IPC: F02D9/02
Filed: 1989-07-17
Abstract: PURPOSE:To enable easy start-up suitable for a manual operation lever by applying the constitution wherein the operation point of a stepping motor is made to agree to the opening of a throttle valve for engine idling in setting initially the stepping motor connected to one end of a throttle valve spindle, and a throttle sensor is controlled with a manual operation handle. CONSTITUTION:In an engine like a fire engine, when a manual operation handle 14 for a fire-flow dial is operated and a throttle sensor 2 is made to operate via a wire 32 and a bent lever 33, a stepping motor 6 is driven with ECU 3 on the basis of output from the sensor 2, thereby controlling the opening of a throttle valve 4. The output shaft 7 of the stepping motor 6 is connected to one end of a throttle valve spindle 5 via a slip link mechanism 8, while a throttle drum 17 interlocked with an accelerator pedal P is fitted to the other end of the spindle 5. In this case, the operation point of the stepping motor 6 is made to agree to the opening of the throttle valve 4 for engine idling in setting initially the stepping motor 6, and the throttle sensor 2 is controlled with the manual operation handle 14.

Title: Distinction of crystalline form of single crystal
Inventor: KOUDA HIKARI
IPC: C30B29/10
Filed: 1989-07-14
Abstract: PURPOSE:To readily distinguish the crystal form of a single crystal by judging the form of a crystal to be beta-phase in case of presence of the central symmetry of the shape of the grown crystal without development of a specific plane when carrying out crystal growth of BaB2O4 single crystal having two kinds of crystalline form, i.e., alpha-phase and beta-phase by drawing thereof from a fused liquid using a high frequency furnace. CONSTITUTION:Development of a single crystal of barium borate (BaB2O4) having two kinds of crystalline form, i.e., alpha-phase and beta-phase, is carried out by drawing the single crystal from a fused liquid using a high frequency furnace. When the form of the grown crystal has the central symmetry without development of a specific plane, the form of the crystal is judged to be beta-form. By the above-mentioned method, the distinction of the grown crystal between alpha-BaB2O4 and beta-BaB2O4 can be carried out at the same time as growth of the single crystal. Accordingly, the suitable condition capable of stable growth of beta-BaB2O4 can be established in a short time, e.g. when the high frequency furnace used tor growth is changed.

IPC: B32B5/28
Filed: 1988-07-22
Abstract: PURPOSE:To obtain a molded product which has superior heat resistance, tenacity and shock resistance and which can suppress the spread of cracks at the shock, by forming said product by a fiber having a modulus of tensile elasticity within a specific range and attaching said product onto the surface of a thermosetting prepreg having reinforcing fibers specified in the range of weight as a base material or sandwiching said product between fiber reinforced resin laminations. CONSTITUTION:Such fiber is employed for the cloth that has the modulus of tensile elasticity not larger than 10,000kgf/mm<2>, preferably 5,000kgf/mm<2>. When the modulus of tensile elasticity exceeds 10,000kgf/mm<2>, the spread of cracks can be suppressed less effectively. Although the kind of the fiber is not restricted, particularly glass fiber or aromatic aramid fiber is suitable. The weight of the cloth is 21-25g/m<2>, preferably 5-10g/m<2>. If the weight is 25g/m<2> or more, the basic characteristic of the molded product is deteriorated. The reinforcing fiber is preferably a carbon fiber, glass fiber, aromatic polyamide fiber etc. having the ductility not smaller than 1.3%. Further, when it is applied to a composite that has the ductility not smaller than 4.0% after the composite employed for the prepreg is hardened, the composite becomes high in the level of shock resistance.

IPC: G01B11/24
Filed: 1994-08-04
Abstract: PURPOSE:To stabilize a Z-axis control system and measure at a high velocity with high accuracy when a three dimensional shape of an object to be measured is measured with the use of a non-contact displacement sensor. CONSTITUTION:At least two displacement sensors 4 and 5 are set to Z-axis 3 of a triaxial moving mechanism 10. While the sensors 4 and 5 are continuously scanned within X-Y plane on an object 20 to be measured, a distance in Z direction is measured for every measuring point set beforehand. Outputs of the displacement sensors are taken into a data-processing device 16, where an inclination of the object 20 is obtained. An optimum control condition for the Z axis is determined from the obtained inclination and a scanning speed. The height of the Z-axis is controlled to be constant under the optimum control condition. Z coordinate and, X and Y coordinates of the measuring point at the time are synchronously stored in a memory device 18, thereby, three dimensional shape of the object is calculated.

Title: Laser beam generator
Inventor: KANEDA YUJI
IPC: G02B27/28
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To suppress parasitic oscillation by reducing optical losses in a direction in which a fundamental wave enters while making optical losses in an optical resonator different depending on the direction of propagation of light. SOLUTION: A 1/2 wavelength plate 10 is disposed within an optical resonator, and at least one polarization-dependent optical loss is given inside the optical resonator. In a laser beam generator 1, the plate 10 and the polarization- dependent optical loss are combined whereby optical losses codirectional with a fundamental wave incident from a laser beam source 2 can be decreased and those counter-directional to the fundamental wave are increased. Since the optical resonator is provided with the directional loss in the laser beam generator thus constructed, parasitic oscillation in the counterpropagating mode can be prevented, and hence stable oscillation can be obtained.

Title: Flow velocity estimating device
Inventor: SAKAINO HIDETOMO
IPC: G01W1/10
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of moving speed estimation by obtaining the initial moving speed of each object between continuous time series images by image processing, and propagating the initial moving speed to each directional area by applying repetition of a moving average filter to predict the change of moving speed. SOLUTION: Time series images are inputted to an image input part 100 and stored in an image storage part 110. A moving speed detecting part 120 applies image processing to estimation of moving speed of an object and simultaneously obtains a moving vector 230 by a cross-correlation method, a moving vector 210 by a borderline displacement method, and a moving vector 200 by a center-of-gravity estimating method from an area with a large edge gradient. A recursive moving speed propagation part 130 sets three moving vectors as initial vectors and propagates the moving vectors to the whole image by a moving average filter for prediction, and an output part 140 outputs the predicted result. The moving vectors can therefore be extracted stably even in case of formation and disappearance of objects being considerable.

Title: Digital tape recorder
Inventor: TAGUCHI KATSUYUKI
IPC: G11B15/02
Filed: 1984-09-03
Abstract: PURPOSE:To realize a recording cancel function with high accuracy having no rest of erasing by controlling a running based on an address value recorded in an address rack on a tape and memorizing the address value at the time of a start of recording based upon a command. CONSTITUTION:A recording start command is fed to a CPU23, and then the CPU23 stores an address value x at that time in a memory 25, feeds a recording and running command to a mechanical driving portion 26 and a tape 21 begins to run at a recording mode. When a recording cancel command is fed to the CPU23, the tape 21 begins to rewind. At this time, by an address head 22, an address value is regenerated successively as (x+m), (x+m-1)... and fed to a calculating part 24 of the CPU22. In the calculating part 24, a present address value is compared with an address value (x) and a calculation is done and a command to lower the speed of the tape and the like are fed. When the address value (x) is regenerated, by the calculating part 24, a recording standby command is fed to the mechanical driving part 26 since the address value (x) coincides with the address value of a memory part 25 and a tape recorder has a recording standby mode.
