Title: Method and apparatus for measuring surface of cavity in inspection of brinell hardness
Inventor: NAKADA HIROHISA
IPC: G01N3/06
Filed: 1987-04-06
Abstract: PURPOSE:To obtain a highly accurate result, by applying a light absorbable substance different in light absorptivity according to a thickness. CONSTITUTION:When a light absorbable substance 33 is applied to a measuring surface 3, a sump part 39 is formed to a cavity 4 and a membrane 40 is formed on a flat surface. Next, when light is allowed to irradiate the surface 3 from the ring illuminator 16 mounted to the outer peripheral part of the head part 9a of an image pickup device, since the substance 33 is different in light absorptivity according to a thickness, the image of the surface 3 picked up by the image sensing device results in that the cavity part 4 is looked to be darker than the other part and can be clearly distinguished from the other part. By operating the surface area of the cavity 4 from the number of the picture elements of the region appearing to be dark by the image pickup device by a computer, hardness HB is calculated. As the substance 33, a sol like substance markedly changing in absorptivity and having viscosity generating no surface tension and not solidified is desirable and, from a practical aspect, lubricant for a machine is optimum. By this method, since the cavity part is clearly calculated, a highly accurate result can be obtained.

Title: Connector of driven form plate
Inventor: SUZUKI TAKESHI
IPC: E04B2/86
Filed: 1994-03-30
Abstract: PURPOSE:To prevent a displacement by shock by hooking the concrete contact side ribs on the reverse surfaces of adjacent driven form plates left after driving, and connecting the adjacent driven forms through an elastic member by an elastic plate connecting jig. CONSTITUTION:At connection, a swollen shell part is pushed by a finger, recessed and reversed to warp a connecting jig 2. The warped connecting jig 2 is pressed onto ribs 11, 11 on the reverse surfaces of placing form plates 1, 1. When the parts near the claw parts 21, 22 of the body of the connecting jig 2 is pushed, the warp of the connecting jig 2 is returned back, and the claw parts 21, 22 are hooked on the ribs 11, 11 to mutually connect the placing form plates 1, 1. The connecting jig 2 can be warped only by pressing the swollen shell part by the finger. The hook of the claw parts 21, 22 to the ribs 11, 11 is released to facilitate the removable. Thus, even when a shock is received at building, an elastic member 3 can act as a cushioning material to prevent the displacement or dropping-out.

Filed: 1993-04-12
Abstract: PURPOSE:To provide the powder coating machine constituted to enhance the probability of contact of a powder coating material with wall surfaces in terms of a passage shape in a triboelectrification region. CONSTITUTION:A powder flow passage 1 of the coating machine has a first expanding chamber 7 and second expanding chamber 11 which are both spherical in shape, successively from an upstream side to a downstream side. An intermediate passage 17 connecting this expanding chamber 7 and the second expanding chamber 11 is opened at a point where its inlet 17a and outlet 17b are largely apart from a common axial line L. The inlet port 9 of the first expanding chamber 7 and the outlet port 13 of the second expanding chamber 11 are both disposed along the common axial line L. The powder coating material flowing together with carrier air from the inlet port 9 into the first expanding chamber 7 collides against the wall surface of the chamber and much thereof bounces back toward the central part of the first expanding chamber 7. The material is then electrified while flowing in the first expanding chamber 7. The electrified material is admitted through the intermediate passage 17 into the second expanding chamber 11 and is fluidized similarly in the second expanding chamber 11; thereafter, the material is discharged through the outlet port 13.

