Inventor: MIYAZAWA TAKENORI
IPC: B82B1/00
Filed: 1992-02-07
Abstract: PURPOSE: To obtain a contact-type sensor by which the flaw, of a product, which is hard to optically detect such as a flaw in a same color, a black flaw, etc., can be detected automatically without generating a blind spot by a method wherein a comb tooth-shaped probe which has been bent in the middle is brought into contact with an object, to be inspected, so as to be scanned and the strain, of the probe, which is generated by the unevenness of a surface is detected by a piezoelectric element. CONSTITUTION: As a comb tooth-shaped line probe, a line probe which has been bent in the middle is used so as not to generate a blind spot when it comes into contact with a product. A silicon thin film 9 which has been doped with phosphorus and continuity patterns 10, 11 are formed on the root part of the line probe by a vapor growth method, a piezoelectric element is formed, and a line sensor 50 is formed. The line sensor 50 is fixed by a holding utensil 51 in such a way that the contact angle 37 of the center line of the tip of the sensor with the face of the product becomes, e.g. 80 deg. or higher. Then, products 53c, 53b, 53a are conveyed by a conveyor 54, they are brought into contact with the line sensor 50, a signal from the tip of the probe is amplified ADD-converted and image-processed and the flaw of the products is detected automatically.

Title: Automatic development processor
Inventor: KATSUTA TAKESHI
IPC: G03D3/06
Filed: 1985-03-19
Abstract: PURPOSE:To obtain an automatic development processor provided with a small- sized and compact supply device which has a simple structure and supplies efficiently a processing liquid to each processing tank and is less faulty, by providing the supply device which supplies a certain quantity of the processing liquid on the processing tank where the processing liquid is stored. CONSTITUTION:When the elapse of a prescribed time is measured, a processing liquid supply signal is issued to drive a liquid quantitative supply device, for example, 23, and an eccentric shaft, for example, 27 is turned downward, and a quantitative object 26 is immersed in a developer D in a developer vessel 21. Since the liquid surface of the developer vessel 21 coincides already with the aperture of an overflow tube 21A, the developer of the same volume as the quantitative object 26 is overflowed from the overflow tube 21A and is supplied directly into a developing tank 2 under the tube 21A. When the quantitative object 26 is pulled up after a certain quantity of the developer is supplied into the developing tank 2, the developer in the vessel 21 is reduced by the volume of the quantitative object 26 and the liquid level falls, tube the developer is flowed out from the tank 22 through an aperture 22A and the liquid level is restored to the height to close the aperture 22A.

Abstract: PURPOSE:To drill a hole through reinforcing fibers without causing burrs by providing a cutting part on a tip wall part of a tool body, and providing curved cutting edge extending along a cylindrical curved surface around an axis and advancing in the direction of rotation toward the base end side. CONSTITUTION:A flat part 2 is formed on a tip of a tool body 1, a tip face of an tool tip la of theremaining side wall part is shaped into a flat face S tilted at an angle alpha to an axis O, and on the outer peripheral edge part a cutting edge 4 tilted at an angle beta to a plane including the axis O when viewed from II direction, is provided. When a hole is drilled, a part around a tip point P of the cutting edge 4 shears a material to be cut along the contour of first bitten hole of the material, and reinforcing fibers are cut together with synthetic resin as if they were cut by a knife. When the tool body 1 is advanced while it forms the contour of the hole, a portion forming the inside of the hole is brought into contact with the flat face 3, scratched by the flat face, and collapsed to becomes chips, and thus no burrs,etc., are produced on the edge and the outer periphery of the hole. Since the rate of back taper is formed to be 0.4mm-2mm per 100mm, and the reinforcing fibers are not caught on the outer peripheral surface of the tool body 1, frictional resistance can be reduced, and the cutting accuracy and surface finish of the hole can be improved.

Title: Detection circuit
Inventor: NAKANISHI HIDEKAZU
IPC: H04B1/04
Filed: 1990-03-08
Abstract: PURPOSE:To improve the linearity of a detection output by adopting a variable resistor for a load resistor. CONSTITUTION:A control signal S50 applied from a power control section 50 in response to a control power level is used to allow a switch 33b to switch a fixed resistor 33a, thereby varying a load resistance. The dynamic range of a detection voltage with respect to the input power is expanded by >=10dB through switching of the load resistor. Since the switch 33b and a voltage divider are switched interlockingly by the signal S50, the power control is attained over a wide dynamic range. The load resistance of 100ohms is selected in the case of a high input power level and a load resistance of 5Kohms is selected at a low input power level to obtain a detection output with excellent linearity.

IPC: H01H3/42
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To stabilize the switching operation of a device by forming a projecting part in the direction binding the movement of a roller engaging with a lever in the peripheral part of the lever. SOLUTION: A switching operation is stably performed by forming a projecting part 50 in the peripheral part of a lever 14 to regulate the engagement position of a roller 18 and thereby imposing a predetermined load on a breaking latch 16. In a closing operation, while a closing cam 1 is pushing up a main lever 11, the peripheral part of the lever 14 abuts on the roller 18, the roller 18 is hit at the moment it comes into overrun and vibrates on the engagement surface of the breaking latch 16, but the vibration range is immediately regulated by the projecting part 50 formed in the peripheral part of the lever 14. The overrun of the lever 14 is terminated after the main lever 11 exceeds its upper dead point, and the lever 14 is engaged with the breaking latch 16 through the roller 18.  The roller 18 is engaged at a proper position, a predetermined action load is transmitted from the lever 14 to the breaking latch 16, and the torque required for a breaking coil is set constant, so that the stable switching operation can be realized.

IPC: F16H55/22
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent deformation of a tooth part, guarantee smooth engagement and prevent abnormal noise and torque fluctuation. SOLUTION: A raised part 11b having curvature the same as or larger than curvature of an outside diameter of a worm gear 12 and a ring thick part 11c are integrally formed on a tooth part 11a of a worm wheel 11 on a motor with the worm gear engaged with the worm gear.
