Title: Constant voltage source circuit
Inventor: KIZAWA MITSUTAKA
IPC: G05F1/567
Filed: 1984-03-30
Abstract: PURPOSE:To adjust the temperature coefficient of the constant voltage source circuit corresponding to reference temperature over a wide range by adjusting the gain of the 2nd operational amplifier which feeds the voltage across a circuit element back to the input side of the 1st operational amplifier. CONSTITUTION:The feedback loop of an operational amplifier OP1 is formed of resistances R4 and R5 and diodes D2 and D3, and the voltage across the diodes D2 and D3 is inputted to the input terminal of an operational amplifier OP2 through resistances R1 and R8. Further, the output voltage VS of the operational amplifier OP2 is inputted to the inverted input terminal of the operational amplifier OP1 and the Zener voltage of a Zener diode D1 is divided by resistances R6 and R7 and applied to the uninverted input terminal. Consequently, differential VZ/ differential T<<differential VF/differential T, where differential VZ/differential T is the temperature coefficient of the diode D1 and differential VF/differential T is the temperature coefficient of the diodes D2 and D3, so the temperature coefficient differential VS/differential T is varied over a wide range by varying the resistance value of the resistance R2.

IPC: H04B3/54
Filed: 1984-03-30
Abstract: PURPOSE:To allow a mutual communication between devices by providing two transmitter-receivers capable of automatic transmission/reception switching to a communication device which utilizes a commercial power source line, and allowing a transmitter-receiver which is not in a reception state to operate as a transmitter when a speech signal is inputted. CONSTITUTION:The FM transmitter-receivers 4 and 5 are capable of automatic switching between transmission and reception and their transmission/reception frequencies are f1 and f2. A control circuit 7 in calling operation switches, for example, the transmitter-receiver 4 to a transmission side with an off-hook signal from a terminal 6 and a speech signal is supplied to the transmitter-receiver 4 through a changeover switch 3. The transmitter-receiver 4 transmits an FM-modulated signal of frequency f1 to a power source line. An FM carrier f2 on the power source line is selected by a BPF9 and supplied to the transmitter-receiver 5. When the circuit 7 is supplied with neither a received signal nor a control signal from a terminal in answering operation, the FM wave f1 on the power source line is selected by a BPF8 and supplied to the transmitter-receiver 4. The transmitter-receiver 4 supplies a modulated signal to an adder 16 and the received signal is supplied to the control circuit 7. When a receiver is lifted, the control circuit 7 controls the transmitter-receiver 5 to a transmission side and also operates the switch 3. The circuit 7 once receiving the received signal displays that on a display device 19.

Title: Device for watering bottom surface of flower pot and watering using the same
Inventor: WATANABE MOICHI
IPC: A01G27/04
Filed: 1992-02-14
Abstract: PURPOSE: To provide a watering method similar to a natural environment for the healthy growth of a potted plant, and to provide a device therefor. CONSTITUTION: Two or more through holes are bored in the lid of a watering container. Both the ends of a string-like water-absorbing member are introduced into the through holes of the lid, and immersed in the water for watering in the watering container. A sheet is loaded on the upper surface of the string-like water-absorbing member, and a potted plant is further loaded on the sheet and subsequently cultured. Each of the through holes bored in the lid is holes somewhat larger than the width of the water-absorbing member, but the water-adsorbing member may directly be immersed in the watering container without boring the through holes. This method is advantageous for the production of crops in the farmhouse. A cheese cloth, cloth, paper, peat moth, etc., may be utilized as the sheet loaded on the water-adsorbing member.  Since the method can provide an environment similar to the natural one, the method has an effect to facilitate the growth of the roots of a plant. Thereby, the method is extremely effective for the healthy growth of the potted plant. Since the method is easily performed at a low cost, the application fields are wide, and the method can widely applied not only to the culture of various plants in farmhouses but also to the displays of flowers in flower shops, etc. The watering device is also suitable as a device for culturing a potted plant at home.

IPC: F26B13/24
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic dryer that can easily and securely dry liquid adhering to a thin film section. SOLUTION: A tip surface 10 is an ultrasonic radiation surface for radiating an ultrasonic wave, a standing wave is formed between the tip surface 10 and an ultrasonic-wave reflector 14, and a position that becomes the node of sound pressure is formed at specific intervals. Since a lead frame 1 moves while being inclined to the tip surface 10 and the ultrasonic-wave reflector 14 by an angle θ, a position that becomes the node of a sound pressure is allowed to coincide with at least one place on the lead frame 1, thus eliminating the need for accurately positioning the lead frame 1 to the position that becomes the node of the sound pressure between the ultrasonic-wave reflector 14 and the tip surface 10 as compared with a case where the lead frame 1 is arranged in parallel with the tip surface 10 and the ultrasonic-wave reflector 14.

Title: Controlling method of injection speed of shot plunger
Inventor: TANAKA MASAAKI
IPC: B29C45/00
Filed: 1983-04-07
Abstract: PURPOSE:To control quickly and exactly the injection speed of a shot plunger by measuring continuously said speed, calculating the average value obtd. by multiplying said speed by a coefft. at every shot, and correcting the opening of an injection speed regulating valve in accordance with said value. CONSTITUTION:The injection speed of a shot is measured in the prescribed shot plunger position of an injection molding device and the value thereof is recorded. When the number of the measured and recorded values attains a required number, a weight average value is determined by multiplying the measured value by a coefft. which has successively increasing numerical value. Whether the average value is within a permissible range or not is decided, and if the value is within a permissible range, the operation is returned to the original step and the shot is repeated. If the value exceeds a permissible range, the difference between the weight average value and the target value is calculated and the opening or closing degree of an injection speed regulating valve is corrected according to the difference, by which the injection speed of the shot plunger is controlled. The accuracy and yield of the product are improved by such controlling method.

IPC: G01B11/245
Filed: 1987-03-17
Abstract: PURPOSE:To improve aligning accuracy by so irradiating the outer peripheral side of a wafer with a luminous flux that an irradiating position is brought to a facet when a placed wafer is moved to the vicinity of an aligning position, and obtaining a rotation stopping position by detecting the reflected light. CONSTITUTION:A disclike wafer W having a facet F in which the outer peripheral side becomes a flat surface partly on the outer periphery is placed on a rotatably table 1 to be rotated to align the direction of the facet F to a predetermined direction. Here, the outer peripheral side of the wafer W is so irradiated with luminous flux 5 that the irradiating position is moved to the facet T when the placed wafer W is moved to the vicinity of the aligning position, and the rotation stopping position is obtained by detecting the reflected light 6. When the irradiating position is moved to the facet F by the rotation, the direction of the reflected light is moved due to flat surface upon rotation of the wafer W. Accordingly, the light 6 is detected at a predetermined position to obtain the rotation stopping position at a predetermined one point. Thus, the aligning accuracy can be improved.
