Patent JP-S63180576-A (JP)
Title: Wheel control device for moving agricultural machine
Inventor: ANAMI MASAYUKI
IPC: B62D51/00
Filed: 1987-01-22
Abstract: PURPOSE:To permit a machine body to travel smoothly even on soft soil, by supporting a swing case for vertically moving traveling wheels in the vicinity of an output shaft of a travel transmission case, the swing case accommodating a drive chain for moving the output shaft and the wheels. CONSTITUTION:When wheels 3 slip on soft soil and a machine body is prevented from traveling, a stretching force applied to a driving and stretching side of a drive chain 5 stretched between an output shaft 2 and wheels 3 is increased by an increase in a load caused when the wheels 3 subside when the drive chain 5 is more stretched. As a result, a tension arm 6 is projected outwardly against an elastic force. The action of the arm 6 actuates a brake 7, which causes a swing case 4 to rotate in response to the rotation of the output shaft 2 so that the wheels 3 are lowered to press a soil surface sufficiently. Therefore, a driving force of the wheels 3 to the soil surface is increased, while a lifting force is applied to the machine body on the contrary to reduce its resisting force against the soil surface, whereby the machine body can travel smoothly on a wet field with a soft soil surface.

Title: Bone fixing screw
Inventor: MATSUMOTO ATSUSHI
IPC: A61B17/00
Filed: 1994-02-07
Abstract: PURPOSE:To safely remove a screw without damaging a bone and to minimize a screw hole after removing the screw by providing a shaft body, which has a screw head at one end and made of a metal, with a screw thread made from a resin which is decomposed and absorbed in the living body. CONSTITUTION:A bone screw 1 is composed of a metal-made shaft body 4 having a screw head 3 with a dent 9 into which a wrench or screwdriver is inserted and a screw thread 2 made from a resin which is decomposed and absorbed in the living body. As the stress deformation or creep deformation in age of resin is higher in the tensile direction than in the compressed direction, the bone screw 1 is more safely and securely fixed than those which is wholly made from resin. In a space 6 among the bone screw 1, a bone piece 7, and a bone 8, a new bone tissue is expected to form and the screw may be more securely fixed. When the screw is removed, the screw thread 2 is decomposed and absorbed and replaced with bone, or the screw is reduced in strength due to a decomposition degradation, so it is only necessary to remove the metal- made shaft body smaller than the bone screw which has been grafted first.

Title: Cathode for electron emission
Inventor: YUHARA KATSUO
IPC: H01J1/20
Filed: 1985-01-30
Abstract: PURPOSE:To obtain a cathode that emits high electrons for a long period of time by mixing and adding an alloy of Ni and reducing metal as the powder to the powder of an alkaline earth metals compound. CONSTITUTION:A heater 2 is provided at the inner part of a cathode sleeve 1 and a cathode substrate 3 is provided on one end of the sleeve 1, then an alkaline earth metals compound layer 5 is provided on the substrate. A layer 4 in which an alkaline earth metals compound and the powder of an alloy consisting of Ni and Mg that is a kind of reducing metals are mixed is formed between the layers 5 and 3. As a result of this structure, since the reducing metal is contained in Ni as the alloy, the reducing metal becomes difficult to be oxidized. Consequently, even if this cathode is built in a cathode-ray tube, a fault of electron emission characteristics can not fully be seen. In other words, since the reducing metal is not oxidized in an intermediate process, the reducing metal reacts to the alkaline earth metals compound and the electron emission characteristics can be improved.

Abstract: PURPOSE:To speed up shape measurement processing by providing a photographing device, a means which predicts the quantity of light emitted by the light emission body, a photographic condition determining means, a photographing device control means, and a means which converts an image into a binary signal based upon a specific level. CONSTITUTION:The light quantity predicting means predicts the quantity of the light emitted by the light emission body 1 within the photographic range of the photographing device 2 and the photographic condition determining means 13 determines the photographic conditions (shutter, etc.) of the device 2 so that the body 1 appearing in the image photographed by the device 2 has specific brightness. Then the photographing device control means 3 controls the device 2 according to the photographic conditions determined by the means 13 to photograph the image 1. Then the brightness of the body in the obtained image is adjusted to specific brightness irrelevantly to the ratio of the body in the field angle, so the binary coding level of the binary coding means 16 which converts the image into the binary signal can be set to the constant value (e.g. 80% of specific brightness), so the logic of the means 16 is simplified and the whole processing is speeded up.

Abstract: PURPOSE: To obtain a pulse signal corresponding to bar code by using a threshold level which has a long space part of bar code and changes the level successively even in case of level fluctuation.  
     CONSTITUTION: The beam from laser 1 is caused to scan on bar code label 3 by rotary mirror 2, and the reflection light of lable 3 is received by light receiving part 4 and is amplified by amplifier circuit 5 and is subjected to envelope detection by envelope detector circuit 12. Simultaneously, the laser beam is directly detected by the second light receiving part 13 through mirror 2, and level conversion circuit 14 converts signal levels successively on a basis of detection signals from light receiving part 13. Since correct signals cannot be obtained correspondingly to bar code even if the output of circufit 12 is defined as the threshold level of lable 3 at a swelled bar code scanning time, etc., the output signal of circuit 14 is added to the output signal of circuit 12 in adder circuit 15 for the purpose of obtaining a good following for the signal change of label 3. The output signal of circuit 15 is waveform-shaped as the threshold level of label 3 by wave-form shaping circuit 16.

IPC: B60L50/10
Filed: 1990-01-26
Abstract: PURPOSE:To save onboard fuel by operating an engine generator fully at the time of traveling whereas obtaining power, to be consumed onboard, through a current collector in a section where feeder rail is laid. CONSTITUTION:When a train approaches a station and enters into a section where feeder rail is laid, a voltage detector 3 detects power supply through a current collector 2 and provides a signal to an ON delay circuit 8. The ON delay circuit 8 provides the signal, as a deceleration signal, to an engine r.p.m. controller 10 upon elapse of prescribed delay time thus throttling the generator output. Power to be supplied through the current collector 2 increases as the generator output decreases thus catering for the load power. Consequently, the engine generator is rendered no-load and performs idling thus saving fuel.
