Title: Self-traveling working machine
Inventor: YAMAKAWA TAKAYUKI
IPC: E02F9/24
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To enhance safety by checking whether or not the reflected wave exists generated by an ultrasonic wave generation means, by determining whether or not the surface of the ground exists, and lowering the optical axis of a working lamp downward if the surface of the ground does not exist ahead. SOLUTION: When the engine of a hydraulic shovel 1 is started, an ultrasonic wave sensor 11 starts to operate, transmitting transmitted waves toward the surface of the ground that is always at a fixed distance ahead and receiving the reflected waves. Then a working lamp 9 is turned on to initiate traveling action or a digging operation on bad roads or in mountainous areas, etc. Then if no reflected waves are read from the ultrasonic wave sensor 11 although a fixed period of time has elapsed, a controller determines whether or not the reflected waves are received. When determining that no waves are received, the controller determines that the hydraulic shovel 1 is approaching the top of a slope.  The controller further drives a working-lamp drive mechanism 10 to set the optical axis of the working lamp 90 to a downward position L where it is lowered by θ1 from a normal position N, thus lowering the reflection range of light by the working lamp 9.

Title: Production of saturated hydrocarbon
Inventor: NAKANO MUNETOSHI
IPC: C07C5/03
Filed: 1989-11-11
Abstract: PURPOSE:To obtain a saturated hydrocarbon in high efficiency and at a low cost by purifying 5C fraction containing diolefin and monoolefin and halides as impurities with water or alkali water at high temperature under high pressure and then hydrogenating the saturated hydrocarbon in the presence of a catalyst. CONSTITUTION:5C fraction containing diolefin and monoolefin and halides (e.g. 1,3-pentadiene and cyclopentene) and halides as impurities is purified with water or alkali water (e.g. aqueous solution of NaOH) at 100-200 deg.C under 7-30atm. for 30 seconds to 30 minutes to remove the halides and then hydrogenated in the presence of a catalyst such as Pd or Pt at 40-200 deg.C under 5-40atm. to give a saturated hydrocarbon. Preremoval of the halides suppresses deterioration of hydrogenating catalyst and can prolong life of the catalyst. A residue which is obtained by subjecting a hydrocarbon mixture prepared by naphtha cracking to cationic polymerization and removing most of diolefins as a polymer is used as the 5C fraction of raw material.

Filed: 1989-11-10
Abstract: PURPOSE: To reduce a thrusting danger caused by a cannula by the constitution that a piston in a case body exists between the both coupling portions, and is slidably arranged toward a vertical axis direction at between an extended position and a retracted position, and the scarf end of a cannula is safely sealed into the case body when the case body is sufficiently long and the piston is in the retracted position. CONSTITUTION: A needle is drawn out from an injected position after injecting an agent contained in an injector by pushing an inner cylinder from the retracted position to the extended position. The retraction of an injection needle is carried out by moving a pin 60 while holding the case body at a fixed position, or by moving the outer cylinder 38 of the injector toward the right direction and then sliding the piston 22 to the retracted position. The pin 60 is locked in response to a lock means used. Accordingly the needle is drawn out, simultaneously sealed into the case body, followingly the piston 22 may be slidden to the retracted position from the extended position. In this case, the scarf end of the cannula 50 is fully sealed into the case body. For caution's sake, a plug 78 is inserted into the bore 20 of an end wall of the closed end of the case body.

Filed: 1987-11-21
Abstract: PURPOSE:To make it possible to form an extruded piece having annular part with very small degree of sectional ununiformity, even when the crosssectional area of a core is small, by a method wherein a bridge is arranged neat the inlet of a slit part. CONSTITUTION:A mold 2 has a die ring 21 with a resin introductory part (a) and a core 23, which is connected through a bridge 22 to the die ring 21. Further, a slit part (b), which finally straightens and shapes synthetic resin to the desired annular shape, is provided between the final parallel part 211 of the die ring 21 and the core 23 so as to be connected to the resin introductory part (a). The bridge 22 is provided near the inlet of the communicating hole to the resin introductory part (a) of the slit part (b).

Abstract: PURPOSE:To reduce the deterioration of a picture by applying compression deciding coefficient of an equation of higher degree so that a data string representing graduation is made nearly coincident with values on a curve represented by the equation of higher degree and applying expansion calculating the coefficients and gradation values from the equation of higher degree representing the curve. CONSTITUTION:Values representing gradation of a picture element 24 at the end of a picture element string 12 and values representing the gradation of the picture element 25 at the end of a picture element string 13 are regarded as values of an element next to the picture element 24 and the picture element strings 12, 13 are treated as data strings representing a series of gradation. Then the coordinate and gradation data of the picture elements on the picture element string 31 are expressed by four values of coefficients A-D of a cubic equation. Thus, the values representing the gradation of a picture are expressed by 4 coefficients A-D. Thus, the picture data is compressed so that the value calculated by an equation of N=4/(number of picture elements of a picture) equal to the compression rate N, where 4 is the number of coefficients in a cubic equation.

IPC: G11B21/21
Filed: 1993-11-25
Abstract: PURPOSE:To perform stable information recording by forming the structure provided with slit-like grooves on the sliding surface of a slider against a disk. CONSTITUTION:The sliding surface 51 is arranged with a base in the planar shape over the whole surface, and the slit-like grooves 61 are formed thereon. When taking notice to the pressure distribution on the relative surface between the sliding surface 51 of the slider 11 and the surface of a disk medium, the pressure generated on this part is a contact pressure and a pneumatic pressure between solid materials, and the amounts of them are inversely proportional to the distance between the relative surfaces, then the pressure is high on the part of the sliding surface 51 and low on the part of the grooves 61. So, the foreign materials such as worn particle, etc., are instantly moved to the grooves 61 from the sliding surface 51. By this constitution, the increase of the distance between the disk medium and magnetic head slider caused by depositions such as the worn particle, etc., and the decrease of a recording magnetic field on the disk as well are suppressed, therefore, the stable information is recorded on the disk.
