Abstract: PURPOSE:To ensure not only the steady operation but the miniaturization of the circuit, by performing the relay driving with the pulse current to reduce the power consumption of the timer circuit and then eliminating the effect to the electronic  parts which is caused by the heat generated through the continuous conduction for  a long time. CONSTITUTION:The 1st SCR1 is connected to the input terminal of the commercial power source via the rectifying diode D3 and the resistance R1, and then the serial circuit of the reverse current preventing diode D1 and the capacitor C4 is connected in parallel to the SCR1. And the terminal voltage of the capacitor C4 is applied to the gate of the SCR1 via the resistance R8, and then the base of the switching transistor TRQ connected between the gate and the cathode of the SCR1 is connected to the voltage dividing point between the split resistances R6 and R7. In addition, the serial circuit of the 2-winding type bistable relay Ry, the relay driving capacitor C5 and the 2nd SCR2 is connected in parallel to the SCR1. And the diode D2 is connected in reversely parallel to the SCR2. At the same time, the voltage of the time constant circuit T is applied to the voltage comparator COMP via the smoothing circuit L, and the output terminal of the COMP is connected to the gate of the SCR2. Thus the relay Ry is driven by the pulse current.

Title: Copying device
Inventor: KITAMURA TAKASHI
IPC: B41J2/44
Filed: 1980-09-24
Abstract: PURPOSE:To obtain a smooth picture which has the noise due to quantization is eliminated, by causing the ouput, which is quantized in respect to time, of a discrete read element to pass through a low pass filter. CONSTITUTION:The output of a read element 6 has a pulse amplitude modulated waveform as shown in figure (a). This pulse amplitude modulated wave passes through a low pass filter 7. At this time, the cut-off frequency of the filter 7 is half or less of a sampling frequency, namely, the read clock frequency generated by a clock generating part 21. Therefore, a waveform of the original picture signal as shown in figure (b) is obtained by the Shannon's sampling theorem. Thus, the defect of the ruggedness in the picture peripheral part is resolved. Further, even if a noise is superposed onto the read signal, it is eliminated by the filter if it is a high frequency noise.

Filed: 1984-06-28
Abstract: PURPOSE:To obtain the ignition timing which is always constant even if the revolving speed of an internal-combustion engine varies, by putting a switching element into electric conduction by the negative half-wave output of a charging coil and bringing a thyristor into electric conduction by the output of a power- source condenser.

Title: Origination control system for automobile telephone
Inventor: TAKAGI MASAKI
IPC: H04M1/00
Filed: 1987-05-29
Abstract: PURPOSE:To avoid such inconvenient cases where a warning tone surprises abruptly or the cell charge is extremely increased without notice, by performing the ring-off processing in the case an origination key of an automobile telephone is kept turned on for a fixed time or longer so that an undesired origination state is automatically released. CONSTITUTION:The ON time is counted for keys related to transmission and set to a handset of the automobile telephone and the ring-off processing is carried out when said ON time exceeds a fixed level. It is rare in a normal transmission operation to depress continuously the related keys (a normal mode start key K2, an abbreviation mode dial key K1 or a dial key K3) for a long time. Thus it is possible to prevent such a case where an undesired transmission state (off-hook state or circuit connection state) lasts for a fixed time or longer by having the automatic ring-off processing when such said keys are kept turned on for a fixed time or longer. As a result, no warning tone is needed for information and the call charge increased for a long time can be avoided.

Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To improve the precision of a cell gap and to reduce the consumption of a gap material by transferring the gap material sucked to each of plural suction holes to a substrate to scatter the gap material on the substrate. SOLUTION: A pressure in a pressure reducing chamber 632 is reduced by an evacuation device A and a gap material 41 is sucked from a gap material storage chamber 640 toward each of suction holes 69 of a suction head plate 68 and the gap material 41 is sucked to each of the suction holes 69 one by one. Then, a gap material supply box 64 falls and a gap material scattering head 63 is moved up to a position just above a large-sized substrate 100 along guide shafts 61 and 62. Thereafter, a three-way cock 66 is switched to disconnect the evacuation device A with the reducing chamber 632 and the reducing chamber 632 is opened to the air. As the result, the gap material 41 sucked to the suction holes 69 of the suction head plate 68 releases from the suction holes 69 and is dropped to the large-sized substrate 100 by its own weight as t is.  Thus, the gap material 41 is scattered only in prescribed positions on the large- sized substrate 100.

On the other hand, an elastic surface wave is generated on the surface of a sample by the ultrasonic beam and the echo thereof is captured on the surface of lenses 11b, 11c and received by corresponding piezoelectric membranes.  Traveling time of elastic surface wave can be determined based on the difference of receiving time between the piezoelectric membrane 12a and the piezoelectric membrane 12b or 12c and the velocity of elastic surface wave is calculated based on the traveling time thus determined without displacing the sample or the ultrasonic probe.
