Title: Screw for molding machine, molding machine using the screw and method of transferring plasticized resin
Inventor: TAGUCHI MASARU
IPC: B29C48/67
Filed: 1988-07-11
Abstract: PURPOSE:To improve uniformity of resin temp. by providing a slit on the apex side of a screw on the screw for a molding machine. CONSTITUTION:A resin extruded from a metering section close to the apex of a screw 1 is divided into a resin flow having a drag flow extruded to the outer periphery side and another resin flow extruded from the metering section 3 to a slit 6 section and these resin flows and a resin flow having a width where the drag flow is not lost yet while it synchronizes with rotation of the screw 1 are joined and mixed each other by the rotation of the screw 1. There fore, the time for which the resin is brought into contact with a conical face of the screw 1 becomes very short to reduce generation of frictional heat and retention of the resin is prevented by joining and mixing of the resin flow each other. In addition, as heat generation and retention of the resin are prevented, occurrence of a part where the resin temp. is not uniform disappears.

Title: Control system of main memory device
Inventor: KUBO SHINICHI
IPC: G01R31/26
Filed: 1979-12-26
Abstract: PURPOSE: To prevent a 1-bit error from affecting a 2-bit error, by shifting all data of a faulty memory element to a substitute memory element when the prescribed fault is detected to an element which is usually used.  
     CONSTITUTION: When the prescribed fault is detected 13 to several memory elements of the main memory 5 which are usually used, the all data of the faulty memory elements are shifted to the substitute memory element 12. During this shift of the data, the original faulty memory element is used for reading of the data, while the same data is written to both the original faulty memory element and the substituted memory element 12. Then a control is given so as to read out the data of the element 12 after the data of the faulty memory element is shifted to the element 12.

Title: Direction change-over valve
Inventor: OBITANI YASUAKI
IPC: F16K11/07
Filed: 1981-10-28
Abstract: PURPOSE:To surely perform change-over of ports by providing a spool with pressure receiving faces to which a liquid pressure is applied when the ports are changed over. CONSTITUTION:When a pressure is reduced until a spool 12 is changed over to the oil discharge side, the interior of a hole 17 is communicated to an oil discharge port 11d to reduce the pressure. Then, the spool 12 is quickly shifted right by the force of a spring 14. When a pressure of the hydraulic oil which is supplied from oil supply ports 11a and 11b into a case 11 increases until the pressure exerted on pressure receiving faces 13a and 13b surpasses the force of the spring 14, the spool 12 starts to be shifted left. Once the oil supply port 11b is communicated to a groove 11e, namely, the interior of the hole 17, the spool 12 is quickly shifted to surely perform change-over of the ports.

Title: Method for measuring distance of gap
Inventor: NAGAI KOTARO
IPC: B23K9/127
Filed: 1993-07-13
Abstract: PURPOSE:To measure gap dimensions of welded places with high accuracy. CONSTITUTION:The gap dimensions of the welded places of an object to be measured where a projecting piece 11 and a cylindrical body 10 are welded together are measured by two optical sensors 1 and 2. The surface A of the projecting piece 11 and the surface B of the cylindrical body 10 of the object to be measured are irradiated with a laser beam and the two optical sensors 1 and 2 measure the distance to the surface part of the object to be measured. The change of the measured distance is investigated with the distance direction and the longitudinal direction for the object to be measured as a vertical axis Z and a horizontal axis X, respectively. The one optical sensor 1 measures the position X1 where the position changed by the specified distance in the vertical-axis direction from the surface A extending over to the surface B from the surface A and a changing graph of the measured surface cross each other and the other optical sensor 2 measures the position X3 of the ends of the face of weld of the surface B and the opposite side face in the same procedure from the surface B. The gap dimensions (g) are obtained from the expression, (g)=¦X3-(d)-X1¦ from the width dimensions (d) of the face of weld and the position X3.

Abstract: PURPOSE:To obtain the gallium arsenide single crystal which is low in oxygen content and high in purity. CONSTITUTION:Gallium (Ga) and arsenic (As) are charged respectively into a crucible 7 and an arsenic vessel 16 and a pump 4a is operated to evacuate the inside of an outer vessel 4 to a vacuum. Heaters 10a, 10b are operated to raise the temp. in the respective parts of the hermetic vessel 1 up to 200 to 600 deg.C. This temp. is maintained until the arsenic oxide in the arsenic vessel 16 and a vapor pressure control section 11 and the gallium oxide on the surface of the gallium raw material in the crucible 7 are removed to the outside of the hermetic vessel 1. A pushing up shaft 17 is then risen to press the seal 5 of the hermetic vessel 1 and to hermetically seal the hermetic vessel 1; thereafter, the single crystal is grown by the method similar to the conventional methods.

Title: Production of relief structure
Inventor: MORI YASUKI
IPC: G11B7/26
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To easily produce an optical disk or the like by dry development which can be easily duplicated, by heating a photosensitive layer to increase the film thickness of an exposed part and then uniformly exposing the whole surface of the photosensitive layer. SOLUTION: The photosensitive layer is formed on a substrate by laminating a photosensitive film on the substrate in such a manner that the photosensitive layer is in contact with the substrate. An optical system usually used for exposure for the pattern of an optical disk is used to expose the photosensitive layer to form the pattern. Then, the photosensitive layer is heated to increase the film thickness in the exposed part. Since monomers moving from the nonexposed part to the exposed part remain as unreacted, recording in the optical disk can be stopped by uniformly exposing the whole surface.

Title: Electromagnetic pump for driving hydraulic actuator
Inventor: KIRYU YUICHI
IPC: H02K44/00
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency and control stability by applying a magnetic field perpendicularly to the flow direction to a flow path for making a liquid conductor flow and at the same time energizing a pair of electrodes and hydrodynamically series-connecting each flow path so that each output direction of a conductive type electromagnetic pump unit accords. SOLUTION: An electrode 22a disposed above a lower conductor 22 and an electrode 22b disposed below an upper conductor 22 form a pair of electrodes. A flow path is connected to an adjacent unit by a connection flow path 21b which is formed in an insulating structure body 24 and bent in a U-shape. Since the directions of magnetic flux of adjacent units are opposite to each other and the drive force of an identical direction works in all driving flow paths and those are connected so as to be added in the flow paths, a large pressure is generated in the whole of the flow paths. The flow paths of two pump units are disposed on both sides of one conductor having the electrode of two parallel planes to collectively form a number of pump units, thereby being able to achieve miniaturization and light weight.

Title: Liquid crystal light valve
Inventor: SONEHARA TOMIO
IPC: G02F1/133
Filed: 1987-07-13
Abstract: PURPOSE:To obtain a high bright and dark light current ratio so as to assure on-off and to increase a production margin by using a liquid crystal layer having bistability and a photoconductor layer having a current rectifying property. CONSTITUTION:The bistable liquid crystal layer 101, a photoseparating mirror 102 and the photoconductor layer 103 having the current rectifying property are sandwiched by transparent substrates 105 provided with transparent conductive films 104 and non-reflection coatings 106 are formed on the outside of the transparent substrates. This current rectifying property is generally imparted by a junction and barrier and is derived from the prevention of carrier injection at the time of reverse biasing. The high dark resistance equiv. to the equiv. resistance of the liquid crystal is realized by the low dark current arising from the carrier blocking; in addition, the large bright and dark light current ratio is obtd. The change in the partial voltage of the liquid crystal layer which arises in accordance with the on-off of writing light is thereby increased more than the change in the partial voltage generated by an ordinary photoconductive effect.
