Title: Operating speed control of actuator
Inventor: SATOU YASUHIKO
IPC: F15B11/04
Filed: 1979-04-28
Abstract: PURPOSE: To enable an actuator to operate at a stabilized speed by interposing a check valve between the actuator and the first change-over valve with a connecting portion between the actuator and the check valve being connected to a fixed volume cylinder through the second change-over valve.  
     CONSTITUTION: A check valve 12 is interposed between an actuator 10 and the first change-over valve 6, and a communicating passage 13 between the actuator 10 and the check valve 12 is connected to a fixed volume cylinder 18 through the second change-over valve 16. If the second change-over valve 16 is changed over after a fixed interval of time, a fixed volume of liquid is intermittently flowed out from a return liquid chamber B of the actuator 10 so that a piston 11 is intermittently moved at a constant speed until liquid is completely discharged from the return liquid chamber B. Thus, the actuator can always operate at a stabilized speed irrespective of pressure and temperature of liquid which is introduced into the actuator.

Title: Fuel feed control device
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/12
Filed: 1986-03-10
Abstract: PURPOSE:To smooth out change in torque accompanied with cut-off of fuel by judging whether or not engine torque is required based on not only information of deceleration but also the quantity of suction air at the time of regular deceleration whereby starting cut-off of fuel. CONSTITUTION:It is designed that while an engine is being decelerated, cut-off of fuel is not started even if engine speed N is greater than a predetermined engine speed Nc, at which point cut-off of fuel is started, as far as the quantity of suction sir is equal to a predetermined value or more, and cut-off of fuel will never be started before the quantity of suction air will become less than a predetermined value. Accordingly, cut-off of fuel is not effected when the quantity of suction air is great and when torque is still require by the engine, however, cut-off of fuel is started at the time when the demand for torque will become sufficiently small. As a result, the step difference in torque is prevented whereby change in torque can be smoothed out when fuel is cut off so as to improve operability.

Title: Correction lens for forming cathode-ray tube fluorescent screen pattern and metal mold thereof
Inventor: O HIDEO
IPC: H01J9/227
Filed: 1993-03-15
Abstract: PURPOSE:To form a fluorescent film for providing a high resolution cathode-ray tube, at high accuracy by matching the reference line of a plurality of planar or curved surfaces formed on the surfaces of metal mold materials, for which the same metal mold is used, with the lowest end of a tilted surface. CONSTITUTION:As the material forming a correction lens 2, optical plastic such as polymethyl methacrylate having high light transmittance, is used. The device is not regulated by the length of one side of planar or curved surfaces 2b, in which tilting in directions (x), (y) differs in relation to a reference surface 2c, while the reference line of the planar or curved surfaces matches with the lowest end of the tilted surface. Since the metal mold for forming the lens 2 is formed by using a metal mold formed on the surface of metal molds, for which several planar or curved surfaces are of the same number, the device is not regulated by the length of one side of the surface 2b. The lens 2 of high accuracy is thus provided. An extra-fine fluorescent surface can be formed by reducing the width of the lattice-shape bright/dark lines of a non-continuous boundary part largely affecting the exposure effect for forming dots.

Title: Detecting device for abnormal condition of wheel
Inventor: TASHIRO SOZABURO
IPC: G08B21/00
Filed: 1985-03-18
Abstract: PURPOSE:To enable an abnormal condition of wheels such as a flat tire to be easily detected by configurating a device in such a way that the degree of variability in revolving speed of wheels is compared one another so as to determine a wheel which shows the abnormal variability for giving a warning. CONSTITUTION:In a vehicle with numbers of wheels, a revolving speed sensor M1 is arranged to each of wheels to detect change in the revolving speed of each of wheels. Signals detected by these sensors M1 are inputted into a transducer M2 so as to convert them into arithmatical signals which are used to compute the degree of variability in the revolving speed of each of wheels. If any abnormal condition has happened to tire pressure because of a flat tire and the like, the degree of variability in the revolving speed of the tire appears to be excessively different from the rest of wheels. Accordingly, an arithmatic processing means M3 computes the degree of variability in revolving speed of each of wheels so as to compare it with each. And based on the resultant of the comparison, a warning means M4 is activated notifying that the abnormal condition has happened to a wheel.

Title: Method for coloring and sorting mineral
Inventor: SAKAI NORIO
IPC: G01N33/24
Filed: 1990-03-06
Abstract: PURPOSE:To make improvement in sorting accuracy by coloring granular mineral resources which vary in the degree of coloration to dyeing and in which >=2 kinds of minerals coexist by a dye and sorting the minerals by utilizing color differences. CONSTITUTION:For example, original ore is crushed and classified to <=20mm grain size. This ore is washed with water and dried. Feldspar and quartz are sufficiently separated when the original ore of the feldspar is unified to about <=20mm grain size. The feldspar maintains the colored state but the dye of the quartz is dislodged by the washing with water and the original color thereof is restored when the ore is immersed for a short period of time into a dye soln., such as 0.25% methylene blue soln., and is then washed with water. A color difference is the generated between both. Consequently the feldspar and the quartz are easily identified. If aprite (resin-granite) contg. the small particles of the feldspar and the quartz coexists in the original ore of the feldspar, the aprite has many cracks on its surface and well absorbs the dye so as to exhibit the color much darker than the color of the feldspar and, therefore, the sorting of the feldspar and the aprite is possible as well.

Abstract: PURPOSE:To enhance the efficiency of light utilization by a method wherein a reflection film is provided on the second main surface of a semiconductor substrate whereon a light receiving part and a transfer part are formed on the first main surface. CONSTITUTION:The light receiving part is formed by adhering a Schottky picture element electrode 2 of Pt of Au as the material on the first main surface 1b of the P type semiconductor substrate 1, and the reflection film 20 e.g. of Al which functions as a light reflection means is adhered on the side of the second main surface 1a of the substrate 1 whereon the transfer part is formed by adhering a transfer electrode 7. When an incident light a comes into the substrate from the side of the first main surface 1b, this light causes photoelectric conversion by striking onto the Schottky picture element electrode 2. The remnant light transmitting through the electrode 2 advances into the substrate 1 and is reflected on the reflection film 20, and causes photoelectric conversion by being incident again into the Schottky picture element electrode 2. Then the light coming into the part except for the light receiving part is also reflected on the reflection film 20 and thus introduced into the Schottky picture element electrode 2.

IPC: C22F1/04
Filed: 1991-03-19
Abstract: PURPOSE:To improve the surface precision of aluminum alloy stock by mirror- like finishing, at the time of subjecting Al alloy stock to mirror-like finishing, by regulating the average value of the grain size on the surface of the stock to specified value or below. CONSTITUTION:The average value of the grain size on the surface S to be subjected to mirror-like finishing in Al alloy stock 1 for mirror-like finishing is regulated to <=50mu. When the above surface S is subjected to mirror-like finishing by buffing or the like, the depth L2 at the recessed part 4b on the inside part of the crystalline grains 2 (grain size D2) reduces compared to the depth L. at the recessed part 4a in the case of large grain size D1. In this way, mirror-like finishing can securely be executed without the formation of deep recesses on the surface S at the inside of the crystals.
