Over an initial interval GI, gun barrel 1 turns with a horizontal posture, and thereafter, it commences tilting movement, which is controlled by the shape of tilting cum 11 fixed to a supporting rest. Tilting  lever 10 presses always sliding contactor 12 to cum 11 owing to the weight of gun  barrel 1. The radius of cum 11 grows from R 0  to R 1  when turning further about 10° from position 1, and as sliding contactor 12 moves in the direction of arrow mark K, lever 10 also turns, gun barrel 1 being moved as tilted. Further, from immediately before to after the tilting movement is completed (over an interval MN), a straight movement mechanism furnished moves gun barrel 1 straight toward a tap hole F.

Title: Digital-analogue converter
Inventor: YOSHIMURA KUNIHIKO
IPC: H03M1/66
Filed: 1979-04-26
Abstract: PURPOSE:To make it possible to form a high-resolution D/A converter easily by using two capacitors of the same capacity and an integrating circuit. CONSTITUTION:Electric charge of capacitor C1 is divided into two equally by connecting capacitor C1 in parallel to capacitor C2 of the same capacity, and this connection is cut again. All electric charge divided into two is transferred to capacitor C3 by differential amplifier 20 which is subjected to feedback by capacitor C3. If this operation is repeated n-number times, Q/2n of electric charge is transferred at the n-th operation. Consequently, when a control circuit is provided which supplies a digital signal through switch SW1 or SW2 and controls respective switches, Vout which was subjected to D/A conversion can be obtained. Since error of linearity of this D/A converter is dependent upon only capacitors C1 and C2, resolution can be improved by matching of capacities of two capacitors.

Title: Electronic watthour meter
Inventor: TAKAGI TOSHIO
IPC: G01R23/20
Filed: 1988-03-04
Abstract: PURPOSE:To accurately measure the reactive electric energy of even a system to be measured which generates higher harmonics by providing a couple of phase shifting circuits generating a relative phase difference which is substantially equal to 90 deg. in a prescribed frequency band. CONSTITUTION:A voltage signal and a current signal are sampled and held by sample and hold circuits 1 and 2 at a prescribed clock period and converted by A/D converters 3 and 4 into digital signals, which are sent to a multiplier 5 and phase shifting circuits 7 and 8. The output signal of the multiplier 5 corresponds to the product of the voltage signal and current signal and is integrated by an integrating circuit 9 to obtain data indicating active electric energy. The circuits 7 and 8 are a couple of entire-band passing type circuits whose phase difference is approximated to 90 deg. with prescribed band width. Thus, the digitized voltage signal and current signal are passed through the circuits 7 and 8 to generate the relative phase difference which is substantially equal to 90 deg. as to not only the basic wave components of both signals, but also even higher harmonic components; and the output signals of the circuits 7 and 8 are multiplied by a multiplier 6 and integrated by an integration circuit 10 to obtain reactive power data.

Title: Projector
Inventor: ABE KORESUKE
IPC: G03B21/28
Filed: 1980-04-19
Abstract: PURPOSE:To make a projector small-size and make formed images sharper by providing one or plural pieces of reflecting mirrors and an extra thin semitransparent  mirror in the optical path for the rays guided to a screen surface through a projecting lens, thereby reducing the optical path length. CONSTITUTION:The rays past a projecting lens 13 are reflected by a reflecting mirror 16, and about half the rays thereof pass through an extra thin semitransparent mirror 17, thence they are reflected by a reflecting mirror 18, and further about half these beams are reflected by the mirror 17 and are irradiated onto the surface of a screen 14, whereby they are imaged. Since the fixed optical path length can be put in a small space by causing the transmission and reflection of light and allowing the light to reciprocate in this way, the projector is made smaller in size and lighter in weight; in addition, double imaging is obviated and the formed images are made sharper by forming the semitransparent mirror extremely thin.

Title: X-ray high voltage device
Inventor: KOBAYASHI HIROMASA
IPC: H05G1/32
Filed: 1991-03-18
Abstract: PURPOSE:To obtain uniform output by setting a signal frequency to operate a converter to twice as much of frequency to operate an inverter, and equalizing peaks of X-ray tube voltage to each other. CONSTITUTION:A chopper operation clock CK is divided in two by a divider 15 and a divided signal CK2, as a result of division in two, is taken in a controller 14. Inverter operating signals ID2, and ID20, consisting of a period T2, twice as much as the period T1, of a chopper operating signal CD2, are created by the controller 14 by using the divided signal CK2. Furthermore, when the inverter operation signal ID2 is taken in the bases of TR1 and TR2 and the inverter operation signal ID20 is taken in the bases of TR3 and TR4 from the controller 14, a.c. voltage can be obtained on the primary side of a high voltage transformer 7. This a.c. voltage is boosted by the high voltage transformer 7 and rectified by a rectifying circuit 8, to obtain an X-ray tube voltage XP2. Ripple wave forms generated from a converter and an inverter are thus equalized to each other.

Title: Microlens
Inventor: AKIYAMA SHOICHI
IPC: G02B3/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a microlens having a structure which can improve resolution without decreasing the quantity of transmitted light even for a minute high- precision microlens having <10 μm diameter. SOLUTION: This microlens is provided with a phase shift region 6 disposed in a region overlapping with or near a refractive face 3 which causes a predetermined optical phase difference in a part of a light beam of wavelength λ transmitting through this region so as to interfere the diffracted light produced by the refractive face 3. Thus, the light beam transmitting through the phase shift region 6 is made to interfere with the diffracted light through the refractive face 3 so as to decease the intensity of the diffracted light. Thereby, since the spot size of the condensed light is not increased by the diffracted light and a region which cuts the light transmitted through the refractive face 3 is not present, only the intensity of the diffracted light through the refractive face which causes decrease in the resolution can be effectively decreased by the phase shift region 6 without decreasing the quantity of light.

Title: Heat exchanger
Inventor: FUJIOKA MASATO
IPC: F28F13/08
Filed: 1981-04-09
Abstract: PURPOSE:To improve the efficiency of heat transfer by fitting a plural stage of air-permeable solid walls onto the outer circumference of a heat exchanging tube in the multitubular heat exchanger. CONSTITUTION:The air-permeable solid walls 3 having air permeability and heat-resisting property are disposed rectangularly on the outer circumferences of the heat exchanging tubes 2. In this constitution, hot gas supplied from a hot gas supply port 5 is stopped and filled once at the upper stream sides of the solid walls 3 owing to the pressure loss of the air-permeable solid walls 3, is changed into an uniform current and passes through the air-permeable solid walls 3. When the hot gas passes, on the other hand, the potential heat of the hot gas moves instantaneously to the solid walls 3 because the air-permeable solid walls 3 have large convection thermal conductance, and surface temperature at the upper stream sides of the solid walls 3 rises instantaneously. Accordingly, the heat of the hot gas is directly transmitted to the heat exchanging tubes 2 while heat transmission through heat radiation transfer from the air- permeable solid walls 3 is added. Consequently, thermal conductivity can be improved properly setting the arrangement of the solid walls 3.
