Title: Fluidized catalytic cracking method of heavy petroleum
Inventor: USHIO MASARU
IPC: C10G11/18
Filed: 1980-12-30
Abstract: PURPOSE: To improve the conversion of heavy petroleum in the fluidized bed catalytic cracking, by feeding catalytic particles flowing through a fluidized catalytic cracking apparatus partially to a high gradient magnetic separator, and removing the metal in the heavy oil as magnetized catalytic particles.  
     CONSTITUTION: Catalytic cracking particles, having a particle diameter of 5W 200μ, and flowing through a fluidized catalytic cracking apparatus having the respective zones of reaction, separation and stripping are partially taken out and fed to a high gradient magnetic separator containing net-like packings, having a wire diameter of 10W1,000μ and a size of 3W80 mesh, and made of a ferromagnetic material placed on top of each other in a space of a high magnetic field by a transferring gas, e.g. air, at a particle concentration of 0.01W500g/l and a transferring fluid speed of 0.01W100m/sec. The catalytic particles are separated into a magnetized catalytic particles magnetized by the deposition of a metal, e.g. nickel, contained in a heavy petroleum and unmagnetized catalytic particles, which are then returned to the cracking apparatus. The fluidized bed catalytic cracking of the heavy oil is carried out while reusing the returned catalytic particles.

Title: Engine speed controlling apparatus
Inventor: HARA KAZUO
IPC: F02D35/00
Filed: 1980-12-27
Abstract: PURPOSE: To prevent unnecessary operation of an actuator or the like of an engine speed controlling apparatus and to improve durability of the apparatus, by employing such an arrangement that a setting value of the vehicle speed, one of the conditions for controlling the idling operation, is varied according to the control conditions.  
     CONSTITUTION: A carburetor 3 is mounted on an intake manifold 2 of an engine 1. A contact signal 9 from an actuator 8 that is disposed on the side face of the carburetor 3 for opening and closing a throttle valve is applied to a control circuit 10. An ignition pulse 11 produced by an ignition coil 5 that is connected to the ignition plug 6 via a high-tension code 7 is also applied to the control circuit 10, and a control output 12 of the circuit 10 is affored to the actuator 8, thus completing a closed loop control. With such an arrangement, a setting value of the vehicle speed for starting control on the idling operation is selected to be low at the time of starting the vehicle but high at the time of stopping the vehicle, whereby it is enabled to prevent repetitive operation of the actuator 8 at the time of controlling the idleing operation.

Title: Power unit for vehicle
Inventor: MATSUSHIMA SEIYA
IPC: H02J7/35
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To improve the working efficiency of a power unit for vehicle by making the discrepancy of the voltage of a battery between the time, when the voltage becomes the rated voltage of the battery and another time when the electric power from the battery becomes a peak correctable by making the voltage, when the electric power from the battery becomes the peak, to be equal to the rated voltage by bringing the open-terminal voltage of a solar cell device nearer to the rated voltage by adjusting the number of solar cells of the solar cell device. SOLUTION: The power peak of a solar battery device 3 is roughly adjusted to the rated voltage 12 V of a battery 1 by reducing the number of solar cells 2 to 8 (from 12 in the conventional example) and the bringing the opening-terminal voltage of the device 3 closer to the rated voltage of the battery 1 by adjusting the voltage to 17 V (from 23 V in the conventional example). When the voltage of the battery 1 becomes higher (for example, 17 V) than the rated voltage 12 V, therefore the device 3 exhibits effects what can be characterized as being a self-regulator, because the voltage does not reach 17 V and the charging current is suppressed to '0' or close to it. In addition, the working efficiency of the device 3 can be extremely improved, because the working range and power peak of the device 3 substantially match with each other.

Title: Impeller for blower
Inventor: SATO SEIJI
IPC: F04D29/38
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To improve fan efficiency and reduce noise by reducing leak vortex at vane outer peripheral end portion of a blower impeller. SOLUTION: This impeller for blower has blades 11, 11 larger in chord length toward outer peripheral portions 11e, 11e and front edges 11a, 11a thereof being advanced in blade rotation direction. Near rear edges thereof, the blade outer peripheral portions 11e, 11e are smoothly curved toward negative pressure surfaces 11d, 11d. Further, the impeller is constructed such that a distance from a fan center O on the inner peripheral surface of curved portions P, P is longer in the reverse direction of fan rotation. Such construction prevents growth of vortex because leak vortex generated at the outer peripheral portions 11e, 11e of the blades 11, 11 hit against inner peripheral surface of the curved portions P, P.  Accordingly, aerodynamic noise is reduced and the circumferential component of force acting on the inner peripheral surface by the collision becomes the rotational force, resulting in an improved fan efficiency.

Title: Manufacture of board holder
Inventor: SAKUMA SHIGERU
IPC: H05K13/04
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To support a board stably by setting the fixing position of a supporting pin accurately while conforming to the component mounting face of intricate shape. SOLUTION: Irregular shape of a board mounting face mounting electronic devices is acquired as a three-dimensional data. The three-dimensional data is processed and sorted into a data indicative of the component area and a data indicative of the area on the board surface for each scanning line. The sorted data is presented on a plan view having an established coordinate system. When the areas on the board surface are consecutive on a single scanning line, for example, the consecutive coordinate points are connected with a line in order to obtain a plan view where the board surface area is discriminated definitely from the device area. Consequently, a supporting pin can be fixed to an optimal position on a board holder based on the plan view.

Title: Arc welding method
Inventor: MIYAWAKI MASAO
IPC: B23K9/028
Filed: 1982-10-27
Abstract: PURPOSE:To prevent the lack of penetration and melt-down of a thick material having a good heat conductivity by performing welding while oscillating mechanically or magnetically a preceding non-consumable electrode thereby dispersing the arc heat in a groove. CONSTITUTION:A preceding non-consumable electrode 2 is oscillated to disperse the arc heat to the side face of a groove as well whereby the heating area is widened and the concentration of the arc heat in the central part of the groove is prevented in the stage of performing arc welding while supplying alternately welding current to the electrode 2 and a consumable electrode 3. A defect-free weld zone having high quality is thus obtd. with a material such as copper or copper alloy of a thick plate.