Title: Magnetic bubble memory element and its production
Inventor: NISHIDA HIDEKI
IPC: G11C11/14
Filed: 1982-05-21
Abstract: PURPOSE:To obtain satisfactorily transmission characteristic in <=2mum range, by laminating successively a spacer layer, permalloy pattern layer, insulation layer, conductor pattern layer and passivation layer on a garnet film in order to reduce the distance between the garnet film and permalloy layer. CONSTITUTION:After forming a permalloy layer 5 over the whole surface of a spacer layer 2, a insulation layer 4 is formed, and its etching layer 5 and a conductor pattern layer 3 are simultaneously formed on the layer 2 close to a magnetic garnet film 1 so that the magnetic field effectively effects on the film 1. Also the pattern layer can be formed thicker due to the formation of electrodeposition. A polymeric resin is used for forming a passivation layer 6. Due to this constitution, the distance between the film 1 and layer 5 can be sufficiently reduced so that the layer can be made to be of planar construction. Since this element (Characteristics II) is made to be of perfect planar construction to set the distance between the film 1 and layer 5 to be the optimum, the equal transmission margin to a bubble having a larger diameter in comparison with conventional characteristics I , even if the diameter is <=2mu. In addition, a detection output never lowers, because the distance between the film 1 and layer 5 can be reduced.

Title: Pilot lamp circuit
Inventor: TAMURA TETSUMASA
IPC: H01L33/00
Filed: 1994-04-22
Abstract: PURPOSE:To prevent the dark illumination phenomenon of a light emitting diode from being caused when a multi-core cable becomes long. CONSTITUTION:When the multi-core cable 1 becomes long, coupling electrostatic capacity 5 is generated and a fine leak current is to flow to an LED 2B through the coupling electrostatic capacity 5 as shown by a dotted-line array although a contact point 3B OFF. A resistance 9B which has a resistance value less than the impedance value of the LED 2B is however connected to the LED 2b in parallel, so the majority of the leak current is bypassed through this resistance 9B. The compound resistance of the LED 2B and resistance 9B becomes less than that when only the LED 2B is used, so the voltage across the LED 2B becomes low. Therefore, even if the leak current flows to the LED 2B, the voltage across the LED 2B is lower than a working voltage and no dark illumination phenomenon is caused.

Title: Lock-up control device in automatic speed reduction gear
Inventor: TAKIZAWA SATORU
IPC: B60K20/00
Filed: 1985-04-23
Abstract: PURPOSE:To prevent an engine stall, by detecting the surface condition of a road so that the lock-up operation of an automatic speed reduction gear is inhibited when the frictional coefficient of the road surface is low. CONSTITUTION:A road surface frictional coefficient discriminating means 104 discriminates the frictional coefficient of a road surface in accordance with the result of detection by a road surface condition detecting means 103 for directly or indirectly detecting the surface condition of a road. A lock-up operation inhibiting means 105 inhibits the lock-up operation of a lock-up type torque converter 101 when the road surface frictional coefficient discriminating means 104 determines that the frictional coefficient of the road surface is less than a predetermined value. Therefore, even if any wheel-lock occures when a rapid brake operation is exerted in a low road surface frictional coefficient condition, it is possible to prevent the braking force of an engine from being effected, thereby it is possible to prevent an engine stall.

Filed: 1982-05-20
Abstract: PURPOSE:To obtain a corrosion-resistant alloy with high saturation magnetic flux density, high magnetic permeability and enhanced acid resistance, by adding small amounts of Ti and Zr to an Fe-Si-Al alloy and by regulating the amount of S among the impurities in the alloy. CONSTITUTION:This corrosion-resistant alloy with high saturation magnetic flux density and high magnetic permeability consists of, by weight, 4-12% Si, 3-8% Al, 0.1-1.0% Ti, 0.01-1.0% Zr and the balance essentially Fe or further contains 0.02-0.5% Ru. The amount of S remaining in the alloy is regulated to 3-30ppm. Ti and Zr are added to passivate the alloy surface. Since the alloy contains reduced amounts of S and sulfide which form rusting spots when the alloy is exposed to an oxidizing atmosphere for a long time, pitting corrosion can be prevented. The alloy has superior acid resistance and high magnetic flux density, so it is suitable for use as the material of the core of a magnetic head.
