Abstract: PURPOSE:To convert a heavy hydrocarbon oil into a light hydrocarbon oil economically with a high yield, by adding a specified coking inhibitor to the heavy hydrocarbon oil and heating it under pressure in the presence of hydrogen. CONSTITUTION:A coking inhibitor consisting of fine particles which contains a compd. consisting of typical elements only (e.g. carbon black, alpha-alumina, white carbon or magnesia particles) and a transition metal or a transition metal- containing compd. (e.g. Fe, Co, Ni, V, T and oil-soluble compds., water-soluble compds. and oxides which contain these compds.) are added to a heavy hydrocarbon oil (e.g. residual oil of normal pressure or vacuum distillation) and the oil is treated at 380-550 deg.C under the pressure of 30-300kg/cm<2> for a dwell time of 1-120min in the presence of hydrogen. The heavy hydrocarbon oil is converted into a light hydrocarbon oil economically with a high yield.

IPC: G03G15/08
Filed: 1979-07-05
Abstract: PURPOSE: To prevent the developer from depositing on the inside surface of a conveying path and assure the stable circulation of the developer by discharging the charged charge of the developer moving in the circulatory transport path right after the development in a developing device which circulates the dry type developer of electrostatic latent images by carrying the same in air flow.  
     CONSTITUTION: The remainder of the dry type toner used in a developing chamber 2 for the purpose of developing of the electrostatic latent images on the surface of a dielectric drum 1 is carried together with air in a circulatory transport path 4 by the sucking force of a pump 5. Before the toner is separated from the air in a filter 6, an AC electric field is applied to the toner in a destaticization device 10 right after the development to neutralize the charged charge of the toner thereby preventing the toner from electrostatically depositing on the inside surface of the circulatory transport path 4. The destaticization device 10 consists of two opposing parallel electrode plates 11, 12 and is disposed in the pipe forming the circulatory transport path 4. AC voltage is applied from an AC power source 13 to the electrode plates 11, 12.

Title: Noise suppressor for solenoid brake
Inventor: MATSUMURA MITSUYOSHI
IPC: F16D65/18
Filed: 1989-04-05
Abstract: PURPOSE:To eliminate any resulting during rotation by installing a steel ball, being pressed by a spring, on a braking plane between a brake plate and a moving magnet core shiftably set up in the axial direction, rolling this ball, and improving its smoothability so better. CONSTITUTION:When voltage is impressed on a magnet coil 2, a moving magnet core 4 is attracted against pressing force of a braking spring 3 by dint of magnetic attraction. Accordingly, a rotary disk 6 so far pressed to a brake plate 7 comes free of rotation, and is rotated by turning effort of a turning shaft 9. When this impressed voltage is erased, the magnetic attraction goes out, and the core 4 is pressed to the brake plate 7 together with the rotary disk 6 by dint of pressing force of the braking spring 3, so that the rotary disk 6 and the turning shaft 9 both are braked. In suchlike constitution, when the turning shaft 9 is operated in the vertical direction, the rotary disk 6 tries to drop at both sides of the core 4 and brake plate 7 with its own weight. At this time, since a spring 10 makes the rotary disk 6 so as to be floated via a steel ball 11, its smoothability is improved by this steel ball 11, thus there are no rustling and abrasion is decreased.

Abstract: PROBLEM TO BE SOLVED: To prevent information on an erased old session from being mistakenly obtained in the case of a CD-RW disk, by accessing a lead-in area of a divided final session and obtaining lead-in information as valid information only when the information is judged to be valid. SOLUTION: A lead-in area of an innermost circumference of a CD-RW disk is accessed, and start time information on the area is obtained from ATIP information. PMA information is obtained on the basis of the start time information on the lead-in area. Adjacent tracks are divided to sessions on the basis of a time interval of the tracks by the PMA information. A lead-in area of a divided final session is accessed and, the presence/absence of lead-in information and its validity are judged. The judgment is conducted, for example, by any one comparative inspection of TOC information included in the lead-in information and PMA information or on the basis of a combination of a plurality of the inspections.

Title: Manufacture of thermal head
Inventor: MICHIHIRO TOSHIAKI
IPC: B41J2/335
Filed: 1990-03-31
Abstract: PURPOSE:To ensure that a head substrate can be electrically connected to a drive substrate using a connection conductor by constituting the head substrate and the drive substrate with materials of different thermal conductivity, melting and connecting an electrode of the substrate of a high thermal conductivity to the connection conductor, and then melting and connecting an electrode of the substrate of a low thermal conductivity to the connection conductor. CONSTITUTION:When a head substrate 3 is melted and connected to a drive substrate 4 using FPC 11, first the head substrate 3 is connected to FPC 11 and then a drive substrate 4 is connected to FPC 11. In addition, heat generated by a heater used on a connection part 16 is conducted to a connection part 12 side through connection wiring of FPC 11, when the drive substrate 4 and FPC 11 are connected together. However, the thermal conductivity of the head substrate 3 is set to be high so that the conducted heat rapidly spreads into the head substrate 3 from the connection part 12. The connection part 12 is prevented from reaching the level of temperature at which solder melts. Thus the generation of a faulty connection can be prevented.

Title: Logic valve
Inventor: MORIKAWA IWAO
IPC: F15B11/16
Filed: 1979-07-12
Abstract: PURPOSE: To reduce the closing time required to close a logic valve after the discharge rate of a variable displacement hydraulic pump is decreased to around zero "0", by using the logic valve, which performs the fluid connection or disconnection of a hydraulic circuit through the closing or opening of a poppet, in a closed hydraulic circuit for controlling the pump.  
     CONSTITUTION: A poppet 10, conduit 13 connected to an actuator, spring 16, shuttle valves 22, 23 and solenoid valve 21 are provided in a logic valve. When the solenoid valve 21 is at position A, the higher pressure between pressures of conduits 12, 13 acts on the rear face of the poppet 10 and the poppet is thus pushed down by the pressure and spring 16 so that the logic valve is closed. On the contrary, when the solenoid valve 21 is at position B, the lower pressure between the pressures of conduits 12, 13 acts on the rear face of the poppet 10. In such a manner, the logic valve may not be opened simultaneously with an opening of the solenoid valve, thus prohibiting their corresponding actuators to work suddenly.
