Title: Insulating structure for spot gun electrode and its production
Inventor: SHIMOYAMA ISAO
IPC: B23K11/11
Filed: 1985-01-09
Abstract: PURPOSE:To prevent trouble even if the side face of the piston rod of a spot welding machine contacts with a work by coating the outside circumference of the piston rod body with a steel pipe and insulating electrically the steel pipe and the piston rod body by a thin film-like insulating material. CONSTITUTION:The piston rod body 3 and the steel pipe 6 are electrically insulated by thin film-like insulating material 7. The conduction of electricity and the shunt occurring therein do not arise and no trouble arises even if the steel pipe 6 on the outside circumference of the piston rod contacts with the work 4. Since the outside circumference of the piston rod is coated with the steel pipe 6, the piston rod wears hardly, has the higher strength to impact and contributes to an improvement in the durability of the spot gun.

Title: Waste water treatment apparatus
Inventor: MIZUKAWA KENJI
IPC: C02F3/06
Filed: 1980-01-11
Abstract: PURPOSE: To accelerate the oxidation and decomposition of the organic materials in waste water and considerably improve the waste water treatment effect by generating the reflux distributing uniformly over the entire area of stationary beds without using ordimary pumps and the like.  
     CONSTITUTION: Air diffusion pipes 8 are installed vertically, and nozzles 5 ejecting air from below are provided in the air diffusion pipes. Stationary beds 2 are disposed around the air diffusion pipes. With such apparatus, air is ejected from each nozzle 5 upward into each cylinder 8b from the inside of the sunction pipe 8a of each pipe 8 through air piping 4 by the operation of a blower 6. As a result, the air ascends vigorously by becoming bubbles within each pipe 8. By the generation of this ascending flow, the waste water existing in the lower part of the stationary bed assemblies 2 is sucked into the suction pipes 8a. On the other hand, the waste water flowing out from the upper part of each pipe 8 induces vibration in the waste water surface 1a and the counter flow thereof forms descending flow and descends within the stationary beds 2a around the pipes 8. Namely, reflux is generated in the waste water in the tank 1, and as a result, the activated sludge clutured in the stationary beds 2a and the waste water having thoroughly contacted the air in the ascending process make uniform contact.

Title: On-vehicle control device
Inventor: KOIKE TOMOAYA
IPC: F02P5/15
Filed: 1994-01-14
Abstract: PURPOSE:To start an internal combustion engine positively and prevent the engine from being stalled by wrong starter operation. CONSTITUTION:A starter signal STA from a starter switch 5 is taken in through an interface 17, and as signal course, it is directly connected to a port 15STA of B/U (back up)-RAM 15 not via CPU 11. The signal course is thus connection to a port 11STA of the CPU 11 via a resistor 22 and a diode 23. In CPU 11, when engine rotational frequency NE from a rotation angle sensor 7 exceeds a specific rotational frequency, the port 11STA becomes Lo and the diode 23 becomes ON. The starter signal STA flows to the diode 23, and does not reach to B/U-RAM 15. An internal combustion engine is positively started due to the starter signal being masked within the B/U-RAM 15 at the time of starting, and so it is not stalled even when the starter is operated by mistake at the time of idling or running.

Title: Rotary compressor
Inventor: SUGIYAMA MAKOTO
IPC: F04B39/02
Filed: 1980-01-14
Abstract: PURPOSE: To achieve lubrication and sealing by sucking a lubricant onto a bearing section from an oil sump under a negative pressure through a small hole between an annular groove located between a rotating shaft and the bearing and a central hole with passage of a high pressure refrigerant gas through the central hole of the rotating shaft.  
     CONSTITUTION: Annular grooves 15 and 16 are cut on the inner periphery of bearing sections 5 and 6 for a rotating shaft 4 so as to be communicated to a central hole 10 on the rotating shaft 4 through small holes 17 and 18. The pressure in the annular grooves 15 and 16 is negative due to an ejector effect of a high pressure refrigerant gas through small holes 17 and 18 when flowing forward through the central port 10 at a high rate from a cylinder 8 of a compressor. The negative pressure allows oil to be sucked from an oil sump 12 through small oil supply holes 13 and 14 between the outer and inner surfaces of a bearing located before and after the grooves 15 and 16 communicated thereto. This enables the lubrication in the bearing of the rotating shaft 4 and sealing between the cylinder 8 and a rotor 7.

Inventor: HARADA HAJIME
IPC: H02M3/28
Filed: 1987-01-09
Abstract: PURPOSE:To suppress output voltage build-up, by applying a feedback winding to a floating transformer. CONSTITUTION:A constant-voltage pulse generation circuit 1 feeding constant- voltage pulse to a rectifier circuit 3 on the output side through a transformer 2 is controlled by a constant-voltage controlling circuit 10. The controlling circuit 10 is composed of a coupled circuit 11 transferring feedback signal in a state that the input/output side is insulated, a feedback signal generation circuit 12 feeding back the feedback signal increasing commutation output when it is lower than rated voltage and lowering the output when it is higher than the voltage, through said coupled circuit 11, and a control signal output circuit 13 generating the commutation output lower than the rated voltage when the output signal of the coupled circuit 11 does not exist along with constant-voltage control. In this case, when a feedback system is interrupted by the failure of the coupled circuit 11 or the like, then the feedback signal disappears, but in response to this, said output circuit 13 directs the constant- voltage pulse generation circuit 1 to generate a commutation output lower than the rated voltage.
