Abstract: PURPOSE:To position an optical axis accurately by determining the extent of driving of a mechanism having multi-numbers of degrees of freedom on a basis of the variation of the optical power from a fiber for driving of this mechanism to search the fiber position. CONSTITUTION:A laser diode chip 1 is fixed to a submount 2 and this submount 2 is fixed to a part 3. An optical fiber 4 is fixed through a hole of the central part of a column whose one end is fixed to the frame part 3, and the output terminal is led out to the external through a hole of the frame part 3. Since it is necessary to align the diode chip 1 and the optical axis of the optical fiber 4 with about 1mum precision, the column 5 is moved in X, Y, and thetadirections. The output of the diode chip 1 is detected by a detector 14, and a command value to the actuator of a mechanism 6 having multi-numbers of degrees of freedom (fine movement) is determined by a control circuit 15 on a basis of displacement just before movement and driving data due to displacement of the output, and this actuator is driven, thereby moving the column 5 for said alignment.

Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To enhance blood flow contrast from the slab inflow part to the slab outflow part of blood flow in the time-of-flight MR angiography of an MRI device. SOLUTION: In order to image fluid such as blood flow, an RF pulse with a shape such that for two regions separated from each other by an excitation profile in a slicing direction, a flip angle within the first region is constant while a flip angle in the second region gradually increases according to a predetermined function, is used as an RF pulse for selectively exciting image pickup regions. The use of such an RF pulse enables the amounts of signals to be maintained at the inflow side of blood flow, and at the outflow side of the blood flow a reduction in number of signals due to repeated excitation can be compensated and restrained by the increasing flip angle.

Abstract: PURPOSE:To prevent internal cracking and to prevent central segregation and the formation of center porosity at the lower rolling reduction by rolling down a billet in the end period of solidification and acting axially compressive force to the billet in a rolling down region. CONSTITUTION:The solid-liquid mixed part of the billet where a solidified part 1 and an unsolidified part 2 are mixed is rolled down by rolling down rolls 3 and the billet is fed by driving pinch rolls 4 on an upper stream side in the light reduction is the end period of solidification of the billet. The movement of the billet is braked by braking pinch rolls 4' on the down stream of the rolling down region by the rolls 3. More specifically, the moving speed lower than at least the moving speed of the billet by the pinch rolls 4 on the upper stream side is provided to the peripheral speed of the rolls 4', by which the compressive force is acted axially to the billet. The tensile stress of the billet generated by the rolling reduction of the rolls 3 is offset or relieved by such compressive force, by which the internal cracking owing to the rolling reduction is prevented.

Title: Aft circuit
Inventor: SAKAI YUJI
IPC: H04N5/50
Filed: 1986-06-05
Abstract: PURPOSE:To maintain a designated channel as it is even if the power supply is turned on at a time, for instance, when the broadcasting is not yet on air by providing a level discriminant circuit to discriminate the level of an intermediate frequency signal, and cutting off an AFT action at the time of no signal by using the output of the said discrimination. CONSTITUTION:An AGC voltage Vg is taken out from the AGC circuit of a sound intermediate frequency amplifier 4, and supplied to the base of a transistor Q1. The collector of a transistor Q2 is connected to the base of a transistor Q4 for switching via a transistor Q3, and the collector of the Q4 is connected to a circuit forming the AFT voltage Va for a video intermediate frequency amplifer 2. Accordingly, when the Q4 is ON, the AFT action is OFF. Since an AGC voltage Vg higher than a prescribed value can be obtained when there is a signal, the Q1 is ON, Q2 OFF, Q3 and Q4 also ON, hence the AFT voltage Va can be obtained and the AFT is executed. During a signal-lacking time, the AGC voltage Vg comes below a prescribed value, accordingly, the Q1 is OFF, Q2 ON, Q3 OFF, and Q4 ON, hence the AFT voltage Va is fixed at its middle voltage Vi, and the AFT is not executed.

Abstract: PURPOSE:To provide a video slot machine by which various games can be enjoyed by changing pseudo reels projected on a CRT screen. CONSTITUTION:A main reel 21 comprising a plurality of pseudo reels 6a to 6i and a sub reel 22 comprising two pseudo reels 23a and 23b are projected on a screen of a CRT 2 by a raster beam scan.

Abstract: PURPOSE:To obtain a carbon-containing refractory having improved oxidation resistance, spalling resistance, slag resistance and hot strength, by adding coarse particles of Al or Al alloy and boron nitride powder to a mixture of a carbonaceous raw material and a raw material of refractory. CONSTITUTION:100pts.wt. refractory consisting of 1-97wt.% carbonaceous raw material and 3-99wt.% raw material of refractory is blended with 1-30wt.% coarse particles having 0.5-20mm particle diameters, comprising one or more metals selected from aluminum and an alloy containing >=20wt.% aluminum and 0.1-10pts.wt. boron nitride powder to give a carbon-containing refractory. In the refractory, aluminum partially exists in texture of brick and parts having different coefficient of thermal expansion are scattered in the texture. Fine cracks are produced by the partial difference in thermal expansion, coefficient of thermal expansion of the whole brick is lessened to reduce mutually pressing force of adjoining bricks. Consequently, for example, even if the refractory is used as lining brick, release and wear are reduced and drop in life of furnace can be prevented.
