Title: Prevention for clogging of sprue
Inventor: SHIMAZAKI HAJIME
IPC: B22D18/04
Filed: 1981-09-22
Abstract: PURPOSE:To prevent clogging of a sprue in low pressure casting by providing a void part between a stalk and a heat insulating cover provided on the outside circumference thereof and insulating the heat of the molten metal. CONSTITUTION:Molten Al 2 is charged from a heat insulating furnace 1 into a sprue 11 of a bottom part 10 through a stalk 5 and a sub-riser 9 under low pressure, and is filled into product parts. When the stalk 5 and the sub-riser 9 cool quickly, the molten metal 2 returning to the furnace 1 through the sprue 11 then through the sub-riser 9 and the stalk 5 upon ending of the filling into product parts solidifies and clogs the sprue. However, air is forced through a pressurizing pipe 4 into the furnace 1 to maintain the metal 2 always at a constant height in the stalk 5. Since a hole 7 is provided in a void part 8 for heat insulation, the molten metal 2 does not rise. Since the temp. drop of the molten metal in the stalk 5 is prevented by the heat insulating effect of the air in the part 8, the clogging of the sprue is obviated.

Title: Shaped beam antenna
Inventor: KUSANO MITSUHIRO
IPC: H01Q19/12
Filed: 1982-08-27
Abstract: PURPOSE:To prevent a radio wave reflected from a main reflecting mirror from being shielded by a primary radiator, by arranging the center axis of a beam of the primary radiator in a plane bisecting vertically a line segment tying two foci of two torus mirror surfaces. CONSTITUTION:The main reflecting mirror is constituted by combining torus mirror surface reflecting mirrors 6, 8 and rotary reflecting parabola reflectors 7, 9. The reflecting mirrors 6, 7 use a point F1 as a focus and the reflecting mirrors 8, 9 use a point F2 as a focus, and the reflecting mirrors 6, 7 and 8, 9 constitute respectively one composite torus mirror surface. On the other hand, the primary radiator 10 is arranged so that the center axis of the irradiated beam is brought into the negative Z axis in the plane bisecting vertically the line segments F1, F2 tying the points F1 and F2. Thus, the reflected wave irradiated from the radiator 10 and reflected on the main reflecting mirror is not shielded for the path by the radiator 10 in this way. Then, the impedance characteristic is not deteriorated because of the reflected wave from the main reflecting mirror returned directly to the radiator 10, and the adverse effect of scattered waves due to the radiator 10 is prevented.

Title: Production of barium sulfide
Inventor: SHIOSAKI KEN
IPC: C01B17/44
Filed: 1987-06-16
Abstract: PURPOSE:To obtain barium sulfide in high yield from barium sulfate by reduction on heating barium sulfate powder in a hydrogen atmosphere at specified temperatures. CONSTITUTION:Barium sulfate powder is reduced while heating at 600-900 deg.C in a hydrogen atmosphere. For the reaction temperature, the reaction rate is too low at <600 deg.C; on the other hand, temperatures exceeding 900 deg.C are undesirable in terms of the material characteristics and economy. For the particle size of the barium sulfate powder, <=100mu (esp. <=50mu) is preferable for enhancing contact between the barium sulfate and hydrogen gas. Also, to help contact between these two substances, utilization of a fluidized bed reactor or various types of agitator will be effective. The resultant barium sulfide can readily be converted into various barium compound such as barium chloride, barium carbonate, barium sulfate, etc., being also useful as a raw material for lithopone, barium ferrite, etc.

Title: Control method for the time when trouble is caused with differential-pressure sensor used in electronically controlled fuel supplying apparatus
Inventor: SAKURAI SHIGEO
IPC: F02D41/24
Filed: 1983-08-17
Abstract: PURPOSE:To enable to operate an engine in a stable manner to a certain extent, by substituting the output signal of a differential-pressure sensor by a predetermined output signal in a fuel supplying apparatus for controlling the air-fuel ratio in case that trouble is caused with the differential-pressure sensor. CONSTITUTION:A differential-pressure sensor detects the pressure difference on the opposite sides of a throttle valve. When it is detected that some trouble is caused with the differential-pressure sensor, a signal S0 corresponding to the output signal produced by the differential-pressure signal for a certain pressure difference is determined. Further, providing that the injector pulse width at the time of no-load operation of the engine is tau1(ms) and that at the time of medium-load operation of the engine is tau2, the air-fuel ratio is controlled on the basis of the signal S0 while restricting the quantity of fuel supplied per one stroke of the engine by controlling the injector pulse width tauP of a fuel injection means to satisfy the following relationship, tau1<tauP<tau2. By employing such a method, it is enabled to operate an engine in a stable manner to a certain extent even if trouble is caused with the differential-pressure sensor.

Title: Disturbing wave eliminating device
Inventor: HARA YASUHIKO
IPC: G01S7/36
Filed: 1989-06-13
Abstract: PURPOSE:To effectively eliminate disturbing wave component signals by compensating base band signals for the offset voltage. CONSTITUTION:A main channel signal S20 and an auxiliary channel signal S21 are divided and formed by a power divider 36 and a 90 deg. hybrid circuit 44, and two base band signals are generated by mixers 46a and 46b. In close (open) loop offset voltage compensating amplification part CLA1 and CLA2, amplified signals compensated for the offset voltage due to close (open) loops are integrated by integrators 56a and 56b to generate modulating signals S24a and S24b. Signals formed in a 90 deg. hybrid circuit 42 by the signal S21 are modulated in modulators 68a and 68b by these signals S24a and S24b and are synthesized by a power combiner 64. Then, disturbing wave component signals are subtracted from the signal S20 by a subtractor 32 and are eliminated. Thus, the close (open) loop following-up control to set the level of signals, which are supplied to be integrated by integrators 56a and 56b, to 0 is rationalized, and disturbing wave component signals are effectively suppressed.

Abstract: PURPOSE:To set the slant angle of a liquid crystal molecule optionally with improved reproducibility by vapor-depositing the 1st oxide on a substrate surface slantingly in a minus direction, and then the 2nd oxide whose ratio of an element bonded to oxygen to oxygen per coordination number is larger than that of the 1st oxide slantingly at right angles to said minus direction, and carrying out a slanting orientation treatment.
