Title: Mold forming method at uniform packing density
Inventor: SATOU YOSHIO
IPC: B22C15/28
Filed: 1983-01-27
Abstract: PURPOSE:To increase the packing density of sand and to obtain a casting surface having good quality in the stage of packing the sand in a molding flask by sucking instantaneously a large volume of air at a high degree of vacuum. CONSTITUTION:The sand in a hopper 1 is dropped into a molding flask 6 and a squeezing flask 9. A large volume of air is instantaneously sucked from the air vent 8 of a pattern plate 7 toward a vacuum tank 16 side having a high degree of vacuum by a selector valve 14; at the same time, a vibrator 13 is operated. The sand in the flask 6 and the flask 9 is packed at a high density in the periphery of the plate 7 by the suction operation and the effect of the vibrator 13. The sand is squeezed by a squeezing plate 10 and a squeezing plate 5 moved above the molding flask, upon completion of the suction stage, by which a casting mold is formed. While the vibrator 13 is operated, a piston 12 is lowered to lower the plate 7 and to detach the same from the casting mold. The oscillating air discharged from the vibrator 13 is ejected in this stage from the vent 8 of the plate 7 to improve additionally the releasing property of the casting mold.

Title: Array antenna device
Inventor: SUZUKI TATSUHIKO
IPC: H01Q19/28
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To improve the reflection characteristic of an array antenna, which is fed by a radial waveguide by connecting excitation probes to a radiation conductor via a triplet line layer provided between a dielectric substrate and the radial waveguide. SOLUTION: RF signals inputted to a feeding probe 4 are transmitted through a radial waveguide 3 from its center to its outer side in cylindrical waves. An RF signal connected to an excitation probe 5 excites radiating conductors 2 from the triplet lines 9 of a triplet line layer 8 via vertical feeding lines 7. Since the excitation probes 5 are arranged, having dispersion, the RF signal radiated again from the excitation probe 5 by reflection is prevented from being made incident on the feeding probe 4 of the radial waveguide 3 with an equal phase. The phase difference of the RF signals due to the dispersion of the arrangement of the excitation probes 5 is adjusted by the triplet lines 9, and all the radiating conductors 2 are excited with an equal phase.

Title: Laser array junction using mirror having photon band structure
IPC: H01S5/22
Filed: 1993-01-29
Abstract: PURPOSE: To improve a far field image by selecting a spatial period in such a manner that a light of symmetrical single-phase mode from a laser is reflected with a fairly higher reflection factor compared with other modes by using a geometrical configuration, as a result of a photon band structure of a periodical grating. CONSTITUTION: A one-dimensional semiconductor diode laser array having a photon band gap end mirror 30 includes a periodical structure of a square rod 32, including a photon band gap mirror. In the case that a photon band gap mirror 32 of the same phase exists, an in-phase mode becomes the highest reflection mode, and an out-of-phase mode 44 becomes the highest transmission mode through the mirror 32. Reflection factors of other modes are in between them. Light 42 of the same phase is reflected in a cavity of a laser 36. The reflectivity of the same phase is almost 100%, and the reflectivities of other mades are low. A light 46 radiated from the opposite side of the laser 36 preferentially becomes a light of the same phase, and a far field image is thus generated.

Abstract: PURPOSE:To operate two optional I/O2 with an instruction of one channel to perform the tape copy or the like, by providing a means which processes a command word which is different from a channel command and designates a command and an I/O address independently. CONSTITUTION:Channel command words CCW0-CCW3 are set to a channel command word register group 6 through a memory mode register 3 and an operating circuit 4 with a latch register by a start operation controlling circuit 2. The word CCW3 is read out from the register group 6 through a various-state detecting circuit 7 to detect whether an I/O controlling command code CMC exists or not; and if this code exists, an I/O part is set to a multi-I/O register 8. A channel word CHW of an I/O is read out from a channel word memory 9 by this I/O part. The command operation of the I/O designated by the word CCW0 and the command operation of the I/O designated by the word CCW3 are executed, and thus, two optional I/O2 are operated by an instruction of one channel.

Title: Optical disk
Inventor: TAKAOKA TAKASHI
IPC: G11B7/0045
Filed: 1984-01-28
Abstract: PURPOSE:To record information without changing the form of a beam irradiating part by converting locally a recording layer of a double structure containing 2 types of thin films into a single layer with irradiation of a beam containing the information. CONSTITUTION:A recording layer 15 containing two types of thin films 13 and 14 having different complex index of refraction is formed on a transparent substrate 11. The reflection factor Ri of the layer 15 to be set before irradiation of a laser beam 16 having a level higher than the recording threshold value is decided by thicknessed d1 and d2 as well as Fresnel reflection coefficients r1-r3 obtained at the interface between films 13 and 14. These films 13 and 14 are dispersed mutually and converted into a single film 18 by irradiation of said laser beam. Thus the Fresnel reflection coefficient r3 disappears and a reflection factor Rr is newly obtained for recording. As a result, the information can be recorded without changing the form of the beam irradiating part.

Title: Semiconductor sealing method
Inventor: YOSHIZUMI FUMINARI
IPC: H01L21/56
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To enhance the moldability of low-viscosity sealing material under low injection pressure, by providing the screw of an injection molding machine with a reverse flow preventing mechanism. SOLUTION: Sealing material fed into a hopper stays in the front part of a cylinder 3 through the rotation of a screw 1. The amount of the sealing material stayed is controlled by the position to which the screw 1 is retreated, and the sealing material is returned along the groove of the screw 1 at the next shot. Depending on the amount of this back-flow, products may develop filling failure or sink mark due to short shot. To cope with this, the screw 1 of the injection molding machine is provided with a mechanism to prevent or reduce back flow.  Specifically, back flow is reduced by installing a barrier 5 in the groove of the screw 1 or installing a plunger at the tip 4 of the screw to prevent sealing material from being returned to the groove of the screw 1, immediately before the screw 1 advances farthest in the final stage of injection filing when the amount of back flow is maximized.

Filed: 1983-01-31
Abstract: PURPOSE:To enable automatic adjustment of the oscillating position and width of a mirror by disposing sensors at both ends of the scanning line on a recording surface and controlling a mirror driving circuit by the signals from the sensors. CONSTITUTION:Laser light generated from a laser device 24 is deflected by a galvanomirror 23, is condensed by an Ftheta lens 25 and is set on the scanning line on a recording surface 6. Sensors 31, 32 such as photodiodes are disposed in a position A where scanning starts and a positon B where the scanning ends. The bias and amplitude of a saw tooth wave driving a galvanomirror 23 are variably adjusted by the signals from the sensors 31, 32 by which laser light is so controlled as to scan the larger width if the scanning width thereof is narrower than the positions A, B. The need for manual adjustment is thus eliminated and the oscillating position and the width of laser light are automatically adjusted.
