Title: Method and device for measuring phase difference of acoustic wave
Inventor: MATSUSHIMA HARUO
IPC: G01H3/00
Filed: 1993-06-30
Abstract: PURPOSE:To compute the temperature difference or the like independently of other influence by applying the alternating current of a fixed frequency to an acoustic wave oscillating element having the same resonance frequency for a short time, and receiving it with two receiving elements having the same resonance frequency, and taking out a detected phase difference between both the elements per predetermined time. CONSTITUTION:An alternating current generating device 1 is formed of an alternating current source 2, for example, of 40kHz and a switch 13, which can be closed like a pulse. An alternating current is applied to an acoustic wave generating element 4 for a very short time, and the fine acoustic waves received by opposing acoustic wave receiving elements 6, 7 are amplified by tuned amplifiers 8, 9, and the amplified acoustic waves are applied to a phase difference detecting device, which is formed of comparators 16, 17 and an exclusive OR gate 18. On the other hand, a phase difference is taken out by a means, which is formed of a monostable multivibrators 5, 20 and an AND gate 19 and which detects a phase difference in a predetermined time, during the time from the starting of receiving of the acoustic wave by the elements 6, 7 till the reflected wave is received. This phase difference appears with a change of the sound speed in the wet air and the dry air, and the humidity of the air can be measured by detecting this phase difference.

Title: Recorder for information signal
Inventor: SHIONO KOICHI
IPC: G11B15/087
Filed: 1987-06-30
Abstract: PURPOSE:To attain high speed reproduction by using a constitution so that a control signal used for a retrieval signal for an information signal is made up of 1st and 2nd reference signals, thereby utilizing each reference signal effectively in the signal reproduction mode. CONSTITUTION:An information signal Sa reproduced from a magnetic head HL is fed to a muting circuit 32 via an equalizer amplifier 31 and outputted (34). On the other hand, a queue signal Sq reproduced by a magnetic head HR is fed to a signal conversion circuit 36, where the signal is converted into a rectangular wave signal. Thus, a reproduced CUE signal Sq' is obtained at an output terminal 37 as shown in figure E or F and the signal is used also as a muting signal to the circuit 32. In the high speed reproduction mode, since the 2nd reference signal S2 has a frequency at the outside of the reproduction band, it cannot almost be reproduced and only the 1st reference signal S1 is reproduced. In the high speed reproduction, the reproduction CUE signal Sq' with a polarity shown in figure F is obtained, thereby applying muting for the information block period. Thus, the program search of the information block is attained by detecting the leading edge of the reproduced queue signal Sq'.

Title: Driving circuit for transistor
Inventor: KOTOU NOBUYOSHI
IPC: H03K17/60
Filed: 1978-12-26
Abstract: PURPOSE: To reduce the switching loss of a main and a driving transistors and expand the range of voltage control, by searately applying a forward and a reverse biases to the transistors Darlington-connected to each other.  
     CONSTITUTION: When a signal for opening a driving transistor 4 is supplied from a control circuit 11 to the primary winding 10 of a transformer 8, a voltage is produced so that the terminals of the secondary winding 9 and tertiary winding 20 of the transformer represented by dots in Fig. are negative. At that time, a reverse bias is applied to the transistor 4 by the voltage of the secondary winding to open the transistor. Another transistor 16 is closed because the base current flows through the tertiary winding 20 and a resistor 19. A main transistor 2 is opened because a reverse bias current flows through a power source 22, the transistor 16 and a resistor 21 synchronously with the driving transistor 4. The reverse bias current can be optionally set by the power source 22 and the resistor 21 to shorten the storage time. The base current I 1  of the transistor 4 flows through a shortest loop and is not affected by a wiring inductance or the like. This results in reducing a switching loss and expand the range of voltage control.
