Abstract: PURPOSE:To develop a sliding member which is softer than an opposite member to be slid and has a recessed part for retaining lubricating oil and is excellent in abrasion resistance by performing hard plating on the surface of the sliding member in a mechinery and thereafter projecting heat rays having high-density energy while acting assistant gas pressure. CONSTITUTION:After forming a hard Cr plated layer 2 having 50mum thickness on the surface of a base material 1 for the sliding member of a mechinery, it is regulated to definite thickness by grinding work. Successively while acting 1.0kg/cm<2> assistant gas pressure by gaseous N2 or the like of the surface of this hard plated layer 2, spotty laser beams 5 controlled in required heat energy are converged by a lens and projected thereon and many dimple-type recessed parts 11 having 10-20% porosity are formed. Softened layers 2a which are softer than the opposite material to be slid are formed in the peripheral parts and the bottoms of the repressed parts 11. Therefore the opposite member to be slid is not scratched and abraded by the edge parts of the recessed parts 11 nd also lubricating oil is retained therein and thereby the sliding member excellent in abrasion resistance is manufactured.

Title: Demodulated data check system
Inventor: HOSHINO EIICHI
IPC: G06K7/00
Filed: 1981-06-25
Abstract: PURPOSE:To read surely normal demodulated data, by comparing demodulated data, which is inputted plural times, with every data different in value successively and outputting coincident data when the repeat number reaches a certain value. CONSTITUTION:The first demodulated data is stored in the first buffer 3, and the first gate circuit 2 is turned off. Second and third gates 2' and 2'' are turned off first. The second demodulated data is compared with the first demodulated data in the first comparing circuit 4. If they coincide with each other, output ''1'' is sent to the first coincidence number counting circuit 5. The thrid and following demodulated data are operated similarly. If, for example, the third demodulated data is not coincident, ''0'' is outputted and is inverted to ''1'' by an inverter 8-0, and a controlling circuit 6 turns on the second gate 2'. Thus, the third demodulated data is stored in the second buffer 3'. Under this state, if the fourth demodulated data is coincident, 1 is added to the count value. The similar operation is repeated hereafter; and when any counted value reaches a certain value, data of a corresponding buffer 3 is outputted through an OR circuit 9.

Abstract: PURPOSE:To prevent the reduction of adhesion between graphite powders by soaking an artificial graphite powder in the mixing solution of an undiluted sulfuric acid and an undiluted nitric acid, and making the volume dilatation of the produced compound when it is heated rapidly up to a high temperature, less than 5 times of the original volume. CONSTITUTION:An artificial graphite used for a negative electrode is formed by making carbonized needle coke as a filler, and mixing a pitch to it as a binder, and then it is made into a graphite by heating. The graphite powder is soaked in a mixing solution of an undiluted sulfuric acid and an undiluted nitric acid, so as to make a compound between graphite layers including sulfuric acid. And the volume dilatation when the compound is heated rapidly up to a high temperature is made less than 5 times of the original volume. Furthermore, the artificial graphite is crushed, and a binder of an acrylic resin, and a water solution of carboxymethylcellulose are added to make into a paste. The paste is applied to both sides of a specific thickness of copper foil, and dried to form a specific size of negative electrode. As a result, the reduction of the adhesion between graphite powders is prevented, the collecting efficiency is improved, and the charge and discharge property is also improved.

Filed: 1979-08-02
Abstract: PURPOSE:To form a vapor deposition film having desired characteristic for regulating the temp. of the substrate not to exceed a desired temp., by providing a reflection plate in the passage of infrared rays between the substrate and bell jar in the vapor deposition apparatus. CONSTITUTION:A reflextion mirror 4 is provided between a transparent substrate 2 and a bell jar 5 on occasion of performing vapor deposition of transparent film on the transparent substrate 2 made of glass etc. which is attached to the substrate holder 3 in the vapor deposition apparatus. As a result, the substrate 2 is heated by the infrared rays from the evaporation source 1, and the direction of a part of the infrared rays passed through the substrate 2 is changed by the mirror 4. Accordingly, temperature rise of the substrate 2 is prevented, and vapor deposited film having desired characteristic is formed because the substrate 2 is not heated again by the infrared rays since the rays are not reflected by the wall of the bell jar after passing through the substrate 2. It is more effective to jointly use cooling method, such as with water.

CONSTITUTION:A cleaner main body 11 is provided with a leak valve 55 which introduces fresh air into an electric blower 21 as when a paper pag filter 32 clogs up. The leak valve 55 is comprised of a circular leak hole 62 for taking fresh air into the electric blower 21 from the suction side of the blower, a valve body 57 provided on the electric blower 21 side of the leak hole 63 and adapted to open and close the leak valve 63 by making its spherical abutting face 73 abut on and leave the seal portion of the leak hole 63, and a spring body 58 which normally brings the valve body 57 into sealing contact with the inner edge opening 64 of the leak hole 63. As a result, the burning of the electric blower caused when the dust collecting filter clogs up and the thermal deformation of the cleaner main body can be prevented and lowering of the suction power of the cleaner during normal cleaning operation can also be prevented.

Abstract: PURPOSE:To prevent a double thread from being rolled in when rewinding is resumed after two threads which are to be connected together have been connected, by fixing a part of a thread guide 1 which has branched off from a seam, apart from a regular thread guide which continues inclusive of the seam. CONSTITUTION:When it is detected 8 that a thread Y1 being rewound from a bobbin B to a package P has been cut or the bobbin B has been emptied, a drum 9 stops. A relay pipe 10 and a suction mouth 11 suck a thread end from chain line positions 10a, 11a and turn and move, and threads YB, YP on the bobbin B side and package P side intersect and are connected at a thread connecting device 12 and it is led to the outer part of the device 12 and stops. After the suction mouth 11 has operated, within a predetermined time until the relay pipe 10 operates, the thread YP is led to a guide near the detection device 8 and inserted into a groove, and after a seam has been checked by the detection device 8, the thread YB is sucked into the relay pipe 10. Next, rewinding is resumed by a drum 9 and the package P. As a result, the double rolling in of the thread is prevented.

Title: Electromagnetic valve
Inventor: TAKAHASHI MOTOHIRO
IPC: F16K31/06
Filed: 1978-08-16
Abstract: PURPOSE: To control the flow and pressure with an electromagnetic valve normally by guiding the valve body on preventing the lean of valve in opening or closing the passage with the valve.  
     CONSTITUTION: The guide rod 20 is fixed to the valve proper 1 so that the rod coincides with the axial center of the long hole 19 provided to the plunger 7 of the valve body 6. When the valve opens or closes the passage between the valve body 6 and the valve seat 5, the guide rod matches with the long hole and prevents the lean of valve body. Since the up-down movements of the valve body that opens and closes the passage 4 is performed in the axial direction of the magnetic material 10 which repulses to the electromagnet 12, the lean of valve body is prevented to control the flow normally, an electromagnetic valve with a good control characteristic can be obtained.
