Title: Horizontal afc circuit
Inventor: WATANABE MASAHIRO
IPC: H04N5/12
Filed: 1982-12-20
Abstract: PURPOSE:To assure the operation of a horizontal AFC circuit even in a vertical synchronizing pulse period by using a pseudo composite synchronizing signal obtained by inverting the polarity of a vertical synchronizing pulse contained in a composite synchronizing signal. CONSTITUTION:The composite synchronizing signal applied to an input terminal 1 is supplied to a vertical pulse extracting means 2, and a vertical pulse having a period equal to a vertical synchronizing pulse is led out to an output terminal 3 of the means 2. This vertical pulse is applied to an input of an exclusive OR circuit 4; while a composite synchronizing signal is applied to the other input of the circuit 4. Therefore a pseudo composite synchronizing signal obtained by inverting the phase of the composite synchronizing signal is delivered to the output of the circuit 4, i.e., an input terminal 5 of a phase comparator 6. The comparator 6 compares the composite synchronizing signal with a sawtooth wave supplied a comparison input to a terminal 8. The difference radio wave or difference voltage produced from said comparison is transmitted to a control terminal 10 of a horizontal oscillator via a smoothing circuit 9.

Title: Diaphragm for ultrasonic wave oscillator
Inventor: SHIBATA HAJIME
IPC: B06B1/02
Filed: 1983-11-30
Abstract: PURPOSE:To improve the errosion resistance of a diaphragm for ultrasonic wave oscillator by selecting the synthetic resin which is easy to process with a fixed level of standard in terms of a physical constant among those put on the market and using it to the diaphragm. CONSTITUTION:The synthetic resin having the E/rhoc value of <=2,000(m/sec) is used, where E shows the Young's modulus, rho is the material density and c is the sound speed transmitting through the material. For instance, a horn 1 having a frequency 19.5kHz is prepared and vibrated for 20hr with the vibration amplitude kept at 10mup-p at the end surface of a test piece 2. In such a case, the reduction factor eta due to the erosion is shown as eta=(A-B)/AX100(%) in terms of weight, where A and B are the weight of the piece 2 shown before and after a test. The synthetic resin having small E/rhoc value has a small degree of weight reduction due to erosion when the experimental result of eta is taken into consideration with a parameter of E/rhoc. In particular, the weight reduction factor is about 20% or less with <=2,000E/rhoc. This shows a standard of a safe area for practical use.

Abstract: PURPOSE:To drop and circulate a mixed solution of a lithium halide and a lower alcohol through a preheated lower alcohol, by reducing the pressure of a closed vessel containing a solid lithium halide sealed therein, flowing the preheated lower alcohol from the bottom of the vessel, and forcing the lower alochol to come into contact with the solid lithium halide. CONSTITUTION:A lower alcohol, e.g. methanol, is poured into an alcohol reservoir 2, and a solid lithium halide, e.g. anhydrous lithium bromide, is put into an absorbent holding part 7. Flanges 14 and 15 are then fixed, and a vacuum valve 22 is opened to reduce the pressure in the interior of a vessel shown in the figure. Water is then passed from the outside of a condensing part 16, and heated by a heater 5 to boil vigorously the alcohol. The boiling alcohol vapor is then passed through a blowing pipe 12, and the absorbing solution and alcoholic vapor collide with the absorbent in the holding part 7. The vapor is absorbed in the absorbent to form an absorbing solution, which dissolves the absorbent to become a concentrated solution. The resultant concentrated solution is passed through a mesh 8 and a return pipe 11 and dropped to the reservoir 2. EFFECT:The aimed absorbing solution of high purity is obtained in a short time without using any mechanical driving part.
