Title: Comparator
Inventor: TAKEMURA YUTAKA
IPC: H03K5/08
Filed: 1982-05-31
Abstract: PURPOSE:To output directly a pulse from a comparator, by providing a diode repeating conduction/nonconduction periodically according to a difference between a potential of a voltage dividing point of a resistor from a DC power supply and a potential of an output pulse. CONSTITUTION:A potential Vs at a negative terminal 16 of a full-wave rectifier circuit 14 is a negative full-wave voltage. Further, a voltage of a DC power supply 2 is divided with resistors 3, 4 and a level of the potential at a connecting point 8 fed by the potential Vs is shifted positively with the divided voltage. When the potential at the connecting point 8 is higher than that at an output terminal 6, a diode 9 is made nonconductive, no current flows, and when the potential at the connecting point 8 is decreased by a junction voltage or over of the diode 9 less than the potential at the output terminal 6 according to the decrease in the full-wave voltage, the diode 9 is made conductive and a current flows. Since the potential VR is changed periodically, the output voltage is pulsed.

Title: Flow rate measuring method for powder
Inventor: MATSUSHITA ASUKA
IPC: G06T7/00
Filed: 1994-04-07
Abstract: PURPOSE:To measure the flow rate of powder highly accurately without bringing a detector into contact with powder by flowing the powder down through an inclining rotary drum rotating at a constant speed and picking the image of powder falling through the outlet of the drum by means of a TV camera. CONSTITUTION:Powder 5 filled in a hopper 1 is conveyed on a belt conveyor 2 and flowed clown through a feeder 3 and an inclining rotary drum 4 to a collecting position. When the rotational speed of the drum 4 is constant, the powder 5 flows down with a constant width W and thickness (h). A TV camera 6 is disposed at a position for monitoring the falling powder from the front side thereof while spaced apart by a predetermined distance therefrom. The image of powder 5 across the flow width W is picked up and processed 7 before being fed to a personal computer 8. The personal computer 8 storing the working curve of actual flow rate and the flow width W detects the flow rate of powder 5 immediately from the processed image and displays the flow rate. The working curve is prepared using the actual flow rate measured by means of a belt scale 9 and the flow width W determined from a processed image.

Title: Apparatus for molding automotive instrument panel
Inventor: MATSUNO YOSHIO
IPC: B29C45/00
Filed: 1986-04-23
Abstract: PURPOSE:To prevent a distortional deformation of resin along a weldline, by setting at least two pouring holes among numbers of pouring holes on the upper surface of about center part in the direction of the car width and symmetrically on right and left from the connecting part of an instrument panel tightly connecting with the car body. CONSTITUTION:When the molten resin is poured into a mold, a position of a weldline 18 formed by joining together a molten resin flowed from a pouring hole 12 in the direction of an arrow mark D and a molten resin flowed from a pouring hole 13 in the direction of an arrow mark E coincides with a connecting part 21 set at about central part in the direction of the car width. Therefore, when an instrument panel 11 is fixed on the car body by using clamping bolts 23, 24 and 25 after molding, the clamping bolt 24 is inserted and fixed on the same position as the line 18. Therefore, because the line 18 is tightly contacted on the car body by using the clamping bolt 24, occurrence of a distortion on the weldline 18 caused by a left stress can be prevented when the panel is exposed in a heating process. An instrument panel without wavy or convex-concave part on the upper surface of the panel 11 can thereby be obtained.

Title: Synthesizing method for cubic system single crystal of boron nitride
Inventor: DEGAWA JUNJI
IPC: B01J3/06
Filed: 1987-04-15
Abstract: PURPOSE:To synthesize large single crystals by mixing a substance having large solubility for boron nitride with boron nitride and adjusting the supply speed of the boron nitride under the condition of synthesizing a cubic-system single crystal of boron nitride. CONSTITUTION:Seed crystals of cBN are grown by using a mixture of raw material boron nitride supply source such as hexagonal crystal boron nitride (hBN) or the like and a substance (solvent) having a large solubility of boron nitride such as lithium strontium boron nitride (LiSrBN2) or the like by means of the solubility difference between hBN and cBN to the boron nitride generated by the temperature difference under the melting condition of high temperature and high pressure. In other words, cBN single crystals are grown only out of seed crystals 1 of comparatively low temperature because of the solubility difference between hBN and cBN boron nitride generated by the difference between the temperature of said mixture 6 and that of said seed crystals 1. When the seed crystals 1 are small, the temperature difference (DELTAT1) is reduced, and the crystal growth speed is slowed down, while as the crystals are grown up, the temperature difference (DELTAT2) is increased to enhance the crystal growth speed. By said arrangement, synthesizing of large single crystals can be achieved by a shorter period of time than the methods heretofore available.

Title: Small-sized two-stage optical isolator
Inventor: MAKIO RON
IPC: G02B27/28
Filed: 1989-04-13
Abstract: PURPOSE:To prevent reflection on an interface and to stabilize characteristics by arranging two Faraday rotators so that when light is made incident on the forward direction of the two-stage optical isolator, the light strikes on the surface of an LPE film first and then strikes on a substrate. CONSTITUTION:The Faraday rotators 1''a and 1''b and center polarizers 2b and 2c are fixed to a united center holder 5 and arranged so that the film surface of the LPE film is on the incidence side of the optical isolator. By this arrangement, reflected light from the interface is returned again through the Faraday rotators to enter the incidence-side polarizer, but the plane of polarization is rotated by 90 deg. through the Faraday rotators and almost all rays of the light is separated by the polarizers and does not return to the incidence side. Therefore, the reflection on the interface between the substrate and LPE film can be removed extremely efficiently.
