Title: Rotary machine
Inventor: DEBUIDO JIYON HIRU
IPC: F16N31/02
Filed: 1978-12-12
Abstract: A rotary machine including a sump in which there is a rotatable part such as a crankshaft (16) or flywheel and an upper portion in which certain parts require lubrication has a lubrication system comprising a scraper (18) terminating at one end near the rotatable part and at its other end in the upper portion.

Title: Method and device for tracking type solar light electric generation
Inventor: FUJINO MITSUHIRA
IPC: F24S50/20
Filed: 1984-07-25
Abstract: PURPOSE:To improve light collecting efficiency by a method wherein the angle of a panel is adjusted intermittenly only in the North-South direction. CONSTITUTION:Sun tracking light detectors 10, 11 are attached to the panel in the north-south direction. When the altitude of sun is lower than the slant angle of the panel, direct sun beams are projected against the light detector 10 but the light detector 11 is in the shadow of the panel. The output of the light detector 10 begins to increase from a time when the light begins to shoot the detector 10 and a tracking mechanism is moved by the leading edge signal of the detector to change the slant angle of the panel. When the angle of the panel approaches vertical with respect to the incident light of the sun, the light detector 11, equipped at the north side of the panel, begins to receive the light of the sun and the electric output thereof is increased. When the angle of panel becomes vertical with respect to the incident light of sun, the outputs of the detectors 10, 11 becomes equal. When the electric outpts of both detectors 10, 11 become equal after comparison, a signal is outputted to stop the operation of the tracking mechanism.

Title: Control device for electric rolling stock
Inventor: NITSUTA SHIROU
IPC: B60M3/04
Filed: 1982-09-07
Abstract: PURPOSE:To omit a switch box and a converter on an electric rolling stock by providing a ground and vehicle information transmitter circuit which transmits a signal for controlling the supply of electric power to a trolley wire electrically insulated at every zone from the vehicle to a substation. CONSTITUTION:When an electric rolling stock is power driven, a power drive command is transmitted through a ground and vehicle information transmitter circuit which is composed of an information transmitter 19, a vehicle antenna 20 and an information transmission line 12 to a substation 14. Thus, the substation 14 energizes so that a trolley wire 10 becomes positive and a trolley wire 11 becomes negative. When the rolling stock is reversely driven, a reverse command is transmitted through the ground and vehicle information transmitter circuit to the substation 14. Thus, the substation 14 energizes so that the trolley wire 10 becomes negative and the trolley wire 11 becomes positive. In this manner, a switch box and a converter which are placed on the vehicle can be omitted.

IPC: F16C27/00
Filed: 1977-12-22
Abstract: PURPOSE: To increase the squeezing effect by supporting the bearing via a plurality of oil films formed between bearing base and housing.  
     CONSTITUTION: An annular space is formed between the outer wall of a housing 1 and the inner wall of a bearing base 12, and a ring-like partition member 18 dividing the space into inside and outside chambers 16 and 17 is secured via a plurality of spacers 19.

Title: Ignition device of plurality of sparks
Inventor: KAJIURA SUSUMU
IPC: F23Q3/00
Filed: 1982-09-08
Abstract: PURPOSE:To obtain discharge sparks with a long connecting time by a low cost and small size device and yet also adjust the output value at low cost and with ease by a method wherein a resistor is provided in parallel to a capacitor for flasher trigger. CONSTITUTION:The development of voltage in a primary wiring 22 due to the resonance between a resonant capacitor 8 and the primary wiring 22 develops voltage also in a feedback coil 21 in order to charge a capacitor 13 in a passage of a resistor 10, the capacitor 13, and a resistor 18. When the charging voltage of the capacitor 13 exceeds the generated voltage of the feedback coil 21 as the charging to the capacitor 13 proceeds, the charges stored in the capacitor 13 flows through a resistor 9 to the base of a thyristor 6 in order to turn the thyristor 6 on. When the resistor 12 is installed in parallel to the capacitor 13 for flasher trigger, the turn-on time of the thyristor 6 is changed by changing its gate current with the change of the value of the resistor 12. Consequently, the output energy can be easily adjusted.

Inventor: KOBAYASHI KEIJI
IPC: H01L21/20
Filed: 1981-09-30
Abstract: PURPOSE:To facilitate the desired crystallization of a silicon film formed on an amorphous insulating film by a method comprising the steps of piling up non- single crystal silicon films on the top of each other; radiating laser beams or electron beams to the silicon films before inplanting ions into them; and adding an annealing process thereto. CONSTITUTION:An oxidized film 2 is piled on top of a glass substrate 1. A nitrided film is piled on top of the film and periodic grooves are formed. Subsequently, a polysilicon film 4 is piled on the surface and ions 5 are implanted into the polysilicon film before laser beams 6 are radiated thereto. In so doing, the polysilicon 4 is annealed and single crystallized, so that a single crystal silicon filmis grown and formed. Since the implanted ions in the polysilicon film 4 act as the nucleus of the crystal during annealing, the single crystallization of the polysilicon film 4 is greatly facilitated. Moreover, because a nitrided film 3 is used as a ground layer for the polysilicon film 4, the grooves can be provided with extremely high accuracy.

Title: Controlling method of injection quantity of fuel in internal-combustion engine
Inventor: BETSUSHIYO HIRONORI
IPC: F02D41/06
Filed: 1982-09-09
Abstract: PURPOSE:To enhance operating performance in a low temperature condition, by a method wherein the maximum injection pulse width is corrected in accordance with cooling water temperature, and the maximum injection pulse width thus corrected is applied only when a fuel-air ratio tends to become low (lean). CONSTITUTION:The operation of a controlling circuit is expalined by referring to an interrupt routine. In step 502, a rotating speed N is taken in, and is stored into an RAM 108. In step 503, the maximum injection pulse width TPmax set for each value of the rotating speed N is read. In step 504, a cooling water temperature TW in a water temperature sensor 6 is taken in. When either of flags F1, F2 is ''1'' in steps 505, 506, the pulse width TPmax is increasingly corrected in step 507. The increasing correction value DELTATPmax is set to be higher as the water temperature TW is lower, and is stored in an ROM 109. In step 508, TPmax TPmax+DELTATPmax, and step 509 is entered. When both of the flags F1, F2 are ''0'' in steps 505, 506, the increasing correction of the pulse width TPmax is skipped, and step 509 in entered. Namely, by increasing the maximum injection pulse width at a low temperature for a predetermined period of time from the moment an idle switch 5-1 is changed over from ON to OFF (the moment a power switch 5-2 is changed over from OFF to ON), the quantity of a fuel adhered to the wall of a manifold pipe is compensated for, thereby enhancing the operating performance.
