a VR2 and a voltage at a point (b) is decided by an R3. At the VH, the TR1 is turned off and the TR2 is turned on, the voltage at a point (a) at the VH is decided by the VR1 deciding the voltage at the point (a) at the UHF and a voltage at the point C is decided by a VR3. The TR1 is turned on and the TR2 is turned off at the UHF and the R1 decides the voltage at the point (b) and the VR4 decides the voltage at the point C. Thus, the number of components is decreased, the band display of the VL and VH is made continuous to decrease the pointer shift at the UHF.

Title: Polarization device of piezoelectric body
Inventor: KIMURA YOSHIMICHI
IPC: H01L41/257
Filed: 1985-01-11
Abstract: PURPOSE:To prevent dielectric breakdown due to transient high voltage applied on piezoelectric bodies in a device, in which a DC voltage is applied for polarizing the piezoelectric bodies, by providing a resistive or inductive load between each electrode contacting with each piezoelectric body and the output terminal of a DC transformer. CONSTITUTION:A piezoelectric body 2 is mounted at specified position of each conductor substrate 46 of a jig 45 by a conveying mechanism and held by a conducting terminal 50, which is fixed to an upper plate 48, and the substrate 46. Then the piezoelectric body 2 is conveyed under the state it is held by the jig 45. The body 2 is connected to output terminal 69 and 70 of a voltage source 71 of a DC transformer and the like. A voltage is applied and polarization is performed. A resistor 55 (an inductive load can be used) is connected between a feeding terminal 56 of the jig 45 and each conducting terminal 50. Even a transient high voltage is generated in the voltage source 71 accompanied by the load fluctuation between the output terminals 69 and 70, said high voltage is absorbed by the resistors 55. Therefore the high voltage is not applied to the piezoelectric bodies 2. Since the dielectric breakdown of the piezoelectric bodies can be prevented, the polarization processes can be automated.

Title: Method for measurement of differential pressure
Inventor: TASAKA YASUO
IPC: G01L13/00
Filed: 1981-01-14
Abstract: PURPOSE:To make measurement possible irrespectively of the directions of flow of fluid by connecting a high selector and a low selector to the high pressure side inelt and low pressure side inlet respectively of a differential pressure detector. CONSTITUTION:If it is assumed that fluid flows from a pipe 1 toward a pipe 2, the side of a pressure conduit pipe 3 is high pressure side and the side of a pressure conduit pipe 4 is a low pressure side. Here, 8 is a high selector, and outputs the higher of the internal pressure  two inputs. In such piping as shown in the figure, the pressure of the pipe 3 is conducted to a pipe 5. A low selector 9 is designed to output the lower of the internal pressures of two inputs, and the pressure of the pipe 4 is conducted to a pipe 6. When fluid flows from the pipe 2 toward the pipe 1, the opposite takes place, thus the pressure of the pipe 4 is conducted to the pipe 5 and the pressure of the pipe 3 to the pipe 6. The pressure on the high pressure side is conducted always to the pipe 5 and the pressure on the low pressure side always to the pipe 6. These pressures are received in a differential pressure detector 10, and the differential pressure between the pipes 1 and 2 is measured irrespectively of the flowing directions of fluid.

IPC: H04J13/00
Filed: 1990-01-12
Abstract: PURPOSE:To obtain a highly practical spectrum spreading method which requires no synchronizing device by extracting and modulating a frequency which is twice as high as an intermediate frequency between a 1st spread spectrum signal and a 2nd spread spectrum signal. CONSTITUTION:An inputted voice is amplified by an amplifier 1 and a frequency converting circuit 2 imposes FM modulation upon a 2nd carrier from a 2nd carrier generating circuit 3 as well as normal FM transmission. A PN code generating circuit 4 generates a white noise and an FH signal generating circuit 6 imposes FM modulation upon a 3rd carrier from a 3rd carrier generating circuit 5. At this point of time, a PN code equivalent to an FH code is obtained and the spread band is determined unequivocally by the white noise and the degree of FM modulation. This PN code is distributed to a distributor 7 and led to the balanced modulating circuit 8 and 1st carrier balanced modulating circuit 10 of a voice input circuit. The circuit 8 imposes balanced modulation on the 2nd carrier with the PN code and then a spectrum shown in a waveform figure (a) is obtained, so a band-pass filter circuit 11 extracts only a lower wave band (f2) (waveform figure (b)).
