Title: Automatic irrigation apparatus
Inventor: TSUCHIYA TAKESHI
IPC: A01G27/00
Filed: 1992-02-20
Abstract: PURPOSE:To provide the subject apparatus provided with a water sensor having a specific construction, capable of accurately detecting the water content of the irrigation object owing to the resistance of the water sensor to galvanic corrosion caused by fertilizer, etc., in soil and effective in keeping the irrigation rate to the optimum level. CONSTITUTION:When the water content of an irrigation object is decreased, the water 45 sealed in a vessel 43 constituting a water sensor such as a tension meter 4 seeps through the porous part 44 at the tip end of the vessel 43. The extent of the seepage is detected by a detection element such as a pressure sensor 41 constituting the water sensor to detect the deficiency of the water in the irrigation object. An irrigation means is driven or stopped by a controller based on the detection signal transmitted from the water sensor. The vessel 43 is made of e.g. vinyl chloride resin and the porous part 44 is made of e.g. ceramics.

Title: Pattern inspection device
Inventor: AKIYAMA CHUJI
IPC: G06T1/00
Filed: 1988-02-16
Abstract: PURPOSE:To facilitate an inspection for a defect in the pattern of an object to be inspected with a simple composition by irradiating light on the object to be inspected, making its reflected light into parallel through a collimator, converting the light into an electric signal, and detecting the defect in the pattern. CONSTITUTION:A collimator 16 is arranged close to a printed wiring board 10, the light to pass through the collimator 16 is made into incident light onto linearly arranged many LEDs 17a and 17b, and a generated charge is outputted through a transferring gate 18 to a picture processor 19. The collimator 16 has many holes linearly arranged in a direction rectangular to the board 10, passes only components, which are parallel to the holes, out of the reflected light of the printed wiring board 10 by light L, and prevents the fuzziness of an image. Further, since the photographed pattern of the printed wiring board 10 is image-formed with the magnification of 1, it is unnecessary to correct the pattern. Thus, the defect in the pattern of the object to be inspected can be easily detected with the simple composition.

IPC: B60W10/10
Filed: 1987-02-16
Abstract: PURPOSE:To prevent danger beforehand by switching a stepping pedal to the neutral position by the stop of speed change operation, even if a manual lever is selected to the forward or rearward high seed position, in the traveling operation device for combine, etc. CONSTITUTION:When a manual lever 3 is operated from the neutral speed change position to the forward speed change side or rearward speed change side, a hydraulic continuously variable transmission 1 is operated to the forward speed change side or rearward speed change side through a manual interlocking mechanism 4 and a speed change operation shaft 2. Though, even if the manual lever 3 is at any speed change selecting position, the forward/rearward speed change operation by a stepping pedal is permitted by a preference mechanism 7, the manual lever 3 can be switched to the neutral position by a neutral switching mechanism 7a, when the speed change selection by the stepping pedal 5 is set to the deceleration speed side or retreat side rather than the forward speed side by the manual lever 3 or in the reverse case. Therefore, the advance or retreat at a high speed is prevented, and generation of danger is suppressed beforehand.

Title: Device for monitoring abnormal vibration of equipment
Inventor: TAKAMI HIROSHI
IPC: G01M99/00
Filed: 1981-03-09
Abstract: PURPOSE:To make it possible to capture even momentary abnormal signals and to detect the abnormal state of the equipment in an early stage, by converting a clipping signal of a frequency signal corresponding to the abnormality into an alarm signal having a preset time length. CONSTITUTION:When the mechanical vibration output detected by a sensor 1 and a vibration amplifier 2 is judged to be abnormal vibration by HPF3a1 and LPF3a2 in a signal processing device 3, frequency signals are outputted from the device 3. The judgement is based on whether the number of said vibrations is located in the normal vibrating frequency region or not. Said outputs are clipped at a preset level in clippers 5b1 and 5b2 in an alarm device 5. The waveforms of the part of the sinals which exceed a specified level is shaped in trigger circuits 5c1 and 5c2, and the trigger signals are applied to driving circuits 5d1 and 5d2. In this way, said circuits 5d1 and 5d2 generate the alarm signals whose time length is set so as to drive the alarm circuit. The abnormal vibrations which occur intermittently and momentarily can be captured without fail and the fault of the equipment can be detected in the early stage.

IPC: G10H1/06
Filed: 1978-03-25
Abstract: PURPOSE: To provide an electric piano which generates the tone similar to that of a cembalo with a simple constitution by processing sound source signals with a higher harmonic generating circuit, filter, etc.  
     CONSTITUTION: When the sound source signals corresponding to the striking vibrations of the electric piano detected with a pickup 1 are applied to a higher harmonic generating circuit 2, the circuit 2 makes multiplication processing of the signals and generates a multiplicity of higher harmonic signals for the basic waves of the sound source signals. When these signals are processed with a special filter 3 being an HPF of high vibration characteristics, they are removed of unnecessary frequency components and become the musical tone signal corresponding to that of the cembalo formed with higher harmonic components. The similar results may also be obtained even if the multiplication processing is accomplished with a voltage control type amplifier.

Abstract: PURPOSE:To remove water completely after defrosting by coating a heater and a heat storing material with an insulating material and providing a water absorbing material exposedly on the surface of this insulating material. CONSTITUTION:An heater 1 is energized in advance so that a heat storing material stores heat. During defrosting, the exposed face of a water absorbing material 4 provided on an insulating material 3 is pressed and moved on the window of a car.
