Title: Improvements in or relating to piezo-electric crystal oscillators and resonators
Inventor: MORTLEY WILFRID SINDEN
IPC: H03H9/13
Filed: 1953-04-10
Abstract: 730,688. Piezo-electric crystals. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 17, 1954 [April 10, 1953], No. 9828/53. Class 40 (8). A piezo-electric crystal unit comprises a flat crystal plate K and opposed metallic electrodes in the form of strips TE, TB at an angle to one another and crossing over beyond one another in projection so that the effective electrode area E is less than the strip area of each electrode. Since the effective electrode area E does not vary with the position of the strips and varies negligibly with the angle between them it is possible to maintain a standard electrode area from one unit to the next and thus produce units having predictable and repeatable inductance values. The crystals and the strips may be of various shapes and the strips may extend completely across the faces of the crystals (Figs. 1, 3, not shown). The effective electrode area may be square or rectangular. The electrodes may be produced by sputtering or evaporation using an adjustable mask. The invention is applicable to crystals vibrating in either the thickness-shear or face-shear mode.

Title: Electrical vehicle braking system
IPC: H02P3/20
Filed: 1971-04-19
Abstract: 1319039 Control of D.C. motors EATON YALE & TOWNE Inc 19 April 1971 [30 April 1970] 9974/71 Heading H2J In an electric vehicle driven by a pulsed D.C. current, when the brake member 20 is depressed a Direction Sensor circuit (D.S.) determines whether the vehicle is moving forward or backwards then applies the current to the field winding 30 in the opposite direction, and as the brake is further depressed increased braking current is applied. When the brake is depressed to its limit a switch LS-2 is opened and an additional mechanical brake is applied. Current from a battery source B normally flows through a potentiometer-accelerator 42 to a Pulse Control circuit (P.C.) and hence to the motor M and field winding 30. The mechanical brake is normally held off biased against a spring by a solenoid 162. The output from a tachometer 50 is taken to a Direction Sensor circuit (D.S.), the output of which (indicating both the direction and speed) is applied to a Current Direction control circuit (C.D.) which is in two parts, 66 for reverse movement and 68 for forward movement. When the brake 20 is depressed a switch LS-1 is immediately closed to energize relay CR1-C and close or open all its normally open or closed contacts respectively. The brake potentiometer 28 is brought into circuit, as is the Pulse Stretcher and the appropriate C.D. circuit, depending on whether the vehicle is moving forward or backwards. The appropriate relay (CR3-C or CR4-C) closes the appropriate contact (CR3-1 or CR4-1) to reverse the current through the field winding 30, and as the brake is depressed further the pulse frequency is increased and the Pulse Stretcher increases the pulse width. If the vehicle is stationary when the brake 20 is depressed closing switch LS-1, the Motion Sensing circuit (M.S.) detects no output from the C.D. circuits so relay CR2-C disconnects these circuits from the battery and applies the mechanical brake 36 by opening CR2-2 to de-energize the solenoid. Also, if power is lost or the dead man switch S-3 is opened the solenoid is de-energized and the mechanical brake is applied. To reverse the direction of the driving current for normal operation switches S-1 or S-2 are provided to reverse the current through the field winding.

Title: Mixing device for hot and cold water
Inventor: KIDOUCHI YASUO
IPC: F16K11/085
Filed: 1985-01-08
Abstract: PURPOSE:To prevent boiling water from being delivered by a method wherein a controller, which performs the delivery, stop and temperature control of mixed water by driving a mixing valve based upon the signal of a presetter, is provided. CONSTITUTION:When a controller 33 receives the signal to stop the delivery of hot water from a presetter 32, the controller 33 drives a mixing valve 30 in the direction to close a hot water side flow passage 14 in order to close the hot water side flow passage 14 and further drive the mixing valve in the same direction, resulting in gradually close the opening of a closing valve part 34, which is made between a water side closing valve seat 28 and a water side valve body 17 in order to stop the delivery of mixed water. When the delivery of hot water is started, the mixing valve is driven in the direction opposite to the above- mentioned direction, resulting in opening a water side flow passage 16 and, after that, the hot water side flow passage 14 is open so as to coincide the temperature of mixed water with the indicated temperature. At the delivery of hot water, at first the cold water is delivered and, after that, the hot water controlled to the desired temperature is obtained. At the stop of the delivery of hot water, at first the delivery on hot water side is stopped and the complete stop is done by stopping the delivery on cold water side. Thus, even when the delivery and stop of hot water is repeated or when the delivery of hot water is intended after being left in the once stopped state for some period of time, no fear of the supply of boiling water exists.

Title: Variable resistance circuit
Inventor: KABAYAMA YOUZOU
IPC: H03G1/00
Filed: 1981-01-08
Abstract: PURPOSE:To extend the dynamic range, by using diodes with inverse characteristics mutually as resistors. CONSTITUTION:A diode D2 with inverse characteristics in DC and AC as a diode D1 connected complementarily. The diodes D1 and D2 are connected in series in DC manner to a variable current source IF, but in parallel in AC manner. Thus, a resistive component viewed from an output terminal OUT is a parallel combined resistance of resistive components dVF/dIF of the diodes D1, D2. When a signal is applied from an input signal source Vin, the diodes D1,D2 take inverse characteristics DC and AC manners. Since the D1, D2 act complementarily, the  parallel combined resistance of the both shows a slow change to the alteration  of an input signal. Thus, the change in the output impedance is small. As a  result, the dynamic range can be made wider and the distortion can be reduced.
