Title: Manufacture of fine tube with inner groove
Inventor: ISHIBASHI AKIHIKO
IPC: B21H3/00
Filed: 1990-06-29
Abstract: PURPOSE:To manufacture the fine tube with inner groove of good heat transfer performance with high quality and with a very high productivity by making the outside diameter drop-rate of sinking drawing work to the specific rate, and making the thickness of the min. bottom thick part under the specific % of the outside diameter of the part to be roll-formed and further making the twisted angle of the roll-formed part of the inner grooved blank tube to the specific angle. CONSTITUTION:The premise is set that the sinking drawing work of off-line is executed on the condition of the range of the outside diameter drop-rate between 32%-48%, further, the min. wall thickness (wall thickness of the bottom part of the groove) of the blank tube with inner surface groove before the sinking drawing is made largely thinner than the conventional method, and made under 2.5% of the outside diameter of the roll formed part. And on the case for manufacturing the products with the groove of a little twisted angle, further by adding to the above two conditions, the blank tube with the inner surface groove to be roll formed is adjusted on the condition of the range of the twisted angle of the roll-formed part within the angle 28-36 deg., and is manufactured in making the twisted angle to a little by deforming with sinking drawing. On this invention, because the relation of the working condition of the sink drawing and the roll forming time is made proper, so the fine diameter tube with inner surface groove under 6mm of the outside diameter having the good heat transfer performance and the high quality can be manufactured with the very high productivity.

Title: Regenerative damping control method for electric motor car
Inventor: INABA YUTAKA
IPC: H02P3/14
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To obtain a control effect by regenerative damping by performing on-off control for the running speed during damping while varying the on-duty ratio in accordance with the change in running speed in such a manner that the running speed during damping will be increased at a predetermined rate of change in accordance with the drop in the running speed when switching end speed has not been obtained yet. SOLUTION: When the running speed of an electric motor car during damping has exceeded a switching end speed Vh set to a value higher than a velocity V0 corresponding to a noload speed of the motor, on-duty ratio is made to zero and switching means is held to OFF state. And the switching means is on-off controlled while varying the on-duty ratio in accordance with the change in the running speed so as to increase the on-duty ratio Db at a predetermined rate of change in accordance with a drop in the running speed when the running speed during damping is less than the switching end velocity Vh .

IPC: H01L39/24
Filed: 1985-08-07
Abstract: PURPOSE:To obtain the levelling process without generating burrs on the refilled SiO pattern after dry etching of an Nb and Nb group pattern by changing a resist used for the dry etching from a conventional positive resist into a negative resist to control the developing conditions of the resist. CONSTITUTION:After spreading an Nb film 32 on a substrate 31, a negative resist 33 is spin-coated, followed by baking. Then, pattern exposure is done and a square pattern is formed by development. Subsequently, an Nb pattern 32 is formed by plasma etching using CF4 gas and development is carried out again in order to form liftoff, thereby shrinking the bottom of the resist slightly to form a resist pattern 33 of overhand form. For keeping a quantity of said overhand within 0.1-0.3mum, the composition of a developing solution and time are controlled. An insulating film SiO34 is spread to refill to the same height as the Nb pattern 32. Next, liftoff is done using acetone to leave the Nb pattern 32 and the refilled SiO34 for levelling.

Abstract: PURPOSE:To improve the durability of an outside diameter side friction element by forming an inside diameter side, e.g., an O/D direct-clutch piston into a lubrication control means for discharging a lubricating oil toward the friction element of an outside diameter side, e.g., an O/D brake. CONSTITUTION:As a pressure oil is fed to a hydraulic actuator 42, a piston 52 is extended and its outside diameter side collar part presses a first friction engaging element C0 forming a connected condition. In this condition, the outside diameter side collar part 52a is brought into contact with the friction engaging element C0 and an oil sump whose inside diameter side is opened is formed by the outer peripheral wall 57 and the projecting part 59 of the piston 52. Hence, a lubricating oil which is fed by a hydraulic pump through a shaft center and which is outwardly splashed by a centrifugal force after lubricating other parts, is introduced into the oil sump from the opened inside diameter side. And, as the pressure oil in the hydraulic actuator 42 is drained to release the first friction engaging element C0, the piston 52 is separated from the friction engaging element C0 and the lubricating oil in the oil sump is fed into a second friction engaging element B0 from the gap between the collar part 52a and the friction engaging element C0.

Title: Head protective airbag device for front and rear seats
Inventor: ONO MITSUYOSHI
IPC: B60R21/20
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To increase the degree of freedom for designing an air conditioner blowing port by satisfying the storage performance of an airbag body. SOLUTION: A roughly rectangular notch 80 is formed from a lower side in a middle part between the front seat expansion room 46 and the rear seat expansion room 48 of an airbag body 16, and thin cloth 82 is disposed in this notch 80. The outer peripheral part 82A of the thin cloth 82 is fixed to the outer peripheral end 80A of the notch 80 by sewing, adhesion or the like. Thus, the volume of the middle part of the airbag body 16 composed of the thin cloth 82 in its folded state is set smaller than that when base cloth 17 having an equal area is folded. Thus, in a relatively small space formed in the lower side of a rear seat air conditioner blowing port, the middle part of the airbag body is easily stored.

Title: Method of adjusting rotational speed of turbine for marine use
Inventor: NAKANISHI KAZUO
IPC: B63H5/07
Filed: 1981-10-30
Abstract: PURPOSE:To reduce the resistance of a propeller to reduce the load of the turbine and reduce the load of the turbine at a critical rotational speed to shorten the turbine driving time at the critical rotational speed by blowing compressed air toward the propeller from the stern part when the rotational speed of the turbine approaches the critical rotational speed. CONSTITUTION:In a case where the rotational speed of the turbine is gradually increased upon the increase of the vessel speed, the rotational speed is measured. When the measured value approximates the critical rotational number, compressed air is blown off from a compressed air blow-off pipe 1 through a control valve 2 which is adjustable in its flow quantity. Then, compressed air is discharged in the from of air bubbles toward the propeller 3 at the stern part. Accordingly the resistance of the propeller 3 reduces, and the load of the turbine reduces to abruptly increase the rotational speed. Hence, it is possilbe to pass through a critical rotational speed region within a short period of time. Thereafter, the supply of the compressed air is stopped, and the turbine is operated at a predetermined rotational speed.
