Title: Damper device of clutch for torque converter
Inventor: NISHIMURA SADANORI
IPC: F16H45/02
Filed: 1982-06-24
Abstract: PURPOSE:To enable the effective absorption of a change in a driving torque, by increasing or decreasing an internal pressure in an inside space between an input case and the rotor of a pump according to the amount of the torque, and by making thereby a clutch board easy to slide in a region wherein the driving torque is small. CONSTITUTION:When a clutch board 9 is pressed onto the side of an input case 4 and made to engage therewith in friction (clutch connection) under an internal pressure in an inside space 6 generated by a drain oil from an oil chamber 10 positioned between the clutch board 9 and the input case 4, the rotation of an input shaft 2 is transmitted to an output shaft 3 via the input case 4, the clutch board 9, and a coil spring 11 and a turbine rotor 7. In an apparatus described above, a communication hole 15 communicating the inside space 6 with the oil chamber 10 is formed in the clutch board 9, and this hole 15 is opened and closed by an opening-closing member 16. The opening-closing member 16 interlocks to operate for closure with the compression operation of the spring 11 accompanying the relative rotation of the turbine rotor 7 in the reverse direction to the clutch board 9, i.e. in the clockwise direction.

Title: Manufacture of orientated laminated lumber
Inventor: ANDO YUICHI
IPC: B27N3/14
Filed: 1985-05-20
Abstract: PURPOSE:To obtain the laminated lumber, high in orientation property, by a method wherein fibrous elements, obtained by collapsing a lumber, are orientated so as to arrange fibers in a given direction and are pressurized to form them into a desired configuration under adding adhesive agent. CONSTITUTION:When raw material is compressed at a stroke, the fibers are collapsed, therefore, the raw material should by compressed gradually. It is preferable to employ a roller press to produce the fibrous elements continuously, however, the raw material, having short length, is better to be processed by well-known press device in batch system. Next, the compressed lumber is passed through a pair of rollers 7, 7 formed with corrugations on the surface thereof. When the lumber is passed through such rollers, a multitude of fibers is spread toward widthwise direction and the fibrous elements 10 are produced. Subsequently, the fibrous elements 10 are pressurized under a condition that they are mixed with the adhesive agent to form them whereby the orientated laminated lumber may be completed.

IPC: G01C19/42
Filed: 1984-05-28
Abstract: PURPOSE:To detect correctly an inclined angle even during the shaking of a substance to be measured with a simple construction by providing two pieces of accelerometers at the prescribed intervals in the height direction in a floating body type light buoy. CONSTITUTION:A floating body type light buoy is constituted by sinking to the sea bottom with a sinker 1 and so as to float a light buoy 5 on the sea surface S with the float of a tower body 3 and float body 4. The tower body 3 is made an inclination possible by a universal joint 2. Two pieces of accelerometers are provided with the input axis in parallel at the interval of the prescribed distance and intersecting in right angles with the vertical axis of the tower body 3. An inclined angle is detected respectively by the 1st accelerometer and the 2nd accelerometer. Then a signal I multiplying the signal transmitted from the 1st accelerometer by the distance between the 2nd accelerometer and the universal joint 2 and similarly a signal II multiplying the signal transmitted from the 2nd accelerometer by the distance between the 1st accelerometer and joint 2 are found at the arithmetic part and the influence due to the shaking is eliminated by subtracting the signal II from signal I. Consequently the inclined angle can be detected with high accuracy even during the light buoy shaking.

Title: Color filter
Inventor: TSUKAMOTO TAKETO
IPC: G02B5/20
Filed: 1989-04-27
Abstract: PURPOSE:To suppress the discoloration of a phthalocyanine dye and to prevent the generation of unequal colors of reproduced video images by using the phthalocyanine dye as a dyeing material and adding an alkyl boron compd. thereto at a specific ratio of the resin component of the color filter. CONSTITUTION:The phthalocyanine dye is used as the dyeing material of the color filter formed by using an easy dyeable photosensitive resin and forming prescribed pattern layers, then dyeing the pattern layers by a dyeing method. In addition, the alkyl boron compd. is added thereto at <=1wt.% of the resin component of the color filter. There is the probability that the phthalocyanine dye receives a photoreduction reaction by external light and exists as a negative electron reductant in the resin matrix. A change in absorption spectra, i.e., the discoloration is probably caused by the formation of this reductant. The electron donative group in natural protein and the boron compd. are previously coordinated in order to prevent this discoloration. The lowering of the electron donative property thereof is possible in this way and the generation of the unequal colors is prevented.

Abstract: PURPOSE:To prevent the generation of air rich condition and carry out the efficient operation of a boiler, etc. by a method wherein the ratio of air to fuel is kept constantly most suitable by changing the change velocity of the change rate of a preset signal for the amount of fuel flow and a preset signal for the amount of air flow on the basis of the deviation signal between a signal for the amount of fuel flow and a signal for the amount of air flow at the time of load change. CONSTITUTION:When a deviation is generated between a signal 1 for the amount of fuel flow and a signal 4 for the amount of air flow at the time of load ascending, the difference is detected by a subtracter 12 and when a deviation signal 13 is larger than a specified value, a preset signal 10 for the amount of air flow passing through a restriction device 17 for the change rate of air is restricted in its change velocity by the rate of change preset by a function generator 16 at the air side, and thereby, a control damper 6 for the amount of air flow is controlled through an air controller 5. When the signal 13 is larger than the specified value at the time of load descending, a function generator 14 at the fuel side acts immediately and a preset signal 8 for the amount of fuel flow passing through a restriction device 15 for the change rate of fuel is restricted in its change velocity.

Filed: 1987-05-01
Abstract: PURPOSE:To enable free selection of pressing speed in a simple constitution and to improve accuracy of stopping position by counting interval of angle pulse signal outputted from the angle detector by the reference pulse generated from a reference pulse circuit. CONSTITUTION:The angle detector 15 outputs the angle pulse signal at every prescribed angle of a crank shaft and the interval of the pulse oscillation is in inverse proportion to rotating speed of the crank. Further, the reference pulse generating circuit 21 provides a qualtz oscillator, etc., and generates the pulse at the constant pulse interval and sufficiently short interval. A counter 16 counts the reference pulse signal between the angle pulse signals and the result is inputted into a speed computing element 17 and the pressing speed is operated at each time. In accordance with the operating result, a slipping angle corresponding to this operating result is accessed from a storage device 22 by a speed stopping position computing circuit 18 to find the stopping signal generating angle and input to a comparator 19. At the time of coinciding with the signal from the computing circuit 18, the signal is outputted to a stopping control circuit 20. The stopping signal is outputted before the time by slipping angle coinciding with the actual pressing speed, and can correspond to variation of the pressing speed.
