Title: Radar for searching underground buried body
Inventor: KIMURA NORIAKI
IPC: G01S7/02
Filed: 1990-06-29
Abstract: PURPOSE:To detect a buried body regardless of its buried direction with the title device where planes of polarization of radio waves transmitted and received change every moment by transmitting and receiving radio waves, selecting in order two among the three antennas turned by 120 degrees. CONSTITUTION:A rotary encoder 11 provided a wheel with generates a distance pulse with running of the device. This distance pulse is supplied to a radar controller 12, the period is detected and three pulses for polarization change is generated in order between the period. These pulses are supplied to a polarization change circuit 16, and the circuit 16 selects in order two antennas among antennas 1 to 3, one for receiving and the other for transmitting. The controller 12 controls a transmitting circuit 13 and transmits radio waves at the fixed time for the change pulses to be generated. A receiving circuit 14 is controlled and operated only at the fixed time concurrently with transmitting radio waves. Thus, reflections from all directions can be received and detected, even the buried body of any buried direction because the polarization of transmission rotates 120 degrees apart and the polarization of receiving also rotates with the phase difference of 120 degrees against it.

Title: Injection molding apparatus
Inventor: OBARA MITSUHIRO
IPC: B29C33/72
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To automatically clean molds with high efficiency and improve productivity by providing on a stationary mold-side of a take-out device a cleaning body for cleaning the parting face of the stationary mold when separated from the movable mold, along with the inserting and departing motions of the device with respect to the gap between the stationary mold and the movable mode. SOLUTION: In molding, produced resin gas condenses and deposits on the mold. Such residue is likely to occur on the parting faces 12a, 14a of a stationary mold 12 and a movable mold 14, particularly around the gas vents. When an arm 32 of a take-out device 31 enters and leaves the gap between the molds 12, 14 in vertical motions, a brush 41 disposed on the arm 32 wipes and cleans the parting face 12a of the stationary mold 12. The brush 41 wipes an abutting surface of the parting surface 12a that abuts against the movable mold 14, but does not wipe the product molding face 12b. However, no problem arises since it is unlikely that gas condensation will deposit on the product molding face 12b.  Then, air supplied to an air passage is blown out of an air outlet toward the gas vents, to blow dust, such as resin residue, off the parting face 12a of the stationary mold 12, thus removing dust.

Abstract: PROBLEM TO BE SOLVED: To keep a conveying amount of a stencil base sheet at plate-making constant, to reduce an elongation or contraction of an image to be formed and to perform plate-making with a desired image by controlling a drive means so as to rotatably drive a platen roller by the drive means at a calculated driving speed. SOLUTION: A platen roller is rotatably driven at a set speed (ST1), an image is output to a thermal head (ST2), and an image is thermally perforated at a stencil bas sheet. Then, a conveying amount of the sheet in the case of rotating the roller is detected (ST3), a detected amount is compared with a pulse amount (reference conveying amount) of set data, and a displacement is calculated (ST4). If the displacement is not '0' (No in ST5), a difference due to the displacement is corrected at the present driving speed data, and next time driving speed data of the roller is calculated (ST6). On the other hand, if the calculated displacement is '0' (Yes in ST5), the present driving speed data is stored as next time driving speed data as it is.

Abstract: PURPOSE:To reproducibly and uniformly obtain the subject longitudinal semiconductor superlattice by alternately supplying raw material gases respectively containing an element constituting a semiconductor crystal layer to a base plate for growth. CONSTITUTION:A respectively prescribed amount of trimethylgallium and trimethylaluminium are initially alternately supplied onto a GaAs base plate 11 in order and Al and Ga atom planes are grown on a terrace 11a of the base plate crystal surface in the lateral direction to the step. Arsine (AsH3) is then supplied thereto to grow GaAs:15 and AlAs:14. According to the above- mentioned method, AlAs and GaAs are grown in order and a longitudinal superlattice is formed. As a single atom layer growth method where raw materials are alternately supplied is used in the above-mentioned method, deposition of Al on the next terrace can entirely be prevented in growth of GaAs on the remaining terrace part without requirement of accurate control of the growth conditions such as the supply of trimethylgallium, the growth pressure and the growth temperature. An ideal longitudinal superlattice can be formed therefor.

Abstract: PURPOSE:To suppress the amplitude of a weight while keeping the vibration isolating effect to a building to some extent by using an oil damper which becomes velocity square proportional type when damping force characteristic exceeds a certain velocity. CONSTITUTION:Between a weight 1 put on a set floor 2 through a static pressure bearing or roll 3 and the set floor 2, two links 4 are mounted through a universal joint 5 and a pin joint 6. Further, a reaction wall 7 built and fixed on the set floor 2 is communicate with the links 4 through a spring 8 and an oil damper 9. The vibration of a building caused by a generally blowing wind of about 10-20 m is reduced, and living property is improved.

Namely, the amplitude of the weight is linearly increased up to about 12 cm building amplitude, and is about 60 cm at the building amplitude of about 12 cm. When the building amplitude exceeds this, the ratio of weight amplitude/building amplitude starts reducing, and at about 100 cm building amplitude, the weight amplitude is suppressed to about 160 cm.

Filed: 1989-07-03
Abstract: PURPOSE:To obtain both a large deflection angle and high speed by manufacturing plural waveguides which differ in equivalent refractive index on the same substrate and selecting a waveguide where light is made incident by using an optical switch. CONSTITUTION:The waveguide substrate 100 is varied in equivalent refractive index by varying the widths of the waveguides 181 - 183 between 1 and 2mum. The beam emitted by a laser 10 is converged by a lens 20 and made incident on a waveguide 110 on the substrate 100 in TE mode and light projected from the waveguide 110 is confined to a Ti-diffused area on the surface of the substrate 100 and diverged in two-dimensionally, and converted by a waveguide lens 120 into a parallel beam, which is diffracted with a surface acoustic wave generated by an electrode 140. The diffracted light is converged by a waveguide lens 170 and coupled with an end surface of one of the waveguides 181 - 183. Thus, large variation in the angle of polarization mode conversion radiation from the waveguide with the equivalent refractive index is utilized to obtain a large deflection angle and there is no mechanical operation part, so the high speed operation is attained substantially.
